Quick answer
Cost per mile = electricity price ÷ (miles per kWh × charging efficiency). Charging losses of 8–12% must be included because you pay for grid energy, not battery energy.
Cost/mile = price per kWh ÷ (mi/kWh × efficiency)
How to use the EV Cost Per Mile Calculator
- 1Enter what you pay per kWh, including standing charges if you want a true figure.
- 2Enter your car's real-world miles per kWh from the trip computer.
- 3Add your annual mileage to see the yearly cost.

Frequently asked questions
What is a good mi/kWh figure?
Compact EVs manage 4.0–4.5 mi/kWh, mid-size sedans 3.3–3.8 and electric trucks or SUVs 2.0–2.5 in mixed driving.
Should I include charging losses?
Yes. AC home charging is typically 85–92% efficient, so you buy roughly 10% more energy than the battery actually stores.
