Question

X Company is considering buying a part next year that they currently make. This year's per-unit production costs for 3,400 units were:

A company has offered to supply this part for $13.17 per unit. If X Company buys the part, $8,289 of the fixed overhead can be avoided. Also if X Company buys the part, it can use the freed-up resources to increase production of another product, resulting in additional contribution margin of $2,700. Production next year is also expected to be 3,400 units.


If X Company buys the part instead of making it, it will save?

At what production level would X Company be indifferent between making and buying the part?

Materials Direct labor [all variable] Variable overhead Fixed overhead Total production costs $3.92 4.19 2.70 4.60 $15.41

Explanation / Answer

(1) If company buy it then buying cost is 3400 x $13.17 = $44778

If company produce it then production cost (3400 x 10.81) + $8289 + $2700 = $47743

Thus If X Company buys the part instead of making it, it will save $47743 – $44778 = $2965

(2) At what production level would X Company be indifferent between making and buying the part;

2965 / (13.17 – 10.81)   = 1256 units approx. thus production should be 3400 units + 1256 units = 4656 Units
