How this calculation works
Distance is entered by you, not fetched from a map. Enter the complete return distance if needed. The allowance adds distance, not a guarantee about traffic or consumption. Parking, tolls, lodging and vehicle wear are excluded. The final fuel cost rounds once to the currency’s minor unit.
Adjusted distance × fuel used per distance × price per litre. 1 mile = 1.609344 km; US gallon = 3.785411784 L; Imperial gallon = 4.54609 L.
Your calculation, step by step
- Add the distance allowance.
- Convert the selected economy convention to litres required.
- Multiply by the entered per-litre price; round once.
A worked example
300 km plus 10% at 7 L/100 km uses 23.1 L. At 1.50 per litre, fuel costs 34.65.
