The additional contribution to statutory health insurance will noticeably increase in 2025. Many insured individuals wonder what this means for their wallet and how they can respond. This article explains the background and provides specific action recommendations.
The topic in brief and concise terms
The average supplementary contribution to statutory health insurance will rise to 2.5 per cent in 2025, with each fund setting its own rate individually.
If the additional contribution is increased, insured individuals have the right to terminate their contract early and switch to a less expensive health insurance provider.
Since 2019, employees and employers have each shared the additional contribution equally.
Additional Contribution 2025: An Overview of the Key Facts
The average supplementary contribution rate in statutory health insurance (GKV) has been set at 2.5 percent for the year 2025. This represents an increase of 0.8 percentage points compared to the previous year, when it was 1.7 percent. Each health insurance fund determines its own individual supplementary contribution based on its financial situation. The range of fund-specific supplementary contributions in 2025 is expected to be between 2.18 percent and 4.4 percent. For insured individuals, this means that the cost of health insurance can vary significantly depending on the chosen fund. This development makes a comparison of health insurance funds even more important.
Practice Check: How the additional contribution affects your wallet
The increase in the additional contribution has direct effects on your net income. Assuming your gross income is 3,500 euros per month, with an average additional contribution of 2.5 percent in the year 2025, you and your employer each pay 1.25 percent. This corresponds to a monthly additional contribution of 28 euros more compared to an additional contribution of 1.7 percent in 2024. Over the year, this amounts to 336 euros more. Many insured individuals underestimate this annual additional burden.
The calculation is based on your contribution-assessable income up to the contribution assessment ceiling. In the year 2025, this is set at 5,512.50 euros gross per month. If you earn more, the absolute contribution to health insurance does not increase further beyond this point. It is advisable to carefully check the contribution amount.
Here is an example list to illustrate the monthly additional costs for employees due to the increase in the average additional contribution by 0.8 percentage points:
At 2,000 euros gross income: 8 euros more per month.
At 3,000 euros gross income: 12 euros more per month.
At 4,000 euros gross income: 16 euros more per month.
At 5,512.50 euros (contribution assessment ceiling): 22.05 euros more per month.
These figures illustrate how percentage changes directly impact your finances. A closer look at offers and possibly a supplementary health insurance can be worthwhile.
Expert Knowledge: Legal Foundations and Current Developments
The additional contribution was introduced to provide health insurance funds with more flexibility in financing their expenditures. The legal basis is § 242 of the Social Code Book V (SGB V). Accordingly, health insurance funds can levy an income-dependent additional contribution if the allocations from the health fund are insufficient to cover the forecasted expenses. Since 1 January 2019, the additional contribution has been equally shared by employees and employers. Previously, insured individuals had to bear it alone.
An expert panel, known as the 'Schätzerkreis', annually evaluates the financial development of the statutory health insurance and provides a recommendation for the average additional contribution rate. The Federal Ministry of Health then officially determines this. For certain groups of people, such as trainees with an income up to 325 euros, this average rate is binding. The contribution assessment ceiling caps the income on which contributions are levied.
Our expert tip: If your health insurance fund increases the additional contribution, you have a special termination right. You can then cancel your membership until the end of the month for which the increased contribution first applies and switch to a cheaper fund. The notice period is generally two months to the end of the month. Reviewing private supplementary insurance can also be an option.
Design Options: How You Can Respond to Increasing Additional Contributions
In the face of rising supplementary contributions, it's important to take action. The first and often most effective measure is changing health insurance providers. For instance, with a gross income of 4,000 euros monthly, switching from a provider with a supplementary contribution of 4.4 percent to one with 2.18 percent can mean an annual saving of over 530 euros for the employee's share. Many insured individuals do not use their special termination rights when contributions increase.
The following steps will help you optimise:
Check the current supplementary contribution of your health insurance provider.
Compare this with the offers of other providers (a list is often available online, e.g., at Krankenkassen.de ).
Pay attention not only to the contribution but also to additional benefits that are relevant to you, such as subsidies for dental cleaning or bonus programmes.
Use your special termination rights when contributions increase.
Sign up with the new provider; they usually handle the termination with your old provider.
Remember that a voluntary health insurance also offers options. For comprehensive advice on your individual situation, we at nextsure are happy to assist you.
The additional contribution and special life situations
The handling of the additional contribution has particularities for different groups of people. For pensioners, for example, the additional contribution is also borne equally by them and the pension insurance based on their statutory pension. For other income, such as rental income, they bear the additional contribution alone. For the self-employed who are voluntarily insured under the statutory system, the rule is: They pay the entire contribution themselves, which includes the general contribution rate of 14.0 or 14.6 percent plus the full additional contribution specific to the insurer. Here, the financial burden of a high additional contribution can be particularly significant.
Students pay a reduced contribution until the completion of the 14th semester or until the age of 30, which also includes the insurer-specific additional contribution. Recipients of citizens' income or trainees with earnings up to 325 euros generally only pay the average additional contribution. It is therefore important to know your own situation well to assess the costs correctly or to consider whether private health insurance for civil servants is an alternative.
Future Outlook and Final Recommendations
The financing of statutory health insurance remains a challenge. Rising healthcare costs, due to medical advances and an ageing population, suggest that pressure on contribution rates, including the additional contribution, will persist in the coming years. Experts anticipate further adjustments. A proactive approach to managing your insurance costs is therefore essential.
Our recommendation is therefore: Regularly review your health insurance situation, at least once a year or when a contribution increase is announced. Use comparison portals and pay attention to the overall package of contribution amounts and services offered. Information on how to claim your health insurance contributions in your tax return is also useful.
