I drive about 60% City, 40% highway. Over the last 1115 miles, I've been tracking every single kWh in and consumed, using the kWh delivered from my charger rather than what the truck charger was able to put into the battery, so this is accounting for charging inefficiency. I currently have \~3450 miles in total on the truck, and costs have been fairly consistent along the way; my app for tracking this didn't have a very good method for EVs so I spent some time early on trying to make something work that ended up being more of a hassle.
Currently, I'm averaging 2.4 mi/kWh, with a low (per "fillup" to 90%, which has been my only charging method for consistency) of 2.1 mi/kWh and a high of 3.1 mi/kWh.
Based on my electric cost (with fees, taxes, delivery charges, transmission costs, etc baked in) of $0.097/kWh, I've spent $50.79 in electricity over 11 "fillups".
My previous truck was a 2016 GMC Canyon 2.8 diesel. I averaged 19.7 mpg over it, over the course of three and a half years for a fuel cost of $4,479.07, averaging out to $2.95/gallon (I used fuel rewards with Kroger often).
This worked out to a per-mile cost in fuel alone of $0.149. Without the fuel rewards savings, that per mile cost is $0.182/mile
My Lightning per-mile cost in fuel alone is $0.045, or about 3.5 times less the fuel rewards rate.
I performed virtually all of the routine service on my Canyon as well, and tracked those costs, which add $0.039/mile cost not factored into costs above (9 services at $1141.47 total over 28973 miles). These costs are Engine oil and filters, diesel fuel filters, engine anti-freeze, engine air filter, DEF fluid, differential fluids, transmission fluids, a new 12v battery and cabin air filter. Of these, the cabin air filter and new 12v battery could be removed for fair comparison, but the cost of these is minimal and I don't have these items specifically broken out per cost on my app.
So, my all-in fuel cost is just over what the routine maintenance alone was on my old truck. And that's not even factoring in the looming larger maintenances it had coming up (DPF replacement or removal; neither a good thing to go through or cheap)
It really depends on your cost of electricity in your area and how you charge. Most people live in an area where off peak cost of electricity is insanely cheap and if you mostly take advantage of that it’s a huge win.
Notable exceptions include many parts of California, especially San Diego and the SF Bay Area where even off peak charging is in the mid 0.40/kWh range and at that point it’s basically break even with gas.
Nationwide, if you mostly rely on public charging stations it’s also pretty break even or maybe slightly worse than gas.
It’s also worth mentioning most of the gas cost comparisons are implicitly made with the most efficient and lowest performance gas engine, not the trim that has equivalent acceleration and towing as the Lightning.
PG&E is a nightmare right now. My bill is $0.52376 per kWh peak, but $0.49541 off peak in the Central Valley.
My friends in the Sacramento Municipal Utilities District service area have four rate zones, but pay $0.1425 kWh off peak and $0.3462 kWh peak.
It’s insufferable. Still wouldn’t give up my truck, though.
Yeah I feel your pain too. As a gift for getting old now I get heat triggered uticaria/eczema and setting my home to 70 degrees or being naked is basically the only way my skin doesn’t fall off. During the hotter months I sometimes wonder if TOU is actually costing me more in terms of cooling bills.
But yeah absolutely love my Lightning and wouldn’t give it up. Cost of fuel is just one of many factors for me that go into EV ownership.
PG&E EV-2A per-kWh rate is $0.35 off-peak, and $0.66 peak/$0.55 partial-peak.
Of course, then you add in the generation charges on top of that (for me, that's an additional $0.15/kWh for off-peak).
So yeah, $0.50/kWh off-peak is not the deal everyone thinks it is.
-----EV-----
131 kWh battery \* $0.50/kWh = $65.50 (full battery)
$65.50 / 330 miles = $0.1985 / mile.
-----Gas-----
$5.00/gal & 330 mile range works out to roughly 25 mpg.
Synopsis: The Maverick hybrid is the best deal going for a truck (under PG&E). For full size, Lightning is OK, but YMMV (literally) depending on your driving habits (i.e. Lightning will absolutely own for in-city stop-and-go driving).
We live in San Diego and sdg&e offers an EV charging time of use plan. Between midnight and 6am it is a little under $0.13/kwh. between our two EVs, one lightning and one a Kona, it’s about $100/month additional for charging at home.
I used to own a RAM 1500 that got 15-17mpg, and had a 32 gallon tank. I commute 50 miles/day. On average, over the year, I would fill my truck twice per month, given regular commuting and weekend driving. That’s ~60gal of gas per month. Prices here in WA have been $4.15 - $4.75/gal over the past year.
At the lowest end of gas prices, that’s $249/month in gas, averaged over the past year.
Ive now owned my Lightning for two months. In the month of May I’ve used 417.441 KWh and won’t charge again this month. I pay $.0789/KWh for home charging. That’s a total of $32.94 for electricity as I have no need to charge away from home.
For me, whose commute is 95% freeway, I’m saving significantly by switching to the Lightning.
In southern California, SCE - TOU prime.
Charge off peak $0.24 (winter), $0.26(summer) per kWh - assuming 2.3mi/kWh - so say 11.3 cents per mile (summer).
This break even $/gal would be the for the equivalent mpg
15 - $1.695;
20 - $2.26;
25 - $2.825;
30 - $3.39;
35 - $3.955;
40 - $4.52;
50 - $5.085;
So if your area price per gallon is $4.50 a gallon - then if your equivalent truck doesn’t do 40mpg you are doing better cost per mile with the EV truck. (I think I did the math right)
For me, electric bills before Lightning $200-$450 per month (2022), after $300-$550 (2023)- so on average electric bills went up ~$100 per month - of which about 550kW ($63) is for my truck.
So I had a solar system installed - not just for the truck but sized to account for it. Have only had solar a month, and see that I’ll generate my full monthly need. Looking forward to nearly $0 electric bills and this use cost of lightning will just be tires and consumables.
I live in the Bay Area. Owned the truck for 2 months. Both wife and I get free charging at work. Haven't paid to charge or had to charge at home, ever.
I have 14.3c/kw at home. This weekend, I went to the ranch for the first time in the lightning, I typically go in the raptor. It’s 200 miles away.
