Absence Rates Workload (Individual) Calculator FAQ
Answers to common questions about individual absence rates, annual capacity, workload utilisation, and calculation assumptions.
This FAQ explains the inputs, results, and boundaries of an individual absence workload calculation. The calculator is intended for general planning estimates and should be used alongside relevant operational information.
General questions
Basic questions about what the calculator estimates and who can use it.
What does the Absence Rates Workload (Individual) Calculator do?
It estimates an individual's annual working capacity after expected absence days and compares that capacity with a planned annual workload.
Who is this calculator for?
It can be used for general workload planning for an individual employee, contractor, or role where weekly hours and normal workdays are known.
Can it be used for full-time and part-time staff?
Yes. Enter the working pattern, contracted hours, absence allowance, and workload that apply to the individual.
Is the result a prediction of actual absence?
No. It is an estimate based on the absence days entered and may differ from actual absence.
Inputs and calculation method
Questions about hours, workdays, absence days, and the formulas used.
How are annual scheduled hours calculated?
Annual scheduled hours equal contracted weekly hours multiplied by working weeks per year.
How are absence days converted into lost hours?
The calculator divides weekly hours by working days per week, then multiplies the resulting average daily hours by absence days.
How is the absence rate calculated?
It divides absence days by annual scheduled workdays and multiplies the result by 100.
What should I enter for working weeks per year?
Enter the number of contracted weeks you want the calculation to cover before deducting the absence days entered. Keep your treatment of leave and shutdown periods consistent.
Can I enter half-days of absence?
Yes, where the calculator permits decimal absence days. They are converted using the same average daily hours figure.
Understanding the results
Questions about capacity, utilisation, and workload shortfalls.
What is available annual workload capacity?
It is scheduled annual hours less the estimated hours lost to expected absence.
What does capacity needed for workload show?
It shows planned workload as a percentage of absence-adjusted annual capacity.
What does 100% workload utilisation mean?
It means the planned workload equals the estimated capacity remaining after absence, leaving no calculated hours spare.
What does a negative remaining-capacity figure mean?
It means planned workload is greater than calculated capacity. The magnitude shows the estimated number of hours by which it exceeds capacity.
Why might a positive remaining-capacity figure still be difficult to use?
The hours may be needed for activity not included in the workload figure, or they may not be available when demand occurs.
Assumptions and use
Questions about factors that may need separate consideration.
Should annual leave be entered as absence?
Usually it is planned separately. Include it only if your approach treats it as unavailable time and it has not already been reflected in working weeks or workload.
Does the calculator include overtime?
No. It uses the contracted weekly hours entered unless you deliberately include an alternative planning assumption in those inputs.
Does it account for public holidays, training, or meetings?
Not automatically. Consider these separately unless they are already reflected in working weeks or planned workload hours.
Can this result be used as the only basis for staffing decisions?
No. It is a general planning estimate and does not capture all operational, contractual, or individual factors.
How are absence days converted into lost hours?
The calculator divides weekly hours by working days per week, then multiplies the resulting average daily hours by absence days.
