How to estimate fuel cost
Use distance, average consumption and the pump price.
Enter the distance
Use the route distance, not the odometer.
Use real consumption
Take an average from the trip computer or a full-tank calculation.
Add other costs
Tolls, parking and wear are separate.
What does this tool do?
Fuel cost is distance multiplied by consumption and price. This calculator uses litres per 100 km and price per litre, and shows the cost per kilometre and per passenger if you split it.
The Formula
Litres = Distance × L/100km ÷ 100; Cost = Litres × Price per litreFrequently Asked Questions
How do I convert MPG to L/100km?
L/100km = 235.215 ÷ US MPG. For UK MPG, use 282.481 ÷ MPG.
Does this include tolls and parking?
No. Add those separately; they can exceed fuel cost on some routes.