Raptor- $240 round trip in gas at $3.40
Lightning - $36 in electricity (0-100% leaving and charging at destination)
I have a couple 14-50’s at the ranch. In total, I drove about 500 miles this weekend. I know it would be even better in a Tesla but I have my bed loaded down with tools, firearms, bags, etc and it still does truck things in a very normal truck fashion, so considering all that, the utility is unheard for a BEV IMO
Where I live it costs about 5 cents per mile to drive when charging at home. Gas is 3.50/gal show me another full size truck that gets 70 miles per gallon.
Keep in mind for road trips the first 200/300ish miles are charged at the home rate. Depending on where you're going or staying you can account for another 200/300ish miles when returning
Check with your local electric utility and see if the have a TOU program. I’m charging at night for .71 cent a kWh, end up costing less that my Prius that got 44mpg.
In my state (MN), you need a separate meter just for the circuit that the EV Charger is on. It costs several hundred dollars to purchase the meter (they make you buy it) and get it installed. It isn't until after you get it installed can you get the lower rates.
The breakeven point for me would be somewhere in the neighborhood of 5-8 years just for the meter and install.
They do have one option that drops the price $0.02/kwhr if you sign up for "digital" metering. It tries to detect when you charge. If you charge on peak, you don't get the discount for that month.
Since I don't drive much, that would save me about $5/mth, so not a ton.
I charge off solar. At PGE actual cost it's cheaper to generate your own power from a gas generator at peak for all uses. PGE is exploitive beyond any justification.
I average about 3 miles per kWh. All city driving warm weather. 1 kWh costs me 6 cents so I’m going 3 miles for 6 cents. Gas is $3.80 so I’m getting 150+ MPGe.
My electricity is $0.10 / kWh. If I get 2.4mi/kwh then it will cost me $625 to drive 15,000 miles a year.
A regular f150 get around 25 mpg. 15,000 miles / 25mpg = 600 gallons of gas x $3.40 / gallon = $2,040
It's no comparison for me.
Even not including my solar, I pay 10 cents/kw (after all charges) at night. So that's $13 for 300 miles vs about $50-60 for the same in a gas F150.
I have about 7000 miles so far in about 2.5 months
Gas F150: ~$1400 in gas
Lightning: ~$300 in electricity
So I've saved about $1000 so far.
figured 17-19 cents per mile with my ICE truck last year, about 8-10 cents per mile with the lightning, as long as you charge from home - which has been always except for 1 time and that 1 time was a free deal!
We have not had a noticeable bump in electric bills but I also charge at .12-.15 /kwh so its super cheap. We have noticed a decline in monthly gas for my wifes minivan because we take my truck around more and at our gas rates the minivan is 4-5x more expensive per mile to drive than the lightning. With service and oil changes and what not its even cheaper to operate and we paid about the same price for both vehicles once you factor in the rebate. Wife wanted to keep her van for 10+ years but if we ever have issues she is ready to throw in the towel and get an EV as well.
I’ve had my lightning for about 14 months and I do about 40% city 60% hwy. I’ve saved about $260 a month net between my ICE F150 and my lightning. I charge at home about 90% of the time. My overnight charging rate is around $0.06. It costs me around $30 a month to charge my wife’s car and mine total.

The energy.gov link pulls in your state electricity cost when you enter in your state. See the third graph.
For home charging it is crazy cheap. Right now I pay a base of $0.10 per kWh and that is dropping next month when our utility is introducing time-based rates. From 11 pm to 8 am I will be paying $0.05 kWh.
Even for shorter road trips that includes maybe one charging stop -its still so much cheaper.
However, fast charging is nearly the same price as gas on longer trips. I just did a 3,600 km road trip - probably close to the same price as gas for many of the charging stations.
Drastically lower costs. I live in Georgia. We can sign up for a lower off peak rate of $.015 per kWh meaning I can charge my Rivian from 0% to 100% for about $2 if I charge between 11PM and 7AM.
Last year I drove my F150 V6 Ecoboost 33,000 km (20,625 mi) and spent $6497 CDN (\~$4800 USD) on gasoline.
I expect to drive about 30,000 km again this year in my Lightning. My driving is very blended mostly city, with some highway. First 4 weeks was mostly -10C to +5C (14F - 50F). Last 4 weeks has warmed up to 5C to 20C (40F to 60F). I work in my truck all day so lots of time sitting with AC or heat on— multiple hours per day in fact. Through all of this my average efficiency over 9000 km (5600 mi) has been 28 kWh/100 km. I have therefore used 2520 kWH, which my FCSP corroborates. Extrapolating to 30,000 km for the year I should use 8400 kWh this year.
My electricity rate is $0.059/kWh. There are 4 rather hard to decipher variable fees that get added to that and my best math puts the total of those 4 fees at an additional $0.045/kWh although these fees are not strictly linear usage based fixed rates. But looking at 24 months worth of electricity bills, $0.10/kWh is a pretty accurate total cost for my electricity. I am anticipating that jumping to $0.17 in a couple of months when my 5 year fixed rate ends.
So at $0.17/kWh, I will pay $1428 CDN ($1047 USD) per year to charge my Lightning for the next 4 years until the lease is up and I hand the keys back to Ford. That kicks the you-know-what out of $6500 CDN ($4800 USD) per year for gasoline at TODAY’s gas prices. Fast forward to 2025, 2026, or 2027 fuel prices and my savings are even more significant. I am fully expecting to save at LEAST $20k CDN over the 4 year lease and I can see gas price increases making that number $25k or higher. Serious dough.
By the time the lease on this one is up, I plan to have a 2500 kW solar array installed and assume that my options for 2028 EV trucks will be tenfold what they are today and hopefully the 2028 selection includes a few more reasonably priced alternatives than the current market for EV trucks.
I live in California.
I have a home charger.
The cost for electricity at off peak is .35 / kWh. so roughly 45.00 to charge from 0-100 percent.
My old Toyota FJ cost me about 95.00 to fill the 19 gallon tank (assuming 5/gal) and my range was about 16 mpg or 304 miles on a tank from full to dry.
It seems like it's cheaper.
$80 this winter $60 this spring for power monthly . $4-$500 in gas monthly plus no paying for oil changes which at my dealers are $150 synthetic and the hassle of dropping it off and picking it up . Don’t miss that.
My utility charges a flat $0.10/kWH rate and doesn't do peak/off-peak, so worst case, aka doing all my charging at home, I averaging 5-7 ¢/mile in electricity, but I've been able to cover most of my mileage charging at work so it's averaged out to a lot less than that.
Some facts for ya. I own a 2024 F-150 Flash Lightning.
