How much does it cost to charge an EV at home?

Most EVs travel about 3–4 miles per kWh. So a car driven 1,000 miles a month uses roughly 250–330 kWh — at the US average rate (~$0.16/kWh) that's about $40–$55 a month, usually far less than the gas it replaces.

Charging cost swings a lot by state because electricity rates do. The cheapest way to drive? Charge from your own solar panels — once installed, those miles are essentially free.
