It also helps to explain why demand curves are downward sloping in microeconomic models since each additional unit of a product or service is put toward a less valuable use. Utility is the degree of satisfaction or pleasure a consumer gets from an economic act. A hungry individual can purchase a sandwich to eat so they’re no longer hungry. The law of diminishing marginal utility is based on the following assumptions.
The equation shows that as the quantity consumed increases, the marginal utility decreases. The Law of Diminishing Marginal Utility can be explained using the following example. The first slice of pizza will give you a high level of satisfaction, and you will enjoy it.
Diminishing Marginal Utility vs. Other Measurements
If the customer uses beyond this stage, marginal utility becomes negative, and total utility falls. It means that the consumer begins receiving disutility i.e., dissatisfaction instead of getting satisfaction. Since economists believe that a consumer is a rational being, s/he wants to maximize his/her satisfaction.
Indifference Curves – Falling Market Prices
Suppose there is a manufacturer who has a huge demand for his products. But eventually, there will come a point where hiring more workers does not benefit the organization. Instead, hiring more workers brings down the production per worker since the quantity demanded was being met by fewer workers.
Water – Diamond Paradox:
When the marginal utility becomes negative (6th and 7th units), the total utility declines from 50 units to 45 and then to 35 units. The law states that the additional utility or marginal utility derived from the consumption of every additional unit of a commodity goes on diminishing.The law of diminishing marginal utility is based on the two facts. The first is that human wants are limitless but, every single want is satiable for a time being.
Total Utility vs. Marginal Utility
- Thus, the consumer gets maximum satisfaction when MU is zero and that point is known as the point of saturation.
- From Table 3.1 and figure 3.1 it is very clear that the marginal utility (addition made to the total utility) goes on declining.
- Total Utility increases with consumption, but at a decreasing rate, while Marginal Utility refers to the additional satisfaction from consuming one more unit, which eventually declines.
- Should a market become quickly saturated with people who all own cell phones, a company can be stuck holding inventory.
- Notice that as we increase the number of units, the marginal utility of every additional unit falls.
As you eat more slices of pizza, the satisfaction you derive from each additional slice will decrease. You may still enjoy the second slice of pizza, but not as much as the first one. The third slice of pizza may not be as enjoyable as the second one, and so on. Eventually, you may become full, and the satisfaction you derive from each additional slice of pizza will become negative. Following this, a stage comes where marginal utility becomes zero and the total utility becomes maximum.
The shop that’s selling the pizza can avoid diminished marginal utility and encourage consumers to purchase more by diversifying its menu. Let us understand the concept first using some elementary examples of the law of diminishing marginal utility. 1 The principle of diminishing marginal utilitywas first proposed by German economist H. Gossen in 1854, and waslater refined and developed by a number of economists including British economist Alfred Marshal.
The law of diminishing marginal utility can produce a very steep drop-off. The law of diminishing marginal utility is not specific to any industry. Your appetite is becoming satisfied after you eat the second slice of pizza. You’re not as hungry as before so you experience a smaller benefit and less enjoyment from the second slice than with the first. The third slice holds even less utility because you’re only a little hungry at this point. Consumers handle the law of diminishing marginal utility by consuming numerous different goods which keeps the utility high for each of them.
Indifference Curves and Consumer Equilibrium
If you already own a cell phone, the tactics used by the salesperson will differ. A second phone for work, a backup phone, or an upgrade might be suggested. Consider an individual on a deserted island who finds a case of bottled water. That person might drink the first bottle, indicating that satisfying thirst was the most important use for the water. The second bottle might be used for bathing, and the rest might be saved for use later.
- Marshall (1920, 1961) continued this line of thinking, giving a more technical definition.
- They understand that the more a consumer consumes a good, the less satisfaction they derive from each additional unit of the good.
- The Law of Diminishing Marginal Utility has several applications in economics.
- It also helps to explain why demand curves are downward sloping in microeconomic models since each additional unit of a product or service is put toward a less valuable use.
- Consumption of a product may begin with increasing marginal utility for every unit consumed followed by decreasing marginal utility for later units.
Marginal utility is the change in the utility derived from consuming another unit of a good. The total utility (sum of utilities of all the units consumed) goes on increasing and after a certain stage begins law of diminishing marginal utility given by to decline. When the marginal utility declines and it is greater than zero, the total utility increases. For the first four units of apple, the total utility increases from 20 units to 50 units. When the marginal utility is zero (5th apple), the total utility is constant (50 units) and reaches the maximum.
The DMU law is universally applicable, and it applies to all products and services. As a result, it will be interesting to check whether Dhoni’s situation in relation to the law discussed above stands the test of time. In Dhoni’s scenario, fans have always gone the distance to get a glimpse of him batting.

Exceptions of Law of Diminishing Marginal Utility
Marginal Utility is the change in total utility due to a one-unit change in the level of consumption. The Law of Diminishing Marginal Utility states the marginal utility gradually decreases with the level of consumption, utility being defined as satisfaction or benefit. According to the Law of Diminishing Marginal Utility (DMU), with the consumption of more and more units of a commodity, the utility obtained from each successive unit decreases.
A company’s marketing strategy often revolves around balancing the marginal utility across product lines. Marketing professionals must juggle a variety of new product introductions to keep consumers interested in numerous products. For example, a consumer might buy a certain brand of chocolate for a while. Soon, they find that their enjoyment of the chocolate decreases and they will look for an alternative. Total Utility is an aggregate measure of satisfaction gained from consumption, whereas Marginal Utility is a measure of the change in satisfaction gained from consumption as a result of a change in consumption.
