About this calculator

This calculator compares the annual running cost of an electric vehicle (EV) against a comparable petrol (gasoline) car, using annual mileage, electricity price per kWh, EV efficiency (kWh/100km or miles), petrol price, and the petrol car's fuel economy. It converts both into a cost-per-distance figure and multiplies by yearly mileage to show the total fuel/energy spend for each.

Car shoppers weighing an EV purchase, and current EV owners wanting to quantify their savings, use it to see the yearly and multi-year difference in running costs — separate from purchase price, incentives, or maintenance. Enter your driving habits and local energy/fuel prices to compare the two side by side.
