Tip Calculator
The tip, the total, and what each person actually hands over — including the awkward part, which is that a bill split four ways rarely divides evenly.
Runs on your device — nothing is sent anywhereRounding each share up is what actually happens at a table. The extra goes to the tip, and the calculator says how much it was.
No currency symbol, because the arithmetic is identical everywhere and guessing wrong is worse than saying nothing. Whether to tip at all, and how much, is a question about where you are.
How it works
No account, no app, and nothing leaves your phone.
Put in the bill
The amount before the tip. If tax is already on the bill, decide whether you are tipping on it — see below, opinions differ.
Choose a percentage
The buttons cover the usual ones; the slider does anything else. What is usual depends entirely on the country.
Split it and round
Set the number of people. Rounding each share up is what happens in practice, and the calculator shows how much that added.
When it earns its place
A table of six and one bill
The arithmetic is easy and doing it out loud, correctly, while everybody watches is not.
Working out a share that divides evenly
A total that ends in a 3 does not split four ways. Rounding each share up settles it in a second.
Checking a suggested tip on a card machine
The suggestions are sometimes calculated on the total after tax, and sometimes start at 25%.
Travelling somewhere with different customs
Twenty per cent is standard in one country and mildly insulting in another. The table below is the part worth reading.
The percentage is the easy half
Multiplying a bill by 0.18 is not why anybody opens a tip calculator. Two other things are: knowing what the percentage should be where you are standing, and splitting the result between people without leaving somebody a coin short.
Splitting is where the arithmetic gets awkward
A bill of 94.40 with an 18% tip comes to 111.39. Divided between four people that is 27.8475 each — which is not an amount of money.
Round each share down and the group is short. Round to the nearest and it may still not add up. What actually happens at a table is that everybody rounds their own share up, and the difference quietly becomes part of the tip.
That is what "round each up" does here, and it tells you what the extra was and what the tip percentage became — because rounding four shares up can move an 18% tip to 18.5%, which is worth knowing rather than discovering.
Before or after tax
Where tax is added at the till rather than shown in the price, tipping on the pre-tax amount is traditional and tipping on the total is now common. On a 100 bill with 8% tax the difference between 20% of 100 and 20% of 108 is 1.60 — small enough that nobody will comment, which is why the practice drifted.
Card terminals almost always calculate their suggestions on the post-tax total, and the higher of the two.
What is normal, by country
This is the part that varies, and getting it wrong in either direction is uncomfortable. Restaurant service, roughly:
| Where | Usual | Notes |
|---|---|---|
| United States, Canada | 18–22% | Expected. Wages are set assuming it |
| Mexico | 10–15% | Sometimes already added as propina |
| Argentina, Chile, Peru | 10% | Customary, and often suggested on the bill |
| Brazil | 10% | Usually printed on the bill; optional in law |
| United Kingdom, Ireland | 10–12.5% | Often added as a service charge — check before adding more |
| France, Italy, Spain | 0–10% | Service is included. Rounding up is normal, a percentage is not |
| Germany, Austria, Netherlands | 5–10% | Round up, or say the total you want to pay |
| Japan, South Korea, China | None | Not customary, and can genuinely cause confusion |
| Australia, New Zealand | 0–10% | Not expected; for good service in nicer places |
| India | 5–10% | Check whether a service charge is already on the bill |
| UAE, Gulf states | 10–15% | A service charge is often included and does not reach staff |
Two rules travel well. Check whether service is already on the bill — in much of Europe and Latin America it is, and adding a full tip on top means paying twice. And where tipping is not customary, not tipping is correct, not stingy.
Percentages that are easy in your head
Move the decimal point one place left: that is 10%. From there:
- 15% — 10% plus half of it again
- 20% — 10% doubled
- 18% — 20% minus a tenth of that, or simply a little under a fifth
On an 84 bill: 10% is 8.40, so 20% is 16.80 and 15% is 12.60. That is most tips solved without a phone.
Why there is no currency symbol
Because the sum is the same in every currency, and picking one would be wrong for most people using this. The numbers you type come back in the same units you were thinking in.
Common questions
How much should I tip?
It depends entirely on where you are. 18–22% is expected in the United States and Canada; 10% is customary across much of Latin America; service is usually included in France, Italy and Spain; and tipping is not customary in Japan, South Korea or China. The table above covers the common cases.
Should I tip on the amount before or after tax?
Before tax is traditional where tax is added at the till; after tax is now common and is what card terminals suggest. On a 100 bill with 8% tax the difference is about 1.60.
How do I split a bill that will not divide evenly?
Round each share up. That is what happens in practice, it covers the total, and the small excess goes to the tip. The calculator shows exactly how much it added and what the tip percentage became.
What if a service charge is already on the bill?
Then the tip is already there. Adding a full percentage on top means paying twice, which is a common and expensive mistake in the UK, much of Europe and parts of Asia. Look for "service", "servizio", "coperto" or a percentage line before adding anything.
How do I work out 20% in my head?
Move the decimal point one place left for 10%, then double it. For 15%, take the 10% and add half of it again. On an 84 bill that is 8.40, so 16.80 or 12.60.
Why is there no currency symbol?
Because the arithmetic is identical in every currency and choosing one would be wrong for most people. The numbers come back in whatever units you typed.
