In: Accounting
PT corp makes 300 units of A per year. At this level, the cost per unit includes $360 in direct materials, $1,000 in direct labor, $240 in variable overhead, and $900 in fixed overhead. An outside supplier has offered to make all 300 units for $2,100 per unit. If PT accepts this offer, two thirds of the fixed overhead would persist, but would be defrayed by renting out the floor space for $83,000 per year.
What are the relevant costs (in total) for continuing to make this product?
Ans: Relevant Costs- Relevant costs are the costs that is relevant to a decision making and by making such decision, there is a change in cash flow. They differs between alternatives. Costs that can be avoided are relevant costs.
In this question, PT Corp makes 300 units of A per year for which it incurs $360 for direct materials, $1000 for direct labor and $240 for variable overhead. It also incurs $900 as fixed overhead. An outside supplier offered to make the product A for $2100 per unit.
Here, Relevant costs for making the product are
1. Variable costs are always relevant as the variable costs will be different if the production level changes.
2. Two thirds of the fixed costs i.e., $900* 2/3 = $600 are unavoidable in both the alternatives and therefore these are irrelevant costs. But one third of $900 i.e., $300 are avoidable if the company accepts the offer and therefore it is relevant cost.
3. Rent is the income foregone if the company makes the product as it is an opportunity cost. Therefore, it is an relevant cost
Differential Analysis |
Make | Buy | |
Direct Material ($360*300 units) | $108000 | |
Direct Labour ($1000*300units) | $300000 | |
Variable Overhead ($240*300 units | $72000 | |
Fixed Overhead ($900*1/3*300 units) | $90000 | |
Purchase Price ($2100*300 units) | $630000 | |
Less: Additional benefit from Buying from outside | -$83000 | |
Total Relevant Costs | $570000 | $547000 |
As the cost of buying is lower than the making, to ontinue making this product, making cost should be lower or equal to the cost of buying.
And therefore,to continue making this product, relevant cost here is the lower of both the cost i.e., $547000.
