Many restaurants charge a mandatory service charge for parties of 6 or more. This is not a tip — it's a fee that may or may not go to the staff. You can still add an additional voluntary tip on top.

About This Calculator

What it does

Compares a mandatory service charge (often 18–25% auto-added) with a voluntary tip, and explains the legal and tax distinction. Example: a 20% auto-gratuity for a party of 8 goes to the house pool by law—you generally don't add a second tip unless service was exceptional.

Frequently asked questions

Is a service charge the same as a tip?

No. A service charge is a mandatory fee (typically 18–25%) that legally belongs to the business and is pooled; a tip is voluntary and goes to staff, with different IRS treatment.

Should I tip if there is a service charge?

Usually not, unless service was exceptional. Many restaurants auto-add 18–20% for large groups—check the menu before adding more.
