Marginal Costing
Marginal Costing is a costing technique wherein
the marginal cost, i.e. variable cost is charged to units
of cost, while the fixed cost for the period is completely
written off against the contribution.
The term marginal cost implies the additional
cost involved in producing an extra unit of output,
which can be reckoned by total variable cost assigned
to one unit.
Calculation of Marginal Cost
Characteristics of Marginal Costing
Marginal Costing Absorption Costing
1. Meaning
Marginal costing is a
technique that assumes
only variable costs as
product costs.
Absorption costing is a
technique that assumes
both fixed costs and
variables costs as product
costs.
2. What it’s all
about?
Variable cost is
considered as product
cost and fixed cost is
assumed as cost for the
period.
Both fixed cost and
variable cost are
considered in product
cost.
3. Nature of
overheads
Fixed costs and variable costs.
Overheads in the case of
absorption costing are quite
different – production,
distribution, and selling &
administration.
4. How profit is
calculated?
By using profit volume ratio
(P/V ratio)
Fixed costs are considered in
product costs; that’s why
profit gets reduced.
5. Determines The cost of the next unit. The cost of each unit.
6. Opening &
Closing stocks
Since the emphasis is on the
next unit, change in opening/
closing stocks doesn’t affect
the cost per unit
Since the emphasis is on each
unit, change in
opening/closing stocks affects
the cost per unit.
7. Most important
aspect
Contribution per unit. Net profit per unit
8. Purpose
To show forth the emphasis
of contribution in product
cost.
To show forth the accuracy
and fair treatment of
product cost.
9. How it is
presented?
It is presented by outlining
the total contribution.
It is presented in the most
conventional way for the
purpose of financial and tax
reporting.
Formulas used in Marginal Costing:
Sales — Variable cost + Fixed cost + Profit
Sales – Variable cost = Contribution
Sales – Variable cost = Fixed cost + Profit
Contribution = Fixed cost + Profit
Contribution – Fixed cost = Profit
A variable cost is a corporate expense that
changes in proportion to production output.
Variable costs increase or decrease depending on
a company's production volume; they rise as
production increases and fall as production decreases.
Examples of variable costs include the costs of
raw materials and packaging.
Profit planning is the set of actions taken to
achieve a targeted profit level.
These actions involve the development of an
interlocking set of budgets that roll up into a
master budget
A break-even analysis is a financial tool which helps you
to determine at what stage your company, or a new service or a
product, will be profitable.
In other words, it’s a financial calculation for
determining the number of products or services a company
should sell to cover its costs (particularly fixed costs).
Break-even is a situation where you are neither making
money nor losing money, but all your costs have been covered.
Break-even analysis is useful in studying the relation
between the variable cost, fixed cost and revenue.
Cost-volume-profit (CVP) analysis is used to
determine how changes in costs and volume affect
a company's operating income and net income.
In performing this analysis, there are several
assumptions made, including:
Sales price per unit is constant.
Variable costs per unit are constant.
Total fixed costs are constant.
