Building-Block Concepts
of Costing Systems
Cost pool
A grouping of individual cost items
Cost allocation base
This is normally the cost driver of an
indirect cost and it is use to allocate a
cost pool of the said indirect cost
4-3
Learning Objective 2
Distinguish between job
costing and process costing.

Job-Costing and
Process-Costing Systems
Job-costing
system
Distinct units of a
product or service
Process-costing
system
Masses of identical
or similar units of
a product or service

Learning Objective 3
Outline a seven-step
approach to job costing.
4-6
Seven-Step Approach
to Job Costing
Step 1:
Identify the chosen cost object (job).
Step 2:
Identify the direct costs of the job.
Step 3:
Select the cost-allocation base(s).
Step 4:
Identify the indirect costs associated
with each cost-allocation base.
4-7
Seven-Step Approach
to Job Costing
Step 5:
Compute the rate per unit of each allocation base
Step 6:
Compute the indirect costs allocated to the job.
Step 7:
Compute the total cost of the job by adding all
direct and indirect costs assigned to the job.
4-8
General Approach to Job Costing
A manufacturing company is planning to sell
a batch of 25 special machines (Job 650) to a
retailer for $114,800.
Step 1:
The cost object is Job 650.
Step 2:
Direct costs are: Direct materials = $50,000
Direct manufacturing labor = $19,000
4-9
General Approach to Job Costing
Step 3:
The cost allocation base is machine-hours.
Job 650 used 500 machine-hours.
2,480 machine-hours were used by all jobs.
Step 4:
Manufacturing overhead costs were $65,100.
Step 5:
Actual indirect cost rate is
$65,100 ÷ 2,480 = $26.25 per machine-hour.
Step 6:
$26.25 per machine-hour × 500 hours = $13,125

Gross margin
$ 32,675
What is the gross margin percentage?
$32,675 ÷ $114,800 = 28.5%

Learning Objective 4
Distinguish actual costing
from normal costing.
4 - 14
Costing Systems
Actual Costing - allocates indirect costs based
on the actual indirect-cost rate(s) times the actual
quantity of the cost-allocation base(s).
Normal costing allocates indirect costs based
on the budgeted indirect-cost rate(s) times the
actual quantity of the cost allocation base(s).
4 - 15
Normal Costing
Assume that the manufacturing company budgets
$60,000 for total manufacturing overhead costs
and 2,400 machine-hours.
What is the budgeted indirect-cost rate?
$60,000 ÷ 2,400 = $25 per hour
How much indirect cost was allocated to Job 650?
500 machine-hours × $25 = $12,500

End-Of-Period Adjustments
How was the allocated overhead determined?
2,480 machine-hours × $25 budgeted rate = $62,000
$65,100 – $62,000 = $3,100 (underallocated)
Actual manufacturing overhead costs of $65,100
are more than the budgeted amount of $60,000.
Actual machine-hours of 2,480 are more than
the budgeted amount of 2,400 hours.
4 - 41
End-Of-Period Adjustments
Approaches to disposing underallocated
or overallocated overhead:
1. Adjusted allocation rate approach
2. Proration approaches
3. Immediate write-off to Cost of Goods
Sold approach
4 - 42
1. Adjusted Allocation
Rate Approach
Actual manufacturing overhead ($65,100)
exceeds manufacturing overhead allocated
($62,000) by 5%.
3,100 ÷ 62,000 = 5%
Actual manufacturing overhead rate is $26.25
per machine-hour ($65,100 ÷ 2,480) rather
than the budgeted $25.00.
4 - 43
1.Adjusted Allocation
Rate Approach
The manufacturing company could increase
the manufacturing overhead allocated to
each job by 5%.
Manufacturing overhead allocated to Job 650
under normal costing is $12,500.
$12,500 × 5% = $625
$12,500 + $625 = $13,125, which equals
actual manufacturing overhead.
4 - 44
2. Proration Approach
Basis to prorate under- or overallocated overhead:
(A)– total amount of manufacturing overhead
allocated (before proration)*
(B)– ending balances of Work in Process, Finished
Goods, and Cost of Goods Sold
* - This method gives the same result as the adjusted
allocation-rate approach (approach #1)
4 - 45
2. Proration Approach “A”
Assume the following manufacturing
overhead component of year-end
balances (before proration):
Work in Process
$33,500 54.03%
Finished Goods
16,000 25.81%
Cost of Goods Sold
12,500 20.16%
Total
$62,000 100.00%

equal to the actual manufacturing overhead of $13,125.

Learning Objective 7
Apply variations from
normal costing.
4 - 51
Variations of Normal Costing
Direct costs could be allocated based on a budgeted
rate and not using actual direct costs. This is possible
in a service company e.g. Accounting firm.
Home Health budget includes the following:
Total direct labor costs: $400,000
Total indirect costs: $96,000
Total direct (professional) labor-hours: 16,000
4 - 52
Variations of Normal Costing
What is the budgeted direct labor cost rate?
$400,000 ÷ 16,000 = $25
What is the budgeted indirect cost rate?
$96,000 ÷ 16,000 = $6
4 - 53
Variations of Normal Costing
Suppose a patient uses 25 direct labor-hours.
Assuming no other direct costs, what is the
cost to Home Health?
Direct labor:
25 hours × $25 = $625
Indirect costs: 25 hours × $6 = 150
Total
$775
