Employee turnover rate measures the share of your workforce that left during a reporting period, such as a month, quarter, or year. It includes voluntary exits, retirements, layoffs, and terminations. HR teams use turnover to track retention, hiring pressure, and culture health.
Separations are employees who left during the period. Average headcount smooths hiring and seasonal swings. Retention focuses on the starting cohort, while turnover compares exits to average workforce size.
Worked example
A company starts with 100 employees, ends with 110, and records 15 separations. Average headcount is 105. Turnover rate is 15 ÷ 105 × 100 = 14.29%. Retention rate is (100 − 15) ÷ 100 × 100 = 85.00%.
Frequently asked questions
What is a healthy employee turnover rate?
Healthy turnover varies by industry. Many employers target roughly 10% to 15% annual turnover, but retail and hospitality often run much higher, while specialized roles may run lower. Compare your rate to your sector and track trends over time.
What is the difference between voluntary and involuntary turnover?
Voluntary turnover happens when an employee chooses to leave, such as for a new job or retirement. Involuntary turnover happens when the employer ends the relationship through layoffs, restructuring, or performance-related separation.
How does retention rate differ from turnover rate?
Turnover divides separations by average headcount during the period. Retention measures how many employees from the starting headcount remained. Both metrics describe workforce stability but answer slightly different questions.
How can a company reduce turnover?
Common levers include competitive pay, clear career paths, manager training, workload balance, and listening to exit interview feedback. Tracking turnover by department helps pinpoint where retention problems concentrate.
