Group Trip Expense Splitter

Settles shared costs after a group trip: enter who paid for what, in any currency, and get who should send how much to whom in as few payments as possible.

How to use

1. Press "New trip", choose the currency to "Settle in" and enter everyone's names.
2. Add each expense with its amount, currency, category and who paid; press "Change the split" when only some people shared it or it is split by amounts or portions.
3. For expenses in another currency, press "+ Add a currency" and type the rate.
4. Read the transfers on the right and press "Copy as text" to send them in a chat.
5. Use "Paste from a spreadsheet" to add many rows at once, and "Save as file" to keep a copy or move it to another device.

How it works

• Each person's balance = what they paid − their share. The transfers settle every balance with the fewest payments (exact for up to 18 people with a balance).
• Amounts are kept in whole minor units (cents, won) and converted with your rates, so the total is conserved exactly; the rounding unit you choose only moves small leftovers, which the page shows per person.
• No live rates are used, and there is no share link. Groups stay in this browser on this device unless you save a file.

Questions and answers

How do I split trip costs when different people paid?

Enter every expense with the person who paid it. The tool adds up what each person paid and owes and lists the payments that even it out.

How are expenses in a foreign currency handled?

Each expense keeps its own currency. It is converted into the settlement currency with the rate you type, for example 100 JPY = 905 KRW.

Can someone be left out of one expense?

Yes. Press "Change the split" and turn off the people who did not take part, or give amounts or portions per person.

Why are some payments rounded?

With a rounding unit of 10 or 100, payments are rounded to that unit. The leftover is assigned so that the totals still match, and "Rounding leftovers" shows who pays a little more or less.
