Cost to Charge an EV at Home by State in 2026: per 100 Miles and per Year at EIA Rates

How the tables are computed

Three inputs, all public. The electricity rate is EIA's average residential price by state for June 2026 (Electric Power Monthly, Table 5.6.A), the same data that feeds the EV savings calculator. Vehicle efficiency is the EPA combined rating in kWh per 100 miles from fueleconomy.gov; the three tiers below bracket almost every EV on sale:

The third input is charging efficiency. The EPA figure is energy delivered to the battery; the meter counts energy drawn from the wall. Level 2 AC charging typically loses around 10% in the onboard charger and cabling, so the "wall" annual cost column below multiplies by 1.10. Treat that as a planning assumption, not a measurement of your car.

Annual cost for 12,000 miles: cheapest and most expensive states

The "at the wall" column includes the 10% Level 2 charging-loss allowance. The last column is the gasoline price at which a 30 MPG car would cost the same per mile as the 30 kWh/100 mi EV; if pump prices in your state are above it, the EV is cheaper to fuel.

Note what the break-even column says about Hawaii and California: at the average retail rate an EV there is only cheaper than a 30 MPG gas car when gasoline is above $4.74 and $3.13 per gallon respectively. Those are exactly the states where the utility's EV time-of-use plan, not the average rate, decides the economics.

Why the average rate overstates your cost in high-rate states

EIA's figure is total residential revenue divided by total residential kWh, an average across every plan and hour. EV owners mostly charge overnight, and many utilities in the expensive states sell overnight electricity on time-of-use or EV-specific tariffs at a fraction of the peak price. The right way to use the tables above is as a ceiling: if your utility offers an off-peak rate, plug that rate into the EV charging cost calculator instead. The time-of-use guide explains how those plans are structured and when they backfire (households that cannot shift laundry and cooking off-peak).

The reverse caution applies in the cheap states. Nevada's 13.11¢ is an average of flat tariffs; there is little room for an EV plan to improve on it, so the table value is close to what you will pay. Fixed monthly charges are outside both cases; they do not change with charging.

Public charging changes the math

Every number on this page is for home charging on a residential meter. DC fast charging is priced per kWh or per minute by the network, includes demand and session costs the residential rate does not, and in most markets lands well above even the most expensive state's residential average. A driver who fast-charges for half of their miles will not see the state ranking above; they will see the network's ranking. The home vs public charging comparison and the state-by-state public and DC fast charging FAQ cover that split, and the charging levels guide explains why Level 2 at home is the cost floor.

Putting charging cost in the total ownership picture

Fuel is one line. Whether an EV is worth it in 2026 also turns on purchase price without the federal credit (see what remains of EV incentives), insurance, tires and eventual battery replacement. What this page settles is the size of the fuel lever in your state: over 10 years and 120,000 miles, the gap between charging a 30 kWh/100 mi EV in Nevada ($4,720) and in Hawaii ($18,979) is larger than the price difference between many trim levels.
