What each person owes
Enter the amounts to see the result.
The total is the sum of what everyone paid. Each ticked participant owes an equal share; people left unticked simply get back what they advanced.
Everything is computed in your browser: nothing is stored or sent.
Whole-cent arithmetic with a largest-remainder distribution of the leftovers: the shares are checked against the total by automated tests.
For tracking several expenses over time, with your friends.
The situation this solves
Four of you book a holiday cottage. One pays the deposit, another the balance, a third the tourist tax, and the fourth pays nothing upfront. Nobody paid the same amount, yet everyone should end up with the same share. This calculator adds the payments to get the true total, divides it between the people involved, then compares what each person paid with what they owed.
You can untick someone who put money in without being part of the expense — a parent covering a security deposit, for example. They owe no share and simply get their money back.
Reading the three result blocks
The fair share shows what each person would have paid if the bill had been settled in one go. The net balance compares that share with what they actually put in: positive means they are owed money, negative means they still owe. The balances always add up to zero.
The suggested transfers turn those balances into concrete payments, sending the largest debtor to the largest creditor so the number of transactions stays low.
When one expense is no longer enough
This tool handles one expense at a time. Once there are ten of them, spread across several days and several payers, a standalone calculator becomes tedious — everything has to be re-entered each time someone pays. A shared group recalculates the balances on every addition, from each person's own phone.
Frequently asked questions
Is the total entered or calculated?
Calculated. The total is always the sum of the payments you enter, which rules out the classic mistake of a total that does not match the detail. If the figure does not match your invoice, a payment is missing or an amount was mistyped.
What if the split should not be equal?
This calculator assumes equal shares between the ticked people. For a split by percentage, by weights, by income or by nights stayed, use the matching calculator in the tools list.
Are the cents handled properly?
Yes. Everything is computed in whole cents and indivisible cents are handed out one by one. The shares always add up to exactly the amount paid, and the balances always sum to exactly zero.
