BASIC CONCEPTS OF COST ACCOUNTING
Overview
According to Chartered Institute of Management Accountants ICIMA), cost is any amount
of expenditure incurred on or attributable to a specified thing or activity. This cost maybe
related to rendering services for a revenue, acquiring goods or services for resale,
manufacturing of products for delivery to ultimate consumers. These costs may be
grouped accordingly to their common characteristics.

Difference between Cost Accounting & Financial Accounting
COST ACCOUNTING
FINANCIAL ACCOUNTING
AS TO NATURE
It relates to the different costing methods It relates to the classifying, recording and
and techniques in accumulating the cost of analyzing of business transactions and
a product, process, project or service and events, the end product of which are

such as financial institutions, creditors,
suppliers and
government regulatory
bodies.
AS TO OBJECTIVE
The main objective is to determine the cost Its objective is to reflect the correct
to produce a unit, process or project or cost financial picture/information of the entity to
to deliver a service. The actual costs the different stakeholders.
incurred is usually compared with
estimates or budgeted costs to guide the
management in making relevant decisions.
AS TO REPORTS/FINANCIAL STATEMENTS
The reports required by management are The basic financial statements as the end
the Cost of Production Report and product of financial accounting are (1)
Statement of Cost of Goods Manufactured Statement of Financial Position or Balance
and Sold. The Cost of Production Report Sheet, (2) Statement of Comprehensive
summarizes the total costs incurred in Income or simply Income Statement, (3)
production like the direct materials, direct Statement of Changes in Equity, and (4)
costs and overhead. There is no standard Statement of Cash Flows.
The
format in presenting the cost information
accountants are guided by International
Financial Reporting Standards in the
preparation of financial reports.
CLASSIFICATION OF COSTS
1. By nature of expenses
1.1 Material costs
1.2 Labor costs (Employee)
1.3 Expenses
2. By nature of traceability to a cost object
2.1 Direct costs
2.2 Indirect costs
3. By function
3.1 Production/Project costs.
The elements of product costs in a manufacturing business are the following:
1. Materials. Materials include the raw materials and other factory
supplies used in manufacturing operation. They are classified as:
(a) Direct Materials.
(b) Indirect materials
2. Labor. Labor represents the compensation and other benefits paid
to the workers in the factory. They are classified as:
a) Direct labor
b) Indirect labor
Prime costs
is the sum of direct materials and direct labor.
3
Module 1 Cost Accounting Concepts & Classification
3. Manufacturing overhead. Manufacturing overhead is an indirect
product cost and it includes productions costs other than direct
materials and direct labor. They include:
Conversion costs =
Overhead
Direct labor + Manufacturing
3.2 General & Administrative costs
3.3 Selling/marketing/distribution costs
4. By nature of production or operation process
4.1 Joint costs
These are costs incurred in a single process that yields two or more products.
They are production costs (direct materials, direct labor and factory overhead)
incurred up to the point where products are separately identified. Example of joint
costs: Cost of dough, labor of baker, and overhead incurred by a bakeshop.
4.2 Contract costs
Cost of a contract agreed upon between the contractee and the contractor.
4.3 Batch costs
Batch Cost shall be the aggregate cost related to a cost unit which consist of a
group of similar articles or services which maintain its identity throughout one
or more stages of production or operation.
4.4 Operation costs
Operation Cost shall be the cost a specific operation involved in production of
goods or rendering of services.
4.5 Process costs
Process cost shall be the cost of production or operation process where goods
are produced or services rendered from a sequence of continuous or repetitive
operations or processes during a period.
5. For Decision making purposes
5.1 Controllable costs
Controllable costs are costs that are primarily subject to the influence of a given
responsibility center manager for a given period of time. Examples are:
5.2 Non-controllable costs
These are costs that cannot be controlled or influenced by a responsibility
center manager. Examples are: Cost of renting equipment
4
Module 1 Cost Accounting Concepts & Classification
5.3 Opportunity costs
These are benefits foregone because one course of action is chosen over
another, expressed in other words, these are future cash inflow that will be
sacrificed as a result of a particular management decision. Examples are
5.4 Sunk costs or past costs
These are costs that have already been incurred in the past and will not be
changed or avoided by any decision in the future. It is not relevant in decision
making. Examples are:
5.5 Relevant cost.
This refers to costs that change with each decision that a company makes. It
includes incremental, opportunity and avoidable costs. Examples are: Future
cash flows, avoidable costs,
5.6 Incremental costs.
Where different alternatives are being considered, relevant cost is the
incremental or differential cost between the various alternatives being
considered.
5.7 Period Cost
Period costs are operating expenses that are associated with time
periods, rather than with the production of goods and services.
Period costs are charged directly to expense accounts on the
assumption that their benefit is recognized entirely in the period when
the cost is incurred.
They are non-manufacturing costs and non
inventoriable costs. They include:
a) Marketing and Selling Costs.
b) Distribution costs.
c) Administrative Costs.
5.8 Product cost
The product costs include costs of direct materials, direct labor and factory
overhead.
5.9 Avoidable
Avoidable costs are those costs that are avoided by making one choice over
another.
5
Module 1 Cost Accounting Concepts & Classification
5.10
Unavoidable costs
These are the costs not change in the future when a manager makes one
decision versus another. They are costs that will continue to happen.
6. By nature of behavior
6.1 Fixed costs
These are costs that are constant in total within the relevant range of activity
but variable on a per unit basis. These costs do not change as activity
changes. As the activity level increases or decreases, total fixed cost
remains constant but unit cost declines or goes up.
6.2 Variable costs
These are costs that vary in total in direct proportion to changes in the volume of
production. Variable cost is constant amount on a per unit basis as activity
changes within a relevant range. As activity changes, total variable costs
increases or decreases proportionately with the activity change, but unit variable
costs remain the same.
6.3 Mixed costs
These are costs that contain fixed and variable cost.
7. According to time
7.1 Historical costs are actual costs incurred in the past.
7.2 Pre-determined costs are estimated costs.
8. According to planning and control
8.1 Budgeted costs are expected costs to acquire goods or services or to
manufacture products
8.2 Standard costs are predetermined cost of materials, labor and overhead to
product a unit of product.
HIGH-LOW METHOD OF SEPARATING MIXED COSTS
When cost is classified as mixed, it is appropriate to separate the fixed cost from
the variable cost. Variable cost per unit is completed as:
Cost at high level cost at lowest level (within relevant range)
Highest activity lowest activity
Or:
Change in total costs / Change in activity level = VC per unit
6
Module 1 Cost Accounting Concepts & Classification
Procedures:
1. Select the highest and lowest levels of activity and costs (within relevant
range)
2. Compute the variable cost element
3. Compute the variable cost at the highest and lowest level of activity.
4. Determine the fixed cost at each level of activity.
3 Inventory Accounts in a manufacturing business
1. Finished Goods inventory. Goods ready for sale
2. Work in Process inventory. Unfinished jobs at the end of a period
3. Raw Materials inventory. Unused raw materials at the end of a period
Inventory Systems
1. Perpetual inventory systems. It requires stock card to record the in and out of
inventory. The movement of inventory is recorded in the inventory account
itself.
2. Periodic inventory systems. No stock card is required but a mandatory
physical counting is done at the end of the period.

