COST CONCEPT AND COST OBJECT
COST
CONCEPT AND COST OBJECT
The
dictionary meaning of cost is “a loss or sacrifice”, or “an amount paid or
required in
payment
for a purchase or for the production or upkeep of something, often measured in terms
of effort or time expended”. C I M A Terminology defines cost as
‘resources sacrificed or forgone to achieve a specific objective’. Cost is
generally measured in monetary terms.
Basics of Cost Accounting
Cost is
the amount of expenditure (actual or notional) incurred on or attributable to,
a specified thing or activity. Thus, material cost of a product will mean the
expenses incurred in procuring, storing and using materials in the product.
Similarly, labour cost will represent that part of payment made to the workmen
for time spent on the product during its manufacture. Again, the term ‘cost’
can hardly be meaningful without using a suffix or a prefix. The cost is always
ascertained with reference to some object, such as, material, Iabour, direct,
indirect, fixed, variable, job, process, etc. Thus, each suffix or prefix
implies certain attribute which will explain its nature and limitations.
Cost
object is defined by Charles T. Horngren as ‘any activity for which a separate
measurement of cost is desired’. It may be an activity, or operation in which
resources, like materials, labour, etc. are consumed. The cost object may be a
product or service, a project or a department, or even a program like
eradication of illiteracy. Again, the same cost may pertain to more than one
cost objects simultaneously. For example, material cost may be a part of product
cost as well as production department cost.
COST
MANAGEMENT
The
techniques and process of ascertaining cost involve three steps, viz.
(i)
Collection of expenditure or cost data,
(iii) Classification
of expenditure as per cost elements, function, etc. and
(iii)
Allocation and apportionment of expenditure to the cost centres and cost units.
The
system accumulates and classifies expenditure according to the elements of
costs, and then, the accumulated expenditure is allocated and apportioned to
cost objects i.e. cost centres and cost units. We should, therefore, know what
are cost elements, cost centres and cost units.
Elements of
Cost
For the
purpose of identification, accounting and control, breakup of cost into its
elements is essential. Elements are related to the process of manufacture i.e.
the conversion of raw materials into finished products. Costs are normally
broken down into three basic elements, namely, material, labour and expense.
Material cost includes all materials consumed in the process of manufacture up
to the primary packing. Labour cost includes all remuneration paid to the staff
and workmen for conversion of raw materials into finished products. Expenses
consist of the cost of utilities and services used for the conversion process
including notional cost for the use of owned assets.
Each of
the cost elements can be further divided into direct and indirect cost. Direct
costs are those which can be identified with or related to the product or
services, so much so that an increase or decrease of an unit of product or
service will affect the cost proportionately. Indirect cost, on the other hand,
cannot be identified or traced to a given cost object in economical way and are
related to the expenses incurred for maintaining facilities for such production
or services. Thus, the elements of cost may be summarised as follows – (a)
Direct materials and indirect materials, (b) Direct wages and indirect wages,
(c) Direct expense and indirect expense
Cost and Management Accounting
The
aggregate of direct materials cost, direct wages and direct expense is called Prime
cost, while indirect materials cost, indirect wages and indirect expenses
are collectively called overhead cost.
Overheads
are classified into production overheads i.e. indirect costs relating to
manufacturing activities, administration overheads i.e. costs relating to
formulating the policy, directing the organisation and controlling operations
and selling and distribution overheads i.e. indirect costs relating to the
activity of creating and stimulating demand and securing orders as well as operations
relating to distribution of goods from factory warehouse to customers. Factory cost,
cost of production and cost of sales are arrived at by adding respective
overheads to prime cost, factory cost and cost of production as indicated in
the chart below :–

Allocated
and Apportioned Cost
Cost
allocation is the allotment of the whole items of costs to cost centres or
cost units. Cost apportionment refers to the allotment of proportions of
item of cost to cost centres or cost units. A cost which is allocated to a cost
centre is a direct cost of that cost centre, whereas the cost which is
apportioned to different cost centres on suitable basis is an indirect cost of
that cost centre. Thus, direct costs are allocated, since they can be directly
identified with a cost centre or cost unit, and indirect costs are apportioned
expenditure. The concept of direct and indirect cost is very important for
costing purposes.
