How to Read Your Results
Total absence days estimate the combined annual workdays lost across the average workforce.
Absence hours use the standard daily hours derived from the weekly schedule entered.
The absence rate compares lost days with scheduled workdays, making results easier to compare across workforce sizes.
FTE workload lost is annual capacity, not necessarily the number of people needed for cover.
Average daily staffing gap uses the same annual FTE measure and should not be treated as a peak-gap forecast.
Assumptions & Important Notes
- All employees are represented by one average work pattern.
- The absence average applies consistently across the workforce.
- The examples use annual totals and do not model the timing of absence.

Frequently Asked Questions
Can I use this calculator for a part-time workforce?
Yes, as a broad estimate if the entered average working days and hours fairly represent the workforce. Separate groups may be clearer where schedules differ widely.
Why can two teams have the same absence rate but different hours lost?
Their daily hours can differ. The rate uses days relative to scheduled days, while hours also depend on the working pattern.
Should I calculate each department separately?
Separate calculations can be useful when departments have different schedules, roles or absence patterns.
