a. In the contribution-margin approach, the break-even point in units is calculated
using the following formula:
Break-even point 
fixed expenses
unit contribution margin
b. In the equation approach, the following profit equation is used:

 sales price
This equation is solved for the sales volume in units.
c. In the graphical approach, sales revenue and total expenses are graphed. The
break-even point occurs at the intersection of the total revenue and total expense
lines.
7-2
The term unit contribution margin refers to the contribution that each unit of sales
makes toward covering fixed expenses and earning a profit. The unit contribution
margin is defined as the sales price minus the unit variable expense.
7-3
In addition to the break-even point, a CVP graph shows the impact on total expenses,
total revenue, and profit when sales volume changes. The graph shows the sales
volume required to earn a particular target net profit. The firm's profit and loss areas
are also indicated on a CVP graph.
7-4
The safety margin is the amount by which budgeted sales revenue exceeds breakeven sales revenue.
7-5
An increase in the fixed expenses of any enterprise will increase its break-even point.
In a travel agency, more clients must be served before the fixed expenses are
covered by the agency's service fees.
7-6
A decrease in the variable expense per pound of oysters results in an increase in the
contribution margin per pound. This will reduce the company's break-even sales
volume.

The president is correct. A price increase results in a higher unit contribution margin.
An increase in the unit contribution margin causes the break-even point to decline.
The financial vice president's reasoning is flawed. Even though the break-even
point will be lower, the price increase will not necessarily reduce the likelihood of a
loss. Customers will probably be less likely to buy the product at a higher price.
Thus, the firm may be less likely to meet the lower break-even point (at a high price)
than the higher break-even point (at a low price).
7-8
When the sales price and unit variable cost increase by the same amount, the unit
contribution margin remains unchanged. Therefore, the firm's break-even point
remains the same.
7-9
The fixed annual donation will offset some of the museum's fixed expenses. The
reduction in net fixed expenses will reduce the museum's break-even point.
7-10
A profit-volume graph shows the profit to be earned at each level of sales volume.
7-11
The most important assumptions of a cost-volume-profit analysis are as follows:
(a) The behavior of total revenue is linear (straight line) over the relevant range. This
behavior implies that the price of the product or service will not change as sales
volume varies within the relevant range.
(b) The behavior of total expenses is linear (straight line) over the relevant range.
This behavior implies the following more specific assumptions:
(1) Expenses can be categorized as fixed, variable, or semivariable.
(2) Efficiency and productivity are constant.
(c) In multiproduct organizations, the sales mix remains constant over the relevant
range.
(d) In manufacturing firms, the inventory levels at the beginning and end of the
period are the same.
7-12
Operating managers frequently prefer the contribution income statement because it
separates fixed and variable costs. This format makes cost-volume-profit
relationships more readily discernible.

The gross margin is defined as sales revenue minus all variable and fixed
manufacturing expenses. The total contribution margin is defined as sales revenue
minus all variable expenses, including manufacturing, selling, and administrative
expenses.
7-14
East Company, which is highly automated, will have a cost structure dominated by
fixed costs. West Company's cost structure will include a larger proportion of
variable costs than East Company's cost structure.
A firm's operating leverage factor, at a particular sales volume, is defined as its
total contribution margin divided by its operating income. Since East Company has
proportionately higher fixed costs, it will have a proportionately higher total
contribution margin. Therefore, East Company's operating leverage factor will be
higher.
7-15
When sales volume increases, Company X will have a higher percentage increase in
operating than Company Y. Company X's higher proportion of fixed costs gives the
firm a higher operating leverage factor. The company's percentage increase in
operating income can be found by multiplying the percentage increase in sales
volume by the firm's operating leverage factor.
7-16
The sales mix of a multiproduct organization is the relative proportion of sales of its
products.
The weighted-average unit contribution margin is the average of the unit
contribution margins for a firm's several products, with each product's contribution
margin weighted by the relative proportion of that product's sales.
7-17
The car rental agency's sales mix is the relative proportion of its rental business
associated with each of the three types of automobiles: subcompact, compact, and
full-size. In a multi-product CVP analysis, the sales mix is assumed to be constant
over the relevant range of activity.
7-18
Cost-volume-profit analysis shows the effect on profit of changes in expenses, sales
prices, and sales mix. A change in the hotel's room rate (price) will change the
hotel's unit contribution margin. This contribution-margin change will alter the
relationship between volume and profit.

