How much of my income should I spend on rent in Germany?

There is no legal rule, but two numbers matter in practice:

• Budgeting guideline: many advisors and housing offices recommend keeping warm rent (rent plus heating and service charges) at around 30 % of your net income. Above 40 % your budget becomes fragile.
• Landlord practice: private landlords commonly expect a net income of roughly three times the basic rent before they consider an application. Students usually show the blocked account, a scholarship or a parental guarantee instead.

For students the reference point is the amount the visa requires you to prove: the blocked account is based on the BAföG maximum rate (€992 per month, i.e. €11,904 per year, the figure applied by the Foreign Office for 2025 – check the current amount when you apply). A student room in Germany typically costs a few hundred euros per month, with Munich, Frankfurt, Hamburg, Stuttgart and Berlin at the top and cities in eastern Germany and the Ruhr area at the bottom; see our student rent map for the city averages and their source.

Practical advice: fix your maximum warm rent first, then search. A cheaper room in a student hall or shared flat (WG) is often what makes the budget work in expensive cities, and the Studentenwerk waiting lists are worth joining as soon as you are admitted.
