Turnover measures how a company\u2019s workforce renews over time. Learn how to calculate it (INSEE and operational methods), the average rate in France (15%), its main causes, its direct and hidden costs, and the key levers to reduce it: onboarding, hands-on management and listening to your employees.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n

Employee turnover: definition, costs and areas for improvement<\/span><\/h2>\n

Employee turnover measures how much your workforce changes over a given period, usually a calendar year. It covers departures, including resignations, dismissals and contracts coming to an end, as well as new hires joining the company. A controlled level of turnover is a normal part of organizational life. High turnover, however, has a lasting impact on performance, team cohesion and the company\u2019s finances.<\/p>\n

Identifying its causes, knowing how to calculate your turnover rate and understanding its true cost are the first steps toward taking effective action.<\/p>\n

What is employee turnover? Definition and HR challenges<\/span><\/h2>\n

Employee turnover refers to the rate at which an organization\u2019s workforce is renewed over a given period. The higher the rate, the more frequent the staff movements. The lower the rate, the more stable the teams over time.<\/p>\n

This figure is never neutral. It reflects how attractive your company is, the quality of its management, the working atmosphere and, ultimately, the overall health of your organization. Tracking it regularly helps you anticipate HR issues before they become critical.<\/p>\n

The term comes from the verb \u201cto turn over\u201d, meaning to renew or replace. Depending on the source, you will also see it called staff turnover, labor turnover or employee turnover rate. All of these describe exactly the same reality: the number of employees joining and leaving your company over a given period. The choice of term mostly depends on context: \u201cturnover\u201d in a leadership meeting, \u201clabor turnover\u201d in official HR reporting.<\/p>\n

Voluntary vs involuntary turnover, internal vs external turnover<\/span><\/h3>\n

Not every departure tells the same story, and this distinction completely changes the diagnosis.<\/p>\n

Voluntary turnover:<\/strong> the employee chooses to leave, through a resignation, a mutual termination agreement they initiated, or early retirement. A high rate here should raise a red flag. It often points to a retention problem or a deteriorating social climate<\/a>.<\/p>\n

Involuntary turnover:<\/strong> the company decides on the departure, through a redundancy, a dismissal for misconduct, or the employer ending a probationary period. This tends to signal a recruitment problem or a poor match between candidate and role.<\/p>\n

Internal turnover:<\/strong> an employee changes role or department within the company, with no actual departure from the workforce.<\/p>\n

External turnover:<\/strong> the employee leaves permanently to pursue their career elsewhere.<\/p>\n

Confusing these categories, or being unable to tell them apart, means missing the right diagnosis. A company with 20% turnover driven mainly by retirements faces a very different problem from one with 20% turnover driven by senior managers resigning.<\/p>\n

How do you calculate the turnover rate?<\/span><\/h2>\n

The turnover rate formula is simple. The real challenge lies in knowing which departures to include and which method to use. There are two approaches.<\/p>\n

The turnover rate formula: INSEE method vs operational method<\/span><\/h3>\n

The INSEE method is the benchmark used by INSEE (France\u2019s national statistics institute) and DARES (the French Ministry of Labor\u2019s research department) in their publications on workforce movements. It measures the overall intensity of inflows and outflows over the period, and is calculated as follows:<\/p>\n

Turnover rate = [(number of hires + number of departures) \u00f7 2] \u00f7 average headcount \u00d7 100<\/strong><\/p>\n

Average headcount is calculated as: (headcount on January 1 + headcount on December 31) \u00f7 2. Use this formula if you want to compare your rate with national or industry averages.<\/p>\n

The operational method is more down to earth. It focuses solely on departures and speaks more directly to managers looking to drive retention day to day:<\/p>\n

Turnover rate = (number of departures \u00f7 average headcount) \u00d7 100<\/strong><\/p>\n

Be careful: a fast-growing company that is hiring heavily will show a high INSEE turnover rate without actually losing employees. In this case, the operational method gives a more accurate picture.<\/p>\n

Step-by-step turnover rate calculation example<\/span><\/h3>\n

Take a company with 100 employees on January 1 and 110 employees on December 31. Over the year, it made 22 hires and recorded 12 departures.<\/p>\n

    \n
  • Average headcount: (100 + 110) \u00f7 2 = 105 employees<\/li>\n
  • INSEE method: [(22 + 12) \u00f7 2] \u00f7 105 \u00d7 100 = 16.2%<\/li>\n
  • Operational method: (12 \u00f7 105) \u00d7 100 = 11.4%<\/li>\n<\/ul>\n

    Two different results for the same reality. Always state which method you used when sharing a turnover rate. Otherwise, no meaningful comparison is possible.<\/p>\n

    What is the average turnover rate in France?<\/span><\/h2>\n

    According to INSEE, the average turnover rate in France is around 15% per year. This figure hides wide variations depending on industry and company size.<\/p>\n
