Sunk Cost vs Relevant Cost: Understanding the Differences and Importance

Have you ever made a financial decision based on previous expenses, without considering the future impact? If so, you have fallen prey to the concept of sunk cost.

Many individuals and businesses suffer from this common mistake and end up losing money while hindering their growth. In this article, we will explore the differences between sunk cost and relevant cost, the importance of each concept, and why it is vital to consider all costs when making business decisions.

Sunk Cost: Definition and Example

A sunk cost refers to an expense that has already been incurred and cannot be recovered. In other words, no matter what decision you make, the expense will remain the same.

Therefore, it is an irrelevant cost when making future decisions. For example, suppose you spent $100 on a software program that you no longer use.

That $100 is considered a sunk cost because you cannot recover that money, regardless of the decision you make in the future.

Sunk Costs in Research and Development

Sunk costs are commonly encountered in research and development (R&D) projects. Businesses that undertake R&D projects often incur massive expenses in the hope of discovering something novel or enhancing their current product/service.

However, some companies struggle to recognize that, at some point, the sunk cost of an R&D project becomes too high, and the future costs of the project start to outweigh the potential benefits. The worst-case scenario for R&D projects is those that continuously incur sunk costs with no sign of break-even or profit.

In such cases, businesses need to make tough decisions like abandoning the project, regardless of the money already invested, to protect themselves from accruing more sunk costs that won’t benefit them. Relevant Cost: Definition and Importance

Relevant costs, on the other hand, are future outflows of cash that impact management decisions.

Relevant costs are both avoidable and incremental. They are avoidable because they are contingent on the decision the business makes and whether or not to pursue a particular opportunity or course.

They are incremental because they are the additional costs that the business will incur if it chooses to pursue a specific course of action. The importance of relevant costs lies in their ability to influence future business activities.

By considering the value of relevant costs, businesses can gain insight into the financial and operational impact of their decisions. It allows businesses to avoid the costs associated with sunk costs and minimize future costs where possible.

Consideration of all Costs in Long-Term Decisions

Despite recognizing the difference between sunk cost and relevant cost, it is vital to consider all the costs when making long-term business decisions. This is especially crucial in pricing decisions, investment appraisals, expanding into new ventures and markets, and even selling off business units.

It isn’t enough to analyze the sunk and relevant costs alone because the total cost often provides a better understanding of the ramifications of your decision. For example, if you were to invest in a new project, you might be hesitant to do so because it incurs significant sunk costs.

But, by considering the relevant costs as well, you could reap the benefits of the project in the long run.

Differences Between Sunk Cost and Relevant Cost

The similarities between the two costs lie in their potential to reduce a firm’s income and profitability. Both sunk and relevant costs impact the business’s bottom line and can influence decision-making processes.

However, the key difference is that sunk costs are a thing of the past. Businesses cannot change the expense, while relevant costs are prospective, and they often depend on a business’s future actions.

Final Thoughts

The concept of sunk cost is a common mistake that many individuals and businesses make. It can significantly impact a company’s profitability and hinder future growth.

Relevant costs are equally important because they present an opportunity for businesses to make better financial decisions. By recognizing the difference between sunk cost and relevant cost and considering all costs, businesses can make informed decisions that will minimize additional costs and maximize profitability.

In conclusion, understanding the differences between sunk costs and relevant costs is crucial for making informed business decisions. While sunk costs are expenses already incurred, relevant costs are future outflows that impact management decisions.

It is important to consider all costs, including sunk and relevant costs, when making long-term business decisions. By doing so, businesses can avoid the costs associated with sunk costs and minimize future costs where possible.

Ultimately, understanding the value of both types of costs can lead to smarter financial decisions and profitable growth for businesses.
