EV Cost Per Mile Calculator

See what driving an EV costs per mile in electricity. Enter the efficiency in miles per kWh and your electricity rate — add your yearly mileage for the annual cost.

How this calculator works

Cost per mile is your electricity rate divided by efficiency (miles per kWh). Multiply by annual mileage for the yearly energy bill. Home charging usually lands around 4–6 cents a mile — a fraction of what a gas car costs — though public fast charging can be several times more.

What changes the number

Home charging is far cheaper than public DC fast charging — the per-mile cost can differ 3–5×.
Cold weather and high speeds lower efficiency (mi/kWh), nudging the per-mile cost up.
Time-of-use electricity plans with cheap overnight rates can cut your cost per mile substantially.

Frequently asked questions

How does this compare to a gas car?

Usually much cheaper — an EV at 4–6 cents a mile versus 10–15 for a typical gas car. Use the EV vs Gas calculator to compare directly with your numbers.

What rate should I enter?

Your home electricity price per kWh from your bill, or your off-peak rate if you charge overnight. For public charging, enter the charger’s per-kWh price instead.

What efficiency is realistic?

Most EVs do 3–4 mi/kWh; efficient compacts do better, trucks and SUVs worse. Use the EPA figure or your trip computer’s average.
