(a)

Thakin Stairs Co. designs and builds factory-made premium wooden stairways for homes. The manufactured stairway components (spindles, risers, hangers, hand rails) permit installation of stairways of varying lengths and widths. All are of white oak wood. Budgeted manufacturing overhead costs for the year 2014 are as follows.

For the last 4 years, Thakin Stairs Co. has been charging overhead to products on the basis of machine hours. For the year 2014, 100,000 machine hours are budgeted.

Jeremy Nolan, owner-manager of Thakin Stairs Co., recently directed his accountant, Bill Seagren, to implement the activity-based costing system that he has repeatedly proposed. At Jeremy Nolan’s request, Bill and the production foreman identify the following cost drivers and their usage for the previously budgeted overhead cost pools.

Steve Hannon, sales manager, has received an order for 250 stairways from Community Builders, Inc., a large housing development contractor. At Steve’s request, Bill prepares cost estimates for producing components for 250 stairways so Steve can submit a contract price per stairway to Community Builders. He accumulates the following data for the production of 250 stairways.
Direct materials $104,300 Direct labor $113,100 Machine hours 15,300 Direct labor hours 5,600 Number of purchase orders 60 Number of material moves 800 Number of machine setups 100 Number of inspections 450 Number of components 16,000 Number of square feet occupied 8,000

Explanation / Answer

Formula for Predetermined overhead rate under traditional costing is,

Predetermined overhead rate = Estimated Manufacturing overhead cost / estimated number of units in the allocation base.

To compute above formul;a, we need Estimated Manufacturing overhead cost and estimated number of units in the allocation base:

Estimated Manufacturing overhead cost = $1,081,600 (given directly) and

estimated number of units in the allocation base, here we need to take total machine hours as the basis, that means Total estimated machine hours = 100,000 machine hours are budgeted (already given)

Therefore,
Predetermined overhead rate = Estimated Manufacturing overhead cost / estimated number of units in the allocation base.

= $1,081,600 / 100,000 machine hours

= 10.816 = $10.82per machine hour (rounded off).

Therefore, Predetermined overhead rate = $10.82per machine hour
