Split cost calculator

Someone booked the flights, someone else covered the villa, and a third person kept paying for dinner. Put in what each of you spent on shared things and this works out the shortest way to settle up. It all stays in your browser.

How to split costs fairly

The fairest way to handle a group trip is also the simplest. Add up everything that was shared, whatever it was spent on and whoever happened to pay, then divide it by the number of people. That gives everyone the same fair share. Some people paid more than their share and some paid less, and the difference is what moves between you at the end.

This calculator does that, then goes one step further. Instead of a tangle of small transfers, it finds the fewest payments that clear every balance. If three people owe money and two are owed, you often need just two or three transfers rather than everyone paying everyone.

What counts as a shared cost

Keep it to the things the whole group used: accommodation, a rental car, groceries you all ate, a group taxi, tickets you bought together. Personal spending stays personal. If one person went for a fancy dinner while the rest cooked in, that isn't a shared cost and shouldn't go in here.

Do it during the trip, not after

The reason settling up feels awkward is usually that nobody wrote anything down. A week later, memories disagree and the numbers get fuzzy. Jotting each shared payment down as it happens takes a few seconds and removes the whole problem. That is exactly what PocketTrip does while you travel, so the settle-up at the end is just a glance.

On the trip

Track shared costs as they happen

PocketTrip logs who paid for what during the trip and keeps a running settle-up, so there is nothing to reconstruct later. Free on the App Store for iPhone and iPad.
