Guidance, not law
Advice on this site reflects US custom, not law. Some employers prohibit accepting tips, and some bills already include a service charge. Follow posted policy and local law first. Every calculator here is an estimate built from compiled ranges — not a quote, not a wage, and not a bill.
When the answer is $0
If a tip is rude, already included, or forbidden, the honest result is $0. We won't invent a custom to fill the blank. You are always free to give more or less than the numbers shown.
