Cost to Charge an Electric Car at Home, by State (2026)

Home-charging a typical EV costs $1,074 a year — about a third of the $3,434/year average for gas vehicles on the same basis. But the state spread is huge: Nevada at $711/year versus Hawaii at $2,637 — a 3.7x gap, driven entirely by residential electricity prices.

Charging is half the math — what does the EV cost to buy?

Fuel savings only pay off against the right purchase price. See what buyers actually paid for the EV you're considering, compare running costs in the annual fuel-cost study, or run the hybrid break-even calculator if you're weighing a middle path.

Methodology

15,000 mi/yr at the median MY2024+ EV efficiency (37.2621 kWh/100mi), home charging at each state's average residential rate. Charging losses and off-peak EV rates not included. Prices are each state's average residential rate from the EIA's Electric Power Monthly (Table 5.6.A); efficiency is the median of 1084 model-year 2024+ EVs in the EPA dataset (37.3 kWh/100 mi). Many utilities offer time-of-use EV rates below the state average, so real-world costs are often lower; public DC fast charging is typically 2–4x home rates.

Frequently asked questions

How much does it cost to charge an electric car at home?

Nationally, about $1,074 per year at 15,000 miles — using each state's average residential electricity rate (EIA) and the median efficiency of current EVs (37.3 kWh/100 miles, EPA). That works out to roughly $15 for 250 miles of range in a typical state.

Which state is cheapest to charge an EV?

Nevada, at about $711/year (12.72¢/kWh residential). The most expensive is Hawaii at $2,637/year (47.18¢/kWh) — nearly 3.7x the cheapest state.

Is charging an EV cheaper than gas?

By a wide margin at home: $1,074/year to charge vs $3,434/year for the average gas vehicle on the same EPA basis — the EV costs about 31% as much to fuel. Public DC fast charging costs 2-4x home rates, so the economics depend on charging mostly at home.

How is the annual cost calculated?

15,000 miles/year × the median current-EV efficiency (37.3 kWh per 100 miles, from 1084 MY2024+ EVs in the EPA dataset) × each state's average residential electricity price from the EIA's Electric Power Monthly (Table 5.6.A). Charging losses (~5-10%) and special off-peak EV rates are not included — many utilities offer EV plans below the average rate, so your cost can be lower.

Where does this data come from?

Two federal public-domain sources: residential electricity prices from the U.S. Energy Information Administration (EIA) and vehicle efficiency from the U.S. EPA (fueleconomy.gov). The tables may be republished with attribution to CarWhere (carwhere.com).
