Presentation

To Teach Job Costing

Objective 1

Job order costing

Process costing

Cost Systems

• There are two basic systems used by manufacturers to assign costs to their products:

Chopping Mixing and Canning

Process Costing Example

• Laxmi Foods Company produces a garlic flavored tomato sauce.

• Production of the sauce requires two major processes:

$20,000 ÷ 100,000 = $0.20/pint

Process Costing Example

• Assume that Laxmi incurred $20,000 in the Mixing and Canning process to mix 100,000 pints of tomato sauce.

• What is the Mixing and Canning cost per pint?

Job Costing

• It is used by a manufacturer who produces products as individual units or in distinct batches or jobs.

Job Costing Example

• Ram, Sham, and Co. is a small furniture manufacturing business in Texas.

• They received an order for 10 chairs from a customer in Kansas City.

$500 ÷ 10 = $50/chair

Job Costing Example

• Total cost for the job was $500.

• How much was the cost per chair?

Job Costing

• Job cost record is a document used to accumulate the costs of a job.

Objective 2

Materials Cost

• Companies using job costing often use a perpetual system to account for direct materials.

• A materials requisition is used to request transfer of materials to the production floor.

Materials Cost Example

• Alec Clothing Co. purchased raw materials on account for $15,000.

• Materials costing $10,000 were requisitioned for production.

• Of this total, $2,000 was indirect materials.

Manufacturing Overhead

Materials Cost Example

Labor Costs

• Labor costs are accumulated using the payroll register and time records.

• Labor time records identify the employee, the amount of time spent, and the cost charged to each job.

Labor Cost Example

• The company incurred $30,000 of manufacturing wages for all jobs.

• Assume that $25,000 can be traced directly to the jobs and $5,000 is for indirect labor.

Objective 3

Manufacturing Overhead(Deprec.-Plant and Equipment) 20,000

Accumulated Depreciation(Plant and Equipment) 20,000

To record plant and equipment depreciation

Manufacturing Overhead Costs

• The company incurred $20,000 of plant equipment depreciation.

Estimated overhead ÷ Estimated base = Rate

Manufacturing Overhead Rate

• At the beginning of the year, a predetermined manufacturing overhead application rate is computed.

• This rate is used to apply overhead to all jobs completed during the year.

Six Steps in Allocating Manufacturing Overhead Cost

1 Estimate total overhead for the period.

2 Select an overhead allocation base.

3 Estimate total quantity of the overhead allocation base.

4 Compute the predetermined overhead rate.

Six Steps in Allocating Manufacturing Overhead Cost

5 Obtain actual quantities of the overhead allocation base.

6 Allocate manufacturing overhead by multiplying the predetermined manufacturing overhead rate by the actual quantity of the allocation base that pertains to each job.

$243,000 ÷ 4,500 = $54

Manufacturing Overhead Example

• Alec Clothing Co.’s total estimated overhead for the year equals $243,000.

• The predetermined overhead rate is based on 4,500 direct labor hours.

• What is the predetermined overhead rate?

Work-in-Process Inventory 10,800Manufacturing Overhead 10,800

To record overhead applied to Job 51

Manufacturing Overhead Example

• Assume that Job 51 used 200 direct labor hours.

• What is the journal entry to record the manufacturing overhead applied?

Objective 4

Accounting for Finished Goods, Sales, and Cost of Goods Sold

• As jobs are completed they are transferred to finished goods inventory.

• In addition to the overhead applied to Job 51, direct labor was $4,000 and direct materials totaled $30,000.

• How much was transferred to Finished Goods Inventory?

• What are the journal entries?

Disposing of Underallocated or Overallocated Overhead

• Suppose that the company incurred $232,000 of actual manufacturing overhead during the year, and that actual direct labor hours worked were 4,000.

• The actual manufacturing overhead rate would have been $232,000 ÷ 4,000 = $58.

• The predetermined rate was $54.

Disposing of Underallocated or Overallocated Overhead

• How much overhead was allocated to the various jobs?

• 4,000 direct labor hours × $54 = $216,000

• What is the underallocated amount?

• $232,000 actual – $216,000 allocated = $16,000

Disposing Underallocated Overhead to Cost of Goods Sold

Disposing Overallocated Overhead to Cost of Goods Sold

• Assume the opposite situation in which allocated overhead is $232,000 and actual overhead is $216,000.

• How do we dispose of overallocated overhead?• Debit the Manufacturing Overhead account and

credit the Cost of Goods Sold account to decrease the costs that went to the income statement.

Objective 5

Job Costing in a Nonmanufacturing Company

• How is direct labor traced to individual jobs in a nonmanufacturing company?

• Employees complete a weekly time record.• Jim, Abby, and Associates is a firm

specializing in composing and arranging music parts for different clients.

• Musician Judy Lopez’s salary is $80,000 per year.

80,000 ÷ 2,000 = $40


• Assuming a 40-hour workweek and 50 workweeks in each year gives a total of 2,000 available working hours per year (40 hours × 50 weeks).

• What is her hourly rate?

Advertising $ 15,000Depreciation 6,000Maintenance 12,000Office rent 60,000Office support 47,000Travel 20,000Total indirect costs $160,000


• Jim and Abby estimated the indirect costs that will be incurred in 2006.

160,000 ÷ 8,000 = $20


• Assume that they estimate that the musicians will work 8,000 direct labor hours in 2006.

• What is the predetermined indirect cost rate?

Direct Labor: 25 hours × $40 = $1,000Indirect costs: 25 hours × $20 = 500Total costs: $1,500


• Records show that Judy Lopez worked 25 hours servicing Los Abuelos Music Co.

• What is the total cost assigned to this client?
