Job Order Costing

Cost AccountingFoundations and Evolutions

Kinney, Prather, Raiborn

Learning Objectives (1 of 3)

• Contrast the job order and process costing systems and their valuation methods

• Define what the term ‘job’ means

• Explain the purpose of the documents used in a job order costing system

Learning Objectives (2 of 3)

• List the journal entries used to accumulate costs in a job order costing system

• Identify how technology impacts the gathering and use of information in job order costing systems

Learning Objectives (3of 3)

• Explain how standard costs are used in a job order costing system

• Describe how job order costing information supports management decision making

• Explain how losses are treated in a job order costing system

Job Order or Process CostingJob Order

• Small quantities• Batches of

identifiable, tailor-made products

• User-specific services

• Tracks costs by job

Job Order or Process CostingJob Order

• Small quantities• Batches of

identifiable, tailor-made products

• User-specific services

• Tracks costs by job

Process

• Large quantities

• Homogeneous goods

• Tracks costs by batch of goods by department

Job Order Costing

• A job is a single unit or group of units identifiable as being produced to distinct customer specifications

• A job can be a– Client– Engagement– Project – Contract

Costing Systems

Job order costing Process costing

COLA

Product Costing

• Cost identification

• Cost measurement

• Product cost assignment

Methods of Product Costing

• Cost Accumulation System defines

– cost object – method of assigning costs to production

• Valuation Method specifies

– how product costs will be measured

Six Possibilities

COSTING SYSTEM

Valuation Methods

• Actual– Actual direct material

– Actual direct labor

– Actual overhead

• Normal– Actual direct material

– Actual direct labor

– Predetermined overhead

• Standard– Standard direct material

– Standard direct labor

– Standard overhead

The Difference

Job Order Costing System

• Each job is a cost object

• Costs are accumulated for each job

• A job can consist of one or more units of output

• There is a subsidiary ledger for each job

Job Order Costing System

WIP ControlJob 2Job 1 Job 3

Job 1 + Job 2 + Job 3 = WIP Control

WIP Subsidiary Ledger

Material Requisition Form

• Tracks who is responsible for materials

• Verifies flow of materials from warehouse to department to job

Job Order Cost Sheet

• All financial information about a job– direct material (from material requisition)– direct labor (from time sheets or labor tickets)– applied overhead– budgeted cost information

• All financial information about a job– direct material (from material requisition)– direct labor (from time sheets or labor tickets)– applied overhead– budgeted cost information

• When job is complete, use job order cost sheet to analyze actual costs to budgeted costs

Standard Cost System

• Actual cost

• Normal cost

• Standard cost– Predetermined norms (or standards) for

materials, labor, and overhead– Compare actual costs to standard costs -

difference is a variance

Management Use of Job Order Costing Systems

• Estimate future job costs

• Establish realistic bids and selling prices

• Develop budgets and standards

• Compare actual costs to estimated costs

• Determine which jobs are profitable

• Manage inventory

Product and Material Losses

• Shrinkage – Evaporation– Leakage– Oxidation

• Production errors– Defects can be economically reworked– Spoilage cannot be economically reworked

Product and Material Losses

• Normal Loss – expected during production

• Abnormal Loss – exceeds that expected during production

Normal Loss

• Anticipated on all jobs– Include cost when calculating predetermined

overhead application rate– Include cost less the estimated disposal value

• Specific to a job– Applied to the specific job– Include cost less the estimated disposal value

Abnormal Spoilage

• Period cost – includes cost of abnormal loss less any disposal value
