CHOICE
OF METHOD COST CALCULATION
All company for effective and
rational work must select the optimal method of cost calculation. A choice and
order formation of prices on the company are not regulated, the calculation is
made not for tax purposes and for internal aims of the company. The correct
cost accounting in the organization plays a considerable role, because
organization gets possibility of influence on the expenses of production, and
thus the very organization as a whole.
Primary in the
choice of calculation there is direction of account in an administrative
account. Under the direction of accounting theory refers to activities or part
is understood areas of activity in which you want to keep focused on the
production of records. Simpler speaking, if user needs information about the
cost of their specific management objectives, these objectives are the focus of
accounting. In practice, depending on a specific of the industry and
enterprise, excluding areas can be varied, as investigated in more detail, for
example:
- It is an assortment of products;
- The possibility of complementary
and alternative orders;
- It is pricing of products;
- The cost of stocks for management
decisions;
- The cost of maintaining a
particular department;
- Costing of certain goods.
All these brought
directions over of account contain the necessary information about the cost of
manufactured products in any enterprise. Therefore, determination of the choice
of method cost one unit of output is currently difficult. Cost calculation - is
a method of correct and accurate pricing on products in order to determine the
efficiency and profitability of the company. Methods of calculation of
production are determined depending on the method of reflection costs in the
enterprise and their calculation. Cost accounting and cost calculation is based
on any enterprise regardless of financial and tax accounting, as the choice of
the method of cost calculation is determined by the management decisions of
managers and company administration. Therefore, methods of cost accounting in
the financial and management accounting can differ materially.
In international
and national practice, using both traditional methods of calculation of the
cost production and functional methods, presented in Table 1.

Traditional
systems of calculation work effectively where overhead support production
processes represent a small proportion of the in direct costs. But to date,
auxiliary production costs play a very important role in shaping and
calculating the cost of production. Therefore, the functional systems of
calculation oriented company for consideration of information that allows for
the formation of value added industrial products. The main difference between
traditional systems of functional systems of calculation is reduced to the
different economic bases systems, namely the formation of the traditional
methods do not account for the cost of the business activity , and functional
fully take into account the level of business activity . The advantages of the
functional methods calculation, compared with conventional systems, are:
- Standard
evaluation (benchmarking);
- Strategic
analysis and management of financial investments and pricing;
- Obtaining
relevant information to make the right effectively - sound management
decisions;
- Estimation of
the costs on the basis of features that enhance the value of the product.
The disadvantages
of functional systems of calculation include:
- Obsolete methods in connection
with organizational changes;
- Information on the functions cost
effectively underplayed;
- Hard - supported the process of
describing cost functions.
Essence process
costing calculation is batch or mass - produces of the same type (or
approximately), the same quality and size of the products. Process costing used
by companies where manufacturing technology requires a separate run certain
parts of the process of production, that is, the production process is divided
into regularly recurring transactions. The main feature of process costing is
that together with the production process are accumulated production costs.
Cost level increases with each completed the process of making products. The
cost of products at process cost is calculated by dividing the total cost of
the total output by the number of items for the period. To effectively
determine the cost of each stage of manufacturing products in the enterprise
open a sub-account for each individual treatment process. Process costing is
the only method by which inappropriate to use analytical accounting calculation
items. Basically process costing used in the textile, metallurgy, oil refining,
food processing, chemical, glass and other industries. Since in this method is
mainly dominated by calculating the chemical, physical and thermal treatment
processes produce. The disadvantage of the method of process costing is the
difficulty of assessing the value of work in progress, as the cost of work in
progress is lower than that of the finished product. In this regard, the
company need arises to transfer unfinished production of equivalent units of
finished product.
Single standard
cost system - cost the company a universal lever for management, planning and
control of production costs. On the set, at the beginning of the reporting
period, standards possible to determine the desired amount of production costs
for manufacturing products. Also provided information on the standards identify
undesirable deviations, in order to make operational decisions. Rationing costs
for standard system - cost carried by cost: materials, direct labor and
overhead costs for repayment of wages and other personnel. Standards are set
per cost per finished product. Accounting standard in the system - cost is not
regulated, so it does not have a unified methodology to establish standards.
Emerging deviation between actual and standard costing for the years are going
in separate accounts is not debited on account of production and financial
results of the company. Deviation for a given system can be of four types:
materials, wages, overhead charge and gross profit. Deviation is calculated
based on three indicators in the context: for the price of materials, the
number of the materials used and the cumulative deviation of material
consumption. Variance analysis is calculated on the basis of labor: labor
productivity, the rate of wages and the cumulative deviation of the labor
costs. Variance overhead is of two kinds: deviation constant and variable
costs. Deviation of gross profit is classified into: deviations selling price
for sales volume and the cumulative deviation of the gross profit. The most
important thing in the standard costing - is strict control of deviations and
prompt surgical intervention when changes. If you do not keep conduct control,
standard - costing will be ineffective. Scope of standard costing quite
diverse: this enterprise with a non - product range, or an ad hoc production
technology. It may also be used when introducing a new product form. System
standard costing is one of the most used accounting systems throughout the
world, especially in Western mills, with developed market economies.