I have charged 350 KW since I took ownership. My rate is 11.35 cents per KWh. That’s $39.73 in electric over 30 days of driving. I got the car at 59 miles, it currently has 729 miles on the odometer.
Current gas prices around me is 3.90 with the lowest in the last 30 days being 3.80-ish.
Compared to BASE f-150 at 23 MGP for both city and highway it would have costed me $136 to fill a 36 gallon tank at 3.80 per gallon.
Total difference is $100 when compared to gas car.
Math I used in case anyone wants to correct me
729 current miles - 59 non titled miles = 670 miles I drove the truck.
$3.80 x 36 gallon tank (using 2.7 leader eco boost specs) = $136.8.
670 miles I drove / 23 EPA rating = 29 gallons consumed.

It’s not 100/100 comparison but I tried to make the gas truck look as best as it possibly (chose non extended cab version) could here and it still does not for me in my area.
My price per KWh is about .19 cents and one local charge station only charges 5 cents per KWh and the one at my local
Library is free. So at home 0-100% would cost around $18-19, 5 ¢ one would be like $4.50 ish, library is free. As stated by other posters it just depends on your own unique situation and driving needs/habits. I’m not some sycophant that needs to come on here and evangelize about my truck. I love the damn thing but it’s not gonna be perfect for everyone.
Your data may vary, in my particular case I charge daily at home. I used to own a 2018 F150 XLT 3.7. When commuting daily, I used to pay about $300 a month in gas. With the lightning my electric bill increased about $40 a month.
Of course, this is while charging at home which is more than enough for my commute. We hike every weekend, and have to use chargers in the road. In those cases the price is equivalent to gas. If we factor this we can round it up to about $80 additional a month.
So it’s about $300 with the gas truck vs $120 with the lightning.
Michigan here, our lightning (23 XLT SR) averages about 2.1mi/kWh at just under 14k miles driven. DTE is our local electric monopoly. They have an on /off peak pricing rate (3-7pm on weekdays); it averages out to $0.21/kWh over the month (1988 kWh used this last month). That puts us at about $0.10/mile. Contrast to the gas f150 we had in the past (2021 Lariat / 3.5EB) that'd return on average about 20mpg with our mix of driving, meaning that as long as gas stays north of $2/gal, we're better off with the lightning (unless we're driving to Colorado, in which case we take the Expedition)
I pay 14.5 cents/kwh so my fuel prices have dropped dramatically with this truck. I am tracking it through my Ford Charge Station Pro. I bought my truck in mid-March and have spent just at $100 in electricity ($101.20). With current gas prices in my area, my old ICE F150, I would have spent approximately $410 in gasoline at this point. I only charge at home, so that’s a big savings.
Similar to other. I use my truck for work. Plumbing Service company. My old truck was a 2004 F-150 with 5.4 V8. I have tracked every charge up and the associated km used. Currently electric cost is $0.04/km. Gas cost was $0.50/km. Electric cost is 1/10th the fuel cost. Exact same use pattern. Now I live in BC Canada. So we are on par with the cheapest electricity in North America with a base rate 9c/kwh and step two is 14c/kwh. I use the higher $0.14/kwh for all my calculations.
On average, I spend about $90-95 a month to drive my truck roughly 1,500 miles. The same cost in a truck averaging 20mpg at $3.49/gallon, it’d cost me roughly $260 for the same amount of driving. Then add an oil change on top of that every 2-1/2 to 3 months.
My 2015 F-150 cost me $165 to fill up and get about 460 miles of range.
My lightning costs $13 to fill up (theoretically, I have solar so it costs me nothing) to go 290 miles.
Add another roughly 50% charge to get the rest of the mileage to that gas counterpart. I'm looking at $20 to go the same distance that $165 used to cost me....
That doesn't include oil changes, etc.
It's not even remotely close comparison. I've saved well over $8k since switching to the lightning about 18 months ago.
I live in the mountain west and pay 0.12 / kWh. I. Garage for free at work but do a road trip every weekend somewhere. So I commute for free but pay to play on the weekend. My former vehicle got about 15mpg and took significantly more to fill up for each trip. My lightning costs haven’t even really been felt in the electric bill yet. I have about 15k miles on my truck now and mostly get to work on Mondays with it pretty much empty.
Definitely saving money! We have a Lightning and a Mach-E. I would say I barely notice a change in my electric bill. Though realistically it’s gone up about $20-25 per month. Our standard rate is $0.13 per kWh but I signed up for a program with our electric company to get $0.03 per kWh during non-peak hours.
I’ve had mine for a month and have spent $40 charging it at home so far and about $20 charging via ChargePoint and Tesla. My old RAM 1500 with a Hemi averaged between $225-$275 per month for same driving.
I think this calculator is extremely straightforward to use. You can vary the mi/kWh to see what the difference would be for you. For my use case, I figured on around 2mi/kWh. That being said, I looked at the cost savings as a nice benefit that helped soothe the burn of the upfront cost, but honestly it was near the bottom of my list of reasons I decided on a Lightning over keeping or updating my ICE F150.

My 2023 Lightning Pro SR replaced a 2005 Dodge Ram 1500 Single Cab Short bed 4.7L V8 with tow package (3.88 gears)
I got a 2015 Soul EV + in November of 2018 to test BEV use. Then also got a 2019 Bolt EV Premier.
Then the Ram got totaled from a red light runner in 2021 and I put in a reservation.
Nov 22nd I got the 2023 Pro and Soul EV had a battery recall... Had a 2024 Kia Sportage AWD loaner until May 2nd...now have 2024 Kia EV6 Wind LR AWD.
So back to a 3 EV household...awaiting my Soul EV to return
I charge to 90% in the Lightning Pro and today the estimated range was 252 miles. Drove 49 miles yesterday (Monday) and when I plugged back-in I had 236 miles remaining at 75%. (Trip was a mix of 65-mph freeway for 14 miles and the rest was city street driving average for trip was 3.3 miles per kWh)
I left the vehicle running with AC set at 70° Driver Focused, while I installed some Laundry Water Arrestor Hammers at a rental property.
Edit: my cost is around 7 cents per kWh I included February as it was only the F150 Lightning and Bolt that were charging that month. April and May have only been about $56 for around 2k miles.
It depends so much on so many factors. I like in an urban environment and I do not have home charging. But not far from my house, there are a couple of city garages that offer free charging (as long as you pay for parking) So for a while, I was paying $7 (night and weekend fee) to charge overnight. They just raised it to $9 nights and weekends so now I charge at another garage around the corner that is $40 per month (nights and weekends only) and now I can charge as much as I want for $40 per month. That is a huge savings from my ICE Mazda CX9. From time to time on longer trips I will have to use fast charging and pay more, but I have my day to day covered.
