CHAPTER 1
BASIC COST CONCEPTS
1. BASICS
1. Define the term “Cost”.
1) Meaning of Cost:
(a) Cost refers to the expenditure incurred in producing a product or in rendering a
service.
(b) Cost is a measurement, in monetary terms, of the amount of resources used for the
purpose of production of goods or rendering services.
(c) Cost is expressed from the producer or manufacturer’s viewpoint, (i.e. not that of
consumer / end user).
(d) Cost ascertainment is based on uniform principles and techniques.
2. Define the terms “Costing”, “Cost Accounting” and “Cost Accountancy”.
1) Costing: The technique and process of ascertaining costs.
2) Cost Accounting: The process of accounting for cost which begins with recording of
income and expenditure or the bases on which they are calculated and ends with the
preparation of periodical statements and reports for ascertaining and controlling costs.
3) Cost Accountancy: The application of costing and cost accounting principles, methods
and techniques to the science, art and practice of cost control and the ascertainment of
profitability. It includes the presentation of information derived there from for the
purpose of managerial decision-making.
3. List the objectives of Cost Accounting
The primary objective of study of cost is to contribute to profitability through Cost Control
and Cost Reduction. The following objectives of Cost Accounting can be identified –
1) Ascertainment of Cost: This involves collection of cost information, by recording them
under suitable heads or account, and reporting such information on a periodical basis.
2) Determination of Selling Price: Selling Prices are influenced by internal and external
factors. However, generally, prices cannot be fixed below cost. Hence, Cost Accounting
is required for determination of appropriate Selling Prices.
3) Ascertaining the profit of each activity: Profit of each department / activity / product
can be determined by comparing its revenue with appropriate cost. So, Cost Accounting
ensures profit measurement on an objective basis.
4) Assisting Management in decision – making: Business decisions are taken after
analyzing cost and benefits of each option, and the Manager chooses the least cost option.
Thus, Cost Accounting and reporting system assists Managers in their decision – making
process.
5) Cost Control and Cost Reduction: In the long run, higher profits can be achieved only
through Cost Control and Cost Reduction. Cost Accounting seeks to ensure profit by
providing support for cost control / reduction decisions.
4. Distinguish between Cost Reduction and Cost Control.
Particulars Cost Reduction Cost Control
1. Permanence Permanent, Real and genuine savings
in cost.
Could be a temporary saving
also.
2. Saving Focus Saving in Cost per unit. Saving either in Total Cost
or Cost per unit.
3. Product
Quality
Product’s Utility, Quality &
Characteristics are retained.
Quality Maintenance is not a
guarantee.
Abhimanyyu Agarrwal Jai Mata Di
9874311319 Page 2
4. Performance
Evaluation
It is not concerned with maintenance
of performance according to
standards.
The process involves setting
up a target, investigating
variances and taking
remedial measures to correct
them.
5. Nature of
Standards
Continuous process of critical
examination includes analysis and
challenge of standards.
Control is achieved through
compliance with standards.
Standards by themselves are
not examined.
6. Dynamism Fully dynamic approach. Less dynamic than Cost
Reduction.
7. Coverage Universally applicable to all areas of
business. Does not depend upon
standards, though target amounts may
be set.
Limited applicability to
those items of cost for which
standards can set.
8. Nature of
Costs
Emphasis here is partly on present
costs and largely on future costs.
Emphasis on present and
past behavior of costs.
9. Analysis To find out substitute ways and new
means.
Competitive analysis of
actual results with
established norms.
10. Nature of
Function
(a)Value Engineering, (b)
Standardization and Simplication, (c)
Work Study, (d) Variety Reduction,
(e) Quality Measurement & Research,
(f) Operations Research, (g) Market
Research, (h) Job Evaluation and
Merit Rating, (i) Improvement in
Product Design, (j) Mechanisation and
Automation, etc.
Budgetary Control and
Standard Costing.
5. Compare Cost Accounting with Financial Accounting. Does Cost Accounting
supplement Financial Accounting? Discuss.
The broad areas of difference between Financial and Cost Accounting are –
Particulars Financial Accounting Cost Accounting
1. Users of
Information
Financial Statements are used by
Internal management and also
outside parties like Government,
Creditors, Customers, Employees,
etc.
