Here in France: I had a ~1 900€ salary after taxes (incl. income tax, 2 000€ otherwise) but because I was working in a company fulltime (the contract stated I was to devote myself 100% to my research, the reality was different but that's another topic).

My partner, on the other hand, has a public contract (with teaching charge), she gets around 1 400€ after taxes. Living with this in Paris is not easy (1 studio of 15m² will cost around 650-700€)
