Employee turnover costs more than just filling a vacancy. The real costs lie in recruitment, onboarding time, lost productivity, loss of knowledge, and the added pressure on the team left behind. If you want to build a strong business case internally for investing in employee retention, you start by making these cost items transparent for your own organization, rather than relying on general rules of thumb.<\/span>\u00a0<\/span><\/p>\n

Why the costs of turnover are often underestimated<\/span><\/h2>\n

When an employee leaves, people often look only at the direct recruitment costs: a job posting and an ad. That is only part of the story. The largest cost items are often invisible:<\/span>\u00a0<\/span><\/p>\n

    \n
  1. The time a manager spends conducting job interviews<\/span>\u00a0<\/span><\/li>\n
  2. The period during which a position remains vacant and work is left undone or is taken over by colleagues<\/span>\u00a0<\/span><\/li>\n
  3. The reduced productivity of a new employee in the first months<\/span>\u00a0<\/span><\/li>\n
  4. Knowledge and client relationships that leave with the employee<\/span>\u00a0<\/span><\/li>\n
  5. The extra workload on the team, which in turn can contribute to absenteeism or another departure<\/span>\u00a0<\/span><\/li>\n<\/ol>\n

    Without taking these items into account, employee retention seems like a \u201cnice to have.\u201d Therefore, a well-substantiated business case is needed to be taken seriously internally.<\/span>\u00a0<\/span><\/p>\n

    What are the cost components of employee turnover<\/span>\u00a0<\/span><\/h2>\n

    To properly calculate the costs of turnover, you divide the costs into four categories:<\/span>\u00a0<\/span><\/p>\n

      \n
    1. Recruitment costs <\/span><\/b>Consider job postings, agency fees, and the time that HR and managers spend on interviews and evaluations.<\/span><\/li>\n<\/ol>\n

      In addition: It is not only about the lower output of the new employee, but also about the time that colleagues and managers spend on guidance and knowledge transfer.<\/span>\u00a0<\/span><\/p>\n

        \n
      1. Onboarding and training costs<\/span><\/b>Time spent by coworkers and the manager on onboarding, materials, training costs, and arranging access.<\/span>\u00a0<\/span><\/li>\n
      2. Loss of productivity<\/span><\/b>The period during which a position is vacant, plus the time it takes for a new employee to become fully productive. This is often the largest and least visible cost item.<\/span>\u00a0<\/span><\/li>\n
      3. Indirect costs<\/span><\/b>The potential loss of client relationships or project expertise, as well as the risk that increased workloads may contribute to absenteeism or further departures. This directly relates to how structural recognition can influence absenteeism within an organization.<\/span>\u00a0<\/span><\/li>\n<\/ol>\n

        Calculation Model: How to Calculate Turnover Costs Step by Step<\/span>\u00a0<\/span><\/h2>\n

        Use this as a starting point and supplement it with your own organization's figures.<\/span>\u00a0<\/span><\/p>\n

        Step 1: Determine the job posting period<\/span><\/b>\u00a0On average, how many weeks does a position remain open? From the time the previous employee leaves until the successor's first day on the job.<\/span>\u00a0<\/span><\/p>\n

        Step 2: Calculate the recruitment costs<\/span><\/b>\u00a0Add the direct costs (advertisement, agency) to the time spent by HR and the manager, multiplied by their hourly rate.<\/span>\u00a0<\/span><\/p>\n

        Step 3: Calculate the training period and loss of productivity<\/span><\/b>\u00a0Estimate how many weeks or months it takes for a new employee to be fully productive and what percentage of the salary is \u201clost\u201d during that period due to reduced output.<\/span>\u00a0<\/span><\/p>\n

        Step 4: Include indirect costs in your calculations<\/span><\/b>\u00a0Consider factors such as colleagues working overtime, the possible use of temporary staff, and the risk of reduced customer satisfaction during the transition period.<\/span>\u00a0<\/span><\/p>\n

        Step 5: Add up everything per departing employee<\/span><\/b>\u00a0The sum of these four steps provides a realistic picture per departure. Multiply this by the number of employees leaving annually to see the total impact at the organizational level.<\/span>\u00a0<\/span><\/p>\n

        Important: For steps 3 and 4, do not treat external rules of thumb as established facts. Ask your finance department or managers for a realistic estimate based on your own roles and processes. A generic industry figure is less convincing to senior management than a calculation based on your own organization.<\/span>\u00a0<\/span><\/p>\n

        Example:<\/span><\/b>\u00a0<\/span><\/p>\n\n\n\n\n\n\n\n\n\n
        An employee with a gross annual salary of \u20ac45,000 is leaving.<\/span><\/b>\u00a0<\/span><\/td>\n<\/tr>\n
        Recruitment: \u20ac2,500<\/span><\/b>\u00a0<\/span><\/td>\n<\/tr>\n
        Time HR + manager: \u20ac1,500<\/span><\/b>\u00a0<\/span><\/td>\n<\/tr>\n
        Vacancy 8 weeks: \u20ac5,000 productivity loss<\/span><\/b>\u00a0<\/span><\/td>\n<\/tr>\n
        3-month training period: \u20ac4,500 in lost productivity<\/span><\/b>\u00a0<\/span><\/td>\n<\/tr>\n
        Extra workload colleagues: \u20ac1,500<\/span><\/b>\u00a0<\/span><\/td>\n<\/tr>\n
        Total estimated cost: \u20ac15,000<\/span><\/b>\u00a0<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

        With 20 employees leaving each year, the potential impact thus amounts to \u20ac300,000.<\/span><\/b>\u00a0<\/span><\/p>\n

        From Numbers to Action\u00a0<\/span>\u00a0<\/span><\/h2>\n

        Calculating turnover costs is the starting point. The next question is:\u00a0<\/span>what can you do to prevent departure<\/span><\/i>? This is where structural valuation comes into play. Research, the\u00a0<\/span>employee retention strategy: why employees stay<\/span><\/a>\u00a0show that employees leave more often due to a lack of recognition and connection than because of salary alone. That makes appreciation a direct lever in a business case: every employee you retain through structural recognition saves the full turnover costs you calculated in the financial model.<\/span>\u00a0<\/span><\/p>\n

        That same emotional connection to the organization is one of the strongest predictors of retention, as described in\u00a0<\/span>how emotional connection keeps your best people<\/span><\/a>. When you combine these two elements, you create a business case based on cost savings that also provides a concrete explanation for why people stay.<\/span>\u00a0<\/span><\/p>\n