Cost Centre
Cost
centre is defined as a location, person or item of equipment (or group
of them) in respect of which costs may be ascertained and related to cost units
for the purposes of cost control. It is the smallest segment of activity or area
of responsibility for which costs are accumulated.
Thus
cost centres can be of two kinds, viz.
(a) Impersonal
cost centre consisting of a location or item of equipment (or group of
these)
such as machine shop, and
(b) Personal
cost centre consisting of a person or a group of persons such as factory
manager,
sales manager, etc.
Cost
centres are also classified in manufacturing concerns into production and
service cost centres. Production cost centres relate to those centres where
production or manufacturing
activities
take place. Service cost centres are those, which are ancillary and render
services to the production cost centres, so that manufacturing activities can
take place. In a biscuit manufacturing company, making, baking and packing are
production cost centres while personnel, purchase, stores, canteen, accounts
are service cost centres.
The
main purpose of cost centre is two fold :–
(i)
Recovery of cost: Costs are collected, classified and accumulated in respect of a
location, person or an item of equipment and then the costs are distributed
over the products for recovery of incurred cost, and
(ii) Cost
control: Cost centres assist in making a person responsible for the control
of expenditure incurred by the cost centre. Manager of each cost centre shall
control costs incurred in his area of responsibility.
The
size of the cost centre depends on the activity and operation, and feasibility
of cost
control.
Sub-cost centres are created if the size of the cost centres become too big
from
control
point of view.
Cost Unit
While
cost centres assist in ascertaining costs by location, person, equipment,
operation or process, cost unit is a unit of product, service or a
combination of them in relation to which costs are ascertained or expressed.
The selection
of suitable cost unit depends upon several factors, such as, nature of
business, process of information, requirements of costing system, etc. but
usually relates to the natural unit of the product or service. For example, in
steel and cement industry, the cost unit is ‘tonne’, while in transportation
services, the unit may be passenger-kilometre or tonne-km, etc. It may be noted
that while the former is a single cost unit, the latter is a composite unit, i.e.
a combination of two units. A few examples of cost units are given below :–

COST
CLASSIFICATION
Cost
classification refers to the process of grouping costs according to their
common
characteristics,
such as nature of expense, function, variability, controllability and
normality.
Cost
classification can be done on the basis of time, their relation with the
product and accounting period. Cost classification is also made for planning
and control and decision making. Thus, classification is essential for
identifying costs with cost centres or cost units for the purpose
of
determination and control of cost :
(a) By
nature of expenses: Costs can be classified into material, labour and
expenses as explained earlier.
(b) By
function: Costs are classified, as explained earlier, into production or
manufacturing cost, administration cost, selling and distribution cost, research
and development cost.
—
Production cost begins with the process of supplying material labour and services
and ends with primary packing of the finished product.
—
Administration cost is the aggregate of the costs of formulating the policy, directing
the organisation and controlling the operations of an undertaking, which is not
related directly to production, selling, distribution, research and development
activity or function.
—
Selling cost refers to the expenditure incurred in promoting sales and
retaining customers.
—
Distribution cost begins with the process of making the packed product
available for despatch and ends with making the reconditioned returned empty
package available for reuse.
—
Research and development cost relates to the costs of researching for new or improved
products, new application of materials, or new or improved methods, processes,
system or services, and also the cost of implementation of the decision including
the commencement of commercial production of that product or by that process or
method.
—
Pre-production cost refers to the part of development cost incurred in making trial
production run preliminary to formal production, either in a new or a running factory.
In a running factory, this cost often represents research and development cost
also. Pre-production costs are normally considered as deferred revenue expenditure
and are charged to the cost of future production.
(c) By
variability: Costs are classified into fixed, variable and semi-fixed /
semi-variable
costs
according to their tendency to vary with the volume of output.
— Fixed
costs tend to remain unaffected by the variation or change in the volume of
output, such as supervisory salary, rent, taxes, etc.
— Variable
costs tend to vary directly with volume of output, such as direct material,
direct labour and direct expense.
— Semi-fixed/semi-variable
cost is partly fixed and partly variable, such as telephone expense,
electricity charges, etc.
(d) By controllability: Costs can be
classified under controllable cost and uncontrollable cost.
—
Controllable cost can be influenced by the action of a specified member of an undertaking.
