What is the recognized trade-off associated with a reusable first stage design?

A payload penalty, as extra fuel is needed for landing maneuvers.

Reusable launch systems, exemplified by rockets like SpaceX's Falcon 9, achieve cost savings by recovering and refurbishing the most expensive component, the first stage. However, this capability introduces an engineering constraint known as the payload penalty. Since the first stage must reserve a significant amount of its propellant specifically for the complex sequence of re-entry burns, attitude control adjustments, and the final propulsive landing—whether on land or a droneship—that fuel cannot be used to accelerate the actual cargo (payload) to orbital velocity. This trade-off means a reusable first stage can lift slightly less mass to orbit compared to an identical stage designed to be expendable, although the long-term economic benefits of reuse are accepted as outweighing this capacity reduction.
