Employee retention refers to an organization’s ability to successfully retain its employees. While employers strive to keep top performers, employee turnover is expected and natural for any organization.
While retention and turnover rates are helpful to understand, employers can also track and analyze the following factors:
- Turnover rate categorized as voluntary or involuntary
- Turnover rate due to internal promotions or transfers
- Positions opened
- Positions filled
- Average employee tenure

Benchmarking helps organizations capture data and continually measure their performance. Employee retention can be measured weekly, monthly, quarterly or annually to actively monitor and benchmark retention efforts. Organizations can use these metrics to evaluate their own performance.
Retention Rate
Employee retention refers to the ability of an organization to retain its employees.
Employee Rate = (Total number of employees – Total number of employees who left / Total number of employees) x 100
Turnover Rate
Another key metric for organizations to measure and track is the employee turnover rate. An organization’s turnover rate measures the number of employees who leave during a specific time period, such as a month or year.
Employee Turnover Rate = (Number of employees who left / Average number of employees) x 100
To calculate the average number of employees, simply add the number of employees at the beginning of the time period you’re measuring and the number of employees at the end of that same period. Then, divide by two.
