xercise 23-5 Make or buy LO A1

Gelb Company currently manufactures 41,500 units per year of a key component for its manufacturing process. Variable costs are \$5.15 per unit, fixed costs related to making this component are \$79,000 per year, and allocated fixed costs are \$80,500 per year. The allocated fixed costs are unavoidable whether the company makes or buys this component. The company is considering buying this component from a supplier for \$3.70 per unit.

Calculate the total incremental cost of making 41,500 and buying 41,500 units. Should it continue to manufacture the component, or should it buy this component from the outside supplier? (Round "purchase price per unit" answer to 2 decimal places.)

Should it continue to manufacture the component, or should it buy this component from the outside supplier?

 Should Gelb make the part or purchase it from the outside supplier?

SOLUTION

Incremental cost to make-

 Relevant amount per unit (\$) Relevant fixed costs (\$) Total relevant costs (\$) Variable costs (41,500 * \$5.15) 213,725 213,725 Incremental fixed costs 79,000 79,000 Total incremental cost to make 292,725

 Relevant amount per unit (\$) Relevant fixed costs (\$) Total relevant costs (\$) Purchase price (41,500 * \$3.70) 153,550 153,550 Total incremental cost to buy 153,550

Gelb should buy the 41,500 units, as the incremental cost is less than making by \$139,175 (\$292,725 - \$153,550)