ELEMENTS OF PRODUCT COSTS
Overview
There are three elements of manufacturing costs, and these are the materials, labor and
manufacturing overhead. The flow of costs is generally the same for all costing system.
Module Objectives
Differentiate perpetual inventory and periodic inventory system of handling
inventories
Journalize transactions related to raw materials: purchases, returns to suppliers
and freight under perpetual and periodic inventory system
Differentiate FIFO and average method of inventory valuation
Calculate cost of goods sold under Just in Time (JIT) using back flush
accounting
Know the different types of labor remuneration
Differentiate direct from indirect labor
Compute the correct deductions from payroll like absences,
tardiness, SSS, WHT, Philhealth, and Pag-ibig
Prepare factory payroll
Distribute factory payroll to proper accounts
Journalize factory payroll
Journalize incurrence of various manufacturing overhead
Compute predetermined overhead rate using plant wide rate and departmental
overhead rate
Apply traditional method of allocating overhead
Dispose overhead variance using two assumptions: (a) overhead variance is
immaterial and (b) overhead variance is material
Allocate service costs using direct method, step method and reciprocal method.
Course Materials
The elements of product costs are materials, labor and overhead.
Materials
These are materials used for the purpose of manufacturing a product or
rendering of a service. These are recorded in the books net of trade discounts,
rebates, taxes and duties refundable that can be quantified with reasonable
accuracy. This may include raw materials, factory supplies, cost of packaging
materials, spare parts, and many more.

