There is no cost for researchers to register with the All of Us Research Program and to begin working within the dataset. Researchers will incur costs for computation and data storage, however.
The All of Us Research Program provides $300 in initial credits for each registered Researcher Workbench user. Additional charges must be covered by the researcher through their billing accounts. Resources to help researchers estimate costs are provided within the Researcher Workbench itself, on the User Support Hub. Researchers can find examples of how much genomic data can cost to analyze in the User Support Hub (login required).
