However, the same cost may be relevant to a different management decision. Consequently, it is important to formally define and document those costs that should be excluded from consideration when reaching a decision. Because an irrelevant cost may be a relevant cost in a different management decision, it is important to formally define and document costs that should be excluded from consideration when reaching a decision. The sunk cost does not affect the future decisions of the company. Now, check your understanding of sunk costs and other irrelevant information. For example, suppose the B&B owner also had an option to convert the spare room into either a room with a bath or a room without a bath (that would use a shared bath upstairs).
Classifying costs as either irrelevant or relevant is useful for managers making decisions about the profitability of different alternatives. Costs that stay the same, regardless of which alternative is chosen, are irrelevant to the decision being made. The sunk costs are the costs which have already incurred such as investment made in… The correct answer to the given question is option b) sunk costs. Future costs that do not differ between alternatives are irrelevant and may be ignored since they affect both alternatives similarly. The company presently operates the machine for a single eight-hour shift for 22 working days each month.
Module 8: Short-term Decision Making
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. Identify some qualitative factors that should be considered when making managerial decisions. It can be noted that fixed costs are often irrelevant because they cannot be altered in any given situation.
- The sunk costs are the costs which have already incurred such as investment made in…
- Fixed overhead and sunk costs are examples of irrelevant costs that would not affect the decision to shut down a division of a company, or make a product instead of purchasing it from a supplier.
- Irrelevant costs, such as fixed overhead and sunk costs, are therefore ignored when that decision is made.
- It can be noted that fixed costs are often irrelevant because they cannot be altered in any given situation.
Of course, if rooms with a bath cost more to keep up than rooms without, the housekeeping variable cost becomes relevant again. The Decision-making process differs among various organizations. Learn the intelligence, design, and choice stages in the process, and the different types of decisions they lead to which help facilitate countless areas in personal, and professional life. A dealer has told you the trade-in value of your old car will be $200. The newer used car will require you to make monthly payments of $250 for two years.

Sunk costs, such as the purchased cost of a fixed asset that was incurred in a prior period, are also usually considered irrelevant when making decisions on a go-forward basis. Committed costs are also usually considered irrelevant, since these are future costs for which the firm has made a firm commitment that cannot be abrogated. Colt Company owns a machine that can produce two specialized products. Production time for Product TLX is two units per hour and for Product MTV is five units per hour. Both products are sold to a single customer who has agreed to buy all of the company’s output up to a maximum of 4,700 units of Product TLX and 2,500 units of Product MTV.
Selling prices and variable costs per unit to produce the products follow. Determine (1) the company’s most profitable sales mix and (2) the contribution margin that results from that sales mix. 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.
Operational 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. The concept seems simple enough, but including sunk costs in the decision-making process can be tempting. Your alternatives are to (a) get the repairs completed or (b) trade in the car for a newer used car.
Likewise, the wages of employees retained after the sale of a division would be irrelevant to the decision to sell it. 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. Non-cash items, such as depreciation and amortization, are frequently categorized as irrelevant costs for most types of management decisions, since they do not impact cash flows.
Step 1: Definition of Sunk Cost
The costs incurred by a firm may be categorized into different buckets depending upon the application. Some examples of such costs could be fixed costs and variable costs, avoidable and unavoidable costs, relevant and irrelevant costs, opportunity costs, sunk costs, incremental and non-incremental costs etc. Fixed overhead and sunk costs are examples of irrelevant costs that would not affect the decision to shut down a division of a company, or make a product instead of purchasing it from a supplier. For example, if a company bought a machine that broke and could not be returned, this sunk cost would be irrelevant to the decision to replace the machine or get a supplier to do the manufacturing.
Irrelevant Cost in Business: Meaning and Examples
A relevant cost is any cost that will be different among various alternatives. There is seldom a “one-size fits all” situation for relevant or irrelevant costs. The book value of fixed assets like machinery, equipment, and inventory is another example of irrelevant sunk costs. The book value of a machine is a sunk cost that does not affect a decision involving its replacement. For example, the salary of an investor relations officer may be an irrelevant cost if a management decision relates to issuing a new product, since dealing with investors has nothing to do with that particular decision. However, if the board of directors is considering taking the company private, then it may no longer need an investor relations officer; in the latter case, this person’s salary is highly relevant to the decision.
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. Past costs, also known as sunk costs, are not relevant in decision making because they have already been incurred; therefore, these costs cannot be changed no matter which alternative is selected. The sunk cost is irrelevant to deciding whether to sell a product in its present condition or make it into a new product because it has already occurred, and no current amount of the sunk cost remains.
Step 2: Sunk cost is irrelevant while making future decisions-
The point of not including sunk costs is that they are not going to change or be avoidable. Under either scenario, the $2,100 spent on the car and repairs prior to this decision-point are the same. An irrelevant cost is a cost that will not change as the result of a management decision.
