Calculating Departmental Overhead Rates Using Post-Allocation Costs

Valron Company has two support departments, Human Resources and General Factory, and two producing departments, Fabricating and Assembly.

	Support Departments		Producing Departments
	Human Resources	General Factory	Fabricating	Assembly
Direct costs	$160,000	$340,000	$114,600	$93,000
Normal activity:
Number of employees		60	80	170
Square footage	1,000		5,700	13,300

The costs of the Human Resources Department are allocated on the basis of number of employees, and the costs of General Factory are allocated on the basis of square footage. Valron Company uses the direct method of support department cost allocation. Solve for the allocated costs to Fabricating and Assembly using the direct method of support department cost allocation. The Fabricating Department overhead rate is based on normal activity of 82,000 machine hours. The Assembly Department overhead rate is based on normal activity of 160,000 direct labor hours.

Job 316 required six machine hours in Fabricating and four direct labor hours in Assembly. Total direct materials cost $120, and total direct labor cost was $80.

Required:

1. Calculate the overhead rate for Fabricating based on machine hours and the overhead rate for Assembly based on direct labor hours. If required, round your answers to the nearest cent. Use the rounded values for subsequent calculations.

	Overhead Rate
Fabricating department	$ per mach. hr.
Assembly department	$ per DLH

2. Using the overhead rates calculated in Requirement 1, calculate the cost of Job 316. If required, round your answer to the nearest cent. $

3. What if Job 316 had required one machine hour in Fabricating and four direct labor hours in Assembly? Direct labor and direct materials costs remained the same. Calculate the new cost of Job 316. If required, round your answer to the nearest cent. $
