Calculating turnover: a strategic necessity

When it comes to human resources management, understanding turnover goes far beyond simple statistics. It is a strategic indicator that measures how often employees leave a company and positions are filled by new hires. Calculating turnover allows you to quantify the financial, emotional, and operational impact of these departures.

Methods for calculating turnover

1. Basic formula:

The basic calculation of turnover is done by dividing the number of departures during a given period by the total number of employees, then multiplying the result by 100 to obtain a percentage.

Onboarding as a preventive solution

An essential aspect that is often overlooked when calculating turnover is onboarding, or the integration of new employees. A solid onboarding process facilitates the adaptation of new talent, reduces the stress of adjustment, and strengthens their commitment to the company.

Key steps for successful onboarding:

  • Warm welcome: Create a positive first impression by welcoming new employees in a warm and inclusive manner.

  • Structured training: Provide clear, structured training to help newcomers understand their responsibilities and integrate quickly.

  • Mentoring: Encourage mentoring by pairing new employees with experienced colleagues to facilitate their integration.

  • Ongoing feedback: Provide regular feedback to assess new employees' progress and adjust the onboarding process as needed.

Investing in effective onboarding not only helps reduce turnover but also increases employee satisfaction and productivity.

In fact, calculating turnover is much more than a simple statistical analysis. It is a strategic approach that provides visibility into organizational health and guides the implementation of preventive measures. Effectively integrating onboarding into this equation strengthens talent retention, creating an environment where employees thrive and contribute positively to the growth of the company.
