How the Fuel Cost Calculator works

The calculator first determines how much fuel the trip consumes by dividing the distance by your vehicle's efficiency (miles per gallon or liters per 100 km). It then multiplies the fuel needed by the price per unit of fuel to get the total cost.

Formula

Cost = (Distance / Efficiency) × Fuel Price
