Fuel cost splitter

Distance, mileage and the price at the pump. It works out the litres, adds tolls and parking, and divides the lot between the people in the car.

What counts as a shared cost

Fuel, tolls and parking are the uncontroversial ones — they exist only because of the journey, so they are split among the people making it.

Wear on somebody's own car is the one worth agreeing before you leave rather than at the end. A per-kilometre contribution is the usual approach, and the cost-per-kilometre figure this calculator shows is a reasonable place to start the conversation. Raising it on day zero is easy; raising it on day four is not.

Mileage is not the number on the brochure

Real mileage is usually well below the advertised figure, and it drops further with a full car, a loaded boot, air conditioning and hills. If you are estimating, take the brochure figure down by a fifth and you will be closer.

For a number you can actually rely on, fill the tank, drive, and fill it again — kilometres covered divided by litres added is your real mileage, on your roads, with your right foot.

Driving versus the train

The cost per kilometre is the figure that makes the comparison honest. Four people in a car is almost always cheaper per head than four train tickets; one person driving alone very often is not, once tolls are in.

What the arithmetic will not tell you is the six hours. Decide that part separately.

Fuel is one line of a road trip. The tolls someone else paid, the hotel, the dinners — a Splitly group keeps all of it and tells you who owes whom at the end.

Frequently asked questions

How do you calculate fuel cost for a trip?
Divide the distance by the vehicle's mileage in kilometres per litre to get the litres needed, then multiply by the price per litre. Double the distance if you are coming back. Tolls and parking are added on top.
How should friends split petrol on a road trip?
Evenly among everyone in the car, including the driver — they are travelling too. If the car belongs to one of them, a small per-kilometre contribution towards wear is a common and fair addition, agreed before setting off.
Should the driver pay for fuel?
They pay their share of it like everyone else, and no more. Driving is the contribution; funding the journey as well is how one person quietly subsidises the trip.
