Electric car running cost
Efficiency is wall-to-wheel, so charging losses are already in the kWh figure. The public price and the gas price are examples. Replace them with the prices where you charge and fill up.

Tesla Model S charging cost by trim
| Trim | kWh per 100 mi | EPA range | Cents per mile | 1,000 miles | 240 V charge |
|---|---|---|---|---|---|
| Model S | 27.1 | 410 mi | 4.7 | $47 | 9.7 h |
Source: U.S. EPA and DOE, fueleconomy.gov, model year 2026, checked October 10, 2026. The highlighted trim is the one used for the headline figures. Prices: 17.23 cents per kWh, the 2025 US residential average from EIA Form EIA-861.
About the Tesla Model S and its energy use
The Model S is a full-size sedan, and it has the longest EPA range of any vehicle on this site, 410 miles in the 2026 data. It also uses less electricity per mile than the larger Model X, at about 27.1 kWh per 100 miles.
A long range means a large battery, and EPA lists about 9.7 hours to charge from empty on a 240 volt connection. Most owners top up at home overnight instead, so the daily cost follows the miles driven and your price per kWh.
What it costs in other states

| North Dakota | 11.82 | 3.2 | $32 |
| Idaho | 11.83 | 3.2 | $32 |
| Nebraska | 12.05 | 3.3 | $33 |

If you use public fast chargers
Public fast charging prices are set by each network and change with the place and the time. Check the price on the charger or in the app. This table shows what the Tesla Model S would cost per mile at four example prices, compared with charging at home at the US average.
| Price per kWh | Cents per mile | 1,000 miles | Versus home at US average |
|---|---|---|---|
| $0.30 | 8.1 | $81 | 1.7 times |
| $0.45 | 12.2 | $122 | 2.6 times |
| $0.60 | 16.3 | $163 | 3.5 times |
| $0.75 | 20.3 | $203 | 4.4 times |

Break-even gas price
| Where you charge | 25 mpg car | 30 mpg car | 35 mpg car | 40 mpg car |
|---|---|---|---|---|
| North Dakota price | $0.80 a gallon | $0.96 a gallon | $1.12 a gallon | $1.28 a gallon |
| US average price | $1.17 a gallon | $1.40 a gallon | $1.64 a gallon | $1.87 a gallon |
| Hawaii price | $2.74 a gallon | $3.29 a gallon | $3.84 a gallon | $4.38 a gallon |
If gas where you live costs more than the figure in the table, charging at home costs less per mile than driving a gas car with that fuel economy. If gas costs less, the gas car is cheaper per mile on fuel alone.
How we calculate it
Cost per mile is the EPA kWh per 100 miles, divided by 100, times the price per kWh. EPA measures efficiency at the wall, so charging losses are already inside the figure. Real efficiency changes with speed, temperature, tires and load, so use the EV charging cost calculator with your own numbers.
