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.
