EV home charging cost: per mile, per month, per state
The cost of charging an electric car at home, from its EPA efficiency rating, the miles you drive and your state's average electricity price.
Short answer
Multiply the miles you drive by your car's EPA rating in kWh per 100 miles, then by your electricity price. At 30 kWh per 100 miles, 1,000 miles of home charging take 300 kWh: $54.93 at the US average residential price for July 2026, about 5.5 cents a mile. The same miles cost $38.16 in Louisiana and $144.00 in Hawaii. The EPA rating already includes the energy lost while charging.

Cost per 1,000 miles in each state
Three efficiency levels: 24 kWh per 100 miles, the 2026 Tesla Model 3 Standard RWD's rating; 30, the 2026 Hyundai Ioniq 5 RWD's; and 40, for vehicles that use more than any model in the table further down. A thousand miles a month is 12,000 a year.

How the calculation works
kWh = miles × kWh per 100 miles ÷ 100
cost ($) = kWh × price (¢ per kWh) ÷ 100
Worked example: 1,000 miles at 30 kWh per 100 miles takes 300 kWh. At the US average of 18.31 cents that's $54.93, or 5.5 cents a mile. At the EPA label's assumption of 15,000 miles a year, the same car uses 4,500 kWh, which costs $823.95 a year at the US average. In Hawaii, at 48.00 cents, 1,000 miles cost $144.00; in Louisiana, at 12.72 cents, $38.16.
Why the EPA figure already includes charging losses
The number to use is the EPA's kWh per 100 miles, printed on the window sticker and listed at fueleconomy.gov. The EPA and Department of Energy site says the label value “tells you how many kilowatt-hours the vehicle would use to travel 100 miles”. Its FAQ adds that electricity use is measured from the charge source, not the battery, because “a small amount of energy is lost in charging the vehicle” and the figure “represents the energy that is paid for by the consumer”. So the kWh it gives is what your meter counts, and there's no need to add a charging loss on top.
The window sticker also shows a yearly fuel cost. That figure, the site explains, assumes 15,000 miles a year and an electricity price projected by the US Energy Information Administration for the model year. The calculator lets you replace both with your own miles and your state's price, or the rate on your bill.
What some 2026 models are rated at
| 2026 model | kWh per 100 miles | 1,000 miles at home |
|---|---|---|
| Tesla Model 3 Standard RWD | 24 | $43.94 |
| Tesla Model Y Long Range RWD | 25 | $45.78 |
| Tesla Model Y Long Range AWD | 27 | $49.44 |
| Nissan LEAF 75kWh (18-inch steel wheels) | 28 | $51.27 |
| Hyundai Ioniq 5 RWD | 30 | $54.93 |
| Tesla Model Y Performance AWD | 32 | $58.59 |
| Hyundai Ioniq 5 AWD XRT | 36 | $65.92 |
The spread inside one model line can be wide. Fueleconomy.gov lists the 2026 Tesla Model Y from 24 kWh per 100 miles for the Standard RWD on 18-inch wheels to 32 for the Performance AWD, and the 2026 Ioniq 5 from 29 for the standard-range car to 36 for the AWD XRT. Look up your exact version, wheel size included, at fueleconomy.gov before you rely on a number.
What the calculator leaves out
- Public charging. Fast chargers set their own prices, which are not in EIA's residential figures. Set the share charged at home below 100% to count only the home part.
- Special rates. If your utility bills a different price for overnight or EV charging, type that rate into the price box.
- Weather and driving style. The EPA figure is a test result, not a measurement of your driving. If your car's trip computer shows energy use per mile, a few weeks of your own figures will be a better guide.
What the state price is
The prices are the residential averages in the US Energy Information Administration's Electric Power Monthly, Table 5.6.A, for July 2026, marked as preliminary. EIA's next release is due on October 23, 2026.
