BKK Herkules lowered its additional contribution by 0.9 percentage points to 3.48% on 1 October 2026. It is open in Bavaria, Hesse and Lower Saxony. At €4,000 gross, members now pay €18 less per month than before – their share.
Good to know: a reduction does not give a special right of termination – that only exists when an insurer raises its additional contribution. Anyone who wants to switch to BKK Herkules can do so as usual after 12 months with their current insurer. The official average is 2.9%; benefits differ, so compare both.
