How do you prove financial stability for a German student visa?

The main ways to prove financial stability for your student visa are either by depositing a specific amount of money into a blocked account (Sperrkonto) in Germany (make sure to verify the current required amount with the consulate) or by having a person living in Germany sign a declaration of commitment (Verpflichtungserklärung) for you. Be cautious if private universities demand high tuition fees, as this might affect the required financial proof.
