How does the margin of safety function?

The margin of safety is the difference between the anticipated profitability and the break-even point. The margin of safety calculation is current sales divided by current sales less the breakeven point.

Understanding the safety margin

There are two ways to define the margin of safety:

Establishing a budget

In budgeting and break-even analysis, the margin of safety is the difference between the planned sales production and the amount by which a firm’s sales could decrease before the company becomes unprofitable.

When a significant chunk of sales is in danger of dropping or becoming unprofitable, it warns management of the possible loss that could happen as a result of changes in sales.

While a large margin spread protects a company against unpredictable sales, a small percentage margin of safety may drive a company to cut costs.


The difference between a stock’s intrinsic value and its present market price is referred to as the margin of safety in investing. Intrinsic value, often known as present value, is the amount an asset is genuinely worth after deducting all discounted future income.

The margin of safety is the level at which an investor would only buy assets when the market price is far below the predicted intrinsic value. Determining the inherent value or genuine worth of an investment is extremely subjective because every investor utilises a different technique of calculation that may or may not be accurate.

The fair market price of the security must be known in order to perform the discounted cash flow analysis approach and afterwards calculate the fair value of a corporation objectively.

What’s the formula for the margin of safety?

After subtracting the break-even point amount from the actual or anticipated sales and dividing the result by sales, the result is expressed as a percentage in accounting.

The margin of safety is equal to Breakeven Point divided by Current Sales Level multiplied by 100.

The margin of safety formula can also be expressed in terms of money or units:

Current Sales – Breakeven Sales equals the dollar-based margin of safety.

Margin of Safety in Units = Breakeven Point – Current Sales Units

How to Calculate MOS Using a Calculator?

To calculate the margin of safety, the user only needs to enter the following data into the calculator.

Actual Sales

You calculate the margin of safety based on the total real sales of the Company (net of returns) for the accounting period. Additionally, we may calculate the value of the actual sales by dividing the actual sales unit by the selling price per unit.

These details can be found in the company’s profit and loss statement.

Sales at BEP

It is the sales volume at which a company is neither making a profit nor losing money. In other words, because the revenue the company generates only covers the variable costs of the commodity or service, it is in a position where it cannot turn a profit and cannot lose money.

To calculate breakeven sales, we deduct fixed costs from contribution per unit.

What Safety Margin is Best for Investment Activities?

The magnitude of an investor’s margin of safety will depend on the sort of investment he chooses and his preferences. A potential investor might be interested in any of the several opportunities with a sizable spread of margin, including the following:

Deep value investing is the practise of buying shares in firms that are significantly undervalued. The main goal is to find significant differences between the current stock prices and their true value. Such risky investing necessitates a wide margin of safety and a lot of bravery.

Growth at reasonable pricing is the practice of purchasing shares of firms with strong growth that trade at levels that are somewhat below intrinsic value.

What Importance Does the Safety Margin Have?

Large safety margins are preferred because they signal strong business success and act as a significant cushion against sales fluctuation. On the other hand, a tiny safety margin denotes a worse-than-ideal circumstance.

It needs to be improved by raising the selling price, raising the sales volume, raising the contribution margin by cutting back on variable costs, or by switching to a more profitable product mix.

Investors are protected from calculation errors by the margin of safety. Due to the difficulty in accurately estimating fair value, safety margins protect investors against poor judgments and market downturns.
