Turn missed days into a cleaner percentage
A percentage can be easier to compare across teams or periods than a raw absence count alone.

Absenteeism Rate Calculator
Estimate absenteeism rate and attendance percentage from missed workdays and scheduled workdays.
Why this page exists
Attendance metrics are easier to read when missed days are translated into a clear rate instead of left as a raw count. This calculator helps visitors estimate absenteeism rate from total missed workdays and scheduled workdays, while also showing the matching attendance percentage.

Planning note
Last updated April 11, 2026. Use this tool to compare scenarios and plan ahead, then confirm important details with the lender, employer, insurer, contractor, or other qualified provider involved in the final decision.
How it works
What the calculator is doing
Enter the total missed workdays and the total scheduled workdays for the period.
The calculator divides missed days by scheduled days to estimate absenteeism rate.
It also converts the result into an attendance percentage for an easy complementary view.
Understanding your result
Absenteeism is easier to interpret when the rate and attendance percentage are shown together, because one explains the share missed while the other shows how much of the schedule was still covered. It is still a simple planning metric rather than a full HR report.

FAQ
Common questions
How is absenteeism rate calculated?
The calculator divides total missed workdays by total scheduled workdays, then multiplies by 100 to show the result as a percentage.
Why show attendance percentage too?
Because it gives a complementary view of the same period by showing how much of the schedule was still worked or covered.
Can missed days exceed scheduled workdays here?
No. The calculator caps missed days at the scheduled total because absences cannot exceed the full scheduled period.
