In the realm of business and finance, decision-making is a crucial aspect that impacts the success and profitability of an organization. To make informed decisions, it is essential to consider relevant costs and factors that can influence the outcome. Among the various types of costs, sunk costs stand out as a unique category that holds no relevance in decision-making processes. This article delves into the concept of sunk costs, their characteristics, and why they are deemed irrelevant in business decisions.
Key Facts
- Definition of Sunk Costs: Sunk costs are costs that have already been incurred and cannot be recovered. They are irrelevant to decision-making because they will remain the same regardless of the outcome of a decision.
- Examples of Sunk Costs: Some examples of sunk costs include money spent on research and development, marketing studies, nonrefundable deposits, salaries, rent, or repairs that cannot be recovered[3].

Understanding Sunk Costs
Sunk costs, as defined by Investopedia, are costs that have already been incurred and cannot be recovered. They are considered a subset of fixed costs and represent expenditures that have been made in the past and cannot be reversed or altered. Examples of sunk costs include money spent on research and development, marketing studies, nonrefundable deposits, salaries, rent, or repairs that cannot be recovered.
Irrelevance of Sunk Costs in Decision-Making
The primary reason why sunk costs are irrelevant in decision-making is that they are considered historical costs that cannot be changed or influenced by future actions. Regardless of the decision made, sunk costs will remain the same and will not affect the outcome. Therefore, including sunk costs in decision-making can lead to biased and inaccurate evaluations.
Key Points Regarding the Irrelevance of Sunk Costs:
- Sunk costs are not relevant because they cannot be changed or influenced by future decisions.
