Difference between absorption
and marginal costing

Absorption costing Marginal costing
Treatment for
fixed
manufacturing
overheads
Fixed
manufacturing
overheads are
treated as product
costing. It is
believed that
products cannot be
produced without
the resources
provided by fixed
manufacturing
overheads
Fixed manufacturing
overhead are treated
as period costs. It is
believed that only the
variable costs are
relevant to decision-
making.
Fixed manufacturing
overheads will be
incurred regardless
there is production or
not
www.cssfounder.com

8. 8
Absorption costing Marginal costing
Value of
closing stock
High value of
closing stock will be
obtained as some
factory overheads
are included as
product costs and
carried forward as
closing stock
Lower value of
closing stock that
included the variable
cost only
www.cssfounder.com

9. 9
Absorption costing Marginal costing
Reported
profit
If the production = Sales, AC profit = MC Profit
If Production > Sales, AC profit > MC profit
As some factory overhead will be deferred as
product costs under the absorption costing
If Production < Sales, AC profit < MC profit
As the previously deferred factory overhead
will be released and charged as cost of goods
sold
www.cssfounder.com

10. 10
Argument for absorption costing
www.cssfounder.com

11. 11
• Compliance with the generally accepted accounting
principles
• Importance of fixed overheads for production
• Avoidance of fictitious profit or loss
– During the period of high sales, the production is small
than the sales, a smaller number of fixed manufacturing
overheads are charged and a higher net profit will be
obtained under marginal costing
– Absorption costing is better in avoiding the fluctuation of
profit being reported in marginal costing
www.cssfounder.com

12. 12
Arguments for marginal costing
www.cssfounder.com

13. 13
• More relevance to decision-making
• Avoidance of profit manipulation
– Marginal costing can avoid profit manipulation by
adjusting the stock level
• Consideration given to fixed cost
– In fact, marginal costing does not ignore fixed costs in
setting the selling price. On the contrary, it provides useful
information for break-even analysis that indicates whether
fixed costs can be converted with the change in sales
volume
www.cssfounder.com

14. 14
Break-even analysis
www.cssfounder.com

15. 15
Definition
• Breakeven analysis is also known as cost-
volume profit analysis
• Breakeven analysis is the study of the
relationship between selling prices, sales
volumes, fixed costs, variable costs and profits
at various levels of activity
www.cssfounder.com

16. 16
Application
• Breakeven analysis can be used to determine
a company’s breakeven point (BEP)
• Breakeven point is a level of activity at which
the total revenue is equal to the total costs
• At this level, the company makes no profit
www.cssfounder.com

17. 17
Assumption of breakeven point
analysis
• Relevant range
– The relevant range is the range of an activity over which
the fixed cost will remain fixed in total and the variable
cost per unit will remain constant
• Fixed cost
– Total fixed cost are assumed to be constant in total
• Variable cost
– Total variable cost will increase with increasing number of
units produced
www.cssfounder.com

18. 18
• Sales revenue
– The total revenue will increase with the increasing
number of units produced

23. 23
Calculation method
• Contribution is defined as the excess of sales
revenue over the variable costs
• The total contribution is equal to total fixed
cost

Example
• Selling price per unit $12
• Variable cost per unit $3
• Fixed costs $45000
Required:
– Compute the breakeven point
www.cssfounder.com

27. 27
Breakeven point in units = Fixed costs
Contribution per unit
= $45000
$12-$3
= 5000 units
Sales revenue at breakeven point = $12 * 5000 = $60000
www.cssfounder.com

28. 28
Alternative method
Contribution to sales ratio $9 /$12 *100% = 75%
Sales revenue at breakeven point
= Contribution required to break even
Contribution to sales ratio
= $45000
75%
= $60000
Breakeven point in units = $60000/$12 = 5000 units

Example
• Selling price per unit $12
• Variable cost per unit $3
• Fixed costs $45000
• Target profit $18000
Required:
– Compute the sales volume required to achieve the
target profit
www.cssfounder.com

32. 32
No. of units at target profit
Fixed cost + Target profit
Contribution per unit
=
$45000 + $18000
$12 - $3
=
= 7000 units
Required to sales revenue = $12 *7000
= $84000

33. 33
Alternative method
Required sales revenue
Fixed cost + Target profit
Contribution to sales ratio
=
$45000 + $18000

=
= $84000
Units sold at target profit = $84000 /$12 = 7000 units

Margin of safety
www.cssfounder.com

35. 35
Margin of safety
• Margin of safety is a measure of amount by
which the sales may decrease before a
company suffers a loss.
• This can be expressed as a number of units or
a percentage of sales
www.cssfounder.com

36. 36
Formula
Margin of safety
= Margin of safety
Budget sales level *100%
Margin of safety
= Budget sales level – breakeven sales level

38. 38
Example
• The breakeven sales level is at 5000 units. The
company sets the target profit at $18000 and
the budget sales level at 7000 units
Required:
Calculate the margin of safety in units and
express it as a percentage of the budgeted
sales revenue
www.cssfounder.com

39. 39
Margin of safety
= Budget sales level – breakeven sales level
= 7000 units – 5000 units
= 2000 units
Margin of safety
= Margin of safety
Budget sales level
= 2000
7000
= 28.6%
*100 %
*100 %
The margin of safety indicates that the actual sales can fall by
2000 units or 28.6% from the budgeted level before losses are
incurred.

Changes in components of
breakeven point
www.cssfounder.com

41. 41
Example
• Selling price per unit $12
• Variable price per unit $3
• Fixed costs $45000
• Current profit $18000
www.cssfounder.com

42. 42
• If the selling prices is raised from $12 to
$13, the minimum volume of sales required
to maintain the current profit will be:
Fixed cost + Target profit
Contribution to sales ratio
=
$45000 + $18000
$13 - $3
= 6300 units
www.cssfounder.com

43. 43
• If the fixed cost fall by $5000 but the variable
costs rise to $4 per unit, the minimum volume
of sales required to maintain the current profit
will be:
Fixed cost + Target profit
Contribution to sales ratio
=
$40000 + $18000
$12 - $4
= 7250 units
www.cssfounder.com

44. 44
Limitation of breakeven point
www.cssfounder.com

45. 45
Limitations of breakeven analysis
• Breakeven analysis assumes that fixed cost,
variable costs and sales revenue behave in
linear manner. However, some overhead costs
may be stepped in nature. The straight sales
revenue line and total cost line tent to curve
beyond certain level of production
www.cssfounder.com

46. 46
• It is assumed that all production is sold. The
breakeven chart does not take the changes in
stock level into account
• Breakeven analysis can provide information
for small and relatively simple companies that
produce same product. It is not useful for the
companies producing multiple products
