Question

Martin, Inc. manufactures bookcases and uses an activity-based costing system. Martin’s activity areas and related data follow:

 

Activity

Budgeted Cost of Activity

Allocation Base

Predetermined Overhead Allocation Rate

 

 

 

 

Materials handling

\( 230,000

Number of parts

\)1.50

Assembly

3,200,000

Number of assembling direct labor hours

16.00

Finishing

   150,000

Number of finished units*

3.00

 

 

*Refers to the number of units receiving the finishing activity, not the number of units transferred to Finished Goods Inventory

Martin produced two styles of bookcases in April: the standard bookcase and an unfinished bookcase, which has fewer parts and requires no finishing. The totals for quantities, direct materials costs, and other data follow:

 

Product

Total Units Produced

Total Direct materials Costs

Total Direct Labor Costs

Total Number of Parts

Total Assembling Direct Labor Hours

 

 

 

 

 

 

Standard bookcase

3,000

\(54,000

\)67,500

9,000

4,500

Unfinished bookcase 

3,500

  56,000

    52,500

7,000

3,500

 

Requirements

1. Compute the manufacturing product cost per unit of each type of bookcase.

Step-by-Step Solution

Verified
Answer

Manufacturing cost per unit 

For Standard bookcase: $72

For Unfinished bookcase: $50

1Step-by-Step-Solution Step 1: Computation of manufacturing product cost for Standard bookcase

Total material handling cost=Predetermined overhead allocation rate×No. of parts used for standatrd book case                                               =$1.5×9,000                                               =$13,500



Total assembling cost=Predetermined over head allocation rate×No. of assembling direct labor hours for standatrd book case                                     =$16×4,500                                     =$72,000




Total finishing cost=Predetermined overhead allocation rate×No. of  finished units for standatrd book case                                 =$3×3,000                                 =$9,000




Total overhead cost=Total material cost+Total assembling cost+Total finishing cost                                =$13,500+$72,000+$9,000                                =$94,500





Total manufacturing cost for standard book case=Direct material cost+Direct labor cost+Overhead cost                                                                                =$54,000+$67,500+$94,500                                                                                =$216,000




Manufacturing cost for per unit=Total manufacturing costNo. of units produced                                                =$216,0003,000                                                =$72

2Step 2: Computation of manufacturing product cost for Unfinished bookcase


Total material handling cost=Predetermined overhead allocation rate×No. of parts used for unfinished book case                                                =$1.5×7,000                                                =$10,500




Total assembling cost=Predetermined overhead allocation rate×No. of assembling direct labor hours for unfinished book case                                   =$16×3,500                                   =$56,000




Total overhead cost=Total material cost+Total assembling cost                                  =$10,500+$56,000                                  =$66,500



Total manufacturing cost for unfinished book case=Directmaterial cost+Direct labor cost+Over head cost                                                                                 =$56,000+$52,500+$66,500                                                                                 =$175,000




Manufacturing cost for per unit=Total manufacturing costNo. of units produced                                                  =$175,0003,500                                                  =$50
