Psychosocial risks cost companies more than most decision makers have on their radar. This guide provides the figures, the legal framework, the calculation logic for your specific case - and an action plan for decision makers who do not want to wait until the advantage of others is no longer catchable.
You've launched a wellness app. Maybe even an EAP program, a yoga class, a mental health day on the calendar. Perhaps you even financed an external psychological counseling hotline and felt good about it - because you did something.
And yet absenteeism is increasing. Leaders burn out. Productivity is falling quietly and systematically, quarter by quarter.
It's not because your employees are ungrateful. It's not because you've invested too little. It's because you're solving the wrong problem.
You have offered wellbeing — and left psychosocial risks unmanaged. They're two completely different things. And confusing the two costs companies more every year than most decision makers are prepared to admit.
In our model calculations, the total costs of uncontrolled psychosocial risks amount to around 9,000€ per employee and year. This figure is not a lump sum from a single study — it is the result of a full cost analysis based on BAuA, IGA and own business case data, which brings together several cost drivers that simply do not appear in classic absenteeism reports.
The first and most visible post is absenteeism. Based on the 2024 BAuA cost calculation, around 1,500 to 2,000€ per employee and year can be derived conservatively as direct default costs - continued payment of wages, administrative costs, loss of productivity in the transition phase. That is the number that appears in HR reports. The number that is being discussed. And at the same time, the smallest part of the problem.
The second item is the more expensive — and the more invisible. Presentalism: Employees who come to work but work well below their capacity. Exhausted, stressed, internally disconnected. Research consistently shows that presentism costs two to three times absenteeism — 65% of all health-related productivity losses are caused not by sick reports, but by employees who nevertheless show up. (IGA facts 6/BAuA, 2024) In our model calculation, this corresponds to around 4,000€ per employee and year. The employee who comes anyway costs your company more than the employee who stays at home and recovers. It's counterintuitive. That is why it is systematically underestimated. And that is why it does not appear in any classic absenteeism analysis - even though it is by far the biggest cost driver.
The third item is turnover and recruitment. Up to 40% of voluntary dismissals are psychologically related. Depending on the position and industry, replacement costs range from 50 to 200% of the annual salary - in our conservative model calculation, around 2,400€ per employee and year, calculated on a pro rata basis. This is the number that managers most often underestimate because it does not appear directly in a line of the budget, but is spread across recruiting fees, training time, outflow of knowledge and temporary loss of productivity.
In addition, in our full cost analysis, there are two other items that do not appear in any standard invoice. Loss of innovation due to limited problem-solving ability and declining creativity among chronically exhausted teams — around 700€ per capita and year in our model calculation. (Based on WHO data on mental health and cognitive performance) As well as compliance and insurance risks due to lack of risk assessments, growing ESG reporting requirements and increasing regulatory requirements — around 500€ per capita and year.
In our model calculation, this adds up to around 9,000€ per employee and year. That is the number that belongs in your next executive meeting — not as a threat, but as a basis for a rational investment decision.
Independent data confirm the picture — and makes it worse. 17.4% of all working days due to illness in Germany are due to mental illness — almost every fifth day of absence. (DAK-PsychReport 2025) Since 2014, these absences have increased by 47%, faster and more consistently than any other disease group. (AOK Absence Report 2024/2025) Depression causes 182.6 days of incapacity for work per 100 insured persons - it is now the top diagnosis among all mental illnesses. (DAK Psychreport 2025)
When an employee is absent due to a mental illness, they are gone for an average of 33 to 40 days — almost twice as long as if they were physically ill. (DAK/AOK, 2024) This is not just a medical fact. It is a business one. After all, 33 to 40 days of downtime in full cost accounting means damage that quickly reaches five-digit ranges for a single manager - even before fluctuation costs are included.
These figures do not describe an exceptional situation. They describe the normal situation in German companies of all sizes and sectors. The question is no longer whether psychosocial risks affect your company. The only question is whether you control them — or whether they control you.
The issue is not just an economic one. It is also a legal one. And this has been the case for almost three decades — a fact that receives surprisingly little attention in many companies.
