How much does it cost to run a home EV charger?
About $65.33 a month on the typical usage below, at the U.S. average $0.1816/kWh. Set your own rate and usage and the figure updates instantly.
This is the electricity cost of charging at home, not the price of buying or installing the charger — a Level 2 unit plus installation typically runs $500–$2,000 one time.
A Level 2 home charger delivers ~7,000W; nightly charging is a major new household load.

Charging an electric car at home adds a big new load — a Level 2 charger delivers around 7,000W, and a daily top-up for an average commute runs an hour or two. That adds up to roughly 200–400 kWh a month, which often becomes the single largest item on the electric bill (while replacing a much larger gasoline bill).
Because charging is flexible — the car sits plugged in for hours — it's the perfect load to shift to cheap overnight rates, which is where the real savings live.
What drives the cost of running a home EV charger
- Miles driven — more driving means more kWh to put back.
- Your car's efficiency (miles per kWh) and charging losses.
- Crucially, when you charge: peak vs. off-peak pricing can change the cost dramatically.
How to cut it
- Schedule charging for off-peak/overnight hours — many utilities have much cheaper EV rates.
- Only charge to ~80% for daily driving unless you need the full range.
- Check for a utility EV plan or time-of-use tariff built for home charging.
- Even better, charge from rooftop solar in the middle of the day if you have it.
Data basis
- Electricity price
- U.S. Energy Information Administration, Electric Power Monthly, Table 5.6.B, June 2026 year to date, released 2026-08-26. Retrieved 2026-09-11. Average residential revenue per kWh. A benchmark average, not a utility tariff — it excludes the fixed charges, tiers, time-of-use windows, taxes and fuel adjustments on a real bill.
- Appliance energy
- A representative running power for a home EV charger, compiled from published manufacturer specifications and public appliance-energy guidance, and presented as a typical figure with the usual range shown above. It is not a measurement of your unit, and we do not claim a single primary source for it — the nameplate on your appliance, or an hour with a plug-in energy meter, beats any typical figure we can publish.
- Usage model
- Distance driven — 37 miles a day at 3.5 mi/kWh, 10% charging loss
- International prices
- rounded typical household tariffs for each market, in that market's own currency unless the row says US$ equivalent. These are planning benchmarks with no single primary source; enter the per-kWh price from your own bill for an accurate figure.

Common questions
How much does it cost to run a home EV charger per month?
On the assumption shown above — 37 miles a day at 3.5 mi/kWh, 10% charging loss — a home EV charger costs about $65.33 a month, or $783 a year, at $0.1816/kWh. That price is the U.S. average; set your own rate and usage above and the figure updates.
How is that worked out?
Miles driven / vehicle efficiency, grossed up for charging losses, plus charger standby. At 37 miles a day at 3.5 mi/kWh, 10% charging loss that is 11.82 kWh a day, which at $0.1816/kWh costs $2.15 a day.
How can I cut the cost of running a home EV charger?
Schedule charging for off-peak/overnight hours — many utilities have much cheaper EV rates. As a worked example: shifting all charging to an off-peak window priced at 65% of your standard rate takes it from $783 to $509 a year, about $274 less.
Is it cheaper to charge an EV at home or at a public charger?
Charging at home is almost always cheaper. Home electricity at the US average of about $0.18/kWh usually beats public DC fast-charging rates, and shifting to an off-peak overnight EV rate makes it cheaper still. Public fast chargers are priced for convenience on road trips, not daily top-ups.
