Problem 13.22 - Page 499 Activity-based costing versus traditional overhead allocation methods Woodland Industries manufactures and sells custom-made windows. Its job costing system was designed using an activity-based costing approach. Direct materials and direct labor costs are accumulated separately, along with information concerning three manufacturing overhead cost drivers (activities). Assume that the direct labor rate is $15 per hour and that there were no beginning inventories. The following information was available for 2016, based on an expected production level of 50,000 units for the year, which will require 200,000 direct labor hours: Activity Cost Driver Budgeted Costs for 2016 Cost Driver Used as Allocation Base Cost Allocation Rate Materials handling $ 250,000 Number of parts used $ 0.20 per part Cutting and lathe work 1,750,000 Number of parts used 1.40 per part Assembly and inspection 4,000,000 Direct labor hours 20.00 per hour The following production, costs, and activities occurred during the month of July: Units Produced Direct Materials Costs Number of Parts Used Direct Labor Hours 3,200 $107,200 70,400 13,120 Required: Calculate the total manufacturing costs and the cost per unit of the windows produced during the month of July (using the activity-based costing approach). Assume instead that Woodland Industries applies manufacturing overhead on a direct labor hours basis (rather than using the activity-based costing system previously described). Calculate the total manufacturing cost and the cost per unit of the windows produced during the month of July. (Hint: You will need to calculate the predetermined overhead application rate using the total budgeted overhead costs for 2016.) Compare the per unit cost figures calculated in parts a and b. Which approach do you think provides better information for manufacturing managers? Explain your answer.
