Enter annual miles, EV efficiency and electricity price, then petrol efficiency and price per litre.
Running cost estimate
EV annual fuel cost:
Petrol annual fuel cost:
Difference:
EV cost = annual miles ÷ mi/kWh × electricity price/kWh. Petrol cost = annual miles ÷ UK imperial mpg × 4.54609 litres per UK gallon × petrol price/litre. Fuel costs only; losses, public charging, insurance, depreciation and vehicle purchase costs are excluded.
A QUICK WALKTHROUGH
How to use this tool
- Enter annual miles, EV efficiency and electricity price, then petrol efficiency and price per litre.
- EV cost = annual miles ÷ mi/kWh × electricity price/kWh. Petrol cost = annual miles ÷ UK imperial mpg × 4.54609 litres per UK gallon × petrol price/litre. Fuel costs only; losses, public charging, insurance, depreciation and vehicle purchase costs are excluded.
- This compares fuel costs only with your entered prices. It uses UK imperial mpg, does not fetch live data and is not a vehicle purchase recommendation.