The main feature
of the job order costing is to determine the cost of one order, which
originally defined the necessary level of industrial production. Individual
characteristics of job order costing are: the use of special purpose equipment,
nonrecurring individually handcrafted products, hand fabrication processes. The
essence of this method is that all costs incurred relate to their place of
their occurrence, and included in the cost allocation path according to the
selected base distribution. Species of job order costing method are: special
order costing, costing of party goods and costing contract. Costing special
order determined by the order of the consumer per unit of output. An example
would be: sewing coats, car assembly, and more. Calculation of cost contract is
for a period of time of manufacture of a product or service, such as the torus
or the floor for two months of the year. Costing contract is characterized by
the length of time the manufacture of products or services, for example, two
months or half a year torus. An example of the calculation of the contract is
the construction of an ice palace. In order to improve control at contract
manufacturer products can bill for a specific date, on the basis of their costs
incurred. The specificity of this method is determined and scope - it is
small-scale and individual production.
Activity based
system (ABC) - calculation of the cost of the system is functional, and is used
internationally. Differences of this system from the traditional - is its
versatility. ABC system identifies activities (processes, operations) that
cause the occurrence of costs and examine the main cost drivers for these
activities. This system involves the classification of the main activities, the
definition of the cost of each activity, as well as identifying drivers (media)
costs. Method of calculation of the cost of production is a functional ABC
method, as it implies the recognition of costs of the functions themselves to
the final finished product. By this method, such rates are calculated
distribution costs that relate to a specific function. Under the function is
understood as a process that takes place at the company, such as retooling of
production equipment; marketing activities, delivery of materials from the
warehouse to the production equipment, logistics activities, etc. By the
conditions of application of the ABC include:
- Provided that the production
overheads are quite high compared to the direct costs, especially with the cost
of direct labor;
- Large variety of manufactured
products;
- A significant variety of overhead
resources (indirect labor, indirect materials, etc.) used in the production
process;
- Provided that the consumption of
overhead resources are not directly dependent on the volume of production.
The ABC system is based on the fact
that for each operation or activity has its own, quite accurate and inherent to
it, the cost factor, changes in the terms of which affect the cost of function.
Thus, the system monitors the ABC and applies causal relationships between cost
drivers (allocation bases, databases) and expenditures, and rather than
conditional relationship, as is common in traditional costing. The most
attractive feature is its ABC individual customization for a specific company;
you can use the ABC system in any field of activity. The functional ABC system
allows obtaining more accurate values for the cost of production.
However, the cost of implementing this system is far greater than when using
traditional costing systems.
In the 1930-ies
in the USSR on the basis of standard costing developed a normative method of
cost accounting and cost calculation. The main differences between the standard
costing and normative system accounting are as follows:
- Normative calculation begins with
defining the standard cost carrier costs and ends with formation actual unit
cost of production and the system standard costing is not related to the actual
unit cost of manufactured products;
- System standard-fare is a
collection of systems planning, forecasting and analysis of the costs incurred
and normative calculation is a system of measurement for all actual costs;
- In the system standard costing
used special accounts for cost accounting standards and their deviations, and
at standard costing of accounting is used only one special account for the
actual cost accounting differences from the normative;
- Using the standard costing
identified species deviations much more than when compared with normative
costing.
Normative method of calculation is
determined based on the company developed, norms and deviations from these
norms. Feature of this method is timely "signal" inefficient and
unsustainable use of resources of the enterprise. Therefore the norms of the
company should be systematically reviewed. The main characteristic of this
method is to control the identified deviations. Deviations are substantially
adverse and favorable. Favorable variances - those deviations which the actual
cost exceeds the regulatory and adverse deviation, on the contrary, standard
cost which exceeds the actual. The company, applying standard calculation
determines the deviation variable and fixed costs. The variable cost variance
analysis made: materials, salaries, and other overhead costs. In turn,
deviations in the materials classified as low bias and bias materials by volume
of the materials used. Deviations of wages are: deviation of labor productivity
and wage rate. The complexity of the normative method of calculation is
determine the causes of identified deviations. The production is a complex
mechanism, so it causes malfunction can be varied: inadequate regulations,
inefficient activity of the company, information about errors in evidence, as
well as uncontrollable factors.
