What is the English equivalent of "ball park figure" in financial terminology?

The term "ballpark figure" refers to an approximate estimate rather than a precise calculation. In financial contexts, it typically conveys a rough estimate or a general idea of costs involved in a project.

This is useful for initial discussions or planning phases, where exact numbers may not yet be available but a general idea of financial expectations is necessary.
