Variance Analysis
Variance Analysis
Control can be
said to be of 3 steps:-
ß Establishment
of Standards.
ß Evaluation
of Activity.
ß Taking
Corrective Action (if any).
The first step
has given rise to the concept of standard costing.
Standard costing can be applied to any facet
of management especially in relation to production and labour & over
head cost.
Standard recipe, standard food cost,
standard yield, standard man-hours, time & motion study, are all
outcomes of standard costing,
Standard costing
is also known as pre-costing i.e. costing before the event.
When actual operation is undertaken i.e.
the second step which is evaluation of activity there are some
variations which happen which in management terms is termed as variances. Variances can be Adverse and Favourable.
This analysis and taking corrective action
is the management function which is known as Variance Analysis.
Any cost function which can be
budgeted can be subjected to Variance Analysis viz.:-
ß Sales.
ß Marketing.
ß Labour.
ß Material.
ß Overhead.
ß Profit.
Material
Variance can be classified into:-
Material Price
Variance
This type of variance occurs when the
materials are supplied at different prices over a period (accounting cycle).
This type of price variance does not occur much in hotels where tender purchase
is followed and food materials are supplied at a uniform price over a period of
time.
The
mathematical calculation is as follows:-
(Standard
Price - Actual Price) X Actual Quantity
Material Usage
Variance
This type of Variance is very common in hotel
operations, as much of the materials are fabricated by human beings who are
more susceptible to errors. (In other organized industries a lot of machines
are used for fabricating materials).
The
mathematical calculation is as follows:-
(Standard
Material - Actual Material used) X Actual Price.
Labour
variance can be classified as under:
1)
Labour rate variance
: is the difference between the standard and actual rate of pay, multiplied by
the actual hours.
The formula being (Standard
rate-Actual rate) X actual hours worked.
2)
Labour efficiency variance
: is due to actual efficiency being different from that expected and is
calculated as the difference between actual hours worked and the hours which
should have been worked to produce the actual output.
The formula is (Standard hours of
actual output – Actual hours) X Standard rate.
Overhead
variances are as follows
1) Over head variance is the
difference between standard overhead cost for actual output and the actual
overhead cost incurred.
The formula for computing the variance is
as follows: Overhead recovered –Actual Overhead.
2) Fixed overhead Variance is the
difference between the standard fixed overhead for actual output and the actual
fixed overhead incurred.
The formula is as follows: Fixed overhead
recovered –Actual over head.
Sales
Variance
The technique of variance analysis can be
effectively used for the purpose of analyzing sales variance. Sales variance
can be used to identify the reasons for divergence between budgeted and actual
performance so that adequate control measures may be taken.
There are two methods for calculating
sales variances:
1) On the basis of turn over (sales) and
the formula is : Budgeted sales - Actual sales.
2) On the basis of profit margin and the
formula is : Budgeted profit – Actual profit.
As far as F &. B
Operation is concerned we are mainly concerned about Material Variance
which is food material.
Similarly labour and overhead variances
could be calculated and analysed but strictly it is an area of the Human
Resource Department (Labour) & Maintenance Department (Overhead). In small
organizations it may be handled by the Sectional Manager also.
Advantages of Variance Analysis or
Standard Costing
ß It
gives a standard for measurement.
ß It
gives an objective to be achieved.
ß It
has given birth to the concepts of:
1.
Standard Purchase Specification
2.
Standard Recipe
3.
Standard yield
4.
Standard Portion Cost
Disadvantages of Variance Analysis /
Standard Cost
ß Discourages
Creativity. Expensive and time consuming.
ß Cannot
be accurately measured in multi-product operations where the same ingredient is
used in many products.
ß It
is a step done after the job where rectification is only possible for future
events.
ß Unutilized
portions of food cannot be effectively reutilized.
