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.

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.

• During April, 10,000 machine hours were worked on Job A.
• During April, 5,000 machine hours were worked on Job B.

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.

gCost of Goods Sold
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.

Multiple Predetermined Overhead Rates
To this point, we have assumed that there is asingle predetermined overhead rate called aplantwide overhead rate.
Large companiesoften use multiple
predetermined
overhead rates,
Which is morecomplex but . . .
it is more accuratebecause it reflectsdifferences across
departments.

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.

Capacity Based Overhead Rates
These criticisms can be overcome by usingestimated total units in the allocation base at
capacity in the denominator of thepredetermined overhead rate calculation.
Let’s look at the difference!
