Absence Rates Retention Calculator Examples
Worked examples show how absence rate, retention and estimated absence cost change across reporting scenarios.
These examples use the calculator's opening-headcount method. They illustrate how to calculate workforce metrics for a small team, a monthly department report, and a larger annual workforce review.

How to Read Your Results
Retention rate shows the share of employees who started the period and did not leave.
Absence rate shows the share of scheduled available workdays recorded as absence.
Estimated absence cost changes directly with the cost-per-day assumption.
Use the same reporting period and absence definitions when comparing results over time.
Review percentages alongside the actual number of employees and absence days.
Assumptions & Important Notes
- Each example uses opening employees as the denominator for retention and available workdays.
- All employees are assumed to have the same scheduled days for the reporting period.
- The cost estimate covers only the daily cost selected for the calculation.
- Absence categories are assumed to be applied consistently within each example.

Frequently Asked Questions
Can I calculate absence rate for a single month?
Yes. Enter scheduled workdays per employee for that month and use absence data from the same month.
Why can a small team have a volatile absence percentage?
The available-workday base is smaller, so each absence day has a larger percentage effect.
Should part-time employees use the same working-day input?
For best consistency, use an appropriate full-time-equivalent approach or calculate scheduled days that reflect the group's actual work pattern.
Does a 100% retention rate mean there were no new hires?
No. It only means no opening employees left during the period.
