The maths behind it
This tool uses Fuel used = distance ÷ 100 × L/100 km. Total = fuel + tolls + accommodation + food, divided by the number sharing. Every intermediate value is shown on screen, so the result can be checked by hand.
Consumption on a long motorway run is usually better than the official combined figure and much worse with a full car, a roof box, or at high speed. Add 10–15% if the car will be loaded, and remember a return trip is double unless you entered the round distance.
Frequently asked questions
How do I work out fuel cost for a trip?
Divide the distance by 100, multiply by the car’s L/100 km figure to get litres, then multiply by the price per litre. An 800 km trip at 7.5 L/100 km needs 60 litres.
How should we split fuel costs fairly?
Either everyone including the driver splits evenly, or the passengers cover the fuel because the driver supplies the car, its wear and the insurance. Both are fair — agree which one before you set off.
