  2. Learning Objectives • Record the flow of materials, labor, and overhead through a process cost system. • Compute the equivalent units of production using the weighted-average method. • Compute the cost per equivalent unit using the weighted-average method. • Assign costs to units using the weighted-average method. • Compute the equivalent units of production using the FIFO method. • Compute the cost per equivalent unit using the FIFO method. • Assign costs to units using the FIFO method • Allocate service department costs to operating departments using the direct method. • To allocate service department costs to operating departments using the step-down method.

  3. 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.

  4. + = 1 Equivalent Units – The Basic Idea Two half completed products are equivalent to one completed product. So, 10,000 units 70% completeare equivalent to 7,000 complete units.

  5. 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

  6. 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

  7. Calculating Equivalent Units Equivalent units can be calculated two 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.

  8. 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.

  11. Weighted-Average Example Double Diamond Skis reported the following activity in Shaping and Milling Department for the month of May:

  12. Weighted-Average Example The first step in calculating the equivalent units is to identify the units completed and transferred out of the Department in May (4,800 units)

  13. Weighted-Average Example The second step is to identify the equivalent units of production in ending work in process with respect to materials for the month (160 units) and add this to the 4,800 units from step one.

  14. Weighted-Average Example The third step is to identify the equivalent units of production in ending work in process with respect to conversion for the month (100 units) and add this to the 4,800 units from step one.

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

  16. Weighted-Average Example Materials 5,000 Units Started EndingWork in Process400 Units40% Complete BeginningWork in Process200 Units55% Complete 4,800 Units Startedand Completed 4,800 Units Completed 400 × 40% 160 Equivalent Units 4,960 Equivalent units of production

  18. Compute and Apply Costs Beginning work in process: 200 units Materials: 55% complete $ 9,600 Conversion: 30% complete 5,575 Production started during May 5,000 units Production completed during May 4,800 units Costs added to production in May Materials cost $ 368,600 Conversion cost 350,900 Ending work in process 400 units Materials: 40% complete Conversion: 25% complete

  19. 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 :

  30. Operation Costing Operation cost is a hybrid of job-order and process costing because it possesses attributes of both approaches Operation costing is commonly used when batches of many different products pass through the same processing department.

  31. FIFO vs. Weighted-Average Method The FIFO method (generally considered more accurate that the weighted-average method) differs from the weighted-average method in two ways: • The computation of equivalent units. • The way in which the costs of beginning inventory are treated in the cost reconciliation report.

  32. Equivalent Units – FIFO Method Let’s revisit the Double Diamond Skis example. Assume the following activity is reported in Shaping and Milling Department for May:

  33. Equivalent Units – FIFO Method Step 1: Determine equivalent units needed to complete beginning inventory.

  34. Equivalent Units – FIFO Method Step 2: Determine units started and completed during the period.

  35. Equivalent Units – FIFO Method Step 3: Add the equivalent units in ending working in process inventory.

  36. FIFO Example Materials 5,000 Units Started EndingWork in Process400 Units40% Complete BeginningWork in Process200 Units55% Complete 4,600 Units Startedand Completed 200 × 45% 90 Equivalent Units 4,600 Units Completed 400 × 40% 160 Equivalent Units 4,850 Equivalent units of production

  37. FIFO Example Conversion 5,000 Units Started EndingWork in Process400 Units25% Complete BeginningWork in Process200 Units30% Complete 4,600 Units Startedand Completed 200 × 70% 140 Equivalent Units 4,600 Units Completed 400 × 25% 100 Equivalent Units 4,840 Equivalent units of production

  38. Equivalent Units: Weighted Average vs. FIFO As shown below, the equivalent units in beginning inventory are subtracted from the equivalent units of production per the weighted-average method to obtain the equivalent units of production under the FIFO method.

  39. Cost per Equivalent Unit - FIFO Let’s revisit the Double Diamond Skis Shaping and Milling Department for the Month of May to prepare our production report. Beginning work in process: 200 units Materials: 55% complete $ 9,600 Conversion: 30% complete 5,575 $15, 175 Production started during May 5,000 units Production completed during May 4,800 units Costs added to production in May Materials cost $ 368,600 Conversion cost 350,900 Ending work in process: 400 units Materials: 40% complete Conversion: 25% complete

  40. Cost perequivalent unit Cost added during the period = Equivalent units of production Cost per Equivalent Unit - FIFO The formula for computing the cost per equivalent unit under FIFO method is :

  41. Cost per Equivalent Unit - FIFO

  42. Applying Costs - FIFO Step 1: Record the equivalent units of production in ending work in process inventory.

  43. Applying Costs - FIFO Step 2: Record the cost per equivalent unit.

  44. Applying Costs - FIFO Step 3: Compute the cost of ending work in process inventory.

  45. Cost of Units Transferred Out Step 1: Record the cost in beginning work in process inventory.

  46. Cost of Units Transferred Out Step 2: Compute the cost to complete the units in beginningwork in process inventory.

  47. Cost of Units Transferred Out Step 3: Compute the cost of units started and completed this period.

  48. Cost of Units Transferred Out Step 4: Compute the total cost of units transferred out.
