Wages usually depend on experience and age and time that you work for the company.

Yes, I would say Snoopy is about right, maybe 10% too low (but that also depends on the area one lives in in Germany).
However, it is very misleading to ask for what the netto wage is.
On one hand there are a lot of deductions, taxes, health insurance, pension insurance and the lot.
So from monthly earnings of, lets say, 4500€ you have around 2500 to 2600€ that will be left over. And, of course, it depends on how high the costs of living are and they are now low in Germany, not at all.
I would say, for example, in the US or in England people might have more from their wages than in Germany.