Budgeting begins with a sales forecast. Cost-volume-profit analysis can be used to
determine the profit that will be achieved at the budgeted sales volume. A CVP
analysis also shows how profit will change if the sales volume deviates from
budgeted sales.
Cost-volume-profit analysis can be used to show the effect on profit when
variable or fixed expenses change. The effect on profit of changes in variable or
fixed advertising expenses is one factor that management would consider in making
a decision about advertising.
7-20
The low-price company must have a larger sales volume than the high-price
company. By spreading its fixed expense across a larger sales volume, the low-price
firm can afford to charge a lower price and still earn the same profit as the high-price
company. Suppose, for example, that companies A and B have the following
expenses, sales prices, sales volumes, and profits.
Company A
Sales revenue:
350 units at $10 ..............................................
100 units at $20 ..............................................
Variable expenses:
350 units at $6 ................................................
100 units at $6 ................................................

The statement makes three assertions, but only two of them are true. Thus the
statement is false. A company with an advanced manufacturing environment
typically will have a larger proportion of fixed costs in its cost structure. This will
result in a higher break-even point and greater operating leverage. However, the
firm's higher break-even point will result in a reduced safety margin.
7-22
Activity-based costing (ABC) results in a richer description of an organization's cost
behavior and CVP relationships. Costs that are fixed with respect to sales volume
may not be fixed with respect to other important cost drivers. An ABC system
recognizes these nonvolume cost drivers, whereas a traditional costing system does
not.

Answers will vary on this question, depending on the airline selected as well as the year of
the inquiry. All publicly-owned airlines disclose load factors; some disclose break-even
load factors. In a typical year, most airlines report a load factor of about 80% and a
breakeven load factor of around 65 percent, though it can vary quite dramatically from
company to company and year to year.

Annual fixed costs will increase by $90,000 ($450,000 ÷ 5 years) because of straightline depreciation associated with the new equipment, to $1,203,600 ($1,113,600 +
$90,000). The unit contribution margin is $48 ($2,208,000 ÷ 46,000 units). Thus:
Required sales = (fixed costs + target net profit) ÷ unit contribution margin
= ($1,203,600 + $956,400) ÷ $48

Advanced Electronics has a contribution margin of $58 [($3,360,000 - $924,000) ÷
42,000 sets] and desires to increase income to $312,000 ($156,000 x 2). In addition,
the current selling price is $80 ($3,360,000 ÷ 42,000 sets). Thus:
Required sales = (fixed costs + target net profit) ÷ unit contribution margin
= ($2,280,000 + $312,000) ÷ $58
= 44,690 sets (rounded), or $3,575,200 (44,690 sets x $80)
2.
If operations are shifted to Slovakia, the new unit contribution margin will be $64
($80 - $16). Thus:
Break-even point = fixed costs ÷ unit contribution margin
= $1,984,000 ÷ $64
= 31,000 units
3.
(a)
Advanced Electronics desires to have a 31,000-unit break-even point with a
$58 unit contribution margin. Fixed cost must therefore drop by $482,000
($2,280,000 - $1,798,000), as follows:
Let X = fixed costs
X ÷ $58 = 31,000 units
X = $1,798,000
(b)
As the following calculations show, Advanced Electronics will have to
generate a contribution margin of $73.55 to produce a 31,000-unit break-even
point. Based on an $80.00 selling price, this means that the company can
incur variable costs of only $6.45 per unit. Given the current variable cost of
$22.00 ($80.00 - $58.00), a decrease of $15.55 per unit ($22.00 - $6.45) is
needed.
Let X = unit contribution margin
$2,280,000 ÷ X = 31,000 units
X = $73.55 (rounded)

