Summary
Employee turnover rate measures the percentage of workers who leave an organization during a given period. HR teams track it monthly and annualize the figure to compare across quarters, benchmark against industry norms, and estimate recruitment costs. This calculator uses the standard SHRM formula: separations divided by average headcount, multiplied by 100.
