Germany's dual health insurance system is one of the best in the world — but choosing between GKV and PKV can make or break your finances. Here's everything you need to know, in plain English.
When you move to Germany, one of the first — and most consequential — financial decisions you'll face is whether to join the public health insurance system (Gesetzliche Krankenversicherung, or GKV) or opt for private health insurance (PKV). Unlike many countries where the choice is simple, in Germany it depends on your income, employment status, age, health, and long-term plans.
Get it right, and you'll enjoy excellent healthcare at a fair price. Get it wrong, and you could be locked into a costly decision for decades. We've seen expats make expensive mistakes because no one explained the system to them clearly. That's exactly why we wrote this guide.
The good news: we help expats navigate this decision every day, and the consultation is completely free. But first, let's understand how the system works.
Public health insurance is the default for about 90% of Germany's population. It's provided by roughly 100 non-profit "Krankenkassen" (sickness funds) — the biggest names for expats are TK (Techniker Krankenkasse), Barmer, AOK, and DAK. By law, all Krankenkassen must offer the same core benefits package. The differences lie in customer service quality, additional perks, and the supplementary contribution (Zusatzbeitrag), which currently averages around 1.7%.
The total contribution rate is approximately 14.6% + ~1.7% Zusatzbeitrag = ~16.3% of your gross salary (including nursing care insurance). If you're employed, this is split roughly 50/50 with your employer. The maximum contribution is capped at the Beitragsbemessungsgrenze (€5,512.50/month in 2026).
Total monthly health + nursing insurance: ~€815
Your share: ~€407/month · Employer: ~€407/month
Includes Pflegeversicherung (nursing care). Exact amounts vary by Krankenkasse and personal situation (children, church tax, etc.).
German public insurance is genuinely comprehensive. It covers doctor and specialist visits, hospital treatment, prescription medications, mental health care, maternity and newborn care, preventive screenings, rehabilitation, and sick pay (Krankengeld) after six weeks of continued salary from your employer. The main limitations: you can only see doctors who accept public insurance patients (Kassensitz), specialist wait times can stretch to weeks, and certain treatments like premium dental work, private doctor choices, or alternative medicine aren't fully covered.
For most expats, especially those with families or pre-existing conditions, public insurance offers excellent value and security. Read more about health insurance options for expats.
Private health insurance offers customizable coverage with significant advantages in terms of access and comfort — but it's only available to certain groups, and the financial structure is fundamentally different from GKV.
€77,400 / year
€6,450 / month
This threshold is adjusted annually. Earning above it means you have the option to go private — not the obligation. You can stay in public insurance even above this income.
PKV premiums are not based on your income. Instead, they depend on your age at enrollment, health status, chosen coverage level, and deductible. A healthy 30-year-old might pay €500–800/month for comprehensive coverage; basic plans start around €150/month. Your employer still pays their share (up to the maximum GKV contribution) if you're employed.
Critical point: PKV premiums increase as you age. A 60-year-old can easily pay €800–1,500/month. There's also no free family coverage — each family member needs their own policy. For families with children, this makes PKV significantly more expensive than GKV in most cases.
This is the single most important thing to understand about PKV: switching back to public insurance is extremely difficult. If you're under 55 and earned above the threshold, you generally cannot return to GKV unless your income drops below the threshold or you take a job that mandates public insurance. Even at 55+, returning requires proving you were insured in GKV for at least 24 months within the last five years — which most PKV members haven't been.
Once you're in PKV, you're in for life. And because premiums increase with age, this can become a serious financial burden in retirement. This isn't meant to scare you — PKV can be an excellent choice — but it must be an informed one.

There's no universal answer, but here are the scenarios where PKV is clearly advantageous — and where it's clearly not.
Many of these mistakes happen because expats rely on advice from colleagues or online forums rather than consulting an independent broker. We've helped hundreds of expats in Berlin avoid exactly these pitfalls — and the consultation is always free. Don't forget to also consider liability insurance, which is equally essential for expats.
