Annual Absence Rate Sensitivity Analysis Calculator FAQ
Answers to common questions about annual absence rates, scenario ranges, lost workdays, and estimated absence costs.
This FAQ explains the calculator inputs, calculation method, assumptions, and ways to interpret lower, expected, and higher annual absence scenarios.
General annual absence questions
Basic definitions and uses of annual absence-rate estimates.
What is an annual absence rate?
It is the percentage of scheduled working time estimated to be lost to absence over a year.
What does this calculator estimate?
It estimates total absence days and absence-related costs for lower, expected, and higher annual absence-rate scenarios.
Who can use an absence sensitivity analysis?
It can be used for general workforce planning, budgeting discussions, and internal scenario modelling.
Is the result an actual absence forecast?
No. It is a simplified estimate based on the inputs and assumptions selected.
Inputs and calculation method
How the calculator turns workforce inputs into annual scenarios.
How are total scheduled workdays calculated?
The calculator multiplies the number of employees by working days per employee per year.
How are expected absence days calculated?
Total scheduled workdays are multiplied by the expected absence rate divided by 100.
What is the sensitivity range?
It is the number of percentage points added to and subtracted from the expected absence rate.
How is the effective daily cost calculated?
Average daily cost is multiplied by the cost coverage rate divided by 100.
What is the annual cost range?
It is the higher-scenario annual cost minus the lower-scenario annual cost.
Accuracy and assumptions
Factors that can cause actual experience to differ from the estimate.
Does the calculator include every cost of absence?
No. It includes only the daily cost and coverage share entered, and may not capture all operational effects.
Why might actual costs differ from the estimate?
Actual costs can vary with absence timing, role coverage, overtime, pay arrangements, productivity effects, and other local factors.
Does the model account for different absence types?
No. It uses one combined annual absence rate and one average daily cost.
Are results suitable for employment or financial decisions?
Results are educational planning estimates and should not be treated as employment, financial, legal, or professional advice.
Using the results
How to interpret and apply the scenario outputs.
What does a lower-scenario cost mean?
It is the estimated annual cost if the absence rate is lower than expected by the chosen sensitivity range.
What does a higher-scenario cost mean?
It is the estimated annual cost if the absence rate is higher than expected by the chosen sensitivity range.
Can I set cost coverage to less than 100%?
Yes. A lower rate can model cases where only part of the estimated daily cost is considered measurable.
Should I use percentage points or percentages for the range?
Use percentage points. For example, 4% with a 1-point range gives 3% and 5%.
How is annual absence cost calculated?
The calculator multiplies scheduled workdays by the absence rate and then by the effective cost per absent day.