—
Uncontrollable cost cannot be influenced by the action of a specified member of
an undertaking.
(e) By
normality : Costs can be divided into normal cost and abnormal cost. —
Normal cost refers to the cost, at a given level of output in the conditions in
which that level of output is normally attained.
—
Abnormal cost is a cost which is not normally incurred at a given level of output
in the conditions in which that level of output is normally attained.
(f) On
the basis of time : Costs, may be classified into historical or actual cost
and
predetermined
or future cost.
—
Historical cost relates to the usual method of determining actual cost of
operation based on actual expenses incurred during the period. Such evaluation
of costs takes longer time, till the accounts are closed and finalised, and
figures are ready for use in cost calculations.
—
Predetermined cost as the name signifies is prepared in advance before the actual
operation starts on the basis of specifications and historical cost data of the
earlier period and all factors affecting cost. Predetermined cost is the cost determined
in advance and may be either estimated or standard.
—
Estimated cost is prepared before accepting an order for submitting price quotation.
It is also used for comparing actual performance.
—
Standard cost is scientifically predetermined cost of a product or service
applicable during a specific period of immediate future under current or
anticipated operating conditions. The method consists of setting standards for
each elements of cost, comparing actual cost incurred with the standard cost,
evaluating the variance from standard cost and finding reasons for such
variance, so that remedial steps can be taken promptly to check inefficient
performances.
(9) In
relation to the product : Costs may be classified into direct and indirect
costs.
—
Direct costs are those which are incurred for a particular cost unit and can be
conveniently linked with that cost unit. Direct costs are termed as product
cost.
—
Indirect costs are those which are incurred for a number of cost units and also
include costs which though incurred for a particular cost unit are not linked with
the cost unit. Since such costs are incurred over a period and the benefit is
mostly derived within the same period, they are called period costs.
(h) Cost
analysis for decision making: Here costs are classified under relevant
costs
(e.g.
marginal cost, additional fixed cost, incremental cost, opportunity cost) and
irrelevant costs (e.g. sunk cost, committed costs, etc.)
METHODS OF
COSTING
Various
methods of ascertaining costs are available to suit the business need. But the
basic principles are the same in every method. The choice of a particular
method of costing depends on the nature of business of the concern.
There
are two basic methods of costing viz. – (a) Specific order or job costing (b)
Continuous operation or process costing
All
other methods are either variation of job or process costing or are just
techniques used for particular purpose under specific conditions. Brief
description of each of the methods are as follows:
Job Costing
Job
costing is the basic costing method applicable to those industries where the
work consist of separate contracts, jobs, or batches, each of which is
authorised by a specific order or contract. The most important feature is that
each job or order can be identified at each stage of production and therefore,
costs which can be directly identified with a job or order is charged to that
job or order. A share of indirect expenses is also charged to the same.
Variation of job costing are contracts costing and batch costing.
— Contract
costing is the form of specific order costing, generally applicable where
work is undertaken to customer’s special requirements and each order is of long
duration, such as building construction, ship building, structurals for bridge,
civil construction, etc. The work is usually done outside the factory.
— Batch
costing is that form of specific order costing which applies where similar
articles are manufactured in batches either for sale or for use within the
undertaking. Costs are collected according to batch order number and total
costs are divided by total numbers in a batch to arrive at unit cost of each
job. The method is applicable in aircraft, toy making, printing industries,
etc.
Operation
Costing – Process and Services
Process
costing method is applicable where goods or services result from a sequence
of
continuous or repetitive operations or processes and products are identical and
cannot be segregated. Costs are charged to processes and averaged over the
units produced during the period. Examples are food processing, chemical, dairies,
paints, flour, biscuit making, etc. Variations of process costing are found in
single or output costing, operation costing, departmental costing as explained
below:
—
Single or output costing is used when the production is uniform and identical
and a
single
article is produced. The total production cost is divided by the number of
units produced to get unit or output cost. Examples are mining, breweries,
brick making, etc. — Operation costing refers to the methods where each
operation in each stage of production or process is separately costed.
Thereafter, the cost of finished unit is determined. This is suitable to
industries dealing with mass production of repetitive nature — for example, motor
cars, cycles, toys, etc.