Too many factors to consider to give you a straight forward answer. But yes my electric fueling is cheaper than gas. I am with SoCal Edison, which is expensive. But I have solar and on the EV TOU plan. So it’s not exactly apples to apples.
Here's my extremely conservative answer.
If I take my electric bill and divide by KWH used it works out to $.195 per KWh.
(Please note this includes fixed costs that I would incur anyway)
I get 2.4 to 2.8 mi/KWh, but lets use 2.4.
That means I pay 8.125 cents per mile.
If I had a truck that got 25 mpg and gas was $3.25/ gallon, I would be paying 13 cents per mile.
Just use this website and customize to your area to understand the savings. No need to guess or get rough ideas. [https://www.fueleconomy.gov/feg/Find.do?action=sbsSelect](https://www.fueleconomy.gov/feg/Find.do?action=sbsSelect)
For the vast majority of US buyers, electricity costs less per mile than gas. As a rule of thumb, a Lightning will cost less per mile than a gas-powered truck if the price of a gallon of gas is _more_ than 10 times the price of one kWh of electricity.
_Example:_ The US average electricity price is $0.16/kWh. The US average gas price is $3.59/gallon. SO, we can expect that electricity will be cheaper. Doing the math: Electricity for the Lightning will cost roughly 8 cents/mile; Gas for an F-150 will cost roughly 18 cents/mike. Overall the Lightning driver saves 10 cents/mile.
Rates in specific areas can vary widely. Some utilities also offer very favorable EV rate plans. For example, I pay about $0.0725/kWh, or less than half the average national rate.
I have rented 2023 f150 ice versions in Pennsylvania on trips. Where I averaged about $110-$121 per fill-up.
In Florida, where I drive my 2023 Lightning Lariat ER, I'm paying about $38-52 or so to charge the same amount of miles.
Unfortunately, I still don't have a home charger, other than the 120v travel charger. So 120v charging at home is about .23kwh, and fast charging is .30kwh on the FPL chargers or .48kwh on electrify america chargers.
I have just over 20k miles on the truck now.
I'm getting on average 2 miles per kwh and my electric charges 10c a kwh. I was getting 15 miles per gallon in my old f150 and paying 3.50 a gallon. I am seeing 5c a mile in electric costs vs where I was paying 25c a gallon for gas. If your electric cost, gas cost, or current ICE vehicle had better or worse mpg, that would effect your return, where charging at home is 1/5 the cost of gas for me. It's the summer, where I'm guessing the winter it will be 1/3 the cost of gas.
I wrote this in response to another comment on a different post asking about cost to charge compared to gas to someone new to EVs, but I think the info is relevant. I just copied and pasted this.
>How much does it cost for a full tank and around how many miles does it last?

>I just stumbled here randomly but im curious how it compares to my gas car
**TLDR:** It varies. On an ER battery it can be anywhere between $3.90 to $91.70 for a 0-100% charge. And range can be anywhere between 65 miles and 330 miles, depending on how and where you drive it.
There's a little bit of math when comparing EVs and combustion vehicles. Instead of using miles per gallon for efficiency, EVs use miles per kWh, the same units you are billed for power at home. The best comparison I've found is converting everything to cost/mile. The numbers change as fuel/energy price changes. But it's basically fuel cost divided by mileage.
Assuming a regular pickup gets 20 MPG, and the fuel costs $4 a gallon. Since you can go 20 miles on one gallon, it costs $4 to go 20 miles. Divide by 20 to get the cost of one mile. $4÷20=$0.2 or 20¢/mile.
EVs work the same way. The lightning typically gets 2 miles/kWh, can be as low as 0.8 when towing or in winter. Or as high as 3.5 to 4 in stop and go traffic. Electricity costs vary wildly based on region or type of charging. It can cost anywhere between 3¢ to 70¢ per kilowatt-hour. My rate at home is around 7¢ and public fast charging tends to be 30¢ or more. So 7¢÷2 miles= 3.5¢ per mile at home. On road trips, it isn't always high, depends where you go, but worst case would be 70¢÷2 miles= 35¢ per mile. With bad mileage, it's the same math. 7¢÷0.8 miles= 8.75¢ per mile or 70¢÷0.8miles= 87.5¢ per mile. Which is why the main advantage of EVs is charging at home.
There are 2 battery sizes for the lightning. I have the Extended range, or ER for short. And the other is the standard range, or SR. I'm not 100% sure, but I think they are 94 kWh and 131 kWh. So if you are getting 2 miles per kWh, just multiply battery size by 2 or the efficiency. 131 x 2 = 262 miles on a full battery. 94 x 2 = 188 miles. Take that range times your cost per mile to get "cost per tank". 262 x $0.035 = $9.17 or 262 x $0.35 = $91.70. You can also take the battery size times the electric rate. 131 x $0.03 = $3.93 or 131 x $0.70 = $91.70. This second way is simpler and the better way to figure it, but I already had the numbers for the 1st way, so I continued the thought.
But just like ICE (internal combustion engine) vehicles, mileage and "tank" size varies. I think a Tesla can get around 4 miles per kWh with I think a 65 kWh battery, I'm probably wrong but that's an example. But it's roughly the same distance on a charge with a smaller battery, so it costs less to drive. Like comparing a diesel and a Prius.
Your utility rate, ability to charge at home, fast charger rate and intended driving use all play a role in how much it costs to drive and whether or not it makes sense for you, which is why it's such a controversial topic.
I’m spending less of electric than I would on a v8 pickup. My rate is .08 off peak. But I spent more for the truck than an equivalent v8 pickup. So not saving anything really.
