What Is Total Utility?

Total utility is the aggregate satisfaction that a consumer receives when they consume a product or service. Put simply, it is the total happiness that consumers derive from goods and services. Total utility is often compared to marginal utility, which is the satisfaction a consumer receives from consuming one additional unit of a good or service. Total utility helps economists understand the demand for goods and services.

Understanding Total Utility

Utility refers to the satisfaction gained from consuming a product or service. Total utility is usually defined as a quantifiable summation of satisfaction or happiness obtained from consuming multiple units of a particular product or service.

Utility and total utility are used in the economic analysis of consumer behaviors within a marketplace. Economists seek to quantify total utility using special calculations. Economists may also study several economic metrics in conjunction with total utility when seeking to understand how consumer behaviors align with 澳洲幸运5官方开奖结果体彩网:supply and demand.

Economists typically view changes in behavior and consumption by analyzing marginal increases and decreases. Marginal changes will usually be either scaled increases or decreases. In the case of total utility, marginal refers to the increasing or decreasing level of utility that is obtained with added consumptions.

Total Utility and the Rational Choice Theory

The 澳洲幸运5官方开奖结果体彩网:rational choice theory says that consumers seek to maximize their utility with each unit of consumption. Consumer theory and 澳洲幸运5官方开奖结果体彩网:demand theory suggest that consumer actions are driven toward utility maximization by attempting to acquire the most satisfaction possible in the most affordable way. Classical economic theories generally show that most consumers want to get the highest possible level of utility per unit for the money they spend.

Total utility is usually measured in relative units called utils, which hypothetically measure satisfaction or utility. When measuring total utility, analysis can span from one unit of consumption to multiple units. For example, a cookie provides a level of utility as determined by its singular consumption, while a bag of💜 cookies may provide total utility over the time it takes to completely consume every cookie in the bag.

The Law of Diminishing Marginal Utility

To better understand total utility, one must understand the law of diminishing marginal utility, which states that as more of a single good or service is consumed, the additional satisfaction drops. This is referred to as marginal utility.

The first good consumed provides the highest utility, the second good has a lower marginal utility, and so on. Therefore, total utility grows less rapidly with each additional unit consumed of the same good or service.

How to Calculate Total Utility

Each uni🍃t of a product or service has its own utility and each additional unit of consumption will have a separate marginal utility. The total utility will be the aggregated su😼m of utility gained from all units being studied.

A total utility formula will include utils. Utils are typically relative a𝐆nd assigned a base value. Economists usually analyze utils across a spectrum to provide a comparative analysis of the amount of util or satisfaction gain𒉰ed from a unit of consumption. An assigned base value for utils is needed because theoretically there is no real value for utility satisfaction in general.

To find total utilit🌜y economists use the following basic total utility formula:

• TU = Total Utility
• U = Utility
• MU = Marginal Utility

The total utility is equal to the sum of utils gained from each unit of consumption. In the equation, each unit of consumption is expected to have slightl♊y less utility as more units are consumed.

Total Utility Maximization

Economic theory regarding consumer activities suggests that the primary goal of the consumer is to achieve the largest amount of utility for the least amount of cost. This is partly due to the limited amount of funds a person may possess, as well as a desire to achieve as much satisfaction from the consumption of goods and services as possible.

For example, if a consumer is presented with two purchasing options with the same fina𒊎ncial cost, and neither option is more necessary or functional than the other, the cons🌳umer will choose the product or service that provides the most utility for the money.

Example of Total Utility

John is hungry and decides to eat a chocolate bar. His total utility from eating one chocolate bar is 20 utils. He is still hungry so he eats another chocolate bar🧜, where his total utility is 25 utils. John is still hungry and has two more chocolate bars. The third chocolate bar has a total utility of 27 utils, and the fourth has a total utility of 24 utils. This is best represented in the table below.

With each additional chocolate bar, John's total utility increases, until it reaches its max at three chocolate bars. With the fourth chocolate bar, John's total utility decreases. This can be understood with marginal utility; the utility that John derives from each additional chocolate bar.

With every additional chocolate bar after the first, John's marginal utility is decreasing, meaning that he is deriving less satisfaction from another chocolate bar. This makes sense as he is getting more full with each bar. After the third bar, his marginal utility is negative, meaning he is deriving no satisfaction and in fact is made worse off; perhaps feeling sick after consuming so much chocolate and sugar.

The Bottom Line

Total utility measures the aggregate satisfaction from a specific quantity of goods or services. It operates h꧒and in hand with marginal utility, which measures the additional satisfaction rece✱ived from the consumption of a good or service. As long as marginal utility is positive, total utility will increase. Once the marginal utility is negative, then the total utility will decrease.

Economists aim to study total utility and marginal utility to understand consumer behavior. Consumer behavior helps to predict the demand for goods and services, which impacts supply and prices—all key metrics of analyzing an econom♎y🤪.
