Read this text on break-even point analysis. It goes through the process of calculating the break-even point for cost analysis under different scenarios. Take notes on each of the following: define the break-even point, differentiate between fixed and variable costs, and write the formulas on how to calculate the break-even point, calculate the contribution margin, calculate the contribution margin ratio, and calculate the margin of safety.
Margin of Safety
If a company's current sales are more than its break-even point, it has a margin of safety equal to current sales minus break-even sales. The margin of safety is the amount by which sales can decrease before the company incurs a loss. For example, assume Video Productions currently has sales of USD 120,000 and its break-even sales are USD 100,000. The margin of safety is USD 20,000, computed as follows:
Sometimes people express the margin of safety as a percentage, called the margin of safety rate. The margin of safety rate is equal to . Using the data just presented, we compute the margin of safety rate as follows:
This means that sales volume could drop by 16.67 percent before the company would incur a loss.
