There are many factors to consider when determining how much electricity, and therefore how much money, is needed to charge an electric car at home. The main things you will need to determine are your city’s average electric rate and how many miles you typically drive in a month. On average, though, most EVs cost about $50 to $100 to charge per month. If you only charge your car during off-peak periods, though, you may be able to spend less money on your electric bill to get a full charge.
