In the context of cardinal utility, economists sometimes speak of a law of diminishing marginal utility, meaning that the first unit of consumption of a good or service yields more utility than the second and subsequent units, with a continuing reduction for greater amounts. The term marginal refers to a small change, starting from some baseline level. For reasons of tractability, it is often assumed in neoclassical analysis that goods and services are continuously divisible. In practice the smallest relevant division may be quite large.

Sometimes economic analysis concerns the marginal values associated with a change of one unit of a discrete good or service, such as a motor vehicle or a haircut. For a motor vehicle, the total number of motor vehicles produced is large enough for a continuous assumption to be reasonable: this may not be true for, say, an aircraft carrier. Depending on which theory of utility is used, the interpretation of marginal utility can be meaningful or not. Economists have commonly described utility as if it were quantifiable, that is, as if different levels of utility could be compared along a numerical scale. Contemporary mainstream economic theory frequently defers metaphysical questions, and merely notes or assumes that preference structures conforming to certain rules can be usefully proxied by associating goods, services, or their uses with quantities, and defines “utility” as such a quantification. Another conception is Benthamite philosophy, which equated usefulness with the production of pleasure and avoidance of pain, assumed subject to arithmetic operation.

Though generally pursued outside of the mainstream methods, there are conceptions of utility that do not rely on quantification. In any standard framework, the same object may have different marginal utilities for different people, reflecting different preferences or individual circumstances.