Section 5 ArbSchG obliges employers in Germany to assess working conditions - explicitly including psychological stress. Section 6 ArbSchG requires documentation of this assessment. Section 3 ArbSchG goes even further: It requires not only recording and documentation, but effective measures - concrete, traceable, with proven effect. The Occupational Health and Safety Act does not include a “nice-to-have” category for mental health. It only knows duty. And this obligation has been in force since the amendment to the Occupational Health and Safety Act 2013.
The BAuA research project f2358 has examined over 6,500 companies. Result: Only a minority actually carries out the risk assessment of psychological stress in a legally secure manner. (BAUA, research project f2358) Current GDA monitoring data estimate the implementation rate across industries at 35 to 50% - and this includes companies that have formally carried out a GBU but barely implemented the content. The core findings from the qualitative BAuA interviews go to the heart of the problem: Companies do not fail because of will. They fail because of the tools. Psychosocial risks are regarded as “complex assessment problems” — too abstract, too difficult to measure, too far removed from traditional occupational health and safety thinking.
The regulatory landscape is changing at a rate that many decision makers underestimate. ISO 45003:2021 - the first international standard exclusively for psychosocial risk management in the workplace - defines five core requirements. First, the systematic identification of psychosocial risks: active recognition of working conditions, circumstances and requirements that can affect mental health — not reactively after the initial burnout, but preventively as an ongoing task. Second, structured risk assessment based on defined primary factors: work organization, social environment, work environment, management behavior. This differentiation is crucial because anyone who does not know which factor is causing the problem cannot derive an effective measure. Thirdly, the implementation of specific control measures — not proposed measures, not recommendations for action, but binding measures with a defined effect and follow-up. Fourthly, raising awareness and developing competencies at all levels — from management to managers to occupational safety specialists. Psychosocial risks are not an HR issue. They are a management task. Fifthly, structured return management for affected employees — a system that ensures that the causes of a burden have been known, addressed and traceably eliminated. Otherwise, the next sick report is only a matter of time.
From 2025, the CSRD will require companies with more than 500 employees to report in detail on social, occupational and health aspects in ESG reporting — psychosocial risks are explicitly part of these requirements. (EU Directive CSRD, 2023) D&O insurers are increasingly evaluating active management of mental health risks as a risk indicator when designing policies. ESG funds and institutional investors are considering mental health measures as tough decision-making criteria. Anyone who does not collect data today cannot report 2025. And anyone who is unable to report in 2025 has a problem that goes far beyond HR — one that ends up on the board of directors.
I'll be fair: This isn't an attack on wellness offerings. Psychological support services are valuable. Prevention measures have their place. But they don't solve the real problem — because they weren't structurally built for it.
A wellness app is an offer. It is waiting to be used. A psychosocial risk infrastructure is a system — it measures, prioritizes and acts regardless of whether the individual employee is just motivated enough to open an app. That is the fundamental difference. And it starts with the question of how to measure.
Classic BGM tools measure once. Usually once a year. With an anonymous survey that ends up in a mailbox six weeks later as a PDF report - and rarely results in concrete measures. It's not a controller. This is a snapshot that creates the appearance of control. And the GBU psyche without systematic derivation of measures is the same in legal disguise.
Effective psychosocial risk management requires three levels at the same time. The first is the legally secure GBU Psyche with scientifically validated instruments - MOLA, KFZA or COPSOQ, depending on company size, industry and issue. These tools are established in occupational psychology research and are geared to the specific requirements of the GBU psyche in accordance with §§ 5, 6 ArbSchG. The GBU Psyche is the only mandatory occupational psychology analysis and at the same time the baseline measurement on which any further intervention must be based. Anyone who introduces a BGM without GBU takes vitamins without having done a blood count first.
The second level is pulse checks with static and rolling items using validated methods - not as a mood barometer, but as an early warning system between GBU cycles. Where does stress grow? Where does a team tip over? Where is a manager on a path that no one is slowing down? This continuous measurement is what makes an annual compulsory exercise a real management tool.
The third level is immediate response: immediate aid for affected employees and direct immediate measures in accordance with § 3 ArbSchG - documented, legally secure, traceable. Not in four weeks after the next steering committee. But when the system identifies a need for action.
That is the difference between a health report and a control infrastructure. Between “we know there is a problem” and “we know where, how serious — and we've already taken action.”