—
Departmental costing refers to the method of ascertaining the cost of operating
a department or cost centre. Total cost of each department is ascertained and
divided by total units produced in that department to arrive at unit cost. If
one product passes through a number of departments for completion, cost of each
department will be picked up and the total unit cost will be the aggregate of
unit cost of the departments through which the product passes.
Service or
Operating Costing
Operating
costing is applicable to service organisation that do not make or sell
tangible goods but render services. Examples are transportation companies,
hotels, hospitals, schools, electric and gas generation and distribution, etc.
Cost of providing and operating a service is ascertained and unit cost is found
out by dividing total cost of units of services rendered. Composite units, such
as tonne-mile, passenger-kilometre, KWH, etc. are generally used.
Composite
or multiple costing: The manufacture of certain products involve a lot of
complexities
and therefore, any one of the basic methods of job or process costing cannot be
used for collecting and presenting product cost. In fact, industries making
complex products such as cycles, automobiles, aeroplanes, radios, etc. use
combination of various costing methods and the methods are known as composite
or multiple costing.
TECHNIQUES
OF COSTING
In each
of the costing methods, various techniques may be used to ascertain cost,
depending on the management requirement. These techniques may be grouped as
follows :
A. Absorption
costing : It refers to the ascertainment of costs after they have been
actually incurred. As per this system, fixed as well as variable costs are
allotted to cost units and total overheads are absorbed by actual activity
level. Absorption costing is termed as total costing, since total costs are
ultimately allotted to cost units. It is also termed as historical or traditional costing. However,
since costs are ascertained after they have been incurred, and substantial
time-gap exists between occurrence of expenditure and reporting off cost
information, it does not help to exercise cost control.
B. Marginal
costing : It refers to a principle whereby variable costs are charged to
cost
units
and the fixed costs attributable to the relevant period is written off in full
against the contribution for that
period. Contribution is the difference between sales and variable
or
marginal cost of sales. Marginal costing is also known as direct or variable
costing. It is a valuable aid to management in taking important policy
decisions, such as product
pricing,
choosing product mix, decision to make or to buy, etc.
C. Standard
costing: It refers to the technique which uses standards for costs and revenues
for the purpose of control through variance analysis. Standards are established
for each cost element on a scientific basis for immediate future period, and
actuals are compared against the standard. Variances from standards are
analysed, reasons established and corrective action taken to stop recurrence of
inefficient operation. Thus, standard costing is extremely helpful for cost
control. Standard costing is normally used along with budgetary control, which
refers to the establishment of budgets relating to responsibilities of
executive to the requirements of a policy and the continuous comparison of
actual with budgeted results, either to secure by individual action the objective
of that policy or to provide a basis for its revision .Absorption costing
system and marginal or direct costing system can be used in conjunction with
standard costing system.
D. Differential
costing: It is defined as a technique used in the preparation of adhoc information
in which only costs and income differences between alternative courses of
action
are taken into consideration. It considers only the additional costs and
additional
revenues
arising out of the decision regarding addition of a project. Similarly,
incremental costing technique considers incremental costs and incremental
revenue arising out of a decision to change the level of nature of activity.
E. Uniform
costing: It refers to the use by several undertakings of the same costing system
i.e. the same basic methods, principles and techniques. This is not a distinct method
of costing. The system is applied by a number of units of the same undertaking
or
several undertakings within the same industry with a view to promote operating efficiency
by comparing inter-unit or interfirm performance data. Trade associations and
multinational companies often use this system.
Concept And Meaning Of Cost
Control
Cost
Control
Control
is function that make sure that actual work is done to fulfill the original
intention. It is a widely accepted notion that the actual costs for each cost
element should be within the budget. Like hospitality and entertainment,
expenses in a marketing department should not exceed the budget allowed for
that head for the given period. Cost control is thought of as a managerial
effort to attain cost goals within a particular environment.
Cost
control is not a specific program. Rather, it is a routine activity to be
frequently carried out. Cost must be controlled, otherwise, there will be
wastage, misappropriation and embezzlement. Checking such wastage and
misappropriation of resources is a continuous activity. A firm exercising a
better control last year does not mean that it has now been relaxed from the
cost control function. Cost control relies heavily on accounting techniques.
Some of the key cost control techniques are responsibility accounting control
system, standard costing, budgetary control and cost management ratios.
