How to use the Fuel Cost Calculator
Enter trip distance, fuel efficiency and fuel price. Choose metric L/100 km or US MPG behavior as appropriate.
Formula / calculation logic
Metric fuel = Distance(km) × L/100km ÷ 100. US fuel = Distance(miles) ÷ MPG. Cost = Fuel used × Price per unit.
Worked example
A 500 km trip at 8 L/100 km uses about 40 L. Multiply that by your entered price per litre for the estimated trip cost.
Important notes
Real consumption changes with traffic, speed, load, weather, terrain and vehicle condition. Enter the fuel price yourself rather than relying on fake live data.
