How to track expenses on a group trip
A trip compresses months of shared spending into a few days, paid by whoever is nearest the card reader. It is the fastest-moving shared money most people ever handle, and the least suited to being remembered.

Before you go: the costs everyone forgets
The single biggest source of trip-money unfairness is not what happens on the trip. It is what was paid months earlier and never counted.
- Accommodation deposits, often paid by one person as soon as the dates were agreed.
- Flights or train tickets booked individually at different prices.
- Event or attraction tickets bought when they went on sale.
- Car hire or insurance paid in advance.
- A group booking fee that one person absorbed.
Somebody is frequently several hundred pounds out of pocket before the trip starts, and by the time everyone is home nobody remembers. Record these first, on the day the group is created.
Two things to agree in advance
- What is shared. Accommodation and transport almost always are. Meals, drinks, taxis and gifts are where groups differ, and where the assumption gap opens.
- How individually-booked travel is handled. If people paid wildly different fares for their own flights, decide whether that is shared or personal before anyone lands.
During: one habit, ten seconds
Whoever pays, records — right there, while the amount is still on the screen. Not one designated bookkeeper: that person becomes a bottleneck and misses half of what everyone else paid for.
| Capture | Why |
|---|---|
| The final amount | Including any service, tourist tax or card fee. Split the number actually charged. |
| Who paid | This is the whole basis of the balance. Without it there is no creditor. |
| Who shared it | The most-skipped field, and the one that makes the numbers right. Two people in a taxi is not four. |
| The currency | Keep it in what was actually paid. Do not convert in your head at the table. |
| A photo, if unusual | For anything large or confusing. Removes all doubt a fortnight later. |
Do not settle mid-trip
Transferring money during the trip creates more transactions, not fewer, and usually leaves the ledger half-reconciled. Let the balances accumulate. The whole point is that they net out at the end.
Foreign currencies, handled honestly
Expenddy records each expense in a currency and nets balances separately per currency. It does not convert between currencies and applies no exchange rate of its own.
That sounds like a limitation and is actually the safer behaviour. An automatic conversion has to pick a rate — on the day of the expense, the day of settling, or the day the card cleared — and every choice silently changes what somebody owes. Leaving it to the people involved keeps the rate a decision rather than an assumption.
The two approaches that work
- Record in the local currency and settle each currency separately, or agree a rate between yourselves at the end and record one settlement.
- Record in your home currency using what your bank actually charged. If most of the trip went on cards, this figure already includes the bank's rate and fees — it is the amount genuinely paid, so it is the honest number to split.
Pick one at the start of the trip and make sure everyone uses the same one. Mixing them is what produces balances nobody can reconcile.
The expenses only some people shared
Every trip has them: two people took a taxi, four went to the museum, one person hired a bike. These are not edge cases — they are most of the difference between the final balances.
What subsets do to the numbers
Six people on a trip. Three expenses in one day, each shared by a different subset.
| Expense | Amount | Shared between | Share each |
|---|---|---|---|
| Apartment, per night | £240 | All six | £40 |
| Boat trip | £150 | Four of them | £37.50 |
| Late-night taxi | £28 | Two of them | £14 |
Result: One day, and the six people already owe four different totals depending on which subsets they were in: £40 for the apartment alone, £54 with the taxi, £77.50 with the boat trip, and £91.50 with both. Splitting the day's £418 evenly would charge everyone £69.67 — a figure that is wrong for every single person.
After: settle within a week
When the trip ends, each person has one number. Pay it, record it as a settlement, and the balance clears.
Settle quickly. Trip balances left for months become genuinely awkward to raise — the shared context has evaporated, and asking about £60 in November for a trip in July feels like an accusation in a way it does not on the flight home.
Keep the group afterwards rather than deleting it. It is the record of what the trip cost, which is the most useful thing you can have when planning the next one, and it exports to CSV.
Doing this in Expenddy
Create a Trip group before you leave, add everyone travelling, and record the pre-trip costs immediately. During the trip everyone records their own payments, choosing who shared each. At the end, each person settles once. The trip expenses page works through a complete four-person example with the final transfers.
Questions
Can I use Expenddy for trips?
Expenddy has a Trip group type for exactly this. During a trip, whoever pays for a hotel, a taxi or a meal records it, and the balances build up as you go instead of being reconstructed afterwards. At the end of the trip each person can see what they owe and settle in one payment rather than many small transfers.
Does Expenddy support multiple currencies?
Expenddy supports 8 currencies: USD, GBP, EUR, INR, CAD, AUD, AED, PKR. Each expense is recorded in a currency and balances are netted separately per currency. It does not convert between currencies or apply exchange rates, so a debt in one currency is never cancelled by a payment in another.
Can I record settlements when someone pays me back?
When a payment happens you record it in Expenddy as a settlement, and the balances clear by that amount. Expenddy keeps a dated settlement history of who paid whom. If a settlement was recorded by mistake it can be voided or edited, and the balance movement is reversed exactly — the original entry is annotated rather than deleted, so the history stays accurate.
