Question

The following standard costs pertain to a component part manufactured by Bor Co.:

Direct materials $4
Direct labor 10
Factory overhead 40
Standard cost per unit $54
Factory overhead is applied at $1 per standard machine hour. Fixed cost is 60% of applied factory overhead, and is not affected by any make or buy decision. It would cost $49 per unit to buy the part from an outside supplier. In the decision to "make or buy," what is the total relevant unit manufacturing cost?
A. $54
B. $38

Answer 1

Relevant cost= $30

Step-by-step explanation:

Giving the following information:

Direct materials $4

Direct labor 10

Factory overhead 40

Standard cost per unit $54

Fixed cost is 60% of applied factory overhead, and is not affected by any make or buy decision.

The relevant cost in a "make or buy" decision is the cost that can be avoided. Therefore, the fixed manufacturing cost is not relevant.

Relevant overhead= 40*0.4= $16

Relevant cost= 4 + 10 + 16

Relevant cost= $30
