Irrelevant costs are costs which are independent of the various decisions or alternatives. For example, in case of idle capacity utilization; additional costs that will be incurred for utilizing idle capacity are relevant costs. Additional costs are compared with the additional revenue from utilizing idle capacity. https://1investing.in/ If the additional revenue is greater than the additional cost, it is profitable to utilize the idle capacity. As another example, the rent for a production building is irrelevant to the decision to automate a production line, as long as the automated equipment is still housed within the same facility.
To summarize relevant costs and irrelevant costs in accounting, we learned that determining these costs depends on the situation. Differential, avoidable, and opportunity costs are considered relevant costs. Using examples to demonstrate these costs show us that which costs are included in what places depend on what decision is made and the specific situation. Various types of relevant costs are variable or marginal costs, incremental costs, specific costs, avoidable fixed costs, opportunity costs, etc. The irrelevant costs are fixed costs, sunk costs, overhead costs, committed costs, historical costs, etc. Depreciation expenses and taxes are also considered irrelevant costs, as current decisions cannot alter them.
- Both relevant costs and irrelevant costs are required to provide estimates of average cost of production or service offering of an organization or business.
- These cost concepts play a crucial role in decision-making but in different ways.
- In other words, irrelevant costs do not change with the different options being considered.
Unavoidable costs are those that the company will incur regardless of the decision it makes, e.g. committed fixed costs like depreciation on existing plant. 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.
Making Decisions using Relevant and Irrelevant Costs – A Business Case:
Avoidable costs are those costs that are avoided by choosing to eliminate the home design branch versus keeping it. If we choose to eliminate the division, we will no longer have the costs of the employees’ salaries, trucks to move materials, and licenses for home design software. The opposite of a relevant cost is a sunk cost, which has already been incurred regardless of the outcome of the current decision. C.) The variable costs are relevant since the total variable cost will be different if the company chooses to buy the complementary machine. Irrelevant costs have to be incurred irrespective of a new decision. Another helpful tool when determining relevant cost involves looking at opportunity cost — what must you give up if you choose one option over another?
Finally, relevant costs are also significant in determining the optimal production level. In addition, relevant costs are also valuable for determining the cost of production. This is because they take into account only the costs directly related to the production process rather than the total costs incurred in the production process. Opportunity costs are the revenues that are lost by choosing to keep the home design branch versus eliminating it.
In other words, relevant costs are those costs that experience some change, whether negative or positive, because of a decision that management makes. 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. As the name suggests they are ‘relevant’ for managerial analysis and should be considered in all calculations made for the purpose. The relevant costs may be avoided, whereas the irrelevant costs are usually unavoidable. The relevant costs are incurred mainly by the lower management, whereas the irrelevant costs are mainly incurred by top management.
What Are the Similarities Between Relevant Cost and Irrelevant Cost?
Committed costs are costs that would be incurred in the future but they cannot be avoided because the company has already committed to them through another decision which has been made. Irrelevant costs, on the other hand, are constant and do not change based on the decision being made. There are several different relevant costs that a business must consider. Each type of cost provides information that must be taken into account.
Irrelevant Costs vs. Relevant Costs
Another example could be when deciding whether to outsource production overseas or keep it in-house. Relevant costs would include things like labor costs and shipping expenses for outsourcing versus salary expenses and equipment maintenance for keeping production in-house. Operation 1 takes 0.25 hours of machine time and Operation 2 takes 0.5 hours of machine time.
General and administrative overheads, that are not affected by the alternative decisions, are not relevant. Only Rs. 1,25,000 would be avoidable, if the contract is not accepted. (iii) Skilled labour can work on other contracts which are presently operated by semi-skilled labour at a cost of Rs.5,70,000. Identifying these unnecessary expenditures can help businesses make informed decisions without getting sidetracked by trivial details. Production volume – this can increase by 50% because currently each item takes 0.5 hours in Operation 2, but 0.25 hours per unit will be released by Operation 1 which now will not be needed.
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. In the following sections, we will look at relevant and irrelevant costs in more detail, including examples of each cost type and how they are used in decision-making. We know that management is thinking about purchasing sewing machines and laying off two seamstresses. Currently, you have five employees who sew the dolls together buy hand, carefully stitching every detail. As your business continues to grow, you begin to think about the possibility of purchasing sewing machines that would significantly speed up the process of doll-making.
An irrelevant cost is an expense that a business can not avoid paying. A big decision for a manager is whether to close a business unit or continue to operate it, and relevant costs are the basis for the decision. Assume, for example, a chain of retail sporting goods stores is considering closing a group of stores catering to the outdoor sports market. The relevant costs are the costs that can be eliminated due to the closure, as well as the revenue lost when the stores are closed. If the costs to be eliminated are greater than the revenue lost, the outdoor stores should be closed.
Continue Operating vs. Closing Business Units
The company is contemplating on buying an additional machine worth $80,000, to be used in conjunction with the old. Though units produced will stay the same, the company expects a significant decrease in variable costs from $68,000 to $40,000, annually. The relevant costs are usually related to a particular division or section, whereas the irrelevant costs are usually related to organization wide activities. The relevant costs are usually related to the short term, while the irrelevant costs are usually related to the long term. Understanding what constitutes relevant costs is crucial for making informed decisions that align with your goals. Say, for example, that 4 hours of labour were simply removed by ‘sacking’ an employee for four hours, one less unit of Product X could be made.
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. 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.

Relevant costs are where a company should focus most of its attention because these expenses can be adjusted when necessary. However, irrelevant costs can not be changed, and mistaking an irrelevant difference between relevant and irrelevant cost cost will wrongly inflate relevant costs. It is a sound business practice to reduce relevant costs as much as possible because they can be adjusted to produce financial benefits.
