GKV vs PKV Lifetime Cost Calculator

Health insurance premiums reduce your taxable income as Sonderausgaben. GKV contributions are 100% deductible. For PKV, only the Basisabsicherung portion — roughly 80% of your health premium — is deductible under §10 EStG. The remaining ~20%, which funds extras above the statutory standard (private rooms, free choice of physician), is not tax-deductible. At a 42% marginal rate, €100 of deductible PKV costs about €58 after tax — but the non-deductible 20% costs the full €100. The higher your tax bracket, the more this gap matters.

German tax law (§10 EStG) only permits deducting the part of your PKV premium covering basic statutory-equivalent healthcare — typically around 80% of your health premium. The remaining ~20%, which funds extras above the GKV standard (single hospital rooms, free choice of chief physician), is not tax-deductible. Your Pflegeversicherung (long-term care insurance) premium is always 100% deductible regardless of insurer.

At retirement, your employer subsidy stops. It is replaced by a Zuschuss der Rentenversicherung — a pension fund health subsidy of 8.75% of your gross state pension, capped at 50% of your actual PKV premium. For a monthly pension of €2,200, that amounts to roughly €193/month — considerably less than a typical working-age employer subsidy of €400+. Meanwhile, PKV premiums have compounded for decades. This gap is why PKV costs often increase sharply in the first years of retirement.

Deutsche Rentenversicherung pays 8.75% of your gross state pension directly toward your PKV premium. This is capped at half your actual premium. The difference between this subsidy and your full premium is your out-of-pocket cost — and it can be substantially larger than the employer subsidy you received during working years. This transition explains why many PKV members see their net health insurance cost roughly double at retirement.

Tax class determines how your income tax is calculated. Class III (married, primary earner) uses Splittingverfahren — the joint income is halved, taxed, then doubled — typically producing a lower marginal rate than Class I (single). A lower marginal rate means the tax deduction for health insurance premiums is worth fewer euros, which shifts the after-tax comparison between GKV and PKV. The lifetime cost difference can vary significantly depending on your filing status.

Before age 55, switching back is theoretically possible if your income falls below the Versicherungspflichtgrenze (€73,800 in 2025) for at least 12 consecutive months — for example through reduced hours, a sabbatical, or a role change. After 55, re-entry is generally blocked even if income drops, unless you return to employment from self-employment. This calculator helps you model the long-term financial impact of staying in PKV compared to what GKV would have cost.

The model projects salary growth, annual PKV premium increases, BBG (Beitragsbemessungsgrenze) adjustments, pension growth, and gradual tax bracket movement. PKV premiums compound year over year, but so does the tax deduction. The crossover point — where GKV becomes cheaper after tax — depends primarily on how fast PKV premiums outpace salary growth and the sharp reduction in subsidy at retirement.