Inventory Stock Card
The stock card is used to record the movement of the inventory. The beginning
balance is entered first under balance column. Entries in this stock card are made
in chronological order (according to date of occurrence). After proper posting has
been made on purchases and issuances, the stock card shows the balance of the
inventory in units and in peso values at a given period.

Inventory Valuation Methods
The most common methods of valuing raw materials are:
a. FIFO (first in, first out)
b. Simple Average
c. Weighted Average
FIFO. Under FIFO method, raw materials inventory is reported at latest cost while the
Cost of Goods Sold is reported at earliest cost. In a period of rising prices, this method
will yield a higher gross profit because the cost of goods sold is assigned lower cost.
Average Method. Under the simple average method, the total unit cost is divided by the
total items to arrive at the simple average unit cost. This procedure is repeated every time
Module 2. Elements of Product Costs
13
raw materials are acquired. Under weighted average method, divide the total costs of raw
materials available by the number of units to arrive at the weighted average per unit.
Example:
Below are transactions regarding Raw Material A of Masagana Company:

Scrap materials
Scrap materials are defective materials or leftover materials in production. Scrap
includes fillings or excessive trimmings of materials after the manufacturing operations;
defective materials not suitable for manufacturing operations; and broken parts of
materials as a result of employee error or machine breakdown that causes the product in
a poor quality condition. If these materials can be traced to a specific job, the market
value of the scrap materials is debited to Scrap Materials and credited to Work in
Process. If the scrap recovered cannot be traced to a specific job, the market value is
credited to Miscellaneous Revenue instead of Work in Process.
Methods of accounting for scrap materials
1.
2.
3.
4.
Reduction of the cost of specific products which were produced
Reduction of the cost of production in general
Recognizing as other revenue for the market value of the scrap
Recognizing as sales revenue for the market value of the scrap
Backflush Accounting
In a traditional normal costing or standard costing, journal entries are required in the same
order from purchase of raw materials, production, completion and sale of the goods. An
alternative approach to this system is the backflush accounting which omits some of the
journal entries relating to the stages from purchasing of raw materials to sale of the goods.
In a JIT system, when materials are purchased, Raw and in Process Inventory account is
Module 2. Elements of Product Costs
15
maintained which includes only the raw materials purchased. Conversion costs incurred
(labor and overhead) are summarized in a Conversion Costs Control account. The
conversion cost is then charged immediately to cost of sales. In backflush accounting,
there is no work in process or materials inventory accounts.
Illustration.
Conversion cost is charged immediately to cost of sales account.

Factory Labor
Factory labor represents the wages of workers in the factory, both direct and
indirect laborers. It includes the regular basic pay; cost of living allowances, 13th month,
and overtime pay excluding premium. Overtime premium is the wage rate paid to workers
for both direct and indirect laborers in excess of their regular wage rate and is usually
considered as part of indirect labor costs. Other items composing labor costs are
in-house laborers, performance bonuses, hospitalization and educational benefits,
share in SSS, Philhealth and pag-ibig, vacation and sick leave pay, pension
costs, and salaries paid to factory workers during their Idle time (time when no orders are
received or when machines are broken down). These types of labor compensation are
classified as indirect labor costs.
The factory payroll is supported by time card, showing the time in and time out of
every factory worker. This is the basis of the payroll department in preparing the payroll.
Since a worker maybe working on different jobs, a time ticket is to be prepared by each
worker showing the particular job he works during the day. This is also the basis of
distributing the payroll.
For the updated table for WHT, SSS, Pag-ibig and Philhealth deductions, please
refer to the website cited below. Read also the latest provisions of PD 442, Labor Code
of the Philippines.

