EV vs Petrol Cost Comparison Calculator

Compare running and ownership costs of an electric car and a petrol car, and find your break-even point.

How this EV vs petrol calculator works

It adds up what each car costs to buy and run for the period you choose. The EV’s energy cost blends your home and public charging prices according to how much you charge at home. The petrol car’s fuel cost uses its fuel consumption and the price of fuel.

  • Annual saving = (fuel + servicing) − (electricity + servicing)
  • Break-even = extra purchase price of the EV ÷ annual saving

Resale value is not included here. For a full picture add depreciation with the total cost of ownership calculator.

Frequently asked questions

Is an EV cheaper than a petrol car?
For most drivers the running cost is lower, especially when charging at home. Whether the total cost is lower depends on the purchase price gap and how many years you keep the car. The calculator shows your own break-even point.
What is a good home share of charging?
Most owners with a home charger charge 70–90% of the time at home. If you rely on public fast charging the running-cost advantage shrinks.
Does this include depreciation?
No, only purchase price and running costs. Use the total cost of ownership calculator for resale value, insurance and finance.
