No tuition fees
In Berlin all university tuition fees are covered by the state. Therefore, Master’s students of the Berlin School of Mind and Brain do not pay tuition fees.
There are no tuition fees payable for this program. However, at the beginning of each semester (summer semester: April–September, winter semester: October–March) the university matriculation fee will have to be paid to Humboldt-Universität zu Berlin.
The matriculation fee for Master’s students are currently (summer semester 2021) set at 315.64 Euro per semester (= six months). They consist of an administrative fee (50 Euro), contributions to the student union and student facilities (9.75 Euro + 54.09 Euro) and the public transport travel pass for Berlin and Potsdam (201.80 Euro, obligatory for Bachelor’s and Master's students).

Private liability insurance (Privathaftpflichtversicherung)
It is highly recommended that students and visiting researchers take out a personal liability insurance.
The website “How to Germany” writes: “The most important and yet the least expensive insurance cover you will need in Germany is private liability insurance (Privathaftpflichtversicherung). It will provide cover to you or to any insured member of your family in the event that you commit an act for which a German court would consider you ordinarily negligent. Ordinary negligence could be a simple matter of damaging someone else’s property, for instance knocking over a vase while visiting a friend or in a shop, or causing an accident as a pedestrian by not crossing at the zebra crossing, causing bodily injury whilst engaging in sports activities.”
Third-party private liability insurance costs only around 38–50 euro per year, i.e. 3–4 euro per month. The cost of one mensa meal per month could save you literally millions of euros.

Berlin is very popular, and as a result prices are rising and housing has become much more costly and hard to come by over the past few years. Master’s students should calculate at least 1,000 Euro per month for housing, subsistence, the university's administrative fees (once a semester; they include public transport, see above), and insurances.
