Enter the number of days missed and the number of possible days to be attended into the Absence Rate Calculator. The calculator will evaluate the Absence Rate. 

Absence Rate Formula

The following two example problems outline the steps and information needed to calculate the Absence Rate.

ABR = DM / TD * 100

  • Where ABR is the Absence Rate (%)
  • DM is the number of days missed 
  • TD is the number of possible days to be attended 

How to Calculate Absence Rate?

The following example problems outline how to calculate Absence Rate.

Example Problem #1:

  1. First, determine the number of days missed. 
    • The number of days missed is given as: 5.
  2. Next, determine the number of possible days to be attended. 
    • The number of possible days to be attended is provided as: 50.
  3. Finally, calculate the Absence Rate using the equation above: 

ABR = DM / TD * 100

The values provided above are inserted into the equation below and computed.

ABR = 5 / 50 * 100 = 10.00 (%)


Example Problem #2: 

For this problem, the variables required are provided below:

number of days missed = 6

number of possible days to be attended = 30

Test your knowledge using the equation and check your answer with the calculator..

ABR = DM / TD * 100 = ?
