What Is Opportunity Cost?
Opportunity costs represent the potential benefits an individual, investor, or business misses out on when choosing one alternative over another. The idea of opportunity costs is a major concept in economics.
Because by definition they are unseen, opportunity costs can be easily overlooked if one is not careful. Understanding the potential missed opportunities foregone by choosing one investment over another allows for better decision-making.
While financial reports do not show opportunity costs, business owners often use the concept to make educated decisions when they have multiple options before them. Bottlenecks, for instance, are often a result of opportunity costs.
- Opportunity cost is the forgone benefit that would have been derived by an option not chosen.
- To properly evaluate opportunity costs, the costs and benefits of every option available must be considered and weighed against the others.
- Considering the value of opportunity costs can guide individuals and organizations to more profitable decision-making.
Opportunity Cost Formula and Calculation
Opportunity Cost=FO−COwhere:FO=Return on best foregone option
The formula for calculating an opportunity cost is simply the difference between the expected returns of each option. Say that you have option A: to invest in the stock market hoping to generate capital gain returns. Option B, on the other hand is: to reinvest your money back into the business, expecting that newer equipment will increase production efficiency, leading to lower operational expenses and a higher profit margin.
Assume the expected return on investment in the stock market is 12 percent over the next year, and your company expects the equipment update to generate a 10 percent return over the same period. The opportunity cost of choosing the equipment over the stock market is (12% - 10%), which equals two percentage points. In other words, by investing in the business, you would forgo the opportunity to earn a higher return.
Opportunity Cost and Capital Structure
Opportunity cost analysis also plays a crucial role in determining a business's capital structure.
A firm incurs an expense in issuing both debt and equity capital to compensate lenders and shareholders for the risk of investment, yet each also carries an opportunity cost. Funds used to make payments on loans, for example, cannot be invested in stocks or bonds, which offer the potential for investment income. The company must decide if the expansion made by the leveraging power of debt will generate greater profits than it could make through investments. A firm tries to weight the costs and benefits of issuing debt and stock, including both monetary and non-monetary considerations, in order to arrive at an optimal balance that minimizes opportunity costs. Because opportunity cost is a forward-looking consideration, the actual rate of return for both options is unknown today, making this evaluation in practice tricky.
Assume the company in the above example foregoes new equipment and instead invests in the stock market. If the selected securities decrease in value, the company could end up losing money rather than enjoying the expected 12 percent return.
For the sake of simplicity, assume the investment yields a return of 0%, meaning the company gets out exactly what it put in. The opportunity cost of choosing this option is 10% - 0%, or 10%. It is equally possible that, had the company chosen new equipment, there would be no effect on production efficiency, and profits would remain stable. The opportunity cost of choosing this option is then 12% rather than the expected 2%.
It is important to compare investment options that have a similar risk. Comparing a Treasury bill, which is virtually risk-free, to investment in a highly volatile stock can cause a misleading calculation. Both options may have expected returns of 5%, but the U.S. Government backs the rate of return of the T-bill, while there is no such guarantee in the stock market. While the opportunity cost of either option is 0 percent, the T-bill is the safer bet when you consider the relative risk of each investment.
When assessing the potential profitability of various investments, businesses look for the option that is likely to yield the greatest return. Often, they can determine this by looking at the expected rate of return for an investment vehicle. However, businesses must also consider the opportunity cost of each option.
Assume that, given a set amount of money for investment, a business must choose between investing funds in securities or using it to purchase new equipment. No matter which option the business chooses, the potential profit it gives up by not investing in the other option is the opportunity cost. Indeed, it is unavoidable.
Opportunity Cost vs. Sunk Cost
The difference between an opportunity cost and a sunk cost is the difference between money already spent in the past and potential returns not earned in the future on an investment because the capital was invested elsewhere. Buying 1,000 shares of company A at $10 a share, for instance, represents a sunk cost of $10,000. This is the amount of money paid out to make an investment, and getting that money back requires liquidating stock at or above the purchase price. But the opportunity cost instead asks where could have that $10,000 been put to use in a better way.
