Overhead Applied to Jobs, Departmental Overhead Rates

Xania Inc. uses a normal job-order costing system. Currently, a plantwide overhead rate based on machine hours is used. Xanias plant manager has heard that departmental overhead rates can offer significantly better cost assignments than a plantwide rate can offer. Xania has the following data for its two departments for the coming year:

	Department A		Department B
Overhead costs (expected)	$125,000		$50,000
Normal activity (machine hours)	10,500		6,800

Required:

1. Compute a predetermined overhead rate for the plant as a whole based on machine hours. Round your answer to two decimal places. $fill in the blank 1 per machine hour

2. Compute predetermined overhead rates for each department using machine hours. (Note: Round to two decimal places, if necessary.)

Department A	$fill in the blank 2 per machine hour
Department B	$fill in the blank 3 per machine hour

3. Conceptual Connection: Job 73 used 20 machine hours from Department A and 50 machine hours from Department B. Job 74 used 50 machine hours from Department A and 20 machine hours from Department B. Compute the overhead cost assigned to each job using the plantwide rate computed in Requirement 1. Repeat the computation using the departmental rates found in Requirement 2. Round final answers to the nearest cent, if necessary.

	Job 73	Job 74
Plantwide	$fill in the blank 4	$fill in the blank 5
Departmental	$fill in the blank 6	$fill in the blank 7

Which of the two approaches gives the fairer assignment?

Departmental ratesPlantwide ratePlantwide rate

4. Conceptual Connection: Repeat Requirement 3, assuming the expected overhead cost for Department B is $75,000 (not $50,000). Round overhead rates to the nearest cent.

	Job 73	Job 74
Plantwide	$fill in the blank 9	$fill in the blank 10
Departmental	$fill in the blank 11	$fill in the blank 12

For this company, would you recommend departmental rates over a plantwide rate?
