Using these prices for EV charging
EIA's figure is an average: total residential revenue divided by kWh sold. It is a good starting point, but your own marginal rate is what matters for charging. If your utility offers a time-of-use or EV rate, overnight electricity is often far cheaper than the average shown here.
Plug your own rate and car into the EV charging cost calculator, or see Tesla-specific numbers in how much it costs to charge a Tesla.
Questions drivers ask
What is the average cost of electricity per kWh in the U.S.?
18.31¢ per kWh for residential customers in July 2026, according to the U.S. Energy Information Administration (Electric Power Monthly, Table 5.6.A).
Which states have the cheapest electricity?
In July 2026, the lowest average residential prices were in Louisiana, Nevada, Utah. The highest were in Hawaii, California, Maine.
Why is my bill’s rate different?
EIA averages divide total revenue by total kWh sold, so they include fixed charges, taxes and every rate plan. Your marginal rate for an extra kWh (the one that matters for EV charging) can be higher or lower, especially on tiered or time-of-use plans.
How much does it cost to charge an EV at these prices?
Multiply your EV’s EPA kWh per 100 miles by the price. A car using 30 kWh/100 mi at the national average costs about 5.5¢ per mile.
