Standard Costing

And Variance Analysis

INTRODUCTION
• Control of cost is one the most important
objectives of cost and management
accounting
• Standard costing is a very important
system of cost control.
• Standard costing aims at eliminating the
wastages and increasing efficiency in
performances through setting up
standards for production expenses and
production performances
 Standard Costing
Standard costing is a technique which is used in many
industries, where production is of repetitive nature.
Standard costing is that technique in which the standard
cost is determined before starting the production.
Standard cost is a predetermined cost and such cost
indicates what a product should cost.
Standard cost is calculated by considering all the
situations ideal in nature.
Standard costs have been defined as the normal costs for
normal production efficiency at normal level of output.

 Definition of Standard Costing

The Institute of Cost and Management

Accountant ( ICMA UK) defines standard
costing as “the preparation and use of
standard costs, their comparison with
actual costs, and the analysis of
variances to their causes and points
of incidence.”

4
 Standard
The word standard means a criterion
(principle,measure).
A standard figure is one against which one
can measure an actual figure to see the
deviation.

5
 Standard Cost
A predetermined cost that is set based
on scientific analysis of material,
labour, and overhead requirements for
producing a product or service under
efficient operating conditions.
(Example: Material cost per unit fixed
as Rs.50 for production planning.)
In other words, standard cost is a predetermined cost that
should be attained under a given set of operating
conditions.

 Advantages Of Standard Costing

• Formulation of price and production policies

• Comparison and analysis of data
• Delegation of authority and responsibility
• Cost consciousness
• Better capacity to anticipate
• Better economy, efficiency, and productivity
• Preparation of periodical financial statements
• Facilitates budgeting

10
 Variance Analysis

• The deviation of actual from standard is called variance.

• When the actual cost is less than standard cost or actual
result is better than standard set, it is known as favourable
variance.
• On the other hand, when actual cost exceeds standards
cost or actual result is not up to standard, it is known as
unfavourable or adverse variance.

 Material Cost Variance
Material cost variance is the difference
between the actual cost of direct
materials used and standard cost of direct
material specified for the output
achieved.
This variance results from difference
between quantities consumed and
quantities of materials allowed for
production and from differences between
prices paid and prices predetermined.

21
 Material cost variance
Material cost variance = (Standard quantity of input
for actual production × SP) – (Actual quantity of
input × AP)

MCV= ( AQ ×AP) – (SQ ×SP)

Material cost variance = Material price variance +

Material usage variance

22
 Material price variance
 This is that portion of the material cost variance which is due to
the difference between the standard price specified and the actual
price paid.
 If the actual price is higher than the standard price, it would
result in adverse price variance and if the actual price is lower
than standard price, the result is favourable price variance.

Material price variance = Actual quantity (Standard price

– Actual price)
MPV= AQ (SP – AP)

23
 Material Usage Variance
 This is that portion of material cost variance which is due to
the difference between the standard quantity of actual
production and the actual quantity used.

 Formula:

Material Usage Variance = Standard price (Standard

quantity – Actual quantity)

MUV = SP ( SQ – AQ )

24
 Material Mixture Variance

 This is that portion of usage variance which is due to the difference

between the standard and actual composition of mixture.

 Formula:
 Material Mixture Variance = Standard price [Actual quantity -
RSQ]

 RSQ = Standard proportion of a particular mix × Actual Input

Total Standard Quantity

25
 Material Yield Variance
 When there is a loss in process industries, the material yield
variance can be calculated.
 This variance arises due to the difference between the standard
yield specified and actual yield obtained.
 This is also a portion of the material usage variance.

Formula:
MYV = (Actual yield – Standard Yield) × standard cost per unit
 MYV= (Actual loss – standard loss on actual input) × standard cost per
unit
Material yield variance = Material usage variance –
Material mix variance
26
 Material Sub-usage Variance
 When a product is produced from a mixture of two or more kinds of
material, there may arise material sub-usage variance.
 There can be two possibilities:
(a) Total quantity of material consumed and standard quantity are not
equal, and mix ratios are also different.
(b)Total quantity of material consumed and standard quantity are not
equal, but mix ratios are equal.

• It should be noted that material sub-usage variance is calculated

only when the quantity of wastage or output is not given.
• When these quantities are given, this variance will be the same as
material yield variance.
• This variance is also known as material revised usage variance or
27
material quantity variance.
 Formula:
Material sub-usage variance = (RSQ - SQ) × SP

 It can be seen from this formula that material

sub-usage variance is the analysis of variance in
basic standard quantity of each material.

28
29
 Labour Rate Variance
This is that portion of the labour cost variance which is
caused by the use of actual wage rate other than
predetermined.

