EV Charging Cost Calculator

Cost per charge, per mile, per month and per year — for any electric car, in any US state.

⚡ Calculate your charging cost

Works for any EV — Tesla, Hyundai, Kia, Ford, Rivian and more.

Find it on your car's spec sheet, or use a model page — e.g. Model Y 75, Ioniq 5 80, EV9 96 kWh
EPA combined figure, or range ÷ battery. Model 3: 3.85, Ioniq 6: 3.92, R1S: 2.52

How the calculator works

Full charge cost = battery size (kWh) × electricity rate ($/kWh). A 75 kWh battery at the US average home rate of $0.18 per kWh costs $13.50 to fill from empty. At a public fast charger averaging $0.48 per kWh, the same charge costs $36.00.

Cost per mile = blended rate ÷ efficiency. If you charge 80% at home ($0.18) and 20% in public ($0.48), your blended rate is $0.24 per kWh. In a car that does 3.5 miles per kWh, that is $0.069 per mile — about $69 a month for 1,000 miles.

Why your state matters. Electricity is not one national price. Washington averages $0.146 per kWh, California $0.298 — more than double. The same car and the same driving can cost $42 a month in one state and $85 in another. That is why this calculator asks for your state instead of using a single national number.

Frequently asked questions

How do you calculate EV charging cost?

Multiply the battery's usable capacity in kWh by your electricity rate in dollars per kWh. A 75 kWh battery at $0.18 per kWh costs $13.50 for a full charge. Divide by the car's efficiency in miles per kWh to get cost per mile.

What is the average cost to charge an EV at home?

About $13 to $17 for a full charge at the US average home rate of $0.18 per kWh, or roughly $50 a month for 1,000 miles of driving. Your state matters: Washington averages $0.146 per kWh and California $0.298.

Is it cheaper to charge at home or in public?

Home charging is almost always cheaper. Public DC fast charging averages about $0.48 per kWh in the US — roughly two and a half times the average home rate of $0.18 per kWh.

Estimates only. Electricity rates are statewide averages from the U.S. Energy Information Administration (August 2026). Public charging prices vary by network and location; $0.48/kWh is a national average estimate. Rates updated November 2026. Not financial advice.
