Intrinsic Value
The discounted present value of all cash a business will generate over its remaining life — the true economic worth independent of market price.
“Intrinsic value is an all-important concept that offers the only logical approach to evaluating the relative attractiveness of investments and businesses. Intrinsic value can be defined simply: It is the discounted value of the cash that can be taken out of a business during its remaining life.”
Concept Analysis
Definition & Origins
Intrinsic value is the present value of all cash that can be taken out of a business during its remaining life. It is the true economic worth of a business — the number that a perfectly rational, fully informed buyer would pay to own the entire enterprise as a private transaction, with no premium for control and no discount for illiquidity.
Buffett introduced his formal definition in the 1983 letter and has refined it through his concept of "owner earnings." The core insight: two businesses can have identical accounting earnings yet dramatically different intrinsic values, depending on how much capital each must reinvest to sustain those earnings. The business that earns $10 million requiring $5 million of reinvestment has $5 million in owner earnings; the one earning $10 million requiring zero reinvestment has $10 million in owner earnings. Their intrinsic values differ by a 2:1 ratio despite identical reported profits.
Core Ideas
Owner earnings, not accounting earnings. Buffett's formula (introduced explicitly in the 1986 letter): owner earnings = net income + depreciation/amortization − capital expenditures required to maintain competitive position and volume. Depreciation is a real economic cost (assets genuinely wear out) but not the precise measure of maintenance capex for every business. For a software company, maintenance capex may be near zero; for a railroad, it may equal or exceed reported depreciation.
The static vs. dynamic distinction. Intrinsic value is not a single number but a range, and it changes over time as competitive conditions evolve. A business whose intrinsic value is growing at 15% per year is more valuable than the same business growing at 5% per year, even if today's snapshot of cash flows is identical. Buffett's investing methodology is fundamentally dynamic — he is buying future cash flows, not today's balance sheet.
Margin of safety as the bridge between intrinsic value and purchase price. No intrinsic value estimate is perfectly accurate. Buying at a substantial discount to even a conservative intrinsic value estimate provides a buffer for analytical errors, unforeseen events, and competitive changes. The greater the certainty of the intrinsic value estimate, the smaller the required discount.
Practical Application
Book value as a faulty proxy. For asset-heavy, capital-intensive businesses (steel mills, airlines), book value approximates intrinsic value reasonably well. For asset-light businesses with strong brand or network advantages (Coca-Cola, American Express), intrinsic value can be multiples of book value — because the primary productive assets (brand equity, customer relationships) don't appear on balance sheets. Berkshire stopped using book value as its primary metric precisely because the gap had grown too large.
The look-through earnings framework. For businesses Berkshire owns partially through equity securities, determining true intrinsic value requires "looking through" to the company's full earnings — not just the dividends received — and assessing what Berkshire's proportionate share of retained earnings will generate in future value.
Common Misconceptions
Misconception 1: Intrinsic value can be precisely calculated. It is always an estimate within a range. The apparent precision of DCF models — with specific discount rates and exact growth assumptions — is false precision that overstates analytical confidence. Buffett's preference: a rough but defensible estimate of intrinsic value using conservative assumptions, with a large margin of safety to protect against errors.
Misconception 2: A low P/E ratio indicates intrinsic value is above price. P/E is a starting point, not a conclusion. A 10x P/E on a business that requires ongoing capital investment at below-market returns is not cheap. A 25x P/E on a business that can compound earnings at 20% for decades with minimal capital requirements may be the better value.
Misconception 3: Market price reflects intrinsic value in the short run. The Mr. Market allegory exists precisely to reject this. In the short run, prices are determined by investor psychology — fear, greed, narrative momentum. In the long run, share prices converge toward intrinsic value. The investment advantage comes from exploiting the gap between these two, which requires the ability to estimate intrinsic value independently of current market sentiment.
