Standard Costing UNIT V
Standard Costing UNIT V
Standard costs are predetermined cost which may be used as a yardstick to measure the efficiency with which
actual costs has been incurred under given circumstance. To illustrate, the amount of raw material required to
produce a unit of product can be determined and the cost of that raw material estimated. This becomes the
standard material input. If actual raw material usage or costs differ from the standards, the difference which is
called ‘variance’ is reported to manager concerned. When size of the variance is significant, a detailed
investigation will be made to determine the causes of variance
According to the chartered Institute of Management Accountants (C.I.M.A) London, “Standard cost is the
predetermined cost based on technical estimates for materials, labour and overhead for a selected period of time
for a prescribed set of working conditions.”
The Institute of Cost and Works Accountants defines standard costs as “Standard costs are prepared and used to
clarify the final results of a business, particularly by measurement of variations of actual costs from standard costs
and the analysis of the causes of variations for the purpose of maintaining efficiency of executive action.”
Thus standard costs is a predetermined which determines what each product or service ‘should be’ under given
circumstances. From the above definitions we may note that standard costs are:
    1.      Pre-determined cost: Standard cost is always determined in advance and ahead of actual point of time
            of incurring of costs.
    2.      Based on technical estimated: Standard cost is determined only on the basis of a technical estimate
            and on a rational basis.
    3.      For the purpose of Comparison: The very purpose of standard cost is to aid the comparison with
            actual costs.
    4.      Based for price fixing: The prices are fixed in advance and hence the only variation basis is the
            standard cost.
Estimated Cost
Estimates are predetermined costs which are based on historical data and is often not very scientifically
determined. They usually compiled from loosely gathered information and therefore, they are unsafe to use them
as a tool for measuring performance. Standard costs are predetermined costs which aims at what the cost should
be rather then what it will be. Both the standard costs and estimated costs are used to determine price in advance
and their purpose is to control cost. But, there are certain differences between these two costs as stated below:
The following are some of the important differences between standard cost and estimated cost:
Budgeting may be defined as the process of preparing plans for future activities of the business enterprise after
considering and involving the objectives of the said organisation. This also provides process/steps of collection
and preparation of data, by which deviations from the plan can be measured. This analysis helps to measure
performance, cost estimation, minimizing wastage and better utilisation of resources of the organisation. Thus,
budgets are prepared on the basis of future estimated production and sales in order to find out the profit in a
specified period.
The objective of the standard costing and budgeting is to achieve maximum efficiency and cost control. Under
both the systems actual performance is compared with predetermined standards, deviations, if any, are analysed
and reported. Budgeting is essential to determine standard costs while standard costing is necessary for planning
budgets. Both are complimentary in nature and in determining the results. Besides similarities there are certain
differences between standard costing and budgeting which are as follows:
VARIANCE ANALYSIS
Definition:      The process of analysis variances by sub-dividing the total variance in such a way that
                 management can assign responsibility for off-standard performance.
Interpretation of Variances:
Each variance is interpreted accordingly and by “interpretation” we mean making a decision whether the variance
is favourably or unfavorable and attaching responsibility.
-       When actual cost is less than the standard cost, the difference is considered “FAVOURABLE” or
        CREDIT VARIANCE.
-       On the other hand when the actual cost exceeds the standard cost, the difference is termed as
        UNFAVOURABLE or a DEBIT VARIANCE.
-       Ordinarily, a favourable variance is a sign of efficiency of the organisation whereas an unfavourable
        variance is a sign of inefficiency.
The division of variance into controllable and uncontrollable is important from the view point of management as it
can place more emphasis on controllable variance and thus facilitates to the principle of management by
exception.
Classification of Variances
Variances may be classified into two categories viz.,
2. Sales variances.
The cost variance may again be sub-divided into variances for each element of cost as shown in the following
chart:

                                                                              Sales            Sales
                                                                              Value            Margin
COST VARIANCES:
In the manufacturing function, cost variances are classified on the basis of the elements of cost viz. material, labor
and expense variances.
In cost analysis the standard cost of each element of cost is reconciled with actual cost and difference is called cost
variance or total variance. The cost variance has two components:
                                               Price
                                               variance                       Mix variance

Illustration
In the manufacture of a product, 200 employees are engaged at a rate of Rs..50 per hour. A five-day
week of 40 hours is worked and the standard performance is set at 250 units per hour. During the first
week in January, six employees were paid at Rs..45 an hour and four at Rs. .56 an hour, the remaining
were paid at the standard rate. The factory stopped production for one hour due to power failure.

SALES VARIANCE
Although a discussion on standard costing should be limited to cost variances, it is considered incomplete unless
sales variances are appended with it as a part of comprehensive information presented to the Management.
(i)    Turnover method or Sales Value; and
In the sales value method, variances are calculated on the basis of the figure of the pre-determined sales and
actual sales whereas in sales margin method, calculation of variances is done on the basis of the figures of
predetermined profit and actual profit.
As the first method fails to measure the effect/impact of deviations of actual sales from planned sales, the
management is usually interested in the sales margin approach. This is to say the management is usually
interested in knowing to what extent actual sales margin differed from budgeted sales margin – and not on why
budgeted sales differed from actual sales, therefore sales margin approach is preferable.
Illustration:
During the first quarter of 2001, Meccer Ltd’s sales was budgeted to be 9 000 units but the actual sales
turned out to be 10 000 units. You are required to analyze this information and provide the information
as indicated below.

Required:
Calculate the following:
(i)    Sales price variance
(ii)   Sales quantity variance
(iii)  Cost price variance
(iv)   Cost-quantity variance
(v)    Total Gross Profit variance.
SOLUTION
1.     Selling Price Variance=       (AP – SP) x AQ
This is the impact of the difference between the standard cost of sales and the actual cost of sales on
the actual quantity sold.
This is the impact of the difference between the actual volume and the budgeted volume on the
standard cost of sales.
It goes without saying that standard costs can be used in almost every sphere of management and in
conjunction with almost all the different costing systems.
A variance exists when the actual situation differs from the standard or budgeted projection. Therefore it
is clear that the total of all the variance must be equal to the net difference between the standards
(budgeted profit) that was set and the actual performance achieved (actual profit). The total of all
variances put together must be equal to the difference between actual and budgeted costs.

Setting of standards:
A standard is an ideal which is anticipated and can be attained over a future period of time, normally in the next
accounting year. The cost accountant, departmental heads, foremen and technical experts should work together in
setting standards. Just like a budget committee, a committee should be formed to set standards.
TYPES OF STANDARDS
Current Standards:
        Fixed on the basis of current conditions and remain in operation for a limited period in the sense that they
        are revised at regular intervals. Current standards are of two types:
        (a)      Ideal standards:
                 This standard reflects the level of attainment on the basis of maximum possible level of efficiency
                 which may never be achieved.
        (b)      Expected (or Attainable) standards.
                 Reflects a level of attainment based on a high level of efficiency which is capable of being
                 achieved. It is best suited for control point of view because this standard reveals real variances
                 from the attainable performance levels.
Basic standard:
        The standard is established and operated without revision for a number of years to help forward planning.
        It is not suitable for cost control purposes.
Normal standard
        This standard is meant to smooth out fluctuations caused by seasonal and cyclical changes. It is difficult to
        follow such standards in practice because it is not possible to forecast performance with adequate accuracy
        for a long period of time. As such, normal standards have little relevance for planning and cost control.
