Absence Rates Productivity (Annual) Calculator Examples
Worked annual absence-rate examples showing how workforce absence can affect lost hours, FTE capacity and estimated labour value.
These examples use different workforce sizes, work patterns, absence rates and recovery assumptions. They illustrate how the same absence rate can produce very different capacity and cost estimates when hours, recovery and labour costs change.

How to Read Your Results
Annual absence days show the total scheduled workdays estimated to be lost across the workforce.
Lost productive hours exclude the absence time assumed to be recovered through cover, overtime or rescheduling.
FTE capacity lost translates unrecovered hours into annual full-time workload equivalents, not headcount reductions.
Estimated annual productivity cost is a labour-value proxy and is not a complete measure of business impact.
Compare periods or teams only when the work-pattern, recovery and hourly-cost assumptions are consistent.
Assumptions & Important Notes
- Each scenario applies a single average work pattern and hourly cost to the workforce in scope.
- The productivity-impact percentage is an estimate of unrecovered time rather than a measured service or revenue loss.
- Dollar values are illustrative and use the specified hourly labour-cost assumption.
- Results are annual estimates and do not reflect seasonal peaks or the distribution of absences.

Frequently Asked Questions
Can I use these examples for a department?
Yes. Replace the workforce inputs with the employee count, schedule, absence rate and cost assumptions for that department.
Why can two teams with the same absence rate have different costs?
Their workforce size, hours, recovery level and hourly labour cost may differ, changing total affected and unrecovered time.
What does a high productivity-impact percentage mean?
It means a larger share of absence time is assumed to remain unrecovered after cover or rescheduling.
Are the example cost figures direct cash costs?
No. They are estimates of the labour-value equivalent of unrecovered productive hours.
