How to use this tip calculator

Enter the bill, choose a percentage, and add tax only when you need it. The calculator can apply your tip before or after tax, then split the result between any number of people.

Simple formula: tip = bill × tip percentage. On an $80 bill, a 20% tip is $16.

Frequently asked questions

Should I tip on the pre-tax subtotal or after-tax total?

Both approaches are used. This calculator lets you choose the amount to use, so the calculation matches your preference or local custom.

Can I use a custom tip percentage?

Yes. Enter any non-negative percentage. The quick buttons are only common starting points.

How does the calculator split a tip?

It calculates the selected tip and total first, then divides both amounts by the number of people you enter.
