🧾 Tip Calculator
Enter your bill, pick a tip percentage, and split it between everyone at the table.
How Tip Calculation Works
The tip amount is simply your bill total multiplied by the tip percentage you choose. If you're splitting the bill with friends or family, the total (bill + tip) is then divided evenly by the number of people.
Frequently Asked Questions
What is a standard tip percentage in the US?
For sit-down restaurant service, 15-20% of the pre-tax bill is standard, with 18-20% typical for good
service. For delivery or counter service, 10-15% (or a flat amount) is common.
Should I tip on the pre-tax or post-tax amount?
Tipping on the pre-tax subtotal is the more traditional convention, though many people simply tip on the
total shown on the receipt for simplicity — either is widely accepted.
Guide: understanding your result
- Tip = Bill × tip percentage. In the US, 15%–20% is customary for table service in restaurants.
- Many people tip on the pre-tax subtotal; check whether a service charge or automatic gratuity is already on the bill.
- Tipped workers may be paid a lower cash wage, with tips making up the difference to the minimum wage, so tips are a large part of their income.
