Cardinal utility is a theory in economics that suggests that utility, or the satisfaction or pleasure that a consumer derives from consuming a good or service, can be measured and quantified numerically. This means that economists can assign a specific numerical value to the level of satisfaction a consumer receives from consuming a particular good or service.
The concept of cardinal utility allows economists to compare the levels of satisfaction that consumers derive from consuming different goods and services. By assigning numerical values to utility, economists can analyze consumer preferences, make predictions about consumer behavior, and make decisions about resource allocation and production.
However, it is important to note that cardinal utility is a theoretical concept and cannot be directly observed or measured in real-world situations. Instead, economists use mathematical models and assumptions to estimate and analyze utility levels. Additionally, some economists argue that utility is a subjective and individualized concept that cannot be accurately quantified in numerical terms.

Cardinal Utility of the Consumer
Cardinal utility refers to the ability to measure and compare the satisfaction or happiness derived from the consumption of different goods and services. It assumes that consumers can assign numerical values to their preferences, quantifying the utility they receive from each unit consumed.
Key Assumptions of Cardinal Utility:
- Consumers can compare and rank their preferences.
- The utility of different goods is measurable and additive.
- Consumers act rationally to maximize their total utility.
Measurement of Cardinal Utility:
Cardinal utility is typically measured on a scale known as a util. The unit of util represents the amount of satisfaction or happiness derived from consuming one unit of a particular good. For example, if a consumer assigns a utility of 10 utils to a chocolate bar, it means that the chocolate bar provides 10 times as much satisfaction as a reference point of zero utility (e.g., not consuming anything).
Properties of Cardinal Utility:
- Transitivity: Consumers can rank their preferences in a consistent and logical manner.
- Additivity: The total utility derived from consuming multiple goods is equal to the sum of the utilities of each individual good.
- Diminishing Marginal Utility: As the consumer consumes more units of a good, the additional utility derived from each subsequent unit decreases.
Implications of Cardinal Utility:
- Indifference Curves: Consumers who are indifferent between two combinations of goods are on the same indifference curve, representing the same level of utility.
- Budget Line: The budget line represents the combinations of goods that consumers can afford given their income and prices.
- Optimal Consumption: Consumers choose the combination of goods that maximizes their total utility subject to the budget constraint, represented by the point of tangency between the indifference curve and the budget line.
Criticisms of Cardinal Utility:
- It may be difficult for consumers to quantify their preferences accurately.
- The assumption of additivity may not hold true in practice.
- It assumes perfect rationality, which might not reflect real-world behavior.
Despite its limitations, cardinal utility remains a useful concept for understanding consumer behavior and predicting demand. It provides a framework for analyzing how consumers make choices and allocate their resources to achieve maximum satisfaction.
