Group Travel Cost Splitter

The simplest approach is to split shared costs equally by the number of travellers. Shared costs include accommodation (where everyone stays together), shared car hire, group tours, and any meals where everyone eats together. Individual costs such as personal shopping, solo activities, and single-room premiums should be borne by the individual. This calculator splits shared costs equally and lets you add personal costs per person.

Many groups track expenses in a shared spreadsheet. Commercial apps exist for expense splitting but the core mathematics is straightforward: keep a running total of who paid what for shared expenses, then at the end calculate each person's share and determine the minimum number of transfers to settle the balance. This calculator provides the per-person share for a trip budget you enter.

Equal splitting is the default convention for group travel. If the group agrees to an alternative arrangement (e.g., higher earners pay a larger share for accommodation upgrades they prefer), this should be agreed before booking rather than after. Alternatively, some groups use a tiered room arrangement where those who want the premium option pay the difference.

Flights are usually paid individually since everyone books their own ticket (with potentially different prices depending on booking time and seat choice). However, if the group books on the same itinerary or as a group booking, the equal split approach applies. This calculator has a toggle for whether to include flights in the shared split.

When a group member drops out after non-refundable costs are committed, their share of those costs is typically borne by the remaining group (resulting in a higher per-person share) or by the departing person, depending on the group's prior agreement. It is good practice to agree on the cancellation policy within the group before making non-refundable bookings.
