Absence Rates Turnover Calculator FAQ
Answers to common questions about calculating employee absence, staff turnover, and estimated workforce costs.
This FAQ explains the calculator inputs, formulas, reporting-period choices, and the limits of absence and turnover cost estimates. Results are intended for general planning and internal reporting discussions.
General absence and turnover questions
Core definitions used when reviewing workforce attendance and retention.
What does the Absence Rates Turnover Calculator measure?
It estimates employee absence rate, employee turnover rate, absence cost, turnover cost, and their combined estimated cost for a chosen period.
What is an absence rate?
An absence rate is the proportion of available working days that were lost to employee absence, expressed as a percentage.
What is employee turnover rate?
Employee turnover rate is the number of employees who left during a period as a percentage of average headcount.
Can this calculator be used by a small business?
Yes. It can be used with any headcount of one or more, provided inputs relate to the same reporting period.
Inputs and reporting periods
How to choose and align the figures entered into the calculator.
What is average headcount?
Average headcount is the typical number of employees during the period. It may be based on opening and closing headcount or more frequent workforce records.
What should I enter for working days per employee?
Enter the possible working days for one employee in the period, excluding planned non-working days where that matches your reporting approach.
Should planned annual leave be counted as absence?
Usually it is excluded from absence reporting, but use the definition applied consistently within your organisation.
Can I calculate the results monthly, quarterly, or annually?
Yes. Use inputs from the same month, quarter, or year. Do not mix periods in one calculation.
How should internal transfers be treated?
Treatment depends on the purpose of your reporting. Decide whether a transfer counts as a leaver and apply that rule consistently over time.
Formula and cost questions
How the calculator produces percentages and estimated cost outputs.
How is total absence days calculated?
It is average headcount multiplied by average absence days per employee.
How is the absence rate calculated?
Total absence days are divided by total available working days, then multiplied by 100.
How is turnover rate calculated?
The number of leavers is divided by average headcount, then multiplied by 100.
What can be included in daily employee cost?
It can be an estimated daily employment cost, such as pay plus relevant employer costs, depending on your internal purpose and method.
What can be included in replacement cost per leaver?
Possible components include recruitment, administration, onboarding, training, temporary cover, and an estimated productivity effect.
Accuracy and interpretation
Important context for using the outputs responsibly.
Are the cost results actual costs?
No. They are estimates based entirely on the cost assumptions entered and may differ from actual financial outcomes.
Does the calculator explain the causes of absence or turnover?
No. It measures rates and estimated costs but does not identify causes, employee experience factors, or operational conditions.
Can I compare results between departments?
Yes, if departments use comparable definitions, time periods, working-day assumptions, and cost methods. Workforce mix may still affect comparisons.
Does a higher turnover rate always mean poor retention?
Not necessarily. The rate is a measure of workforce movement and should be interpreted with context such as planned restructuring, seasonal hiring, or contract end dates.
How is the employee absence rate calculated?
Divide total absence days by total available working days and multiply by 100.
