Question

Gilberto Company currently manufactures 90,000 units per year of one of its crucial parts. Variable costs are $3.20 per unit, fixed costs related to making this part are $100,000 per year, and allocated fixed costs are $87,000 per year. Allocated fixed costs are unavoidable whether the company makes or buys the part. Gilberto is considering buying the part from a supplier for a quoted price of $4.40 per unit guaranteed for a three-year period. Calculate the total incremental cost of making 90,000 and buying 90,000 units. Should the company continue to manufacture the part, or should it buy the part from the outside supplier?

Answer 1

Answer:

Part 1

total incremental cost of making 90,000 units =  $388,000

total incremental cost of buying 90,000 units = $396,000

Part 2

There is a cost advantage of $8,000 of making than buying, therefore  the company should continue to manufacture the part.

Explanation:

total incremental cost of making 90,000 units

Variable costs are ($3.20 x 90,000 units)    $288,000

Fixed Costs                                                      $100,000

Total                                                                 $388,000

total incremental cost of buying 90,000 units

Purchase Price ($4.40 x 90,000 units)          $396,000

Total                                                                 $396,000

Decision :

There is a cost advantage of $8,000 of making than buying, therefore  the company should continue to manufacture the part.
