General estimate only

This calculator provides a general fuel estimate only. It is not financial, tax, route-planning or vehicle advice, and it does not use live fuel prices.

How this fuel cost calculator works

The calculator uses the distance, fuel efficiency and fuel price you enter to estimate fuel used and fuel cost. It supports miles or kilometres, mpg or litres per 100 km, and per-gallon or per-litre fuel prices.

MPG vs litres per 100 km

MPG estimates how far a vehicle travels on one gallon of fuel. Litres per 100 km estimates how much fuel is used to travel 100 kilometres. Choose the unit that matches the figure you have.

What this calculator does not include

This focused calculator estimates fuel only. It does not include tolls, parking, maintenance, insurance, depreciation, tax, route changes or live fuel prices.
