MARGINAL COSTING
The basic objectives of Cost Accounting are cost ascertainment and cost control
...
Marginal costing
and Break even analysis are important techniques used for cost control and decision nmaking
...
It is the

addition made to total cost when the output is increased by one unit
...

Marginal cost of nth unit = Total cost of nth unit- total cost
Eg
...
5000
...
e, 101

of n-1

units, total cost is Rs
...
Then marginal cost of 101th unit is Rs
...
The chartered Institute of Management Accountants [CIMA] England defines Marginal as "the amount

atany

given volume of output by which aggregate costs are changed if the volume of output is increased or

decreased by one unit

MARGINAL COSTING
It is the technique of costing in which only marginal costs or variable are charged to output or production
...
Fixed costs are not charged to output
...
Therefore, these fixed costs are directly transferred to Costing Profit and Loss

Sales-Variable Cost = Contribution

Contribution = Fixed costs + Proit

Therefore, Fixed cost = Contribution-Profit

Fixed costs are transferred to costing profit and

It also prevents the illegal carry forward in stock valuation of some proportion of current years fixed cost

BREAK EVEN ANALYSIS
Every business is interested in ascertaining the breakeven point
...
It is the point of no profit or no loss
...
The firm ceases to incur losses at this point or it
starts to earn a profit from this point
...

Breakeven point in Value
Given:

Selling price per unit Rs
...
12

Fixed costs Rs
...
PV Ratio = Contribution/Sales x 100=20-12/20x100 = 40 %

...
Breakeven point in value = Fixed costs = 32000/40 x100 = Rs
...
The fim can decide upon the target return or profit in advance
...
The volume of sales required to achieve the desired level of profit may be
computed as follows -

Number of units to be sold = Fixed costs + desired Profiv Contribution per unit
Sales volume required = Fixed costs+ Desired Profits/ P/V Ratio
