Health insurance in B-W, am I being ripped off?

You are in the public insurance scheme and there is no scope for being ripped off in that - especially not by AOK, the biggest public insurer.

Private health insurance can be cheaper for young and healthy people, but come with other disadvantages (e.g. you cannot insure family members for free there and it's not allowed to change back to public once you're old and the premiums rise).

The amount you mention is the normal rate, which every German resident earning above the maximum threshold ("Beitragsbemessungsgrenze") has to pay. Almost half of that is paid by your employer, the other (a bit more than) half is taken from your salary.

In the public scheme, everyone pays a certain percentage (curently around 16%) of one's income. From that, a reasonable level of health care is paid for all, regardless of what they contribute.

"Pflegeversicherung" is not for hospital treatment, but old age or disability care.

Oh, I see. So only half of it will be deduced from my salary then? That's what "subsidy" is supposed to mean?

Askthe person who wrote it, what they mean by "subsidy".

By law, the employer has to bear slightly less than half, and they are not allowed to give more (or less).
