Was wondering about this. With no kids, not married in Germany and 50k income before taxes, you'll pay about 500€ of public health insurance per month. Doctor visits are free, hospitals around 10€ per night, medicine with prescription will cost a fixed price of 5€. For comparison, 50 pills of Ibuprofen 400mg (no prescription necessary) cost 5€ as well. You're covered anywhere inside the EU.
