Intrinsic value is an estimate of what a business is actually worth, based on the cash it can produce for its owners over the rest of its life. It is not the share price. The share price is only what someone paid for the last share that changed hands. When price and intrinsic value sit far apart, an investor wants to understand why.
The important word is estimate. Intrinsic value is never one exact figure. It is a range that moves with the assumptions you make about the future, and two careful analysts can reach different answers for the same company without either of them being careless.
Why price and value drift apart
Benjamin Graham, Warren Buffett's teacher, described the market as a voting machine in the short run and a weighing machine in the long run. Day to day, prices react to headlines, interest rates, fear and enthusiasm. The value of the underlying business changes much more slowly, because sales, profits and cash flow change slowly.
That gap is the whole reason intrinsic value matters. If price always equalled value, there would be nothing to analyse. Because it doesn't, an investor who can estimate value with reasonable care has a reference point that the daily noise can't move.
How intrinsic value is calculated
In words: a business is worth all the cash it will hand to its owners in the future, adjusted for the fact that money received later is worth less than money received today. That adjustment is called discounting. The discount rate is the yearly return you require for taking the risk of owning the business.
The most common method is the discounted cash flow (DCF) model. It works in four steps:
Start with the company's free cash flow, the cash left after running the business and paying for new equipment.
Project how fast that cash flow will grow over the next five to ten years.
Estimate a terminal value, a single figure for everything the business earns after that period.
Discount all of it back to today and divide by the number of shares.
For a business expected to grow at a steady rate forever, the whole model collapses into one short formula:
Value per share = next year's cash per share ÷ (discount rate − growth rate)
A worked example
These numbers are invented for illustration. Imagine a company that produces $10 of free cash flow per share this year. You expect that cash to grow 4% a year, and you want a 10% yearly return.
Next year's cash: $10 × 1.04 = $10.40
Discount rate minus growth: 10% − 4% = 6%
Value per share: $10.40 ÷ 0.06 ≈ $173
Now change one assumption. If growth is 3% instead of 4%, the value falls to about $147. If growth is 5%, it rises to $210. One percentage point of growth moves the answer by 15 percent or more in either direction. That sensitivity is the most important thing to understand about intrinsic value.
DCF is not the only method. Dividend-paying companies are often valued with a dividend discount model, and many investors cross-check against what similar companies trade for. Each method answers the same question from a different angle.
What a good number looks like
Intrinsic value on its own is neither good nor bad. What matters is how it compares with the current price. Investors usually express the gap as upside:
Upside = intrinsic value ÷ share price − 1
An estimated value of $150 against a price of $120 gives 25% upside. A negative number means the stock trades above your estimate.
How much trust to put in that gap depends heavily on the type of business:
Stable, predictable companies (consumer staples, established software, utilities) produce the most reliable estimates, because their cash flows are easier to project.
Cyclical companies (steel, airlines, chemicals) can look extremely cheap at the top of a cycle, when profits are temporarily high. A DCF built on peak cash flow overstates value.
Young or unprofitable companies get almost all of their value from the terminal value, so the estimate is mostly a guess about the distant future.
Banks and insurers don't have free cash flow in the usual sense, because lending and investing customer money is their core business. A standard DCF gives misleading results for them, and analysts usually work from book value and return on equity instead.
What intrinsic value doesn't tell you
This is the part most explanations skip, and it matters more than the formula.
It is only as good as its inputs. As the example shows, small changes in growth or discount rate produce large changes in the result. A model can be made to say almost anything.
It suggests more precision than exists. A figure like $187.43 looks exact. It isn't. Treat any single number as the middle of a wide range.
It says nothing about timing. A stock can trade below a sound estimate of its value for years. Nothing forces the price to close the gap.
A stock below its estimated value is not automatically a bargain. Often the market is pricing in a problem the model doesn't capture: a weakening competitive position, a pending lawsuit, a product going out of date. Cheap-looking stocks that keep getting cheaper are called value traps.
It can't see the business changing. A DCF projects the past forward. If the business itself is being disrupted, history is a poor guide.
How to use it
Intrinsic value works best as one input in a broader process, not as a verdict.
Think in scenarios, not single numbers. SIA company dashboards show three DCF scenarios side by side: one using the company's own historical growth, one using the average growth of its sector, and one using analysts' growth estimates. When the three land close together, the estimate is more robust. When they are far apart, the assumptions are doing most of the work.
Demand a margin of safety. Because the estimate can be wrong, many value investors only buy well below it. SIA dashboards show a margin-of-safety price 30% below each DCF scenario for this reason.
Check quality first. A precise valuation of an unpredictable business is worth little. Return on invested capital, debt levels and the consistency of free cash flow tell you whether the projections are reasonable in the first place.
Run the numbers yourself. Changing the growth rate and discount rate by hand is the fastest way to see how fragile or sturdy an estimate is. The SIA valuation suite includes a DCF calculator for exactly this.
Frequently asked questions
Is intrinsic value the same as book value?
No. Book value is an accounting figure: assets minus liabilities on the balance sheet. Intrinsic value looks forward at the cash a business will produce. A strong brand or software business can be worth many times its book value, while a struggling manufacturer can be worth less.
Why do different websites show different intrinsic values for the same stock?
Because they use different assumptions for growth, discount rate and terminal value, and sometimes different methods altogether. The differences are a useful reminder that intrinsic value is an estimate, not a fact.
What discount rate should I use?
Many investors use something between 8% and 12%. A higher rate makes sense for riskier or less predictable businesses, a lower one for very stable companies. The rate should reflect the return you genuinely require, not the one that produces a pleasing answer.
The bottom line
Intrinsic value is the anchor that keeps an investor focused on the business rather than the share price. Used as a range, tested against several assumptions and paired with a margin of safety, it brings clarity to a noisy market. Used as a single precise number, it gives false confidence.
