Sorry I meant that as the salary for a post-doc, which you will be for 2 (if you're top of your field) to 6-8 years (if you are a postdoc for longer, you should reconsider academia imo).

Also I meant 2000 pre-tax, but when I look at it, it seems that in some Western European countries you get paid more; like 2500-2800 pre-tax (I know several postdocs in Southern or Eastern European countries who would jump with joy with 2000 pre-tax though).

Don't think a PhD means you will earn a liveable wage! I personally know of a post-doc in economics (not paid like CS I think, but certainly normally one of the better-paid fields) who came from Eastern Europe to Belgium where he qualified for the equivalent of welfare payments ('leefloon'), which basically meant he made less than 817 euros a month!