Therefore, cost control includes the routine management of the organizational activities, such as controlling of wastage, misappropriation, loss of work time, set up time etc.
Therefore, cost control includes the routine management of the organizational activities, such as controlling of wastage, misappropriation, loss of work time, set up time etc.
Concept And Meaning Of Cost
Reduction
Cost
reduction means conducting some innovations in the way of working in a new
style, so that the excess costs of production and operation could be
eliminated. Cost reduction programs are directed toward specific efforts to
reduce costs by improving methods work arrangements and products. Cost
reduction can be made in different areas and stages of production, storing and
distribution process by applying more advanced and scientific techniques of
operation. So, a cost reduction program needs a research and development
activity.
Cost
reduction programs may require a bulk amount of research and development
budget, but once a new technique is introduced, it gives competitive advantages
for the long period.
The
aim of cost reduction is to see whether there is any possibility of bringing
about a saving in the costs incurred on materials, labor, overheads etc.
Cost
reduction is possible through the following improvements:
*
Obtaining more outputs from the same inputs and facilities.
*
Using a lesser quantity of inputs to obtain the same output .
*
Simplifying the methods of distribution.
*
Improving the location and layout of plant, warehouse and other resources.
Differences Between Cost
Control And Cost Reduction
Following
are the main differences between cost control and cost reduction:
1. Focus
1. Focus
Cost
control focuses on the minimization of wastage than the reduction of cost. Cost
reduction focuses on minimization of cost through new production process,
improved plant layout, scientific material handling etc.
2.
Basis Of Application
Cost
control is routinely applied on a continuous basis. Cost reduction is applied
when an opportunity for cost reduction is identified which offers a competitive
advantage for a longer time.
3.
Use Of Accounting Techniques
Cost
control heavily relies on accounting techniques. Cost reduction may not involve
the use of accounting technique.
The
following are the widely used techniques of cost reduction:
1. Just-In-Time (JIT) System
1. Just-In-Time (JIT) System
The
main aim of JIT is to produce the required items, at the required
quality and quantity, at the precise time they are required. JITpurchasing
requires for the items where too much carrying costs associated with holding
high inventory levels. purchasing system reduces the investment in inventories because of frequent
order of small quantities.
2. Target Costing
2. Target Costing
Target
costing refers to the design of product, and the processes used to produce it,
so that ultimately the product can be manufactured at a cost that will enable the
firm to make profit when the product is sold at an estimated market-driven
price. This estimated price is called target price.
3.Activity Based Management(ABM)
3.Activity Based Management(ABM)
Activity
based management is the use of activity based costing to
improve operations and to eliminate non-value added cost. The main goal of ABM
is to identify and eliminate non-value added activities and costs.
4.Life Cycle Costing
4.Life Cycle Costing
Life
cycle costing estimates and accumulates costs over a product's entire life
cycle in order to determine whether the profits earned during the manufacturing
phase will cover the costs incurred during the pre-and-post manufacturing
stage.
5. Kaizen Costing
Kaizen costing is the process of cost reduction during the manufacturing phase of an existing product. The Japanese word 'Kaizen' refers to continual and gradual improvement through small activities, rather than large or radical improvement through innovation or large investment technology.

6.Business
Process-re-engineering
Re-engineering
is a complete redesign of process with an emphasis on finding creative new ways
to accomplish an objective.The aim of business process re-engineering is to
improve the key business process in an organization by focusing on
simplification, cost reduction, improved quality and enhanced customer
satisfaction.
7.Total Quality Management(TQM)
7.Total Quality Management(TQM)
Under
the TQM approach, all business functions are involved in a process of
continuous quality improvement.
8. Value chain
8. Value chain
Value
chain analysis is a means of achieving higher customer satisfaction and
managing costs more effectively. The value chain is the linked set of value
creating activities all the way from basic raw materials' sources, component
suppliers, to the ultimate end-use product or service delivered to the customer.
9.
Bench Marketing
Bench
marketing is a continual search for the most effective method of accomplishing
a task by comparing the existing methods and performance levels with those of
other organizations or other sub-units within the same organization.
10. Management Audits
Management audits, also known as performance audits, can be used to facilitate cost reduction in both profit and non-profit organizations. Management audits are intended to help management to do a better job by identifying waste and inefficiency and recommending a corrective action
