Question
Casas Modernas of Juarez, Mexico, is contemplating a major change in its cost structure. Currently, all of its drafting work is performed by skilled draftsmen. Rafael Jiminez, Casas’ owner, is considering replacing the draftsmen with a computerized drafting system. However, before making the change, Rafael would like to know the consequences of the change, since the volume of business varies significantly from year to year. Shown below are CVP income statements for each alternative.
Calculate the increase in Net income for each alternative if sales increased by $127,000.
Which alternative would produce the higher net income ?
Calculate the margin of safety ratio
Using the margin of safety ratio, determine which alternative could sustain the greater decline in sales before operating at a loss.

Explanation / Answer
Casas Modernas
Determination of increase in net income if sales for each alternative increased by $127,000:
Degree of operating leverage is an effective tool to determine the change in net income with change in sales level.
Degree of operating leverage = contribution margin/net income
Manual System
Computerized System
degree of operating leverage
Contribution margin
$282,000
$846,000
Net Income
$181,935
$181,935
degree of operating leverage
282,000/181,935
846,000/181,935
1.55
4.65
change in net income -
increase in sales
$127,000
$127,000
% increase in sales 127,000/1,410,000
127,000/1,410,000
9%
9%
Change in net income = percent increase in sales x degree of operating leverage
9% x 1.55
9% x 4.65
13.96%
41.85%
Hence, when sales increase by $127,000, net income increases by 13.96% under manual system and 41.85% in computerized system.
Net income –
Manual System - $1,410,000 x 13.96% = $196,836
Computerized System = $1,410,000 x 41.85% = $590,085
Alternative 2, Computerized System would produce the higher net income.
Margin of safety ratio:
Margin of safety ratio = margin of safety/sales
Margin of safety = actual sales – Break-even sales
Actual sales = $1,410,000
Break-even sales = fixed cost/contribution margin ratio
Manual system –
Contribution margin ratio = contribution margin/sales
= (282,000/1,410,000) x 100 = 20%
Fixed cost = $100,065
Break-even sales = 100,065/20% = $500,325
Margin of safety = $1,410,000 - $500,325 = $909,675
Margin of safety = $909,675
Margin of safety ratio = (909,675/1,410,000) x 100 = 64.52%
Computerized System –
Contribution margin ratio = contribution margin/sales
= (846,000/1,410,000) x 100 = 60%
Fixed cost = $664,065
Break-even sales = 664,065/60% = $1,106,775
Margin of safety = 1,410,000 – 1,106,775 = $303,225
Margin of safety = $303,225
Margin of safety ratio = 303,225/1,410,000 = 21.51%
Hence, the margin of safety and margin of safety ratio for the two alternatives is as follows,
Manual System
Computerized System
Margin of safety
$909,675
$303,225
margin of safety ratio
64.52%
21.51%
The margin of safety is highest for Manual System (64.52%) compared to the Computerized System (21.51%), hence Manual System - alternative could sustain the greater decline in sales before operating at a loss.
