This single rule determines whether you pay €380/month or €680/month for health insurance in retirement. And most people only find out about it when it is too late to change anything.
The calculation
- Determine your total working life: first employment to pension start.
- Find the midpoint: divide working life by 2.
- Count how many years of the SECOND half you spent in GKV (public health insurance).
- If GKV years ≥ 90% of the second half: you qualify for KVdR.
Worked example: Sabine
- First job: age 22. Retirement: age 67. Working life: 45 years.
- Second half starts at: age 22 + (45/2) = age 44.5
- Second half duration: 22.5 years
- 90% threshold: 20.25 years of GKV needed in second half
- Sabine was in PKV from age 35 to 48 (13 years) then returned to GKV
- GKV in second half (age 44.5 to 67): 67 - 48 = 19 years... she FAILS by 1.25 years!
The children's credit that saves careers
Each child born or adopted adds 3 years of credited GKV time toward the 9/10 requirement. With 2 children, Sabine would gain 6 years of credit, bringing her to 25 years: comfortably above the 20.25 threshold.
Why freelancers and startup founders get trapped
A 10-year self-employment phase in PKV during your 40s can permanently disqualify you from KVdR. The fix: if you return to employment and GKV before age 55, you can rebuild the 9/10 ratio. After 55, the door closes permanently.