The data is clear. 9,000€ total damage per employee and year in our full cost analysis. ROI of 2.70 to 4. 8:1 on average, with higher scores with early intervention. Legally mandatory since 1996. Relevant in ESG reporting from 2025. Increasingly rated by insurers, investors and talent — and increasingly understood as a competitive factor by companies that closely monitor their market.
Anyone who really wants to manage psychosocial risks — economically effective, legally secure, verifiable — doesn't need another app. They need infrastructure. And anyone who builds up this infrastructure today while others are still discussing wellness budgets is building an advantage that reinforces itself over time. In this guide, we go deeper: What the calculation logic for your company actually looks like, what ISO 45003 really requires - and which five steps decision makers should take now.
Most BGM discussions don't fail due to a lack of will. They fail because of the missing number. Nobody sits in a strategy meeting and consciously decides against psychosocial risk management. The decision against this is usually silent - because the damage remains invisible and the investment is visible. This changes as soon as you apply the full cost analysis to your own company.
The calculation logic follows a clear model, which we developed based on BAuA, IGA and our own business case data. The starting point is the BAuA cost calculation for incapacity for work: A working day lost costs an employer around 123€ in direct wage and productivity costs on average. (BAuA, 2024) With an average of 15 psychologically related absences per affected employee, this results in absenteeism costs of around €1,850 per person in the risk group — that is the visible part. The invisible part, presentism, multiplies this value by a factor of 2 to 3 based on IGA research and results in a total loss of productivity of around 5,500 to 6,000€ per affected employee. (IGA facts 6, BAuA, 2024) In our full cost analysis, fluctuation costs, loss of innovation and compliance risks add up to around 9,000€ per employee and year — calculated across the entire workforce, not just those who are visibly affected.
Why across the entire workforce? Because psychosocial risks are not an individual issue. They are a systemic phenomenon - and their costs are spread across all levels of an organization, even where no one has reported ill and no one has resigned internally. The employee who works but has been under chronic stress for months produces measurably worse results, makes poorer decisions and transfers his exhaustion to his team. It's not a psychological phenomenon. It's a business one.
What does this mean for different company sizes — specifically and in a calculated way?
For a company with 50 employees, our model calculation shows an annual risk potential of around 450,000€. A realistic investment in structured psychosocial risk management is 15,000 to 25,000€ per year — this corresponds to a unique GBU Psyche, a pulse check system and basic emergency aid infrastructure. With a cost reduction of just 5% — which corresponds to savings of around 22,500€ — the investment is covered in the first year. That is not an optimistic scenario. That is the conservative entry level.
For a company with 250 employees, the picture is changing significantly. Risk potential: around €2.25 million per year. Realistic investment: 60,000 to 80,000€ per year for a complete three-stage system. A 5% absenteeism reduction results in savings of around 112,500€ — that is an ROI of more than 1:1 in the first year, without taking into account fluctuation and innovation effects. Whoever takes this figure into their next budget discussion will have a different discussion than before.
For a company with 1,000 employees, the annual risk potential in our model calculation is around 9 million €. Even an ambitious investment of 200,000 to 300,000€ per year — for a fully developed system with continuous monitoring, validated pulse checks and structured leadership development — represents less than 3.5% of the risk potential. An improvement of 10% across all cost drivers results in annual savings of €900,000. This is one of the most profitable allocation decisions in the entire HR budget — and at the same time one that is not even on the agenda in most companies.
The decisive variable in this calculation is not the investment amount. It is the time of intervention. Anyone who only acts when managers fail or fluctuation becomes apparent pays for the most expensive form of prevention: retrospective. An intervention that stabilizes an employee before burnout costs a fraction of the intervention that starts after a six-week sick report. This is not only clinically evident — it is imperative from a business perspective.
ISO 45003:2021 is frequently mentioned in HR discussions — but rarely really understood. It is not just another compliance standard that is checked off once a year. It is the first international standard dedicated exclusively to managing psychosocial risks in the workplace. And it defines, with precision that is rarely achieved in German occupational safety practice, what effective psychosocial risk management must achieve structurally.
The first core requirement is the systematic identification of psychosocial risks. ISO 45003 explicitly distinguishes between different categories of sources of risk: factors of work organization such as workload, autonomy, role clarity and time requirements; factors of the social work environment such as leadership behavior, team dynamics and interpersonal conflicts; factors of the work environment such as physical conditions and ergonomic design; as well as factors related to the work activity itself, such as emotional demands, cognitive load and the meaningfulness of the task. This differentiation is not academic. It is operationally decisive: Anyone who does not know whether the burden is caused by work organization, leadership behavior or social dynamics cannot derive effective measures.
