FAQ
How do I calculate fuel cost for a trip, for free?
Enter the distance, mileage (km per litre) and the price per litre, and this page computes the litres needed and the total cost, on your device with no upload.
What if it's a round trip?
Tick the round-trip option and the tool doubles the distance before computing the fuel and cost.
Is anything uploaded?
No. Everything runs in your browser and nothing is transmitted or stored, which you can verify by turning off your Wi-Fi.
Where do I find my mileage?
Use your vehicle's real-world km-per-litre; the manufacturer figure is a starting point but actual mileage varies with conditions.
Limits
