JOB ORDER COSTINGPRESENTED BY: ARPANA KUMARI(20013) DIMPLE KUMARI(20015) CHANDAN DEV(20014) KARTHIK B.(20016)

definition A costing System in which cost are collected and assigned to units of production for each individual job. Job costing is a product costing system that accumulates costs and assigns them to a specific job.

Advantages of job order costing Offers a detailed analysis of the costs of materials, labor cost and overheads by functions and nature. Makes it possible to appraise the profitability of a job. Facilitates the estimation of the cost of a similar job.

cont Allocates overheads on the basis of a predetermined rate. Costing makes easy to identify spoilage and defects to take corrective actions. Evaluates efficiency of different types of jobs with cost records by using statistical techniques.

Disadvantages of job order costing Needs a great deal of clerical work. Ascertainment of overhead rate needs allocation and apportionment of the overheads from service department to production department . Strict control of costs associated with a job is difficult.

Job order costing system Job order costing system is used in situations where many different products are produced each period. In a job order costing system, costs are traced to the jobs and then the costs of the job are divided by the number of units in the job to arrive at an average cost per unit. Job Order Costing System is also extensively used in service industries.

Problems in job order costing system The record keeping and cost assignment problems are more complex in a job order costing system when a company sells many different products and services than when it has only a single product or service. Since the products are different, the costs are typically different. Consequently, cost records must be maintained for each distinct product or job.

The same basic purpose exists in both systems. Job-Order Costing Vs. Process Costing - Similarities

3

Both systems maintain and use the same manufacturing accounts.

4The flow of costs through the accounts is basically the same.

The same basic purpose exists in both systems. Job-Order Costing Vs. Process Costing - Similarities

1

To assign direct material, direct labor and manufacturing overhead to products.

2To provide a mechanism for computing unit cost.

Differences arise from two factors . . .These units are indistinguishable from one another.

2

The flow of units in a process costing system is more or less continuous.

Job-Order Costing Vs. Process Costing - Differences

Differences

JOB ORDER COST FLOWS The cost flow parallels the physical flow of the materials as they are converted into finished goods. Manufacturing costs are assigned to Work in Process.

Cost of completed jobs is transferred to Finished Goods Inventory. When units are sold, the cost is transferred to Cost of Goods Sold.

JOB ORDER COST FLOWSOverview

Two Major Steps in Flows of Costs Accumulate the manufacturing costs incurred Raw materials Factory Labor Manufacturing Overhead Assign the accumulated costs to the work done

Application of Manufacturing Overhead

Application of Factory Overhead To apply overhead cost to each job, normal costing requires a per product rate, which is often called a predetermined rate (since it is calculated at the beginning of the accounting period) The predetermined factory overhead rate is an estimated factory overhead rate used to apply factory overhead cost to a specific job4-15

ASSIGNING MANUFACTURING COSTS TO WORK IN PROCESSTrack of job cost through source documents Job Cost Sheet: It is subsidiary to the work-in process account and is primary document for accumulating all costs related to a particular job.

Material Requisition Form: The cost of direct material is assigned to any job by the use of a source document known as material requisition form.

Job Time Tickets : The cost of direct labor are assigned to individual jobs through a source document known as job time tickets.

Flow of Documents in a Job-Order Costing System A sales order is prepared as a basis for issuing a . . . Production Order

Sales Order A production order initiates work on a job, whereby costs are charged through:

Materials Requisition Form

Direct Labor Time Ticket

Predetermined Overhead Rates

Job Cost Sheet

Direct Materials Direct Labor Mfg. Overhead Work-inProcess Finished Goods Cost-of Goods Sold

Direct Materials Direct Labor Mfg. Overhead Work-inProcess Finished Goods Cost-of Goods Sold

Job Costing in Service Industries Job costing in service industries uses recording procedures and accounts similar to those in manufacturing except for direct materials involved. In service industries, the primary focus is on direct labor. The overhead costs are usually applied to jobs based on direct labor-hours or dollars.