Factory Overhead
Factory or manufacturing overhead is an indirect product cost and it includes
productions costs other than direct materials and direct labor. They include:
(a) Factory supplies such as oil and other cleaning materials used in the factory.
(b) Wages of supervisors, factory maintenance personnel, raw materials
handlers and security officers stationed in the factory premises.
(c) Depreciation of factory plant and equipment

Maintenance and repairs on factory plant and equipment
Power, light and water
Telephone and mailing costs
Cost of regulatory compliance such as meeting factory safety requirements
and disposal of waste materials.
(i) Idle time by factory workers due to machine breakdowns or new set ups which
are unavoidable in production process. During their idle time, the workers are
not productive therefore the cost is spread over the entire production not to a
specific product.
Traditional Method Of Allocating Factory/Manufacturing Overhead
Based on direct labor hours or direct labor cost
Example: A manufacturing company produce two products, product 1 and product
2. The following cost information relate to the production of the two products.

Departmental Rate And Plantwide Rate
Departmental rate. One overhead rate per department, so that if there are two or
more processing departments, two or more OH rates are used to apply overhead
to production.
Plant-wide rate. If only one overhead rate is chosen by a company for the allocation
of manufacturing overhead to different jobs, that overhead rate is called plant wide
rate.
Illustration:
Sunflower Manufacturing Company has two producing departments, Assembly and
Finishing Department. Assembly Department has significant amount of labor related
overhead and it uses direct labor hours as the cost driver while Finishing Department
has significant amount of machine-related overhead and it uses machine hours as
the cost driver.

Allocation Of Service Department Costs
Service department costs are costs of departments other than producing
departments like maintenance, human resource, canteen and others.
Module 2. Elements of Product Costs
22
Methods of Allocating Service Costs to the different producing departments
Direct method allocates service costs directly to production department only
and does not consider services provided
Step method or sequential allocation method allocates service costs step by
step. The service departments are first ranked according to the amount of service
rendered and received. .
Algebraic or simultaneous or reciprocal method.
Illustration: Direct method, Step method and Algebraic method of allocating
service department costs.
Mahogany Manufacturing Company has four departments. Two producing
departments, Assembly and Finishing, and two service departments, Cafeteria and
Maintenance. The overhead cost of Cafeteria is allocated based on number of
employees while the overhead cost of Maintenance is allocated based on estimated
factory overhead. Assembly department used direct labor hours and finishing
department used machine hours as bases in computing for predetermined
overhead rates.

Cost Accounting cycle in job order costing system
The job order costing system is used when various jobs are produced that are different
from each other and each job has a significant cost. To illustrate the accounting for job
order costing system, assume the following:
At the beginning of the year, Primer Manufacturing Company had the following balances
in its inventory accounts:
Raw materials
Work in process

Job Order Costing System
PRODUCTION LOSSES IN JOB ORDER
In the process of production, some goods may be defective which require
additional reworking to make them good units and some may be spoiled. Spoiled units
cannot be reworked but they can be disposed of a very minimal market value
Spoilage is normally anticipated to occur
Spoilage maybe normally anticipated to occur in the production. In this situation,
manufacturing companies include an allowance for spoilage in the computation of predetermined overhead rate. The pro-forma entry to record the discovery of spoilage is:
Spoiled goods (MV of spoiled units)
Manufacturing overhead (unrecovered
costs)
Finished goods (good units)
Work in process
000
000
000
000
If production results to defective work, the entry would be:
Manufacturing overhead (cost of rework)
Raw materials
Accrued wages
Manufacturing overhead (applied)
000
000
000
000
Spoilage specifically identified with a particular job
If spoilage and defects are occasionally experienced in production process, then
the allowance for spoilage should not be included in the computation of
predetermined overhead rate.
Illustration: Belro Company accepted a job for 1,000 pieces of computer bags.
The manufacturing cost per unit of computer bag is as follows: Materials, P300;
direct labor (2.0 hours at P48.00 per hour), P96.00 plus overhead. At inspection,
50 pieces are spoiled which can be sold at P200 per piece.

