From what I hear I'd place the average for a solid experienced dev at around 40k-60k Euro per year with a pretty wide spread [1]. It's hard to tell though, I might be living in a bubble :)
[1] 3+ years, at least one larger scale project. Knowledge of more than 1 programming language
Other comments in the thread seem to fit what I'm seeing in job postings and from word of mouth. 50-60k EUR gross, maybe you can do better, maybe not. I could be totally wrong though, as the poster above me just said 40k.
If you want to make a ton of money as a programmer, the US is still where it's at IMO.
