What this number means
Rounding the tip is not rounding the total
Rounding the tip raises the tip itself to the next whole unit. Rounding the total raises bill plus tip and leaves the tip whatever remains — 13.00 against 13.50 on an 84.50 bill at 15 %.
The percentage applies to the amount you enter
The calculator takes the percentage from whatever figure sits in the bill field, before or after tax alike. To tip on the pre-tax subtotal, enter that subtotal instead of the total.
No customary rate is built in
The table above only shows what is usual where; the page does not decide it. The percentage is yours to set.
Commonly misread
I said round up, so the tip goes to the next whole unit.
That is one of the two options. Rounding the total up is what most people mean, and on 84.50 at 15 % it gives 13.50 rather than 13.00.
Rounding the total up always adds only small change to the tip.
It adds whatever lifts bill plus tip to the next whole unit. On 67.30 at 20 % the tip goes from 13.46 to 13.70.
The calculator knows whether my bill includes tax.
It does not. It takes the percentage from the figure you type, so type the base you want to tip on.
Reference table
| Where | Customary in the US |
|---|---|
| Sit-down restaurant | 15–20 % of the bill before tax |
| Counter service | Optional, often nothing |
| Taxi or rideshare | 10–15 % |
| Hotel housekeeping | A few dollars per night |
Questions
What does the rounding option do?
Rounding the tip raises the tip itself to the next whole unit; rounding the total raises the bill plus tip. On 84.50 at 15 % that is 13.00 against 13.50 — the second is what most people mean by rounding up.
Do I tip on the amount before or after tax?
The calculator applies the percentage to whatever amount you enter. If you want to tip on the pre-tax subtotal, enter that figure rather than the total.
How much should I tip?
It depends on the country and the service; the table above shows what is customary. The calculator assumes no rate of its own — the percentage is yours to set.
Can I set the tip to 0 %?
Yes, the percentage field starts at 0. Rounding the tip up leaves it at zero, but rounding the total up does not: a bill of 84.50 still rounds to 85 and leaves 50 cents behind. Only on a whole-number bill does every setting give exactly zero.
