Absenteeism Rate Calculator
Find what percentage of scheduled work time was lost to absence.
How absenteeism rate works
Absenteeism rate is the share of scheduled work time lost to unplanned absence — a standard workforce-operations health metric used for staffing and cost planning.
Enter the total absent person-days and total scheduled person-days for the period (sum across your team or location). The calculator returns the absenteeism rate as a percentage.
Track this over time and by team or location — a rising trend is often an earlier and more actionable signal than the raw number itself.
The formula
Absenteeism rate = Absent person-days ÷ Scheduled person-days × 100
Divide the total absent person-days by the total scheduled person-days for the same period, then multiply by 100.
Worked example
15 absent person-days out of 300 scheduled person-days
15 ÷ 300 × 100 = 5% absenteeism rate.
Frequently asked questions
Should planned leave (vacation, holidays) be included?
Most absenteeism definitions count only unplanned absence — sick days, no-shows — and exclude scheduled vacation and holidays. Be explicit about which definition you're using.
What's a typical absenteeism rate?
It varies substantially by industry; general benchmarks commonly cited fall in the 2–5% range, but always compare to your own historical trend rather than a single external number.
How is a person-day counted for part-time staff?
Count a scheduled day as a person-day regardless of shift length, unless your organization has a more granular hours-based definition — apply whichever definition you choose consistently.
