About this calculator
Enter the trip distance, your vehicle's consumption and the fuel price. Choose metric (km, L/100 km) or US units (miles, mpg) and optionally double the distance for a round trip.
The formula
Fuel = distance × consumption ÷ 100 (metric) | distance ÷ mpg (US)
Worked example300 km at 7 L/100 km and 1.60 per litre → 21 L and 33.60.
