EV Charging Cost Calculator

See your home charging cost per mile, and how it stacks up against an equivalent gas vehicle.

This covers charging cost per mile only. Want total annual savings including reduced maintenance too? See the EV Savings Calculator.

This tool provides a planning estimate based on the assumptions shown below the results — it is not a quote, and actual costs and savings will vary by installer, local rates, and your specific home.

Your state

Sets the home charging rate below to your state's average (EIA, April 2026) — edit it if you know your actual rate.

Miles driven per month

Vehicle efficiency (kWh per 100 miles)

Check your EV's window sticker or manufacturer spec — most fall between 25–40.

Home electricity rate (per kWh)

Compare against a gas vehicle

Gas vehicle MPGGas price ($/gallon)

Enter your driving habits to see your charging cost.

How this calculator works

Monthly energy need is your miles driven divided by 100, multiplied by your vehicle's kWh-per-100-miles efficiency, then priced at your home electricity rate.

The gas comparison converts the same distance into gallons needed at your comparison vehicle's MPG, priced at your local gas price.
