Marginal Utility Definition

Marginal utility is a term used in finance to describe the satisfaction gained by a consumer through consuming additional units of a good. For example, the satisfaction gained from eating an additional donut after eating 1 donut.

In general, the satisfaction will have diminishing returns in units consumed and sometimes negative returns. For example, most people would feel sick eating 20 donuts as opposed to 2.
