How much does it cost to charge a Kia Niro EV?

A full charge for a 2025–2026 Kia Niro EV FWD costs about $13.66 at home, at the US average residential electricity rate of 18¢/kWh. Filling up the same car costs $9.37 in Idaho, the cheapest state, and $25.24 in California — your own rate decides it.

That full charge draws roughly 76 kWh from the wall and buys 253 miles of EPA-rated range — about $0.054 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 Kia Niro EV costs about $0.054 a mile to charge at home at the US average electricity rate, or $5.40 per 100 miles. That is energy only — the EPA rates this car at 30 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 Kia Niro EV at home adds about $54 a month to your electricity bill at the US average rate, driving 12,000 miles a year. That is the yearly cost of $648 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 $37 a month, and $100 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 FWD at 30 kWh per 100 miles with 253 miles of combined range. Those two figures together give the energy for a full charge, which is where the 76 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 Niro EV uses as much energy per mile as the much larger Ioniq 5 and EV6, 30 kWh per 100 miles, but its 253-mile range means a full charge draws only about 76 kWh from the wall, among the smallest fills on this site. There is also no trim decision to make at the socket: the EPA lists a single front-wheel-drive Niro EV each year, so every trim carries the same figure. What stands out is how little the rating has moved in eight model years. The 2019–2022 first generation was rated 30 kWh per 100 miles with 239 miles of range. The redesigned car added 14 miles of range and was rated 29 for 2023 and 2024, then 30 again for 2025 and 2026. A used first-generation car therefore costs the same per mile as a new one, and a 2023 or 2024 car slightly less. Its Hyundai cousin, the Kona Electric, uses the same 150 kW motor and is rated 29 kWh per 100 miles on 17-inch wheels, about 3% less energy per mile than the Niro.

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.
