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 break-even 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 breakeven point would be higher since it would require more sales to cover the same amount of fixed costs. II.

or at P900 per lantern, P4,500,000 in sales 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. Requirement 3

Sales Less variable expenses Contribution margin Less fixed expenses Net operating income

* 8,000 lanterns × 1.25 = 10,000 lanterns ** P900 per lantern × 0.9 = P810 per lantern As shown above, a 25% increase in volume is not enough to offset a 10% reduction in the selling price; thus, net operating income decreases.

Requirement 2 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%). b.

Requirement 2 The break-even point for the company as a whole would be: Break-even point Fixed expenses = in total peso sales Overall CM ratio P598,500 = 0.63 =

P950,000 in sales

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.

or, at P40 per unit, P500,000. Requirement 2 The contribution margin at the break-even point is P150,000 since at that point it must equal the fixed expenses. Requirement 3 Unit sales to attain target profit

Alternative solution: P80,000 incremental sales × 30% CM ratio = P24,000

Since in this case the company’s fixed expenses will not change, monthly net operating income will increase by the amount of the increased contribution margin, P24,000. III. Problems Problem 1 (CVP Relationships) Requirement 1 CM ratio Variable expense ratio

c. If sales increase by 8%, then 21,600 units (20,000 x 1.08 = 21,600) will be sold next year. The new income statement will be as follows: Sales (21,600 units)............... Less variable expenses........... Contribution margin.............. Less fixed expenses................ Net operating income.............

Thus, the P84,000 expected net operating income for next year represents a 40% increase over the P60,000 net operating income earned during the current year: P84,000 – P60,000 = P60,000

P24,000 P60,000

= 40% increase

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. Requirement 7 a. A 20% increase in sales would result in 24,000 units being sold next year: 20,000 units x 1.20 = 24,000 units. Sales (24,000 units)............... Less variable expenses...........

Although the changes will also result in a higher breakeven point (17,500 units as compared to the present 16,000 units), the company’s margin of safety will actually be wider than before: =

Margin of safety in pesos = Total sales – Break-even sales = 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. Problem 2 (Basics of CVP Analysis; Cost Structure) Requirement 1 The CM ratio is 30%. Total P270,000 189,000 P 81,000

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 break-even 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. 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 13-16


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.

No, the changes should not be made. Requirement 6 Expected total contribution margin: 28,000 units × 200% × P70 per unit*.................................................................. P3,920,000 Present total contribution margin: 28,000 units × P90 per unit................................................................................. 2,520,000 Incremental contribution margin, and the amount by which advertising can be increased with net operating income remaining unchanged........................................................................................... P1,400,000 * P150 – (P60 + P20) = P70 Problem 5 (Break-Even and Target Profit Analysis) 13-19


Requirement 1 The contribution margin per patch would be: Selling price............................................................................................................. P30 Less variable expenses: Purchase cost of the patches................................................................................ P15 Commissions to the student salespersons............................................................. 6 21 P 9 Contribution margin................................................................................................. 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)............................................................. 6 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:

Break-even point = in unit sales


P3,000 = P24 per patch 13-20

= 125 patches


125 patches x P30 per patch = P3,750 in total sales If a quantity other than 200 patches were ordered, the answer would change accordingly. Problem 6 Requirement 1: Break-even chart TR
