If you need a visa or a residence permit to stay in Germany, you will have to prove that you have access to at least 992 euros per month (as of August 2024). This financial requirement is tied to the maximum student grants and loans that German nationals may be able to access (BAföG). It is not adjusted for local variations in living costs, so you must have access to the same amount regardless of whether you study in a comparatively costly city such as Munich, or a comparatively affordable city such as Passau. Of course, in a city with lower living costs, it is up to you whether you spend the entire amount.
