How to use the tip calculator
- Type the bill amount.
- Choose a tip – 15%, 18%, 20% or 25% – or pick Other to enter your own.
- Move the slider to split the bill between several people. Tick round each share up to avoid coins; the extra goes to the tip.
The formula
Tip = Bill × tip % ÷ 100
Each person = (Bill + Tip) ÷ number of people
Worked example
A dinner bill of $85 with an 18% tip: $85 × 0.18 = $15.30 tip, so the total is $100.30. Split between four people, each pays $25.08. Rounded up to $26 each, the group pays $104 and the tip becomes $19 (about 22%).
How much to tip
| Country | Restaurants | Good to know |
|---|---|---|
| United States | 15–20% | 18–20% is common for good table service; servers often earn a low base wage. |
| Canada | 15–20% | Similar to the US. |
| United Kingdom | 10–12.5% | Check the bill first – a service charge is often already added. |
| Germany, Austria | 5–10% | Round up and tell the server the total you want to pay. |
| France, Italy, Spain | 0–10% | Service is usually included; leaving small change is a nice extra. |
Tip on the amount before or after tax?
In the US many people tip on the amount before sales tax. The difference is small – on an $85 bill with 8% tax, an 18% tip is $15.30 before tax or $16.52 after tax – so either is fine.
Tipping customs change and vary by city and type of service. These figures are general guidance, not rules.
