How to use this tool
Name your group and add participants. Record each bill, select who paid and who shares the cost, and choose equal, weighted or exact split amounts. Live balances show who should receive money or pay it back. Record repayments as they happen.
Quick steps
- Enter a group name and currency, then add the people sharing costs.
- Add a bill, choose its payer and included people, and divide it equally, by shares or exact amounts.
- Review live balances and suggested repayments, record payments, then export a report or share a snapshot link.
Practical tip
Check your chosen currency before entering expenses. Use Export JSON for a portable backup. Sharing a link creates a readable snapshot, not live multi-device collaboration; avoid sharing personal finance details publicly.
Common questions
How does the group expense splitter calculate who owes whom?
For each expense, the payer receives credit for the full amount and each included participant owes their assigned share. Recorded repayments also adjust balances. The total balance always nets to zero.
Can I split an expense unequally?
Yes. Select Equal for even splitting, Shares for weighted amounts such as 2:1:1, or Exact amounts when each person's share is known. All calculations round to cents and the individual shares always sum to the bill.
Is this free, private and without a login?
Yes. The tool works in your browser and saves only in this device's local storage. Exported backups and share links are shared only when you choose; anyone who receives a snapshot link can read its details.
Does sharing let my friends edit the same group?
No. A shared link contains a snapshot at the time you created it. Each person opens their own copy; changes do not automatically synchronize across devices.
Does changing currency convert exchange rates?
No. Currency selection changes the labels only. Existing amounts are not converted; use a consistent currency and calculate conversions separately before entering an expense.
