EV vs Petrol Running Costs

Compare running costs of an EV vs a petrol car

Use the EV running cost calculator to compare costs between a petrol or hybrid car, and an EV.

Your driving distance?

Petrol car's fuel usage?

litres/100 km

How much do you pay for fuel?

per litre

How much do you pay for electricity?

cents/kWh

Compare to which EV?

Not sure? Use typical EV running cost

For some of my travel, I'll use a public charger

0 km / year cents/kWh

What will make an EV cheaper to run?

Charge at home as much as possible, preferably overnight, on off-peak rates.
Shop around for the best power company for you.
Charge from solar.

Is there much variation in efficiency between different EV models?

Yes, there can be significant differences in efficiency between different EV models. A large SUV could use up to 50% more recharged electricity than a smaller EV (sedan / hatchback).

Why is there no depreciation and insurance?

This calculator focuses on day-to-day running costs. Depreciation and insurance are highly changeable and are not necessarily correlated with a vehicles level of electrification.

Vehicle depreciation can be brand and model-specific and varies greatly depending on market conditions.
Insurance premiums are based on the driver risk, location, sum insured, vehicle performance and risk, and materials used.

End Notes

Typical (average) EV cost estimate is based on the averaged WLTP consumption values of the five most popular EVs sold locally. Otherwise WLTP consumption rating for each specific model is used.
The WLTP measures recharged electric energy from the mains and applies that to the vehicle's range (Wh/km).
