Work out how much it costs to charge your electric car at home or in public, and what that is per mile or km.
How EV charging cost is calculated
Cost = energy added ÷ (1 − losses) × price per kWh. Energy added is the battery size multiplied by the percentage you charge. Losses cover the heat lost in the charger, cable and battery, which is why you pay for slightly more than the battery stores.
For a public fast charger enter that network’s price per kWh. Many networks charge more at peak times, and some add a session or idle fee that is not included here.
Frequently asked questions
How much does it cost to charge an electric car at home?
Multiply the energy you add by your home tariff. For example, adding 36 kWh at 0.15 per kWh costs about 5.40 before losses.
Is charging losses 10% realistic?
Yes for AC home charging. DC fast charging is usually a bit more efficient at the wall because the conversion happens outside the car.
