The short answer: log every cost with who paid it and whether it's shared by the group. Add up what each person paid, work out each person's fair share, and the difference tells you who owes money and who is owed. Settle up once at the end instead of after every coffee.
Agree the rules before you go
Most awkward money moments on group trips come from assumptions. A two-minute chat beforehand helps:
- Which costs are shared equally (accommodation, car hire, group meals)?
- Which are personal (souvenirs, your own flights, drinks)?
- Will anyone pay a different share, for example for a bigger room?
- When will you settle up?
Step 1: Log every cost
Record the date, what it was, the amount, who paid and whether it's shared or personal.
Step 2: Total what each person paid
Step 3: Work out each person's fair share
Fair share = (total shared costs ÷ number of people) + any personal costs they paid for themselves.
Step 4: Compare paid vs fair share
| Person | Paid | Fair share | Balance |
|---|---|---|---|
| Alex | £480 | £277 | Is owed £203 |
| Sam | £350 | £277 | Is owed £73 |
| Jo | £38 | £315 | Owes £277 |
Made-up example. Jo's fair share is higher because Jo's £38 was a personal cost.
Jo pays £203 to Alex and £74 to Sam (rounded), and everyone is square.
Frequently asked questions
What if someone joins for only part of the trip?
Split the costs for those days between the people who were there. Logging dates makes this easier.
Should we use a shared spreadsheet?
It helps. When everyone can see the log, there are fewer surprises at the end.
Do it in a template
The Split & Settle tab in our Holiday Budget Planner works this out for up to 8 people. Mark each cost as "Everyone" or "Just me" and it shows who owes who.
