Group Trip Expense Splitter

Add every shared expense — who paid and how much — and this tool instantly works out each traveler's fair share and the fewest payments needed to settle up. Everything runs in your browser; nothing is uploaded or stored.

📖 How it works & FAQ

Split trip costs without the awkward math

On any group trip, expenses land unevenly: one person books the hotel, another covers dinner, someone else keeps filling the gas tank. By the end, nobody remembers who is up or down. This splitter does the accounting for you. Enter each shared expense, its amount, and who paid, and it computes the total, divides it evenly across the group, and shows each person's net position — how much they paid versus their fair share.

Better still, it produces a simple settle-up plan: the smallest practical set of payments so everyone ends even. Instead of six people passing cash in circles, you might see just two transfers, like “Sam pays Alex $88.25.” All math runs in cents to avoid rounding drift, so the balances always add up exactly. Everything happens in your browser — no account, no upload, no data stored. Amounts are treated as plain numbers, so use any single currency. Estimates only, not professional financial advice; exchange rates, fees, and local costs vary.

How to use it

  1. Set the number of people in your group (2–30).
  2. Optionally type names, separated by commas, so results read naturally.
  3. For each shared cost, fill in the expense name, the amount, and who paid. Click “+ Add expense” for more rows, or Remove to delete one.
  4. Results update live: total spent, fair share per person, each person's balance, and the who-pays-whom settle-up list.

FAQ

How does the settle-up work?
People who paid more than their share are owed money; people who paid less owe it. The tool matches the largest debts against the largest credits repeatedly, which settles the group in very few transfers.
Can it handle uneven splits, like someone skipping a dinner?
This tool splits every expense evenly across the whole group. For a cost only some people shared, split it separately with a smaller group size, then combine the results.
Why does one person's share differ by a cent?
When the total does not divide evenly, leftover cents are assigned one each to the first people on the list so the books balance to the penny.
Is my data saved anywhere?
