SU- 8.1 – Cost-Volume-Profit (CVP) Analysis Theory
• CVP = Break-even analysis
– Allows us to analyze the relationship between revenue and fixed and
variable expenses
– It allows us to study the effects of changes in assumptions about cost
behavior and the relevant ranges (in which those assumption are
valid) may affect the relationships among revenues, variable costs, and
fixed costs at various production levels
– Cost-volume-profit analysis is a tool to predict how changes in costs
and sales levels affect income; conventional CVP analysis requires that
all costs must be classified as either fixed or variable with respect to
production or sales volume before CVP analysis can be used.
– It considers the effects of:
•
•
•
•
Sales volume
Sales price
Product mixes
What else……?
SU- 8.1 – Cost-Volume-Profit (CVP) Analysis Theory
• CVP analysis is done with what assumptions?
– Cost and revenue relationships are predictable
– Unit selling prices are constant
– Changes in inventory are insignificant
– Fixed costs remain constant over relevant range
(see slide 5 & 6)
– Total variable cost change proportional with
volume (see slide 7 & 8)
Continued
SU- 8.1 – Cost-Volume-Profit (CVP) Analysis Theory
– The revenue (sales) mix is constant
– All costs are either fixed or variable (long-term all
costs are considered as variable)
– Volume is the sole revenue driver and cost driver
– The breakeven point is directly related to costs
and inversely related to the budgeted margin of
safety and the contribution margin
– Time value of money is ignored
SU- 8.1 – Cost-Volume-Profit (CVP)
Analysis – Theory – Fixed Costs
• Fixed Costs
– Total fixed cost remains unchanged in amount when volume of activity
varies from period to period within a relevant range.
– The fixed cost per unit of output decreases as volume increases (and
vice versa).
– When production volume and cost are graphed, units of product are
usually plotted on the Horizontal axis and dollars of cost are plotted on
the vertical axis.
– Fixed cost is represented by a horizontal line with no slope (cost
remains constant at all levels of volume within the relevant range).
– Intersection point of line on cost (vertical) axis is at fixed cost amount.
– Likely that amount of fixed cost will change when outside of relevant
range.

Analysis – Theory – Variable Costs
• Variable Costs
– Total variable cost changes in proportion to changes in
volume of activity.
– Variable cost per unit remains constant but the total
amount of variable cost changes with the level of
production.
– When production volume and cost are graphed
– Variable cost is represented by a straight line starting
at the zero cost level.
– The straight line is upward (positive) sloping. The line
rises as volume increases.

Analysis – Theory – Mixed Costs
• Mixed Costs
– Include both fixed and variable cost components.
– When volume and cost are graphed,
• Mixed cost is represented by a straight line with an upward
(positive) slope.
• Start of line is at fixed cost point (or amount of total cost
when volume is zero) on cost (vertical) axis. As activity level
increases, mixed cost line increases at an amount equal to
the variable cost per unit.
– Mixed costs are often separated into fixed and
variable components when included in a CVP analysis.

– Mixed costs – (See slide 11) Costs that have both a fixed and variable
component. For example, the cost of operating an automobile includes some
fixed costs that do not change with the number of miles driven (e.g., operating
license, insurance, parking, some of the depreciation, etc.) Other costs vary
with the number of miles driven (e.g., gasoline, oil changes, tire wear, etc.).
– Revenue or sales mix is the composition of total revenues in terms of various
products
– Sensitivity analysis – (See slide 12) Examines the effect on the outcome of not
achieving the original forecast or of changing an assumption. Since many
decisions must be made due to uncertainty, probabilities can be assigned to
different outcomes (“what-if”).

Theory - Question 1
Question 1 - CMA2 Study Unit 8: CVP
Analysis and Marginal Analysis
Cost-volume-profit (CVP) analysis is a key
factor in many decisions, including choice of
product lines, pricing of products, marketing
strategy, and use of productive facilities. A
calculation used in a CVP analysis is the
breakeven point. Once the breakeven point
has been reached, operating income will
increase by the
A.
B.
C.
D.
Gross margin per unit for each additional unit
sold.
Contribution margin per unit for each
additional unit sold.
Fixed costs per unit for each additional unit
sold.
Variable costs per unit for each additional unit
sold.
SU- 8.1 – Cost-Volume-Profit (CVP) Analysis –
Theory – Answer to Question 1
•
Correct Answer: B
At the breakeven point, total revenue equals total fixed costs plus the variable
costs incurred at that level of production. Beyond the breakeven point, each unit
sale will increase operating income by the unit contribution margin (unit sales
price – unit variable cost) because fixed cost will already have been recovered.
Incorrect Answers:
A: The gross margin equals sales price minus cost of goods sold, including fixed
cost.
C: All fixed costs have been covered at the breakeven point.
D: Operating income will increase by the unit contribution margin, not the unit
variable cost.

