Opportunity Cost Formula & Practical Examples for Exams
Opportunity cost is a fundamental concept in economics and business that helps individuals and organizations make optimal choices by evaluating what they must sacrifice when deciding between alternatives. When you make a decision, you forgo the potential benefits of other options. The value of the next best alternative that is not chosen is called the opportunity cost.
What Is Opportunity Cost?
Opportunity cost refers to the benefit lost from the option you did not select. It is not recorded in accounting profits or external financial reports, but it plays a crucial role in assessing and improving decision-making. Considering opportunity costs helps students, businesses, and investors select alternatives that offer the maximum potential benefit.
For example, if a manufacturer must choose between building a new plant in Location A or Location B, the opportunity cost is the potential gain lost from not choosing the best alternative site.
Formula for Calculating Opportunity Cost
Calculating opportunity cost involves comparing the expected returns of two options. The basic formula is:
| Formula | Description |
|---|---|
| Opportunity Cost = Return of Next Best Alternative – Return of Selected Option | Measures the value of the choice not taken. |
Suppose a business has two options: invest in the stock market or purchase new equipment. If the stock market is expected to yield 10% and the equipment is expected to yield 8%, choosing equipment means the opportunity cost is the 2% higher return not earned by investing in stocks.
Examples of Opportunity Cost
Opportunity cost appears in daily life and business. An often-cited example is a 2010 transaction where someone exchanged 10,000 bitcoins for two pizzas, worth about $41 at that time. If the bitcoins had been held, they would have grown to be worth hundreds of millions later—the opportunity cost was enormous.
In investments, if you consistently put money in low-yield bonds rather than a combination of bonds and stocks, the opportunity cost is the extra return you would have received from the more balanced or higher-risk portfolio.
Step-by-Step Approach to Analyzing Opportunity Cost
- List all possible choices for the decision.
- Estimate the expected return or benefit from each option.
- Identify the next best alternative to your chosen action.
- Subtract the return of your selected option from the return of the next best alternative.
By following these steps, you ensure a logical approach for weighing options in economic, accounting, or business scenarios.
Key Principles and Definitions
-
Opportunity Cost:
The value of the foregone alternative when a choice is made; the hidden cost of ignoring other possibilities.
-
Explicit Costs:
Direct, out-of-pocket payments, such as wages or rent.
-
Implicit Costs:
The opportunity costs of using the company's own resources.
-
Opportunity Cost vs. Sunk Cost:
Opportunity cost concerns future choices, while sunk costs are past expenses that cannot be recovered.
-
Opportunity Cost vs. Risk:
Risk involves uncertainty about future outcomes, but opportunity cost is about the value of an alternative that's not taken.
-
Accounting Profit vs. Economic Profit:
Accounting profit considers only explicit costs. Economic profit deducts both explicit and implicit (including opportunity) costs.
Table: Explicit vs. Implicit vs. Opportunity Cost
| Cost Type | Definition | Example |
|---|---|---|
| Explicit Cost | Direct payment for use of resources | Salaries paid to employees |
| Implicit Cost | Value of using self-owned resources | Owner’s time or own capital used |
| Opportunity Cost | Benefit from the next best alternative foregone | Lost potential interest from an investment not taken |
Application and Limitations
Opportunity cost guides better resource allocation decisions in business, investing, and personal finance. However, since it deals with unselected options, it often involves forecast and estimation. This makes opportunity cost subjective and dependent on best available information. It is not a direct accounting entry but offers strategic insight.
Practice Problem
Suppose you have ₹10,000. You can either buy shares in Company X (expected return 7%) or put it in a savings deposit (expected return 5%). What is the opportunity cost of investing in Company X?
Opportunity Cost = Return from next best alternative (5%) – Return from chosen option (7%) = -2%. Here, there is no positive opportunity cost since your chosen option has a higher expected return.
Further Learning and Vedantu Resources
Mastering opportunity cost offers strong analytical skills for economic, investment, and business choices. By applying its formula and approach, you will improve clarity in decision-making and understand the real value behind every choice you make.
FAQs on What Is Opportunity Cost? A Complete Guide for Commerce Students
1. What is opportunity cost in economics?
Opportunity cost in economics is the value of the next best alternative foregone when a choice is made. It measures what you give up in order to pursue the selected option, helping individuals and businesses make better decisions by considering all alternatives.
2. Which answer best defines opportunity cost?
Opportunity cost is defined as the benefit or value of the next best alternative that must be given up when a choice is made. This economic concept highlights that resources are limited and selecting one option means forgoing others with potential benefits.
3. What is opportunity cost in simple terms?
Simply put, opportunity cost is what you miss out on when you choose one thing over another. It’s the value of what you could have gained by picking the next best option instead.
4. What is opportunity cost and give an example?
Opportunity cost is the benefit lost by not choosing the next best alternative.
Example: If you spend ₹500 on a book instead of watching a movie, the opportunity cost is the enjoyment or experience you would have gained from the movie.
5. What is the opportunity cost formula?
The standard opportunity cost formula is:
Opportunity Cost = Return of Next Best Alternative – Return of Chosen Option
This formula helps in calculating the value forgone by not selecting the second-best option.
6. How does opportunity cost apply in business decision-making?
Opportunity cost guides businesses to compare returns from different options before making decisions.
For example:
- Investing profits in expanding a factory or launching a new product line
- Choosing between hiring new employees or upgrading equipment
7. What is the difference between opportunity cost and accounting cost?
Accounting cost includes only actual expenses paid out, such as wages and rent.
Opportunity cost covers the value of the next best alternative foregone, which is not usually recorded in financial statements.
Opportunity cost is an economic concept, while accounting cost is a financial measure.
8. Why is opportunity cost important for students and exam preparation?
Opportunity cost is vital for mastering economics and business studies exam concepts because:
- It appears frequently in board exams, case studies, and MCQs
- Helps improve logical thinking and problem-solving skills
- Aligns with CBSE, ISC, and CA Foundation curriculum
9. What is an example of opportunity cost in daily life?
Example: If you spend time studying for economics instead of spending the same time playing sports, your opportunity cost is the fun and exercise you would have had by playing sports.
10. How is opportunity cost different from sunk cost?
Opportunity cost is about future alternatives that are not chosen, while sunk cost refers to expenses that have already been incurred and cannot be recovered. Decision-making should focus on opportunity cost, not sunk costs, as the latter are irrelevant to future choices.
11. How do you solve opportunity cost problems step-by-step?
To solve opportunity cost problems:
- Identify all available alternative options
- Calculate or estimate each alternative’s return or benefit
- Select the next best foregone alternative
- Use the formula: Opportunity Cost = Return of Next Best Alternative – Return of Chosen Option
12. Is opportunity cost included in calculating accounting profit?
No, opportunity cost is not included in accounting profit. It is considered in economic profit calculations but not recorded as an explicit cost in formal accounting statements. Economic profit = Total Revenue – (Explicit Costs + Implicit/Opportunity Costs).
