Bill Split Calculator

About the Bill Split Calculator

Bill Split Calculator works out what everyone owes. Enter the subtotal, add tax, service charge and tip as a percentage of the subtotal or as fixed amounts, and choose how many people are paying. Split equally — with optional rounding up — or assign each person their own amount or percentage.

All amounts are calculated in whole paise or cents, so the individual shares always add up exactly to the bill. In custom mode the tool checks that the shares equal the total and tells you precisely how much is missing or over. It only does arithmetic; it does not connect to any payment app or bank.

How to use

1. Enter the subtotal and the number of people.
2. Add tax, service charge and tip, choosing “Percent (%)” (of the subtotal) or a fixed “Amount” for each.
3. Choose Equally (optionally round shares up to the next 1, 5 or 10) or Custom shares (by amount or percentage).
4. Type names for each person if you like, and their shares in custom mode.
5. Click Calculate, then copy individual amounts or the full summary, or download it.

• In custom mode, settle shared dishes first, then split the remainder equally.
• Share the summary in your group chat so everyone sees the same numbers.