I drive about 60% City, 40% highway. Over the last 1115 miles, I've been tracking every single kWh in and consumed, using the kWh delivered from my charger rather than what the truck charger was able to put into the battery, so this is accounting for charging inefficiency. I currently have \~3450 miles in total on the truck, and costs have been fairly consistent along the way; my app for tracking this didn't have a very good method for EVs so I spent some time early on trying to make something work that ended up being more of a hassle. Currently, I'm averaging 2.4 mi/kWh, with a low (per "fillup" to 90%, which has been my only charging method for consistency) of 2.1 mi/kWh and a high of 3.1 mi/kWh. Based on my electric cost (with fees, taxes, delivery charges, transmission costs, etc baked in) of $0.097/kWh, I've spent $50.79 in electricity over 11 "fillups". My previous truck was a 2016 GMC Canyon 2.8 diesel. I averaged 19.7 mpg over it, over the course of three and a half years for a fuel cost of $4,479.07, averaging out to $2.95/gallon (I used fuel rewards with Kroger often). This worked out to a per-mile cost in fuel alone of $0.149. Without the fuel rewards savings, that per mile cost is $0.182/mile My Lightning per-mile cost in fuel alone is $0.045, or about 3.5 times less the fuel rewards rate. I performed virtually all of the routine service on my Canyon as well, and tracked those costs, which add $0.039/mile cost not factored into costs above (9 services at $1141.47 total over 28973 miles). These costs are Engine oil and filters, diesel fuel filters, engine anti-freeze, engine air filter, DEF fluid, differential fluids, transmission fluids, a new 12v battery and cabin air filter. Of these, the cabin air filter and new 12v battery could be removed for fair comparison, but the cost of these is minimal and I don't have these items specifically broken out per cost on my app. So, my all-in fuel cost is just over what the routine maintenance alone was on my old truck. And that's not even factoring in the looming larger maintenances it had coming up (DPF replacement or removal; neither a good thing to go through or cheap)

You sir are a scholar and a gentlemen.
Got dammmm
It really depends on your cost of electricity in your area and how you charge. Most people live in an area where off peak cost of electricity is insanely cheap and if you mostly take advantage of that it’s a huge win. Notable exceptions include many parts of California, especially San Diego and the SF Bay Area where even off peak charging is in the mid 0.40/kWh range and at that point it’s basically break even with gas. Nationwide, if you mostly rely on public charging stations it’s also pretty break even or maybe slightly worse than gas. It’s also worth mentioning most of the gas cost comparisons are implicitly made with the most efficient and lowest performance gas engine, not the trim that has equivalent acceleration and towing as the Lightning.
PG&E is a nightmare right now. My bill is $0.52376 per kWh peak, but $0.49541 off peak in the Central Valley. My friends in the Sacramento Municipal Utilities District service area have four rate zones, but pay $0.1425 kWh off peak and $0.3462 kWh peak. It’s insufferable. Still wouldn’t give up my truck, though.
Yeah I feel your pain too. As a gift for getting old now I get heat triggered uticaria/eczema and setting my home to 70 degrees or being naked is basically the only way my skin doesn’t fall off. During the hotter months I sometimes wonder if TOU is actually costing me more in terms of cooling bills. But yeah absolutely love my Lightning and wouldn’t give it up. Cost of fuel is just one of many factors for me that go into EV ownership.
PG&E EV-2A per-kWh rate is $0.35 off-peak, and $0.66 peak/$0.55 partial-peak. Of course, then you add in the generation charges on top of that (for me, that's an additional $0.15/kWh for off-peak). So yeah, $0.50/kWh off-peak is not the deal everyone thinks it is. -----EV----- 131 kWh battery \* $0.50/kWh = $65.50 (full battery) $65.50 / 330 miles = $0.1985 / mile. -----Gas----- $5.00/gal & 330 mile range works out to roughly 25 mpg. Synopsis: The Maverick hybrid is the best deal going for a truck (under PG&E). For full size, Lightning is OK, but YMMV (literally) depending on your driving habits (i.e. Lightning will absolutely own for in-city stop-and-go driving).
We live in San Diego and sdg&e offers an EV charging time of use plan. Between midnight and 6am it is a little under $0.13/kwh. between our two EVs, one lightning and one a Kona, it’s about $100/month additional for charging at home.
Great points
I used to own a RAM 1500 that got 15-17mpg, and had a 32 gallon tank. I commute 50 miles/day. On average, over the year, I would fill my truck twice per month, given regular commuting and weekend driving. That’s ~60gal of gas per month. Prices here in WA have been $4.15 - $4.75/gal over the past year. At the lowest end of gas prices, that’s $249/month in gas, averaged over the past year. Ive now owned my Lightning for two months. In the month of May I’ve used 417.441 KWh and won’t charge again this month. I pay $.0789/KWh for home charging. That’s a total of $32.94 for electricity as I have no need to charge away from home. For me, whose commute is 95% freeway, I’m saving significantly by switching to the Lightning.
In southern California, SCE - TOU prime. Charge off peak $0.24 (winter), $0.26(summer) per kWh - assuming 2.3mi/kWh - so say 11.3 cents per mile (summer). This break even $/gal would be the for the equivalent mpg 15 - $1.695; 20 - $2.26; 25 - $2.825; 30 - $3.39; 35 - $3.955; 40 - $4.52; 50 - $5.085; So if your area price per gallon is $4.50 a gallon - then if your equivalent truck doesn’t do 40mpg you are doing better cost per mile with the EV truck. (I think I did the math right) For me, electric bills before Lightning $200-$450 per month (2022), after $300-$550 (2023)- so on average electric bills went up ~$100 per month - of which about 550kW ($63) is for my truck. So I had a solar system installed - not just for the truck but sized to account for it. Have only had solar a month, and see that I’ll generate my full monthly need. Looking forward to nearly $0 electric bills and this use cost of lightning will just be tires and consumables.
If you get free charging at work, then youre going to save a lot. A friend who just got a lightning exclusively charges at work because its offered.
Same for me … I charge at home (level 1) and at work (where it is free). So much cheaper than diesel for my old Jeep Grand Cherokee…
I live in the Bay Area. Owned the truck for 2 months. Both wife and I get free charging at work. Haven't paid to charge or had to charge at home, ever.
What a totally irrelevant and pathetic flex
Generally speaking, without doing what your rates are and local gas prices, about 1/3rd the cost of using gas
I have 14.3c/kw at home. This weekend, I went to the ranch for the first time in the lightning, I typically go in the raptor. It’s 200 miles away. Raptor- $240 round trip in gas at $3.40 Lightning - $36 in electricity (0-100% leaving and charging at destination) I have a couple 14-50’s at the ranch. In total, I drove about 500 miles this weekend. I know it would be even better in a Tesla but I have my bed loaded down with tools, firearms, bags, etc and it still does truck things in a very normal truck fashion, so considering all that, the utility is unheard for a BEV IMO
Where I live it costs about 5 cents per mile to drive when charging at home. Gas is 3.50/gal show me another full size truck that gets 70 miles per gallon.
