Difference Between Cardinal and Ordinal Utility (With Examples)
Utility refers to the degree of satisfaction or pleasure that a consumer derives from consuming goods and services. Since satisfaction is psychological in nature and cannot be observed directly, economists developed different approaches to analyze it indirectly.
In economics, two main approaches are used to measure consumer behaviour utility:
- Cardinal Utility – Utility can be measured numerically
- Ordinal Utility – Utility cannot be measured numerically, but preferences can be ranked
Learn the difference between cardinal and ordinal utility in economics with definitions, examples, comparison table, and why ordinal utility is more realistic in consumer behavior analysis.
Understanding the difference between cardinal and ordinal utility is essential for students studying microeconomics and consumer behavior.
What Is Utility in Economics?
Utility refers to the satisfaction or benefit a consumer derives from consuming a product or service. Economists use utility as a tool to understand consumer choices and market demand.
Because satisfaction differs from person to person and cannot be measured directly, theoretical models are used to explain marginal utility consumer behavior.
What Is Cardinal Utility?
Cardinal utility assumes that satisfaction can be measured quantitatively in numerical terms. According to this approach, consumers can express satisfaction using hypothetical units called utils.
This approach was developed and popularized by Dr. Alfred Marshall and other classical economists.
Definition of Cardinal Utility
Cardinal utility is a quantitative measure of satisfaction in which utility derived from consumption can be expressed in numerical units (utils).
Key Features of Cardinal Utility
- Utility is measurable in numerical units (utils)
- Comparison of magnitude of satisfaction is possible
- Mathematical operations like addition and subtraction can be applied
- Based on the Law of Diminishing Marginal Utility
- Assumes utility can be measured objectively
Example of Cardinal Utility
If a consumer gains 100 utils from an iPhone and 60 utils from a smartwatch, the iPhone provides 40 utils more satisfaction.
What Is Ordinal Utility?
Ordinal utility states that satisfaction cannot be measured numerically. Instead, consumers can rank their preferences based on satisfaction.
This approach was developed by Hicks, Allen, and Pareto and forms the foundation of modern consumer theory.
Definition of Ordinal Utility
Ordinal utility is a qualitative approach in which consumers rank goods according to preference without assigning numerical values.
Key Features of Ordinal Utility
- Preferences are expressed through ranking
- No numerical measurement of satisfaction
- Uses indifference curve analysis
- Utility is measured subjectively
- More realistic than cardinal utility
Example of Ordinal Utility
A consumer prefers coffee over tea and tea over juice, but we do not know how much more coffee is preferred than tea.
Difference Between Cardinal and Ordinal Utility
| Basis | Cardinal Utility | Ordinal Utility |
|---|---|---|
| Nature | Quantitative | Qualitative |
| Measurement | Measured in numbers (utils) | Cannot be measured numerically |
| Preference | Measures degree of satisfaction | Ranks preferences |
| Mathematical Operations | Possible | Not possible |
| Main Tool | Marginal Utility Analysis | Indifference Curve Analysis |
| Economists | Alfred Marshall | Hicks, Allen, Pareto |
| Realism | Less realistic | More realistic |
Why Ordinal Utility Is More Realistic
Ordinal utility is considered more realistic because satisfaction is psychological and cannot be measured in exact numbers. Consumers naturally rank their preferences rather than calculating imaginary units of satisfaction.
For example, consumers say:
- "I prefer Product A over Product B"
- Not "I get 20 utils more from Product A"
Conclusion
Both cardinal and ordinal utility are important concepts in economics. Cardinal utility attempts to measure satisfaction numerically but is largely theoretical. Ordinal utility focuses on ranking preferences and is more practical and realistic.
Understanding the difference between these two approaches helps students, economists, and policymakers analyze consumer behavior and market demand more effectively.
| Ordinal Utility | Cardinal Utility |
|---|---|
| Consumer derived satisfaction after consumption of products evaluation done without using number. | Consumer derived satisfaction after consumption of products evaluated in numerical numbers |
| Ordinal utility used qualitative approach during analysis of degree of satisfaction. | Cardinal utility used quantitative approach during analysis of degree of satisfaction. |
| Consumer in ordinal utility rank of preference according to their derived satisfaction after consumption of products. | Consumer in cardinal utility makes measurements of degree of satisfaction derived after consuming products in utils. |
| Indifference curve analysis used for explanation ordinal utility. | Marginal utility analysis used for explanation of cardinal utility. |
| Ordinal utility measurements promoted by modern economist | Cardinal utility measurement promoted by traditional economist. |
| Ordinal utility measurements results considered as more realistic. | Cardinal utility measurement results considered not realistic in comparison with ordinal utility. |
