Owner Earnings — The number that belongs to you
Worked example: Coca-Cola — 1988–2023
In January 1972, Blue Chip Stamps proposed paying $25 million for See's Candies — a California chocolate business with $4.2 million in annual earnings and $8 million in book value. By conventional metrics, the price looked steep: roughly six times book and six times earnings, at a time when most value investors searched for businesses at one or two times book. But Warren Buffett was not evaluating See's on those metrics. He was asking a different question: how much of the reported $4.2 million genuinely belonged to the owners?
For See's, the answer was nearly all of it. The business required almost no reinvestment to maintain its competitive position. Fixed assets were modest. Working capital requirements were minimal. The brand, the reputation, and the customer loyalty — the real source of See's earnings power — did not depreciate in any economically meaningful way. Every dollar of reported earnings was a genuine owner dollar.
Over the following 50 years, See's generated over $2 billion in cumulative owner earnings on that original $25 million investment, with minimal additional capital contributed. The price that looked expensive against book and reported earnings was in fact extraordinarily cheap against owner earnings, compounded forward. That insight became the formal concept of owner earnings, published in the 1986 Berkshire Hathaway annual report. It is the synthesis of everything the previous four valuation tools were building toward.
The concept in 60 seconds
Owner earnings is Buffett's refinement of free cash flow: the cash genuinely available to owners after every dollar required to maintain the business's competitive position has been spent.
The formula, as Buffett defined it in 1986: net income plus depreciation and amortization, minus the average annual capital expenditure required to maintain the business's competitive position, adjusted for working capital changes.
The critical element is the capex term — maintenance capex only, not total capex. Growth capex is optional. Management chooses whether to expand capacity, enter new markets, or fund acquisitions. That capital is not a requirement; it is a deployment decision. Only the capital that must be reinvested to prevent competitive deterioration counts against owner earnings.
This distinction creates four distinct business types. First, high owner earnings relative to reported earnings: capital-light businesses — brands, software, professional services — where depreciation and amortization overstates actual economic asset decay and maintenance capex is minimal. Owner earnings exceed reported earnings. Second, owner earnings roughly equal to reported earnings: businesses where D&A accurately reflects genuine asset decay and maintenance capex matches it. Reported earnings are a faithful proxy. Third, low owner earnings relative to reported earnings: capital-intensive businesses — steel, utilities, airlines, chemicals — where required capex consistently exceeds D&A. Reported earnings overstate the cash genuinely available to owners. Fourth, negative owner earnings despite positive reported earnings: businesses in capital-intensive industries under secular pressure, where maintaining any competitive position requires accelerating reinvestment as earnings erode.
The valuation implication is direct: a P/E multiple applied to a capital-light business and the same multiple applied to a capital-intensive business represent fundamentally different things. One prices genuine earning power. The other prices reported earnings that must largely be recycled back in.
Mental model
Think of owner earnings as the answer to one question: if this business stopped growing entirely, how much cash could it reliably distribute to owners every year without impairing its competitive position?
Growth capex is excluded because growth is a choice. Management can decide not to expand, and the business would continue earning. Maintenance capex is included because it is not a choice — skip it, and the business deteriorates. Owner earnings is the number that exists in the absence of growth ambition.
This framing has a critical implication for valuation: growth only adds value if the returns on growth investment exceed the cost of capital. A business retaining all of its owner earnings and reinvesting at 6% creates no economic value for owners if the required return is 10%. Its intrinsic value equals current owner earnings divided by the required rate of return — a zero-growth perpetuity. Value is only created when incremental returns on reinvestment exceed the hurdle rate. High owner earnings with poor reinvestment opportunities is worth the perpetuity. High owner earnings with exceptional reinvestment opportunities is worth a multiple of the perpetuity.
The hardest part of the calculation is estimating maintenance capex. There is no line item on any financial statement that says "this is what we must spend." Buffett acknowledged this explicitly in the 1986 letter: the number requires judgment, and the judgment is the work. For capital-light businesses with clear brand or intellectual property moats, estimation is relatively straightforward — maintenance capex is small and bounded. For capital-intensive businesses, distinguishing growth from maintenance requires industry knowledge and pattern recognition across multiple years of capex and operating performance.
Worked example: Coca-Cola, 1988–2023
When Buffett began buying Coca-Cola shares in late 1988, the stock traded at roughly 15 times reported earnings — not an obvious bargain by any standard screen. What made it compelling was the owner earnings analysis.
Coke's business in 1988 was capital-light in a specific and powerful way. The brand, the syrup formula, and the global distribution relationships required almost no ongoing capital reinvestment to maintain. The physical assets — bottling equipment, delivery infrastructure — were mostly owned by the independent bottlers, not Coke itself. Coke's own capital expenditure was modest relative to earnings, and depreciation charges were similarly modest and roughly matched genuine economic asset decay.
The result: Coke's owner earnings in 1988 were approximately equal to its reported earnings. There was no capex trap — reported earnings were genuine owner earnings. And those owner earnings were growing at approximately 15% per year, driven by pricing power and international expansion.
