Relevant Cost vs. Irrelevant Cost: What's the Difference?
"Relevant Cost" affects decision-making due to future outcomes, while "Irrelevant Cost" doesn't impact future decisions or outcomes.
"Relevant Cost" refers to the expenses directly linked to a specific business decision. These are costs that will differ based on the outcome of the decision in question. On the other hand, "Irrelevant Cost" doesn't change regardless of the decision made, having no bearing on future operations.
Understanding "Relevant Cost" is essential for effective decision-making in business. This cost influences the outcome of a business choice. For instance, if a company is determining whether to manufacture a product or outsource it, the varying costs associated with each option are the "Relevant Costs". Conversely, "Irrelevant Cost" plays no role in such determinations. Past incurred costs, often referred to as sunk costs, usually fall into this category.
It's crucial to identify "Relevant Cost" for budgeting and forecasting. These costs provide insights into how resources will be used in the future based on certain decisions. "Irrelevant Cost", on the contrary, should be set aside during decision-making processes. Including them can skew analysis and lead to inaccurate conclusions.
Lastly, in managerial accounting, discerning between "Relevant Cost" and "Irrelevant Cost" optimizes resource allocation. Making choices based on "Relevant Cost" ensures that funds are used efficiently. Ignoring "Irrelevant Cost" in the decision-making matrix prevents wastage of time and avoids confusion.