SU- 8.1 – Cost-Volume-Profit (CVP) Analysis –
Theory – Answer to Question 2
Correct Answer: C
One of the inherent simplifying assumptions used in CVP analysis is that
fixed costs remain constant over the relevant range of activity.
Incorrect Answers:
A: Breakeven analysis assumes no changes in efficiency and productivity.
B: Total variable costs, by definition, change across the relevant range.
D: The cost of production factors is assumed to be stable; this is what is
meant by relevant range.

the
A.
B.
C.
D.
Contribution margin rate.
Difference between budgeted
contribution margin and breakeven
contribution margin.
Difference between budgeted sales and
breakeven sales.
Difference between the breakeven point

SU- 8.1 – Cost-Volume-Profit (CVP) Analysis –
Theory – Answer to Question 3
Correct Answer: C
The margin of safety measures the amount by which sales may decline
before losses occur. It is the excess of budgeted or actual sales over sales at
the BEP.
Incorrect Answers:
A: The contribution margin rate is computed by dividing contribution
margin by sales. The contribution margin equals sales minus total variable
costs.
B: The margin of safety is expressed in revenue or units, not contribution
margin.
D: Cash flow is not relevant.

SU- 8.1 – Cost-Volume-Profit (CVP) Analysis –
Theory – Answer to Question 4
Correct Answer: A
The breakeven point in units is calculated by dividing total fixed costs by the unit
contribution margin. If selling price is constant and costs increase, the unit
contribution margin will decline, resulting in an increase of the breakeven point.
Incorrect Answers:
B: A decrease in costs will cause the unit contribution margin to increase, lowering
the breakeven point.
C: An increase in the selling price will increase the unit contribution margin,
resulting in a lower breakeven point.
D: Both a cost decrease and a sales price increase will increase the unit
contribution margin, resulting in a lower breakeven point.

A.
A 15% decrease in selling price.
B.
A 15% increase in variable expenses.
C.
A 15% decrease in variable expenses.
D.
A 15% decrease in fixed expenses.
SU 8.2 – Practice Question 1 Answer
• Correct Answer: A
Unit contribution margin (UCM) equals unit
selling price minus unit variable costs. It can be
decreased by either lowering the price or raising
the variable costs. As long as UCM is positive, a
given percentage change in selling price must
have a greater effect than an equal but opposite
percentage change in variable cost. The example
below demonstrates this point.
Continued
SU 8.2 – Practice Question 1 Answer
Original:
UCM = SP – UVC
= $100 – $50
= $50
Lower Selling Price:
UCM = (SP × .85) – UVC
= $85 – $50
= $35
Higher Variable Cost:
UCM = SP – (UVC × 1.15)
= $100 – $57.50
= $42.50
Since $35 < $42.50, the lower selling price has
the greater effect.
SU 8.2 – Practice Question 2
The breakeven point in units sold for Tierson Corporation is
44,000. If fixed costs for Tierson are equal to $880,000 annually
and variable costs are $10 per unit, what is the contribution
margin per unit for Tierson Corporation?
A.
$0.05
B.
$20.00
C.
$44.00
D.
$88.00
SU 8.2 – Practice Question 2 Answer
Correct Answer: B
The breakeven point in units is equal to the fixed
costs divided by the contribution margin per
unit. Thus, the UCM is $20.00 ($880,000 ÷
44,000 units).
SU 8.2 – Practice Question 3
A manufacturer contemplates a change in technology that would
reduce fixed costs from $800,000 to $700,000. However, the
ratio of variable costs to sales will increase from 68% to 80%.
What will happen to breakeven level of revenues?
A.
Decrease by $301,470.50.
B.
Decrease by $500,000.
C.
Decrease by $1,812,500.
D.
Increase by $1,000,000.
SU 8.2 – Practice Question 3 Answer
Correct Answer: D
The original breakeven level was:
Breakeven point = Fixed costs ÷ Contribution margin ratio
= $800,000 ÷ (1.0 – .68)
= $2,500,000
Continued
SU 8.2 – Practice Question 3 Answer
The new level is:
Breakeven point = Fixed costs ÷ Contribution margin ratio
= $700,000 ÷ (1.0 – .80)
= $3,500,000
Thus, there is an increase of $1,000,000 ($3,500,000 –
$2,500,000).

