PROCESS COSTING CONCEPT Process Costing Used by manufacturers

PROCESS COSTING

CONCEPT Process Costing Used by manufacturers who mass produce large quantities of identical units in a continuous flow. Process costing involves averaging costs for a particular period in order to obtain departmental unit costs.

Job Order and Process Cost Systems Compared Job Order Cost System Direct materials Job Cost Sheets Dept. A and Dept. B Direct labor Factory overhead Finished goods Process Cost System Direct materials Dept. A Direct Factory labor overhead Dept. B Direct Factory labor overhead Finished goods

CHARACTORISTICS OF PROCESS COSTING � The cost of production report is used to collect , summarize and compute total and unit costs. � Total costs charged to the department is divided by total computed production of the department in order to determine a unit cost for a specific period. � Costs of completed units of a department are transferred to the next processing department in order to arrive at the total costs of the finished products during a period.

THE PROCEDURES OF PROCESS COSTING � Accumulate materials , labor and factory overheads costs by departments � Determine a unit cost for each department � Transfer costs from one department to the next and to finished goods � Assign costs to the inventory of work still in process .

PRODUCT FLOW �Three product flow formats associated with process costing �Sequential product flow �Parallel product flow �Selective product flow

SEQUENTIAL PRODUCT FLOW � In a sequential product flow, each item manufactured goes through the same set of operations. e. g � Materials are placed into production in the Blending department and labor and FOH are added. When the work is finished in the Blending department , it moves to the Testing department. The same procedure is applied again and after the completion of work , it moves to the Terminal department. After this department the product is completed and becomes the part of the finished goods.

PARALLEL PRODUCT FLOW �In a parallel product flow, certain portions of the work are done simultaneously and then brought together in a final process or processes for completion and transfer to the finished goods.

SELECTIVE PRODUCT FLOW �The product moves to different departments within the plant, depending upon the desired final product. E. g meat processing

MATERIAL COSTS An entry to record direct materials used in a period is as follows:

LABOR COSTS � Summary labor charges are made to departments through an entry which distributes the direct material payroll:

FACTORY OVERHEAD COSTS �Predetermined overhead rates for producing departments should be used if: �Production is not stable �Factory overhead , especially fixed overhead , is a significant cost. �The use of predetermined rates is highly recommended for improving cost control and facilitating cost analysis

ACTUAL FACTORY OVERHEAD

APPLIED FACTORY OVERHEAD

COST OF PRODUCTION REPORT � A departmental cost of production report shows all costs chargeable to a department. � It is the most conveniant vehicle for presenting and disposing of costs accumulated during the month.

COST OF PRODUCTION REPORT � A cost of production report shows: � Total and unit costs tranferred to it from a preceding department � Materials, labor, and factory overheads added by the department � Unit costs added by the department. � Total and unit costs accumulated to the end of the operations in the department � The cost of work in process inventories � Cost tranferred to the succeeding department or to a finished goods store room

COST OF PRODUCTION REPORT �Information in the cost of production report is adjusted for equivalent production. �To condense the illustrated cost of production report , only total materials , labor and factory overhead charged to the departments are considered.
