Overview
The Tip Calculator makes it easy to split restaurant bills and calculate gratuity. It supports custom tip percentages, per-person bill splitting up to 10 people, and includes quick-select buttons for the most common tip rates — 15%, 18%, and 20%.
How to Use
Enter the total bill amount, then select a tip percentage using one of the quick buttons or type a custom percentage. If splitting the bill, use the person count stepper. The calculator instantly displays the tip amount, tip per person, total bill, and total per person. All values update in real time.
Background & Context
Tipping customs vary widely by country. In the United States, a 15–20% tip is standard for restaurant service. In Japan, tipping is considered rude. In the UK, 10–15% is common. The word “tip” may originate from 18th-century English coffeehouses where boxes were labeled “To Insure Promptness” (T.I.P.), though this etymology is debated by historians.
