How to split a bill
- Enter the bill amount before tax.
- Add the tax or service charge percentage printed on the bill, if any.
- Add a tip percentage if you want to tip.
- Enter how many people are sharing. The per-person amount updates instantly.
Formula
Per person = (Bill + Bill × Tax% + Bill × Tip%) ÷ Number of people.
If different people paid different amounts (for example on a trip), use the Trip Expense Splitter. It tells you exactly who owes whom.
