What does it cost to charge an EV in Maryland?
At Maryland’s average electricity rate of 20.6¢/kWh, a typical driver (13,500 mi/yr, mostly home charging) spends about $1,011 a year — roughly 7.5¢ per mile, and around $639 less than the same miles in a 27 MPG gas car. Run your own numbers below.

Why Maryland charging costs what it does
Maryland homes pay about 20.6¢/kWh, which is 2.2¢ above the US average. Because home electricity is the main driver of EV running cost, that puts Maryland drivers toward the pricier end for charging. Charging more at home (versus public fast-charging at $0.40–0.50/kWh) lowers it further.

Cut it further with solar
If you charge at home, your EV runs on whatever your roof or the grid supplies. Pairing an EV with rooftop solar can drop your effective charging cost well below the grid rate — see whether that maths works where you live with our Maryland solar payback calculator.
