- At the 2024 national average residential rate of 16.5 cents per kWh, an EV with the median model year 2024 rating (38.4 kWh per 100 miles) costs $0.063 per mile to charge at home.
- State electricity rates create a 3.7x range: from about $0.044 per mile in North Dakota to $0.165 in Hawaii.
- Against a 27.2 MPG gasoline car at 2025 average state prices, home-charged EVs cost between 3% more and 70% less per mile in the nine states with tracked EIA gasoline prices.
01 How EV Charging Cost Works
The cost to charge an EV at home depends on two things: your local electricity rate (cents per kilowatt-hour) and your vehicle's efficiency. The EPA rates each EV's energy use in kWh per 100 miles. For the 266 all-electric model year 2024 configurations in the Fuel Economy Guide, the median is 38.4 kWh per 100 miles, or 2.60 miles per kWh; individual vehicles differ.
EPA/DOE Fuel Economy Guide (vehicles.csv), model year 2024 all-electric configurations, median combined kWh per 100 miles (combE)For example, at the national average residential rate of 16.5 cents per kWh, an EV averaging 2.60 mi/kWh costs about $0.165 / 2.60 = $0.063 per mile. A 30 MPG gas car at $3.10 per gallon costs $0.103 per mile, so the EV costs about 39% less per mile at these inputs.
EIA-861 Table 5A (2024): U.S. average residential price 16.48 cents/kWh; efficiency from the EPA/DOE Fuel Economy Guide. The gasoline comparison is an illustrative 30 MPG car at $3.10 per gallon (the 2025 average).02 All 50 States Ranked by EV Charging Cost
Residential electricity rates range from 11.5 cents per kWh in North Dakota to 42.9 cents in Hawaii. The table ranks the 50 states plus DC by EV cost per mile, using each state's average residential electricity rate and the median efficiency of 2.60 mi/kWh.

03 EV vs Gasoline: Cost per Mile
The table compares the cost per mile of a home-charged EV with a gas car averaging 27.2 MPG, the EPA figure for the model year 2024 average new vehicle, in the nine states where the EIA publishes weekly state-level gasoline prices, using each state's 2025 average.

For a driver covering 12,000 miles per year, the annual fueling cost difference between a home-charged EV and a 27.2 MPG gas car varies by state:
Calculated: 12,000 miles × cost per mile. EV uses the state residential rate and 2.60 mi/kWh; gas uses the state's 2025 mean gasoline price and 27.2 MPG| State | EV Annual Cost | Gas Annual Cost | Annual Savings |
|---|---|---|---|
| Washington | $548 | $1,823 | $1,275 |
| Florida | $651 | $1,304 | $653 |
| Colorado | $687 | $1,265 | $578 |
| Minnesota | $712 | $1,307 | $595 |
| U.S. Average | $759 | $1,366 | $607 |
| Ohio | $736 | $1,306 | $569 |
| Texas | $688 | $1,174 | $485 |
| California | $1,473 | $1,945 | $473 |
| New York | $1,126 | $1,348 | $223 |
| Massachusetts | $1,352 | $1,310 | −$42 |
Annual savings in these nine states range from about −$42 to $1,275. Over five years, that accumulates to −$210 to $6,373, assuming prices stay the same. A negative figure means the gas car costs less to fuel.
