marginal product

This term is a technical expression used primarily in economics and business management to describe the rate of change in total output. It is distinct from "marginal utility," which refers to the satisfaction gained from consuming an additional unit of a good, rather than the production of it.

In practical application, this concept is central to the law of diminishing marginal returns, where adding more of a single input eventually leads to smaller increases in output. Because it is a specialized economic term, it is almost exclusively found in formal academic texts, financial reports, and strategic business analyses.
