Smart Split — Shared Expenses

Smart Split works out who owes whom after a trip, a month in a shared flat or a dinner where everyone ordered something different. Add the people, then each expense: what it was for, how much was paid, who paid it, and how it should be shared — equally between some or all of you, by what each person had, by percentage, or by shares (a couple counted as two, for example). It adds everything up and tells you the payments that settle it, as few as it can manage, with every amount exact to the paisa.

1. Add everyone who spent or shared something. “Try an example trip” shows a finished one.
2. Add each expense: a name, the amount actually paid (tax and tip included) and who paid it.
3. Choose how it was shared. For a restaurant bill, “By items” is fairest: enter what each person ordered, and the tax, tip and service charge on top are shared in proportion.
4. Read the result at the top: the payments that settle everything, and each person’s paid, share and balance.
5. Press “Copy link” to send the whole split to the group, or “Copy summary” to paste the payments into a chat.

• Each expense has one payer. If two people paid for one thing, add it as two expenses, one for each amount.
• Amounts are in rupees. The tool does not convert currencies; for a trip abroad, enter what each expense cost in rupees on your card statement.
• Settling up uses at most one payment fewer than the number of people with a balance, and fewer when two people owe and are owed the same amount. It is not always the mathematical minimum — no practical method guarantees that — but it is never more than that bound.
• When an amount does not divide evenly, the extra paise go to the first people in the list, so every share still adds up to exactly what was paid.
• Up to 30 people and 200 expenses. Links to very large splits become long; copy the summary instead.
• Everything is worked out in your browser. The split is saved in the page’s own address, after the # sign — the part a browser never sends to any server — so neither this site nor anyone else sees the names or amounts. A shared link carries them to the person you send it to, so share it only with the group.

In proportion to what each person had. If your items were a third of the food, you pay a third of the tax and tip too. Enter the total you actually paid as the amount, and each person’s items without tax.

₹100 cannot be split three ways exactly. Two people pay ₹33.33 and one pays ₹33.34, so the shares still add up to ₹100. The extra paisa goes to the first person in the list.

It is never sent to a server; the details live in the part of the address after the #, which browsers keep to themselves. Anyone you give the link to can read it, though, and it may be kept in your chat app’s history.

Yes. Press Edit on the expense, change it, and save. The result and the link update straight away.

Use “Equally” and untick them for the expenses they missed. They are only charged for the ones they were part of.
