MANAGEMENT ACCOUNTING (VOLUME I) - Solutions Manual
CHAPTER 13
COST-VOLUME-PROFIT RELATIONSHIPS
I.
Questions
1. The total “contribution margin” is the excess of total revenue over total
variable costs. The unit contribution margin is the excess of the unit
price over the unit variable costs.
2. Total contribution margin:
Selling price - manufacturing variable costs expensed nonmanufacturing variable costs expensed = Total contribution margin.
Gross margin:
Selling price - variable manufacturing costs expensed - fixed
manufacturing costs expensed = Gross margin.
3. A company operating at “break-even” is probably not covering costs
which are not recorded in the accounting records. An example of such
a cost is the opportunity cost of owner-invested capital. In some small
businesses, owner-managers may not take a salary as large as the
opportunity cost of forgone alternative employment. Hence, the
opportunity cost of owner labor may be excluded.
4. In the short-run, without considering asset replacement, net operating
cash flows would be expected to exceed net income, because the latter
includes depreciation expense, while the former does not. Thus, the
cash basis break-even would be lower than the accrual break-even if
asset replacement is ignored. However, if asset replacement costs are
taken into account, (i.e., on a “cradle to grave” basis), the long-run net
cash flows equal long-run accrual net income, and the long-run breakeven points are the same.
5. Both unit price and unit variable costs are expressed on a per product
basis, as:
= (P1 - V1) X1 + (P2 - V2) X2 + + (Pn - Vn) Xn - F,
for all products 1 to n where:
P
=
=
operating profit,
average unit selling price,
13-1
Chapter 13 Cost-Volume-Profit Relationships
V =
X =
F =
average unit variable cost,
quantity of units,
total fixed costs for the period.
6. If the relative proportions of products (i.e., the product “mix”) is not
held constant, products may be substituted for each other. Thus, there
may be almost an infinite number of ways to achieve a target operating
profit. As shown from the multiple product profit equation, there are
several unknowns for one equation:
= (P1 - V1) X1 + (P2 - V2) X2 + + (Pn - Vn) Xn - F,
for all products 1 to n.
7. A constant product mix is assumed to simplify the analysis. Otherwise,
there may be no unique solution.
8. Operating leverage measures the impact on net operating income of a
given percentage change in sales. The degree of operating leverage at a
given level of sales is computed by dividing the contribution margin at
that level of sales by the net operating income.
9. Three approaches to break-even analysis are (a) the equation method,
(b) the contribution margin method, and (c) the graphical method. In
the equation method, the equation is: Sales = Variable expenses + Fixed
expenses + Profits, where profits are zero at the break-even point. The
equation is solved to determine the break-even point in units or peso
sales.
10. The margin of safety is the excess of budgeted (or actual) sales over the
break-even volume of sales. It states the amount by which sales can
drop before losses begin to be incurred.
11. The sales mix is the relative proportions in which a company’s
products are sold. The usual assumption in cost-volume-profit analysis
is that the sales mix will not change.
12. A higher break-even point and a lower net operating income could
result if the sales mix shifted from high contribution margin products to
low contribution margin products. Such a shift would cause the
average contribution margin ratio in the company to decline, resulting
in less total contribution margin for a given amount of sales. Thus, net
operating income would decline. With a lower contribution margin
ratio, the break-even point would be higher since it would require more
sales to cover the same amount of fixed costs.

Requirement 2
An increase in the variable expenses as a percentage of the selling price
would result in a higher break-even point. The reason is that if variable
expenses increase as a percentage of sales, then the contribution margin
will decrease as a percentage of sales. A lower CM ratio would mean that
more lanterns would have to be sold to generate enough contribution
margin to cover the fixed costs.

a. Sales of 37,500 doors represents an increase of 7,500 doors, or 25%,
over present sales of 30,000 doors. Since the degree of operating
leverage is 6, net operating income should increase by 6 times as much,
or by 150% (6 × 25%).

