How much does it cost to charge an electric car per month?

For an EV driving 1,000 miles/month at average US efficiency of 3.5 miles/kWh, you consume roughly 286 kWh/month. At the US average residential electricity rate of $0.16/kWh, that's about $46/month—roughly $550/year. Compare this to a 28 MPG gasoline car driving the same distance at $3.50/gallon, which costs about $125/month, or $1,500/year. EV charging saves the average driver $600–$1,200/year in fuel costs vs. a comparable gasoline vehicle.

How much do I save by charging at home vs. public chargers?

Home charging at the US average rate of $0.16/kWh costs about $0.046 per mile for a 3.5 mi/kWh vehicle. DC fast charger networks (Electrify America, EVgo) average $0.30–$0.50/kWh, adding up to $0.086–$0.14 per mile—2–3× more than home charging. Over 1,000 miles/month, using fast chargers exclusively instead of home charging adds $40–$95/month. A Level 2 home charger ($400–$800 installed) pays for itself in 4–12 months vs. relying on public charging.
