Split a restaurant bill with a tip
Work out the tip, the total, and each person's share — and why the rounded shares collect a few cents extra.
Tools used in this guide
The job
The check is $86.40 and the table wants to leave 18% and split it four ways. Multiply the bill by the percent to get the tip, add it to get the total, then divide — and the cents rarely land evenly.
Why shares are rounded up
$86.40 with 18% is a $15.55 tip, so the total is $101.95. Split four ways that is $25.4875 — the tool rounds each share up to $25.49 and shows the extra cent that rounding collects. Nobody has to hunt for loose change.
If you want an even split instead, lower one share by the remainder shown.
What is not included
Tipping customs differ by country and venue, and some bills already include a service charge — check for a “service” or “gratuity” line before adding a tip. The math here is percent-of-bill only.
