Skaros Stairs Co. of Moore designs and builds factory-made premium wooden stairs for homes. The manufactured stair components (spindles, risers, hangers, hand rails) permit installation of stairs of varying lengths and widths. All are of white oak wood. Budgeted manufacturing overhead costs for the year 2011 are as follows.
Overhead Cost Pools
Handling materials 87,200 82,000
Production (cutting, milling, finishing) 230,000 210,000
Setting up machines 91,250 85,000
Inspecting 108,000 90,000
Inventory control (raw materials and finished goods) 134,400 126,000
Utilities 360,000 180,000
Total budget overhead costs $1,067,850 830,000
For the last 4 years, Skaros Stairs Co. has been charging overhead to products on the basis of machine hours. For the year 2011, 100,000 machine hours are budgeted.
Anthony Morse, owner-manager of Skaros Stairs Co., recently directed his accountant, Neal Seagren, to implement the activity-based costing system that he has repeatedly proposed. At Anthony Morse’s request, Neal and the production foreman identify the following cost drivers and their usage for the previously budgeted overhead cost pools
Purchasing Number of orders 600
Handling materials Number of moves 8,000
Production (cutting, milling, finishing) Direct labor hours 100,000
Setting up machines Number of setups 1,250
Inspecting Number of inspections 6,000
Inventory control (raw materials and finished goods) Number of components 168,000
Utilities Square feet occupied 90,000
David Dion, sales manager, has received an order for 280 stairs from Community Builders, Inc., a large housing development contractor. At David’s request, Neal prepares cost estimates for producing components for 280 stairs so David can submit a contract price per stair to Community Builders. He accumulates the following data for the production of 280 stairways.
Direct materials $104,300 103,600
Direct labo r $112,200 112,000
Machine hours 15,400 14,500
Direct labor hours 5,600 5,000
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
Compute the predetermined overhead rate using traditional costing with machine hours as the basis. (Round answer to 2 decimal places, e.g. 2.25.)
$ Per machine hour.
What is the manufacturing cost per stairway under traditional costing? (Use rounded amount from part (a). Round answer to 2 decimal places, e.g. 10.50.)
What is the manufacturing cost per stairway under the proposed activity-based costing? (Round activity-based overhead rates to 2 decimal places, e.g. 10.50. Round final answer to 2 decimal places, 10.50.)
