How much does it cost to charge an electric car?

It depends mainly on your electricity rate and how efficiently the vehicle uses energy. To estimate home charging cost, multiply the kilowatt-hours used by your price per kWh from your utility bill, and add a little for charging losses. Many utilities offer cheaper off-peak or EV rates. Public charging, especially DC fast charging, usually costs more per mile than home charging and pricing varies by network.
