Absenteeism Rate: Meaning and Purpose
The absenteeism rate shows what share of scheduled working days are lost to unplanned absence. It helps HR see the impact on productivity and cost.
Factors That Affect the Result
- Number of employees
- Working days in the period
- Days of unplanned absence
- Which leaves to exclude, such as planned leave and holidays
- Trends by team or day of the week
How the Absenteeism Rate Is Calculated
Available days = Employees × Working days in the period
Absenteeism rate % = Absent days ÷ Available days × 100
Worked example
With 100 employees, 22 working days and 66 days of unplanned absence, the rate is 66 ÷ 2,200 × 100 = 3%.

Compliance note: Define which absences count and apply the same definition each month.
Frequently Asked Questions
What is a normal absenteeism rate?
Many organisations see between 2% and 4%. A sustained rise above your own baseline is more important than any benchmark.
Should planned leave be counted?
Usually not. Most employers measure unplanned absence only, such as sick leave and absence without notice.
How can attendance software help?
It gives accurate daily data, flags patterns by team and weekday, and cuts the time spent on regularisation and manual muster rolls.
What is the Bradford Factor?
It is a scoring method that weighs frequent short absences more heavily than a single long absence.
