Question 1

What percentage should you tip at a restaurant?

Accepted Answer

In the United States, the standard tip at a sit-down restaurant is 15–20% of the pre-tax bill. A 15% tip is considered the minimum for adequate service, 18% is common for good service, and 20% or more is customary for excellent service. For buffet-style dining or counter service, 10% or a small dollar amount is typical.

Question 2

How can you calculate a tip quickly in your head?

Accepted Answer

An easy mental math trick: to find 10% of the bill, simply move the decimal point one place to the left. For a 20% tip, double that number. For a 15% tip, take the 10% figure and add half of it. For example, on a $48 bill, 10% is $4.80, so a 20% tip is $9.60 and a 15% tip is $4.80 + $2.40 = $7.20.

Question 3

Should you tip on the pre-tax or post-tax amount?

Accepted Answer

Tipping etiquette in the US generally considers tipping on the pre-tax subtotal to be correct, since the service is based on the food and drink ordered rather than the tax added by the government. However, tipping on the post-tax total is also widely practiced and results in a slightly larger tip. The difference is usually small, so either approach is acceptable.

Question 4

How much should you tip at a bar?

Accepted Answer

At a bar, the standard practice in the US is to tip $1–2 per drink for simple orders like a beer or a well drink, or 15–20% of the total tab for more complex cocktails or table service. Running a tab and tipping at the end as a percentage is common when ordering multiple rounds. Tipping per drink is more typical when ordering individually at the bar.

Question 5

How do you split a bill evenly between multiple people?

Accepted Answer

To split a bill evenly, first add the tip to the total bill to get the grand total, then divide that amount by the number of people. For example, if the bill is $120 and you add an 18% tip ($21.60), the grand total is $141.60. Split between 4 people, each person owes $141.60 ÷ 4 = $35.40.
