# What does it cost to charge an EV?

Enter your miles, your car's efficiency and your power rate. See the cost per mile and per month at home, at public chargers and in a gas car.

 Home charging per month

 Per mile at home

 Saved vs gas per month

 Miles per month
 Efficiency (miles per kWh)
 Battery size (kWh)
 Home rate ($ per kWh)
 Public Level 2 ($ per kWh)
 DC fast charging ($ per kWh)
 Share charged at home (%)
 Charging loss (%)
 Gas price ($ per gallon)
 Gas car MPG

The values filled in are examples. Use the rate on your power bill (total charges divided by kWh used) and the efficiency your car shows; most EVs get 3 to 4 miles per kWh, less in winter and at highway speed.

## Cost by where you charge

## How it works

Energy used is miles divided by miles per kWh. Home charging pulls more than that from the wall because some is lost as heat, so the home cost is energy × (1 + charging loss) × your rate. Public chargers bill the energy delivered to the car, so no loss is added. The mixed figure charges the share you set at home and the rest on DC fast chargers. A full charge is the battery size from 10% to 100%, which is how most people top up. Gas cost is miles ÷ MPG × gas price.

Do you need home charging? Compare the home and DC fast rows: if you can't charge at home or work, your cost per mile is the fast-charging one, which can match or beat a gas car only when power is cheap and gas is dear.