Sometimes, a customer may change the specifications of a job order causing for
during the process, the customer will shoulder the cost of reworking in case of
defective jobs, or shoulder the lost in case of spoilage. Using the same problem

The market value of the spoiled goods is debited to Spoiled Goods Inventory account
while the unrecovered cost of the spoiled units remains with the job, and it is absorbed by
the customer.
If such action of the customer results to a defective work, the customer is charged
with the cost of reworking. The cost of rework is then charged to work in process
account. Assume that the cost to rework the 50 units follows:

Process Costing
Overview
In a process costing system, the cost of production is accumulated by departments or
processes. The output of one department is the input of the next processing
department. The products produced under process costing are in large volumes and
the manufacturing costs incurred are accounted by departments rather than specific
product as in job order. Examples of manufacturing companies that uses process
costing are San Miguel Corporations, Coca-Cola Bottling Company, Philippine Refining
Company and many more.
Module Objectives
After thorough discussion of the topics, the learner will be able to:
Described the flow of costs in a process costing system
Explain how equivalent units of production (EUP) is calculated under average and
FIFO method
Prepare journal entries to record the flow of costs in process costing systems with
sequential production departments
Prepare cost of production report even and uneven application of cost, first and
then subsequent process or department, with and without loss units both normal
and abnormal

Distinction between Job Order and Process Costing
In many ways, job order and process costing are similar. The same accounts are used in
summarizing the cost of production and both have the same objective, to assign costs to
the units produced.
Below are distinct characteristics of job order and process costing:

THE CONVERSION PROCESS
Either actual or normal costing system may be used in process costing. The flow of costs
in job order and process costing are similar. All raw materials are debited to Raw materials
Inventory when purchased, when issued, it is debited to Work in Process. Materials may
be issued to production at different stages. It may be added at the beginning of the
process, during the process or at the end of the process. In process cost system, fewer
requisitions are generally required than in job order cost system, because the materials
are used for processes rather than for specific jobs.
For labor, time tickets are used in determining the cost of labor assignable to the
production department while manufacturing overhead incurred is recorded also in the
same manner as in job order.
When materials are processed in two or more departments before they become finished
products the costs transferred from a prior department are called Transferred in Costs.
These transferred in costs are treated as raw material costs in the viewpoint of the
receiving department. The following entry is made to record the cost transferred in to the
department.
Work in Process (receiving dept.)
Work in Process (previous dept.)
000
000
In addition to the transferred in costs, the receiving department may incur additional
materials, labor and overhead and they are recorded in the same manner as in the
previous department.
First In First Out (FIFO) And Weighted Average Method
There are two methods used to determine the flow of costs to the work in process
inventory account, the FIFO and Weighted Average methods. The FIFO method assumes
that units in the beginning inventory are completed first, before any units are started in the
process resulting to the accounting of units in the beginning inventory separate from the
newly started units. The Weighted average method averages the cost of units in the
beginning inventory with the cost of units that were started during the period. The cost of
production report is the key document used in a process cost system. This report also
gives the accountant information on what to record in the books.
43
Module 4
Process Costing System
The five (5) steps to be followed in the preparation of a Cost of Production Report are:
Step 1. Calculate the total units to account
Prepare a quantity schedule (the physical flow of units) to determine the total units
to be accounted for. These units are then accounted by the output of the period, which
consists of units transferred out, units in process at the end of the period and units spoiled
or lost during the process
Step 2. Compute the equivalent units of production
Equivalent units of production are an approximation of the number of whole units of output
that could have been produced during the period. EUPs are calculated by multiplying the
number of actual but incomplete units produced by the degree of completion or work done
during the period.
It measures the work done during a period, expressed in fully
completed units.
Weighted Average method is used to determine an average cost per unit of inventory.
The number of units in the beginning inventory together with the manufacturing costs
attached to it is merged with the current period output and manufacturing costs.
FIFO Method:
The beginning inventory is accounted separate from the current
production. This method assumes that units in beginning work in process are completed
first, before any new units are started. Thus, the completed & transferred has two
categories:
1. Work in process beginning completed during the period, and
2. Units just started and completed during the period
In computing for the equivalent units of production, the work done on beginning inventory
in the prior period is kept separate from the work done in the current period.
Step 3. Find the total costs to account
The total costs to account include the balance of Work in Process at the beginning plus
all current costs added during the period.
Step 4. Compute the unit cost per EUP
Unit production costs are costs expressed in terms of equivalent units of production. When
equivalent units of production (EUP) are different each in each cost element, then three
unit costs must be computed for Materials, Labor and Overhead.
WA: IP beg. Cost + Added Costs / EUP
FIFO: Added Costs during the period/EUP

Assign the total production costs to units completed and in process at the end of a period
by multiplying the EUP per cost element by the UC per cost element.

