Photo: VolvoUpdated November 2026The question every new EV owner asks: how much will it add to my electric bill? The answer depends almost entirely on where you live. Home electricity costs about 12 cents per kilowatt-hour in the cheapest states and more than 45 cents in Hawaii. Gas prices swing a lot too. So we ran the numbers for every state.
The short version: a typical electric SUV costs about $5.46 to drive 100 miles on home electricity at the national average price, against about $14.32 for a 28-mpg gas car. Even in the most expensive state for electricity, charging at home still comes out ahead!

What the numbers tell us
The cheapest places to charge are in the middle of the country. North Dakota, Nebraska, Idaho and Utah all come in under $4 per 100 miles, where electricity has long been inexpensive. At the other end, New England, New York, California and Hawaii pay the most, with Hawaii at about $13.92 per 100 miles.
Savings are a different story, because they depend on gas prices too. Nevada comes out on top: cheap electricity and some of the most expensive gas in the country add up to about $14.08 saved every 100 miles. The West Coast does well for the same reason. California has expensive electricity, but its gas is so expensive that a driver there still saves more than $10 every 100 miles.
Ways to pay even less
Ask for a time-of-use plan. Many utilities sell overnight electricity for much less than the average price. Since most EVs sit in the driveway all night, scheduling your charging for off-peak hours can cut these numbers substantially. Your utility's website will list its EV or time-of-use rates.
Look for utility rebates. Plenty of utilities still offer money toward a home charger or its installation, or a special EV rate. It is worth checking before you buy a charger.
Public fast charging costs more. These figures are for charging at home. DC fast chargers on road trips usually charge several times the home rate, so if you can't charge at home, your costs will be closer to a gas car's. Our Supercharger Tracker shows which cars can use Tesla's network.