SU 8.3 – Practice Question 3 Answer
Correct Answer: D
Buona Fortuna’s unit contribution margin is $4 ($10 unit price – $6 unit variable cost).
By treating desired profit as an additional fixed cost, the target unit sales can be
calculated as follows:
Target unit sales = (Fixed costs + Target operating income)
÷ UCM
= ($300,000 + $90,000) ÷ $4
= 97,500

D.
Product BD-4 should be produced, yielding a
contribution margin of $250,000.
SU- 8.4 CVP Analysis – Multiproduct Calculations
– Answer to Question 1
Correct Answer: D
The machine hours are a scarce resource that must be allocated to the product(s) in a proportion that
maximizes the total CM. Given that potential additional sales of either product are in excess of production
capacity, only the product with the greater CM per unit of scarce resource should be produced. XY-7 requires
.75 hours; BD-4 requires .2 hours of machine time (given fixed manufacturing cost applied at $1 per machine
hour of $.75 for XY-7 and $.20 for BD-4). XY-7 has a CM of $1.33 per machine hour ($1 UCM ÷ .75 hours), and
BD-4 has a CM of $2.50 per machine hour ($.50 ÷ .2 hours). Thus, only BD-4 should be produced, yielding a
CM of $250,000 (100,000 × $2.50). The key to the analysis is CM per unit of scarce resource.
Incorrect Answers:
A: Product XY-7 actually has a CM of $133,333, which is lower than the $250,000 CM for product BD-4.
B: Product BD-4 has a higher CM at $250,000.
C: Product BD-4 has a CM of $250,000.

– Answer to Question 3
Correct Answer: D
Contribution margin
equals selling price
minus variable costs.
The product contribution margins are:
Racer:
$570 – $200
=
$370
5-Speed:
$180 – $90
=
$90
Racer:
8,000 ÷ (8,000 + 12,000) =
40%
5-Speed:
12,000 ÷ (8,000 +
12,000)
60%
The sales mix is:
Multiply the CM by the sales mix for each product,
and add the results.
Weighted-average CM = ($370 × 40%) + ($90 ×
60%)
= $148 + $54
= $202

– Answer to Question 3
Incorrect Answers:
A: The sales mix dictates how much of the total CM will come from sales
of each product. Unit sales are attributable 40% to racers and 60% to 5speeds, so 40% of the UCM for racers must be added to 60% of the UCM for
5-speeds to get the weighted-average CM.
B: The sales mix dictates how much of the total CM will come from sales
of each product. Unit sales are attributable 40% to racers and 60% to 5speeds, so 40% of the UCM for racers must be added to 60% of the UCM for
5-speeds to get the weighted-average CM.
C: The sales mix dictates how much of the total CM will come from sales
of each product. Unit sales are attributable 40% to racers and 60% to 5speeds, so 40% of the UCM for racers must be added to 60% of the UCM for

Catfur Company has fixed costs of $300,000.
It produces two products, X and Y. Product X
has a variable cost percentage equal to 60%
of its $10 per unit selling price. Product Y
has a variable cost percentage equal to 70%
of its $30 selling price. For the past several
years, sales of Product X have averaged 66%
of the sales of Product Y. That ratio is not
expected to change.

SU- 8.4 CVP Analysis – Multiproduct Calculations
– Answer to Question 4
Correct Answer: D
A helpful approach in a multiproduct situation is to make calculations based on the
composite unit, i.e., 2 units of Product X and 3 units of Product Y (a 66% ratio). The
selling price of this composite unit is $110 [(2 × $10) + (3 × $30)]. The UCM of the
composite unit is $35 {[2 × ($10 – $6)] + [3 × ($30 – $21)]}. Consequently, the
breakeven point in composite units is 8,571.43 ($300,000 FC ÷ $35 UCM), and the
breakeven point in sales dollars is $942,857 (8,571.43 × $110).
Incorrect Answers:
A: This amount equals the fixed costs.
B: This amount assumes a 40% contribution margin ratio.
C: This amount assumes a 35% contribution margin ratio.

Accounting Costs vs. Economic Costs
– Accounting Costs = The total amount of money or goods expended in an endeavor. It is money
paid out at some time in the past and recorded in journal entries and ledgers.
•
Economic Costs = The economic cost of a decision depends on both the cost of the
alternative chosen and the benefit that the best alternative would have provided if
chosen. Economic cost differs from accounting cost because it includes
opportunity cost.
As an example, consider the economic cost of attending college. The accounting cost of attending college
includes tuition, room and board, books, food, and other incidental expenditures while there. The
opportunity cost of college also includes the salary or wage that otherwise could be earning during the
period. So for the two to four years an individual spends in school, the opportunity cost includes the money
that one could have been making at the best possible job. The economic cost of college is the accounting
cost plus the opportunity cost.
Thus, if attending college has a direct cost of $20,000 dollars a year for four years, and the lost wages from
not working during that period equals $25,000 dollars a year, then the total economic cost of going to
college would be $180,000 dollars ($20,000 x 4 years + the interest of $20,000 for 4 years + $25,000 x 4
years).