Detailed cost information is
presented to internal management
for proper planning, decision –
making and cost control.
2. Statutory
Compliance
Requirements of Statutes like
Companies Act, Income Tax Act,
etc. are met through Financial
Accounting.
Generally Cost Accounting is
voluntary, except in cases where
Cost Accounting Records Rules
mandatorily apply to the
enterprise.
3. Nature /
Objectivity
Transactions are recorded in a
subjective manner. Accounting
Policies may differ from one Firm
to another Firm.
Expenditure is recorded in an
objective manner. Costing
principles and techniques are
generally uniform to all Firms.
4. Focus Focus of accounting is on recording
the transactions.
Focus of accounting is to control
cost.
5. Nature of
Cost
Generally Historical Costs are used
for recording purposes. Projected
Financial Statements may also be
drawn for budgeting purposes.
It considers both historical costs
and predetermined, i.e. Standard
Costs. It also extends to plans and
policies to improve future
Abhimanyyu Agarrwal Jai Mata Di
9874311319 Page 3
performance.
6. Stock
Valuation
Stocks are valued at Cost or Net
Realisable Value whichever is less.
Stocks are valued generally at
Cost.
7. Cost
Analysis
Cost / Expenditure and Profits are
generally shown as a whole for the
period.
Costs are analysed product – wise,
department – wise, activity – wise,
etc.
8. Time Period Financial Statements are generally
prepared at the end of the financial
period, usually one year, for
reporting purposes.
Cost data and reports are
presented on a continuous basis
for the Cost Period. The cost
period (also called Control Period)
may be shorter than the financial
year.
9. Forecasting
& Planning
Has limited use for forecasting and
planning. Only broad parameters
like GP, NP, ROI, EPS, etc. can be
laid down.
Specific and detailed plan for each
product / activity / sub – level can
be laid down. Hence, more useful
for budgeting.
10. Utility for
decisions
Helps only for future decisions with
respect to product pricing, make or
buy, asset retainment vs
replacement, etc.
Helps Current & future decisions,
e.g. product price reduction and
higher volume in order to earn
target profit, resource re –
allocation, etc.
11. Control and
Assessment
Financial Accounting suffers from
limitations of lack of analysis of
information, and absence of
detailed control and assessment
parameters.
Better tools of control, analysis
and assessment are available,
some examples are Variance
Analysis, Budgetary Control, &
Marginal Costing.
Note: Cost Accounting supplements Financial Accounting for analysis and decision – making
purposes, as described above.

9874311319 Page 4
On the basis of Behaviour / Nature / Variability, Costs are classified as under –
Type and Description Examples
1. Fixed Cost is the cost which does not vary with the change in
the volume of activity in the short – run. These costs are not
affected by temporary fluctuation in activity of an enterprise.
These are also known as Period Costs.
Salaries, Rent, Insurance,
Audit Fees, Depreciation,
etc.
2. Variable Cost is the cost of elements which tends to directly
vary with the volume of activity. Variable Cost has two parts –
(a) Variable Direct Cost, and (b) Variable Indirect Costs.
Variable Indirect Costs are termed as Variable Overhead.
Materials Consumed,
Direct Labour, Sales
Commission, Utilities,
Freight, Packing, etc.
3. Semi Variable Costs contain both fixed and variable
elements. They are partly affected by fluctuation in the level
of activity.
Factory Supervision,
Maintenance, Power,
Telephone, etc.
7. How are Costs classified on the basis of Elements?
On the basis of elements, Costs are classified as under –
Type and Description Explanation
1. Material Cost is the cost of
material of any nature used for
the purpose of production of a
product or a service.
Material Cost includes cost of Procurement,
Freight Inwards, Taxes & Duties, Insurance, etc,
directly attributable to the acquisition.
Trade Discounts, Rebates, Duty Drawbacks,
Refunds on account of MODVAT, CENVAT,
Sales Tax and other similar items are deducted
in determining the costs of material.
2. Labour Cost means the
payment made to the employees,
permanent or temporary, for
their services. (N 01)
Labour Cost includes Salaries and Wages paid
to permanent employees, temporary employees
and also to employees of the contractor.
Salaries & Wages include all Fringe Benefits
like PF Contribution, Gratuity, ESI, Overtime,
Incentives, Bonus, Ex-Gratia, Leave
Encashment, Wages for Holidays and Idle Time,
etc.
