Definition – What is the meaning of “Absence Rate”?

Employee Absence Rate is the rate of worker absences to total full-time employment.

A high absence rate means that employees are frequently missing work. A low absence rate means that employees are often at work.

Formula – How to calculate Employee Absence Rate

Employee Absence Rate = (Number of Absence Days ÷ (Total Employees x Work Days)) x 100%


  • Number of Absence Days” is the number of days any employee is absent from the business for any reason.
  • Total Employees” is the total number of employees in the business.
  • Work Days” is the number of days to measure the absence rate (some people prefer to measure absence rate over years, others prefer to target a specific month or week).


A company has a total of 150 absence days among 300 employees over 22 work days.

Employee Absence Rate = (150 ÷ (300 x 22)) x 100% = (150 ÷ 6600) x 100% = 0.02272 x 100% = 2.27%

Therefore, this company has an EAR of 2.27%.
