6. Turn over rate (voluntary/involuntary)
The turnover rate refers to the percentage of staff that leave a company within a specific period. Employee turnover is the act of replacing staff that have left the establishment. A high rate means a company is significantly hiring and rehiring, while a low turn-over rate shows employees are staying in their positions for longer.
The turn-over rate and retention rate are two sides of the same coin as they measure how well and how poorly a company does at keeping their employees positioned within the company.
Your business can use the turnover formula to determine the total turn-over rate:
(number of employees that have left in a period / average number of employees in the same period) x 100 = Turnover rate %
In addition to the total turn-over rate, this metric can further be divided into two parts: voluntary separation from the company and involuntary separation from the company. Voluntary separation refers to employees who choose to leave the company versus being laid off, fired, or those that retire.
(number of voluntary separations in a period / average number of employees in the same period) x 100 = voluntary turnover rate %
(number of involuntary separations in a period / average number of employees in the same period) x 100 = involuntary turnover rate %
