Sharing fuel or a hire car

If the group only wants to share fuel, divide the fuel used for the trip. For a hire car, use the rental invoice and fuel expenses instead of adding a mileage rate for the owner’s running costs.

Questions

What is the official Australia mileage rate?
The listed rate is 0.91 AUD a kilometre, from Federal Register of Legislation (legislation.gov.au), checked on 30 July 2026. See the conditions above and the source linked beneath the country selector.
Why use a government mileage rate for a shared trip?
A published rate gives the group a reference for running costs beyond fuel. Check the source and date beneath the country selector: the rate’s purpose and conditions vary by country. You can edit it to use an amount the group agrees on. This calculator divides trip costs; it does not calculate a tax claim.
Should the driver pay a share of the mileage too?
The group decides. By default, the passengers cover the full calculated cost. Turn on the driver toggle to give the driver one share as well. Passenger shares remain adjustable, so someone who travelled half the distance can take half a share.
