pure savings
BKK firmus — the 2026 cost leader
- 2.18% Zusatzbeitrag — lowest of any nationwide Kasse in 2026.
- Open to everyone (not employer-restricted like some BKK funds).
- German-language portal only; claims + member service are solid but not English-first.
- Same statutory benefits package as TK/Barmer — the rate difference is pure savings for a healthy newcomer willing to lose English UX.
TK — the default newcomer choice
Why TK wins for most newcomers
- Best digital app (German + English)
- Fastest claims processing — Krankengeld typically paid within 2 weeks
- Broadest international coverage — EHIC arrives automatically
- Strong Bonuspass (€150–300/year cashback for health behaviours)
Why you might skip it
- 2.69% is mid-pack in 2026 — BKK firmus saves ~€25/month on €5k gross
- You're paying for UX you may not need if you read German fluently
- No dental full-coverage — dental top-ups (Zahnzusatz) are a separate policy
What nobody tells newcomers
You can switch Kasse after 12 months
12 mo lockSwitching is a 2-form process — the new Kasse handles everything with your old one. If you started on the wrong one, fix it after a year.
Bonus programmes add up
Most Kassen offer €150–300/year cashback for gym attendance, health check-ups, or vaccination. TK's Bonuspass is the most generous.
eGK card takes 3 weeks
3 weeksEmergencies are still covered — the Kasse issues a temporary PDF while you wait for the physical card.
Spouse co-insurance is free
If your spouse earns less than €520/month (Minijob threshold), they're free on your GKV. PKV doesn't match this.
When to consider private (PKV)
PKV makes sense only if all of: income above €77,400/year (Versicherungspflichtgrenze 2026), young + childless, willing to lose GKV family co-insurance, and OK with rising premiums in old age. Switching out of GKV is easy; switching back is nearly impossible after 55.

For freelancers
If you freelance in Germany, you pay both halves of the GKV premium yourself — on €3,000 net/month, that's ~€570/month on TK, ~€650/month on DAK. Freelancers with high income often switch to PKV — the math flips at ~€4,500 net/month.
