In order to evaluate the Sticker Price you want to find the Future Growth Rate, the P/E Ratio, and your Minimum Acceptable Rate of Return. The Future Growth Rate is always an estimate, the other numbers you can find on financial statements and plug them into the calculator above to see the value, or Sticker Price, of the company’s stock. Next, you simply cut that price in half (or take 50%) and that is your Margin of Safety price. In this particular example, the MOS is 25% — meaning that the share price can drop by 25% before reaching the estimated intrinsic value of $8.

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. Conceptually, the margin of safety could be thought of as the difference between the estimated intrinsic value and the current share price. The Margin of Safety is the discount rate you can buy a wonderful business at as a Rule One investor, which is generally 50% off the Sticker Price, or fair value of the company’s share price. Suppose a company’s shares are trading at $10, but an investor has estimated the intrinsic value at $8.

## Sticker Price:

See Chapter 9 of Rule #1 for a refresher on choosing a historical growth rate. Note that the denominator can also be swapped with the average selling price per unit if the desired result is the margin of safety in terms of the number of units sold. 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%.

- Next, you simply cut that price in half (or take 50%) and that is your Margin of Safety price.
- And if the margin of safety is -1, then the part will fail even before reaching its design load.
- In this particular example, the MOS is 25% — meaning that the share price can drop by 25% before reaching the estimated intrinsic value of $8.

Margin of Safety Calculator calculate the margin of safety which is a financial ratio to measure the difference between actual sales and break-even point. Margin of safety formula is given below to show you how to calculate margin of safety quickly and easily. The margin of safety (MOS) is one of the fundamental principles in value investing, where securities are purchased only if their share price is currently trading below their approximated intrinsic value.

## Future Value:

If not, there is no “room for error” in the valuation of the shares, meaning that the share price would be lower than the intrinsic value following a minor decline in value. To estimate the margin of safety in percentage form, the following formula can be used. For example, if a company expects revenue of $50 million but only needs $46 million to break even, we’d subtract the two to arrive at a margin of safety of $4 million. By only investing if there is sufficient “room for error”, an investor’s downside is more protected. Therefore, the margin of safety is a “cushion” allowing for some degree of losses to be incurred without suffering any major implications on returns. The Margin of Safety represents the downside risk protection afforded to an investor when the security is purchased significantly below its intrinsic value.

The margin of safety is a concept that shows how far above (or below) a company’s stock is trading compared with the company’s intrinsic value. This calculator will compute the margin of safety for a company in terms of both a percentage and amount of sales, given the company’s break-even point and its expected sales. Since RULERS do a lot of research into businesses before buying into them, it should always be something you’re confident in purchasing. However, anything can happen with the stock market, and it makes sense to allot yourself an extra measure of protection.

## How to Calculate Margin of Safety

Because the Margin of Safety is just 50% of the Sticker Price, it allows you the ability to purchase into the business with lower risk. Setting this limitation on the price of a business before you buy it helps protect you by providing an extra 50% cushion off the value of the company. If we divide the $4 million safety margin by the projected revenue, the margin of safety is calculated as 0.08, or 8%. 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.

- If we divide the $4 million safety margin by the projected revenue, the margin of safety is calculated as 0.08, or 8%.
- This calculator determines ROIC; the most important number to tell you if a business is being run well.
- See Chapter 9 of Rule #1 for a refresher on choosing a historical growth rate.
- By only investing if there is sufficient “room for error”, an investor’s downside is more protected.
- 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.

This calculator determines ROIC; the most important number to tell you if a business is being run well. For example, if you wanted to buy into a business that was worth $80 per share (Sticker Price), you would look for a Margin of Safety of $40. If the company cannot be bought at $40 then you should add it to your watchlist, update your calculations periodically as new information becomes available, and exercise patience. From a different viewpoint, the MOS is the total amount of revenue that could be lost by a company before it begins to lose money.

If the margin of safety is 0, then the product will fail when it reaches its design load. If the margin of safety is 1, then the part can withstand load more than its design load. And if the margin of safety is -1, then the part will fail even before reaching its design load. To find the Margin of Safety, you first need to find the Sticker Price of a business and its stock.
