To assign labor costs to work in process and overhead

Note: if more than one Job is being debited, then subsidiary ledgers forEach job will be debited also. For example if the work in process consisted of$20,000 of payroll going into Job 1 and $5,000 going into job 2, then you would also Debit Job 1 WIP $20,000, and Job 2 WIP $5,000. The work in process and Finished goods are control accounts.

Overhead

Overhead is defined as indirect costs that occur in the factory Examples: Factory supervisor labor,

electricity in factory, insurance in factory, cleaning supplies in factory, copy expense in factory, and so on.

Three Overhead Categories Budgeted overhead

Estimated at the beginning of the year Used for one purpose—calculation of overhead

rate Actual overhead

Calculated at the end of the year Found in the general ledger

Overhead applied The amount of overhead credited from the

Manufacturing Overhead account and debited to Work in Process using a rate and a base

Overhead Rate Formula

Rate = Budgeted Overhead/Base Base should be cost driver Examples of overhead bases include

Direct labor hours Direct labor dollars Total costs Units manufactured And so on

Overhead Example

Jensen Woodworking manufactures custom furniture

Overhead is applied on the basis of direct labor hours

At the beginning of the year the controller prepares the information shown on the next slide

Budget

Estimated direct labor hours = 100,000

Estimated overhead cost = $1,000,000

Overhead rate = 1,000,000/100,000 = $10 per labor hour

Actual Data Year End

Actual direct labor hours worked = 99,500

Actual overhead expense from the general ledger = $1,020,000

Overhead Applied

Formula: Actual hours worked x overhead rate

99,500 x $10 = $995,000 overhead applied

Are we over or under applied?

$25,000

We are under applied by $25,000

Our next step is to close the over

the amount is immaterial)

Brief Exercise Three

In January, Reyes Tool & Dye requisitions raw materials for production as follows: Job one $900, job two $1200, job three $700, and general factory use $600.

Prepare a summary journal entry to record raw material used.

Work in Process Inventory 2,800Manufacturing Overhead 600

Raw Materials Inventory 3,400

Brief Exercise Four

Factory labor data for Reyes Tool & Dye is given in BE2-2.

During January, time tickets show that the factory labor of $5,000 was used as follows: Job 1 $1,200 Job 2 $1,600 Job 3 $1,400 And general factory use $800

Prepare a summary journal entry to record factory labor used.

General Journal Entry

Work in Process Inventory 4,200Manufacturing Overhead 800

Factory Labor 5,000

Brief Exercise Six Marquis Company estimates that

annual manufacturing overhead costs will be $800,000.

Estimated annual operating activity bases are: Direct labor costs $500,000 Direct labor hours 50,000 Machine hours 100,000

Compare the predetermined overhead rate for each activity base.

Brief Exercise Six

Overhead rates using each base: Direct labor costs:

$800,000/$500,000 = $1.60 per direct labor dollar (or 160%)

Direct labor hour: $800,000/50,000 = $16 per direct labor hour

Machine hours: $800,000/100,000 = $8 per machine hour

Exercise 2-2

Miller Manufacturing uses a job order costing system.

On May 1, the company has a balance in work in process inventory of $3,200 and two jobs in process: Job 429: $2,000 Job 430: $1,200

Information from source documents for May is shown on the following slide.

Subtotal $10,400 $12,500

Gen Use 800 1,200

Total $11,200 $13,700

Miller applies overhead to jobs at an overhead rate of 80% of directlabor cost. Job 429 is completed during the month.

Prepare Summary Journals to Record The requisition slips The time tickets The assignment of manufacturing

overhead to jobs The completion of job 429 Then post the entries to work in

process and prove the agreement of the control account with the job cost sheets.
