Why measure the personnel turnover rate? 

If you are still not convinced about calculating the staff turnover rate, now we are going to give you some more reasons. And this measurement will serve as a barometer of stability and job satisfaction. In this sense, it provides you with valuable information about human resources management, helping to identify problems that may be causing employees to leave. 

high turnover rate can be an indicator of deficiencies in the work environment, dissatisfaction with company policies, or problems with compensation and benefits. Therefore, by analyzing this parameter you will be able to develop strategies to improve staff retention, optimize personnel selection processes, and ultimately, strengthen corporate culture and increase overall productivity. 

Calculation of personnel turnover rate 

Now, we are going to explain how to calculate the staff turnover rate. The general formula to calculate it is: 

R = (D / PE) * 100 


R represents the turnover rate. 

D is the number of personnel who left the company during the analyzed period. 

PE is the effective average of the period. In this case, PE is calculated by adding the number of employees at the beginning of the evaluation period and those at the end. The result is divided by two. 

When dividing D by PE, multiply it by 100 to obtain the result in percent. 

To interpret the results keep in mind the following:  

  • low turnover rate, generally less than 10% annually, can indicate good employee retention and a stable work environment. 
  • moderate turnover rate, between 10% and 20% annually, could be normal in industries with high demand for labour or in seasonal jobs. 
  • high turnover rategreater than 20% annually, can signal internal problems such as job dissatisfaction, lack of growth opportunities, or leadership issues that could require immediate attention. 

A practical case 

Suppose a company starts the year with 100 employees and at the end of the year has 90 employees. Additionally, during this time, 20 (D) workers left the company. The calculation would be the following: 

  1. First, we calculate the effective average, which in this case would be ( 100+90)/2. The result is PE = 95.  
  2. Then, we fill in the data of the formula, where R= (20/95) *100. When performing the first calculation it would be 0.21*100.  
  3. At the end of the calculation, we obtain a 21% turnover rate

Taking into account what was explained above, this is a high index, so the company should take action.
