Absence Rates Workload (Individual) Calculator Examples
Worked examples showing how expected absences affect annual capacity and planned workload for different working patterns.
These examples show how the same absence allowance can have different effects depending on contracted hours, work patterns, and workload targets. All results are planning estimates based on average hours per working day.

The 1,000-hour workload requires about 103.4% of available capacity, creating an estimated 32.5-hour shortfall.

Estimated annual capacity is 1,395 hours, and the workload uses about 89.6% of it.
How to Read Your Results
Available annual workload capacity is the estimated annual hours remaining after the absence allowance.
Absence rate measures absence days against scheduled workdays, not against calendar days.
Hours lost to absence convert absence days into time using the person's average hours per normal workday.
A positive capacity-after-workload result indicates estimated hours remaining; a negative result indicates an estimated shortfall.
Capacity needed for workload above 100% means planned demand is greater than the calculated available capacity.
Assumptions & Important Notes
- Each absence day is treated as an average scheduled workday.
- The examples do not separately deduct annual leave, public holidays, training, or meetings.
- Planned workload is assumed to be productive hours and not total paid hours.
- Actual absence and demand can vary during the year.

Frequently Asked Questions
How many absence days should I enter in a workload example?
Enter the number of expected scheduled workdays unavailable during the period you are planning for. Use an assumption that is appropriate for your internal planning approach.
Why does the part-time example show a shortfall with fewer absence days?
Part-time workers have fewer scheduled annual hours, so even a smaller number of absence days can materially reduce the capacity available for a high workload target.
Should planned workload equal available capacity exactly?
Not necessarily. A lower workload leaves room for work that is not included in the estimate and for variation, while the suitable buffer depends on the circumstances.
Can I use decimal absence days?
Yes, if your planning estimate includes part-day absences and the calculator accepts decimal values.
