How much does it cost to charge a Hummer EV?

A full charge for a 2025 GMC Hummer EV Pickup 2X costs about $36.63 at home, at the US average residential electricity rate of 18¢/kWh. Filling up the same car costs $25.13 in Idaho, the cheapest state, and $67.67 in California — your own rate decides it.

That full charge draws roughly 204 kWh from the wall and buys 318 miles of EPA-rated range — about $0.115 a mile.

What it costs at three real electricity rates

Your rate is the only input that really moves this number, so here is the same car at three real ones — the cheapest state, the national average, and the most expensive large mainland market.

Hawaii is higher still at 52¢ — a 4.2:1 spread from the cheapest state to the dearest. EPA figures checked September 2026; electricity rates checked August 2026.

What it costs per mile

A GMC Hummer EV costs about $0.115 a mile to charge at home at the US average electricity rate, or $11.52 per 100 miles. That is energy only — the EPA rates this car at 64 kWh per 100 miles measured at the wall socket, so charging losses are already inside the figure and should not be added again.

Per mile is the number that survives a change of car: it does not care about battery size, so it is the only fair way to line this car up against one with a much bigger or smaller pack.

What it adds to your electricity bill

Charging a GMC Hummer EV at home adds about $115 a month to your electricity bill at the US average rate, driving 12,000 miles a year. That is the yearly cost of $1,382 spread evenly across twelve months — a month with a road trip in it costs more, and a quiet one costs less.

Nothing else on the bill changes: the car draws the same kilowatt-hours whatever else is running in the house, so the increase is the charging and nothing more.

At the cheapest state rate the same driving adds $79 a month, and $213 at the most expensive — the table above has all three. If your utility offers an overnight or time-of-use rate, charging on it lands at the low end rather than the middle.

Where the numbers come from

The EPA rates this Pickup 2X at 64 kWh per 100 miles with 318 miles of combined range. Those two figures together give the energy for a full charge, which is where the 204 kWh above comes from.

We work it out that way rather than quoting a battery size on purpose. Manufacturers publish gross capacity, which includes a buffer at each end of the pack that never takes a charge, so a cost built on it overstates your bill. And the EPA measures at the wall socket rather than at the battery, so charging losses are already inside the figure — no need to add them, and adding them would count the same loss twice.

What this means for this car

The Hummer EV uses energy on a different scale from everything else here. The 2025 Pickup 2X is rated 64 kWh per 100 miles: about a third more than a Ford F-150 Lightning, half again as much as a Cybertruck, and more than two and a half times a Tesla Model Y. It reaches 318 miles only because the battery is enormous, so covering that range draws over 200 kWh from the wall. Both the cost per mile and the cost per fill are high. This page covers the 2025 model year, the latest fueleconomy.gov lists; it has no 2026 record, and none for 2022 or 2023. The 2024 versions were rated between 63 and 72. Motor count barely matters: the three-motor 3X is rated 65 with 312 miles, and the SUV 2X matches the pickup at 64 with 315 miles. Tires are what move the number. On the mud-terrain tires both body styles can be ordered with, the 2X is rated 72 kWh per 100 miles, an eighth more energy per mile, and its range falls to 282. The 3X on the same tires is rated 70 with 289 miles, a rare case of the more powerful version using less. If the truck will spend its life on pavement, the road tires are the cheaper choice every year it is driven.

How it compares

All at 18¢/kWh and 12,000 miles a year. The gas comparison is illustrative — it is not a claim about any particular car.
