In 2021, the total income of ZIB comprised 24.4 million euros. The main part of this was made available by the Federal State of Berlin as the basic financial stock of ZIB (14.4 million euros) including investments as well as the budget of the NHR center at ZIB (4,7 million in 2021, made available by the Federal State of Berlin but co-funded by the federal government and the German Federal States participating in HLRN). 

The second largest part of the budget resulted from third-party funds (8.1 million euros) acquired by ZIB from public funding agencies (mainly DFG and BMBF) and via industrial research projects. This was complemented by a variety of further grants, such as the research service budget of KOBV, summing up to almost 1.7 million euros in total.
