How to Split Group Trip Costs Without Making It Weird
Splitting everything equally is the default. It's also frequently the wrong answer.

Equal splitting is popular because it's simple, and it works fine when everyone eats the same, drinks the same, sleeps in equivalent rooms and arrives at the same time. That group does not exist.
The goal isn't perfect accounting. It's that nobody goes home feeling they paid for someone else's better holiday.
Split by category, not by receipt
Trying to itemise every meal is how a trip turns into an audit. Instead, decide in advance which categories are shared and which are individual.
| Category | How to split | Why |
|---|---|---|
| Accommodation | By room quality | The person on the sofa bed should not pay master-bedroom rates |
| Groceries and household | Equal | Everyone uses the coffee and the toilet roll |
| Group dinners | Equal, unless someone doesn't drink | Simplicity is worth a few dollars of imprecision |
| Alcohol | Separate line, split by drinkers | The single most common source of quiet resentment |
| Activities | Pay for what you join | Nobody should subsidise a boat trip they skipped |
| Airport transfers | Per car, per journey | People arriving separately pay for their own car |
The alcohol conversation
If two people don't drink and the bar tab is a third of the food bill, splitting it equally is a real transfer of money from them to everyone else, every night, for the whole trip. Put drinks on their own line. It takes one extra tap in the app.
Rooms
Price the rooms proportionally to the accommodation total. If there are three bedrooms and one is clearly the good one, that room takes a bigger share. A useful rough split for a three-bedroom villa with six people: 40% master, 35% second, 25% the small one. Adjust for ensuites.
If someone wants a private room in a group where others are sharing, they pay the single supplement. That isn't a punishment; it's just what it costs.
People arriving on different dates
Pay per night, not per trip. The friend flying in for the last two nights of a five-night rental should pay for two nights, and the group should have priced that in before booking rather than negotiating it afterwards over dinner.
What to do about the one who never settles
Ask once, clearly, in a message directed to them rather than the group. Most of the time it's genuinely forgetfulness. If it happens twice, don't front their money on the next trip, and don't make a speech about it. Quietly change the arrangement.
A quick fairness test
Before you send the final numbers, read them from the position of whoever spent the least. If it looks fair from there, it's fair. If it doesn't, adjust it before you press send, not after somebody says something.
