In short
What is this?
Enter what each person actually paid toward a shared cost. The total is split evenly across everyone, and the result shows who is owed money and who owes it — positive means the person is due a refund, negative means they need to pay in.
How to read the settlement
Each person's balance is what they paid minus their even share. A positive balance means they paid more than their share and are owed the difference; a negative one means they owe it.
Balances always sum to zero across everyone, give or take rounding. Include people who paid nothing — they still owe their share, and leaving them out makes the split wrong for everyone.
What this does not do
- Uneven shares. It splits the total evenly rather than by who consumed what.
- Multi-currency, or any conversion.
- Running balances across several occasions. This is one split at a time.
- Suggesting the minimum number of transfers to settle a group.
For an ongoing shared house with weekly costs among several people, a dedicated bill-splitting app does that job better. This is for a single occasion.
Recording it in your own books
If you paid more than your share, the difference is money owed to you — a receivable rather than an expense. Logging the full amount as your own spending makes this month look worse than it is, and then makes next month look better when people settle.
A receivable with a remaining balance also handles the common case of people paying you back at different times, which a single expense line cannot represent.
Getting settled
Most unsettled group costs are not withheld deliberately; they are forgotten, by both sides. Sending the split with a specific amount per person, promptly, resolves the large majority of them.
FAQ
- Can I split unevenly by what each person consumed?
- No, this splits the total evenly. For proportional shares or an ongoing group balance across several occasions, a dedicated bill-splitting app handles that better.
- Should I include people who paid nothing?
- Yes. They still owe their share, and leaving them out changes the per-person amount and makes the split wrong for everyone.
- How do I record this in my own budget?
- The amount above your share is money owed to you — a receivable, not an expense. Logging the full amount as your spending distorts this month and next.
