I got an offers as a freelancer to work from Germany (the company is not German but I will live in Germany when I'll work for them). Since I'll be a freelancer in need to give them an hourly rate for my work, for that I'd like to estimate the net salary programmers here get. I found this calculatror https://www.brutto-netto-rechner.info/gehalt/gross_net_calculator_germany.php it has few options though that I don't how to fill, all in the insurance section. I'd like to know what is the common case in Germany, do employees usually get a compulsory insurance in all sections (health/ pesnsion/ unemployment) ? Also I'd be happy if people share their percentage of Net income from the gross salary so I can have a rough estimation.