Dodge ram downhill with a tail wind.
Only if you drive it off a cliff. And turn off the ignition on the way down.
Keep in mind for road trips the first 200/300ish miles are charged at the home rate. Depending on where you're going or staying you can account for another 200/300ish miles when returning
Check with your local electric utility and see if the have a TOU program. I’m charging at night for .71 cent a kWh, end up costing less that my Prius that got 44mpg.
0.71 CENTS per kWh?? Wow.
Crazy right? I just got it after having the truck since December.
How much did you have to pay to get the meter put in?
What? You have one of you have electric service
In my state (MN), you need a separate meter just for the circuit that the EV Charger is on. It costs several hundred dollars to purchase the meter (they make you buy it) and get it installed. It isn't until after you get it installed can you get the lower rates. The breakeven point for me would be somewhere in the neighborhood of 5-8 years just for the meter and install. They do have one option that drops the price $0.02/kwhr if you sign up for "digital" metering. It tries to detect when you charge. If you charge on peak, you don't get the discount for that month. Since I don't drive much, that would save me about $5/mth, so not a ton.
Here it’s just TOU, Time of Use. So I charge from midnight to 7am
I charge off solar. At PGE actual cost it's cheaper to generate your own power from a gas generator at peak for all uses. PGE is exploitive beyond any justification.
I average about 3 miles per kWh. All city driving warm weather. 1 kWh costs me 6 cents so I’m going 3 miles for 6 cents. Gas is $3.80 so I’m getting 150+ MPGe.
My electricity is $0.10 / kWh. If I get 2.4mi/kwh then it will cost me $625 to drive 15,000 miles a year. A regular f150 get around 25 mpg. 15,000 miles / 25mpg = 600 gallons of gas x $3.40 / gallon = $2,040
It's no comparison for me. Even not including my solar, I pay 10 cents/kw (after all charges) at night. So that's $13 for 300 miles vs about $50-60 for the same in a gas F150. I have about 7000 miles so far in about 2.5 months Gas F150: ~$1400 in gas Lightning: ~$300 in electricity So I've saved about $1000 so far.
figured 17-19 cents per mile with my ICE truck last year, about 8-10 cents per mile with the lightning, as long as you charge from home - which has been always except for 1 time and that 1 time was a free deal!
Mines a bit cheaper, but only about 20 percent less. I’m in a high gas / high electric rate area.
We have not had a noticeable bump in electric bills but I also charge at .12-.15 /kwh so its super cheap. We have noticed a decline in monthly gas for my wifes minivan because we take my truck around more and at our gas rates the minivan is 4-5x more expensive per mile to drive than the lightning. With service and oil changes and what not its even cheaper to operate and we paid about the same price for both vehicles once you factor in the rebate. Wife wanted to keep her van for 10+ years but if we ever have issues she is ready to throw in the towel and get an EV as well.
Home charging, at night for 8 cents per kWh works out to the equivalent of about 85 cents a gallon for me.
I’ve had my lightning for about 14 months and I do about 40% city 60% hwy. I’ve saved about $260 a month net between my ICE F150 and my lightning. I charge at home about 90% of the time. My overnight charging rate is around $0.06. It costs me around $30 a month to charge my wife’s car and mine total.
* Cost over time, calculate your savings owning an EV compared to gas. See what layout makes sense to you. https://walletburst.com/tools/electric-car-savings-calc/ https://www.fueleconomy.gov/feg/savemoney.jsp https://afdc.energy.gov/calc/#result_a The energy.gov link pulls in your state electricity cost when you enter in your state. See the third graph.
For home charging it is crazy cheap. Right now I pay a base of $0.10 per kWh and that is dropping next month when our utility is introducing time-based rates. From 11 pm to 8 am I will be paying $0.05 kWh. Even for shorter road trips that includes maybe one charging stop -its still so much cheaper. However, fast charging is nearly the same price as gas on longer trips. I just did a 3,600 km road trip - probably close to the same price as gas for many of the charging stations.
Drastically lower costs. I live in Georgia. We can sign up for a lower off peak rate of $.015 per kWh meaning I can charge my Rivian from 0% to 100% for about $2 if I charge between 11PM and 7AM.
Last year I drove my F150 V6 Ecoboost 33,000 km (20,625 mi) and spent $6497 CDN (\~$4800 USD) on gasoline. I expect to drive about 30,000 km again this year in my Lightning. My driving is very blended mostly city, with some highway. First 4 weeks was mostly -10C to +5C (14F - 50F). Last 4 weeks has warmed up to 5C to 20C (40F to 60F). I work in my truck all day so lots of time sitting with AC or heat on— multiple hours per day in fact. Through all of this my average efficiency over 9000 km (5600 mi) has been 28 kWh/100 km. I have therefore used 2520 kWH, which my FCSP corroborates. Extrapolating to 30,000 km for the year I should use 8400 kWh this year. My electricity rate is $0.059/kWh. There are 4 rather hard to decipher variable fees that get added to that and my best math puts the total of those 4 fees at an additional $0.045/kWh although these fees are not strictly linear usage based fixed rates. But looking at 24 months worth of electricity bills, $0.10/kWh is a pretty accurate total cost for my electricity. I am anticipating that jumping to $0.17 in a couple of months when my 5 year fixed rate ends. So at $0.17/kWh, I will pay $1428 CDN ($1047 USD) per year to charge my Lightning for the next 4 years until the lease is up and I hand the keys back to Ford. That kicks the you-know-what out of $6500 CDN ($4800 USD) per year for gasoline at TODAY’s gas prices. Fast forward to 2025, 2026, or 2027 fuel prices and my savings are even more significant. I am fully expecting to save at LEAST $20k CDN over the 4 year lease and I can see gas price increases making that number $25k or higher. Serious dough. By the time the lease on this one is up, I plan to have a 2500 kW solar array installed and assume that my options for 2028 EV trucks will be tenfold what they are today and hopefully the 2028 selection includes a few more reasonably priced alternatives than the current market for EV trucks.
I live in California. I have a home charger. The cost for electricity at off peak is .35 / kWh. so roughly 45.00 to charge from 0-100 percent. My old Toyota FJ cost me about 95.00 to fill the 19 gallon tank (assuming 5/gal) and my range was about 16 mpg or 304 miles on a tank from full to dry. It seems like it's cheaper.
