How much does it cost to charge a Polestar 2?

A full charge for a 2025 Polestar 2 Single Motor, 19-inch wheels costs about $16.96 at home, at the US average residential electricity rate of 18¢/kWh. A 2021–2023 Polestar 2 costs $15.07 to $17.03 to fill at the same rate, depending on version.

That full charge draws roughly 94 kWh from the wall and buys 314 miles of EPA-rated range — about $0.054 a mile. Filling up the 2025 Polestar 2 costs $11.63 in Idaho, the cheapest state, and $31.32 in California.

What it costs to charge a 2021–2023 Polestar 2

At the US average rate of 18¢/kWh, a full charge of a 2021–2023 Polestar 2 costs $15.07 to $17.03 depending on version, against $16.96 for the 2025 Polestar 2 above. Per 100 miles it runs $5.58 to $6.84, against $5.40.

Before 2024 the Single Motor Polestar 2 drove its front wheels, and its EPA rating is worse than the rear-motor car that replaced it: 31 kWh per 100 miles with 270 miles of range, against 30 and 314 for the 2025 car. The Dual Motor moved more between years than any other version: a 2022 car is rated 38, while the 2023 car is rated 34, the same as that year’s Performance Pack. The 2021 launch car, which the EPA lists simply as the Polestar 2 with all-wheel drive, is rated 37 with 233 miles.

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 Polestar 2 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 Polestar 2 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 Single Motor, 19-inch wheels at 30 kWh per 100 miles with 314 miles of combined range. Those two figures together give the energy for a full charge, which is where the 94 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

This page covers the 2025 Polestar 2, the last model year with an EPA listing: fueleconomy.gov has no 2026 Polestar 2. The rear-wheel-drive Single Motor on 19-inch wheels is rated 30 kWh per 100 miles with 314 miles of range, level with a Hyundai Ioniq 5 or Kia EV6 and a fifth thirstier than a Tesla Model 3. The spread across the range is wide. The same car on 20-inch wheels is rated 31, the Dual Motor 34 on 19-inch wheels and 35 on 20-inch, and the Performance Pack 37 — 23% more energy per mile than the Single Motor, with 60 fewer miles of range. The 2024 car with the same rear-motor layout was rated slightly better: 29 kWh per 100 miles and 320 miles for the Single Motor on 19-inch wheels, and 35 for the Performance Pack. Used shoppers should know that 2024 is when the single motor moved from the front wheels to the rear, and the older front-wheel-drive cars in the table below are rated worse and cover less distance on a charge.

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.

Figures are for the 2025 Polestar 2 Single Motor, 19-inch wheels, plus the 2021–2023 Polestar 2 versions tabled above. Other trims of the same car are rated differently — see above. How these figures are calculated.
