How much does it cost to charge an EV at home?

The cost of charging is the price of electricity times the energy the car uses. EPA measures that energy at the wall, so its kWh per 100 miles figure already includes what is lost as heat while charging. Every cost on this page is that figure multiplied by a rate, for 80 models and every state.

Cost by model

At the U.S. average residential rate of 18.19¢ per kWh. Cheapest to run first. A month is 37 miles a day, about 1,125 miles.

For the newest model year of each. A range covers that model's trims: a heavier or more powerful trim uses more energy per mile. Full charge is from empty to the EPA range.

The spread is wide. The Hyundai Ioniq Electric costs 4.6¢ a mile and the GMC Hummer EV 11.6 to 13.0¢, on the same electricity. Size, weight and shape account for most of it. Battery size changes what a full charge costs but not the cost per mile.

Cost by state

For the typical EV, which uses 35.1 kWh per 100 miles, driven 37 miles a day. Cheapest first.

Average residential price for January to July 2026, from the U.S. Energy Information Administration (Electric Power Monthly, table 5.6.B). The average is total residential revenue divided by electricity sold, so delivery and fixed charges are folded in. The U.S. average is 18.19¢.

Working out your own cost

Take the price per kWh from your electric bill and your car's kWh per 100 miles from the table above. Multiply them and divide by 100, and the answer is the cost per mile, in cents if the price was in cents. For a 2027 Chevrolet Bolt at 18.19¢, that is 28.2 times 18.19, divided by 100: 5.1¢ a mile. Multiply by the miles you drive in a month for a monthly figure.

If your utility charges different prices at different hours, use the price for the hours you actually charge. That is usually the cheapest one.

Ways to pay less

• A time-of-use or EV rate. Many utilities price overnight electricity well below the daytime rate, and some have a plan written for EV owners. On a flat rate, when you charge makes no difference.
• A schedule. Once the cheap hours are known, the car's app or the charger's can hold charging until they start. Most current EVs and smart chargers can do this.
• Utility rebates. Some utilities pay toward a charger, or credit owners who let them pause charging at peak times. The qualifying list is often short, so check it before buying.
• Less energy per mile. Cold weather, high speed and heavy wheels all raise the kWh per 100 miles, and the cost with it.

Chargers that can follow an off-peak schedule

Match the size to what your car accepts. Your car's page says what that is.

Common questions

How much does it cost to fully charge an EV at home?

About $19 for the typical EV at the U.S. average rate. Across the 80 models here it runs from $5 for the Honda Clarity EV to $37 for the GMC Sierra EV. That includes the energy lost while charging. Few charges start from empty, so most nights cost far less.

How much does an EV add to the electric bill?

About $72 a month for the typical EV driven 37 miles a day at the U.S. average rate. The same driving costs about $49 a month in North Dakota and $183 in Hawaii.

Is charging an EV at home cheaper than gas?

At the U.S. average rate, by a wide margin. The typical EV costs about 6.4¢ a mile. A 30 mpg gas car costs the same only with gas at $1.92 a gallon. At Hawaii's rate of 46.28¢, the highest in the country, the matching gas price is $4.87.

Is it cheaper to charge an EV at night?

Only if your utility charges less at night. On a flat rate every hour costs the same. Many utilities offer a time-of-use or EV plan with a lower off-peak price, and a car or charger with a schedule will start at the cheap hour by itself.

Does charging on a 120 V outlet cost more than Level 2?

Very slightly. The price per kWh is the same from either outlet, but at 120 V the car's electronics stay awake for more hours to take in the same charge, so a little more energy is lost along the way.
