Relationship Between Total Utility and Marginal Utility:The relationship between total utility and marginal utility can be explained by the help of the following schedule:Units of orange Show
Total utility Marginal utility 0 0 0 1 8 8 2 14 6 3 18 4 4 20 2 5 20 0 6 18 -2 In the above schedule, we can see that when a consumer consumes additional units of orange then the total utility inclines at first at an increasing rate, remains constant for some period and then starts declining. With additional consumption of oranges, marginal utility declines, reach zero and become even negative. It can also be expressed by the following diagram:  From the above schedule and diagram, we can summarize the relationship between Total Utility and Marginal Utility as follows :
Total Utility and Marginal Utility are the terms that we are all familiar with from the subject of Economics. Both the terms are extremely important, not only for the students to learn, but also to know about the usefulness of a commodity. While this might come off as a completely new set of terms for some people, these are, however, one that many are well acquainted with. It is a very important part of understanding the two, that the students not only know their definition but also what difference between marginal utility and total utility. Difference between Total Utility and Marginal UtilityBasis of Difference Total Utility Marginal Utility Definition It is the aggregate of satisfaction or utility that a consumer derives from the consumption of multiple units of a specific commodity. Marginal utility meaning, the change in the total utility of a commodity due to the consumption of an additional unit of a commodity. Trend It increases with increment in the number of units consumed. According to the law of diminishing marginal utility meaning, MU declines with an increase in consumption of a particular commodity. Expression TUN = MU1 + MU2 + MU3 ... MUN MU = TUN – TUN-1 End result The total utility does increase, but as diminishing results as each unit are added to the mix. Marginal Utility also increases with diminishing results, which may also go negative or zero at some point. Positive/Negative Outcome Total Utility will always show a positive outcome, no matter what. The marginal utility cannot always be positive. It may even turn out to be negative or zero. Point of satisfaction At the satisfaction point, total utility is always maximum. At the satisfaction point, Marginal utility is always zero. Similarity Between Total Utility and Marginal UtilityOne similarity between Total Utility and Marginal Utility is the fact that these are both useful to economists. These essentially help them in understanding the consumer behavior pertaining to a single commodity - good or service. This is a way to identify whether or not there needs to be a change or advancement to the commodity they are offering. More About the TopicUtility, in general, means the usefulness of a good or service. In the Economics context, utility is more precisely defined as the satisfaction – actual or expected – that a consumer derives from using or purchasing a commodity. In recent practice, utility is represented primarily in numerical value. In the 1300s and 1400s, Spanish economists considered only the qualitative usefulness of commodities, which would allow them to determine the prices for various goods and services. This concept went through multiple phases of change, from the ordinal model to the cardinal model. These economic theories concerning utility combined with the assumption that every rational consumer would strive to maximize his/her utility from a particular product, thus, form the basis for determining demand and consequently their price. There are three ways utility is expressed in Economics – total utility, average utility, and marginal utility. The difference between total utility and marginal utility alongside their corresponding relationship are crucial topics in senior secondary Economics and require an in-depth understanding of their intricacies. Therefore, prior to beginning with distinctions between these two ideas of utility, it is quintessential to learn about those individually. What is Total Utility?Total utility (TU) is the whole amount of fulfillment that a consumer derives from the consumption or purchase of multiple units of a particular commodity, within his/her fixed income level and budget. A total utility example would be, one unit of a chocolate bar provides you with a utility of 10 utils; on the 2ndunit you receive 8 utils worth of satisfaction; the 3rd unit provides a utility of 5 utils. Therefore, the TU you derived from the consumption of three chocolate bars is 23 utils (10 + 8 + 5). Utils is the standard unit for measuring utility. It is a relative unit as utility derived from the consumption of a particular product will differ from one individual to another. For this purpose, economists suggest the usage of monetary denominations in lieu of utilization for more effective quantification. What is Marginal Utility?Marginal utility definition Economics would be the change in total utility due to the consumption of one additional unit of a commodity. In other words, it is the utility one derives from the consumption of an individual unit rather than in whole. Hence, if considering the above example, the 10 utils from the first chocolate bar, 8 utils from the second bar, and 5 utils from the third bar can be represented as the marginal utility of that chocolate bar. Derivation of MU is crucial to economic practice since it lends an idea about a product’s demand for an individual consumer. A marginal utility example would help in understanding the above statement more clearly. Upon consumption of one unit of product X, you derive 20 utils of satisfaction. On to the next unit, you derive 15 utils of utility. It goes on till the 6th unit when additional utility derived from the consumption of one extra unit has come down to zero, i.e. MU = 0. A rational consumer would stop his/her consumption at this point since he/she is not deriving any extra satisfaction. Therefore, the demand for product X for you would be 6 units. This phenomenon of gradual declination in MU is known as the law of diminishing marginal utility. According to this law of marginal utility, the first unit would provide the highest level of utility and then as consumption increases, marginal utility declines. The primary differences between TU and MU are discussed in the table below. What is the Relationship Between Total Utility and Marginal utility?The relationship between TU and MU can be properly understood through the table beneath. Here, we are assuming that the consumer is rational and expects utility from the consumption of coffee. Each unit is a cup of coffee. No. of units (cups) Total utility (TU) Marginal utility (MU) 1 30 utils 30 utils 2 55 utils 25 utils 3 75 utils 20 utils 4 85 utils 10 utils 5 92 utils 7 utils 6 95 utils 3 utils 7 95 utils 0 util 8 90 -5 utils We can see that both TU and MU began from the same point. However, as consumption increased, total utility continued increasing, whereas, the marginal utility kept declining in line. On the 7th unit, when total utility is at its peak (95 utils), the marginal utility was zero, therefore, implying that any additional cup of coffee from that point would result in negative MU or dissatisfaction. A rational consumer would stop his/her consumption at the 7th unit. Thus, from the above discussion, we can encapsulate the relationship between TU and MU as noted below –
From a consumer’s perspective, the marginal utility can be aligned with the cost of consuming a commodity. For instance, if the marginal utility cost of a commodity is Rs.20 and MU derived from it is more than 20 utils (assuming Re.1 = 1 utils), then such individuals will continue his/their consumption until the marginal utility of that commodity equals its price. It is also known as the consumer’s equilibrium. While this is one topic from Economics, multiple such topics require a thorough understanding, since memorizing this subject does not cut it if you want to ace your exams. For that purpose, you can refer to Vedantu’s study materials and online live classes. What is the relation between marginal utility and total utility?Total utility operates hand in hand with marginal utility, which measures the additional satisfaction received from the consumption of a good or service. As long as marginal utility is positive, total utility will increase. Once marginal utility is negative, then total utility will decrease.
What is the relation between total utility and marginal utility class 11th?The relationship between total utility and marginal utility indicates that when marginal utility decreases, total utility increases at a decreasing rate, and when total utility is at a maximum point, marginal utility is zero and total utility starts to decline if marginal utility is negative.
What is the relationship between TU and MU?As long as MU (marginal utility) is positive, the TU (total utility) increases with an increase in the consumption of a commodity. As MU from each successive unit diminishes, at that time TU increases but at a diminishing rate. When TU is maximum, the MU reaches zero.
Which of the following is true about the relationship between total utility and marginal utility?The correct answer is (d) Marginal utility can decline as total utility rises.
