How it is calculated

Absenteeism rate = days absent ÷ (employees × working days in the period) × 100. Average per employee = days absent ÷ employees.

Example

Inputs: Total days absent = 30 days, Employees = 25, Working days in the period = 22 days. Result: Absenteeism rate: 5.45%; Average days absent per employee: 1.2 days; Available workdays: 550 days.

Limits and caveats

  • Do not count approved annual leave as absence; it is planned time off.
  • Decide whether sick leave counts as absence and keep it the same each period.

Questions about this tool

How do I work out absenteeism for a month?

Add up days absent for everyone and divide by employees × working days. 30 days across 25 people and 22 days gives 5.45%.

How do I enter half days?

Enter them as fractions: half a day absent is 0.5.

Can I use hours instead of days?

Yes. Enter hours absent in place of days and each person's available hours in place of working days; the rate stays correct.
