A relevant cost (also called avoidable cost or differential cost)[1] is a cost that differs between alternatives being considered.[2] In order for a cost to be a relevant cost it must be:
Future
Cash Flow
Incremental
It is often important for businesses to distinguish between relevant and irrelevant costs when analyzing alternatives because erroneously considering irrelevant costs can lead to unsound business decisions.[1] Also, ignoring irrelevant data in analysis can save time and effort.
Types of irrelevant costs are:[3]
Sunk costs[4]
Committed costs
Notional or Non cash costs (e.g depreciation and amortization)
