Most cars still cost more to charge than to fill up with gas

• A big part of the electric car transition is cost parity with gas-powered vehicles.
• While charging and fueling trucks costs the same, other cars and their electric counterparts differ.

It's not yet cheaper to charge many electric cars than it would be to fuel their gas-powered counterparts up with gas, a new study found.

The cost of filling up at a gas station versus plugging in — and whether or not those two match up — largely depends on the segment and price, according to a study from Anderson Economic Group, published Tuesday.

Trucks cost about the same to fuel and charge, while entry- and mid-level cars and SUVs cost more to charge at home and in public than they do to fuel at a gas station, the group found. Luxury cars and SUVs fall somewhere in the middle.

The study is based on the latest information on gas and residential electricity prices, commercial charging prices, tax rates on fuel and electric cars, fuel economy details, and more to compare the cost of fueling versus charging for 100 miles of driving.

Last year, skyrocketing gas prices turned many consumers onto the idea of electricity. As gas prices normalize, there is less incentive for some people to make the switch.

Cost parity between electric vehicles and internal-combustion engine cars is largely lacking; that is, EVs are generally more expensive (with an average transaction price of $53,438 in June, per Kelley Blue Book) than gas ones (averaging $48,808).

Reaching cost parity is going to be a crucial part of boosting EV adoption, and it is improving — but that's not the end of the story. How much it costs to fuel versus charge vehicles is something consumers are taking into consideration, too.

Here's how the costs break down by segment:

Trucks

For trucks, it roughly costs the same to fuel and charge. Whether you're fueling a Ford F Series, Ram 1500, or Chevrolet Silverado, it costs about $17.58 for every 100 miles. Trucks that take diesel also cost around $17.10 to fuel for the same mileage. If you have a Rivian R1T or GMC Hummer, the cost to charge at home isn't much different; it's around $17.72 per 100 miles.

The cost to charge, however, skyrockets 48% to $26.38 if a driver is mostly charging in public.

Entry-level cars and SUVs

Maybe a driver owns a Nissan Versa, Hyundai Elantra, or Kia Forte. It'll cost them $9.78 in gas for every 100 miles.

But switch to a Nissan Leaf or Chevrolet Bolt, and that increases to $12.55 in home charging expenses. Head to a commercial charger, and a driver is looking at nearly $16 — 64% more than if you stuck with a gas-powered car in the same segment.

Luxury cars and SUVs

The luxury segment is interesting in that it actually might cost less to own electric — so long as you plug in at home.

It costs $17.56 for every 100 miles for a gas-powered Lexus ES, Porsche Macan, Mercedes-Benz GLE, or similar vehicle.

The Porsche Taycan, Tesla Model X and Model S, and Mercedes-Benz EQS might cost around $13.50 if you're juicing up in your garage, saving you about 23%.

But if you drive one of these EVs and you mostly use public charging, you're back to square one, paying around $17.81 per 100 miles.

Mid-level cars and SUVs

For now, drivers will likely pay more to charge their Ford Mustang Mach-E, Kia EV6, or Volkswagen ID.4 than to fuel their internal-combustion engine counterparts like the Chevrolet Equinox, Nissan Altima, or Subaru Outback.

Charging any of these vehicles at home will run about $12.62 per 100 miles, while fueling one at a gas station might run $11.08. That difference, while not incredibly substantial, might add up — and when these drivers go to a public charging station, they're likely to pay $16.10 per 100 miles.
