Process and Job-Order Costing

ProcessCosting

Job-orderCosting

Produces many units of a single product for long periods.

Products are homogeneous.

Cost are allocated to units.

Will be discussed more in Chapter 3.



ProcessCosting

Job-orderCosting

Many different products are produced each period.

Products are manufactured to order.

Cost are traced or allocated to jobs.

Cost records must be maintained for each distinct product or job.



ProcessCosting

Job-orderCosting

Typical job order cost applications: Special-order printing Building construction

Also used in the service industry Hospitals Law firms

Job-Order Cost Accounting

The primary document for tracking the costs associated with a given job is the

job cost sheet.

Note

Why go to all the trouble to fill out a materials requisition form every time someone needs

materials for a job?

Trace costs of materials to particular

jobs.

Prevent pilferage, loss, and waste.Prevent supervisors from stockpiling materials “just in case the stockroom

runs out.”

Maintain control of assets.

Now let’s see how to apply manufacturing overhead to jobs.

Let’s do it


Estimated total manufacturingoverhead cost for the coming period

Estimated total units in theallocation base for the coming period

POHR =

The predetermined overhead rate (POHR) used to apply overhead to jobs

is determined before the period begins.

Application of Manufacturing Overhead

Ideally, the allocation base is a cost driver that causes overhead.


Application of Manufacturing Overhead

Overhead applied = POHR × Actual activity

Actual amount of the allocation base such as units produced, direct

labor hours, or machine hours incurred during the period.

Based on estimates, and determined before the

period begins.


The Need for a Predetermined Manufacturing Overhead Rate

Using a predetermined rate makes itpossible to estimate total job costs sooner.

Actual overhead for the period is notknown until the end of the period.

$$


Note

If we wait until the end of the period, we will know the actual TOTAL overhead cost. However, we still won’t know

the actual overhead cost of a particular job.

Why?

Overhead consists of costs that are either difficult or impossible to trace to particular jobs. Difficult-to-trace costs include the cost of indirect materials like

glue in a furniture factory. Impossible-to-trace costs include fixed common costs like the

property taxes on the factory building and land.


PearCo applies overhead based on direct labor hours. Total estimated overhead

for the year is $640,000. Total estimated labor cost is $1,400,000 and total

estimated labor hours are 160,000.

What is PearCo’s predetermined overhead rate per hour?

Overhead Application Example


For each direct labor hour worked on a job, $4.00 of factory overhead will be

applied to the job.


POHR = $4.00 per DLH

Quick Check

If the number of wooden crates in the order on the previous page is increased or decreased by one unit, what would you expect to happen to the total spending of PearCo?

a. Total spending would probably change by less than $118.

b. Total spending would probably change by about $118.

c. Total spending would probably change by more than $118.

a. Total spending would probably change by less than $118.

b. Total spending would probably change by about $118.

c. Total spending would probably change by more than $118.

Quick Check

Total spending would change by $118 only if all of the costs were variable with respect to the number of units produced. Direct materials is variable, but

much of the overhead and perhaps even direct labor may be fixed.

Let’s return to PearCo and see

PearCo’s actual overhead for the year was $650,000 for a total of 170,000 direct labor hours.

How much total overhead was applied to PearCo’s jobs during the year? Use PearCo’s predetermined

overhead rate of $4.00 per direct labor hour.



SOLUTIONApplied Overhead = POHR × Actual Direct Labor Hours

Applied Overhead = $4.00 per DLH × 170,000 DLH = $680,000



overhead rate of $4.00 per direct labor hour.

Overapplied and Underapplied Manufacturing Overhead - Summary


Tiger, Inc. had actual manufacturing overhead costs of $1,210,000 and a predetermined overhead rate of $4.00 per machine hour. Tiger, Inc. worked 290,000 machine hours during the period. Tiger’s manufacturing overhead is

a. $50,000 overapplied.

b. $50,000 underapplied.

c. $60,000 overapplied.

d. $60,000 underapplied.






Quick Check












Quick Check

Overhead Applied $4.00 per hour × 290,000 hours = $1,160,000

Underapplied Overhead $1,210,000 - $1,160,000 = $50,000


Let’s look at summary journal entries for a job-

order costing system. We’ll omit

the numbers so that we can focus

on accounts.


Cost Flows – Material Purchases

Raw material purchases are recorded in aninventory account.


Direct materials issued to a job increase Work in Process and decrease Raw Materials. Indirect materials used are charged to Manufacturing Overhead and also decrease Raw Materials.

Cost Flows – Material Usage


Cost Flows – Labor

The cost of direct labor incurred increases Work in Process and the cost of indirect labor increases

Manufacturing Overhead.


Cost Flows – Actual Overhead

In addition to indirect materials and indirect labor, other manufacturing overhead costs are charged to the Manufacturing Overhead account as they

are incurred.


Cost Flows – Overhead Applied

Work in Process is increased when Manufacturing Overhead is applied to jobs.


Cost Flows – Period Expenses

Nonmanufacturing costs (period expenses) are charged to expense as they are incurred.


Cost Flows – Cost of Goods Manufactured

As jobs are completed, the Cost of Goods Manufactured is transferred to Finished Goods

from Work in Process.


Cost Flows – Sales

When finished goods are sold, two entries are required: (1) to record the sale; and (2) to record Cost of Goods Sold and reduce Finished Goods.


Job-Order Costing in Service Companies

Job-order costing is a versatile and widely used costing method that may be encountered in virtually

any organization.

In an accounting firm, each client

is a “job.”

In a movie studio, each file produced

is a “job.”

In a law firm, each client is a

“job.”