At 15 times reported earnings, Buffett was effectively paying approximately 15 times owner earnings for a business compounding at 15% annually. Over a 10-year horizon at that growth rate, the effective purchase multiple was closer to 4 times year-10 owner earnings — an implied long-term earnings yield of approximately 25%. That calculation justified aggressive buying.
| Year | Reported Earnings | Est. Owner Earnings | P/OE | What the market was pricing |
|---|---|---|---|---|
| 1988 | ~$1.0bn | ~$1.0bn | ~15× | A mature beverage company at a cyclical multiple |
| 1993 | ~$2.2bn | ~$2.3bn | ~20× | Initial franchise recognition; premium begins forming |
| 1998 | ~$3.5bn | ~$3.7bn | ~35× | Full re-rating complete; Buffett slows his buying |
| 2008 | ~$5.8bn | ~$6.0bn | ~17× | Crisis repricing; franchise business entirely unchanged |
| 2023 | ~$10.7bn | ~$11.2bn | ~23× | 35 years: owner earnings up approximately 11× from entry |
The lesson is not that Coke was cheap in 1988 because of a low P/E — it was not. The lesson is that it was cheap on owner earnings relative to its growth rate, and the market was pricing it as something far more ordinary than what it was. The owner earnings lens revealed the gap between accounting representation and economic reality.
Historical pattern
1930s–1960s: Graham's earnings power — the precursor. Benjamin Graham's concept of earnings power value — the value of a business based on sustainable, normalized earnings stripped of cyclical distortions — was the intellectual precursor to owner earnings. Graham focused on what a business could reliably earn over time, but he did not explicitly address the capex adjustment that distinguishes reported earnings from owner earnings. The separation of maintenance from growth capital would have to wait another 50 years.
1970s: Inflation and the capital trap. The inflation of the 1970s revealed the gap between reported earnings and owner earnings in capital-intensive industries with unusual force. Depreciation charges were calculated on historical cost — but replacing equipment in an inflationary environment required spending at current replacement cost, which was dramatically higher. A steel mill reporting $10 million in annual depreciation might require $30 million in real capex simply to maintain productive capacity. Owner earnings for these businesses were a fraction of reported earnings. The P/E ratios that looked cheap in the early 1970s were not cheap on owner earnings — and investors who failed to make the distinction suffered accordingly.
1986: Buffett formalizes the concept. In approximately 500 words in the Berkshire Hathaway 1986 annual report, Buffett published his definition and explanation of owner earnings. He was explicit about its imprecision — the maintenance capex estimate involves judgment and cannot be read from any financial statement — and explicit about why it matters: reported earnings conflate the capital required to survive with the capital available to owners. The distinction is the difference between what a business earns and what it is worth.
1990s–2000s: Technology and the owner earnings premium. The rise of software and internet businesses created a new category: businesses with large accounting depreciation charges — from capitalized software development and server infrastructure — but minimal genuine maintenance requirements. For these businesses, reported earnings dramatically understated owner earnings. The D&A charge reflected accounting rules applied to software assets; the actual economic cost of maintaining a franchise like Windows or Oracle's database was a fraction of the accounting charge. Investors who analyzed these businesses on reported P/E systematically mispriced their genuine earning power. Owner earnings substantially exceeded reported earnings, and the firms were far cheaper than they appeared on standard screens.
2010s–present: Stock-based compensation as the new distortion. The most significant modern challenge to owner earnings calculations is stock-based compensation. SBC is a real economic cost — it dilutes existing shareholders — but is excluded from most companies' preferred operating earnings and adjusted cash flow figures. A technology company generating $2 billion in operating cash flow while issuing $1.5 billion in annual SBC is producing approximately $500 million in genuine owner earnings. The adjustment is straightforward in principle; the resistance to making it in practice is widespread. Analysts who accept management's "adjusted" earnings figures without restoring the SBC cost overstate owner earnings and consequently overpay.
Decision framework
Step 1 — Start with net income and add back D&A. Take reported net income from the income statement. Add back depreciation, amortization, and any other significant non-cash charges. This gives you the pre-maintenance-capex owner earnings baseline — a number that removes accounting smoothing from the cash picture.
Step 2 — Estimate maintenance capex. This is the judgment call. There is no disclosed maintenance capex line. For capital-light businesses, look at years of minimal capex investment and observe whether competitive position held — that establishes a lower bound. For capital-intensive businesses, compare long-run capex to D&A: if capex consistently exceeds D&A by 30% or more over a full cycle, the excess is likely mandatory rather than discretionary growth. Cross-reference with management guidance on maintenance vs. growth spending, then test whether operating results in low-capex years support the maintenance-only thesis.
Step 3 — Adjust for stock-based compensation. Add SBC back as a cost against owner earnings. It does not appear in capex and is not captured in cash flow from operations in the way other costs are — but it is absolutely a real economic cost. Shareholders are being diluted. The dilution has economic value transferred from existing owners to employees. A business distributing $500 million in annual SBC on $1 billion in operating cash flow is generating approximately $500 million in genuine owner earnings, not $1 billion.
