3. MARGINAL COSTING
Marginal Costing is not a system of costing such a
Job Costing and Process Costing. Marginal Costing
is the cost of producing one extra unit of the
output.
Marginal costing is helpful for industries to perform
the functions like profit planning, cost control and
decision-making.
Marginal costing basically concern with the
determination of product cost, which consist of
TOTAL COST- FIXED COST
e.g. Direct Material, Direct Labour, Direct Expenses
and Variable Overheads.

5. DEFINITIONS OF MARGINAL COSTING
ICMA London- “The ascertainment of marginal cost
by differentiating between fixed and variable cost
and of the effect of profit or changes in volume or
type of output”.
“The ascertainment of marginal cost, of the effect
on profit of changes in volume or types of output”.
6. FORMULA
Marginal Cost = Variable Cost
Hence, Marginal Cost = Direct Material+ Direct Labour+ Direct
Expenses+ Variable Overheads.
In brief,
Marginal Cost = Prime Cost + Variable Overhead.
Similarly, Sales = Variable Cost + Fixed Cost + Profit
(if loss less)
So, Sales = Variable Cost + Fixed Cost + Profit
But, by marginal costing,
Sales – Variable Cost = Contribution
Again,
Contribution – Fixed Cost = Profit
Hence, Contribution = Fixed Cost + Profit
7. CONTRIBUTION
Contribution is the excess of selling price over
variable cost. It is known as contribution, because it
contributes towards recovery of the fix cost and
profit.
Contribution= Sales – Variable Cost
OR
Contribution = Fixed Cost + Profit
8. IMPORTANT POINTS OF CONTRIBUTION
Contribution is not a profit.
It covers fixed cost and balance
left out is profit.
Plays important role in decision-
making.
10. PROFIT / VOLUME RATIO (P/V RATIO)
It expresses the relationship between
contribution and sales.
P/V Ratio is most important to watch in business.
It is the indicator of rate at which the organization
is earning profit.
A high ratio indicates high profitability and low
ratio indicates low profitability.
Uses:-
1. For calculation of Break- Even point.
2. Profit at a given level of sales.
3. Sales required to earn a certain amount of profit.
11. FORMULA FOR P/V RATIO

This ratio is always expressed in percentage.

13. BREAK – EVEN POINT [BEP]
Break- Even Point is the point at which total
revenue is equal to total cost.
It is that level of output (sale) where there is
situation like no profit or no loss.
TR=TC
At this stage contribution is just sufficient to absorb
fixed cost. The organization starts earning profit
when output activity crosses this point.

17. ASSUMPTIONS OF BEP
Break-Even Analysis is based on the following
assumptions:-
Market is sufficient to absorb the entire output.
Cost
• Classified as
• Fixed and variable categories
Fixed Cost
• Remains fix
• For entire volume
Selling per
unit
• Remains same
• For entire volume
18. USES OF BEP
Facilitate determination of selling price which will
give desired profits.
Makes possible to divide the sale volume to cover a
given rate of return on cash employed.
Used for management for forecast profit and
volume at level of activity.
Suggest to make a change in sales mixed.
Helps management to do interfirm comparison of
profitability
Shows the impact of changes in cost on profit.
Enables management to plan for optimum
utilisation of the capacity.
20. LIMITATIONS OF BEP
Break- Even Analysis is the subject to certain
limitations which are as follows:-
BEP is based on the assumptions that cost can be
classified into fixed and variable categories. In
practice, it is very difficult to have such a clear- cut
distinct between fix and variable cost. These costs
which cannot be classified accordingly.
BEP indicates a static picture. It becomes out of
date if, there is a change in the assumptions or
conditions.
21. LIMITATIONS OF BEP
Company manufacturing variety of product cannot
represent the fact of each product in the chart.
Break – Even Chart does not considered the
amount of capital employed which is very vital in
many decisions.
In a practice, assumption and fixed cost remains
constant, may not hold true.
Selling price may not remain constant.
Variable cost may not vary in direct proportion to
the volume.
23. MARGIN OF SAFETY
It shows that BEP is much below the actual
sales. In this cases if there is a fall in the sales
there will still be profit but if the margin of safety is
low, any reducing in sales will be of agrave concern
for the company.
The fixed cost are recovered up to the Break Even
Point [BEP].
Hence, all the contribution after BEP (sales)
amount at profit. Margin of safety is always
related to profit.
25. FORMULA FOR MARGIN OF SAFETY
Selling Price < Total Cost = Loss.
Selling Price > Total Cost = Profit.
Profit = Margin of Safety × P/V Ratio.
Margin of Safety =
𝑃𝑟𝑜𝑓𝑖𝑡
𝑃/𝑉𝑅𝑎𝑡𝑖𝑜
26. EXAMPLE
If profit is 25%, PV Ratio is 50%
Margin of Safety =
𝑃𝑟𝑜𝑓𝑖𝑡
𝑃/𝑉𝑅𝑎𝑡𝑖𝑜
=
25
50
× 100
= 50
27. When the Margin of Safety is not satisfactory the
following steps become necessary:-
1. Reduction of Fixed Cost.
2. Reduction of Variable Cost.
3. Increasing the Selling Price.
4. Increasing the Sales Volume.
5. Improving the contribution by changing the sales
mix.

40. EXPLANATION
It is formed by intersection of sales line and total
cost line at the BEP.
Shows rate of organization of earning profit.
Wider the angle, greater is the rate of earning profit
with increase in sales.
Large angle of incidence greater margin of safety
shows extremely favorable situations.
Hence, efforts are made to increase this angle as
wide as possible by the management. It shows high
margin of safety and best business position.

42. The objective of any organization is to earn profit. It
depends upon a large number of factors, but mostly on
cost of manufacture and volume of sales effected.
Cost is affected by :-
Volume of Production.
Production mix.
Internal Efficiency.
Methods of Production.
Size of Plant.
These factors volume is most significant which
influences greater on cost.
43. Cost is divided into two categories they are fixed cost and
variable cost. Volume is affected by many factors. There
are some outside factors which are beyond the control of
management. Profits are affected by cost and volume
both.
Cost – volume profit analysis shows the picture of profits
at various levels of production activities such as purchases
of raw materials, work in progress and sales, etc.
It distinguishes between the impact of sales fluctuations
and results of price of cost upon profit i.e.
𝐶
𝑃
.
It enables the management to understand the change in
profit in a relation of output and sales.
44. Volume is expressed in terms of sales capacity i.e. percentage
of maximum sales,
value of sales,
unit of sales.
Production capacity is expressed in terms of
percentage of maximum production,
production in physical terms,
direct labour hours and
machine hours.
C- VP analysis involves consideration of the following factors:-
1. Volume of Sales.
2. Selling Price.
3. Product Mix.
4. Variable Cost per unit.
5. Total Fixed cost.
46. KEY FACTOR
We studied under marginal costing, that the
profitability of a proposal is in terms of its
contribution.
For maximization of profit, the firm would imply all
its resources and produce that quantity which will
give maximum contribution to profit. (i.e. Use of
optimum resources).
Constraints are faced by organization daily in
production process, such constraints / problems are
called as limited constraints.
