1500€/month after taxes sounds very low. That is like 27k yearly before taxes (Steuerklasse 1 / no church taxes). Eastern europeans get paid that, because you can lowball them so easily. But as far as I know 40k is a lower bound for cs graduates.
For reference I got 56.5k/year base salary at my first job after graduation (small company) and that were 2770€/month after taxes. I even have two friends that earn more than I do. Quit that one after half a year though (russian offshore programmers communication hell).
Your rent/food prices are correct though. Small hack: your employer can pay you 44€/month tax-free for the public transport ticket (geldwerter Vorteil Freibetrag).
