Tip = Bill × (Percent ÷ 100)
Total = Bill + Tip
Each = Total ÷ People
| Situation | Customary tip |
|---|---|
| US restaurant, table service | 18–20% |
| US bar, per drink | 15–20% |
| Taxi or rideshare | 10–15% |
| Food delivery | 10–15% |
| UK / Europe restaurant | 5–10%, often already included |
| Japan, South Korea, China | None — can cause offence |
- Tip on the pre-tax amount where tax is added separately, as in the US.
- Check for a service charge already on the bill before adding a tip.
- A fast mental 20%: take 10% by moving the decimal one place, then double it.
