Absence Rates Workload Calculator FAQ
Answers to common questions about absence rates, lost capacity, available employees, and FTE cover estimates.
This FAQ explains what the calculator measures, which inputs to use, and why estimated absence-related cover needs can differ from actual operational staffing needs.
Using the calculator
Questions about the inputs and planning periods.
What is an absence rate?
An absence rate is the percentage of planned work time or scheduled workdays that is lost because employees are absent.
What employee number should I enter?
Use the average number of employees expected to be scheduled during the selected period, rather than a peak headcount.
Can I calculate monthly absence capacity?
Yes. Enter monthly scheduled working days per employee and use the average workforce for that month.
Should working days include weekends?
Only include days that are scheduled working days for the employees and period being assessed.
Understanding the results
Questions about capacity, lost days, and cover outputs.
What do estimated workdays lost mean?
They are the planned employee workdays estimated to be unavailable after applying the absence rate.
What are available workdays?
They are total scheduled workdays minus estimated lost workdays.
What does average available employees mean?
It is the average workforce capacity remaining after the absence percentage is applied; it is not a daily attendance prediction.
What does estimated cover needed mean?
It is the full-time-equivalent capacity that matches the estimated lost workdays across the selected period.
Accuracy and assumptions
Questions about how to interpret an estimate responsibly.
Is the calculator a forecast of actual absences?
No. It applies an entered rate to planned capacity, so the result is a planning estimate.
Why might actual cover needs be higher?
Absence can affect critical shifts or specialist roles, and available cover may not be interchangeable with absent employees.
Does the calculator account for skill mix?
No. It treats capacity as equivalent workdays and does not assess role-specific skills or qualifications.
Does it include holidays, overtime, or vacancies?
No. Reflect these factors separately in the working-day input or broader workforce plan if needed.
Comparing scenarios
Questions about using results in workforce planning.
How can I test a higher absence scenario?
Keep the workforce and planned days the same, then rerun the calculation with a higher absence rate.
Can I compare teams with different schedules?
Yes, but calculate each team separately when their working days, hours, roles, or absence patterns differ.
Does a lower absence rate always remove the need for cover?
Not necessarily. The operational impact depends on when absences occur and which roles are affected.
How are workdays lost to absence calculated?
Total scheduled workdays are multiplied by the absence rate divided by 100.
