How the tip calculator works

The calculator starts from the bill as printed. If you tell it the sales tax rate baked into that figure, it backs out the pre-tax subtotal so you can choose to tip on either the full amount or just the food and service. It then applies your tip percentage, adds it to the bill, optionally rounds the total up to the next whole dollar, and divides by the size of your party.

The bar chart compares the grand total at five common tip rates so you can see, at a glance, what a few extra percentage points actually cost on this particular bill. On a small check the difference between 15 and 25 percent is often just a couple of dollars per person.

A quick example

Say the bill is 84.50 dollars, including 8 percent sales tax, split between two people at a 20 percent tip on the full amount. The tip works out to about 16.90 dollars, the total to roughly 101.40 dollars, and each person pays a little over 50 dollars. Switch the tip to the pre-tax subtotal and the gratuity drops by just over a dollar.

Things to keep in mind

Tipping customs differ widely around the world, and in some countries a service charge is already added to the bill, in which case an extra tip is optional. The U.S. Department of Labor explains how tips interact with wages in its tipped-employee fact sheet. When a group is settling up after a meal, our percentage calculator can help with any uneven splits.

Frequently asked questions

Should I tip on the pre-tax amount or the full bill?

Both are common and either is acceptable. Tipping on the pre-tax subtotal excludes sales tax from the calculation, so it is slightly cheaper and arguably fairer because tax is not a service the server provided. Many people simply tip on the total because it is easier to eyeball. This calculator lets you pick whichever base you prefer and shows the difference.

What is a standard tip percentage at a restaurant?

In the United States, 15 percent is often considered the floor for adequate sit-down service, 18 to 20 percent is the common range for good service, and 25 percent or more rewards exceptional service. Quick counter service, takeout and delivery tend to run lower. Norms vary by country, so the right number depends on local custom.

How does rounding up the total work?

When you turn on round up, the calculator raises the grand total to the next whole dollar and adds the difference to the tip. That keeps the math tidy for cash payers and nudges the gratuity slightly higher. The per-person figure is then taken from the rounded total, so everyone splits the same clean number.

How is the bill split between people?

After the tip is added, the calculator divides the grand total by the number of people to give an equal per-person share, and also shows how much of that share is tip. It assumes an even split. If diners ordered very different amounts, you may want to apportion the bill by each person's items first and then apply the tip percentage to each share.
