Total cost of a product is Rs 60000 and profit is 25% on selling price then profit

The margin of safety is the level of real sales above the breakeven point

What is Margin of Safety?

The margin of safety is the difference between the amount of expected profitability and the break-even point. The margin of safety formula is equal to current sales minus the breakeven point, divided by current sales.

Understanding Margin of Safety

There are two applications to define the margin of safety:

In budgeting and break-even analysis, the margin of safety is the gap between the estimated sales output and the level by which a company’s sales could decrease before the company becomes unprofitable. It signals to the management the risk of loss that may happen as the business is subjected to changes in sales, especially when a significant amount of sales are at risk of decline or unprofitability.

A low percentage of margin of safety might cause a business to cut expenses, while a high spread of margin assures a company that it is protected from sales variability.

In the principle of investing, the margin of safety is the difference between the intrinsic value of a stock against its prevailing market price. Intrinsic value is the actual worth of a company’s asset or the present value of an asset when adding up the total discounted future income generated.

When applied to investing, the margin of safety is calculated by assumptions, meaning an investor would only buy securities when the market price is materially below its estimated intrinsic value. Determining the intrinsic value or true worth of a security is highly subjective because each investor uses a different way of calculating intrinsic value, which may or may not be accurate.

The fair market price of the security must be known in order to use the discounted cash flow analysis method then to give an objective, fair value of a business.

What is the Margin of Safety Formula?

In accounting, the margin of safety is calculated by subtracting the break-even point amount from the actual or budgeted sales and then dividing by sales; the result is expressed as a percentage.

The margin of safety formula can also be expressed in dollar amounts or number of units:

Practical Example

Ford Co. purchased a new piece of machinery to expand the production output of its top-of-the-line car model. The machine’s costs will increase the operating expenses to $1,000,000 per year, and the sales output will likewise augment.

After the machine was purchased, the company achieved a sales revenue of $4.2M, with a breakeven point of $3.95M, giving a margin of safety of 5.8%.

What is the Ideal Margin of Safety for Investing Activities?

The extent of margin of safety depends on investor preference and the type of investment he chooses. Some of the various scenarios an investor may find interest in with a substantial spread of margin are:

• Deep value investing – Buying stocks in seriously undervalued businesses. The main goal is to search for significant mismatches between current stock prices and the intrinsic value of these stocks. Such type of investing requires a large amount of margin to invest with and takes lots of guts, as it is risky.
• Growth at reasonable price investing – Choosing companies with positive growth trading rates that are somehow below the intrinsic value.

How Important is the Margin of Safety?

A high safety margin is preferred, as it indicates sound business performance with a wide buffer to absorb sales volatility. On the other hand, a low safety margin indicates a not-so-good position. It must be improved by increasing the selling price, increasing sales volume, improving contribution margin by reducing variable cost, or adopting a more profitable product mix.

For investors, the margin of safety serves as a cushion against errors in calculation. Since fair value is difficult to predict accurately, safety margins protect investors from poor decisions and downturns in the market.
