Methods, systems, and devices for cache block budgeting techniques are described. In some memory systems, a controller may configure a memory device with a cache. The cache may include a first subset of blocks configured to statically operate in a first mode and a second subset of blocks configured to dynamically switch between operating in the first mode and a second mode. A block operating in the second mode may be configured to store relatively more bits per memory cell than a block operating in the first mode. The controller may track and store, for each block of the second subset of blocks, a respective ratio of cycles performed in the first mode to cycles performed in the second mode. The controller may select a block from the second subset of blocks to switch between modes responsive to a trigger and based on the respective ratio for the block.
