Absence Rates Retention (Annual) Calculator Examples
Worked examples showing how to estimate annual employee absence rates, absence days per employee and retention rates.
These examples use the calculator's annual method: average opening and closing headcount estimates workforce capacity, while ending headcount less hires estimates retained opening employees. Use the same reporting definitions across each example or reporting period.

How to Read Your Results
The annual absence rate shows recorded absence days as a percentage of estimated available working days.
Absence days per employee converts the total absence figure into an easier-to-read average across the estimated workforce.
The retention rate is an estimate of opening employees still present at year end, not a replacement for employee-level movement data.
Compare results across periods only when the headcount, working-day and absence-category definitions remain consistent.
Review the percentages with workforce context such as restructures, seasonal staffing or changes in reporting practice.
Assumptions & Important Notes
- Each example applies one planned working-day figure to all employees.
- Absence totals exclude or include leave categories consistently within the example.
- Hires are all recorded within the same annual reporting period.
- The midpoint of starting and ending headcount is used as the average workforce estimate.

Frequently Asked Questions
Can I use these examples for a department instead of a whole company?
Yes, if the department's headcount, hires, working days and absence days are measured using the same reporting basis.
Why does a growing team use average headcount?
The team was not at its opening or closing size for the entire year. The midpoint provides a simple estimate of annual workforce capacity.
What does 3.3 absence days per employee mean?
It means total recorded absence divided by average headcount equals 3.3 days. It is an overall average, not necessarily each individual's absence.
Can two teams have the same absence rate but different absence days per employee?
If they use the same working days per employee, the measures move together proportionally. Different working-day allowances can produce different relationships.