PROBLEM 7-39 (CONTINUED)
Consolidated would experience a larger percentage decrease in income if it adopts
Plan B. This situation arises because Plan B has a higher degree of operating
leverage. Stated differently, Plan B’s cost structure produces a greater percentage
decline in profitability from the drop-off in sales revenue.
Note: The percentage decreases in profitability can be computed by multiplying the
percentage decrease in sales revenue by the operating leverage factor. Sales
dropped from 6,000 units to 5,000 units, or 16.67%. Thus:
Plan A: 16.67% x 1.22 = 20.3% (difference due to rounding)
Plan B: 16.67% x 1.43 = 23.8% (rounded)
6.
Heavily automated manufacturers have sizable investments in plant and equipment,
along with a high percentage of fixed costs in their cost structures. As a result,
there is a high degree of operating leverage.
In a severe economic downturn, these firms typically suffer a significant
decrease in profitability. Such firms would be a more risky investment when
compared with firms that have a low degree of operating leverage. Of course, when
times are good, increases in sales would tend to have a very favorable effect on
earnings in a company with high operating leverage.

Celestial Products, Inc. would be indifferent between the two manufacturing
methods at the volume (X) where total costs are equal.
$16X + $2,940,000 = $19.60X + $1,820,000
$3.60X = $1,120,000
X = 311,111 units (rounded)
3.
Operating leverage is the extent to which a firm's operations employ fixed operating
costs. The greater the proportion of fixed costs used to produce a product, the
greater the degree of operating leverage. Thus, the computer-assisted
manufacturing method utilizes a greater degree of operating leverage.
The greater the degree of operating leverage, the greater the change in
operating income (loss) relative to a small fluctuation in sales volume. Thus, there
is a higher degree of variability in operating income if operating leverage is high.
4.
Management should employ the computer-assisted manufacturing method if annual
sales are expected to exceed 311,111 units and the labor-intensive manufacturing
method if annual sales are not expected to exceed 311,111 units.
5.
Celestial Products’ management should consider many other business factors
other than operating leverage before selecting a manufacturing method. Among
these are:
 Variability or uncertainty with respect to demand quantity and selling price.
 The ability to produce and market the new product quickly.
 The ability to discontinue production and marketing of the new product while
incurring the least amount of loss.

This reasoning leads to the following equation:

Rearranging terms yields the following:
(1.43 – 1.35)X = 11,000 – 8,000

X = 3,000/.08

Subject:
Activity-Based Costing
The $150,000 cost that has been characterized as fixed is fixed with respect to sales volume.
This cost will not increase with increases in sales volume. However, as the activity-based
costing analysis demonstrates, these costs are not fixed with respect to other important
cost drivers. This is the difference between a traditional costing system and an ABC system.
The latter recognizes that costs vary with respect to a variety of cost drivers, not just sales
volume.

4.
If management adopts the new manufacturing technology:
(a)
Its break-even point will be higher (17,500 units instead of 15,000 units).
(b)
The number of sales units required to show operating income of $140,000 will be
lower (27,515 units instead of 29,000 units).
(c)
These results are typical of situations where firms adopt advanced manufacturing
equipment and practices. The break-even point increases because of the
increased fixed costs due to the large investment in equipment. However, at
higher levels of sales after fixed costs have been covered, the larger unit
contribution margin ($14 instead of $10) earns a profit at a faster rate. This results
in the firm needing to sell fewer units to reach a given target profit level.

The controller should include the break-even analysis in the report. The Board of
Directors needs a complete picture of the financial implications of the proposed
equipment acquisition. The break-even point is a relevant piece of information. The
controller should accompany the break-even analysis with an explanation as to
why the break-even point will increase. It would also be appropriate for the
controller to point out in the report that the advanced manufacturing equipment
would require fewer sales units at higher volumes in order to achieve a given
target profit, as in requirement (3) of this problem.
To withhold the break-even analysis from the controller's report would be a
violation of the following ethical standards:
(a)
Competence: Provide decision support information and recommendations that are
accurate, clear, concise, and timely.
(b)
Integrity: Refrain from engaging in any conduct that would prejudice carrying out
duties ethically.
(c)
Credibility: Communicate information fairly and objectively. Disclose all relevant
information that could reasonably be expected to influence an intended user's
understanding of the reports, analyses, and recommendations.
