Fuel Cost Calculator

Distance, fuel economy and price per gallon or litre: the fuel cost of a journey and the cost per mile.

Formula

Fuel cost = Distance × L/100 km / 100 × Fuel price

Assumptions

Consumption and price held constant over the period: seasonal, driving-style and price variations are not modelled.
