How it works

Fuel used = (distance ÷ 100) × consumption in L/100 km, and cost = fuel used × price per litre. All three inputs are yours.

Assumptions & limits

  • Consumption is entered as litres per 100 km; price as currency per litre.
  • Distance, consumption and fuel price are all user-supplied.

FAQ

Can I use mpg instead?
This tool uses L/100 km and price per litre. Convert your figures first, or use the fuel-economy converter.