3. Expenses are other than Material
Cost or Labour Cost, which are
involved in an activity.
Expenditure on account of utilities, payment for
bought – out services, job processing charges, etc. can
be termed as Expenses.
8. How are Costs classified on the basis of Relationship?
Based on Relationship, costs are classified into –
Type and Description Components
1. Direct Costs:
Costs which are directly related to / identified with /
allocated to a Cost Centre or a Cost Object, in an
economically feasible way, are called Direct Cost.
Total of all Direct Costs is called Prime Cost.
Direct Material Cost,
Direct Labour Cost, and
Direct Expenses.
2. Indirect Costs:
All Costs other than Direct Costs are called Indirect Costs.
Total of all Indirect Costs is called as Overheads (or
Oncost), since they are generally incurred over various
products (Cost Units), various departments (Cost Centres)
and over various heads of expenditure accounts.
Indirect Material,
Indirect Labour, and
Indirect Expenses.
A summary of Direct and Indirect Costs is given below –
Abhimanyyu Agarrwal Jai Mata Di
9874311319 Page 5
Item and Description Example
1. Direct Material: Costs of Material which can
be directly allocated to a Cost Centre or a Cost
Object in an economically feasible way.
Raw Materials Consumed for production for
a product or service, which are identifiable
in the product or service.
2. Direct Labour: Cost of Wages of workers
who are readily identified or linked with a
Cost Centre or Cost Object.
Wages include all Fringe Benefits like PF
Contribution, Gratuity, ESI, Overtime,
Incentives, Bonus, Ex – Gratia, Leave
Encashment, Wages for holidays and idle
time, etc.
3. Direct Expenses: Expenses other than Direct
Material or Direct Labour, which can be
identified or linked with the Cost Centre or
Cost Object.
Expenses for special moulds used in a
particular Cost Centre, Hire Charges for
tools & equipments for a Cost Centre,
Royalties in connection to a product, Job
Processing Charges, etc.
4. Indirect Material: Cost of Material which
cannot be directly allocable to a particular
Cost Centre or Cost Object.
Consumable Spares and Parts, Lubricants,
etc, i.e. materials which are of small value
and cannot be identified in or allocated to a
product / service.
5. Indirect Labour: Wages of Employees which
are not directly allocable to a particular Cost
Centre.
Salaries of Staff in the Administration and
Accounts Department, Salaries of Security
Staff, etc. (N 01)
6. Indirect Expenses: Expenses other than of
the nature of Material or Labour, and cannot
be directly allocable to a particular Cost
Centres.
Insurance, Taxes and Duties, etc. not being
allocable to a particular Cost Centre.
9. Distinguish between Controllable & Uncontrollable Costs.
One the basis of controllability, Costs are classified into –
1) Controllable Costs: These are costs which can be influenced and controlled by managerial
action.
2) Non – Controllable Costs: These are costs that cannot be influenced and controlled by a
specific member(s) of the organization.
Note: The line of difference between controllable and non – controllable costs is very thin. No
cost is uncontrollable. Controllability is a relative term and is subject to the following factors –
(a) Time: Certain costs are controllable in the long – run and not in the short – run.
(b) Location: Certain costs are not influenced and decided at a particular location / cost centre.
For example, if rent agreements of all factory premises are executed centrally at the Head
Office, Factory Mangers cannot control the incurrence of Rent Cost.
(c) Product / Output: Certain costs are controllable by reference to one product or market
segment and not by reference to the other. For example, some products require more
advertising and sales promotion efforts than other products.
10. How are Costs classified on the basis of Normality?
On the basis of Normality / Expectation, Costs are classified into –
Type Description Treatment
1. Normal
Cost Costs which can be reasonably expected to be
incurred under normal, routine and regular
operating conditions.
Cost that is normally incurred at a given of
output in the conditions in which that level of
output is achieved.
They are included in
the Cost Sheet as
regular cost and used
for decision - making
purpose.
2. Abnormal Costs over and above normal cost, which is not They are not
Abhimanyyu Agarrwal Jai Mata Di
9874311319 Page 6
Cost incurred under normal operating conditions, e.g.
fines and penalties, abnormal wastages, etc.
