Basic Costing Terminology…
 Several key points from prior chapters:
 Cost Objects – including responsibility centers,
departments, customers, products, etc.
 Direct Costs and Tracing – materials and labor
 Indirect Costs and Allocation – overhead

…logically extended
 Cost Pool – any logical grouping of related cost
objects
 Cost-allocation Base – a cost driver is used as a
basis upon which to build a systematic method of
distributing indirect costs
 For example, let’s say that direct labor hours cause
indirect costs to change. Accordingly, direct labor
hours will be used to distribute or allocate costs among
objects based on their usage of that cost driver

Costing Systems
 Job-Costing: system accounting for distinct
cost objects called Jobs. Each job may be
different from the next, and consumes
different resources
 Wedding announcements, aircraft, advertising
 Process-Costing: system accounting for mass
production of identical or similar products
 Oil refining, orange juice, soda pop

Costing Approaches
 Actual Costing – allocates:
 Indirect costs based on the actual indirect-cost
rates times the actual activity consumption
 Normal Costing – allocates:
 Indirect costs based on the budgeted indirect-
cost rates times the actual activity
consumption
 Both methods allocate Direct costs to a cost
object the same way: by using actual direct-
cost rates times actual consumption

Seven-step Job Costing
1. Identify the Job to be costed
2. Identify the Direct Costs of the Job
3. Select the Cost-Allocation base(s) to use for
allocating Indirect Costs to the Job
4. Match Indirect Costs to their respective
Cost-Allocation base(s)

Seven-step Job Costing (continued)
5. Calculate an Overhead Allocation Rate:
• Actual OH Costs ÷ Actual OH Allocation
Base
6. Allocate Overhead Costs to the Job:
• OH Allocation Rate x Actual Base Activity For the
Job
7. Compute Total Job Costs by adding all
direct and indirect costs together

Journal Entries
 Journal entries are made at each step of the
production process
 The purpose is to have the accounting
system closely reflect the actual state of the
business, its inventories and its production
processes

Journal Entries, continued
 All Product Costs are accumulated in the
Work-in-Process Control account
 Direct Materials used
 Direct Labor incurred
 Factory Overhead allocated or applied
 Actual Indirect Costs (overhead) are
accumulated in the Manufacturing Overhead
Control account

 Purchase of Materials on credit:
 Materials Control XX
Accounts Payable Control XX
 Requisition of Direct and Indirect Materials (OH) into
production:
 Work-in-Process Control X
Manufacturing Overhead Control Y
Materials Control Z

 Incurred Direct and Indirect (OH) Labor
Wages
Manufacturing Overhead Control Y
Wages Payable Control Z

 Incurring or recording of various actual
Indirect Costs:
 Manufacturing Overhead Control X
Salaries Payable Control A
Accounts Payable Control B
Accumulated Depreciation Control C
Prepaid Expenses Control D

 Allocation or application of Indirect Costs
(overhead) to the Work-in-Process account
is based on a predetermined overhead rate
Manufacturing Overhead Allocated X
 Note: actual overhead costs are never posted
directly into Work-in-Process

 Products are completed and transferred out
of production in preparation for being sold
 Finished Goods Control X
Work-in-Process Control X

 Products are sold to customers on credit
 Accounts Receivable Control X
Sales X
 And the associated costs are transferred to an
expense (cost) account
 Cost of Goods Sold Y
Finished Goods Control Y
 Note: The difference between the sales and cost of
goods sold amounts represents the gross margin
(profit) on this particular transaction

Accounting for Overhead
 Recall that two different overhead accounts
were used in the preceding journal entries:
 Manufacturing Overhead Control was debited
for the actual overhead costs incurred.
 Manufacturing Overhead Allocated was
credited for estimated (budgeted) overhead
applied to production through the Work-in-
Process account.

 Actual costs will almost never equal budgeted
costs. Accordingly, an imbalance situation
exists between the two overhead accounts
 If Overhead Control > Overhead Allocated,
this is called Underallocated Overhead
 If Overhead Control < Overhead Allocated,
this is called Overallocated Overhead

 This difference will be eliminated in the end-
of-period adjusting entry process, using one
of three possible methods
 The choice of method should be based on
such issues as materiality, consistency, and
industry practice

Three Methods for Adjusting the
Over/Underapplied Situations
 Adjusted Allocation Rate Approach – all allocations
are recalculated with the actual, exact allocation rate
 Proration Approach – the difference is allocated
between Cost of Goods Sold, Work-in-Process, and
Finished Goods based on their relative sizes
 Write-Off Approach – the difference is simply written
off to Cost of Goods Sold
