Electric Vehicle Charger cost vs U.S. average
At the state average rate, an electric vehicle charger in Maryland costs $15.12 more a month than it would at the U.S. average rate.
How much electricity does an electric vehicle charger use?
An electric vehicle charger draws roughly 1,400-7,600 W; we use 7,200 watts running 2 hours/day. That comes to 14.4 kWh a day — 432.0 kWh a month, or 5256.0 kWh over a year — using kWh = watts × hours ÷ 1000. For the wattage range, amps, and how that math works, see how many watts an electric vehicle charger uses.
EV charging cost depends on vehicle efficiency and miles driven, but the underlying electricity rate remains the main lever for charging cost by state. Maryland prices that energy at 21.84 ¢/kWh, against a 18.34 ¢/kWh national average.
Electric Vehicle Charger operating cost estimate in Maryland
| Time period | Energy use | Cost |
|---|---|---|
| Per hour | 7.20 kWh | $1.57 |
| Per day | 14.4 kWh | $3.14 |
| Per month | 432.0 kWh | $94.35 |
| Per year | 5256.0 kWh | $1147.91 |
These figures use the all-in average rate. Your actual bill can run higher when separately billed taxes, seasonal pricing, and fixed monthly fees apply.

What changes the cost the most?
Two things move this number: your state's rate, which you can't change, and how hard the appliance works, which you often can. For an electric vehicle charger, that mostly comes down to charger level, miles driven, charging schedule.

Source & Method
Source: U.S. Energy Information Administration (EIA) Retail Sales of Electricity. Updated: June 2026. Estimates use the EIA all-in average residential rate — energy, delivery, fixed charges, and utility fees together, not just the electricity itself. Fees are inside the rate, not an extra on top; how your own bill splits fixed versus per-kWh charges varies by utility. For what's inside the all-in rate, see hidden electricity fees; for how rates and estimates are defined, see the methodology hub.