The second core requirement is structured risk assessment based on defined primary factors. ISO 45003 requires not only the recording of symptoms — i.e. absenteeism, fluctuation rates, survey results — but also the systematic evaluation of the underlying risk factors. Who is assessed, who evaluates, with which methods and according to which criteria, must be documented and comprehensible. An anonymous employee survey, which is evaluated by an external consultancy and whose results end in a presentation six weeks later, generally does not meet this requirement. A validated GBU psyche with MOLA, KFZA or COPSOQ, whose results are transferred directly into a documented action plan, does it.
The third core requirement is the implementation of specific control measures. ISO 45003 explicitly distinguishes between primary, secondary and tertiary interventions. Primary interventions aim at eliminating or reducing the source of risk itself — i.e. working conditions that generate psychosocial risks. This is the most effective and at the same time the rarest form of intervention. Secondary interventions strengthen individual resilience — that is, what most wellness programs do. Tertiary interventions support employees who have already been affected during recovery and return. ISO 45003 clarifies: Anyone who focuses exclusively on secondary and tertiary interventions engages in symptom treatment — not risk management.
The fourth core requirement is to raise awareness and develop competencies at all levels of the company. The standard requires that all relevant actors — management, managers, HR, occupational safety specialists, works council — are not only sensitized but empowered: able to identify, identify, escalate and address psychosocial risks. This requires structured training programs, not one-off awareness campaigns. And it requires a corporate culture in which psychological stress can be addressed without stigma.
The fifth core requirement is structured return management for affected employees. ISO 45003 requires a system that ensures that an employee who returns after a psychologically related break does not return to the same conditions that caused their failure. In practice, this system is completely absent in most companies. The result: reintegration rates far below possible — and subsequent losses that are not recorded as avoidable in any absenteeism statistics.
Why is ISO 45003 becoming a market requirement? Because three developments overlap. The CSRD reporting requirement from 2025 in fact forces companies to prove that psychosocial risks are systematically recorded and addressed — ISO 45003 is the only internationally recognized framework that fully covers this requirement. The increasing evaluation of ESG criteria by institutional investors and insurers makes dealing with psychosocial risks an explicit assessment criterion. And the shortage of skilled workers makes ISO 45003-compliant companies an objectively measurable differentiator in the competition for talent — in a working world in which employees are increasingly not just asking “What do you pay?” but “How are you dealing with my mental health?”
I am not concluding this guide with an abstract vision, but with what I specifically recommend to every CHRO, every management and every HR manager - regardless of whether you work with mentalport or not.
The first step is an honest inventory in three questions. Are you carrying out a GBU Psyche - and if so, is it carried out on the basis of validated instruments, documented and linked to a specific action plan? Between GBU cycles, do you have a system that records changes in the psychological stress situation of your workforce - or are you blind until the next measurement? And if there is a need for action in one of your teams today: How long does it take for someone to act - and is this reaction documented? The answers to these three questions will show you whether you have a BGM offering or a control infrastructure.
The second step is to quantify your own risk potential. Take your number of employees and multiply it by 9,000€ - that is the starting value of your full cost analysis based on our model calculation. Then compare this figure with your current BGM investment. The difference is the basis for your next budget meeting — not as a threat, but as a rational basis for an investment decision that pays off in every scenario.
The third step is the structural decision: treat psychosocial risks as a care issue — or as a management task. Anyone who opts for control needs a system with three clearly defined levels: legally compliant measurement as a basis, continuous monitoring as an early warning system, immediate ability to act as a response level. Anyone who opts for care continues to buy wellness apps - and continues to pay 9,000€ per capita and year.
The fourth step applies specifically to companies with 500 employees or more: Start building CSRD-compatible documentation now. Anyone who starts collecting data in 2025 that must already be reported in 2025 has missed the window. Establishing a documentable database requires at least two to three measurement times in order to be able to demonstrate reliable trends. Anyone who starts today has a data basis in 2026. Anyone who waits has a compliance problem that ends up on the board of directors.
