How to split shared expenses

  1. Add everyone who shared costs.
  2. Add each expense: what it was, how much, and who paid.
  3. Choose who it was for. Everyone is selected by default; tap a name to take that person out of this expense.
  4. Read "Settle up": a short list of who pays whom. When those payments are made, everyone has paid exactly their share.

Example: Alex pays the hotel (300) for all three, Sam pays dinner (90) for all three, and Priya pays museum tickets (40) for herself and Sam only.

Shares: Alex 130, Sam 150, Priya 150. Alex paid 300, so is owed 170. Settle up: Priya pays Alex 110 and Sam pays Alex 60. Two payments, done.

Tips for sharing money without arguments

  • Agree on the rules first. Equal split for everything, or only for what each person used? Say it before the trip, not after.
  • Write expenses down the same day. Receipts get lost and memories change. Add them here, or keep a shared ledger in the TallyKnot app that everyone in the group can see.
  • Settle up soon. Small debts between friends are easy to forget and awkward to bring up weeks later.
  • For a shared house, split the monthly bills here and keep the rest in a shared cashbook so everyone sees what was bought.

Equal split or by use?

An equal split is simplest and works well among friends with similar habits. When some people clearly use more (a bigger room, more drinks, an extra night), split those items separately so it stays fair for everyone. For rent in a shared house, splitting by room size or income is also common.

Frequently asked questions

Can an expense be shared by only some people?

Yes. Under each expense, tap the names of the people it was for. By default everyone shares it. For example, if only three of five people went to a museum, select just those three.

How are the settle-up payments chosen?

The calculator works out what each person paid and what their share was. People who owe exactly what someone else is owed pay that person directly; after that, the biggest amounts are matched first. This keeps the list of payments short.

What happens if I add someone later?

A person you add joins the expenses you add after them. Expenses already in the list stay shared by the people who were there, so nobody pays for a dinner they missed.

What if someone paid for something only for themselves?

You do not need to add it. Only add costs that were shared. If you do add it, select only that person under "For", and it will not affect anyone else.

Can I split by different amounts instead of equally?

Each expense is split equally between the people it was for. For an uneven split, add the parts as separate expenses, for example one line for the shared meal and one for the extra bottle only two people had.

Is the list saved?

Yes, in your browser on this device, so you can add expenses during the trip and settle up at the end. Nothing is stored on our server; the PDF summary is made there when you ask for it and is not kept.
