Group Expense Splitter
How it works
The total everyone paid is divided evenly to find each person's fair share. Anyone who paid more than that share is owed the difference; anyone who paid less owes it. The settlement list then pairs off the biggest debtor with the biggest creditor, over and over, until every balance is cleared — the fewest payments that reach the same result as a full itemized reckoning.
Frequently asked questions
How does this minimize the number of payments?
Rather than having everyone settle up with everyone else, it repeatedly matches the person owed the most against the person who owes the most, and has them pay each other directly. Each such payment fully clears at least one person's balance, so a group never needs more transfers than one less than the number of people — far fewer than the free-for-all a shared spreadsheet usually turns into.
What do the positive and negative balances mean?
A positive balance means that person paid more than their fair share — they are owed money. A negative balance means they paid less than their share — they owe money. The settlement list is just a plan for moving money from the negative balances to the positive ones.
Does this handle itemized or unequal shares?
No — it assumes the total is split evenly across everyone in the group, regardless of who ordered what. If your group actually owes different amounts (someone skipped a round, someone ordered the expensive dish), adjust the numbers you enter accordingly; this tool only tracks who paid what up front, not who consumed what.
