EV Charging Cost Calculator

Estimate what home charging costs for your vehicle and driving habits, then compare it with a gas car.

Your EV and driving

Choose a vehicle, then adjust the values you know.

Home EV charging$518.47/yr
Gas vehicle (25 MPG)$1,680.00/yr
Result explanation

At 4.11 miles per kWh, your EV stores about 243 kWh for 1,000 miles. Accounting for 90% charging efficiency, it draws 270 kWh from the wall.

At $0.16 per kWh, that is $43.21 per month. The gas comparison uses 25 MPG and $3.50 per gallon.

Methodology

What the calculation includes

The estimate starts with miles driven and the selected vehicle’s efficiency. Charging loss is added before applying your electricity rate. This separates battery energy from energy billed by your utility.

Gas comparison uses the MPG and fuel price you enter. It compares energy or fuel cost only, excluding maintenance, insurance, depreciation, taxes, and charging hardware.
