Employee Turnover Rate
The percentage of the average employee population that left during a defined period under the selected departure scope.
Business question
What share of the average employee population left during the reporting period?
Formula
Employee turnover rate = (employee departures in the period ÷ average employee headcount during the period) × 100.
Calculation notes
Define the employee population, departure scope, and average-headcount method, such as opening and closing headcount or more frequent observations.
Edge-case guidance
Separate planned seasonal staffing changes, internal transfers, and different departure types where they have different management implications.
Required data

Interpretation
Use the measure to see workforce movement and investigate voluntary or involuntary departures, tenure, role, and business context.
Caution
Turnover should be segmented by departure type, role, tenure, and seasonality. A lower rate is not automatically better if performance issues are not addressed.
Implementation recommendation
Keep a consistent headcount and departure definition, then pair the rate with absence, workload, and service-quality signals.
Target guidance
Set the first target from a comparable historical baseline for employee turnover rate, then adjust it for strategy, capacity, seasonality, data quality, and relevant market or regulatory context. Review the direction with the accountable business owner rather than treating any external benchmark as universal.