Unusual or a typical cost whose occurrence is
usually irregular and unexpected and due to some
abnormal situation of production.
considered in the cost
of production for
decision – making,
and are charged to
Profit & Loss A/c.
11. Distinguish between Product Cost and Period Cost.
Why should Product Costs be computed?
On the basis of attributability to the product, Costs are classified as under –
Particulars Product Cost Period Cost (N 08)
1. Meaning These are costs which are assigned to the
product and are included in inventory
valuation. These are also called as
Inventoriable Costs.
These are costs which are not
assigned to the products but
are charged as expenses
against the revenue of the
period in which they are
incurred.
2. Examples Manufacturing Costs, e.g. Cost of Raw
Materials, Direct Wages, Production OH,
Depreciation of Plant, Equipments, etc.
Non – Manufacturing Costs,
e.g. General Administration
Costs, Salesmen Salary,
Depreciation of Office
Assets, etc.
3. Inclusion in
Inventory
Valuation
These are included in inventory valuation.
They are treated as assets till the goods to
which they are assigned are actually sold.
These are not included in
Inventory Valuation. They
are written off as expense in
the period in which they are
incurred.
Note:
Absorption vs Marginal Costing: Under Absorption Costing System, Total
Manufacturing Costs (i.e. Variable and Fixed) are regarded as Product Costs. However,
under Marginal Costing system, only variable Manufacturing Costs are considered as
Product Costs.
Purposes of computing Product Costs are as under –
(a) Preparation of Financial Statements – focus on Inventory Valuation and reporting
profits.
(b) Product Pricing – focus on costs assigned & incurred on the product till it is made
available to customer / user.
(c) Cost – plus – Contracts with Government Agencies – focus is on reimbursement
of costs specifically assigned to the particular job / contract.
12. List the various items of costs on the basis of relevance to decision-making.
On the basis of relevance to decision – making, Costs are classified into (A) Relevant, and (B)
Irrelevant Costs.
(A) Relevant Costs: These are costs which are relevant and useful for decision – making
purposes.
1) Marginal Cost: Marginal Cost is the total Variable Cost, i.e. Prime Cost plus Variable
Overheads. It is assumed that variable Cost varies directly with production whereas Fixed
Cost remains constant irrespective of volume of production. Marginal Cost is relevant for
decision – making, as this cost will be incurred in future for additional units of production.
2) Differential Cost: It is the change in costs due to change in the level of activity or pattern or
method of production. Where the change results in increase in cost it is called Incremental
Cost, whereas if costs are reduced due to decrease of output, the difference is called
Decremental Costs.
Abhimanyyu Agarrwal Jai Mata Di
9874311319 Page 7
3) Opportunity Cost: This refers to the value of sacrifice made or benefit of opportunity
foregone in accepting an alternative course of action. For example, a Firm may finance its
expansion plan by withdrawing money from its bank deposits. Then, interest lost on the Bank
Deposit is the opportunity cost for carrying out the expansion plan. Similarly, if a person quits
his job and enters into business, the salary forgone from employment constitutes opportunity
cost. Opportunity Cost is a relevant cost where alternatives are available. However,
opportunity cost is not recorded in formal accounts and is computed only for decision –
making and analytical purposes.
4) Out – of – pocket Costs: These are costs which entail current or near future outlays of cash
for the decision at hand. Such costs are relevant for decision – making, as these will occur in
near future. This cost concept is a short – run concept and is used in decisions relating to
fixation of selling price in recession, make or buy, etc. Out – of – pocket Costs can be avoided
or saved, if a particular proposal under consideration is not accepted.
5) Replacement Cost: It is the cost at which there could be purchase of an asset or material
identical to that which is being replaced or revalued. It is the cost of replacement at current
market price and is relevant for decision – making.
6) Imputed Costs: These are notional costs appearing in the cost accounts only, e.g. notional
rent charges, interest on capital for which no payment has been made. Where alternative
capital investment projects are being evaluated, it is necessary to consider the imputed interest
on capital before a decision is arrived at, as to which is the most profitable project. These
costs are similar to Opportunity Costs.
(B) Irrelevant Costs: These are costs which are not relevant or useful for decision – making.
