TL;DR: Intrinsic value is not a price you look up. It is an estimate you build, in this guide with a discounted cash flow model that projects future free cash flow and discounts it at a rate reflecting risk and the time value of money. In the simple worked example here, a business generating $100 in free cash flow, growing at 3 percent, discounted at 10 percent, has a simplified perpetuity value of about $1,471. Change either assumption and the answer moves a lot, which is the real lesson.
Key Takeaways
- Discounted cash flow methods rest on one idea: money in the future is worth less than money today, so future cash must be discounted. Asset-based and liquidation approaches value a business differently.
- The discounted cash flow method needs three inputs: a starting cash flow, a growth assumption, and a discount rate.
- Small changes in growth or the discount rate produce large changes in the result, so honest ranges beat single point answers.
- A margin of safety is the gap investors leave between estimated value and price to allow for being wrong.
- Cross-check one method against another, such as the approach in our reverse DCF explainer, instead of trusting a single model.
What does intrinsic value actually mean?
Intrinsic value means the value of an investment based on its own cash generating capacity, separate from the price the market currently puts on it. A stock's market price is set by trading. Its intrinsic value, in this framework, is set by the cash the underlying business can return to owners over its life, adjusted for when that cash arrives. If the two differ, an investor has a question to investigate, not an automatic conclusion, because the market may know something the model does not, or the model's assumptions may simply be wrong.
There is no single agreed formula, and that is normal. Analysts use discounted cash flow models, dividend discount models for dividend paying companies, and multiples as shorthand. All of them are ways of organizing assumptions. The discipline is to state your assumptions plainly, test how sensitive the answer is to them, and treat the output as a range. Anyone presenting intrinsic value as a single exact figure to the cent is presenting their assumptions with more confidence than the method supports.
How does a simple discounted cash flow calculation work?
The simplest version is the perpetuity growth model, useful for teaching the mechanics. It values a cash flow stream that grows at a constant rate forever. The formula is: value equals next year's free cash flow, divided by the discount rate minus the growth rate. It only holds when the discount rate exceeds the perpetual growth rate, and the cash flow definition must match the discount rate: free cash flow to the firm is discounted at the weighted average cost of capital, and free cash flow to equity at the cost of equity. Suppose a hypothetical business generates $100 of free cash flow this year, expected to grow at 3 percent a year. Next year's cash flow is $100 times 1.03, which equals $103. With a discount rate of 10 percent, the denominator is 0.10 minus 0.03, which equals 0.07. Divide $103 by 0.07 and the result is about $1,471.43.
Check the sensitivity, because it teaches more than the headline figure. Raise growth to 5 percent and the denominator becomes 0.05, so $105 divided by 0.05 equals $2,100. Lower the discount rate to 8 percent at the original growth and the denominator becomes 0.05, so $103 divided by 0.05 equals $2,060. A two point change in one assumption moved the value by 40 percent or more: raising growth by two points increases the estimate by about 42.7 percent, and lowering the discount rate by two points increases it by exactly 40 percent. Real models project several years explicitly and add a terminal value, but the same sensitivity applies. This is why careful investors run several scenarios. Our companion piece on the DCF calculator walks through what each input means in a fuller model.
How do you turn a business value into a per share value?
A discounted cash flow model usually values the whole business or its equity. To compare with a share price, divide by shares outstanding, after accounting for debt and cash if the model valued the enterprise rather than the equity directly. Using the teaching example, if the equity value were $1,471.43 million and the company had 100 million shares outstanding, the per share value would be $1,471.43 million divided by 100 million, which equals about $14.71 per share. The arithmetic is trivial. Getting the inputs defensible is the work.
Share count deserves care. Account consistently for potential dilution from options and convertible securities: if conversion is assumed in the share count, the related debt and cash flow treatment must be adjusted the same way, or the effect gets counted twice. Net debt matters the same way. In a simplified case, equity value equals enterprise value minus debt plus excess cash; a complete reconciliation also accounts for preferred stock, noncontrolling interests, and other relevant claims or nonoperating assets. Skipping that step is an error that can swing the per share answer materially for companies with large borrowings or large cash balances.
Why do investors demand a margin of safety?
Because every input is an estimate. Earnings disappoint, growth slows, rates rise. A margin of safety means requiring the price to sit meaningfully below your estimated value before the investment interests you, so that moderate errors in your assumptions do not automatically become losses. Graham, who formalized the idea, treated it as the central concept of investing. The size of the margin is a judgment call that grows with uncertainty: a stable, predictable business needs less cushion than a cyclical one with a short history.
Treat intrinsic value as the start of research, not the end of it. Read the filings, understand how the business makes money, check the balance sheet, and ask what would have to go wrong for your estimate to be far too high. Pair the valuation with a structured review such as our stock research checklist, so the number sits inside a process instead of replacing one.
FAQ
Can intrinsic value be negative? Yes, a raw model output can be negative, including when estimated enterprise value is below the debt and other claims against it. Ordinary common shares still have a value floor of zero because shareholders have limited liability. A negative or near zero output calls for reviewing the assumptions, the financing claims, and the model structure, rather than reading a single meaning into it.
Which discount rate should I use? There is no universal figure. A required rate of return can be built from the risk free rate plus a premium for equity risk, or from the company's weighted average cost of capital for enterprise models. State the rate you chose and test the answer at rates one or two points higher and lower.
Is a stock below intrinsic value automatically a good investment? No. It means price and one estimate differ. The estimate may be wrong, the business may face problems the model missed, or the price may stay below the estimate for a long time. The gap is a reason to research further, not a conclusion.
How is intrinsic value different from book value? Book value is an accounting figure from the balance sheet: assets minus liabilities at recorded values. Intrinsic value is a forward looking estimate based on future cash generation. A company can trade above or below both, for different reasons.
