An individual decides the demand for a good based on its utility, ie, satisfaction derived from it. But what exactly is utility? The term utility refers to the need-satisfying capacity of a commodity. There are two types of utility measures: Total Utility and Marginal Utility. Show
Total Utility refers to the total satisfaction derived from consuming a fixed amount of commodity. Marginal Utility refers to the change that arises in total utility due to the consumption of additional units of the commodity. Marginal Utility derived from the consumption of units of the commodity is interrelated with Total Utility. The phenomenon, ‘Diminishing Marginal Utility’, refers to each additional unit of gain resulting in an even-smaller increase in the subjective value. This event is known as the Law of Diminishing Marginal Utility. According to this law, a commodity’s marginal utility decreases with each successive consumption of its consecutive units. In simple words, consumption of the first unit of the commodity is higher than the consumption of the fourth unit of the commodity. For example, you have a packet of candies from which you consume three candies, which may delight your taste buds. However, after consuming nine to ten pieces, it may not be as delightful as the first three pieces consumed at the beginning Importance of the Law of Diminishing Marginal UtilityHuman wants are based on a characteristic of intensity. As we consume more of a commodity in succession, marginal utility from consumption of each additional unit of the commodity decreases. Below mentioned are some reasons that justify the importance of the Law of Diminishing Marginal Utility:
Law of Diminishing Marginal Utility examplesAs per the Law of Diminishing Marginal Utility, the marginal utility of a commodity diminishes upon the consumption of each successive unit, although total utility does not change. Here is an example of how the Law of Diminishing Marginal Utility works. A hungry man decides to purchase five chapatis. Once the man consumes the first chapati, he gains a positive utility because he was quite hungry, and the first chapati was the first thing he consumed. Therefore, the marginal utility of the consumption of the first chapati will be high. Upon eating the second chapati, the man’s appetite is further satisfied. His stomach started getting full. The man may not be as starved as he was before. Hence, the second chapati may offer less interest and relief than the first chapati. The marginal utility from consuming the second chapati may increase at a diminishing rate. Upon consumption of the third chapati, the marginal utility may diminish even more as the man’s hunger is further satisfied. Consumption of the fourth chapati may also experience even less marginal utility, and the man may feel discomfort from consuming more chapatis as his hunger is being satisfied. Finally, the consumption of the fifth chapati may not be possible as the man may feel full from consuming all the four chapatis. Hence the marginal utility from the fifth chapati may result in negative utility. With the example mentioned above, five chapatis represent the ‘Law of Diminishing Marginal Utility’, which clearly states that more and more consumption of each successive unit of commodity results in diminishing marginal utility from each additional unit of commodity consumed. In a business, a company may benefit from having two accountants. However, if there is no requirement for an additional accountant in the company, hiring one may result in diminishing marginal utility. The difference between Marginal Utility and Total UtilityMentioned below are the significant differences between Total Utility and Marginal Utility:
Law of Diminishing Marginal Utility diagram:Let’s assume that a person consumes six apples. The first apple consumed gives him 20 utils (util is a term used to measure utility). In contrast, the second and third apple consumed decreases the marginal utility with each additional apple consumed. This is because their desire to consume more apples decreases with each successive unit of apple consumed. Let’s understand this concept more clearly with the help of a schedule and diagram: Schedule for Law of Diminishing Marginal Utility:
In the schedule above, the total utility from the consumption of the first apple is 20 utils, which keeps on increasing until the person reaches their saturation point, ie, the fifth apple. On the other hand, the marginal utility from the consumption of each additional apple keeps on diminishing. Upon the consumption of the sixth apple, the person has gone over the limit, and the marginal utility becomes negative, which results in a decrease in the total utility. Here is a diagram representation based on the schedule. Types of Marginal UtilityDifferent types of marginal utilities are as mentioned below:
ConclusionThe Law of Diminishing Marginal Utility plays an important role in the economy. It directly relates to the consumption and production of goods. This law states that more of a commodity consumed will result in less satisfaction obtained from it. With the help of this law, we can conclude that, more of a commodity, goods or services consumed by a customer may result in less satisfaction derived from it, which is why the customers look for a change. This law also helps the producers design and create products according to the customers’ changing requirements.

Manage your money better What happens to marginal utility when total utility increases?(b) Marginal utility, by definition, reflects the changes in total utility. Thus marginal utility diminishes with increased consumption, becomes zero when total utility is at a maximum, and is negative when total utility declines.
How does total utility change with the change in marginal utility?If marginal utility is positive then total utility will increase. Once marginal utility is negative, then total utility will decrease.
Is the change in total utility that results from the consumption of one more unit of a product?Marginal utility is the change in total utility derived from a one unit change in consumption of a good.
What is the change in total utility called?marginal utility. the change in total utility that a consumer experiences when one more unit of a good is consumed.
