Absence Rates Retention Calculator FAQ
Answers to common questions about calculating employee absence rates, retention, workdays and absence costs.
This FAQ explains what the calculator measures, which inputs it uses, and how to interpret results consistently. Figures are estimates for workforce reporting and should be reviewed alongside underlying HR records.
General calculator questions
Basic questions about the calculator's purpose and reporting periods.
What does the Absence Rates Retention Calculator measure?
It estimates employee retention, absence rate, available working days, and direct absence cost for a chosen reporting period.
Can this calculator be used for annual, quarterly, or monthly reports?
Yes. Use inputs that all relate to the same reporting period.
Is this a turnover calculator?
It calculates retention from opening employees and leavers. Turnover can be reported differently depending on the method used.
What is the difference between absence rate and attendance rate?
Absence rate is the percentage of scheduled time lost to absence. Attendance rate is commonly the remaining scheduled time, but definitions can vary.
Retention calculation questions
How the calculator treats opening employees and leavers.
Why does retention use the opening headcount?
The calculation is designed to show what proportion of employees present at the start remained during the period.
What happens if there are no leavers?
Retention is 100%, provided the opening headcount is greater than zero.
Should temporary staff be included?
Include them only if they are part of the workforce population you are tracking, and apply that choice consistently.
Do new employees increase the retention rate?
No. New hires do not change the retained count because they were not in the opening workforce.
Absence and cost inputs
Questions about days, categories and cost estimates.
What should be included in total absence days?
Include only the absence categories your organisation has chosen to monitor, using the same definition every reporting period.
Should planned leave be included as absence?
That depends on your internal reporting definition. The key is to use the same treatment when comparing periods.
What does cost per absence day represent?
It is your chosen estimate of direct cost for one lost workday, such as relevant pay or cover costs.
Does estimated absence cost include lost productivity?
Not automatically. It only includes what is captured in your selected cost per absence day.
Accuracy and interpretation
How to use calculated figures appropriately.
Why might the result differ from another HR report?
Reports may use average headcount, full-time equivalents, different absence categories, or different time periods.
Can I compare departments using this calculator?
Yes, if each department uses comparable scheduled-day calculations, staff populations, and absence definitions.
Does a high absence rate identify the cause?
No. The rate measures lost scheduled time; supporting records are needed to understand causes and patterns.
Are these results suitable for formal employment decisions?
The calculator provides estimates for reporting. Use appropriate internal processes and records for employment-related decisions.
How is employee absence rate calculated?
Total absence days are divided by available working days, then multiplied by 100.