Requirement 3
The additional contribution margin from the additional sales can be
computed as follows:
P50,000 × 63% CM ratio = P31,500
Assuming no change in fixed expenses, all of this additional contribution
margin should drop to the bottom line as increased net operating income.
This answer assumes no change in selling prices, variable costs per unit,
fixed expenses, or sales mix.

net operating income will increase by the amount of the increased
contribution margin, P24,000.

Note from the income statement above that the increase in sales from
20,000 to 21,600 units has resulted in increases in both total sales and
total variable expenses. It is a common error to overlook the increase
in variable expense when preparing a projected income statement.

before:
=

= P1,440,000 – P1,050,000 = P390,000
As shown in requirement (5) above, the company’s present margin of
safety is only P240,000. Thus, several benefits will result from the
proposed changes.

c. Whether or not one would recommend that the company automate its
operations depends on how much risk he or she is willing to take, and
depends heavily on prospects for future sales. The proposed changes
would increase the company’s fixed costs and its break-even point.
However, the changes would also increase the company’s CM ratio
(from 30% to 65%). The higher CM ratio means that once the breakeven point is reached, profits will increase more rapidly than at present.
If 20,000 units are sold next month, for example, the higher CM ratio
will generate P22,000 more in profits than if no changes are made.

Cost-Volume-Profit Relationships Chapter 13
The greatest risk of automating is that future sales may drop back down
to present levels (only 13,500 units per month), and as a result, losses
will be even larger than at present due to the company’s greater fixed
costs. (Note the problem states that sales are erratic from month to
month.) In sum, the proposed changes will help the company if sales
continue to trend upward in future months; the changes will hurt the
company if sales drop back down to or near present levels.
Note to the Instructor: Although it is not asked for in the problem, if
time permits you may want to compute the point of indifference
between the two alternatives in terms of units sold; i.e., the point
where profits will be the same under either alternative. At this point,
total revenue will be the same; hence, we include only costs in our
equation:
Let Q = Point of indifference in units sold
P14Q + P90,000 = P7Q + P208,000
P7Q = P118,000
Q = P118,000 ÷ P7 per unit
Q = 16,857 units (rounded)
If more than 16,857 units are sold, the proposed plan will yield the greatest
profit; if less than 16,857 units are sold, the present plan will yield the
greatest profit (or the least loss).

Requirement 3
Memo to the president:
Although the company met its sales budget of P500,000 for the month, the
mix of products sold changed substantially from that budgeted. This is the
reason the budgeted net operating income was not met, and the reason the
break-even sales were greater than budgeted. The company’s sales mix
was planned at 48% Sinks, 20% Mirrors, and 32% Vanities. The actual
sales mix was 32% Sinks, 40% Mirrors, and 28% Vanities.
As shown by these data, sales shifted away from Sinks, which provides our
greatest contribution per peso of sales, and shifted strongly toward Mirrors,
which provides our least contribution per peso of sales. Consequently,
although the company met its budgeted level of sales, these sales provided
considerably less contribution margin than we had planned, with a resulting
decrease in net operating income. Notice from the attached statements that
the company’s overall CM ratio was only 43%, as compared to a planned
CM ratio of 52%. This also explains why the break-even point was higher
than planned. With less average contribution margin per peso of sales, a
greater level of sales had to be achieved to provide sufficient contribution
margin to cover fixed costs.

Since there are no fixed costs, the number of unit sales needed to yield the
desired P7,200 in profits can be obtained by dividing the target profit by
the unit contribution margin:
P7,200
Target profit
=
P9 per patch = 800 patches
Unit contribution margin
800 patches x P30 per patch =
P24,000 in total sales
Requirement 2
Since an order has been placed, there is now a “fixed” cost associated with
the purchase price of the patches (i.e., the patches can’t be returned). For
example, an order of 200 patches requires a “fixed” cost (investment) of
P3,000 (200 patches × P15 per patch = P3,000). The variable costs drop to
only P6 per patch, and the new contribution margin per patch becomes:
Selling price................................................................................................................
P30
Less variable expenses (commissions only).............................................................

Contribution margin...................................................................................................
P24
Since the “fixed” cost of P3,000 must be recovered before Ms. Morales
shows any profit, the break-even computation would be:
