How is relevant costing used in decision making?

Relevant costing is utilized in decision-making to focus on costs that will directly impact a specific decision, such as incremental costs and revenues, while ignoring sunk costs and fixed costs that will not change. This approach helps businesses evaluate alternatives by highlighting the financial implications of each option. For instance, when deciding whether to accept a special order, companies can analyze the additional costs and potential revenues associated with that order to determine profitability. Ultimately, relevant costing aids in making informed choices that enhance financial performance.
