Question 1

What is the standard tip percentage at a restaurant?

Accepted Answer

In the US, 15–20% is the standard range for restaurant tips. 15% is acceptable for average service, 18–20% is typical for good service, and 25%+ for exceptional service.

Question 2

How is tip calculated?

Accepted Answer

Tip amount = bill total × tip percentage ÷ 100. The per-person cost = (bill total + tip) ÷ number of people. For example, a $120 bill with 20% tip = $24 tip, $144 total, $36 per person for 4 people.

Question 3

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

Accepted Answer

Both are acceptable. Tipping on the pre-tax amount is technically correct and slightly more common, but tipping on the total is fine and simpler to calculate.
