How to use this calculator
- Enter the distance, your fuel use (L/100km) and the fuel price.
- Press Calculate for the fuel used and trip cost.
How it works
Fuel used is the distance times the consumption rate: litres = distance ÷ 100 × (L/100km). Multiply by the price per litre for the trip cost.
Worked example
500 km at 10 L/100km, $2/L. Fuel = 50 L, cost = $100.
Frequently asked questions
Where do I find my fuel economy?
