How much does it cost to charge a Mustang Mach-E?

A full charge for a 2026 Ford Mustang Mach-E RWD Extended Range costs about $17.86 at home, at the US average residential electricity rate of 18¢/kWh. Filling up the same car costs $12.25 in Idaho, the cheapest state, and $32.98 in California — your own rate decides it.

That full charge draws roughly 99 kWh from the wall and buys 320 miles of EPA-rated range — about $0.056 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. Figures checked August 2026.

What it costs per mile

A Ford Mustang Mach-E costs about $0.056 a mile to charge at home at the US average electricity rate, or $5.58 per 100 miles. That is energy only — the EPA rates this car at 31 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 Ford Mustang Mach-E at home adds about $56 a month to your electricity bill at the US average rate, driving 12,000 miles a year. That is the yearly cost of $670 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 $38 a month, and $103 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 RWD Extended Range at 31 kWh per 100 miles with 320 miles of combined range. Those two figures together give the energy for a full charge, which is where the 99 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

At 31 kWh per 100 miles the Mach-E costs about 24% more per mile than a Model Y Long Range RWD, which over a typical year is a real if unspectacular difference — on the order of a tank of gas. The wider point is how far apart the Mach-E trims sit. The EPA rates the standard RWD and RWD Extended identically at 31, the AWD Extended at 32, the AWD at 34, the GT at 37 and the Rally at 40 kWh per 100 miles. A Rally therefore uses 29% more energy per mile than the car in this table, one of the widest spreads of any model line here. If running cost matters to you, the trim you pick within the Mach-E range moves the number further than choosing a Mach-E over most of its rivals.

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.
