Job-Order Costing Many jobs are worked on during each period, with each job having different production requirements. Costs are accumulated by job. The job cost sheet is the key document for accumulating costs. Units costs are computed by job on a job cost sheet. Process Costing A homogeneous product is produced on a continuous basis or for long periods of time. Costs are accumulated by department. The departmental production report is the key document showing the accumulation and disposition of costs. Unit costs are computed by department on production reports. Job-Order v. Process Costing
Calculation of Equivalent Units Beginning Work-in-Process Inventory: = XXX Physical Units X 100% Started and Completed in Current Period: Physical Units X 100% = XXX Ending Work-in-Process Inventory: Percent of work completed in the current period Physical Units X XXX = Equivalent Units of Production XXX

Cost Per Equivalent Unit (EU) of Production Production Cost for Component (include costs carried forward from beginning WIP) Equivalent Units of Production for Component = Equivalent Unit Cost for Component Note: Equivalent units and cost per equivalent unit are often computed for direct materials and conversion costs (direct labor & manufacturing overhead). Conversion costs may also be calculated separately.

Costs Accounted For Transferred Out: Transferred Out EU x Cost Per EU = XXX Cost in Ending Work-in-Process Inventory: Ending WIP EU x Cost Per EU = XXX XXX Note: Total cost is computed for direct materials and conversion costs (direct labor & manufacturing overhead). Conversion costs may also be calculated separately.