Labour rate variance = Actual labour time (Standard wage

rate – Actual wage rate)

30
 Labour Efficiency Variance
It is the difference between the standard time and the actual
time spent multiplied by standard wage rate.

Labour efficiency variance = Standard wage rate

(Standard labour time – Actual labour time)

31
 Labour Idle Time Variance
 It is that portion of labour cost variance which is due to the
abnormal idle time of workers.
 While calculating labour efficiency variance, abnormal idle time
is deducted from the actual time spent to determine the real
efficiency of the workers.

 Idle time variance = Abnormal idle time × Standard wage rate

32
 Labour Yield Variance
It is computed on the basis of the increase or decrease in
the actual yield or output when compared to the standard.

Labour Yield Variance = [Standard yield in units

expected from the actual hours worked – actual yield] ×
Standard labour cost per unit

33
 Labour Mix Variance
 This variance arises due to the change in the composition or
mix of a group of workers as compared to the standard
composition or mix.

 It can be calculated in the following two situation:

(a)When the totals of standard labour mix and actual labour mix
are same, but the two mix ratios are different.
(b)When the totals of standard labour mix and actual labour mix
are different, and the two mix ratios are also different.

34
 Situation A
Labour mix variance = (Standard time mix – Actual
time mix) × Standard rate per hour

Situation B
Labour mix variance = (Revised standard time – Actual
time) × Standard rate per hour
Here, RST= Total actual time ×

35
36
 Variable overhead variance
Difference between the standard variable overheads and
absorbed variable overheads is called variable overhead
variance.
If variable overhead absorbed to actual output is more or
less than its standard variable overhead, this variance is
created.
Overhead variance is the difference between the amount
calculated at standard rate of variable overhead and the
amount calculated at actual rate of variable overhead on
the on the actual output.

37
 Variable overhead variance = AO (SR – AR)
= (AO × SR) – (AO × AR)
= SVO – AVO

Here, AO = Actual output, SR = Standard rate,

AR = Actual rate,
SVO = Standard variable overhead, and
AVO = Actual variable overhead

38
Net or overall variable overhead variance
Variable overhead variance =
[Standard hours × Standard variable overhead rate per hour]
– [Actual hours × Actual variable overhead rate per hour]
= [SH × SVOR] – [AH × AVOR]

This net variable overhead variance can be decomposed into

following two variances:
(a)Variable overhead spending variance
(b)Variable overhead efficiency variance

39
 Variable overhead spending variance (VOSV)
VOSV = (Actual hours × Standard variable
overhead rate per hour)
- (Actual hours × Actual variable
overhead rate per hour)

Variable overhead efficiency variance (VOEV) :

The difference between the actual hours used to complete a
job and the standard hours allowed to do it indicates the
efficiency or inefficiency.
It measures the extent of cost saved or excess cost incurred
due to efficient or inefficient performance.

40
 VOEV = (Standard hours allowed for actual volume or
output –
Actual hours taken for actual volume) ×
Standard variable overhead rate per hour

= (Actual output hours × Standard per unit) –

(Actual hours × Standard variable overhead
recovery rate)

The variable overhead can be attributed to the causes

which are responsible for the labour efficiency variance.
Factors such as workers’ personal problems, incentive
plans, work process, frequency and quantity of
machine repairs, materials quantity, etc. will cause
variable overhead efficiency variance.
41
 Variable overhead expenditure variance
Variable overhead expenditure variance =
Budgeted variable overheads – Actual variable overheads

42
 Fixed overhead variance
Fixed overhead variance is mainly concerned with over –
absorption or under – absorption on fixed overheads.
As the fixed overheads are not affected by the volume of
output, its absorption is done on actual output the
predetermined rate only.
Fixed overhead variance is caused due to the difference
between standard fixed overhead and actual fixed overhead
on actual output.
Fixed overhead variance = TSC – TAC
[AO × SFO] – [ AO × AFO]
TSO – TAO
43
 Here, TSC = Total standard cost for actual
output,
TAC = Total actual cost,
AO = Actual output
SFO = Standard fixed overhead
AFO = Actual fixed overhead
TSO = Total standard overhead
TAO = Total actual overhead

44
 Expenditure Variance
The difference between the amount actually spent during a
certain period as fixed overhead and the amount of fixed
overhead budgeted for the period is expressed by this
variance.
This part of fixed overhead cost variance shows whether
the actual amount of fixed overhead is less or more than
the amount budgeted for it.

