Understanding the Margin of Safety Concept:
Margin of Safety (MoS) measures how much sales can drop before the business reaches its break-even point.
It is calculated as: Margin of Safety Sales=Actual Sales−Break-even Sales\text{Margin of Safety Sales} = \text{Actual Sales} - \text{Break-even Sales}Margin of Safety Sales=Actual Sales−Break-even Sales
Applying the Formula:
Selling Price per Shirt: $8
Break-even Sales Volume: 25,000 shirts
Break-even Sales Value: 25,000×8=200,00025,000 \times 8 = 200,00025,000×8=200,000
Actual Sales Revenue: $300,000
Margin of Safety: 300,000−100,000=200,000300,000 - 100,000 = 200,000300,000−100,000=200,000
Why Option B ($200,000) Is Correct?
The margin of safety is the difference between actual and break-even sales.
The correct calculation confirms $200,000 as the margin of safety.
IIA Standard 2120 – Risk Management supports financial risk analysis, including break-even and margin of safety evaluations.
Why Other Options Are Incorrect?
Option A ($100,000): Incorrect subtraction.
Option C ($275,000): Incorrect calculation, not based on break-even sales.
Option D ($500,000): Irrelevant and exceeds actual sales.
The correct margin of safety is $200,000, calculated using standard break-even analysis.
IIA Standard 2120 emphasizes financial risk evaluation in decision-making.