From an accounting perspective, a sunk cost could also refer to the initial outlay to purchase an expensive piece of heavy equipment, which might be amortized over time, but which is sunk in the sense that you won't be getting it back. An opportunity cost would be to consider the forgone returns possibly earned elsewhere when you buy a piece of heavy equipment with an expected return on investment (ROI) of 5% vs. one with an ROI of 4%.
Again, an opportunity cost describes the returns that one could have earned if he or she invested the money in another instrument. Thus, while 1,000 shares in company A might eventually sell for $12 a share, netting a profit of $2,000, during the same period, company B increased in value from $10 a share to $15. In this scenario, investing $10,000 in company A returned $2,000, while the same amount invested in company B would have returned a larger $5,000. The $3,000 difference is the opportunity cost of choosing company A over company B.
As an investor that has already sunk money into investments, you might find another investment that promises greater returns. The opportunity cost of holding the underperforming asset may rise to where the rational investment option is to sell and invest in the more promising investment.
Risk vs. Opportunity Cost
In economics, risk describes the possibility that an investment's actual and projected returns are different and that the investor loses some or all of the principal. Opportunity cost concerns the possibility that the returns of a chosen investment are lower than the returns of a forgone investment. The key difference is that risk compares the actual performance of an investment against the projected performance of the same investment, while opportunity cost compares the actual performance of an investment against the actual performance of a different investment.
Still, one could consider opportunity costs when deciding between two risk profiles. If investment A is risky but has an ROI of 25% while investment B is far less risky but only has an ROI of 5%, even though investment A may succeed, it may not. And if it fails, then the opportunity cost of going with option B will be salient.
Example of Opportunity Cost
When making big decisions like buying a home or starting a business, you will probably scrupulously research the pros and cons of your financial decision, but most day-to-day choices aren't made with a full understanding of the potential opportunity costs. If they're cautious about a purchase, many people just look at their savings account and check their balance before spending money. Often, people don't think about the things they must give up when they make those decisions.
The problem comes up when you never look at what else you could do with your money or buy things without considering the lost opportunities. Having takeout for lunch occasionally can be a wise decision, especially if it gets you out of the office for a much-needed break.
However, buying one cheeseburger every day for the next 25 years could lead to several missed opportunities. Aside from the missed opportunity for better health, spending that $4.50 on a burger could add up to just over $52,000 in that time frame, assuming a very achievable 5% rate of return.
This is a simple example, but the core message holds true for a variety of situations. It may sound like overkill to think about opportunity costs every time you want to buy a candy bar or go on vacation. Even clipping coupons versus going to the supermarket empty-handed is an example of an opportunity cost unless the time used to clip coupons is better spent working in a more profitable venture than the savings promised by the coupons. Opportunity costs are everywhere and occur with every decision made, big or small.
Frequently Asked Questions
What is a simple definition of opportunity cost?
Opportunity cost is a very important concept in economics, but it is often overlooked by investors. In essence, it refers to the hidden cost associated with not taking an alternative course of action. If, for example, a company pursues a particular business strategy without first considering the merits of alternative strategies available to them, they might therefore fail to appreciate their opportunity costs. Although the company’s chosen strategy might turn out to be the best one available, it is also possible that they could have done even better had they chosen another path.
Is opportunity cost a real cost?
Some would argue that opportunity cost is not a “real” cost because it does not show up directly on a company’s financial statements. But economically speaking, opportunity costs are still very real. Nevertheless, because opportunity cost is a relatively abstract concept, many companies, executives, and investors fail to account for it in their everyday decision-making. In the long run, however, opportunity costs can have a very substantial effect on the outcomes achieved by individuals or companies.
What is an example of opportunity cost?
Consider the case of an investor who, at the age of 18, was encouraged by their parents to always put 100% of their disposable income into bonds. Over the next 50 years, this investor dutifully invested $5,000 per year in bonds, achieving an average annual return of 2.50% and retiring with a portfolio worth nearly $500,000. Although this result might seem impressive, it is less so when one considers the investor’s opportunity cost. If, for example, they had instead invested half of their money in the stock market and received an average blended return of 5.00%, then their retirement portfolio would have been worth over $1 million.
