About this calculator
Estimate trip fuel use and cost from distance and fuel economy.
Use your real-world fuel economy for a better estimate.
Formula
Fuel used = distance × L/100km ÷ 100. Cost = fuel used × price per litre.
Example
300km at 7L/100km uses 21L.
Accuracy
NUMTX shows the assumptions next to the calculation so you can replace defaults with values that match your situation. For measurements, supplier rates, fees, interest, tax or regulated work, confirm important figures with the appropriate official or professional source.
