How Fuel Costs Are Calculated
The general formula for fuel cost:
- Using MPG: Fuel Cost = (Distance ÷ MPG) × Price per Gallon
- Using L/100km: Fuel Cost = (Distance ÷ 100) × L/100km × Price per Litre
- Using km/L: Fuel Cost = (Distance ÷ km/L) × Price per Litre
The calculator automatically converts between unit systems. When you select a metric fuel economy unit, the fuel price label updates to "per litre".