1) Sunk Cost: It is a cost which has already been incurred or sunk in the past. It is not relevant
for decision – making. Thus, if a Firm has obsolete stock of materials originally purchased for
Rs.50,000 which can be sold as scrap now for Rs.18,000 or can be utilized in a special job,
the value of stock already available Rs.50,000 is a sunk cost and is not relevant for decision –
making. (N 00, M 03, M 05)
2) Absorbed Fixed Cost: Fixed Costs do not change due to increase or decrease in activity.
Although such Fixed Costs are absorbed in cost of production at a normal rate, they are
irrelevant for managerial decision – making. However, if Fixed Costs are specific, they
become relevant.
3) Committed Cost: It is a cost in respect of which decision has already been taken, and such
decision cannot be altered, e.g. entering into irrevocable agreements for Rent, Technical
Collaboration, etc. Committed Costs are not relevant for decision – making. This should be
contrasted with Discretionary Costs, which are avoidable costs.
13. Write short notes on explicit and Implicit Costs.
Define Explicit Costs. How is it different from Implicit Costs?
Particulars Explicit Costs Implicit Costs
1. Meaning Costs which involve some cash
payment or outflow of resources.
Cost which do not involve any
cash payment at all.
2. Also known as Out – of – Pocket Costs. Economic / Notional / Imputed
Costs.
3. Measurement These are actually incurred,
and hence can be easily and
objectively measured.
They are not actually incurred.
They cannot be easily measured
and involve subjective
estimation.
4. Recording in books Recorded in books of account. Not recorded in books of
account.
5. Purposes Accounting, Reporting, Cost
Control & Decision Making.
Decision – Making like asset
replacement, make or buy, etc.
6. Examples Salaries, Wages, Advertisement,
etc.
Interest on own Capital, Rent of
own premises, Salary of
Abhimanyyu Agarrwal Jai Mata Di
9874311319 Page 8
Proprietor, etc. which are not
actually paid.
Note: Depreciation is considered as “Deemed Explicit Cost”, since the cost of Assets purchased (by
making a cash outlay in the past) is written off / apportioned during the life – time of those assets.
14. Enumerate the types of costs on the basis of Functions.
On the basis of Functions to which they relate, Costs are classified as under –
1) Production Cost: The cost of the set of operations commencing with supply of materials,
labour and services and ending with the primary packing of product. Thus it is equal to the
total of Direct Materials, Direct Labour, Direct Expenses and Production Overheads. In a
wider sense, it includes all Direct Costs and all Indirect Costs related to the production
(including Research and Development Cost apportioned, if any)
2) Administration Cost: The cost of formulating the policy, directing the organization and
controlling the operations of the undertaking, which is not directly related to Production,
Selling, Distribution, Research or Development activity or function. Examples: Office Rent,
Accounts and Secretarial Department Expenses, Audit and Legal Expenses, Directors
Remuneration, etc. (N 96)
3) Selling Cost: The cost of seeking to create and stimulate demand and of securing orders.
These are also called Marketing Costs. Examples: Market Research, Advertisement, Salaries,
Commission and Travel Expenses of Salesmen, Show – room Expenses, Cost of Samples, etc.
(N 99)
4) Distribution Cost: The cost of the sequence of operations which begins with making the
packed product available for dispatch and ends with making the reconditioned returned empty
package, if any, available for re – use. Examples: Distribution Packing (secondary packing),
Carriage Outwards, Maintenance of Delivery Vans, cost of transporting articles to central or
local storage, cost of moving articles to and from prospective customers (as in Sale or
Return), cost of warehousing saleable products, etc. (N 99)
5) Research Cost: Cost of development of new product and manufacturing process,
improvement of existing products, process and equipment, finding new uses for known
products, solving technical problems arising in manufacture and application of products, etc.
(N 92, M 96, N 98, N 00) 6) Development Cost: The cost of the process which begins with the implementation of the
decision to produce a new improved product, or to employ a new or improved method and
ends with commencement of formal production of that product or by that method, i.e. cost
incurred for commercialization / implementation of research findings. (N 92, M 96, N 98,
N 00) 7) Pre – Production Cost: The part of Development Cost incurred in making a trial production
run prior to formal production. (N 00)
8) Conversion Cost: The total of Direct Wages, Direct Expenses and Production Overhead,
Cost of converting Raw Materials to the finished stage or converting a material from one
stage of production to the other. (M 03)
Special Note as regards Distribution Costs:
Primary Packaging Cost is included in Production Cost. Secondary Packaging Cost is
Distribution Cost.