Illustration. Cost of Production Report
2 departments
A Cost of Production Report is a mandatory reportorial requirement of a manufacturing
company. This report should contain heading which comprise of (1) Name of the
Company, (2) Title of the Report, and (3) Date covered by the report.
To illustrate, assume the following:
In the Forming Department, materials are added when the process is 20% complete while
in the Finishing Department is added when the process is 80% complete.
Work in
process on Jan. 1 is 40% converted in the Forming and 60% converted in the Finishing
Department. Work in process on June 30 is 25% converted in the Forming Dept. and
30% converted in the Finishing Dept. Conversion costs are added evenly throughout the
process.

STANDARD COSTING IN PROCESS COST
Manufacturing companies normally sets standard cost once a production process
is established, making it possible to determine the cost of activity at the start of the period.
The equivalent units of production are determined in the same manner as in FIFO method
of costing. The only difference is, unit cost is no longer computed for each element
because the standard unit cost is used.
Pro-forma entries under standard costing:
(1) Issuance of materials:
Work in process

LOST/SPOILED UNITS
Continuous Loss
The input in a manufacturing process may result to a lower output due to evaporation or
shrinkage, which are inherent in the production process. The costs of normal loss due to
shrinkage or evaporation are accounted using the method of neglect. The decrease in

Module 4
Process Costing System
the units resulting to loss or spoilage is not included in EUP computation. The effect of
this method increases the cost per EUP.
Discrete Loss
Discrete loss is assumed to occur at a specific point, normally when quality check is made
at inspection point. Some production losses may be due to errors in the production
process thus resulting to units that are rejected for failure to meet quality standards. These
spoiled units are included in EUP computation because the percentage of work done on
these units can be clearly identified. The accounting for the cost of the spoiled units
depends on whether the loss is considered normal or abnormal.
How do lost units affect the equivalent units of production?

After thorough discussion of the topics, the learner will be able to:

NATURE OF JOINT PROCESS
Joint processes are production processes in which the creation of one product also creates other
products. It is a process in which one input yields multiple outputs. Joint production processes are
common in the food manufacturing industry like San Miguel Foods Corporation, personal beauty
& wellness industry like Palmolive Philippines, Inc. and many more.
METHODS OF ALLOCATING JOINT COSTS
from joint processing costs is inseparable from that of every other product. When produced
simultaneously, joint products and by-products do not have traceable, individual costs. Therefore,
the allocation of joint production costs is necessary. The common methods of allocating joint
costs are:
A. Physical measure
Average unit cost (based on units produced)
Weighted average method (based on weight factors)
B. Market Value method
Sales value method (Sales value at split-off point)
Net realizable value method (at split off point).
Net Realizable Value of the product is equal to:
54
Module 5
Accounting for Joint Products & By-Products
Final sales value less separable costs and
Costs necessary to dispose of the products such as distribution and selling
costs.
Hypothetical market value method or Approximated Net Realizable value method
C. Constant Margin Approach
This method yields the same gross profit rate for all the products. The procedures in
allocating joint costs using this method follow:
1. Compute the overall gross margin percentage:
Total sales (all products)
Less: Total costs (joint costs + separable costs)
Gross margin
Gross margin rate = gross margin / total sales
2. Determine the cost of a product:

