For PMI it's 204, but VIE/SZG 281 sectors. I was only considering VIE/SZG when answering your post.
For VIE/SZG you can expect around 2.000 net per month (or 2.500, if you consider the two additional salaries) which already include 281 sectors. For every additional sector you'll get 50 EUR (before tax and social insurance). I don't wanna argue about whether this is a good or bad contract - everyone needs to decide in his/her own; I just wanted to clarify that the sector pay is only for additional sectors and not from sector 1 on.
