International tipping guide
| Country | Customary Tip | Local Etiquette |
|---|---|---|
| United States | 18% – 22% | Standard in sit-down restaurants where servers earn sub-minimum tipped wages. |
| Canada | 15% – 20% | Expected in table-service restaurants, bars, and taxis. |
| United Kingdom | 10% – 12.5% | Optional; check if an optional "Service Charge" (often 12.5%) is already added to the bill. |
| Australia | 0% – 10% | Not expected as hospitality staff receive legally mandated award wages, but 5–10% appreciated for exceptional service. |
How the bill split is calculated
Tip Amount = Bill × (Tip % ÷ 100)
Total Bill = Bill + Tip Amount
Each Person = Total Bill ÷ Number of People
Frequently asked questions
Should you tip on pre-tax or post-tax totals?
Traditional etiquette suggests calculating the tip percentage on the subtotal before sales tax is added, though many electronic card payment terminals default to post-tax totals.
What should you do if an automatic service charge is already included?
If the receipt already itemizes a "Discretionary Service Charge" (common in London and high-end restaurants worldwide), you do not need to add an additional tip unless you choose to reward extraordinary service.
