The cost of charging an EV depends on where you charge, your electricity tariff, and your car’s efficiency.
You can calculate your own cost with a simple formula.
The basic calculation
Multiply the battery capacity you add (in kWh) by the price per kWh. A car that uses 18 kWh per 100 km on electricity at a given rate will cost 18 times that rate per 100 km, plus a little for charging losses.
Where you charge
- Home on an off-peak EV tariff — usually cheapest
- Home on a standard tariff — moderate
- Workplace or destination chargers — varies, sometimes free
- Public rapid chargers — most expensive
Other factors
Cold weather reduces efficiency. Subscription plans can lower rapid-charging prices for frequent users. Idle fees may apply if you leave the car plugged in after charging.
Compare with fuel
Work out your cost per mile or km for both options. For many drivers with home charging, EVs are cheaper to run, but the gap varies by energy prices.
