What does the tip calculator do?
At the end of a meal, nobody wants to do mental arithmetic on a phone. Enter the bill, pick a tip percentage and the number of people, and the calculator shows the tip, the total and exactly what each person owes. Turn on rounding and every share is rounded up to a whole amount, which makes paying in cash or by bank transfer easier; the extra goes to the tip.
Tipping customs vary a lot around the world. In the United States and Canada, 15–20% is standard for table service. In much of Europe a service charge is often included, and rounding up or adding 5–10% is common for good service. In many Asian countries tipping is not expected at all. When in doubt, check the bill for a service charge before you add a tip.
How to use it
- Enter the bill amount. Most people tip on the total before tax; use whichever you prefer.
- Choose a tip percentage, or pick Custom and enter your own.
- Enter the number of people sharing the bill.
- Tick round up if you want each share to be a whole number.
How it is calculated
Tip = Bill × Tip % ÷ 100
Total = Bill + Tip
Each person = Total ÷ People
With rounding on, each share is rounded up to the next whole unit, the total becomes that share times the number of people, and the tip is whatever is left above the bill. The effective tip percentage shows what you actually tipped.
Example
Three friends have a bill of 85.50 and leave an 18% tip. The tip is 15.39 and the total is 100.89, so each person pays 33.63. With rounding on, each pays 34; the total becomes 102 and the tip rises to 16.50, an effective 19.3%.
More worked examples
Dinner for four in the US: a $64.80 bill with a 20% tip adds $12.96, for a total of $77.76, or $19.44 each.
Common mistakes to avoid
- Tipping twice. Check the bill for an included service charge before adding a tip.
- Assuming US tipping norms apply everywhere. Customs vary: in Japan tipping is unusual, while in the UK about 10–12.5% is common in restaurants.
- Splitting unevenly by mistake. For different shares, run the calculator once per person, or use the percentage calculator for a custom amount.
