Employee Turnover Calculator
Estimate employee departures as a proportion of average headcount over a chosen reporting period.
How to use this calculator
- Enter departures during a stated period and average headcount for that same period.
- Review the worked example for employee turnover calculator and compare the inputs with your own units.
- Change one assumption at a time and recalculate if you need a second scenario.
Turnover rate
Employee turnover rate = departures ÷ average headcount × 100.
- The result depends on whether an organisation uses average headcount, period-start headcount, or another reporting convention.
- The result is calculated from the values entered; the page does not independently verify assumptions, data quality or real-world suitability.
Worked examples
An annual team measure
Six departures occur during a year when average headcount is 75.
6 ÷ 75 × 100 = 8%
The estimated turnover rate is 8% for the period.
Understanding the result
Using the same denominator convention makes comparisons over time more meaningful.
The aggregate rate does not explain reasons for departure, role mix, seasonality or whether departures were voluntary.
Important notes
Label the reporting period and denominator in any report.
Displayed figures are rounded for readability. Preserve more precision during intermediate calculations and verify the labels and units before using the estimate.
