Relevant Cost Definition, Types, Examples, Decision Making

relevant and irrelevant cost

These costs are often the result of past decisions and should not influence current or future business choices. For instance, if a company has invested heavily in a piece of machinery that is now obsolete, the initial investment is a sunk cost. Continuing to factor this expense into new decisions can lead to poor judgment, as it does not affect the potential outcomes of future actions. Instead, decision-makers should focus on prospective costs and benefits, ensuring that past expenditures do not cloud their judgment. In the realm of financial decision-making, it is essential to recognize various types of irrelevant costs. These costs, while part of the overall financial landscape, do not influence the decisions at hand and should be excluded from the analysis.

Appropriate cost analysis form plays a primary role in making that decision. A company that deals with making finished goods requires specific parts. The company has to decide whether to make the parts internally or outsource. Direct materials, direct labor, and various overhead costs are examples of the make or buy situation. Irrelevant costs have to be incurred irrespective of a new decision. These are the costs that will be incurred in all the alternatives being considered.

If the additional revenue is greater than the additional cost, it is profitable to utilize the idle capacity. An irrelevant cost is a category of cost that is not affected by managerial decisions. This means this cost does not change regardless of changes in decisions made by the management. Irrelevant costs are used in managerial accounting to describe costs that are relevant to managerial decisions but do not change as a result of the decision made.

While evaluating two alternatives, the focus of analysis is on finding out which alternative is more profitable. 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.

Identifying Irrelevant Costs in Financial Statements

Some fixed costs can become relevant in specific contexts, such as when evaluating the long-term viability of a business unit or considering a significant strategic shift. Misunderstanding this nuance can lead to oversimplified analyses and suboptimal decisions. 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.

Irrelevant Costs vs. Relevant Costs

But, a decision alternative being considered might involve a change in fixed costs, e.g. a bigger factory shade. In the long term, both relevant and irrelevant costs become relevant and irrelevant cost variable costs. 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. These costs are relevant because they will only occur if the decision to expand is implemented.

For instance, purchasing advertising services from a marketing firm will increase advertising expenses but should bring in more sales to the company. When making this decision, you need to make sure that you’re maximizing every dollar invested and getting a high return. In this scenario, there is no opportunity cost to accept the special order since we can produce the order without lowering other production.

Role of Relevant Costs in Short-Term Decisions

  1. The concept of relevant cost is used to eliminate unnecessary data that could complicate the decision-making process.
  2. This would allow production to be increased because the machine has to deal with only Operation 2.
  3. Material – if the buy-in option is accepted, the material cost increases from $12 to $15 per unit.
  4. If the product cost price is below production cost, the company can safely decide to take special orders.
  5. The closure of Production Line A would also result in the revenue lost being greater than the value of the costs saved, so this isn’t a good idea either.

These costs help in establishing a baseline price that ensures profitability. 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. A relevant cost for decision-making is a cost that varies when evaluating two or more alternatives. Relevant costing is used only for short-term and nonroutine decisions.

Impact of Irrelevant Costs on Decision Making

If a client wants a price quote for a special order, management only considers the variable costs to produce the goods, specifically material and labor costs. Fixed costs, such as a factory lease or manager salaries, are irrelevant because the firm has already paid for those costs with prior sales. Below, we provide the common relevant costing decisions and examples that you might encounter in your small business. We also show the computations on how the decision will affect your margins and financial performance. In general, most variable costs are relevant while most fixed costs are irrelevant. This general rule holds true most of the time since variable costs behave differently across activity levels while fixed costs remain constant nonetheless.

Since we are at full capacity, we will be unable to sell 200 units to normal customers. Hence, we will lose a $7.5 ($29 – $۵٫۲۵ – $۸٫۷۵ – $۷٫۵۰) CM per unit. A special order decision arises when customers request to buy a special product that’s not part of the normal product line. For example, the famous chocolate candy brand M&M’s offers “party favors” to customers who want personalized M&M candies with their names printed on them. This type of order can be a special order since it’s not part of M&M’s regular product line.
