Statutory health insurance is a pillar of the German healthcare system, but do you know all the details? Many policyholders pay hundreds of euros every month without making full use of their options. This article looks at how you can understand and improve your cover.
The topic in brief and concise terms
The GKV is based on the solidarity principle: contributions are based on income, benefits are the same for everyone.
The contribution amount is determined by the general contribution rate, the individual additional contribution of the health insurance fund and the contribution assessment ceiling.
Family members can often be included in the insurance free of charge, which saves considerable costs.
Understanding the fundamentals: key principles of statutory health insurance at a glance
Statutory health insurance (GKV) has been a cornerstone of the German social security system since its introduction in 1883. Today, more than seventy million people in Germany are covered. The central principle is solidarity: contributions are based on financial capacity, while entitlement to benefits is the same for everyone. Employees, pensioners, students and, under certain conditions, self-employed people are also insured here. GKV is legally mandated to maintain or restore the health of insured persons. This fundamentally distinguishes it from private providers, where risk assessment and the scope of benefits vary individually. Understanding this basis is the first step towards optimising your cover.
Calculating contributions: How your statutory health insurance costs are made up
Contributions to statutory health insurance are calculated as a percentage of gross income. The general contribution rate is 14.6%, of which employees and employers each pay half, i.e. 7.3%. In addition, there is an insurer-specific supplementary contribution, which in 2025 averages around 1.7%. For income above the contribution assessment ceiling, which in 2025 is EUR 66,150 per year (EUR 5,512.50 per month), no higher contributions are due. Self-employed people usually pay their contributions in full themselves, but may in some cases pay a reduced rate for income up to the minimum assessment threshold of EUR 1,248.33 (as at 2025). A precise understanding of these figures helps with financial planning.
Use the service catalogue: This basic care is guaranteed
The GKV benefits catalogue is extensive and is defined by law in Book V of the German Social Code (SGB V). The core services, which make up around ninety-five per cent of the offer and are the same across all funds, include:
Medical and dental treatment, including psychotherapy.
Provision of medicines, dressings, remedies and assistive devices.
Hospital treatment, both inpatient and day-patient.
Preventive medical services and rehabilitation.
Sickness benefit in the event of incapacity for work for more than six weeks.
Statutory co-payments apply to many services, for example ten euros per hospital day for a maximum of 28 days per year. The costs for a glasses under GKV are only covered in exceptional cases. Understanding these basic benefits is crucial for identifying gaps in care.
Protecting your family: the benefits of free family cover
A major advantage of statutory health insurance is the option of family insurance at no additional cost. Spouses, registered partners and children can be covered at no extra charge, provided certain requirements are met. These include the family members having their place of residence in Germany and their total monthly income not exceeding a certain limit (2025: EUR 535 or EUR 556 in the case of a mini-job). Children are generally covered until the age of 18; in the case of school or vocational training, until the age of 25. For health insurance for children, this is an important option. Family insurance can save several hundred euros a year in contributions. This rule underlines the solidarity principle of statutory health insurance and offers families significant financial relief.
Choose a health insurer: compare extra benefits and service
Although the core benefits of statutory health insurance are around ninety-five per cent identical, there are differences in additional benefits and customer service. Many insurers offer voluntary extra benefits, such as subsidies for professional dental cleaning, alternative treatment methods or extended preventive check-ups. Changing health insurer is usually possible after a commitment period of twelve months. It is worth reviewing the offers carefully, because the level of the insurer-specific additional contribution can vary and enable savings of up to several hundred euros per year. When making your choice, pay attention not only to the premium, but also to the range of benefits that suits your needs, for example if you value insurance cover in other EU countries. Our expert tip: use comparison portals and the insurers’ advisory services. The right choice can noticeably improve your healthcare.
Deepen expert knowledge: Important sections and regulations in SGB V
The Fifth Book of the Social Code (SGB V) is the central legal basis of statutory health insurance. Some paragraphs are particularly relevant for policyholders. Section 1 of SGB V defines the tasks of health insurance, namely to maintain, restore or improve health. Section 3 of SGB V enshrines the principle of solidarity-based financing through income-dependent contributions. The requirements for contribution-free family insurance are set out in Section 10 of SGB V. Section 226 of SGB V specifies which income is subject to contributions. Recent court rulings, for example on the assumption of costs for certain therapies, can influence the interpretation of these paragraphs. In complex cases or when benefits are refused, it is advisable to refer to these principles or seek expert advice, such as our advice on voluntary health insurance. A basic understanding of the legal framework strengthens your position.
Special rules apply to certain groups of people in the statutory health insurance scheme (GKV). Self-employed people can voluntarily take out statutory health insurance if they meet certain prior insurance periods or switch directly from compulsory insurance to self-employment. Their contributions are assessed on the basis of total income, but at least on an assessment threshold of 1,248.33 euros (as of 2025). Students pay a reduced contribution until the age of 30 or the 14th semester, which in 2023 was around 110-120 euros. With a mini-job and health insurance, mini-jobbers often remain insured through a main job or family insurance, provided that the income does not exceed 556 euros. Our expert tip: Clarify your individual situation with your health insurance provider at an early stage to avoid disadvantages. These specific rules illustrate the flexibility, but also the complexity, of the system.
Unlock optimisation potential: tailored advice for your health protection
The statutory health insurance system provides solid basic cover for over seventy million people in Germany. By choosing the right health insurance fund, using bonus programmes and being aware of possible additional benefits, it is often possible to improve cover further and optimise contributions.

FAQ
What is the solidarity principle in statutory health insurance (GKV)?
The principle of solidarity means that contributions are income-dependent (those who earn more pay more), but all insured persons are entitled to the same medical benefits, regardless of the amount of their contributions or their state of health.
What is the contribution assessment ceiling?
The contribution assessment ceiling is the upper income limit up to which contributions to statutory health insurance are calculated. No further contributions are payable on income above this threshold. In 2025, it is €66,150 per year.
Which costs are not fully covered by statutory health insurance?
Statutory health insurance does not cover all costs in full. Co-payments are due, for example, for medicines, hospital stays and medical aids. Certain services, such as some vision aids or individual health services (IGeL), are often not covered at all or only covered in part.
How do I find the best health insurance provider for me?
Compare the amount of the supplementary contribution, the additional benefits offered (e.g. for dental cleaning, alternative medicine), bonus programmes and customer service. Use independent comparison portals and advisory services.
What happens to my health insurance if I become unemployed?
Recipients of unemployment benefit I or Citizen's Benefit are generally covered by compulsory statutory health insurance. The contributions are covered by the Federal Employment Agency or the Jobcentre respectively. [-ä,]
