Statutory Health Insurance (GKV) vs. Private Health Insurance (PKV): A Comparison of the Solidarity Principle and the Equivalence Principle
Introduction
The financing of healthcare in Germany is based on two fundamentally different principles. Statutory Health Insurance (GKV) and Private Health Insurance (PKV) each pursue their own approaches, which impact benefits, contributions, and financial planning. This article sheds light on the core differences between the solidarity principle of the GKV and the equivalence principle of the PKV to provide a comprehensive understanding of both pillars of the German healthcare system.
Principles in Comparison: Solidarity vs. Individuality
The Solidarity Principle of Statutory Health Insurance (GKV)
The GKV, which insures approximately 90% of the population, is based on the solidarity principle. Contributions are based on the financial capacity of the insured (income-dependent), while benefits are oriented towards medical need. In a pay-as-you-go system, current contribution revenues finance current healthcare expenses. The scope of benefits is legally defined in the Social Code Book (SGB V) and can be adjusted through political reforms. A key feature is the contribution-free family insurance.
The Equivalence Principle of Private Health Insurance (PKV)
The PKV is based on the equivalence principle. Here, contributions are based on individual risk (entry age, health status) and the chosen tariff. Benefits are individually contractually agreed upon and are guaranteed. In a funded system, a portion of the contribution is saved as reserves for old age (Alterungsrückstellungen) to stabilize contribution costs in old age. Each family member pays their own contribution.
Benefits, Contributions & Costs: GKV and PKV in Detail
Scope of Benefits
GKV: All insured individuals receive a comprehensive, legally defined catalog of benefits, which is subject to the principle of economic efficiency. The introduction of new medical procedures is regulated by the Joint Federal Committee (G-BA). In some areas (e.g., dental prosthetics, vision aids), co-payments or private supplementary insurance are common.
PKV: The scope of benefits is tariff-dependent and contractually guaranteed. Depending on the tariff, benefits that go beyond the GKV standard can be insured, such as chief physician treatment, single-occupancy rooms, or alternative healing methods. Billing according to the German scale of fees for physicians (GOÄ) creates different economic framework conditions for medical practices.
Contribution Calculation and Stability
GKV: Contributions are income-dependent up to the contribution assessment ceiling (BBG). The maximum GKV contribution for 2025 is approximately €1,218 per month (for those without children). The contribution amount is influenced by wage development, demographics, and political decisions (e.g., the level of tax subsidies).
PKV: Contributions are independent of income. Reserves for old age (Alterungsrückstellungen) (end of 2023: €328 billion industry-wide) serve to stabilize contributions in old age. Contribution adjustments are legally regulated and depend on factors such as general healthcare costs and interest rate developments.
System Change
Returning from the PKV to the GKV is only possible under certain conditions and generally only up to the age of 55. Upon switching, the accumulated reserves for old age are largely lost. Within the PKV, there is a legal right to change tariffs to adjust insurance coverage.
Recommendations for Action: Making the Right Choice
The choice between GKV and PKV is an individual decision that depends on factors such as income, professional status, health condition, and family planning.
Compare Scope of Benefits: Check which catalog of benefits meets your personal needs.
Understand Contribution Calculation: Consider how contributions and potential costs might develop in both systems over a lifetime.
Incorporate Family Planning: Weigh the advantage of contribution-free family insurance in the GKV against the model of individual contributions in the PKV.
Assess Flexibility: Familiarize yourself with the possibilities and limitations of changing systems or tariffs.
Summary and Outlook: The Future of Health Insurance
The GKV is based on the solidarity principle with income-dependent contributions and a legally defined catalog of benefits. The PKV follows the equivalence principle with risk-based contributions, contractually guaranteed benefits, and funded retirement provisions.
Both systems face challenges due to demographic change and medical progress. The GKV is more dependent on the development of the ratio of contributors to beneficiaries, while the PKV is influenced by the development of healthcare costs and capital markets. A well-informed decision requires careful consideration of one's personal situation and long-term expectations for healthcare.
