Question

Eclipse Motor Company manufactures two types of specialty electric motors, a commercial motor and a residential motor, through two production departments, Assembly and Testing. Presently, the company uses a single plantwide factory overhead rate for allocating factory overhead to the two products. However, management is considering using the multiple production department factory overhead rate method. The following factory overhead was budgeted for Eclipse:

Assembly Department		$280,000
Testing Department		800,000
	Total	$1,080,000

Direct machine hours were estimated as follows:

Assembly Department		4,000	hours
Testing Department		5,000
	Total	9,000	hours

In addition, the direct machine hours (dmh) used to produce a unit of each product in each department were determined from engineering records, as follows:

	Commercial		Residential
Assembly Department	2.0	dmh	3.0	dmh
Testing Department	6.0		1.5
Total machine hours per unit	8.0	dmh	4.5	dmh

a. Determine the per-unit factory overhead allocated to the commercial and residential motors under the single plantwide factory overhead rate method, using direct machine hours as the allocation base.

Commercial	$ per unit
Residential	$ per unit

b. Determine the per-unit factory overhead allocated to the commercial and residential motors under the multiple production department factory overhead rate method, using direct machine hours as the allocation base for each department.

Commercial	$ per unit
Residential	$ per unit

c. Recommend to management a product costing approach, based on your analyses in (a) and (b).

1. The management should consider multiple production department factory overhead rate methods, because this method calculates the cost more accurately and considers the fact that commercial products use more costly overheads than residential products.

2. The management should consider single plantwide factory overhead rate methods, because this method calculates the cost more accurately and considers the fact that the overheads are applied evenly based on the direct labor hours.

3. The management could consider either multiple production department factory overhead rate method or the single plantwide rate, as both these methods have the same effect on the final costs.

Answer 1

ANSWER

a)

Plantwide overhead rate =Estimated overhead /Esimated machine hours

                 = 1080000/9000

                = $ 120 per MH

	Commercial	Residential
Actual MH per unit	8	4.5
Multiply by :Plantwide overhead rate	120	120
Per -unit factory overhead allocated	960	540

b)

Departmental overhead rate :

	Assembly	Testing
Estimated overhead	280000	800000
Divided by :Estimated machine hours each department	4000	5000
Departmental overhead rate	70	160

	Commercial	Residential
Assembly	2*70=140	3*70=210
Testing	6*160= 960	1.5*160= 240
Per -unit factory overhead allocated	1100	450

c)

The management should consider single plantwide factory overhead rate methods, because this method calculates the cost more accurately and considers the fact that the overheads are applied evenly based on the direct labor hours.
