The Short Answer
If you need public health insurance in Germany, do not choose a fund by guessing which logo is “more official.” All major Krankenkassen must cover the same legal core benefits.
- About 95% of public coverage is defined by law and is the same across funds.
- What actually differs: Zusatzbeitrag (additional contribution), English-language service, apps, bonus programs, and optional extras.
- For English-speaking newcomers, Feather repeatedly positions TK as the strongest all-around public option.
- BARMER is positioned for strong English support and family-friendly extras such as a bonus program.
- DAK stands out in Feather’s materials for pregnancy extras, bonus points, and selected add-ons such as dental-cleaning support.
- AOK is highlighted for selected preventive extras such as earlier skin-cancer screening and stronger osteopathy support in Feather’s comparison.

What Is Identical Across TK, BARMER, AOK, and DAK
Feather’s public-insurance guides are clear on this point: public funds are not competing private products with totally different medical systems. They are statutory funds.
- Core doctor, hospital, prescription, maternity, and preventive benefits are largely fixed by law.
- Pre-existing conditions are covered in the public system if you are eligible to join.
- Non-working spouses and children can often be included under family-insurance rules when they meet the income and age conditions.
- Employees usually split contributions with the employer.
That is why switching funds does not mean “worse healthcare” for the legal core. It means different price, service, and extras.
How Public Insurance Pricing Works
According to Feather’s 2026 public-insurance materials:
- Base health contribution: 14.6% of gross income
- Average Zusatzbeitrag in 2026: 2.90%
- Average total health contribution rate: about 17.50%
- Contributions are calculated up to the income ceiling of €5,812.50/month (€69,750/year)
- Long-term care insurance is charged in addition
In Feather’s May 2026 cheapest-fund ranking, sample employee costs at €5,000 gross/month include:
- TK: total rate 17.29% → about €432.25 employee share
- DAK: total rate 17.80% → about €445.00 employee share
BARMER and AOK rates move over time and should be checked in the live Feather quote before you decide on price alone.

AOK: Selected Preventive Extras
Feather partners with AOK and notes in its public-insurer comparison that AOK can be attractive for specific extras:
- Skin-cancer screening fully covered from age 14, while many funds start later
- Up to €180/year for osteopathy in Feather’s comparison
- With DAK, €500 toward extra pregnancy diagnostics/ultrasounds
- If both partners are insured with AOK, Feather states artificial insemination support at 75%, versus 50% at the other compared funds
AOK is also organized regionally in practice, so branch experience can vary by location. Use Feather for English signup, then confirm local service expectations for your city.

DAK: Pregnancy Extras, Bonus Points, and Add-Ons
Feather’s DAK partner page and comparison guide highlight:
- Bonus points for preventive check-ups and immunizations, exchangeable for up to €70 cash back per year
- English-language support line with published weekday hours
- Up to €60/year toward dental cleanings
- Travel vaccinations covered up to 90%
- €500 for extra pregnancy diagnostics/ultrasounds
- Up to €500 to keep a midwife on call before the due date, versus about €200–€270 at the other compared funds
- A mental-health pathway through VeoVita for faster access in Feather’s comparison, with no guarantee of English-speaking therapists
In Feather’s 2026 cheapest ranking, DAK’s total rate of 17.80% sits above TK’s 17.29%. That makes DAK a stronger fit when specific extras matter more than the lowest available rate among the big English-friendly funds.

Which One Should You Choose?
- Choose TK if you want the strongest published English-support + digital experience and a below-average 2026 rate among large English-friendly funds.
- Choose BARMER if family cover and a cash-back bonus program are high priorities.
- Choose AOK if specific preventive extras such as earlier skin-cancer screening or osteopathy support matter to you.
- Choose DAK if pregnancy extras, dental-cleaning support, travel vaccines, or the bonus-point system matter more than a slightly higher contribution.
If you are still on a first visa and not yet eligible for public insurance, start with expat/incoming cover first, then switch when employment or student eligibility opens public membership.

How Switching Works
Feather’s switching guidance states:
- You can usually switch after 12 months with your current fund.
- If your fund raises its Zusatzbeitrag, a special cancellation right may apply without waiting the full 12 months.
- Your new insurer typically handles cancellation of the old membership.
- Standard notice is often two months to month-end.
- There should be no coverage gap if the switch is processed correctly.
