About EV vs Petrol

Why we built this

Most EV vs petrol comparisons online give you averages. Average mileage. Average electricity prices. Average petrol cars. But your situation isn't average — you drive a specific car, pay a specific tariff, and cover a specific distance each year.

This tool lets you enter your actual numbers and get a result that reflects your life, not a national average. Pick your exact petrol car, the EV you're considering, and your annual mileage. The calculator does the rest.

What the calculator covers

• Fuel vs charging costs

  Annual and monthly running cost comparison between your petrol car and the EV, based on your local prices and driving distance.

• Break-even analysis

  If you enter the price premium of the EV over the petrol alternative, the calculator tells you exactly how many years your fuel savings take to recover the extra cost.

• CO₂ reduction estimate

  The tailpipe emissions avoided each year by switching from petrol or diesel to electric, based on your annual fuel consumption.

• Multiple currencies and units

  Supports USD, EUR, GBP, AUD, and CAD. Switch between km/litres and miles/gallons at any time.

Accuracy and limitations

The calculator uses real-world efficiency data for a large database of petrol and EV models. Car data is sourced from manufacturer specifications and independent testing. Electricity and fuel prices use your inputs, not regional averages.

Results are estimates. They do not account for depreciation, insurance, tyres, maintenance, or battery degradation over time. For a complete financial analysis before a purchase decision, consider all ownership costs, not just fuel and charging.
