What is a Buffet Tip?

A buffet tip is the gratuity (money) left for the staff who provided service during a buffet meal. In this calculator, the tip is calculated as a percentage of the buffet bill: Tip = Bill ร— Tip Rate. The tip rate is entered as a decimal (for example, 0.15 for a 15% tip).

How to Calculate Buffet Tip?

The following steps outline how to calculate the Buffet Tip using the formula T = B ร— r.


  1. First, determine the total buffet bill amount ($). 
  2. Next, determine the tip rate (decimal). 
  3. Next, gather the formula from above = T = B ร— r.
  4. Finally, calculate the tip amount (gratuity).
  5. After inserting the variables and calculating the result, check your answer with a calculator.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total buffet bill amount ($) = 100

tip rate (decimal) = 0.15

total tip amount ($) = T = B ร— r = 100 ร— 0.15 = 15
