When you turn 30 as a Werkstudent in Germany, your affordable GKV (public statutory health insurance) student rate of €141.16/month stops — by law. You then face three concrete options: continue in GKV as a voluntary member (roughly €230/month), switch to private health insurance (PKV, from €44/month), or check whether your employer’s social insurance setup changes anything for you. Which path makes sense depends on your income, how long you plan to study, and whether you might need a family member covered. This guide walks through every scenario with real 2026 numbers.
What changes for Werkstudents when they turn 30 in Germany?
The Werkstudent student health insurance (Krankenversicherung der Studenten, KVdS) ends at the conclusion of the semester in which you turn 30. From that point, you are no longer entitled to the subsidised student rate — even if you are still enrolled and still working fewer than 20 hours per week.
The legal basis is § 5 Abs. 1 Nr. 9 SGB V. This paragraph grants compulsory student membership in a statutory health fund (GKV) to students under 30 who are enrolled at a state-recognised university. The moment the age threshold is passed, compulsory KVdS membership expires automatically.
Here is what changes in practice:
- No more €141.16/month student rate. That figure is the KVdS contribution for 2026, calculated as 10.22% of the assessment basis (Bemessungsgrundlage) of €1,131.67, plus a reduced long-term care insurance contribution. It covers everything from GP visits to hospital stays.
- Your Werkstudent privilege survives. The social security exemption that lets Werkstudents avoid health, long-term care, and unemployment contributions on their wages does not vanish at 30. It is tied to your Werkstudent employment status, not to your age. What ends is only the KVdS rate you pay for your own coverage.
- You have roughly two weeks to decide. Your Krankenkasse will notify you when your student membership is about to end. If you do nothing, you are automatically converted to voluntary GKV membership at the higher rate.
The semester-end grace rule
The KVdS does not end on your actual birthday. It continues until the end of the semester in which you turn 30:
- Winter semester: 31 March of the following year
- Summer semester: 30 September
Example: if your 30th birthday is 4 June 2026, your KVdS continues until 30 September 2026. You gain up to six months of extra student-rate coverage — enough time to research your options without rushing.
Can I keep GKV as a voluntary member after turning 30?
Yes — you can stay in the GKV system as a freiwillig Versicherter (voluntary member). Your coverage remains comprehensive and identical to statutory membership, but the monthly contribution is significantly higher: roughly €230–€260/month in 2026.
How voluntary GKV contributions are calculated
Voluntary GKV contributions are no longer calculated on the KVdS assessment basis. Instead, they are based on your total income from all sources (salary, family support, investment income, etc.), subject to a minimum income floor:
| Basis | 2026 figure |
|---|---|
| Minimum monthly income assumed | €1,131.67 |
| Maximum income counted (contribution ceiling) | €5,512.50 |
| General contribution rate (Allgemeiner Beitragssatz) | 14.6% |
| Average Zusatzbeitrag (supplementary rate) | ~1.7% |
| Long-term care insurance (Pflegeversicherung) | 3.6% (childless); 3.025% (with children) |
If you earn less than €1,131.67/month as a Werkstudent — which is common, since many Werkstudenten work 15–18 hours per week at €15–€18/hour — the Krankenkasse still applies the minimum floor. That means you pay on €1,131.67 even if your actual income is lower.
Approximate minimum monthly cost of voluntary GKV in 2026:
- Health: 14.6% + ~1.7% = 16.3% × €1,131.67 = ~€184.46
- Long-term care (childless): 3.6% × €1,131.67 = ~€40.74
- Total minimum: ~€225–€230/month
If your Werkstudent salary is higher (e.g., €2,000/month), the contribution rises accordingly — up to the ceiling.
When voluntary GKV makes sense for a Werkstudent over 30
| Situation | Voluntary GKV worth it? |
|---|---|
| You have a pre-existing condition (diabetes, chronic illness) | Yes — GKV cannot exclude you or charge more |
| You expect to cover a partner or child as a dependent (Familienversicherung) | Yes — free family co-insurance in GKV |
| You plan to finish your degree within 12 months | Probably — simpler continuity, no re-enrolment into GKV needed after graduation |
| You earn above €3,000/month as a Werkstudent | Check carefully — contributions scale up fast |
| You are healthy, under 35, no dependents | PKV may be cheaper — see next section |
Should I switch to private insurance (PKV) as a Werkstudent over 30?
Yes — for many healthy Werkstudenten over 30 without dependents, PKV is noticeably cheaper than voluntary GKV: €44–€104/month compared to €225–€260/month. But the trade-off is real: lower coverage quality, no family co-insurance, and a difficult path back to GKV later.
The PKV options most relevant for international Werkstudenten over 30 are travel health insurance-type policies designed for foreign students (not standard German PKV, which requires a long-term contract and medical underwriting for residents).
