How Do I Calculate Staff Turnover As a Percentage?
Divide the number of employees who left the organization during that specified time period by the average number of employees employed during the same period of time to find the employee turnover rate percentage. The lower the percentage, the better an organization is at retaining employees.
Establish a time frame
Determine the time frame for which you want to calculate the staff turnover. You may calculate by quarter, by year or by some other time frame.
Consider the average number of employees
Determine the average number of employees employed during the specified time frame was. For example, if an organization had 19 employees for six months and 21 employees for six months, the average number of employees for the year would be 20.
Determine how many employees are no longer employed
Calculate how many employees from the measured period of time are no longer employed in the organization. This could be for any reason, including termination from employment or employees choosing to leave for another job. For the sake of this example, assume the number is five.
Calculate the percentage
Divide the number of employees who are no longer employed by the average number of employees during the established time period to get the percentage. In this example, five divided by 20 equals 0.25. So the staff turnover as a percentage is 25 percent.