In joint process, the total costs to manufacture a product comprise of:
Allocated joint costs + additional processing costs
SELL OR PROCESS FURTHER
The decision to incur additional costs for further processing should be based on the
incremental operating income attainable beyond the split-off point. The incremental operating
income or differential income is the difference between incremental sales revenue and
incremental costs or additional processing costs. If incremental revenue or differential revenue
is greater than incremental costs, process further the products.
55
Module 5
Accounting for Joint Products & By-Products
Incremental Sales = Final Sales
Ssales at split off
Incremental income = Incremental Sales Incremental cots
METHODS OF ACCOUNTING BY PRODUCTS
The common practice is to make no allocation of the joint processing costs to the byproducts, the secondary products with very minimal value. By-products are accounted in the
books in either of the two methods:
(1) Net realizable value method. This method requires that a by-product inventory
account is used to summarize the sales value of the by-product minus all costs related
to processing, storing and disposing. The net realizable value then is used to reduce
the joint costs of the main products, thus, work in process inventory is credited. If the
by-product is sold, Cash or Accounts Receivable is debited and by-product is credited.
In cases where the costs related to processing, storing and disposing is greater than
the sales value of the by-product, any loss is added to the cost of the main products.
(2) Realizable value method. This method recognizes the value of the by-product only
when they are sold. The sales value of the by-product less related costs to process
and to dispose is presented as (1) sales revenue by product; (2) as other income;
(3) as a reduction from cost of goods sold; and (4) as reduction from cost of goods
manufactured.

and Lucky Her (large noodles) from common inputs, flour and spices. A waste product results
from the joint process which is sold to cattle ranchers at P10 per ton. The revenue from the sale
of by-product is treated as other sales revenue. At split off point, the main products can be sold
to companies who package and sell them under their own branch names. With the rising
popularity of noodles as a meal, Lucky Company add bits of preprocessed vegetables to Lucky
Him and Lucky Her, package them, and sell them under the brand names Nissins and Ramens.

DEFINITION AND OBJECTIVES OF STANDARD COSTING
Standards function
In businesses,
managers set an acceptable level of performance for every aspect of operation, especially
in the provision of products and services. At the end of each period, managers would want
to know how the actual results fared against the standards set, and whether corrective
actions are necessary. A reasonably prudent management will strive to ensure that overall
product quality is high while keeping costs under control. To do this, management needs
a mechanism to generate actual cost and standard cost reports and to analyze the
deviations from the expected results (standards).
Standard costing is a system of setting standard costs, accumulating and summarizing
actual costs, and highlighting deviations from the pre-determined standard costs, or
variances. Although standard costing is applicable for both manufacturing and service
enterprises, our discussions will focus on its application in manufacturing environment.
Standard costing can also be used in conjunction with either job order or process costing
accumulation systems.
When a standard costing system is in use, it does not mean that there is no need for actual
costs. Actual costs should likewise be recorded and accumulated and should be made
available for comparison with the standard costs to determine deviations.
Standard cost is defined as a pre-determined unit cost of a product or service for the
purposes of cost control. Standards are set for all cost components direct materials,
direct labor, and factory overhead.
Variances are the deviation of actual costs from the budgeted (standard) costs for each
cost component direct materials, direct labor, and factory overhead. These variances
are monetary amounts and are reported as either favorable (when the actual costs are

Module 6
Standard Costing
USES AND LIMITATIONS OF STANDARD COSTING
Standard costing has the following objectives:
simplify bookkeeping and reduce clerical costs;
facilitate management planning;
instilling a culture of cost-consciousness among the employees
contribute to management control by providing basis for evaluation and cost
control; and
highlight variances in line with management by exception principle.
Management by exception a practice of focusing management attention on areas that
are not operating as expected.
Standard costing has the following limitations:
standard costs are mainly based on estimates and when cost components
fluctuate wildly during the period, there is a need to revise standard costs
previously set;
setting up standard costs in certain industries may be overly complex, especially
when it involves multiple products requiring different raw materials, time-motion
studies, multiple stages of manufacturing, etc.;
the standards set must be challenging enough to control costs yet should also be
attainable; extremely rigid standards that are very difficult, if not impossible to
attain may cause demotivation among employees and they may even resort to
extremely lax standards that are
very easy to attain will not achieve the purpose of controlling costs;
fixing responsibilities among managers who own variances is difficult and may be
highly political.
DETERMINATION AND SETTING UP OF STANDARDS
In small organizations, the top management may be directly involved in setting up the
standards. However, in larger organizations, the responsibility of setting up costs is
delegated to cross-functional teams within the organization.
The following are the two standards used:
Quantity standards specify how much of an input should be used for each unit of
product or service; and
Cost (price) standards specify how much should each unit of product or service
cost.
The standard cost for each cost element is equal to Quantity standard multiplied by the
Cost standard.
59
Module 6
Standard Costing
Material standards may be jointly formulated by the product engineers and the plant
manager (quantity) and the purchasing and accounting departments (cost).
Labor standards may be jointly formulated by the product engineers and the plant
manager (time) and the HR and accounting departments (rate).
Overhead standards may be jointly formulated by the plant managers (activity) and the
accounting department (rate).
VARIANCE ANALYSIS & DISPOSITION VARIANCES USING 2-WAY VARIANCE
METHOD
Accounting for Materials
Materials Purchase Variance
Upon purchase, the raw materials are recorded at standard cost. There are no
complications when the material is purchased at standard cost. When there is a difference
between the actual cost and the standard cost, the difference is accounted for as a
variance. The variances are calculated and isolated at the time of purchase.
Illustrative example:
Suppose that the standard cost of raw material is P100/kg. The company purchased 1,000
kilograms of the said raw material under the following assumptions:
a. When the actual cost per kilogram is P98 (Favorable variance).