PKV prices for students over 30 in 2026
| Provider & Plan | Monthly (age 30–40) | Co-pay | Mental health | Family co-insurance |
|---|---|---|---|---|
| MAWISTA Classic | €44 | 20% (max €250/yr) | Not covered | No |
| MAWISTA Classic Plus | €56 | 15% (max €250/yr) | Not covered | No |
| Care College Basic | €32 (first 24 mo) | €120/yr flat | Not covered | No |
| Care College Comfort | €48 (first 24 mo) | €0 | Not covered | No |
| MAWISTA Comfort | €104 | 10% (max €250/yr) | Not covered | No |
Note: Care College prices increase from month 25 (e.g., Basic rises to €55/month, Comfort to €73/month for ages 30–40).
The critical warning about switching to PKV
Once you opt out of GKV as a voluntary member to switch to private insurance, you cannot simply return to GKV while you are a student. The Befreiung von der Versicherungspflicht (exemption from compulsory insurance) is binding for the duration of your student status. The only way back into GKV while studying is via a new compulsory trigger — for example, if you start a regular (non-Werkstudent) job subject to full social insurance.
This matters especially for international students planning to work in Germany after graduation: re-entering GKV as a regular employee is straightforward, but re-entering during your remaining study years is not.
What PKV does not cover (compared to GKV)
- No family co-insurance. Partners and children must each pay a separate premium.
- No guaranteed acceptance for pre-existing conditions. Student-focused PKV products (MAWISTA, Care College, DR-WALTER) typically exclude pre-existing chronic conditions entirely.
- No psychotherapy. None of the student-focused PKV products cover outpatient psychotherapy. GKV covers it fully.
- No Krankengeld (sick pay) in most plans. GKV pays sick pay from week 7; standard student PKV policies do not.
What if my employer pays my insurance as a Werkstudent?
Your employer does not pay your health insurance as a Werkstudent — that is precisely what the Werkstudentenprivileg (working student privilege) means. Werkstudenten who work fewer than 20 hours per week during the lecture period are exempt from health, care, and unemployment insurance contributions. Only pension insurance (9.3% of gross pay from both sides) applies.
This does not change after you turn 30. The Werkstudentenprivileg is independent of your age. So:
- Before 30: employer pays nothing toward your health insurance; you pay €141.16/month KVdS yourself.
- After 30: employer still pays nothing toward your health insurance; you now pay either ~€225/month (voluntary GKV) or ~€44–€104/month (PKV) yourself.
The one exception: exceeding the 20-hour limit
If your working hours regularly exceed 20 hours per week during lecture periods, you lose Werkstudent status. The employer must then enrol you in full social insurance — including health, care, unemployment, and pension contributions. In that case:
- The employer contributes ~7.3% of your salary toward GKV
- You contribute ~7.3% + Zusatzbeitrag (~0.85%) + care insurance (1.8% if childless)
- For a salary of €2,500/month, your GKV contribution would be ~€388/month employer + ~€411/month employee = ~€799/month combined
Going over 20 hours removes your privilege and creates a full employment relationship — which may or may not suit your plans, but it is not a way to get cheap insurance.
The 140-day / 70-day rule for non-EU students
Non-EU Werkstudenten must also track the 70 working-day (or 140 half-day) annual cap on hours. This applies in semesters and semester breaks. Exceeding it during the semester triggers full social insurance. After turning 30, this rule does not change — the age threshold only affects the student health insurance rate, not the Werkstudentenprivileg itself.

How does turning 30 mid-semester work?
You do not lose your KVdS on your birthday — you keep it until the end of the semester. Then you have a short decision window before the switch becomes mandatory.
Here is the exact timeline:
- Birthday (e.g., 15 May 2026): Nothing changes immediately. KVdS continues.
- End of summer semester (30 September 2026): KVdS ends automatically.
- Notification from Krankenkasse: Usually sent 4–6 weeks before semester end. Read it carefully — it contains your deadline.
- Two-week decision window: From the date your KVdS ends, you have two weeks to opt out of voluntary GKV and choose PKV instead. If you miss this window, voluntary GKV kicks in automatically.
- PKV opt-out is binding: If you choose PKV within the window, you receive a Befreiungsbescheinigung (exemption certificate). You cannot re-enter GKV as a student after this point.
What if I am turning 30 at the start of the winter semester?
If your birthday falls in October or November (during the winter semester), your KVdS ends 31 March of the following year — giving you five or more months of student-rate coverage into the new semester. Use that time to model your costs carefully.
Extension exceptions that still apply after 30
In limited cases, the KVdS can be extended beyond 30. If you were previously in a recognised volunteer service (FSJ, FÖJ, Bundesfreiwilligendienst), spent time raising a child, or completed a second educational pathway (Zweiter Bildungsweg), you may be able to claim credit for those months. Apply directly to your Krankenkasse with documentation. Approval is not automatic, and extensions beyond 30 are rare for standard cases.
