Calculating Intrinsic Value
What a business is actually worth, estimated from its own numbers — as distinct from whatever Mr. Market happens to be quoting today.
Intrinsic value is what a business is objectively worth, based on its assets, earnings power, and reasonable future prospects — separate and often different from whatever price it happens to be quoted at right now. Graham is explicit that this is always an estimate, a reasonable range rather than one precise figure, and that false confidence in an overly precise-looking calculation is itself a real risk worth guarding against.
The actual raw material for that estimate is the company's own financial statements — the same three statements covered elsewhere on this site's Fundamentals track — read specifically with the goal of estimating what the whole business could reasonably be sold for, not just what this quarter's headline earnings number happens to say.
Several distinct inputs feed into any such estimate, and they don't all move it in the same direction with the same weight — some justify paying a higher multiple on the same earnings, others argue for more caution regardless of how good the headline number looks.
"Normalized" is doing most of the work here — taking a single unusually good or bad year's earnings at face value will distort the whole estimate.
| Input | Effect if stronger | Effect if weaker |
|---|---|---|
| Normalized earnings | Raises the estimate directly | Lowers the estimate directly |
| Earnings stability/predictability | Justifies a higher multiple on those earnings | Argues for a lower multiple, more caution |
| Balance-sheet strength | Supports more confidence in the estimate overall | Argues for a lower multiple, more caution |
| Growth prospects | Can justify paying a higher multiple today | Argues for a lower multiple, less benefit of the doubt |
Graham's own famous shortcut: you don't need to know a man's exact weight to know he's fat, or his exact height to know he's tall enough to play professional basketball. The same logic applies to valuing a business — you don't need to calculate intrinsic value to the exact dollar to recognize that a stock trading at a fraction of a conservative estimate is a genuine bargain. Chasing false precision in a valuation estimate is itself often a warning sign of overconfidence, not a sign of rigor.
A retailer with volatile, cyclical earnings reports $2.00/share in a boom year and $0.40/share in a weak one. Averaging several years of earnings, rather than extrapolating straight from the most recent unusually strong (or weak) year alone, gives a "normalized" earnings figure closer to the business's real, sustainable earning power — and a far more honest input into any valuation estimate built on top of it.
One conservative anchor Graham points toward: assume the business's current normalized earnings simply continue forever, with no growth at all, and ask what that no-growth earnings stream would be worth, capitalized at a reasonable rate. This separates what the existing, already-proven business is worth doing nothing more than what it already does, from any additional value attributed to future growth that hasn't actually shown up yet. Anything a buyer pays above that no-growth anchor is, implicitly, a bet on growth actually materializing.
A company earns a normalized $5/share, and that no-growth earnings stream, capitalized at a conservative rate, is worth roughly $50/share on its own. If the stock trades at $55, the market is pricing in only a modest amount of future growth above the no-growth anchor. If it trades at $150, the market is pricing in a great deal of future growth that hasn't yet actually happened — a materially more speculative bet, whether or not the buyer realizes that's what they're making.
- Intrinsic value is always a reasonable estimate or range, never a single precise figure — treating it as exact is a common, avoidable overconfidence trap.
- Normalizing earnings across several years, rather than using the most recent year alone, protects the estimate from being distorted by one unusually strong or weak period.
- A no-growth "earnings power value" anchor separates what a business is worth today from how much of the price is really a bet on future growth that hasn't happened yet.
- The whole purpose of estimating intrinsic value is to have an independent reference point — so Mr. Market's quoted price can actually be judged against something, instead of being taken at face value.