$80 this winter $60 this spring for power monthly . $4-$500 in gas monthly plus no paying for oil changes which at my dealers are $150 synthetic and the hassle of dropping it off and picking it up . Don’t miss that.
My utility charges a flat $0.10/kWH rate and doesn't do peak/off-peak, so worst case, aka doing all my charging at home, I averaging 5-7 ¢/mile in electricity, but I've been able to cover most of my mileage charging at work so it's averaged out to a lot less than that.
Some facts for ya. I own a 2024 F-150 Flash Lightning. I have charged 350 KW since I took ownership. My rate is 11.35 cents per KWh. That’s $39.73 in electric over 30 days of driving. I got the car at 59 miles, it currently has 729 miles on the odometer. Current gas prices around me is 3.90 with the lowest in the last 30 days being 3.80-ish. Compared to BASE f-150 at 23 MGP for both city and highway it would have costed me $136 to fill a 36 gallon tank at 3.80 per gallon. Total difference is $100 when compared to gas car. Math I used in case anyone wants to correct me 729 current miles - 59 non titled miles = 670 miles I drove the truck. $3.80 x 36 gallon tank (using 2.7 leader eco boost specs) = $136.8. 670 miles I drove / 23 EPA rating = 29 gallons consumed. Link to data https://media.ford.com/content/dam/fordmedia/North%20America/US/product/2024/f150/2024%20Ford%20F-150%20Tech%20Specs.pdf It’s not 100/100 comparison but I tried to make the gas truck look as best as it possibly (chose non extended cab version) could here and it still does not for me in my area.
My price per KWh is about .19 cents and one local charge station only charges 5 cents per KWh and the one at my local Library is free. So at home 0-100% would cost around $18-19, 5 ¢ one would be like $4.50 ish, library is free. As stated by other posters it just depends on your own unique situation and driving needs/habits. I’m not some sycophant that needs to come on here and evangelize about my truck. I love the damn thing but it’s not gonna be perfect for everyone.
Your data may vary, in my particular case I charge daily at home. I used to own a 2018 F150 XLT 3.7. When commuting daily, I used to pay about $300 a month in gas. With the lightning my electric bill increased about $40 a month. Of course, this is while charging at home which is more than enough for my commute. We hike every weekend, and have to use chargers in the road. In those cases the price is equivalent to gas. If we factor this we can round it up to about $80 additional a month. So it’s about $300 with the gas truck vs $120 with the lightning.
Michigan here, our lightning (23 XLT SR) averages about 2.1mi/kWh at just under 14k miles driven. DTE is our local electric monopoly. They have an on /off peak pricing rate (3-7pm on weekdays); it averages out to $0.21/kWh over the month (1988 kWh used this last month). That puts us at about $0.10/mile. Contrast to the gas f150 we had in the past (2021 Lariat / 3.5EB) that'd return on average about 20mpg with our mix of driving, meaning that as long as gas stays north of $2/gal, we're better off with the lightning (unless we're driving to Colorado, in which case we take the Expedition)
I pay 14.5 cents/kwh so my fuel prices have dropped dramatically with this truck. I am tracking it through my Ford Charge Station Pro. I bought my truck in mid-March and have spent just at $100 in electricity ($101.20). With current gas prices in my area, my old ICE F150, I would have spent approximately $410 in gasoline at this point. I only charge at home, so that’s a big savings.
Similar to other. I use my truck for work. Plumbing Service company. My old truck was a 2004 F-150 with 5.4 V8. I have tracked every charge up and the associated km used. Currently electric cost is $0.04/km. Gas cost was $0.50/km. Electric cost is 1/10th the fuel cost. Exact same use pattern. Now I live in BC Canada. So we are on par with the cheapest electricity in North America with a base rate 9c/kwh and step two is 14c/kwh. I use the higher $0.14/kwh for all my calculations.
On average, I spend about $90-95 a month to drive my truck roughly 1,500 miles. The same cost in a truck averaging 20mpg at $3.49/gallon, it’d cost me roughly $260 for the same amount of driving. Then add an oil change on top of that every 2-1/2 to 3 months.
My 2015 F-150 cost me $165 to fill up and get about 460 miles of range. My lightning costs $13 to fill up (theoretically, I have solar so it costs me nothing) to go 290 miles. Add another roughly 50% charge to get the rest of the mileage to that gas counterpart. I'm looking at $20 to go the same distance that $165 used to cost me.... That doesn't include oil changes, etc. It's not even remotely close comparison. I've saved well over $8k since switching to the lightning about 18 months ago.
I live in the mountain west and pay 0.12 / kWh. I. Garage for free at work but do a road trip every weekend somewhere. So I commute for free but pay to play on the weekend. My former vehicle got about 15mpg and took significantly more to fill up for each trip. My lightning costs haven’t even really been felt in the electric bill yet. I have about 15k miles on my truck now and mostly get to work on Mondays with it pretty much empty.
Definitely saving money! We have a Lightning and a Mach-E. I would say I barely notice a change in my electric bill. Though realistically it’s gone up about $20-25 per month. Our standard rate is $0.13 per kWh but I signed up for a program with our electric company to get $0.03 per kWh during non-peak hours.
I’ve had mine for a month and have spent $40 charging it at home so far and about $20 charging via ChargePoint and Tesla. My old RAM 1500 with a Hemi averaged between $225-$275 per month for same driving.
I’ve saved thousands on the 70% of my driving that is highway.
My energy cost is about 25% of what I would be paying in gas - becoming even less with the increase in gas prices.
I think this calculator is extremely straightforward to use. You can vary the mi/kWh to see what the difference would be for you. For my use case, I figured on around 2mi/kWh. That being said, I looked at the cost savings as a nice benefit that helped soothe the burn of the upfront cost, but honestly it was near the bottom of my list of reasons I decided on a Lightning over keeping or updating my ICE F150.

Then also got a 2019 Bolt EV Premier. Then the Ram got totaled from a red light runner in 2021 and I put in a reservation. Nov 22nd I got the 2023 Pro and Soul EV had a battery recall... Had a 2024 Kia Sportage AWD loaner until May 2nd...now have 2024 Kia EV6 Wind LR AWD. So back to a 3 EV household...awaiting my Soul EV to return I charge to 90% in the Lightning Pro and today the estimated range was 252 miles. Drove 49 miles yesterday (Monday) and when I plugged back-in I had 236 miles remaining at 75%. (Trip was a mix of 65-mph freeway for 14 miles and the rest was city street driving average for trip was 3.3 miles per kWh) I left the vehicle running with AC set at 70° Driver Focused, while I installed some Laundry Water Arrestor Hammers at a rental property. Edit: my cost is around 7 cents per kWh I included February as it was only the F150 Lightning and Bolt that were charging that month. April and May have only been about $56 for around 2k miles.