The fifth step is leadership development as a structural investment — not as one-off training. Managers who do not know, recognize and cannot address psychosocial risks are a structural risk in a regulatory and economic environment that is fundamentally changing. Not because they're bad leaders — but because they're working without the right tools.
The sixth step is the one that very few people have on their radar: positioning to the outside world. Companies that are demonstrably compliant with ISO 45003 already have a differentiating factor in the competition for talent, in ESG assessments and against institutional investors. This advantage is growing — because regulatory and social requirements are growing. Whoever builds it today has it. If you wait, you have to catch up on it at some point under time pressure - at the highest price.
The companies that understand this today are just building a head start — in resilience, in compliance, in leadership, in the ability to manage human capital for what it is. Not everyone will be able to catch up on this advantage. The gap between companies that see psychosocial risks as a management task and those that treat them as a care issue will become visible in the next two to three years — in absenteeism statistics, in turnover rates, in ESG ratings, in the ability to attract and retain talent.
Now calculate what uncontrolled psychosocial risks actually cost your company - and what a structured intervention would be worth in return.

In our full cost analysis based on BAuA, IGA and our own business case data, the total costs amount to around 9,000 euros per employee and year. This figure consists of five cost drivers: absenteeism (approx. 1,500 to 2,000 euros), presentism (approx. 4,000 euros), fluctuation and recruitment (approx. 2,400 euros), loss of innovation (approx. 700 euros) and compliance and insurance risks (approx. 500 euros). The first two items are based on validated BAuA and IgA data, the others on our own model calculation.
Absenteeism refers to absenteeism due to illness that appears directly in absenteeism statistics. Presentalism describes the opposite: Employees show up for work even though they are psychologically stressed or ill, and work well below their capacity. According to IGA facts 6 and BAuA, 65 percent of all health-related productivity losses are caused by presentism, not absenteeism. The costs are two to three times higher than in the case of a direct failure because they remain invisible and are never controlled.
The risk assessment of psychological stress is a legal obligation in accordance with paragraphs 5 and 6 ArbSchG for all employers in Germany, regardless of company size and industry. It requires the systematic recording, documentation and elimination of psychological stress at work and has been in force since 1996. Paragraph 3 ArbSchG requires additional effective measures, not just documentation. According to BAuA research project f2358, however, only a minority of German companies actually carry out the GBU Psyche in a legally secure manner.
ISO 45003:2021 is the first international standard exclusively for psychosocial risk management in the workplace. It requires, firstly, the systematic identification of psychosocial risks according to defined categories, secondly, a structured risk assessment based on primary factors such as work organization, leadership behavior and social environment, thirdly, the implementation of concrete control measures with priority on primary interventions, fourthly awareness-raising and competence development at all levels of the company, and fifthly, structured return management for affected employees. The standard makes it clear that pure wellness offers are no substitute for risk management.
The IGA Report 16 shows an average of 2.70 euros in savings per 1 euro invested, with a range of 1:2 to 1:6 depending on the intervention. EU-OSHA documents 2.5 to 4.8 euros in ROI per euro invested. Deloitte UK averages around 5:1 for structured early interventions. The decisive variable is not the investment amount, but the time: The earlier you intervene in the load process, the higher the ROI.
The Corporate Sustainability Reporting Directive requires companies with 500 or more employees to report in detail on social, occupational and health aspects in ESG reporting from 2025. Psychosocial risks are an explicit part of these requirements. Companies must provide concrete data, not declarations of intent. Anyone who does not build up a database today will not be able to report 2025. Establishing a reliable data base requires at least two to three measurement times.
A wellness app is a voluntary benefit offer, which is waiting to be used. It does not measure psychosocial risks, does not produce GBU-compliant documentation and does not derive any measures in accordance with paragraph 3 ArbSchG. A psychosocial risk infrastructure such as mentalport combines three levels: legally secure GBU psyche with validated instruments such as MOLA, KFZA or COPSOQ as a legal basis, continuous pulse checks as an early warning system between GBU cycles, and immediate immediate assistance as well as documented immediate measures when action is identified.
The starting value is simple: The number of employees multiplied by 9,000 euros results in the annual risk potential in our full cost analysis. For 50 employees, this is around 450,000 euros, for 250 employees around 2.25 million euros, for 1,000 employees around 9 million euros. You compare this figure with your current BGM investment.
