Tipping customs vary by country and change over time. These figures are estimates for planning only — always follow the local norm and check whether a service charge is already on the bill.
The traditional default
Fifteen percent is the traditional US restaurant tip for acceptable, everyday service. It used to be the default, and many older etiquette guides still cite it, though younger diners have drifted toward eighteen or twenty. If the service was fine but not memorable, fifteen percent remains a reasonable, defensible choice — and this tool shows exactly what that looks like on your bill.
When 15 percent is the right call
Fifteen percent is the traditional US restaurant tip for standard, unexceptional service. It remains a common default for casual dining, counter service and situations where the service was fine but not memorable. Some people still use it as their everyday rate, while others reserve it for weaker service and move to 18 or 20 percent for better experiences.
This tool locks the rate at 15 percent so you do not have to type it. Enter the bill and the number of people, and it shows the tip, total and per-person amount at exactly 15 percent.
15 versus 18 or 20
The gap between 15 and 20 percent on a $100 bill is only $5, but it signals how you felt about the service. If you are unsure, 18 percent is the modern safe middle; choose 15 when the service was merely adequate. The dedicated 18 and 20 percent tools are there if you prefer those rates.
Worked example
A $100 bill at 15 percent, shared by two.
| Bill | $100.00 |
| Tip at 15% | $15.00 |
| Total | $115.00 |
| Per person | $57.50 |
Fifteen percent on $100 is a straightforward $15.
