Formula

Absence % = (Days Absent / Scheduled Workdays) × 100

Attendance % = 100 − Absence %

How it works

The absence percentage (absenteeism rate) is the proportion of scheduled workdays lost to unplanned absences, expressed as a percentage. It is widely used in HR to benchmark workforce availability and identify absenteeism trends.

Scheduled workdays typically exclude weekends, public holidays, and approved leave (e.g., vacation, maternity leave); only unplanned or unapproved absences are counted in the numerator. Industry benchmarks for healthy absence rates generally fall between 1.5% and 3.5%.

Worked example

8 absent days out of 250 scheduled workdays

  1. Scheduled workdays in the period: 250.
  2. Unplanned absent days: 8.
  3. Absence % = (8 / 250) × 100 = 3.20%.
  4. Attendance rate = 100% − 3.20% = 96.80%.

Absence percentage = 3.20%; the employee was present 242 out of 250 scheduled days.
