After studying this chapter you will be able to understand: When is a yard not a yard? How do they differ? Cost flows in process costing system, costing system comparison, process costing issues, process costing recap. | TOPIC FOCUS ON PROCESS COSTING WHEN IS A YARD NOT A YARD? Bradley Textile Mills started working on 500,000 yards of jersey fabric The month-end report showed only 450,000 yards in process So how do you reconcile the 50,000 yard difference when you know there was no spoilage? HOW DO THEY DIFFER? Custom Cabinetmaker Textile Mill Each job is unique Product costs are easy to trace to a specific job/product Fabric is mass-produced Impossible to trace product costs to a specific yard of fabric How do you determine the cost of a product in a mass-production environment? COST FLOWS IN PROCESS COSTING SYSTEM COSTING SYSTEM COMPARISON Process Costing Job Order Costing Similarities Objective To accumulate and assign manufacturing costs to products To accumulate and assign manufacturing costs to products Product costs Direct material, direct labor, manufacturing overhead Direct material, direct labor, manufacturing overhead Cost flows From RM to WIP to FG to COGS From RM to WIP to FG to COGS Differences Production schedule Identical products produced over a long period, often in a continuous production process Many different products produced, each with different materials, labor, and/or overhead requirements Cost accumulation By production department By job Key document Department production report Job cost sheet THINK ABOUT IT When are direct materials added in this process? What are conversion costs and when are they incurred? Which of these departments could have ending WIP? How is the product in Mixing WIP ending inventory different from the product being transferred from mixing to baking? PROCESS COSTING ISSUES Materials costs versus conversion costs Timing differences lead to costing differences Equivalent units Often not the same as the number of physical units May be different for direct materials and for conversion 10 cookies that are 60% complete = 6 equivalent units (10 × 60%) EQUIVALENT UNITS Two units that are 50% complete have required the same inputs and effort as one unit that is 100% complete. So these two physical units are one equivalent unit. # of physical units × % of completion = Equivalent Units BRADLEY TEXTILE MILLS JUNE RESULTS CALCULATING UNIT COST Beginning WIP $ + Costs added during the period Completed physical units + Ending WIP equivalent units Weaving Dept. – Materials Work in process, June 1 $ 37,120 + Costs added during June 565,020 = Total costs to be accounted for $266,800 Completed yards transferred 400,000 + Ending WIP equivalent yards 60,000 ÷ Equivalent yards 460,000 = Cost per equivalent unit $ PROCESS COSTING RECAP Calculate the physical unit flow Calculate the equivalent units of production Calculate the cost per equivalent unit Allocate the equivalent unit costs of production Reconcile the costs of production Repeat for each production department
