The Tip Calculator calculates tip amounts for various percentages of the service cost and shows a total amount that includes the tip. A tip between 15% to 20% of the before-tax meal price is typically expected in the U.S. and Canada. In Europe, it is between 10% and 15% of the bill before tax.

In the U.S. or any other country where tipping is expected, gratuity may be automatically applied to the bill amount depending on the restaurant or the number of patrons at a table.
