KVdR 9/10 Rule Eligibility Calculator | Germany 2026

Why this one rule decides your health costs for 30 years

KVdR status is not a separate insurance, it is the CHEAP way of being publicly insured as a pensioner: contributions are charged only on your statutory pension and company pension (Betriebsrente), and the Deutsche Rentenversicherung pays half the rate on the statutory part. Private pensions like Riester and Rürup, rental income, dividends, none of it counts toward the premium.

Miss the 9/10 rule and the fallback, voluntary GKV membership, charges roughly 17.5% on essentially ALL retirement income up to the assessment ceiling: rents, private pensions, capital income included. For a retiree with €1,000 a month of rental income on top of a pension, the difference between KVdR and voluntary membership runs to thousands of euros a year, every year, for the rest of their life. One eligibility test, priced across three decades.

Only the second half of your career counts

The test ignores your first working decades entirely: take the span from your first job to your pension application, cut it in half, and demand GKV membership (compulsory, voluntary, or family-insured) for at least 90% of the SECOND half. A freelancer who was privately insured through their thirties and forties can still fail despite twenty earlier GKV years, and a late-career PKV switch is precisely the move that wrecks the ratio.

That geometry creates the planning insight most freelancers meet too late: every additional PKV year late in your career costs double, it adds to the second-half denominator while subtracting from the GKV numerator. Anyone within 15 years of retirement weighing a PKV switch should run this calculator FIRST, because German law also blocks the return road, switching from PKV back to GKV after age 55 is essentially impossible.

The child credits rescue more cases than any other rule

Since August 2017, each child adds a flat 3 years of deemed GKV membership to BOTH parents' second-half tally, biological, adopted, step, or foster, and regardless of whether the child was privately insured. Two children turn a 14-year record into a 20-year one, which converts a clean fail into a comfortable pass in the example above.

The credits exist because the old test structurally punished parents (career gaps, family insurance switches), and they are claimed, not automatic: the Krankenkasse checks eligibility when the pension application lands, and you provide the children's details with it. Freelancers with mixed PKV/GKV histories and children should never assume failure before counting the credits, three years per child moves the answer more than almost any late-career insurance decision.

If you still fail after credits, the calculator's 'years short' output is your planning number: it tells you exactly how many more GKV years to accumulate before applying for the pension, and for borderline cases, delaying the pension application by a year or two of GKV membership can flip the status for the following thirty.