In exceptional cases, e.g. in case of Heavy Industries Equipment supply, installation cost at
delivery site for Heavy Equipments which involves assembling of parts, testing, etc is
included in Production Cost but not Distribution Cost. For example, Installation Cost of a
Gas Turbine at Plant Site is included in the Cost of Production of Gas Turbine.
15. What is a Cost Centre? Discuss the various types of Cost Centres.
1) Cost Centre: It is defined as –
Abhimanyyu Agarrwal Jai Mata Di
9874311319 Page 9
(a) A location – e.g. Chennai Factory, Kolkata Factory, etc.
(b) A person – e.g. Sales Manager L, M, etc.
(c) An item of equipment – e.g. Machinery P, Q or Process I, II, etc.
Or a group these, for which cost may be ascertained and used for the purpose of Cost
Control.
2) Classification : cost Centres can be classified as under –
(a) Based on Type:
Personal Cost Centre Impersonal Cost Centre
It consists of a person or group of persons. It consists of a location or an item
equipment (or group of these).
(b) Based on Role:
Production Cost Centre Service Cost Centre
It is a Cost Centre where Raw Material is
processed and converted into Finished
Product.
It is a Cost Centre which serves as an
ancillary unit and renders services to a
Production Cost Centre.
Here, both Direct and Indirect Costs are
incurred.
Here, only Indirect Costs are incurred.
There are no Direct Costs, as there is no
measurable and saleable output.
Examples: Machine Shops, Welding
Shops and Assembly Shops, etc.
Examples: Power – House, Gas Production
Plant, Material Service Centres, Plant
Maintenance Centres, etc.
(c) Based on Activity:
Operation Cost Centre Process Cost Centre
It consists of machines and / or persons,
carrying out similar operations.
It consists of machines and / or persons,
engaged on a specific process or a
continuous sequence of operations.
All machines / operators performing the
same operation are brought together under
a Cost Centre, the purpose being
ascertainment of cost of each operation
irrespective of its location inside the
factory.
Cost is analysed and related to a series of
operations in sequence. Generally, these
constitute a single location, as in Oil
Refineries and other process industries.
16. Define a Cost Unit. Give suitable illustrations.
1) Cost Unit is a unit of production, service or time or combination of these, in relation to which
costs may be ascertained or expressed. It should be one with which expenditure can be most
readily associated.
2) Cost Unit is a form of measurement of volume of production or service. This unit is generally
adopted on the basis of convenience and practice in the Industry concerned.
3) Cost Units differ from one business to the other. They are usually units of physical
measurement, e.g. number, weight, area, volume, time, length and value.
17. Define a Cost object. Give suitable illustrations.
1. Cost object is anything for which a separate measurement of cost is desired.
2. Cost object is defined as any unit of Cost Accounting selected with a view to accumulating all
cost under that unit.
3. Cost objects may be a product, a service, a project, a customer, a brand category, an activity, a
programmed, a division or department, a group of Plant and Machinery, a group of employees
or a combination of several units.

18. Write short notes on the various methods of costing.
Businesses vary in their nature and in the type of products or services they produce. Hence,
different methods of cost ascertainment are used in different businesses. Costing methods to
be employed are determined based on – (a) the method of production and (b) the unit of cost
used. The various methods of costing are –
METHODS OF COSTING
For Goods For Services- Operating Costing
Specialized Production Standardised Production
Job Batch Contract Single / Unit Process / Joint
Costing Costing Costing /Output Operation and By-
Costing Costing Product
Costing
Work is
undertaken
on receiving
a customer’s
order /
assignment.
Output under a
Job consists of
similar units, it
is not feasible
to ascertain
cost per unit.
Execution of
work is
distributed
over two or
more
financial
years.
Product(s) is
produced
from single
process.
One product is
produced from
a series of
sequential
processes.
Many
products are
produced
from many
sequential &
parallel
processes.
Multiple Costing: It represents a combination of two or more methods of costing given above. For
example, if a Company manufactures Cars including its components, the component parts will be
costed by Batch Costing System, but the cost of assembling the Car will be computed by the Single or
Output Costing method. The whole system of costing is known as Multiple Costing.
