Question

Exercise 2-15 Plantwide and Departmental Predetermined Overhead Rates; Job Costs [LO2-1, LO2-2, LO2-3, LO2-4]

[The following information applies to the questions displayed below.]

Delph Company uses a job-order costing system and has two manufacturing departments—Molding and Fabrication. The company provided the following estimates at the beginning of the year:

  

	Molding		Fabrication			Total
Machine-hours		31,000		41,000		72,000
Fixed manufacturing overhead costs	$	740,000	$	210,000	$	950,000
Variable manufacturing overhead cost per machine-hour	$	5.50	$	5.50

  

During the year, the company had no beginning or ending inventories and it started, completed, and sold only two jobs—Job D-70 and Job C-200. It provided the following information related to those two jobs:

  

Job D-70:	Molding		Fabrication		Total
Direct materials cost	$	378,000	$	322,000	$	700,000
Direct labor cost	$	230,000	$	160,000	$	390,000
Machine-hours		24,000		7,000		31,000

  

Job C-200:	Molding		Fabrication		Total
Direct materials cost	$	290,000	$	230,000	$	520,000
Direct labor cost	$	160,000	$	270,000	$	430,000
Machine-hours		7,000		34,000		41,000

Delph had no underapplied or overapplied manufacturing overhead during the year.

Exercise 2-15 Part 1

Required:

1. Assume Delph uses a plantwide predetermined overhead rate based on machine-hours.

a. Compute the plantwide predetermined overhead rate.

b. Compute the total manufacturing cost assigned to Job D-70 and Job C-200.

Answer 1

a)

Calculation of Plantwide Predetermined Overhead Rate
Total fixed cost	$             950,000.00
Variable cost(72,000*5.5)	$             396,000.00
Total Manufacuring cost(A)	$         1,346,000.00
Total Machine hours(B)	72,000.00
Predetermined Overhead Rate (C )=(A)/(B)	$                     18.694

b)

Calculation of total manufacturing cost assigned
	Job D-70	Job C-200
Direct Material Cost	$       700,000	$       520,000
Direct Labor Cost	$       390,000	$       430,000
Manufacturing Overhead	$       579,528	$       766,472
Total Cost Assigned	$    1,669,528	$    1,716,472