Step 4 — Compare owner earnings to reported earnings and to FCF. Owner earnings should typically sit between reported earnings and free cash flow for most businesses. If owner earnings is materially higher than FCF, management may be classifying maintenance spending as growth capex — inflating the owner earnings calculation. If owner earnings is dramatically lower than reported earnings, the business has a structural capex requirement that the income statement obscures. Either significant divergence from the triangulated expectation requires explanation and investigation.
Step 5 — Apply owner earnings to valuation. Divide the current market price by owner earnings per share to get the price-to-owner-earnings multiple. Compare to the required rate of return and to estimated long-term growth. A business at 10 times owner earnings with 10% expected growth is worth investigating seriously. A business at 30 times owner earnings with 8% expected growth must sustain that growth for over two decades before the return justifies the price. The math is unforgiving — do it explicitly rather than relying on narrative.
Common mistakes
Deducting total capex instead of maintenance capex. This is the most common error and systematically undervalues quality growth businesses. A company investing heavily to expand capacity, enter new markets, or acquire customers is making growth investments that will generate future owner earnings. Deducting all capex assigns zero value to that future earning power. For a rapidly growing business with high returns on investment, calculated owner earnings using total capex will dramatically understate genuine owner earning power.
Ignoring stock-based compensation as a real cost. SBC dilutes existing owners and represents real economic value transferred from shareholders to employees. Excluding it from owner earnings calculations overstates the genuine cash available to owners and the intrinsic value of the business. The fact that SBC is non-cash does not make it less real — it means the cost is paid in equity rather than cash, which is worse for existing owners because it permanently reduces their percentage ownership.
Assuming owner earnings always exceeds free cash flow. For capital-light businesses this is typically true. But for a capital-intensive business with a genuine growth program, free cash flow may be lower than owner earnings only because growth capex is large. Remove the growth capex and owner earnings may be quite modest. The relationship between owner earnings and FCF depends entirely on how much the business is choosing to invest in growth versus what it must invest to stand still.
Applying a single P/OE multiple without considering reinvestment returns. Owner earnings yield is only half the valuation equation. A business with a 6% owner earnings yield reinvesting at 20% returns is worth far more than one with the same yield reinvesting at 8%. Intrinsic value is the present value of all future owner earnings — not just this year's. A low yield with exceptional reinvestment opportunities justifies a high multiple. A high yield with no reinvestment opportunity above the hurdle rate justifies only the no-growth perpetuity value: owner earnings divided by the required return.
How VI Stack uses this
Owner earnings is the final and integrating valuation lens in Gate 3 — The Forensics. It comes last in the five-step sequence because it requires the other four as inputs: P/E establishes the earnings baseline, EV/EBITDA provides the enterprise-level view, FCF identifies cash conversion quality, and book value establishes the asset foundation. Owner earnings synthesizes those observations into a single, integrated picture of what the business genuinely generates for its owners.
In Gate 3, owner earnings is reconciled against all four other valuation measures. Where owner earnings diverges significantly from reported earnings or FCF, the analysis identifies the cause: maintenance capex classification, SBC treatment, working capital dynamics, or a genuine earning power problem. The reconciliation between all five measures is the quality check — a business where all five converge is telling a consistent story; a business where they diverge significantly demands explanation.
In Gate 4 — The Pitch — the intrinsic value calculation uses normalized owner earnings as its primary input: a sustainable owner earnings figure, a growth assumption grounded in the business quality analysis, and a discount rate appropriate to the risk profile. The resulting intrinsic value is compared against the current market price to establish margin of safety. Owner earnings is the numerator in that calculation.
In Gate 5 — The Advisory Board — the owner earnings assumptions are stress-tested directly: what maintenance capex estimate is embedded in the calculation, what happens if a portion of classified growth capex turns out to be maintenance, and what does the business generate in a zero-growth scenario? The board's challenge is to find the assumptions that break the investment thesis — and owner earnings is usually where that challenge cuts deepest, because the maintenance capex estimate is always a judgment call.
What's next
The Valuation series is complete. With owner earnings, the five-lens framework for appraising a business — Price-to-Earnings, EV/EBITDA, Free Cash Flow, Book Value, and Owner Earnings — is fully assembled. Each lens asks a different question: what is the market paying for earnings, for the enterprise, for cash generation, for assets, and for the genuine distributable economics of the business. Used together, they triangulate around intrinsic value and reveal where the market's pricing diverges from underlying economic reality.
bq-01 — The Five Types of Moat opens the Business Quality series. A business can only sustain owner earnings growth if its competitive advantage is durable enough to protect pricing power and market position over the long term. Understanding what kind of moat a business has, how wide it extends, and how likely it is to hold for five, ten, or twenty years is the foundation for deciding whether today's owner earnings can compound forward. That is the next question.
