Trip Fuel Cost Calculator

Work out the fuel cost of a road trip from distance, fuel economy and fuel price, split between passengers.

How much will my road trip cost in fuel?

Fuel needed = distance × consumption (L/100 km ÷ 100), or distance ÷ km per litre, or miles ÷ mpg. Multiply by the fuel price for the cost: 300 km at 7 L/100 km uses 21 litres, which costs 37.80 at 1.80 per litre.

Save fuel

Keep tyres at the right pressure.
Remove roof racks when not in use.
