Tip Calculator (Split the Bill)
By Santaji GadepatilinUpdated October 27, 2026
A tip calculator works out the tip and splits the bill evenly between everyone at the table.
How to use the tip calculator
Enter the bill, the tip percentage and the number of people. The tip, total and amount per person are calculated.
Example
A bill of 85 with a 15% tip, split 4 ways:
- Tip = 12.75
- Total = 97.75
- Each person pays 24.44
Quick tip table (bill of 50)
| Tip | Amount |
|---|---|
| 10% | 5.00 |
| 15% | 7.50 |
| 18% | 9.00 |
| 20% | 10.00 |
Check the bill first — some restaurants already add a service charge.
Tipping customs around the world
| Country / region | Restaurants | Notes |
|---|---|---|
| United States | 15–20% | Tips are a large part of servers’ pay |
| Canada | 15–20% | Similar to the US |
| United Kingdom | 10–12.5% | Often added as a service charge |
| Europe (most) | Round up to 5–10% | Service is often included |
| India | 5–10% | Check for a service charge first |
| Australia, New Zealand | Optional | Wages do not rely on tips |
| Japan | Not expected | Tipping can cause confusion |
Customs change, so check locally.
Tip before or after tax?
Etiquette guides usually suggest tipping on the pre-tax amount. Tipping on the total is more generous and simpler. The difference is small: on an 85 bill with 8% tax, 15% before tax is 12.75 and after tax is 13.77.
Service charge already included?
Check the bill for “service charge”, “gratuity” or “service included”. If it is there, an extra tip is not expected unless the service was exceptional.
Splitting unevenly
If some people ordered much more, split the bill by what each ordered first, then apply the tip percentage to each person’s share.
Other services
| Service | Common tip (US) |
|---|---|
| Taxi / ride-hailing | 10–20% |
| Hairdresser | 15–20% |
| Food delivery | 10–20% or a fixed amount |
| Hotel housekeeping | A small amount per night |