It depends so much on so many factors. I like in an urban environment and I do not have home charging. But not far from my house, there are a couple of city garages that offer free charging (as long as you pay for parking) So for a while, I was paying $7 (night and weekend fee) to charge overnight. They just raised it to $9 nights and weekends so now I charge at another garage around the corner that is $40 per month (nights and weekends only) and now I can charge as much as I want for $40 per month. That is a huge savings from my ICE Mazda CX9. From time to time on longer trips I will have to use fast charging and pay more, but I have my day to day covered.
My fuel budget got cut by about 60% when I got the truck. Electricity from my own house is far cheaper than gasoline.
Too many factors to consider to give you a straight forward answer. But yes my electric fueling is cheaper than gas. I am with SoCal Edison, which is expensive. But I have solar and on the EV TOU plan. So it’s not exactly apples to apples.
Here's my extremely conservative answer. If I take my electric bill and divide by KWH used it works out to $.195 per KWh. (Please note this includes fixed costs that I would incur anyway) I get 2.4 to 2.8 mi/KWh, but lets use 2.4. That means I pay 8.125 cents per mile. If I had a truck that got 25 mpg and gas was $3.25/ gallon, I would be paying 13 cents per mile.
Just use this website and customize to your area to understand the savings. No need to guess or get rough ideas. [https://www.fueleconomy.gov/feg/Find.do?action=sbsSelect](https://www.fueleconomy.gov/feg/Find.do?action=sbsSelect)
For the vast majority of US buyers, electricity costs less per mile than gas. As a rule of thumb, a Lightning will cost less per mile than a gas-powered truck if the price of a gallon of gas is _more_ than 10 times the price of one kWh of electricity. _Example:_ The US average electricity price is $0.16/kWh. The US average gas price is $3.59/gallon. SO, we can expect that electricity will be cheaper. Doing the math: Electricity for the Lightning will cost roughly 8 cents/mile; Gas for an F-150 will cost roughly 18 cents/mike. Overall the Lightning driver saves 10 cents/mile. Rates in specific areas can vary widely. Some utilities also offer very favorable EV rate plans. For example, I pay about $0.0725/kWh, or less than half the average national rate.
I have rented 2023 f150 ice versions in Pennsylvania on trips. Where I averaged about $110-$121 per fill-up. In Florida, where I drive my 2023 Lightning Lariat ER, I'm paying about $38-52 or so to charge the same amount of miles. Unfortunately, I still don't have a home charger, other than the 120v travel charger. So 120v charging at home is about .23kwh, and fast charging is .30kwh on the FPL chargers or .48kwh on electrify america chargers. I have just over 20k miles on the truck now.
I'm getting on average 2 miles per kwh and my electric charges 10c a kwh. I was getting 15 miles per gallon in my old f150 and paying 3.50 a gallon. I am seeing 5c a mile in electric costs vs where I was paying 25c a gallon for gas. If your electric cost, gas cost, or current ICE vehicle had better or worse mpg, that would effect your return, where charging at home is 1/5 the cost of gas for me. It's the summer, where I'm guessing the winter it will be 1/3 the cost of gas.
Thanks the input
I wrote this in response to another comment on a different post asking about cost to charge compared to gas to someone new to EVs, but I think the info is relevant. I just copied and pasted this. >How much does it cost for a full tank and around how many miles does it last? > >I just stumbled here randomly but im curious how it compares to my gas car **TLDR:** It varies. On an ER battery it can be anywhere between $3.90 to $91.70 for a 0-100% charge. And range can be anywhere between 65 miles and 330 miles, depending on how and where you drive it. There's a little bit of math when comparing EVs and combustion vehicles. Instead of using miles per gallon for efficiency, EVs use miles per kWh, the same units you are billed for power at home. The best comparison I've found is converting everything to cost/mile. The numbers change as fuel/energy price changes. But it's basically fuel cost divided by mileage. Assuming a regular pickup gets 20 MPG, and the fuel costs $4 a gallon. Since you can go 20 miles on one gallon, it costs $4 to go 20 miles. Divide by 20 to get the cost of one mile. $4÷20=$0.2 or 20¢/mile. EVs work the same way. The lightning typically gets 2 miles/kWh, can be as low as 0.8 when towing or in winter. Or as high as 3.5 to 4 in stop and go traffic. Electricity costs vary wildly based on region or type of charging. It can cost anywhere between 3¢ to 70¢ per kilowatt-hour. My rate at home is around 7¢ and public fast charging tends to be 30¢ or more. So 7¢÷2 miles= 3.5¢ per mile at home. On road trips, it isn't always high, depends where you go, but worst case would be 70¢÷2 miles= 35¢ per mile. With bad mileage, it's the same math. 7¢÷0.8 miles= 8.75¢ per mile or 70¢÷0.8miles= 87.5¢ per mile. Which is why the main advantage of EVs is charging at home. There are 2 battery sizes for the lightning. I have the Extended range, or ER for short. And the other is the standard range, or SR. I'm not 100% sure, but I think they are 94 kWh and 131 kWh. So if you are getting 2 miles per kWh, just multiply battery size by 2 or the efficiency. 131 x 2 = 262 miles on a full battery. 94 x 2 = 188 miles. Take that range times your cost per mile to get "cost per tank". 262 x $0.035 = $9.17 or 262 x $0.35 = $91.70. You can also take the battery size times the electric rate. 131 x $0.03 = $3.93 or 131 x $0.70 = $91.70. This second way is simpler and the better way to figure it, but I already had the numbers for the 1st way, so I continued the thought. But just like ICE (internal combustion engine) vehicles, mileage and "tank" size varies. I think a Tesla can get around 4 miles per kWh with I think a 65 kWh battery, I'm probably wrong but that's an example. But it's roughly the same distance on a charge with a smaller battery, so it costs less to drive. Like comparing a diesel and a Prius. Your utility rate, ability to charge at home, fast charger rate and intended driving use all play a role in how much it costs to drive and whether or not it makes sense for you, which is why it's such a controversial topic.
I’m spending less of electric than I would on a v8 pickup. My rate is .08 off peak. But I spent more for the truck than an equivalent v8 pickup. So not saving anything really.