What is the best option for me? A decision guide
Use this matrix to find your situation:
| Your profile | Recommended option | Approximate cost |
|---|---|---|
| Pre-existing chronic condition (diabetes, asthma, depression) | Voluntary GKV | ~€225–€260/month |
| Partner or child to insure | Voluntary GKV | ~€225–€260/month (covers family) |
| Healthy, no dependents, finishing degree in <18 months | PKV (Care College or MAWISTA) | ~€44–€73/month |
| Healthy, no dependents, 2+ years left in degree | PKV (compare carefully vs. GKV) | ~€44–€104/month |
| High Werkstudent income (>€3,000/month) | Compare GKV vs. PKV carefully | GKV scales up; PKV stays flat |
| Planning full-time employment in Germany after graduation | Voluntary GKV (simplifies re-entry) | ~€225–€260/month |
Persona 1 — Maria, 30, healthy, 12 months left in her Master’s
Maria works 18 hours/week as a Werkstudent earning €1,800/month. She has no dependents and no chronic conditions. Her best move is Care College Comfort at €48/month for the first 24 months — saving about €180/month versus voluntary GKV. When she graduates and starts full-time work, she re-enters GKV through employment automatically.
Persona 2 — Ahmed, 31, with a partner and infant
Ahmed works 15 hours/week earning €1,600/month. His partner does not work. Under voluntary GKV, his partner and child are insured for free (Familienversicherung). Under PKV, each would need a separate policy — adding €80–€150/month per person. GKV is almost certainly cheaper overall.
Persona 3 — Yuki, 30, has type 1 diabetes
Yuki requires regular specialist visits and insulin. PKV student policies exclude pre-existing chronic conditions. MAWISTA, Care College, and DR-WALTER would all deny full coverage for her diabetes management. Voluntary GKV is her only realistic option — it covers everything from day one regardless of pre-existing conditions.
Option comparison table
| Option | Monthly cost (2026) | Coverage quality | Family insurance | Pre-existing conditions | Best for |
|---|---|---|---|---|---|
| Voluntary GKV | ~€225–€260 | Full statutory benefits | Yes — free | Fully covered | Most cases |
| PKV (Care College Basic, age 30–40) | €32–€55 | Basic (€120/yr deductible) | No | Excluded | Healthy, short stay |
| PKV (MAWISTA Classic, age 30–40) | €44 | Good (20% co-pay) | No | Excluded | Healthy, flexible |
| PKV (MAWISTA Comfort, age 30–40) | €104 | Comprehensive | No | Excluded | Healthy, want best PKV coverage |
| Employer full social insurance (>20h/week) | Shared with employer | Full statutory benefits | Yes — free | Fully covered | If you exceed 20h/week regularly |

Frequently asked questions
Does my Werkstudentenprivileg end when I turn 30?
No. The Werkstudentenprivileg — the exemption from health, care, and unemployment insurance contributions on your Werkstudent salary — is not age-dependent. It is based on your employment status (Werkstudent, enrolled full-time, working <20 hours/week during lecture periods). Turning 30 only ends your KVdS student rate; the privilege itself remains intact as long as you keep Werkstudent status.
Can I stay on my parents’ GKV after turning 30?
No. Family co-insurance (Familienversicherung) in GKV has a strict age cap of 25 (or 23 for non-working dependents). If you were ever co-insured under a parent’s GKV, that ended well before you turned 30. At 30, you are only choosing between voluntary GKV membership (your own policy) and PKV.
Do I need to tell my employer when I turn 30?
Yes — inform your employer promptly so they can update your social insurance records. If you are switching from GKV to PKV, you will need to provide a PKV membership certificate and the Befreiungsbescheinigung from your Krankenkasse. If you continue with voluntary GKV, your employer’s payroll records stay largely the same (Werkstudent exemption continues), but the Krankenkasse will update your membership status.
What happens if I miss the two-week opt-out window for PKV?
You are automatically enrolled as a voluntary GKV member. This is not a disaster — voluntary GKV gives you comprehensive coverage. However, you cannot retroactively opt out and get a refund. If you later decide you want PKV, you would need to request the Befreiung von der Versicherungspflicht separately; whether this is still possible depends on timing and your Krankenkasse. Always act within the window if you have decided on PKV.
How does the GKV Zusatzbeitrag affect my voluntary contribution?
Each Krankenkasse sets its own Zusatzbeitrag (supplementary contribution rate) on top of the statutory 14.6%. In 2026, the average across all funds is around 1.7%, but it ranges from about 1.29% (some cheaper funds) to over 2.2% (some more expensive funds). This can mean a difference of €10–€15/month between the cheapest and most expensive fund. Our GKV Calculator shows current Zusatzbeitrag rates across 15+ funds so you can compare before committing.
Can I still use the GKV calculator if I am already over 30?
Yes. The GKV Calculator calculates voluntary GKV contributions based on age and income — it works for both the student rate (KVdS) and the voluntary rate (freiwillige Versicherung). Select your age and income to see the exact monthly cost across major funds.
Is Care College or MAWISTA accepted by German universities for enrolment purposes?
Yes, both Care College and MAWISTA are accepted by German universities as proof of health insurance for enrolment (Immatrikulationsbescheinigung). However, note that these are private (PKV-type) policies — if your university or visa authority specifically requires GKV membership confirmation, you must use voluntary GKV instead. Confirm with your university’s Studierendensekretariat if unsure.
