Home EV Charging Cost Calculator

Estimate what charging your EV at home could add to your electricity bill based on your driving, vehicle efficiency and electricity rate.

Your inputs

Start with a few numbers from your driving and electric bill.

miles per day
kWh / 100 miles

Not sure? Many EVs fall roughly in the 25–40 kWh per 100 miles range. Check your vehicle specifications or efficiency display for a more accurate estimate.

cents / kWh

Use your actual supply and delivery rate when possible. Your bill may show a cost per kWh.

Advanced assumptions
%

Some energy is lost between the wall and the battery. Actual losses vary by vehicle, charger, temperature and charging conditions.

Your estimated home charging cost

$51.68 / month

Based on 912 miles per month.

Annual cost$620.16
Electricity use304 kWh
Cost per 100 miles$5.67
Charging loss10% included
How we calculated this
912 miles × 30 kWh / 100 miles = 273.6 kWh to the battery. With 10% charging loss, that is about 304 kWh from the wall.
