A marginal value is a value that holds true given particular constraints, the change in a value associated with a specific change in some independent variable, whether it be of that variable or of a dependent variable, or the ratio of the change of a dependent variable to that of the independent variable.. In the case of differentiability, at the limit, a marginal change is a mathematical differential, or the corresponding mathematical derivative; these uses of the term “marginal” are common in economics, result from conceptualizing constraints as borders or as margins. The sorts of marginal values most common to economic analysis are those associated with unit changes of resources and, in mainstream economics, those associated with infinitesimal changes. Marginal values associated with units are considered because many decisions are made by unit, marginalism explains unit price in terms of such marginal values. Mainstream economics uses infinitesimal values in much of its analysis for reasons of mathematical tractability.

Assume a functional relationship y = f If the value of x i is discretely changed from x i, 0 to x i, 1 while other independent variables remain unchanged the marginal value of the change in x i is Δ x i = x i, 1 − x i, 0 and the “marginal value” of y may refer to Δ y = f − f or to Δ y Δ x = f − f x i, 1 − x i, 0 If an individual saw her income increase from $50000 to $55000 per annum, part of her response was to increase yearly purchases of amontillado from 2 casks to three casks the marginal increase in her income was $5000 the marginal effect on her purchase of amontillado was an increase of 1 cask, or of 1 cask per $5000. If infinitesimal values are considered a marginal value of x i would be d x i, the “marginal value” of y would refer to ∂ y ∂ x i = ∂ f ∂ x i (For a linear functional relationship y = a + b ⋅ x, the marginal value of y will be the co-efficient of x and this will not change as x changes. However, in the case where the functional relationship is non-linear, say y = a ⋅ b
