Tip Calculator

The end-of-meal math problem: what's a fair tip, what's the total, and what does each person owe? Doing it in your head after dinner is how someone always ends up overpaying. This calculator settles it in three fields — bill amount, tip percentage, number of people — with the per-person share as the headline answer, tip included.

The one-tap presets cover the common conventions: 10%, 12%, 15%, 18%, 20% and 25%. What counts as standard varies by country — roughly 15–20% in the US and Canada where tips are a core part of service income, closer to 10% or simple rounding-up across much of Europe, and modest or uncommon in much of Asia. Any custom percentage can be typed directly, including 0% where service is already included.

Everything recalculates live as you adjust — bump the tip a preset, add a late-arriving friend to the split, and the numbers follow. It also shows the tip portion of each person's share separately, which keeps things transparent when one person pays the bill and collects from the rest. No app to install, works offline once loaded, right from the phone at the table.
