Question

Pottery Ranch Inc. has been manufacturing its own finials for its curtain rods. The company is currently operating at 100% of capacity, and variable manufacturing overhead is charged to production at the rate of 61% of direct labor cost. The direct materials and direct labor cost per unit to make a pair of finials are $4 and $5, respectively. Normal production is 26,400 curtain rods per year.

A supplier offers to make a pair of finials at a price of $13.30 per unit. If Pottery Ranch accepts the supplier’s offer, all variable manufacturing costs will be eliminated, but the $40,400 of fixed manufacturing overhead currently being charged to the finials will have to be absorbed by other products.

Required:
Prepare the incremental analysis for the decision to make or buy the finials.

Production costs:

Variable manufacturing costs per unit:

Direct materials per unit $4.00

Direct labor per unit $5.00

Variable manufacturing per unit $3.05

Total variable manufacturing costs $12.05 $13.30 $1.25

Annual units of curtain rods 26,400 26,400 26,400

Variable manufacturing costs $318,120 $351,120 $33,000

Step-by-step explanation:

a) Data and Calculations:

Production capacity = 100%

Variable manufacturing overhead = 61% of direct labor cost

Direct materials per unit = $4

Direct labor per unit = $5

Variable manufacturing per unit = $3.05 (61% of $5)

Total variable manufacturing cost per unit = $12.05

Normal production per year = 26,400 units

Total variable manufacturing costs = $318,120 ($12.05 * 26,400)

Fixed manufacturing overhead = $40,400
