Relevant and Irrelevant Costs

(iii) If the items are scrapped and someone is asked to take them on “as is where is” basis, the company would have to spend Rs.5,000 over 5,000 units i.e. She has held multiple finance and banking classes for business schools and communities. These costs are never being taken into consideration while making a decision. Relevant costs are those which are stated to be avoidable while a decision is implemented.

Examples of Irrelevant Costs

For example, a cost which is relevant in respect of a particular activity or decision may turn out to be irrelevant for another one. Hence, the exercise of identifying relevant and irrelevant costs needs to be done afresh every time a new decision or activity is considered. Relevant costs help to eradicate unnecessary data that can complicate a decision-making process.

Relevant Costs and Pricing Strategies

Exclude sunk costs from decision-making processes, focusing only on future costs and benefits. Understanding relevant costs enables businesses to allocate resources effectively, optimizing profitability and operational efficiency. Relevant costs are costs that are affected by a managerial decision in a particular business situation. In other words these are the costs which shall be incurred in one managerial alternative and avoided in another.

Committed Costs

We have already discussed different categories of costs in current chapter – classification of costs. The ability to ignore sunk and fixed costs that do not change with the decision allows for a more accurate assessment of the financial implications of short-term actions. This clarity is particularly important when resources are constrained and the opportunity cost of choosing one alternative over another is high. Managers must ensure that the most profitable use of the company’s resources is selected, based on an understanding of the costs that will be directly affected by their decisions. Incorporating irrelevant costs into budgeting can lead to significant distortions in financial planning and resource allocation. When these costs are included, they can inflate budget estimates, making it difficult to accurately forecast future financial needs.

#2 – Continue Production or Close Business Unit

relevant and irrelevant cost

These costs are relevant since these expenses change in the future due to the buying decision. The comparison includes an examination of the incremental costs that would be saved by outsourcing, alongside any new costs that outsourcing might introduce. These new costs could include transition expenses, such as training and integration, or costs related to quality control and communication with the external provider.

Are all future costs considered relevant?

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. ABC Company is currently using a machine it purchased for $50,000 two years ago.

An irrelevant cost remains the same throughout the decision-making process. For instance, consider a company deciding whether to make a product in-house or outsource it. The cost of raw materials is a relevant cost because it varies depending on the alternative chosen.

  • A difference is observed in the relevant cost per each alternative decision.
  • Explore the strategic use of relevant cost analysis to enhance financial decisions, from outsourcing to pricing, and improve business performance.
  • These costs, while necessary for the overall operation, do not fluctuate with business activities and should be treated as irrelevant in decisions that aim to optimize variable costs.
  • In other words these are the costs which shall be incurred in one managerial alternative and avoided in another.
  • B.) The depreciation of the new additional machine, $10,000, is relevant since the company will incur such cost only when it decides to buy the new machine.

In short, they are never considered when a decision is taken regarding a cost. Only the incremental or differential costs related to the different alternatives, are relevant costs. C.) The variable costs are relevant since the total variable cost will be different if the company chooses to buy the complementary machine.

#3 – Opportunity Costs

  • The company shall free some space that can be leased if it decides to outsource.
  • Incremental costs are often variable, but they can also include fixed costs if those fixed costs will change as a direct result of the decision.
  • This approach ensures that budgets reflect the true financial position of the company, enabling more effective planning and execution of business strategies.
  • For example, if a decision is to be taken whether idle capacity should be utilized or not.

The final piece of the puzzle is the use of relevant cost analysis in evaluating financial performance. This involves not just looking at the costs themselves but understanding their behavior in relation to changes in business activity. Variable costs are scrutinized to see how efficiently they are being managed, as reductions in these costs can lead to improved margins. Managers use this information to make strategic decisions about cost control, process improvement, and capacity management. The process of identifying relevant costs is a preliminary step in the decision-making framework.

Additionally, managers must consider the incremental costs of producing one more unit to determine if the pricing can be adjusted for volume discounts or premium pricing strategies. Incremental costs, also known as differential or marginal costs, are the additional costs incurred when a business decides to increase its activity level. These costs are relevant when a company is considering a decision that will change its output or operations. For example, if a business is evaluating whether to expand its production, the additional costs of materials, labor, and utilities for the increased production are incremental costs.

The profitability is judged by considering the revenues generated by and costs incurred. Some costs may remain the same; but some costs may vary between the alternatives. Proper classification of costs between relevant and irrelevant costs is useful in such situations. The main difference lies in their impact on future cash flows related to a specific business decision.

Therefore, its cost is relevant but the relevant cost is the residual value of Rs.1,35,000 which can be realized. Additional costs incurred will be compared with the additional revenue arising by utilizing idle capacity. General and administrative overheads, that are not affected by the alternative decisions, are not relevant. B.) The depreciation of the new additional machine, $10,000, is relevant since the company will incur such cost only when it decides to buy the new machine. For example, a person has to choose between vacationing and spending time with their family. In this context, opportunity cost is the cost of the holiday and visiting new places if the person decides to go on vacation rather than stay home.

Whether the company purchases the new equipment or not, it will still incur the $5,000 depreciation. Take note that the company has already paid for the old machine (a sunk cost) and will continue to use it. The difference in costs in choosing one alternative over another is known as differential cost. Incremental cost refers to the increase in cost when choosing an alternative.

Costs that are same for various alternatives are not considered e.g. fixed costs. Only those costs that are different for each alternative are the relevant costs and are considered in decision making e.g. variable costs. The future expenses that might occur due to a decision made in the present are called future cash flows. The current value is used to project future revenues to see if a decision will incur future costs. Here, we can price the expected ongoing-project revenues with the current value. Then, a discounted rate is formulated to arrive at discounted relevant and irrelevant cost cash flows.
