Systems Design: Process Costing

1. Systems Design: Process Costing Chapter 4

2. Both systems assign material, labor and overhead costs to products and they provide a mechanism for computing unit product costs. Both systems use the same manufacturing accounts, including Manufacturing Overhead, Raw Materials, Work in Process, and Finished Goods. The flow of costs through the manufacturing accounts is basically the same in both systems. Similarities Between Job-Order and Process Costing

3. Process costing is used when a single product is produced on a continuing basis or for a long period of time. Job-order costing is used when many different jobs having different production requirements are worked on each period. Process costing systems accumulate costs by department. Job-order costing systems accumulated costs by individual jobs. Process costing systems compute unit costs by department. Job-order costing systems compute unit costs by job on the job cost sheet. Differences Between Job-Order and Process Costing

4. Quick Check  Process costing is used for products that are: a. Different and produced continuously. b. Similar and produced continuously. c. Individual units produced to customer specifications. d. Purchased from vendors.

6. Processing Departments Any unit in an organization where materials, labor or overhead are added to the product. The activities performed in a processingdepartment are performed uniformly on allunits of production. Furthermore, the output ofa processing department must be homogeneous. Products in a process costing environment typically flow in a sequence from one departmentto another.

7. Learning Objective 1 Record the flow of materials, labor, and overhead through a process costing system.

11. T-Account and Journal Entry Views of Process Cost Flows For purposes of this example, assume there are two processing departments – Departments A and B. We will use T-accounts and journal entries.

24. Equivalent Units of Production Equivalent units are the product of the number of partially completed units and the percentage completion of those units. We need to calculate equivalent units because a department usually has some partially completed units in its beginning and ending inventory. These partially completed units complicate the determination of a department’s output for a given period and the unit cost that should be assigned to that output.

25. + = 1 Equivalent Units – The Basic Idea Two half completed products are equivalent to one complete product. So, 10,000 units 70% completeare equivalent to 7,000 complete units.

26. Quick Check  For the current period, Jones started 15,000 units and completed 10,000 units, leaving 5,000 units in process 30 percent complete. How many equivalent units of production did Jones have for the period? a. 10,000 b. 11,500 c. 13,500 d. 15,000

27. Quick Check  For the current period, Jones started 15,000 units and completed 10,000 units, leaving 5,000 units in process 30 percent complete. How many equivalent units of production did Jones have for the period? a. 10,000 b. 11,500 c. 13,500 d. 15,000 10,000 units + (5,000 units × 0.30) = 11,500 equivalent units

28. Calculating Equivalent Units Equivalent units can be calculatedtwo ways: The First-In, First-Out Method – FIFO is covered in the appendix to this chapter. The Weighted-Average Method – This method will be covered in the main portion of the chapter.

29. Learning Objective 2 Compute the equivalent units of production using the weighted-average method.

30. Equivalent Units of ProductionWeighted-Average Method The weighted-average method . . . Makes no distinction between work done in prior or current periods. Blends together units and costs from prior and current periods. Determines equivalent units of production for a department by adding together the number of units transferred out plus the equivalent units in ending Work in Process Inventory.

33. Weighted-Average – An Example Smith Company reported the following activity in the Assembly Department for the month of June:

34. Weighted-Average – An Example The first step in calculating the equivalent units is to identify the units completed and transferred out of Assembly Department in June (5,400 units)

35. Weighted-Average – An Example The second step is to identify the equivalent unitsof production in ending work in processwith respect to materialsfor the month (540 units) and adding this to the 5,400 units from step one.

36. Weighted-Average – An Example The third step is to identify the equivalent unitsof production in ending work in processwith respect to conversion for the month (270 units) and adding this to the 5,400 units from step one.

37. Weighted-Average – An Example Equivalent units of production always equals: Units completed and transferred + Equivalent units remaining in work in process

40. Learning Objective 3 Compute the cost per equivalent unit using the weighted-average method.

41. Compute and Apply Costs Beginning Work in Process Inventory: 400 units Materials: 40% complete $ 6,119 Conversion: 20% complete $ 3,920 Production started during June 6,000 units Production completed during June 5,400 units Costs added to production in June Materials cost $ 118,621 Conversion cost $ 81,130 Ending Work in Process Inventory: 900 units Materials: 60% complete Conversion: 30% complete

42. Cost of beginningWork in ProcessInventory Cost perequivalent unit + Cost added during the period = Equivalent units of production Compute and Apply Costs The formula for computing the cost per equivalent unit is:

43. Compute and Apply Costs Here is a schedule with the cost and equivalent unit information.

44. Compute and Apply Costs Here is a schedule with the cost and equivalent unit information. $124,740 ÷ 5,940 units = $21.00 $85,050 ÷ 5,670 units = $15.00 Cost per equivalent unit = $21.00 + $15.00 = $36.00
