How much does it cost to charge an electric car at home?
The cost of a charge is the kilowatt hours that leave the wall times your rate. This page uses each state's average residential electricity price for August 2026 and lets you set the battery, the charge window, the losses and your real rate.
Charging a 75 kWh battery from 20% to 80% at home costs about $9.08 at the US average of 18.16 cents per kWh, and driving costs about $6.73 per 100 miles at 3 miles per kWh. In Nevada the same charge is $6.36, in Hawaii $23.59.
At 18.16 cents per kWh (US average), 370 kWh a month for 1000 miles.
Gasoline comparison at 30 mpg and 3.20 dollars a gallon: 10.7 cents a mile, 10.67 dollars per 100 miles. Change the figures above to compare with your own car.

What drives the cost
Three things: the rate, the car's efficiency and the losses. The rate varies three to one across states and more than that between an overnight EV tariff and a highway fast charger. Efficiency runs from about 2.3 miles per kWh for a large pickup to over 4 for a small sedan, and it falls in cold weather and at highway speed. Losses are 8 to 12% on a Level 2 charger and higher on a wall socket, because the on-board charger runs longer at low power.
Home against public charging
Home charging at the average rate costs $6.73 per 100 miles in this example. A DC fast charger at 50 cents per kWh costs $18.52 for the same distance, close to the gasoline figure. Most owners do the large majority of their charging at home and use fast chargers for trips, so the home rate decides the annual cost.
Questions people ask
How much does it cost to charge an electric car at home?
A 75 kWh battery charged from 20% to 80% takes about 50 kWh from the wall once charging losses are included, which is about $9.08 at the US average of 18.16 cents per kWh. In Nevada it is about $6.36, in Hawaii about $23.59.
What does an EV cost per mile?
At 3 miles per kWh and a 10% charging loss, about 6.7 cents a mile at the US average rate, or $6.73 per 100 miles. A gasoline car at 30 miles per gallon and 3.20 dollars a gallon is about 10.7 cents a mile.
Why add a charging loss?
Some energy is lost as heat in the charger, the cable and the battery. Level 2 home charging typically loses 8 to 12%, Level 1 (a wall socket) more. You pay for the kilowatt hours that leave the wall, not the ones that reach the battery.
Is public fast charging more expensive?
Usually two to three times the home rate, 40 to 60 cents per kWh is common, and some networks bill by the minute. The calculator takes any rate, so type the network's price to compare.
Does a time-of-use rate change the answer?
A lot. Many utilities offer overnight EV rates well below the average in the table. Enter the overnight rate if you charge on a schedule.
