Question

Valley Company makes 10,000 units per year of a part it uses in the products it manufactures. The unit product cost of this part is computed as follows:

An outside supplier has offered to sell the company all of these parts it needs for $42.10 a unit. If the company accepts this offer, the facilities now being used to make the part could be used to make more units of a product that is in high demand. The additional contribution margin on this other product would be $36,000 per year.

If the part were purchased from the outside supplier, all of the direct labor cost of the part would be avoided. However, $5.40 of the fixed manufacturing overhead cost being applied to the part would continue even if the part were purchased from the outside supplier. This fixed manufacturing overhead cost would be applied to the company's remaining products.

The answers I came up were (a) $41.70 and (b) Advantage, $32,000

Valley Company makes 10,000 units per year of a part it uses in the products it manufactures. The unit product cost of this part is computed as follows:

Direct materials Direct labor Variable manufacturing overhead $ 13.00 20.60 2.80 Fixed manufacturing overhead10.70 Unit product cost $47.10

Explanation / Answer

Calculate relevant cost per unit on make or buy :

b) If purchasing the part rather than making it then advantage of (41.70-42.10*10000)-36000 = 32000

Make Buy Direct material 13.00 Direct labour 20.60 Variable manufacturing overhead 2.80 Fixed manufacturing overhead 5.30 Purchase cost 42.10 Total relevant cost per unit 41.70 42.10
