Margin Of Safety Formula Definition

To define it, the Margin of Safety Formula is basically the difference between the break-even point and expected profitability. It’s equal to the present sales minus the breakeven point and divided by the current sales.

Any kind of revenue that would take your business above this break-even could be taken into account as the margin of safety. After considering the variable and fixed costs, if your business revenue goes above the break-even, it would be the margin of safety. Hence, the margin of safety definition is basically the quantifiable distance you are away from facing unprofitability.

How To Calculate Margin Of Safety?

How To Calculate Margin Of Safety?

Here, I have put forward an example of the margin of using the margin of safety formula. So, basically, it’s the difference between the two figures which makes it a simple subtraction.

Below is an example of how to calculate margin of safety:

Example 1:

Haiti enterprises give a dataset for April 2022:

  • Sales (3,500 units @ $20/unit): $70,000
  • Contribution margin per unit: $12
  • Total fixed expenses for the entire month: $15,000

There was no closing and opening, and closing of finished inventory in the stock

Question: Calculate the margin of safety and break-even point for Haiti Enterprises with the help of data. In addition, draw a CVP graph and depict the sales volume representing the margin of safety and break-even point on the graph.

Solution

1. Break Even Point

Break-Even Point In Units

The break-even point in units for Haiti Enterprises is:

Fixed Cost / Contribution margin each unit

= USD $15,000/ $12

=1250 Units

Break Even Point In Dollars:

Break even point in units × Selling price of each unit

= 1,250 units × USD $20

= USD $25,000

2. Margin Of Safety

Margin Of Safety In Percentage:

Actual Sales – Break Even Sales

= USD $70,000 – $25,000

= $45,000

It means that if the $45,000 is lost in the sales revenue, the profit will come down to zero, and every dollar that’s lost apart from it would be considered a loss.