• Explicit vs. Implicit Costs
– Implicit Costs = implicit cost, also called an
imputed cost, implied cost, or notional cost, is
the opportunity cost equal to what a firm must
give up in order to use factors which it neither
purchases nor hires.
– Explicit Costs = An explicit cost is a direct payment
made to others in the course of running a
business, such as wage, rent and materials.

• Law of Demand - Law of demand states that ' all
other things remaining unchanged, people
demand (buy) more of any good / service if the
price of that good / service falls and demand
(buy) less if the price increases. The law of
demand is usually represented by a negativelysloped demand curve which slows that the
quatity demanded (quantity of a particular good
people intending to buy) declines as price rises
and increases as price rises.

• Elasticity of demand measures how responsive a
products demand is to changes in its price level.
When we have inelastic demand, a consumer will pay
almost any price for the good.
Elastic demand therefore means that demand for the
product will vary when its price changes. Generally
goods which have elastic demand tend to have many
substitutes, so if the price of one good increases too
much I will substitute out towards a similar good which
is cheaper.

Calculating Price elasticity of demand
–
Price elasticity of demand is calculated as the percentage change in quantity demanded divided by
the percentage change in price.
–
There are a number of factors that can determine the price elasticity of demand for a good or
service.
For example, the demand for luxury items tend to be more elastic than the demand for necessities.
For items that are essential, you tend to be less responsive to changes in price. An example of this
would be the demand for diamonds tends to be more price elastic than the demand for electricity.
Price elasticity of demand is also affected how large a percentage of your total income an item is. We
tend to be more elastic in regards to price changes for items that make up a larger percentage of our
incomes. For example, if the price of a pack of gum goes up by 10%, I probably wouldn't even notice.
On the other hand, if the price of a car I'm considering purchasing goes up by 10%, I would definitely
notice and I would probably reconsider the purchase.
A third factor that influences the price elasticity of demand is the time frame allowed for response.
We tend to be more responsive to changes in price in the long run than in the short run. For
example, if the price of gas were to go up overnight to $10/gallon I would still have to put gas in my
car tomorrow morning because I have to go to work and I have to go to school. But if the price of gas
were to stay at $10/gallon for a year, then I have more options. I could move closer to work, start
carpooling, or trade in my car for a hybrid with better gas mileage so that I don't have to buy as much
gas. So in the long run, demand tends to be more elastic than in the short run.

Price elasticity example
Antoinette has a beauty salon. She services 100
customers per day. Her usual fee is $50. She
wants to expand her business. If she lowers her
price (gives everyone a coupon for $10 off), she
expects to get an extra 10 customers per day.
Calculate the price elasticity of demand. Did she
make the correct decision?
SU 8.6 Short-run Profit Maximization
Price elasticity example
• A) Percentage change in quantity demanded = 10% (100 customers
increased to 110 customers)
B) Percentage change in price = -20% ($50 reduced to $40)
A/B = 10%/-20% = -0.5
The price elasticity of demand for this service is -0.5, and a price elasticity
of demand less than 1 means that a good is inelastic, meaning that
quantity demanded is relatively unresponsive to a change in price.
So you could argue that she made the wrong decision, as the price
decrease did not greatly affect demand. She might have been better
choosing another strategy, such as better advertising or her services.
You could also argue that she is reducing the price by 20% in return for a
10% increase in volume.

Price elasticity defined
A product with elasticity of 1.2 has elastic demand. What this means is that
for every 1% rise in the price, demand will fall by 1.2% (similarly, a 1% fall in
the price will lead to a 1.2% rise in demand).
The rule is:
Elasticity > 1 : elastic (% change in demand is greater than % change in price e.g. luxury
goods such as cars etc.)
Elasticity < 1 : inelastic (% change in demand is less than % change in price e.g. essential
goods such as food)
Elasticity = 1 : unitary elastic (% change in demand is equal to the % change in price)
Basically a firm producing an inelastic good can increase revenue by raising the price, as the
fall in demand is more than offset by the increased revenue on the remaining demand.

Price elasticity defined
• Infinite or perfectly elastic - If it were “perfectly” elastic,
demand would be infinite at all prices less than $3. A perfectly
elastic demand graph is a vertical line. And, when the price is
at $3, you can not tell from the graph what the demand is
since the line is vertical. The demand could be at any value.
• Perfectly price inelastic - means that the quantity demanded
will not change when price changes. Vertical demand curve
Also, perfectly price elastic means if price changes, quantity
demanded changes totally, Horizontal Demand Curve
