Of course, like anywhere, your salary depends on your experience level, your education level, the responsibilities of your role, and the industry you're working in. As a rough estimate, I would guess that the majority of German software developers fall in the €40k-€65k salary range. My impression is that developers making €75k+ are outliers.
You also have to remember that it's hard to directly compare a German salary to an American salary. Not only is the cost of living potentially different, but the exchange rate has been moving a lot lately. Last March, €65k was $90k. Today it is only $75k.
