Chapter FourSystems Design:Process Costing4-2Similarities Between Job-Order and Process CostingBoth systems assign material,labor and overhead costs to products as a way to calculate the unit product cost.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.4-3Differences Between Job-Order and Process CostingProcess 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 are worked on each period.Process costing systems accumulate costs by department.Job-order costing systems accumulate 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.4-4Process 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.Quick Check 4-5Processing DepartmentsAny unit in an

FlowsCosts associated with the goods that are completed during the period are transferred to finished goods inventory.4-25Equivalent Units of ProductionEquivalent 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.4-26Equivalent Units The Basic IdeaTwo half completed products are equivalent to one completed product.So,10,000 units 70%completeare equivalent to 7,000 complete units.+=14-27 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.15,000Quick Check 4-28Calculating Equivalent UnitsEquivalent 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.4-29Learning Objective 2Compute the equivalent units of production using the weighted-average method.4-30Equivalent Units of ProductionWeighted-Average MethodThe 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.4-31Treatment of Direct LaborDirect labor costsare becoming smallin comparison toother productcosts in processcost systems.DirectMaterialsType of Product CostDollar

to identify the units completed and transferred out of the Department in May(4,800 units)Weighted-Average Example4-35The second step is to identify the equivalent units 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.Weighted-Average Example4-36Weighted-Average ExampleThe third step is to identify the equivalent units 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.4-37Equivalent units of production will always be equal:Units completed and

than the weighted-average method)differs from the weighted-average method in two ways:1.The computation of equivalent units.The computation of equivalent units.2.The way in which the costs of

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.4-62Learning Objective 6Compute the cost per equivalent unit using the FIFO method.4-63Cost per Equivalent Unit-FIFOLets revisit the Double Diamond Skis Shaping and Milling Department for the

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.4-78End of
