Difference between Relevant Costs and Irrelevant Costs

In order to exercise cost control, managers must be able to make distinction between relevant costs and irrelevant costs. Costs that are affected by the managerial decisions are known as relevant costs and those costs that are not affected are treated as irrelevant costs. Irrelevant costs are not affected by the managerial decisions and hence are ignored while taking decisions.

E.) After analyzing the relevant costs, the company will have a net annual savings of $18,000. The company will be able to decrease its variable costs by $28,000 but will incur in incremental costs of $10,000 due to increase in depreciation. The relevant costs are incurred mainly by the lower management, whereas the irrelevant costs are mainly incurred by top management. Relevant costs are usually variable in nature, while irrelevant costs are usually fixed in nature.

1 Characteristics of Irrelevant Costs

The relevant costs are focused on daily or routine activities, whereas the irrelevant costs are focused on non-routine activities. The relevant costs are mainly related to the operational or recurring expenditures, whereas the irrelevant costs are mainly related to the capital or one-off expenditures. In context of business decisions, the relevancy of a cost depends on its nature in a particular situation. In above example of CPT Inc., the list of costs has been classified on the basis of this concept. The classification of costs as relevant and irrelevant is of great importance in cost and profitability analysis, especially when management has to choose between alternatives. For taking the sound managerial decisions, non-cost factors (i.e., qualitative considerations) should also be taken into consideration in addition to cost factors.

2 Make-or-Buy Decision

• (3) Rs.35,000 paid as salary to two members of the supervisory staff who can replace other positions is the relevant cost for the contract.
• A manufacturing firm has a factory lease of $10,000 per month, which remains constant regardless of production levels.
• Irrelevant costs are often sunk costs, which are expenses that have already been incurred and cannot be recovered.
• It’s important to note that just because a cost is irrelevant does not mean it is insignificant.
• However, when making decisions, it’s essential to focus on the relevant costs, as these are the costs that will actually impact the decision.

Costs that stay the same, regardless of which alternative is chosen, are irrelevant to the decision being made. Historical costs are irrelevant to the decision even though they may be the best available basis for predicting relevant costs. Irrelevant costs, on the other hand, are constant and do not change based on the decision being made. Identify which fixed costs remain constant and which may change based on the decision, ensuring proper classification. Relevant costs help in determining the break-even point and understanding how changes in production levels affect profitability. C.) The variable costs are relevant since the total variable cost will be different if the company chooses to buy the complementary machine.

Relevant vs Irrelevant Costs

Only the costs, which can be avoided if a particular decision is not implemented, are relevant for decision making. The Professional Scrum Product Owner™ II (PSPO II) certification validates your understanding of advanced Professional Scrum Product Ownership, the Scrum framework and delivering valuable products. Dummies has always stood for taking on complex concepts and making them easy to understand. Dummies helps everyone be more knowledgeable and confident in applying what they know. It can only be used on another product, the material for which is available at Rs.1, 35,000 (Material X requires some adaptation to be used and costs Rs.27,000). Keeping in view points (ii) and (iii), the items should be sold through normal distribution channels which will involve a differential cost of Rs.2 (i.e. Rs.3 – Rs.1) per unit.

Examples of irrelevant costs:

For example, imagine a company is deciding whether to continue producing a product or discontinue it. The cost of the machinery used in the production process is an irrelevant cost because it has already been purchased and cannot be recovered. Whether the company continues production or not, the cost of the machinery remains the same, making it irrelevant to the decision. Finally, relevant costs are also significant in determining the optimal production level. This helps to minimize the impact of sunk costs, which are costs that have already been incurred and cannot be recovered, and to focus on the future costs that will be incurred. Relevant costs also include the costs of materials, direct labor, and overhead expenses.

We have already discussed different categories of costs in current chapter – classification of costs. In this article, we would talk about relevant and irrelevant costs – another classification which is based on whether or not a cost can be controlled or affected through managerial decisions. By understanding these key differences, businesses can effectively distinguish between relevant and irrelevant costs.

• Costs that stay the same, regardless of which alternative is chosen, are irrelevant to the decision being made.
• For instance, consider a company deciding whether to make a product in-house or outsource it.
• When making business decisions, non-cash expenses should be excluded from the analysis, as they do not affect the immediate financial position or liquidity of the company.
• In this article, we would talk about relevant and irrelevant costs – another classification which is based on whether or not a cost can be controlled or affected through managerial decisions.
• In commercial entities, the cost accounting is a prominent aspect for internal control and decision making.

On the other hand, the irrelevant costs are general or absorbed fixed costs, committed costs, sunk costs etc. Another common misunderstanding is the assumption that irrelevant costs are always easy to identify. In reality, distinguishing between relevant and irrelevant costs can be complex, especially in large organizations with intricate financial structures. Costs that appear irrelevant at first glance may have indirect implications that affect the decision at hand.

Understanding the difference between relevant and irrelevant costs can help companies make better-informed business decisions. Cost analysis is a crucial aspect of decision-making in business, helping managers allocate resources effectively and maximize profitability. Among the various cost classifications, relevant and irrelevant costs play a significant role in determining the financial impact of different courses of action. In essence, distinguishing between relevant and irrelevant costs empowers businesses to make informed choices that maximize profitability, minimize biases, and optimize resource allocation. This is the cornerstone of effective financial management and strategic decision-making.

Examples of Irrelevant Costs

For example, if a company decides to replace an outdated piece of equipment, the original cost of the equipment is irrelevant. The only relevant cost is the cost of the new equipment and the cost of disposing of the old equipment. Clearly outline the decision to be made, including all potential alternatives, to identify costs that vary between options. Non-cash expenses like depreciation are not relevant as they do not affect the cash flows of a firm. Relevant costs are affected by a managerial choice in a certain business situation. In other words, these are the costs which shall be incurred in one managerial alternative and avoided in another.

Usually, most variable costs are relevant as they vary depending on selected alternative. Fixed costs are thought to be irrelevant assuming that the decision does not involve doing anything that would change these fixed costs. But, a decision alternative being considered might involve a change in fixed costs, e.g. a bigger factory shade.

This distinction allows for a clearer picture of the financial implications of each option, ultimately leading to better decision-making. An irrelevant cost, on the other hand, is an expense that will not change regardless of the decision being made. These costs have already been incurred or are predetermined, and they will not be affected by choosing one alternative over another. Irrelevant costs can cloud the decision-making process if they are not properly identified and excluded from the analysis.

The defining characteristic of relevant costs is that they are future costs that will differ among decision alternatives. Irrelevant costs do not have any bearing when choosing over different alternatives. Irrelevant costs are costs, either positive or negative, that would not be affected by a management decision. Irrelevant costs, such as fixed overhead and sunk costs, are therefore ignored when that decision is made. However, it’s critical for a manager to be able to distinguish an irrelevant cost in order to potentially save the business. Generally speaking, most variable costs are relevant because they depend on which alternative is selected.

Cash expense, which will be incurred in future because of a decision, is a relevant cost. It can be noted that fixed costs are often irrelevant because they cannot be altered in any given situation. relevant and irrelevant cost Any cost, fixed or variable that would be different for a particular course of action being analyzed is relevant for that alternative.

Exclude sunk costs from decision-making processes, focusing only on future costs and benefits. A company spends $50,000 on research for a product, but later decides to pivot. The $50,000 is a sunk cost and irrelevant for future decisions about whether to proceed with the project. While relevant costs are useful in short-term; but for the long-term, price should provide a sufficient profit margin above the total cost and not just the relevant costs. Most costs which are irrelevant in the short term become avoidable and relevant in the long term.
