Tip Calculator
See a bill priced at every customary tip rate at once, or split one bill and its tip between any number of people.
Tip Calculator
Calculates the tip for a range of percentages of the cost of the service, and the total including the tip. In the U.S., a tip of 15% of the before-tax price is typically expected.

Shared Bill Tip Calculator
Takes the cost of the service, the number of people and the chosen tip percentage, and works out the tip per person as well as the total cost per person.

How to use these calculators
There are two here, and they answer different questions.
- Tip Calculator — enter the price and see every customary rate priced at once, from 5% to 50%. Use it when you have not decided what to leave and want the options side by side rather than one guess at a time.
- Shared Bill Tip Calculator — enter the price, the rate you have chosen and the number of people, and it works out the tip and the total per person.
A worked example
On a $55 bill, 15% is $8.25 and the total is $63.25. Move up to 20% and the tip is $11.00 for a $66.00 total — the whole decision is $2.75. Split that $63.25 four ways and each person owes $15.81, of which $2.06 is tip.
How much to tip
In the United States, 15% of the before-tax price is the customary baseline for table service, 18–20% is normal for good service, and anything above that is generous. Counter service, takeaway and self-serve are different: a tip there is welcome but not expected. The percentages in the table are not evenly spaced on purpose — the cluster from 12% to 20% is where nearly every real decision happens.
Before tax or after?
Custom is to tip on the price before tax. Tipping on the taxed total is not wrong, it just costs slightly more: on a $55 meal with 8% sales tax, 15% of the taxed total is about 66 cents more than 15% of the meal. Use the before-tax figure here and the arithmetic matches the convention.
Splitting the bill
Work out the tip on the whole bill, add it, then divide — which is the order the Shared Bill calculator uses. Dividing first and having everyone tip their own share gives the same total in theory, but in practice each person rounds down and the server ends up short.
Watch for a gratuity that has already been added. Many restaurants apply one automatically to larger parties, commonly 18–20%, in which case a further tip is entirely optional.
The mental shortcut
Move the decimal one place left for 10%, then adjust. On $55 that is $5.50, so 15% is $5.50 + $2.75 = $8.25 and 20% is just double, $11.00. Worth knowing when the bill arrives and your phone is in your coat.
Tipping is not universal
Customs vary sharply. In much of East Asia — Japan especially — tipping can be read as insulting. Across much of Europe service is included and rounding up is plenty. In the United States it is widely expected, and is often built into what a server is actually paid, which is why leaving nothing carries the weight it does. Worth a moment's research before travelling.

Frequently asked questions
How much should I tip?
In the United States, 15% of the before-tax price is the customary baseline for table service, 18–20% is normal for good service, and 20%+ is generous. The table here prices every rate from 5% to 50% on your bill at once, so you can see what the difference actually costs rather than guessing.
Do I tip on the price before or after tax?
Custom in the U.S. is to tip on the before-tax price. Tipping on the post-tax total is not wrong, it simply costs a little more — on a $55 meal with 8% tax, tipping 15% of the taxed total adds about 66 cents.
How do I split a bill and its tip?
Work out the tip on the whole bill, add it, then divide by the number of people — which is what the Shared Bill calculator does. Dividing first and tipping separately gives the same answer, but rounding each share can leave the server short.
What if a service charge or gratuity is already added?
Check the bill before tipping again. Many restaurants add a gratuity automatically for larger parties, often 18–20%. If one has been applied, an extra tip is entirely optional.
Is tipping expected everywhere?
No, and it is worth checking before you travel. In much of East Asia, including Japan, tipping can be seen as insulting. In many European countries service is included and small change is enough. In the U.S., tipping is widely expected and is often factored into a server's pay.
How do I calculate a tip in my head?
Move the decimal point one place left to get 10%, then adjust. On $55 that is $5.50, so 15% is $5.50 plus half again ($2.75) = $8.25, and 20% is simply double ($11.00). The table below does it exactly, but the shortcut is quick at the table.
