hi ray, thanks for putting up with our questions!
so for a 2nd year pre-experienced bachelor i pieced together the following:
13 months*4,2k€=54,6 brut x 0,76 (=24%tax)= 41,5k net
+
180 per diems x 100€ *0,9 (the 10,55% social)= 16,2K
+
Night & Sunday 10,5 months (rest=vacation)*500*0,9 (social)= 4,725
grand total per year == 62,4 net :12= 5,2 per month
Ehm, no.
More like:
13 months*(4200€ -
915,70€ tax - 443,1 social sec etc.)= 36935,60
+
180 per diems x 100€ (free of everything) = 18,0K
+
Night & Sunday 10,5 months (rest=vacation)*500*0,8945 social sec etc.= 4696,125
grand total per year == 59631,725 net : 12= 4969,31 per month

Classe d'impôt means: 1/0 for bachelors, 2/0 married, 2/1 married - one child, 2/2 married - two children.
But again, over 600hrs and 3500tt you'll have a basic of around 5000. In turn, since your basic salary increases, your "special" hours will give you more as well.
