Relevant cost is expected future cost Relevant cost is expected future cost which differs for alternative course. which differs for alternative course. Usually variable costs are relevant Usually variable costs are relevant while fixed cost are non-relevant. while fixed cost are non-relevant.

However, It is not essential that all However, It is not essential that all variable cost are relevant and all variable cost are relevant and all fixed cost are irrelevant. Fixed or fixed cost are irrelevant. Fixed or variable costs that differ for various variable costs that differ for various alternatives are relevant costs. alternatives are relevant costs.

Relevant costs draw our alternation Relevant costs draw our alternation to those elements of cost which are to those elements of cost which are relevant for decision.relevant for decision.e.g. 1)e.g. 1) Fixed Cost for project X is Rs. Fixed Cost for project X is Rs. 5 lakhs and for alternative project Y 5 lakhs and for alternative project Y it is 7 lakhs.it is 7 lakhs.therefore fixed cost is relevant in therefore fixed cost is relevant in this example. this example.

SUNK COSTS
Sunk costs are all costs incurred or committed in the past that cannot be changed by any decision made now or in the future. Sunk costs should not be considered in decisions.

SUNK COSTS
E.g. cost incurred on research of a product will be irrelevant while making decision whether to undertake production or not.

If selling price is above the variable If selling price is above the variable cost then it better to continue cost then it better to continue because the losses are minimized. because the losses are minimized. By closing the manufacturing By closing the manufacturing activity, some extra fixed expenses activity, some extra fixed expenses (e.g. Security) may be incurred and (e.g. Security) may be incurred and certain fixed expenses can be certain fixed expenses can be avoided (e.g. maintenance cost of avoided (e.g. maintenance cost of plant).