Standard Costing
Materials Usage Variance
Upon issuance to production, raw materials are recorded at standard cost based on the
standard quantity. The difference between the actual quantity issued to production and
the budgeted quantity is accounted for as a variance.
Illustrative example:
Suppose that a material has a standard cost of P100/kg. and one batch of a certain product
requires 500 kgs. of the said material. The accounting for issuance of material to
production follows:
a. When 495 kgs. is issued to production (Favorable variance)

Work-in-process inventory (at std. qty x std. cost)
Raw Materials (at actual qty. x std. cost)

Accounting for Labor
Direct labor hours rendered are recorded at standard hours allowed for the output x
standard rate. Any difference between the actual rate and the standard rate is recorded
as direct labor rate variance. Any difference between the actual hours rendered and
standard hours allowed for the output is recorded as direct labor efficiency variance.
Direct labor rate variance is computed as the difference between the actual labor rate and
the standard labor rate, multiplied by the actual hours rendered.
Direct labor efficiency variance is computed as the difference between the actual hours
rendered and the standard labor hours allowed for the output, multiplied by the standard
labor rate.
Illustrative example:
Suppose that the standard direct labor rate is P5/hour and the standard direct labor hours
to produce a single unit of product is 2 hours.

Accounting for Overhead
In developing overhead application rates, a company must specify an operating level or
capacity. Remember that rates are computed by dividing the budgeted overhead costs by
the production capacity. Measures of capacity could be theoretical, practical, normal, or
expected.
Theoretical capacity or ideal capacity is based on optimum level of performance
based on all factors operating perfectly. It disregards realities such as machine
breakdowns, holidays, and idle time.
Practical capacity is the level of production that can be achieved during regular
working hours, with allowance for machine breakdowns, holidays, and idle time.
Normal capacity is the average level of production over the long run.
Expected capacity is the anticipated level of production for the next period.
Firms usually use normal or expected capacity in planning for overhead costs. Usually,
firms compute overhead rates separately for fixed and variable costs.
To aid managers in computing overhead rates, a flexible budget is prepared. It presents
expected overhead costs based on cost behavior (fixed or variable) at different activity
levels. Fixed overhead costs remain constant within the relevant range of activity while
variable overhead costs change in relation to changes in the level of activity. For planning
purposes, capacity is stated as a single level of activity.
The following are the overhead variances analyzed in a standard costing system.
Budget variance is the difference between the actual overhead costs incurred
during the period and the budgeted overhead costs based on the flexible budget.
This variance is a measure of how well managers control costs and hence, is also

Standard Costing
called controllable variance. Causes of budget variances are attributable to the
monetary amount spent (spending) and the efficiency of the operations (efficiency).
Thus, budget variance could be further analyzed into spending and efficiency
variances, but for the purpose of discussion, we will be analyzing total budget
variance only.
Volume variance is the difference between the total budgeted overhead and the
overhead applied to production. Alternatively, it could be expressed as the
difference between the denominator level of activity and the standard hours
allowed for the output of the period, multiplied by the fixed portion of the
predetermined overhead rate. This variance is a measure of capacity utilization
so
called noncontrollable variance.
