iga.Report: WHP ROI

Does WHP really pay off? What iga.Report 40 shows about the ROI of workplace health promotion

iga.Report 40 evaluates 47 ROI figures from international WHP studies: average ROI 1:2.7 — with structured implementation, every euro invested returns €2.70 on average. 85% of the ROI figures are above 1. Implementation quality is decisive; the proof for your own company comes from your own measurement.

iga.Report 40: WHP ROI and effectiveness

Metric	Value per iga.Report 40	Note
Average ROI of WHP measures	1:2.7 (mean of 47 ROI figures)	Mean of all 47 ROI figures; the range from −3.3 to 15.6 shows how widely individual values vary
Programs with positive ROI	85% of the 47 ROI figures are above 1	Confirmed: the majority of programs pay off
ROI range	−3.3 to +15.6	Outliers in both directions — implementation is decisive
Study base	140 studies, approx. 500,000 participants	Overview of international reviews — not limited to Germany
EU studies specifically	Average ROI of 1:1.7 (five studies)	Lower than the overall value — mind the EU context
One-off health actions without structure	No separate ROI evidence	The report sees WHP as a continuous process, not a one-off intervention

How does the iga.Report arrive at an ROI of 1:2.7 — and what does that mean for your report to management?

iga.Report 40 does not calculate an ROI of its own; it evaluates 47 ROI figures from existing studies — together they yield an average ROI of 1:2.7. Overall, the report synthesizes 140 international studies with approximately 500,000 participants, making it methodologically far more robust than individual company case studies. It is published by the Initiative Gesundheit und Arbeit (iga), a joint initiative of Germany's statutory health and accident insurers.

What goes into the ROI figures: in the evaluated studies, mostly direct healthcare costs (e.g., medical services) and indirect costs, above all from sickness absence. An ROI above 1 means the benefit exceeds the expenditure. Because German employers usually do not bear direct healthcare costs themselves and most studies come from the US, the figures are only partly transferable. Presenteeism — working while sick — is hardly captured by the studies; the report recommends giving productivity more weight in future.

For your report to management: take your absence costs (sick days x daily rate) as the baseline and set your WHP investment next to it. Whether the program pays off is shown by your own measurement in the following year — the study value of 1:2.7 provides context; it is not a promise.

Note: These figures and calculations are based on the German statutory health insurance (GKV) system and German legal framework; they may not translate directly to other jurisdictions.

Which WHP measures work according to the iga — and which do not?

iga.Report 40 draws a clear line between evidence-based and non-evidence-based measures. Evidence-based: stress management (cognitive behavioral techniques), leadership training, movement-friendly workplace design, and addiction prevention with early detection.

Low or no evidence: standalone health days without follow-up, fruit-basket programs, one-off webinars with no structural connection. The report stresses that workplace health promotion should be continuous rather than consist of one-off interventions. Implementation quality also explains the wide range (−3.3 to +15.6) in the ROI figures.

Practical consequence: a poorly implemented program can land well below this average. The specific measure is secondary — needs analysis, embedding in an overall system, and impact monitoring are what matter.

Stress management: at least 6 sessions, needs-based, with impact monitoring
Healthy leadership: not a one-off — recurring training cycles
Movement: infrastructure (bike racks, standing desks) often works better than courses alone
Addiction prevention: early detection by managers is a strong lever
No effect: isolated standalone measures without WHP integration

How do you calculate the WHP ROI for your company — step by step?

Step 1 — Gather baseline data: average sick days per employee (e.g., 18 days/year), number of employees (100), cost per sick day (guide: around €300, Personalwirtschaft 2024, German figures). Baseline cost block: 18 × 100 × €300 = €540,000/year.

Step 2 — Put the study value in context: at an ROI of 1:2.7 (per iga.Report, on average, with structured implementation), an assumed WHP investment of €15,000–25,000/year for 100 employees would mathematically return €40,500–67,500/year — a study value, not a promise. Whether your program achieves this is shown by your own measurement.

Step 3 — Keep presenteeism in mind: according to BAuA GD 60, presenteeism costs exceed direct absenteeism costs at the macroeconomic level. Presenteeism hardly enters the ROI figures of the iga.Report — so the study value tends to understate the potential. Your own extrapolation does not replace measurement.

Step 4 — Mind the EU context: the five EU studies show an average ROI of 1:1.7 — lower than the overall value. 1:2.7 (per iga.Report, on average, with structured implementation) remains the benchmark; what your program delivers depends on implementation quality and the baseline sick-leave rate — and is shown by your own measurement.

Note: this German legal and statutory-insurance context (GKV) does not automatically apply outside Germany — consult local regulations for your jurisdiction.

Key takeaways

Note: figures reflect the German statutory health insurance (GKV) context. iga.Report 40: average ROI for WHP = 1:2.7 with structured implementation — from 47 ROI figures; study base around 140 studies with 500,000 participants.
85% of the 47 ROI figures are above 1 — most of the programs studied paid off.
ROI range of −3.3 to +15.6 — implementation quality is the decisive moderator.
Presenteeism costs exceed absenteeism costs (BAuA GD 60) — WHP has to tackle both.
The EU studies are lower on average (1:1.7) — the benchmark remains 1:2.7 per iga.Report, on average, with structured implementation.

Frequently asked questions

How reliable are the iga ROI figures?+

iga.Report 40 summarizes reviews covering around 140 studies with approximately 500,000 participants — methodologically more solid than individual studies. The 1:2.7 comes from 47 ROI figures. However, the range of −3.3 to +15.6 shows that poorly implemented programs can have a negative ROI. The average is a benchmark for programs implemented in a structured way, not a promise for one-off actions.

Does the iga ROI also apply to small businesses?+

The report does not break down the ROI figures by company size, but by sector, country, study quality, and number of participants, among other things. At small companies your own figures fluctuate more: a single long-term sick-leave case (e.g., a mental health condition lasting 90 days) can significantly skew the statistics at a company with 20 employees. Small businesses benefit especially from measures with low entry effort — a digital WHP platform is a good way to start; if a consultant joins, they work on the same platform.

How long does it take for WHP measures to show an ROI?+

In the studies evaluated by iga.Report 40, the economic indicators were collected between eight months and eight years after the measures began. Because workplace health promotion is designed to be continuous, its effects are also expected on an ongoing basis. For your report to management, short-term indicators matter — sick-leave trends and survey results can be reported within a year.

What is the difference between absenteeism and presenteeism costs?+

Absenteeism = employees are sick and absent. Costs: continued wage payment plus coverage. Measurable via sick days. Presenteeism = employees are present but sick or exhausted — and only partly able to perform. Costs: harder to measure, but according to BAuA GD 60 they exceed direct absenteeism costs at the macroeconomic level. WHP reduces both — measures against presenteeism (stress management, leadership culture) often have a stronger long-term effect.
