Gasoline or ethanol: cost per mile calculator

Compare gasoline and ethanol cost per kilometer using your vehicle’s actual efficiency.

Use your car’s own mileage to see which fuel costs less per km — no fixed 70% rule.

We divide price per liter by efficiency in km/L. Break-even uses both efficiency values, not a fixed percentage.

    How it works

    We divide price per liter by efficiency in km/L. Break-even uses both efficiency values, not a fixed percentage.

    Before you decide

    Real-world efficiency changes with traffic, route, vehicle, and driving. The 70% rule is only a historical heuristic and does not replace your data.

    Frequently asked questions

    Does this use the 70% rule?

    No. We compare the prices and actual efficiencies you enter for this vehicle.

    Does the result apply to every car?

    No. Use this vehicle’s efficiency; traffic and driving style affect the result.
