Question

X Company currently buys a part from a supplier for $13.72 per unit but is considering making the part itself next year. This year, they purchased 3,300 units of this part; next year, they think they will need 3,800 units. Estimated costs to make the part are:


Of the estimated fixed overhead, $6,468 are common costs that would be allocated to the part; the rest would be additional fixed overhead costs. X Company currently rents unused factory space for $2,600; it will have to use this space to make the part. If X Company makes the part instead of buying it, it will save

Explanation / Answer

Per Unit

For 3,800 units

Direct material

$              3.74

$               14,212

Add: Direct Labor

$              4.88

$               18,544

Add: Variable overhead

$              2.60

$                 9,880

Add: Fixed overhead

$          3.7421

$               14,220

Total

$          14.962

$               56,856

Fixed overhead per unit = ($ 13,200 - $ 6,468)/3,300 = $ 6,732/3,300 = $ 2.04

*Fixed overhead = $ 6,468 + (2.04 x 3,800) = $ 6,468 + 7,752 = $ 14,220

Cost for purchasing = $ 13.72 x 3,800 = $ 52,136

Cost of making = Total cost for making + rent opportunity = $ 56,856 + $ 2,600 = $ 59,456

Save in making = $ 52,136 - $ 59,456 = ($ 7,320)
