The law of equimarginal returns states that a rational consumer will allocate their resources in such a way that the marginal utility (satisfaction) obtained from the last unit of each good consumed is equal. In other words, a consumer will maximize their total utility by spending their money on different goods in such a way that the additional satisfaction gained from consuming one more unit of each good is the same.
For example, if a consumer has $10 to spend and is deciding between buying apples and oranges, the consumer will allocate their money in a way that the marginal utility of the last dollar spent on apples is equal to the marginal utility of the last dollar spent on oranges. This ensures that the consumer is getting the most satisfaction possible from their limited resources.
The law of equimarginal returns is based on the assumption that consumers are rational and seek to maximize their utility. It helps explain how consumers make decisions about how to allocate their resources in order to achieve the highest level of satisfaction.

Law of Equimarginal Returns
The law of equimarginal returns is a principle in microeconomics that states that a rational consumer allocates his limited income among different goods and services in such a way that the marginal utility derived from each good or service is equal. In other words, the consumer maximizes their overall satisfaction by distributing their budget so that they get an equal amount of additional satisfaction (marginal utility) from each unit of each good or service.
- MU_i is the marginal utility of good or service i - P_i is the price of good or service i - n is the number of goods and services
Explanation:
- Diminishing Marginal Utility: As a consumer consumes more of a particular good or service, the additional satisfaction they receive from each additional unit (marginal utility) decreases. - Budget Constraint: Consumers have limited income and must allocate it efficiently to maximize their satisfaction. - Optimal Allocation: By allocating their budget so that the marginal utility per dollar spent on each good or service is equal, consumers achieve the greatest overall satisfaction.
Implications:
- Consumers should not spend more on a specific good or service if they can purchase a different good or service that provides them with equal or greater marginal utility at a lower price. - The law of equimarginal returns helps explain why consumers may choose to purchase a variety of goods and services rather than consuming large quantities of just one or a few items. - It provides a framework for analyzing how consumers make rational consumption decisions to maximize their satisfaction within their budget constraints.
