in Munich: starting salaries with a masters are 55-60k€ (before tax!) at average car related companies (even for non-CS-grads doing SWE with a physics/math background), 60-70k€ at the actual car companies. Social sciences/other jobs with masters: 42-50k€, below that with a bachelors/apprenticeship. Independent of the education in IT you should be able to reach 50k after 5 years (excluding grunt work) and 80k with a masters. Some engineers I know have been taken by electronics industry as PMs for 120k€ straight out of grad school. Rents are high (20€/m²), so other parts of Germany might be better overall (subtract 20-30% of salaries).

All this doesn't hold true for a lot of immigrant labor and people working at startups, where you are offered 30-40k€ with a masters (these kindd employ most of the immigrant labor I think - of course there's the odd 100k YC). Imho this (at current rent levels) is exploitation and something which makes working in Munich not particularly attractive for anyone not from Germany or getting a job at a car company.
