To give some numbers to play with, here's an official simulator for France: https://mon-entreprise.fr/simulateurs/salaire-brut-net https://mon-entreprise.fr/simulateurs/salaire-brut-net Sorry it's in French, but very simple. Choose by month or year, and you have in order: total cost (what the company pays), before tax salary (what's on the contract), "net" salary (ignore that), after tax salary (what they employee actually gets). You can see that the employee gets about half of the total employer cost.
