3 Product Costing n Product Costing is the mapping and allocating of costs to a specific product n Its purpose is to provide executives with critical information including: n How to minimize costs n How to price a product competitively and profitably n There are two main methodologies of Product Costing 1. Job-Order Costing each job is different 2. Process Costing many of the same products

4 Job Order Costing n Job-Order Costing is the costing methodology applied in companies in the following circumstances: n Produce many different products or packages n Manufacture to order so each job is different n Examples would be: n SNC (engineering and construction) n Airbus (aircraft) n Other? n In these cases, a company needs to know, often on an order by order basis, what are the costs associated with fulfilling the order n Cost records for each job will be required to support decision making and billing of the customer

5 Process Costing n Process Costing is the costing methodology applied in companies in the following circumstances: n Produce many units of a single product n Each unit is substantially similar to other units n Examples would be: n Lenovo (PC manufacturing) n Frito lay (Snacks and beverages) n Others? n That each of these products are substantially the same, managers are able to apply the same average cost to each unit

6 Similarities & Differences Between Job- Order and Process Costing n Similarities n Both are Product Costing systems assigning material, labour and overhead to products n Both systems use the same manufacturing accounts n The flow of costs are very similar in both systems n Differences n Process Costing is used for single products which run continuously (versus differing products/packages) n Process Costing tracks cost by department (versus by job) n Tracks unit cost by department (versus by job sheet)

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

8 Processing Departments n The same three inputs go into Work in Process as in Job-Order Costing n In Process Costing, Processing Departments must be identified n A Processing department is any department in which the activities and output are uniform: n Assembly Department n Testing Department n Others? n Inventories get transferred from one department through to the other n Costs are accumulated in each department

9 Flow of Materials, Labor and Overhead Costs Direct Materials Costs are traced and applied to departments in a process cost system. Direct Labor Processing Department Finished Goods Manufacturing Overhead Cost of Goods Sold

10 Process Cost Flows: The Flow of Raw Materials (in T-account form) Raw Materials Direct Materials Work in Process Department A Direct Materials Work in Process Department B Direct Materials

11 Process Cost Flows: The Flow of Labor Costs (in T-account form) Salaries and Wages Payable Direct Labor Work in Process Department A Direct Materials Direct Labor Work in Process Department B Direct Materials Direct Labor

12 Process Cost Flows: The Flow of Manufacturing Overhead Costs (in T- account form) Manufacturing Overhead Actual Overhead Overhead Applied to Work in Process Work in Process Department A Direct Materials Direct Labor Applied Overhead Work in Process Department B Direct Materials Direct Labor Applied Overhead

13 Process Cost Flows: Transfers from WIP- Dept. A to WIP-Dept. B (in T-account form) Work in Process Department A Direct Materials Direct Labor Applied Overhead Transferred to Dept. B Work in Process Department B Direct Materials Direct Labor Applied Overhead Transferred from Dept. A Department A Department B

14 Process Cost Flows: Transfers from WIP- Dept. B to Finished Goods (in T-account form) Work in Process Department B Direct Materials Direct Labor Applied Overhead Transferred from Dept. A Cost of Goods Manufactured Finished Goods Cost of Goods Manufactured

15 Process Cost Flows: Transfers from Finished Goods to COGS (in T-account form) Work in Process Department B Direct Materials Direct Labor Applied Overhead Transferred from Dept. A Cost of Goods Manufactured Cost of Goods Sold Cost of Goods Sold Finished Goods Cost of Goods Manufactured Cost of Goods Sold

17 Valuing Inventory in Process Costing System n Just as with Job Order Costing, n There must be a method for valuing inventory accounts and Cost of Goods Manufactured to get COGS n Raw Materials n WIP n Finished Goods n There are two main methodologies n Weighted Average method n First in First Out method n First, look at the Weighted Average method n Requires the concept of Equivalent Units of Production

18 Equivalent Units of Production Equivalent units are the product of the number of partially completed units and the percentage completion of those units. 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.

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

20 Two Methodologies for Calculating Costed Equivalent Units n There are two main methodologies for Calculating Equivalent Units n Weighted Average n No distinction between work done or costs incurred in prior and current periods n Equivalent units of production is the sum of n Units transferred out to the next department or finished goods, plus n Ending Equivalent Units in WIP n First-In-First-Out (FIFO) n Distinguishes between work done and costs in different periods

21 Treatment of Direct Labor Dollar Amount Direct Labor Direct Materials Conversion Direct Labor Manufacturing Overhead Direct labor and manufacturing overhead may be combined into one classification of product cost called conversion costs. Type of Product Cost

22 Weighted Average Method n Direct Labour and Manufacturing Overhead are often consolidated into a single account called Conversion n This is a simplifying step taken as DL is often very small relative to DM and Manufacturing Overhead in these types of businesses Department B - Weighted Average Percentage Complete Number of Partially Complete Products Units Materials Conversion Beginning WIP % 30% Units beginning production 40,000 Units complete/transfered out 38, % 100% Ending WIP 2,300 35% 30%

23 Weighted Average Method Equivalent Units of Production n Calculation of Equivalent Units of Production = Units transferred out plus ending Equivalent Units (definitional) Department B - Weighted Average Percentage Complete Materials Conversion Units complete/transfered out 38,500 38,500 Ending WIP 2,300 * 35% 805 2,300 * 30% 690 Equivalent Units of Production for Period 39,305 39,190 Assume: Cost of beginning WIP-Materials was $4,000; WIP-Conversion was $9,000 Cost of additional production Materials was $200,000, Conversion was $250,000 What was the cost per equivalent unit?

