How to split fuel costs on a shared drive

Record each fuel purchase under whoever paid and split it between the people sharing that part of the journey. Use separate expenses when the passenger group changes. Questions

Record each fuel purchase under whoever paid and divide it between the people sharing that part of the drive. If someone joins or leaves partway through, keep those legs separate. Taking turns at the pump can leave people paying different amounts.

Track the cost of the drive

  1. Agree what the group will cover

    Choose actual fuel costs or an agreed mileage rate. If the mileage rate includes fuel, do not add the same fuel cost again.

  2. Record each purchase

    Add fuel under whoever paid and select the passengers sharing it.

  3. Add tolls and parking

    Include charges for the shared journey. Keep personal detours and unrelated parking separate unless everyone agrees to cover them.

Using someone's own car

Fuel is only part of running a car. A mileage rate can also account for wear and servicing. The mileage split calculator shows the cost using distance and a selected rate. Check what the rate includes before adding other expenses.

When one transfer is enough

If one person pays for a short journey and everyone rides the same distance, divide the agreed cost by the passenger count. A room is useful when several people pay or the passengers change.

You can add expenses without a connection; they stay on your device and send when you reconnect. Editing expenses and recording payments need a connection.

Pay each other by cash, bank transfer or another method you agree on, then record the payment in Split. Split does not move money or check with your bank.
