Question

Derby Inc. manufactures a product which contains a small part. The company has always purchased this motor from a supplier for $125 each. Derby recently upgraded its own manufacturing capabilities and now has enough excess capacity (including trained workers) to begin manufacturing the motor instead of buying it. The company prepared the following per unit cost projections of making the motor, assuming that overhead is allocated to the part at the normal predetermined overhead rate of 150% of direct labor cost.Direct material $ 38Direct labor 50Overhead (fixed and variable) 75Total $ 163The required volume of output to produce the motors will not require any incremental fixed overhead. Incremental variable overhead cost is $21 per motor. What is the effect on income if Derby decides to make the motors

Answer 1

Answer:

Income will be higher by $16 per unit

Explanation:

As per the data given in the question,

Direct material = $38

Direct labor = $50

Overhead = $21

Total variable cost = $38 + $50 + $21

= $109

Cost of supply = $125

Income increased per unit = cost of supply - total variable cost  

=$125 - $109

= $16

Because the cost of inhouse is lower therefore net income will be more by $16 per unit
