Law Of Diminishing Marginal Utility

Reviewed by Apoorva | Updated on Nov 11, 2021



The law of diminishing marginal utility says that everything, if not equal to consumption, will increase the marginal utility procured from every additional declined unit.

The marginal utility might drop down below zero to a negative utility when the situations are completely unfavourable for consuming products. Hence, the very first unit of the product has the highest consumption, and it starts falling thereafter.
