1 Copyright © 2008 Prentice Hall All rights reserved 4-1 Process Costing Chapter 4

2 Copyright © 2008 Prentice Hall All rights reserved 4-2 Objective 1 Distinguish between the flow of costs in process costing and job costing

3 Copyright © 2008 Prentice Hall All rights reserved 4-3 Cost of Goods Sold Manufacturing Wages Materials Inventory Finished Goods Manufacturing Overhead Job Order Costing Work in Process Job 90 Job 91 Job 92

4 Copyright © 2008 Prentice Hall All rights reserved 4-4 Cost of Goods Sold Manufacturing Wages Materials Inventory Finished Goods Process Costing Work in Process, Mixing Dept Work in Process, Molding Dept Work in Process, Packaging Dept Manufacturing Overhead

5 Copyright © 2008 Prentice Hall All rights reserved 4-5 Building Blocks of Process Costing Conversion costs  Costs incurred to convert raw materials into a finished product  Direct labor plus manufacturing overhead Equivalent unit of production  Amount of work done during a period in terms of fully complete units of output Inventory flow assumptions  Weighted average  First-in, first-out

6 Copyright © 2008 Prentice Hall All rights reserved 4-6 Objective 2 Compute equivalent units

7 Copyright © 2008 Prentice Hall All rights reserved 4-7 E4-28: Equivalent Units Calculation Example Step 1: Summarize the flow of physical units Units to account for Units accounted for Blending Department Beginning WIP Units placed in production + Units completed Units in Ending WIP 08,0006,0002,

8 Copyright © 2008 Prentice Hall All rights reserved 4-8 Start Dyes added 100% complete 30% complete 2,000 units started but not finished 6,000 units completed and transferred out Step 2: Compute output in terms of equivalent units

9 Copyright © 2008 Prentice Hall All rights reserved 4-9 E4-28: Equivalent Units for Direct Materials and for Conversion Costs Equivalent units for direct materials: 8,000 units x 100% complete8,000 Equivalent units for conversion costs: 6,000 units x 100% complete6,000 2,000 units x 30% complete600 6,600

10 Copyright © 2008 Prentice Hall All rights reserved 4-10 Objective 3 Use process costing to assign manufacturing costs to units completed and to units in ending work in process inventory in a first department

11 Copyright © 2008 Prentice Hall All rights reserved 4-11 E4-28: Assign manufacturing costs to units completed Step 3: Summarize total costs for which to account: Beginning work in process inventory $ 0 Costs added during May: Direct materials (dyes) 4,800 Direct labor 800 Manufacturing overhead 1,840 Total costs to account for$7,440

12 Copyright © 2008 Prentice Hall All rights reserved 4-12 E4-28 Blending Department Direct Materials Conversion Costs Beginning work in process$ 0 Costs added during period Divide by equivalent units Cost per equivalent unit Step 3: Compute the cost per equivalent unit $4,800 $0.40 $2,640 ÷ 6,600 Refer back to the calculation of equivalent units for Direct Materials.

13 Copyright © 2008 Prentice Hall All rights reserved 4-13 E4-28 Direct Materials Conversion Costs Total Completed and transferred out (6,000) Ending WIP (2,000) Direct materials Conversion costs Total cost of ending WIP Total costs accounted for Step 4: Assign costs to units completed and to units in ending work in process inventory 6,000 x ($ ) $6, x 0.40 $7,440 1, $1,200 Refer back to the equivalent cost per equivalent unit calculation to compute the total cost of direct materials.

17 Copyright © 2008 Prentice Hall All rights reserved 4-17 E4-28: Average Cost Used to assign cost to Transferred Out Average cost per gallon transferred out of blending is: $6,000 ÷ 6,000 gallons = $1.00 per gallon
