How much it costs to charge a Tesla at home, with worked examples at different electricity prices and how to find your own number.
How much does it cost to charge a Tesla at home? It comes down to two numbers: how many kilowatt-hours (kWh) you add, and what you pay per kWh. Here is the simple math, with worked examples.
The formula
Cost = kWh added × your price per kWh
Find your price per kWh on your electric bill. Include delivery charges and taxes if your utility bills them per kWh. If you're on a time-of-use plan, use the off-peak price for overnight charging.
Worked examples
Cost to add 50 kWh, and to drive 1,000 miles at an example 250 Wh per mile (250 kWh in total):
| Price per kWh | Add 50 kWh | 1,000 miles | Per mile |
|---|---|---|---|
| $0.10 | $5.00 | $25 | 2.5¢ |
| $0.15 | $7.50 | $37.50 | 3.75¢ |
| $0.20 | $10.00 | $50 | 5¢ |
| $0.30 | $15.00 | $75 | 7.5¢ |
| $0.40 | $20.00 | $100 | 10¢ |
The 250 Wh per mile figure is a round number for the math. Use your own: your car shows its average Wh per mile on the trip and energy screens.
Find your real number
- Tesla app: Charge Stats can estimate home charging cost once you choose your utility and rate plan, or enter a custom plan with time-of-use periods.
- Your bill: compare months, or use your utility's hourly usage data if it offers it.
- VoltCoach: the app keeps a running record of your charging costs alongside your trips.
Ways to pay less
- Ask your utility about time-of-use or EV rate plans, then use scheduled charging to stay in the cheap hours.
- Some energy is lost as heat while charging, so the meter records a bit more than the battery receives. The amount varies with the setup and conditions.
- Expect higher costs per mile in cold weather, when the car uses extra energy to heat the battery and cabin.
