How much does it cost to charge a Tesla Model X?

A full charge for a 2026 Tesla Model X All-Wheel Drive costs about $20.28 at home, at the US average residential electricity rate of 18¢/kWh. Filling up the same car costs $13.91 in Idaho, the cheapest state, and $37.45 in California — your own rate decides it.

That full charge draws roughly 113 kWh from the wall and buys 352 miles of EPA-rated range — about $0.058 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 Tesla Model X costs about $0.058 a mile to charge at home at the US average electricity rate, or $5.76 per 100 miles. That is energy only — the EPA rates this car at 32 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 Tesla Model X at home adds about $58 a month to your electricity bill at the US average rate, driving 12,000 miles a year. That is the yearly cost of $691 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 $40 a month, and $106 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 All-Wheel Drive at 32 kWh per 100 miles with 352 miles of combined range. Those two figures together give the energy for a full charge, which is where the 113 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 Model X costs about a fifth more per mile to charge than its Model S sibling: 32 kWh per 100 miles against 27, the price of a taller, heavier body with a third row. Against other three-row SUVs it looks far better. A Rivian R1S is rated 40, so the Model X covers the same distance on a fifth less energy, and it even edges the much smaller Honda Prologue, rated 33. The 2026 update matters for anyone comparing model years. The 2025 dual-motor car was rated 34 kWh per 100 miles with 329 miles of range; the 2026 car is 32 with 352 miles, so the newer version uses about 6% less energy per mile and goes further on a charge. The Plaid adds less than you might expect, at 34 kWh per 100 miles and 335 miles for 2026. On the 2025 Plaid, wheels were the bigger lever: 36 on 20-inch wheels and 38 on 22-inch. Older cars sit higher still, and the 2016 versions were rated 36 to 39 depending on battery and motors.

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.
