How much will charging an EV increase my electric bill?

Your electric bill will rise by the amount of energy you use to charge at home, multiplied by your utility’s electricity rate. A simple estimate is: monthly miles driven divided by the EV’s miles per kWh, then multiplied by your price per kWh. Real billing can be slightly higher because charging is not 100 percent efficient.

For example, 1,000 miles per month in an EV averaging 3.3 miles per kWh uses about 303 kWh at the battery. At the U.S. residential average of 18.44 cents per kWh in May 2026, that is about $56 before charging losses. Your actual cost can be much higher or lower, and time-of-use or EV-specific utility rates can make overnight charging cheaper.
