Types of Product Costing Systems

ProcessCosting

Job-order Costing 

  A company produces many units of a singleproduct.

One unit of product is indistinguishable fromother units of product.

The identical nature of each unit of product enablesassigning the same average cost per unit.

Types of Product Costing Systems

ProcessCosting

Job-order Costing 

  Many different products are produced each period.

Products are manufactured to order.

The unique nature of each order requires tracing or allocating costs to each job, and maintaining costrecords for each job.

Compute predeterminedoverhead rates and

explain why estimatedoverhead costs (rather than actual overhead

costs) are used in thecosting process.

Why Use an Allocation Base?

Manufacturing overhead is applied to jobs thatare in process. An allocation base, such asdirect labor hours, direct labor dollars, or 

machine hours, is used to assignmanufacturing overhead to individual jobs.

We use an allocation base because:

1. It is impossible or difficult to trace overhead costs to particular jobs.

2. Manufacturing overhead consists of many different items rangingfrom the grease used in machines to production manager’s salary. 

3. Many types of manufacturing overhead costs are fixed even thoughoutput fluctuates during the period.

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

determined before the period begins.

Estimated total manufacturingoverhead cost for the coming period

Estimated total units in theallocation base for the coming period

POHR =

Ideally, the allocation baseis a cost driver that causes

overhead.

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.

Application of Manufacturing Overhead

 Estimate the level of 

production for the period.

 Estimate the total amount of theallocation base in the denominator that

would be required for that level of production. Estimate the total manufacturing overhead

cost in the numerator that would be incurred

for the estimated amount of the allocation base.

Predetermined overhead rates arecalculated using a three-step process.

Application of Manufacturing Overhead

Overhead applied = POHR × Actual activity

The predeterminedoverhead rate(POHR) isbased on estimates anddetermined before the

period begins.

Actual amount of the allocation isbased upon the actual level of activity.

Interpreting the Average Unit Cost

The average unit cost should not be interpretedas the cost that would actually be incurred if an

additional unit were produced.

Fixed overhead would not change if another unitwere produced, so the incremental cost of another unit is something less than $118.

Rand Company produces gold and silver commemorative medallions. At the beginning of April,Rand company had no finished goods inventory and

one job (Job A) in process, a special mintingof 1,000 gold medallions commemorating the

invention of motion pictures. Manufacturing costsincurred to date on Job A total $30,000. Job A will be

completed in April and Job B, an order for 10,000 sliver medallions commemorating the fall of the Berlin Wall,

• During April, 10,000 machine hours were worked on Job A.

• During April, 5,000 machine hours were worked on Job B.

Job A: $6 per machine hour × 10,000 machine hours = 60,000$

Underapplied or Overapplied Overhead

The difference between the overhead cost applied toWork in Process and the actual overhead costs of aperiod is referred to as either underapplied or 

overapplied overhead.

Underapplied overhead  exists when the amount of overhead applied to jobs

during the period using the

predetermined overheadrate is less than the total

amount of overhead actuallyincurred during the period.

Overapplied overhead  exists when the amount of overhead applied to jobs

during the period using the

predetermined overheadrate is greater than the totalamount of overhead actuallyincurred during the period.

Let’s recall some key facts from the Rand Company example: 

Job A, which consisted of 1,000 goldmedallions, was completed during April,

but Job B was not completed.

The unit product cost for each of the 1,000gold medallions included in Job A was

$158 ($158,000 ÷ 1,000 units).

The overhead for April was underappliedby $5,000.

Let’s recall some key facts from the Rand Company example: 

The beginning work in process inventory was $30,000—thebeginning balance on Job A’s cost sheet. 

There was no beginning finished goods inventory on April 1.

The total manufacturing costs charged to jobs in April was$200,000 (direct materials of $50,000, direct labor of $60,000

and manufacturing overhead applied of $90,000).

The ending work in process inventory is $72,000—theaccumulated cost of Job B.

Manufacturing overhead was underapplied by $5,000.

The Use of Information Technology

Technology plays an important part in many job-order cost systems. When combined with

Electronic Data Interchange (EDI) or a

web-based programming language calledExtensible Markup Language (XML), bar coding eliminates the inefficiencies and

inaccuracies associated with manual clerical

processes.

Predetermined Overhead Rate and Capacity

Calculating predetermined overhead rates usingan estimated, or budgeted amount of theallocation base has been criticized because:

1. Basing the predetermined overhead rate uponbudgeted activity results in product costs thatfluctuate depending upon the activity level.

2. Calculating predetermined rates based upon

budgeted activity charges products for costs thatthey do not use.
