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

2. Suppose that pre-manufacturing activities, such as product design, were assigned to the standard bookcases at \(5 each and to the unfinished bookcases at \)3 each. Similar analyses were conducted of post-manufacturing activities such as distribution, marketing, and customer service. The post-manufacturing costs were \(24 per standard bookcase and \)18 per unfinished bookcase. Compute the full product costs per unit.

Step-by-Step Solution

Verified
Answer

Full product cost per unit

For standard bookcase: $101

For unfinished bookcase: $71

1Step-by-Step-Solution Step 1: Computation of full product cost for standard bookcase

Manufacturing cost for standard bookcase computed in earlier part: $216,000


Product design cost=Cost per unit×No. of units produced                                =$5×3,000                                =$15,000



Analysis cost=Cost per unit×No. of units produced                    =$24×3,000                    =$72,000




Total full product cost=Manufacturing cost+Product  design cost+Analysis cost                                   =$216,000+$15,000+$72,000                                   =$303,000



Full product cost per unit=Total full product costNo. of units produced                                         =$303,0003,000                                         =$101

2Step 2: Computation of full product cost for unfinished bookcase

Manufacturing cost for unfinished bookcase computed in earlier part: $175,000


Product design cost=Cost per unit×No. of units produced                                 =$3×3,500                                 =$10,500


Analysis cost=Cost per unit×No. of units produced                       =$18×3,500                       =$63,000


Total full product cost=Manufacturing cost+Product design cost+Analysis cost                                     =$175,000+$10,500+$63,000                                     =$248,500


Full product cost per unit=Total full product costNo. of units produced                                          =$248,5003,500                                          =$71
