The modern middle
Eighteen percent is the modern American middle ground: a bit more than the old fifteen-percent standard, a bit less than the twenty-percent mark for excellent service. Many people set it as their default and only move for unusually good or bad experiences. It signals satisfaction without extravagance, which is why it has become the most common suggested rate on receipt machines.
Why 18 percent is the common choice
Eighteen percent has become the everyday US tip for good, ordinary service. It sits between the old 15 percent standard and the newer 20 percent expectation, so it feels fair without being generous. Many people set 18 percent as their default and only move up for excellent service or down for poor service.
This tool fixes the rate at 18 percent. Enter the bill and headcount to see the tip, total and per-person amount without typing the percentage.
18 as the safe middle
If you are uncertain what to leave, 18 percent is the least likely to feel wrong. It acknowledges good service without the top tier reserved for memorable experiences. The 15 and 20 percent tools let you shift if your experience was weaker or stronger.
Worked example
A $100 bill at 18 percent, shared by two.
| Bill | $100.00 |
| Tip at 18% | $18.00 |
| Total | $118.00 |
| Per person | $59.00 |
Eighteen percent on $100 is a clean $18.
