How to calculate absenteeism rate
This calculator finds absenteeism rate — the percentage of scheduled workdays an employee or workforce was absent — a standard HR metric for tracking attendance patterns.
How the calculation works
Absenteeism rate = (Absent workdays ÷ Available workdays) × 100.
Example
12 absent days out of 240 available workdays in a year: Absenteeism rate = (12 ÷ 240) × 100 = 5%.

Pro Tips for Absenteeism Rate
- Track absenteeism rate over consistent periods (monthly, quarterly) to spot trends rather than reacting to a single short period.
- Distinguish planned absences (approved vacation/PTO) from unplanned ones if your goal is specifically to monitor unplanned absenteeism.
Common Absenteeism Rate Mistakes to Avoid
- Including approved vacation and holidays in 'absent workdays' when the intent is to track unplanned absenteeism specifically, which conflates two very different things.
