Margin of Safety



To calculate the margin of safety, determine the break-even point and the budgeted sales. Subtract the break-even point from the actual or budgeted sales and then divide by the sales. The number that results is expressed as a percentage.


The margin of safety is the difference between actual sales and break-even sales, while the degree of operating leverage (DOL) shows how a company's operating income changes after a percentage change in its sales.


Another definition: In break-even analysis, from the discipline of accounting, margin of safety is how much output or sales level can fall before a business reaches its break-even point. Break-even point is a no-profit, no-loss scenario.


Benjamin Graham and David Dodd, founders of value investing, coined the term margin of safety in their seminal 1934 book, Security Analysis. The term is also described in Graham's The Intelligent Investor. Graham said that "the margin of safety is always dependent on the price paid".[1]


Using margin of safety, one should buy a stock when it is worth more than its price in the market. This is the central thesis of value investing philosophy which espouses preservation of capital as its first rule of investing. Benjamin Graham suggested to look at unpopular or neglected companies with low P/E and P/B ratios. One should also analyze financial statements and footnotes to understand whether companies have hidden assets (e.g., investments in other companies) that are potentially unnoticed by the market.


The margin of safety protects the investor from both poor decisions and downturns in the market. Because fair value is difficult to accurately compute, the margin of safety gives the investor room for investing. Warren Buffett famously analogized margin of safety to driving across a bridge:


A common interpretation of margin of safety is how far below intrinsic value one is paying for a stock. For high quality issues, value investors typically want to pay 90 cents for a dollar (90% of intrinsic value) while more speculative stocks should be purchased for up to a 50 percent discount to intrinsic value (pay 50 cents for a dollar).[3]


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.


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 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:


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.


The problem is that the whole flight system includes much more than just the reliability of the plane itself. Just because we built-in safety margins in one area does not mean the system will not fail. This illustrates not so much a failure of the model itself, but a common mistake in the way the model is applied.


The authors have defined the margin of safety in positioning a double-lumen tube as the length of tracheobronchial tree over which it may be moved or positioned without obstructing a conducting airway. The purpose of this study was to measure the margin of safety in positioning three modern double-lumen tubes (Mallinkrodt [Broncho-Cath], Rusch [Endobronchial tubes], and Sheridan [Broncho-Trach]). The margin of safety in positioning a: 1) left-sided double-lumen tube (all manufacturers) is the length of the left mainstem bronchus minus the length from the proximal margin of the left cuff to left lumen tip; 2) Mallinkrodt right-sided double-lumen tube is the length of the right mainstem bronchus minus the length of the right cuff; and 3) Rusch right-sided double-lumen tube is the length of the right upper lobe ventilation slot minus the diameter of the right upper lobe. The length of the right and left mainstem bronchi were measured by in vivo fiberoptic bronchoscopy (n = 69), in fresh cadavers (n = 42), and in lung casts (n = 55), and the diameter of the right upper lobe bronchus was measured in lung casts (n = 55). The average +/- SD male left and right mainstem bronchial lengths were 49 +/- 8 and 19 +/- 6 mm, respectively, the average +/- SD female left and right mainstem bronchial lengths were 44 +/- 7 and 15 +/- 5 mm, respectively, the average right upper lobe bronchial diameter was 11 mm, the proximal left cuff to left lumen tip distance was 30 mm, the length of the Mallinkrodt right cuff was 10 mm, and the length of the Rusch right upper lobe ventilation slot was 15 mm. The average margin of safety in positioning left-sided double-lumen tubes ranged 16-19 mm for the different manufacturers. The average margin of safety in positioning Mallinkrodt right-sided double-lumen tubes was 8 mm, and the margin of safety in positioning Rusch right-sided double-lumen tubes ranged 1-4 mm, depending on French size. The authors concluded that left-sided double-lumen tubes are much preferable to right-sided double-lumen tubes because they have a much greater positioning margin of safety, and that proper confirmation of proper position of either a left- or right-sided double-lumen tube should be aided by fiberoptic bronchoscopy, because the absolute distances that constitute the margin of safety are extremely small. 041b061a72
