Absence Rates Capacity (Individual) Calculator Examples
Worked examples showing how leave, sickness, training and work schedules affect an individual’s annual available capacity.
These examples show how the calculator converts scheduled workdays and expected absences into available working days, productive hours and an effective capacity rate. They are planning illustrations rather than predictions of actual availability.

How to Read Your Results
Available working days are the scheduled days left after the entered absence categories are deducted.
Available productive hours convert remaining days into time using the stated daily hours.
The absence rate is the percentage of scheduled days deducted as leave, sickness, training and other non-working time.
The effective capacity rate is the percentage of scheduled annual time remaining for normal duties.
Compare people with different schedules using rates, and use hours when estimating total time available.
Assumptions & Important Notes
- All absence values are expected annual working-day amounts.
- Absence categories do not overlap.
- Hours per workday remain constant throughout the year.
- The examples estimate availability only and do not measure output or performance.

Frequently Asked Questions
How can I estimate an employee’s annual available hours?
Estimate available workdays after absences, then multiply those days by the person’s normal hours per workday.
Can I compare full-time and part-time individual capacity?
Yes. Compare hours to see total time available and compare capacity rates to see the proportion of each schedule remaining.
Should training days reduce productive capacity?
They reduce capacity for normal duties when training occurs away from those duties. Whether to count them depends on the planning purpose.
What if sickness absence is unknown?
Use a clearly labelled planning estimate, such as a historical average, and review the result under more than one scenario.
