GKV vs PKV Lifetime Cost Calculator

Health insurance premiums reduce your taxable income (Sonderausgaben). GKV contributions are 100% tax-deductible, while only ~80% of PKV premiums count as Basisabsicherung and are deductible. At a 42% marginal rate, this 20% gap means €100 of PKV premium costs ~€66 after tax, while €100 of GKV costs only ~€58. The higher your tax bracket, the more this difference matters.

German tax law (§10 EStG) only allows deducting the portion of your PKV premium that covers basic healthcare — roughly 80% of the health premium. The remaining 20% (covering extras like single rooms, chief physician treatment) is not tax-deductible. Your full Pflege (long-term care) premium is always 100% deductible.

In retirement, your employer subsidy disappears and is replaced by a pension fund subsidy (Zuschuss der Rentenversicherung) of 8.75% of your gross pension — typically much less than the employer subsidy. Meanwhile, PKV premiums have compounded for decades. The 10% gesetzlicher Zuschlag drops off at age 60, but cumulative increases usually far outweigh this reduction.

When you retire, the Deutsche Rentenversicherung pays 8.75% of your gross pension as a health insurance subsidy, capped at half your total PKV premium. For a €2,200 pension, that is ~€193/month — much less than a typical employer subsidy of €400+. This gap is why PKV costs jump significantly at retirement.

Tax class determines your income tax calculation. Class III (married, higher earner) uses Splittingverfahren — your income is halved, taxed, then doubled. This usually results in a lower marginal rate, which reduces the tax benefit of health insurance deductions. Classes I and IV use standard individual taxation.

Switching from PKV back to GKV becomes very difficult after age 55. Before that, you need your income to drop below the Versicherungspflichtgrenze (€73,800 in 2025) for at least one year. Common strategies include reducing hours, taking a sabbatical, or changing to a lower-paying role. This calculator helps you understand the financial impact of staying in PKV vs what GKV would cost.

The projection models salary growth, PKV premium increases, BBG adjustments (+3%/yr), pension growth (+1.5%/yr), and cold progression (+2%/yr tax threshold scaling). PKV premiums compound each year, but tax deductions grow too. The crossover point — when GKV becomes cheaper after tax — depends on how fast PKV premiums outpace the growing deduction benefit and the retirement transition.
