EV Charging Cost Calculator
Work out how much it costs to charge your electric car, per full charge, per journey and per mile, and compare typical home vs public rapid charging prices.
Estimate only. EV charging cost figures are estimates based on the rate, battery size and efficiency you enter, actual costs vary by energy supplier, charge point network, charging speed and losses. Source (typical UK rates): Zap-Map EV charging price index.

How EV charging cost is calculated
The cost of a full charge is your battery's usable capacity in kWh, multiplied by the percentage you're charging to, multiplied by your electricity rate in pence per kWh. The cost of a journey is the distance divided by your car's efficiency (miles per kWh), that tells you how many kWh the trip uses, multiplied by the same rate. Home charging on a standard or off-peak tariff is typically far cheaper than public rapid or ultra-rapid charging, so it's worth comparing both before a long trip.
