In managerial accounting, the concept of relevant costs plays a crucial role in decision-making by focusing on costs that are directly affected by specific management choices. Conversely, irrelevant costs are those that remain unaffected by such decisions. Fixed costs, often considered a significant expense for businesses, fall under scrutiny when determining their relevance in decision-making.
Key Facts
- Relevant costs are costs that will be affected by a managerial decision, while irrelevant costs are costs that won’t be affected by a managerial decision.
- Fixed costs can be relevant if they are related to a specific decision. However, fixed costs that are general in nature and incurred regardless of the decision are considered irrelevant.
- Fixed overhead and sunk costs are examples of irrelevant costs that would not affect certain decisions, such as shutting down a division or making a product instead of purchasing it.
- Relevant costs are differential costs that differ among different alternatives, while irrelevant costs stay the same regardless of the alternative chosen.
- Examples of relevant costs include future cash flows, avoidable costs, opportunity costs, and incremental costs.
- The concept of relevant cost is used in managerial accounting to eliminate unnecessary data and simplify the decision-making process.
- Sunk costs, which have already been incurred regardless of the decision, are the opposite of relevant costs.
Understanding Relevant and Irrelevant Costs
Relevant costs are those that change in response to a managerial decision. They are incremental costs that differ among various alternatives, allowing decision-makers to assess the true cost difference and make informed choices. On the other hand, irrelevant costs are those that remain constant regardless of the decision made. They do not provide valuable insights for decision-making since they will not be affected by the chosen alternative.
Fixed Costs: Relevant or Irrelevant?
Fixed costs are expenses that remain constant over a specific period, regardless of the level of activity. Examples include rent, depreciation, and salaries of administrative staff. Traditionally, fixed costs are considered irrelevant in decision-making because they are not directly affected by the decision. However, this notion is not entirely accurate.
Fixed costs can be relevant in certain decision-making scenarios, particularly when they are specific to the decision being made. For instance, if a company is considering shutting down a particular division, the fixed costs associated with that division, such as rent and salaries of employees who will be laid off, become relevant. These costs can be avoided if the division is closed, making them relevant to the decision.
General Fixed Costs vs. Specific Fixed Costs
The key distinction lies in the specificity of fixed costs to the decision being made. General fixed costs, such as rent for the company’s headquarters, are typically irrelevant because they will not change regardless of the decision. However, specific fixed costs, such as rent for a factory that would be closed if a product line is discontinued, are relevant because they can be avoided by making a particular decision.
Conclusion
The relevance of fixed costs in decision-making depends on their specificity to the decision being considered. Fixed costs that are directly tied to the decision and can be avoided or incurred based on the chosen alternative are considered relevant costs. In contrast, general fixed costs that are not specific to the decision and will not be affected by it are considered irrelevant costs.

FAQs
What are relevant costs?
Relevant costs are costs that change in response to a managerial decision. They are incremental costs that differ among various alternatives, allowing decision-makers to assess the true cost difference and make informed choices.
What are irrelevant costs?
Irrelevant costs are those that remain constant regardless of the decision made. They do not provide valuable insights for decision-making since they will not be affected by the chosen alternative.
Are fixed costs always irrelevant?
No, fixed costs can be relevant in certain decision-making scenarios, particularly when they are specific to the decision being made. For instance, if a company is considering shutting down a particular division, the fixed costs associated with that division become relevant because they can be avoided by making that decision.
How can fixed costs be relevant?
Fixed costs can be relevant when they are specific to the decision being considered and can be avoided or incurred based on the chosen alternative. For example, rent for a factory that would be closed if a product line is discontinued is a relevant cost because it can be avoided by making that decision.
What are general fixed costs?
General fixed costs are those that are not specific to a particular decision and will not be affected by it. For example, rent for the company’s headquarters is a general fixed cost because it will not change regardless of the decision being made.
What are specific fixed costs?
Specific fixed costs are those that are directly tied to the decision being considered and can be avoided or incurred based on the chosen alternative. For example, rent for a factory that would be closed if a product line is discontinued is a specific fixed cost because it can be avoided by making that decision.
When are fixed costs irrelevant?
Fixed costs are irrelevant when they are general in nature and not specific to the decision being made. They are also irrelevant when they cannot be avoided or incurred based on the chosen alternative.
Why is it important to distinguish between relevant and irrelevant fixed costs?
Distinguishing between relevant and irrelevant fixed costs is important because it allows decision-makers to focus on the costs that are directly affected by the decision being made. This leads to more accurate and informed decision-making.