Expenditure variance =
Budgeted fixed overhead – Actual fixed overhead

45
 Volume variance
Volume variance is caused mainly due to the
difference between budgeted output and actual
output.
To calculate this variance, the difference of budgeted
output and actual output is multiplied by the budgeted
standard absorption rate.

Volume variance = SC (AQ – BQ)

Where, SC = Standard cost per unit of fixed overheads
AQ = Actual output in actual hours worked
BQ = Budgeted standard output in budgeted
standard hours
46
 Efficiency variance
This variance gives information about the efficiency of
workers because it arises due to their being less or more
efficient.
It also arises due to the change in production process or
quality of material and efficiency of the machinery, plant,
and workers.

Efficiency variance = SC (AQ – SQ)

Here, SQ means the quantity produced during actual
working hours at the standard rate.

47
 Capacity variance
Capacity is expressed in terms of average direct labour
hours per day.
If capacity is utilized to a level less or more than the
planned standard, variance arises.
Use of plant and instruments less or more than their
capacity affects the efficiency due to which this variance
arises.

Capacity variance = SC (SQ – BQ)

48
 Calendar variance
If the number of actual working days during a certain
period is different from the standard number of working
days during the same period, then it is called calendar
variance.

Calendar variance = SC (RBQ – BQ)

Here, RBQ = Budgeted quantity of output for actual
working days.

49
 Note:
If the calendar variance is being calculated, capacity
variance should be ascertained using the formula given
below:

Capacity variance = SC (SQ – RBQ)

50
51
 Sales Value Variance
It is the difference between the standard value and the actual
value of sales affected during a period.

Sales value variance =

Actual value of sales – Standard value of sales

52
 Sales price variance
It is the portion of the sales value variance which is due to
the difference between actual price and standard price
specified.

Sales price variance =

Actual quantity sold × (Actual price – Standard price)

53
 Sales Volume Variance
It is the portion of the sales value variance which is due to
the difference between actual quantity of sales and standard
quantity of sales.

Sales Volume Variance = Standard price × (Actual quantity

of sales – Standard quantity of sales)

54
 Sales mix variance :
 It is the part of the sales volume variance and it arises due to
the difference in the proportion in which various articles are
sold and standard proportion in which various articles were
to be sold.
 Sales mix variance = Standard value of actual mix –
Standard value of revised standard mix

Sales Sub – Volume Variance :

 This represents the difference between the budgeted sales. It
is also called as sales quantity variance.
Sales Sub – Volume Variance = (Revised standard sales
quantity × Standard selling price) – (Standard sales
55 quantity × Standard selling price)
 Variances Based On Profits
Total sales margin variance :
This is an overall or composite variance made of other sub-
variances, and is represented by the difference between the
standard margin appropriate to the quantity of sales
budgeted for a period and the margin between standard cost
and actual selling price of the sales affected.

 Total sales margin variance =

Standard or Budgeted margin – Actual margin

56
 Sales margin variance due to the selling
price
This is that portion of total margin variance which is due to
the difference between the standard price on the quantity
of sales affected and the actual price of those sales.

Sales price variance =

(Actual quantity of sales × Standard price) –
(Actual quantity of sales × Actual price)
or
Sales price variance =
Profit on actual sales at standard price and standard cost
– Actual profit
57
 Sales margin variance
due to the volume of
sales
This is that portion of total margin variance which is due to
the difference between the budgeted quantity and the
actual quantity of sales.
The variance is composed of two sub-variances, due to
change in the ratio of quantities of sales (mix variance) and
actual being more or less than the budgeted sales (quantity
variance).

Sales volume variance = Standard profit on standard

quantity of sales – Standard profit on actual quantity
of sales
or
Sales volume variance = Standard profit – profit on
actual sales at standard price and standard costs
58
 Sales margin variance
due to sales mixture
This is that portion of total margin variance which is
due to the difference between the budgeted and
actual quantities of each product of which the sales
mixture is composed, valuing sales standard net
selling prices and cost of sales at standard.

Sales mixture variance = Standard margin ×

(Standard proportion for actual sales – Actual
proportion)
or
Sales mixture variance = Standard sales unit ×
(weighted budgeted margin per unit – Margin of
actual sales units at standard price)
59
 Sales margin variance due to sales
quantities
This is that portion of the sales volume
variance which arises due to the difference in
the total actual and the budgeted sales.

Sales quantity variance = Standard

margin × (Budgeted sales – Standard
proportion for actual sales)

60
61
 Efficiency ratio
Efficiency ratio is the standard hour’s equivalent to the
work produced, expressed as percentage of the actual hours
spent in producing that work.
This is related to the labour efficiency and variable
overheads/fixed overheads efficiency variance
