Basic Costing Terminology…Several key points from prior chapters:
Cost Objects - including responsibility centers, departments, customers, products, etc.
Direct costs and tracing – materials and laborIndirect costs and allocation - overhead

…logically extendedCost Pool – any logical grouping of related
cost objectsCost-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 SystemsJob-Costing: system accounting for distinct
cost objects called Jobs. Each job may be different from the next, and consumes different resourcesWedding announcements, aircraft, advertising
Process-Costing: system accounting for mass production of identical or similar productsOil refining, orange juice, soda pop

Costing ApproachesActual 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 Costing1. Identify the Job that is the Chosen Cost
Object2. Identify the Direct Costs of the Job3. Select the Cost-Allocation base(s) to use for
allocating Indirect Costs to the Job4. 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 EntriesJournal entries are made at each step of the
production processThe purpose is to have the accounting system
closely reflect the actual state of the business, its inventories and its production processes.

Accounting for OverheadRecall 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.
![Page 25: Chapter 04final](https://reader033.fdocuments.in/reader033/viewer/2022060109/555880b3d8b42aad358b496b/html5/thumbnails/25.jpg)

Accounting for OverheadActual costs will almost never equal budgeted
costs. Accordingly, an imbalance situation exists between the two overhead accountsIf Overhead Control > Overhead Allocated, this
is called Underallocated OverheadIf Overhead Control < Overhead Allocated, this
is called Overallocated Overhead
![Page 26: Chapter 04final](https://reader033.fdocuments.in/reader033/viewer/2022060109/555880b3d8b42aad358b496b/html5/thumbnails/26.jpg)

Accounting for OverheadThis 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 Over/Underapplied OverheadAdjusted 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