24 Weighted Average Method Cost per equivalent unit = Cost of beginning work in process inventory + Cost added during the period Equivalent units of production Department B - Weighted Average Percentage Complete Materials Conversion Units complete/transfered out 38,500 38,500 Ending WIP 2,300 * 35% 805 2,300 * 30% 690 Equivalent Units of Production for Period 39,305 39,190 Cost of beginning WIP-Materials was $4,000; WIP-Conversion was $9,000 Cost of additional production Materials was $200,000, Conversion was $250,000

25 Weighted Average Method Cost per equivalent unit = Cost of beginning work in process inventory + Cost added during the period Equivalent units of production Department B - Weighted Average Materials Conversion Cost of Beginning WIP 4,000 9,000 Period production costs 200, ,000 Total costs 204, ,000 Equivalent units 39,305 39,190 Cost per Equivalent Unit Total cost per EU $ 11.80

26 Computing the Cost of Units Transferred Out & Ending WIP Department B - Weighted Average Cost of Ending WIP Inventory and Transferred Units Materials Conversion Total Ending WIP Ending Equivalent Units Cost per Equivalent Unit Cost of ending WIP 4,178 4,560 8,738 Units completed & transferred Units transfered 38,500 38,500 Cost per Equivalent Unit Cost of units transferred out 199, , ,262 n These totals will be entered into the Balance Sheet accounts

27 Reconciling Costs The following exercise will provide a reconciliation, a check on your calculations Department B - Weighted Average Reconciliation of Costs Costs to be accounted for: Beginning WIP 13,000 Costs added during period 450,000 Total 463,000 Costs accounted for: Cost of ending WIP 8,738 Costs of units transferred out 454,262 Total 463,000

29 FIFO Method

30 April 21, 2014 n Process Costing FIFO Inventory Method n What is FIFO? n FIFO versus Average Cost method n When should FIFO be used? n Journal entries n Calculating balances by the FIFO Cost method

31 FIFO n FIFO is a method of calculating inventory balances n First in - First out n Materials, labour and overhead is drawn into production over time n FIFO attributes the earlier costs drawn to the inventory that leaves the department or finished goods first n FIFO is generally considered more accurate than the Weighted Average method n Better attributes costs in any given period n Identifies cost overruns more quickly and distinctly allowing managers to address problems with minimal delay

32 Equivalent Units FIFO Method n Back to Department B from the Weighted Average Example Department B - FIFO Percentage Complete Number of Partially Complete Products Units Materials Conversion Beginning WIP % 30% Units beginning production 40,000 Units complete/transfered out 38, % 100% Ending WIP 2,300 35% 30% n This will help us compare the methodologies side-by-side

33 FIFO Equivalent Units of Production n Calculation of Equivalent Units of Production Department B - FIFO Percentage Complete Materials Conversion Beginning WIP - % incomplete 800 * 50% * 70% 560 Units started & completed 37,700 37,700 Ending WIP 2,300 * 35% 805 2,300 * 30% 690 Equivalent Units of Production for Period 38,905 38,950 Note: Units started & completed = units started less ending WIP units

34 Equivalent Units of Production - Reconciling WA to FIFO n The fundamental difference between Equivalent Units of Production under FIFO is that beginning WIP is subtracted from the WA conclusion Department B - Weighted Average to FIFO Equivalent units - Weighted Average 39,305 39,190 less Beginning WIP Equivalent Units of Production for Period 38,905 38,950

35 Calculating Unit Cost - FIFO Method Cost per equivalent unit = Cost added during the period Equivalent units of production Department B - FIFO Materials Conversion Period production costs 200, ,000 Equivalent units 38,905 38,950 Cost per Equivalent Unit Total cost per EU $ n Note: Equivalent Units are usually not the same

36 Computing the Cost of Ending WIP - FIFO Department B - FIFO Cost of Ending WIP Inventory Materials Conversion Total Ending WIP Ending Equivalent Units Cost per Equivalent Unit Cost of ending WIP 4,138 4,429 8,567 n This total will be entered into the Balance Sheet accounts

37 Computing the Cost of Units Transferred Out - FIFO Department B - FIFO Cost of Tranferring Units Units completed & transferred Cost in Beginning WIP 4,000 9,000 13,000 Cost to complete Beginning WIP Equivalent Units to Complete Cost per Equivalent Unit Cost of units started and completed 2,056 3,594 5,651 Cost units completed in period Units started and completed 37,700 37,700 Cost per Equivalent Unit Cost of units started and completed 193, , ,782 Total Cost of Units Transferred Out 454,433 n This total will be entered into the Balance Sheet accounts

38 Reconciling Costs As with the Weighted Average Method, the following exercise will provide a reconciliation, a check on your calculations for the FIFO Method Department B - FIFO Reconciliation of Costs Costs to be accounted for: Beginning WIP 13,000 Costs added during period 450,000 Total 463,000 Costs accounted for: Cost of ending WIP 8,567 Costs of units transferred out 454,433 Total 463,000

39 A Comparison of Costing Methods In a lean production environment, FIFO and weighted-average methods yield similar unit costs. When considering cost control, FIFO is superior to weighted-average because it does not mix costs of the current period with costs of the prior period.
