Cost of employee turnover in Germany

Five cost blocks per departure

International research (SHRM, Gallup, Deloitte) groups turnover cost into five blocks: recruiting (ads, headhunters, selection), onboarding (formal training, mentoring), productivity gap (3–6 months reduced output), knowledge loss (informal networks, domain knowledge) and transition cost (overburdened colleagues, temporary cover).

Link to mental load

Burden patterns from the GB Psych — high emotional demands, low control, weak leadership — correlate in longitudinal research (Gallup, Stepstone) with intent to leave. A consistently executed GB Psych with action follow-through typically lowers turnover by 10–25 %. For a 100-person company at 15 % turnover that is 1.5–4 fewer departures per year — i.e. €75,000–€200,000 annually.