Specificity of
direct costing is organize the separate account variable and fixed costs in
order to use this information for the effective management of the organization
in the field of production. Variable costs are included in the cost of
production, and fixed costs are charged to the income statement. Feature direct
costing is that costs are included and are scheduled only in the part of
variable costs, and the constants are taken into account and going in separate
accounts, for subsequent distribution in proportion to the financial result. In
management reports of the companies, who used direct costing should be
submitted two indicators: revenue and profit margin. It may be noted that
direct costing is a method of controlling management in the enterprise, based
on the true cost of production, and independent of fixed and overhead costs. On
the basis of direct costing analyzed the ratio of "cost - volume -
profit" (break-even analysis). The basis of this analysis is to find the
neither point where the enterprise will neither profit nor loss. The breakeven
point is a certain threshold of profitability, which characterizes this volume
of products in which the cumulative cost equals revenue. Break-even analysis is
a powerful tool for efficient planning and forecasting activities of the
enterprise. With the development of management accounting system direct costing
transformed into a system when the cost price is not only taking into account
the direct variable costs, but also indirect variable costs. Important specific
direct costing a systematic analysis between the volume of production, profit
and costs incurred in the ordinary course of business. Currently, direct
costing is widely used in Germany and Austria, this method sounds like a
"partial cost accounting" or "keeping the amount of
coverage", in the UK it is called "taking into account the marginal
cost" in France - "margin accounting" or "margin
account". Like all methods of
calculation of direct costing have its difficulties. Costs can change their
attitude to the volume of production during the year, while direct costing
would not be appropriate. The disadvantages of the system include: displays
overhead and fixed costs of control organization, not possible to determine the
average cost that may entail the wrong pricing policy of the enterprise.
The essence of
absorption costing is develop the most appropriate cost of production, as it
assumes the distribution of the total
and fixed and variable) costs between products sold and its residues.
Companies applying full cost method of cost allocation believe that production
is not possible if there are no fixed overhead costs, so they should be
allocated to the unit cost and are included in the resource estimate. Basically
absorption costing applies those enterprises that are involved in price competition.
The advantages of the system absorption costing include: the relationship with
financial accounting, in order to make external reporting; multivariate scope;
possible to calculate the most cost-effective products , the ability to
calculate the total cost of finished goods , work in process and inventory in
stock. Deficiencies of absorption costing: the inability of the comparative
cost analysis of different kinds of products, with a large range of products
possible wrong choice distribution base, which would entail a distortion cost.
Just in time
system is a special calculation system, which covers all aspects of the
production activities of the enterprise. Companies using this system are:
reduction of marriage, reducing congestion, increased flexibility, increased
productivity, reduced production time, as well as improving the ability to
provide new products into production, and improve existing products. Basically,
the system Just in time used in serial production. This is a fairly simple inventory
management system without any restriction to the minimum requirement of stocks
in which flows of material resources carefully synchronized with the need for
them, given by the production schedule of the finished product. Just in time
system is more bound demand, rather than the traditional method of
"throwing products to market". The basis of Just in time on the
principles: the complete elimination of stocks in production, minimizing their
warehouses and delivery of resources directly to jobs in small batches
maneuverable transport; abandonment of production in large lots, supply
production is carried out in small batches as needed , resulting in which
achieves a reduction in inventory levels. Just in time method is based on the
concept of logistics - "nothing will be made until this is not the need
arises". The advantages of this system can get rid of: the extra costs by
reducing unproductive expenditures, which consist, in particular, from the
release of excessive production; downtime of equipment and personnel detention
unnecessary storage space; losses associated with the presence of defects in
products.
In addition to
the methods of calculation and there are other methods of calculation, such as
target costing and kaizen costing. Target product - costing is forecasted
planned) cost improves the product in accordance with the target parameters.
Set boundaries forecast future price and size of the profit rate products,
based on which the search for materials, methods, technologies to find the
necessary amount of costs. This calculation system is effective in combination
with functional cost analysis.
Kaizen costing is
a method of calculation, which is aimed at the gradual improvement of product
quality, reducing costs and increasing profits of the enterprise. The term
"kaizen" is borrowed from the Japanese economy and means constant and
gradual improvement. The main purpose of kaizen costing is determined to
minimize the difference between the estimated and the actual cost of the
product by cost. Target costing aims to bring the cost of the product to the
desired level in the process of its development, and system kaizen costing aims
to develop individual cost items and the cost of the whole process of
production. Both systems can be used in management accounting, as in the
relationship, as well as independently. Typically, they are used in conjunction
it. Projected calculation of the cost starts at target costing, and then
calculation of (already actual costs) continues in the system kaizen costing.
Together, the two systems give the company a very valuable competitive
advantage in achieving lower than the competition, the level of costs and the
opportunity to choose a convenient pricing to capture or retain appropriate
market sectors.
Methods of
classification approaches to calculation of the cost are independent, so a
discussion regarding the method of calculation, which is better – process
costing, standard costing or absorption costing - is a manifestation of
misunderstanding the essence of these methods. In each case, a specific method
is used, or a combination of at least three aspects. For
example, a company that produces kitchen furniture to order, can be used as a
job order costing, and calculation of the regulatory system and possibly
direct costing. A company engaged in
the manufacture of soft drinks - or absorption costing, process costing. Also
ways of measuring the choice of method of cost calculation can affect not only
the tradition of organizing credentials, but the credentials of the whole
country tradition. The method of calculation under certain conditions of
production involves a specific calculation method, or combination of some of
them.
Effectively grounded and the optimal
choice of cost accounting and calculation will allow any organization to
maximize the profit of the company in view of the risks identified and to reduce
production costs.
