Split Bill Calculator
Per person with tip, and what rounding up leaves over.
Work out Split Bill. Per person with tip, and what rounding up leaves over. Compounding frequency is an input, not an assumption.
Each person pays
$30.00
$120.00 total including $20.00 tip
Rounding up to a whole unit each leaves $0.00 over — which is the usual practical solution to a split that does not divide evenly, and quietly becomes extra tip. Tipping customs vary far more than the arithmetic does: 15–20% is standard in the United States, service is often already included in much of Europe, and tipping is uncommon or unwelcome in Japan.
How the Split Bill Calculator works
The bill plus tip, divided evenly, with the rounded figure alongside. Rounding up to a whole unit each is the usual practical solution to a split that does not divide cleanly, and this shows exactly how much extra that quietly adds.

Frequently asked questions
How do I split a bill with tip?
Add the tip to the bill, then divide by the number of people. £100 with a 20% tip between four is £30 each.
How much should I tip?
15–20% is standard in the United States. Service is often already included in much of Europe, and tipping is uncommon or actively unwelcome in Japan — customs vary far more than the arithmetic.
What if the split is uneven?
Rounding up to a whole unit each is the usual fix. This page shows the surplus that creates, which normally becomes a little extra tip.
Should I tip on tax?
Conventions differ. Tipping on the pre-tax subtotal is defensible and slightly cheaper; tipping on the total is simpler and more common.
