What is the Mindestbeitrag for German health insurance?

The price of public health insurance is based on your income. If you earn less money, you pay less for your health insurance.

The Mindestbeitrag is the minimum amount you can pay for health insurance. If you earn less than 1038€ per month (in 2019), the price stops going down.1

There is a different Mindestbeitrag for freelancers, the Selbstständige Mindestbeitrag. In 2019, it's around 180€1.
