Question 1

How much should I tip at a restaurant?

Accepted Answer

In the US, 15-20% is standard for sit-down restaurants. 15% for acceptable service, 18% for good service, and 20% or more for excellent service. For buffets, 10% is typical. Always tip on the pre-tax amount for accuracy.

Question 2

How do I calculate a 20% tip quickly in my head?

Accepted Answer

To calculate 20% quickly: move the decimal one place left (that's 10%), then double it. For example, on a $45 bill: 10% = $4.50, doubled = $9.00 tip. For 15%, calculate 10% and add half of that amount.

Question 3

Should I tip on the total bill including tax?

Accepted Answer

Technically, you should tip on the pre-tax subtotal since tax goes to the government, not the server. However, many people tip on the total for simplicity. Either way is acceptable - the difference is usually small.

Question 4

How do I split a bill with tip among multiple people?

Accepted Answer

Add your tip to the total bill, then divide by the number of people. This calculator does this automatically - enter the bill amount, tip percentage, and number of people to see each person's share.

Question 5

What's the tipping etiquette for takeout and delivery?

Accepted Answer

For delivery: 15-20% or at least $3-5 minimum. For takeout: tipping 10% or a few dollars is increasingly common but not mandatory. During busy times or for large/complex orders, tip more generously.
