Cost to charge an EV at home, by state

$4.46 to $15.35to charge 100 miles at home, lowest to highest cost

Charging a typical EV (38 kWh per 100 miles) for 100 miles at home costs $4.46 in North Dakota and $15.35 in Hawaii. A 23 mpg gasoline car costs between $16.70 and $26.91 for the same distance at EIA's 28 Sep 2026 prices (U.S. average $4.46). Home charging is the cheaper fuel in 51 of 51 states and the state grid emits less per mile than the gasoline car in 51 of the 51 states with eGRID data.

kWh per 100 miles: EPA combined rating of battery electric models 2024 to 2026, 10th percentile, median and 90th percentile (includes charging losses).
Electricity price: EIA 2025 average for all home customers, not a time-of-use plan price.

Questions

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

About $5.81 per 100 miles in the median state for a typical EV, from $4.46 in North Dakota to $15.35 in Hawaii.

Which state is cheapest for charging an EV?

North Dakota, at 11.81 cents per kWh.

Which state is the most expensive?

Hawaii, at 40.59 cents per kWh.

Is charging cheaper than gasoline everywhere?

On these inputs in 51 of 51 states. The break-even price is on each state page.

What range of kWh per 100 miles do EVs use?

EPA ratings for 913 models of 2024 to 2026 run from about 29 to 47 (10th to 90th percentile), median 38.

How much carbon does an EV save?

It depends on the grid: in 51 of 51 states the state grid emits less CO2 per mile than a 23 mpg gasoline car at 8.887 kg per gallon.

Do time-of-use rates make charging cheaper?

Often, but plan prices are not in our data. Each state page gives the share of utilities with a residential time-of-use rate (EIA-861).

Where does the gasoline price come from?

EIA weekly regular retail gasoline, week of 28 Sep 2026; nine states have their own series and the rest use a PADD region average.

Can I use my own numbers?

Yes: the calculator takes miles, kWh per 100 miles, both prices and the gasoline car's mpg.

Which state has the most public EV chargers per resident?

Vermont with 84 stations per 100,000 residents; Louisiana has 6 (AFDC, 2 Oct 2026).

How many public charging stations are there in the United States?

82,510 open to the public in the 51 states on 2 Oct 2026, 15,702 with a DC fast port (AFDC).

Where does the registration count come from?

AFDC vehicle registration counts by state, derived by NLR from Experian data and rounded to 100; see each state page for 2021 to 2025.
