What a full EV charge costs in every US state (2026)

Charging an EV at home is cheaper than gas almost everywhere in the US. How much cheaper depends a lot more on your state than on your car.

I put together the numbers for every state using June 2026 residential electricity prices (U.S. EIA) and late-September gas prices (AAA state averages).

Assumptions: an EV using 30 kWh per 100 miles, plus 10% charging losses; a gas car doing 28 mpg; 12,000 miles a year. A "full charge" means 75 kWh, about a typical mid-size EV battery.

The cheapest and most expensive states for a full charge

State	Electricity	Full charge (75 kWh)
Nevada	13.11¢/kWh	$10.82
Nebraska	13.25¢/kWh	$10.93
Utah	13.37¢/kWh	$11.03
Louisiana	13.49¢/kWh	$11.13
Tennessee	14.07¢/kWh	$11.61
…
New York	29.49¢/kWh	$24.33
Maine	29.59¢/kWh	$24.41
Massachusetts	29.61¢/kWh	$24.43
California	34.74¢/kWh	$28.66
Hawaii	52.72¢/kWh	$43.49

That's a 4x spread for the same battery. The same 300 miles is about $11 in Nevada and $43 in Hawaii.

What you actually save vs gas, per year (12,000 miles)

State	EV / year	Gas car / year	You save
Nevada	$516	$2,352	$1,836
Washington	$588	$2,364	$1,776
Utah	$528	$2,136	$1,608
Idaho	$564	$2,136	$1,572
Oregon	$648	$2,172	$1,524
California	$1,380	$2,736	$1,356
Texas	$636	$1,668	$1,032
New York	$1,164	$1,920	$756
Massachusetts	$1,176	$1,884	$708
Hawaii	$2,088	$2,400	$312

Three things that stand out

California has the second-priciest electricity, but still saves well above Texas. Gas there is $6.38/gal, so the EV comes out about $1,356 a year ahead. Texas has cheap power, but gas is $3.90, so the gap is smaller.
The West wins. Nevada, Washington, Utah, Idaho and Oregon have cheap electricity and expensive gas, the best combo for an EV.
New England and Hawaii save the least. Expensive electricity eats most of the gain. Hawaii still saves money, just not much.

Ways to beat these numbers

Time-of-use rates. Many utilities sell overnight power for a fraction of the daytime price. Charging after midnight can cut the costs above by a third or more.
Avoid fast chargers for daily driving. DC fast charging often costs 2 to 4 times home rates.
Your efficiency matters. A big SUV EV at 40 kWh/100 mi costs about a third more per mile than the 30 kWh/100 mi used here. Winter adds more.
