EV charging costs.

In plain English

EV charging costs are the money you spend to put energy into an electric vehicle. The price is set by two things: how much electricity the car needs (measured in kilowatt-hours, or kWh) and what you pay per kWh. Charging at home on your normal electric rate is usually the cheapest option, especially overnight on plans that charge less during off-peak hours. Public fast chargers cost more per kWh and sometimes add session or per-minute fees, so the same fill-up costs more on the road than in your garage. Because electricity prices vary widely by state and even by time of day, your real cost depends on your local rate.

01Why it matters

Charging at home versus relying on public fast chargers can change your monthly fuel cost by a lot, so it is one of the biggest factors in whether an EV actually saves you money.

02The math, step by step

To estimate a home charge, multiply the kWh you add by your electricity rate. As of March 2026, the U.S. average residential electricity price was about 18.56 cents per kWh, per the EIA, though your local rate may be higher or lower. If a car uses 30 kWh to go about 100 miles, that 100 miles costs roughly 30 times 18.56 cents, or about $5.58, at the national average. Public fast charging typically runs higher per kWh and may add fees, so the same 100 miles costs more away from home. Plug in your own local rate for a closer estimate.
