How to split travel costs with friends fairly

• Which costs are shared (accommodation, car hire, groceries) and which are personal (souvenirs, your own drinks).
• Whether people who skip an activity still pay for it — usually no.
• When you'll settle up: daily, or once at the end of the trip.

Split equally for things everyone uses — the villa, the hire car, the welcome-night dinner. It's simple and nobody feels watched.

Use a custom split when only some people are involved: the four of you who went diving, or the two who took the private room. Being precise here is what keeps the equal splits feeling fair.

One person often pays a large deposit months in advance. Log it straight away, with the full group as the split, so it doesn't get forgotten. Ask everyone to pay their share before the trip — it's much easier than chasing it afterwards.

Trying to rebuild a week of spending from bank statements on the flight home never works. Take ten seconds to log each shared cost when it happens: what it was, how much, who paid and who it's split between.

Instead of everyone paying everyone back, work out each person's overall balance — who is up, who is down — and settle with as few transfers as possible. In a group of eight, that's often four or five payments instead of twenty.

In Planazo, any plan with a cost appears on the Money tab. Mark it paid and choose to split it with the whole group or just selected people. Planazo keeps a running 'who's up, who's down' balance, and expenses can be edited later if the split changes.
