Instead, you apply the margin of safety—let’s say you aim for a margin of 25%. With that margin of safety, the price you would try to acquire the stock at would be $60. Current sales represent the latest possible information regarding a businesses’ sales, represented by a dollar value – if you’re looking to the future, you can use estimated sales.

If the hurdle is set at 20%, the investor will only purchase a security if the current share price is 20% below the intrinsic value based on their valuation. The use of a factor of safety does not imply that an item, structure, or design is “safe”. Many quality assurance, engineering design, manufacturing, installation, and end-use factors may influence whether or not something is safe in any particular situation. That means revenue from the sale of 375,000 units is enough to cover the entire production cost.

That way, the company can incur unforeseen expenses or losses without a significant impact on profitability. The margin of safety principle was popularized by famed British-born American investor Benjamin Graham (known as the father of value investing) and his followers, most notably Warren Buffett. Investors utilize both qualitative and quantitative factors, including firm management, governance, industry performance, assets and earnings, to determine a security’s intrinsic value. The market price is then used as the point of comparison to calculate the margin of safety.

If Netflix is destined to evolve into a no-growth company, a P/E of less than 18 may be realistic when you calculate its intrinsic value. Using the margin of safety to make investment choices — for example, only investing when it is greater than 20% — is often referred to as value investing. Right—now that we’ve dealt with the basics, let’s move on to something that’s a bit more practical. The margin of safety, as a concept, has both advantages and disadvantages—although to be perfectly frank, a lot of the time it’s simply a question of whether or not the approach works for your specific needs. Put simply, the margin of safety is the difference between a stock’s intrinsic value and its market value. In order to minimize risk, your aim is to purchase stocks whose intrinsic value is greater than their current market value—for whatever reason.

At a lower margin of Safety, the organisation will need to make changes by cutting down some of its expenses. You can calculate the margin of safety in units, revenue, and percentage. In Budgeting, the distance between current or anticipated future sales and the breakeven point is known as the margin of safety. This is the bare minimum amount of sales required to prevent product sales losses. Companies can decide whether or not to make adjustments based on the information by estimating the margin of safety. In accordance with the investing theory known as the “margin of safety,” a stock is only bought by a buyer when its market price is much less than its intrinsic worth.

Similar to the MOS in value investing, the larger the margin of safety here, the greater the “buffer” between the break-even point and the projected revenue. The formula for calculating the MOS requires knowing the forecasted revenue and the break-even revenue for the company, which is the point at which revenue adequately covers all expenses. Generally, the majority of value investors will NOT invest in a security unless the MOS is calculated to be around ~20-30%. Therefore, the margin of safety is a “cushion” that allows some losses to be incurred without suffering any major implications on returns.

5 Calculate and Interpret a Company’s Margin of Safety and Operating Leverage

Management uses this calculation to judge the risk of a department, operation, or product. The smaller the percentage or number of units, the riskier the operation is because there’s less room between profitability and loss. For instance, a department with a small buffer could have a loss for the period if it experienced a slight decrease in sales.

  • In other words, Bob could afford to stop producing and selling 250 units a year without incurring a loss.
  • Value investors lean on it the most, but growth investors, income-focused investors, and even derivative and option investors should use the concept.
  • After a year of using the software program, the company’s sales reach $880,000, with a breakeven point of $800,000.
  • Is as a measure of satisfying design requirements (requirement verification).

The term ‘margin of safety’ was initially coined by the investors, Benjamin Graham and David Dodd, to refer to the gap between an investment’s intrinsic value and its market value. An asset or security’s intrinsic value is the value or price an investor believes to be the “real or true worth” of that asset, independent of what others (the market) think. But this value varies between investors because they use different metrics to estimate it. Investors try to buy assets at a price lower than their intrinsic value so that they can cushion against future losses from possible errors in their estimations. Sales can decrease by $45,000 or 3,000 units from the budgeted sales without resulting in losses. If it decreases by more than $45,000 (or by more than 3,000 units) the business will have operating loss.


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. 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. The margin of safety ratio, which highlights the gap between actual and break-even sales, can assess a company’s financial health. When the margin of safety is significant, the company is likely in good financial shape, and its cash flows are more stable. Current sales units minus breakeven point equals [margin of safety units]. It’s important to remember that the margin of safety you calculate for an investment is only as good as the intrinsic value calculation.

In other words, the total amount of sales can be lost before the business loses money. Occasionally, it’s also helpful to represent this estimate as a percentage. Calculating the gap between budgeted and breakeven sales is a critical task for organisations today.

Business Example):

In these cases, annualise the data to account for all seasonal variations in the outcome. With earnings per share (EPS) of $11.02, that means Netflix’s stock price is about $200 per share, and its intrinsic value is about $265. The margin of safety is the percent difference between the intrinsic value of a stock and the current price. The wider your margin of safety is, the better chance that overly optimistic valuation inputs won’t doom your investment. Founded in 1993, The Motley Fool is a financial services company dedicated to making the world smarter, happier, and richer.

By selectively investing in securities only if there is sufficient “room for error”, the downside risk of the investor is protected. For loading that is cyclical, repetitive, or fluctuating, it is important to consider the possibility of metal fatigue when choosing factor of safety. A cyclic load well below a material’s yield strength can cause failure if it is repeated through enough cycles. The applied loads have many factors, including factors of safety applied. By this definition, a structure with an FOS of exactly 1 will support only the design load and no more. Margin of safety may also be expressed in terms of dollar amount or number of units.


But the fact remains—this is a lens that can only be used to gauge the quality of a certain type of stock, so it is a bit inflexible and lacking overall. We’ll use a nice, obvious example—a company that fits the bill to a T and that’s often mentioned in the news—Tesla. The most staunch and famous value investors, Warren Buffet and Charlie Munger were actually disciples of Ben Graham, who is often referred to as the father of value investing. It was Ben Graham who coined the very term margin of safety in his 1934 book, Security Analysis, co-written with David Dodd.

The breakeven point (also known as breakeven sales) is the point where total costs (expenses) and total sales (revenue) are equal or “even”. A margin of safety is a tool used by business owners and sales managers to determine how much leeway they have before a decline in sales results in a loss of profits. A business has a solid protective buffer if its sales have a significant margin of safety. When your margin of safety is high, you may devote more funds to expansion without worrying about jeopardising your bottom line.