The following table summarizes the various methods of costing applied in different industries-
Nature of Output Method Cost Ascertainment Examples of Industries
A. Based on
customer
specifications:
- Single Unit Job Costing For each order / job /
assignment.
Automobile Workshops,
Interior Decoration, etc.
- No. of similar
units
Batch costing For each batch / lot of
units produced.
Pharmaceuticals, Printing
Press i.e. visiting cards,
invitations, etc.
- Execution of
works
Contract Costing For each contract. Roads, Brickworks,
Colliery, Paint

20. Write short noted on Direct Expenses.
1. Direct Expenses or Chargeable Expenses: These are expenses other than materials and
labour which can be allocated directly to jobs, products, processes, cost centers’ or cost
units. Direct Expenses are “cost other than material and wages which are incurred for a
specific product or saleable services”.
2. Nature of Direct Expenses: (a) These are expenses other than Direct Materials and
Direct Labour, (b) These are either allocated or charged completely to Cost Centres or
Cost Units, (c) These are included in the Prime Cost of a product.
3. Examples:
(a) Hire Charges of special machinery
or plant for a particular production
order or job.
(b) Payment of Royaties.
(c) Cost of special moulds, designs &
patterns.
(d) Sub-Contracting Expenses or
outside work costs, where jobs are
sent out for special processing.
(e) Experimental cost before
undertaking the job.
(f) Travel & Conveyance Expenses for
a particular job.
4. Documentation: The basic document which is used for charging of Direct Expenses to
products or batches or work order, is the Invoice received from Suppliers of such service.
The payment to supplier of service is made on the basis of the Invoice, and the expenses
are booked in the accounts.

5. Identification of Direct Expenses: For the identification of Direct Expenses with the
main product or service, the code number of that product or service should be inscribed
on invoice received from supplier of services. For example, if a machine is hired to
complete a particular product, then the Hire Charges paid for that machine is a Direct
Expenses of that particular product. For charging these Hire Charges to that particular
product, the invoice / bill received towards Hire Charges should be coded / inscribed with
the Product Code, to ensure that this expense is charged to that particular product.
Alternatively, if cash is paid, then the Cash Book Analysis will show the Product Code
which is to be charged with the cost of hiring machinery.

1. What is Just in Time (JIT) Purchases? What are its advantages?
Just in Time (JIT) Purchases means organizing the purchase of goods or materials such that
their receipt in Stores Department immediately precedes their use. The advantages of JIT
purchases are-
1. Cost Savings: JIT purchases results in cost savings. The costs of stock-out, inventory
carrying, materials handling and breakage are reduced.
2. Cost of consumption: due to frequent purchases of Raw Materials, its issue price will be
equal to the replacement price. The method of pricing for valuing materials issues will be
realistic to reflect current costs.
3. Supplier Co-ordination: Suppliers of Raw Materials co-operate with the Company and
supply requisite quantity of goods or materials for which order is placed just before the
start of production.
4. Materials Management: Goods spend less time in warehouses or on store shelves before
they are exhausted. Risk of obsolescence is thereby reduced.
2. What is ABC Analysis?
1. Meaning: ABC Analysis is a form of inventory control wherein different degrees of
control are exercised over different items of materials, on the basis of the investment
(value) involved. For example, in the making of aircraft, cryogenic engines involving
high costs will be monitored closely, while cost of tyres, nuts and bolts, etc. will be given
comparatively lesser attention.
2. Categorization: Under this system, Raw Materials Items are divided into three categories
according to their importance in terms of value and frequency of replenishment during a
period. These categories are –
(a) A Category –Highly Important.
(b) B Category - Moderately important.
(c) C Category – Least Important.
3. Analysis & Control: The three categories are classified and differential control is
established as under-
Category % in Total
Value
% in Total
Quantity
Extent of Control
A 70% 10% Constant and Strict Control through
Budgets, Ratios, Stock Levels, EOQ,
Procedural checks, etc.
B 20% 20% Need based selective control – periodic
review – not strict or excessive.
C 10% 70% Little control – focus on saving associated

costs.
Note: ABC Analysis is also called by other names such as HML (High Moderate Low)
