Owner Earnings
In the 1986 Letter (specifically the Appendix), Buffett introduces Owner Earnings as the definitive measurement of a business's economic performance, arguing that GAAP (Generally Accepted Accounting Principles) net income is often misleading.
🧮 The Formula
Buffett defines owner earnings as:
- Reported Earnings
- PLUS Depreciation, Amortization, and other non-cash charges
- MINUS Average annual amount of Capital Expenditures (CapEx) required to maintain long-term competitive position and unit volume.
Owner Earnings = (Net Income + Depreciation/Amortization) - Maintenance CapEx
🏗️ Why it Matters
- GAAP Flaws: GAAP allows managers to ignore the "lumpy" costs of replacing worn-out equipment if they have already "expensed" it through depreciation. However, in an inflationary environment, the actual cost of replacing that equipment is often much higher than the historical depreciation charge.
- Maintenance vs. Growth CapEx: Buffett distinguishes between capital spent to stay in business (Maintenance) and capital spent to expand (Growth). Only Maintenance CapEx should be subtracted to find the earnings available to the owner.
- Economic Reality: For a "Wonderful Business" (like See's Candies), owner earnings are often higher than reported earnings because the business requires very little capital to maintain its position. For a "Troubled Business" (like the old textile mills), owner earnings are often zero or negative, because every dollar earned must be immediately plowed back into new machinery just to stay alive.
- Purchase Price Accounting: In the 1986 Letter, Buffett explains how the "Step-up in Basis" associated with acquiring companies like Scott Fetzer Co. created massive non-cash amortization charges. These charges reduced GAAP net income but had zero impact on owner earnings (since they weren't actual cash outflows). Thus, owner earnings in 1986 perfectly illustrated the "hidden" profitability of Berkshire's subsidiaries.
📉 Relation to Free Cash Flow
Owner Earnings is closely related to what Wall Street calls "Free Cash Flow," but Buffett’s definition is more nuanced because it focuses on the required maintenance capital rather than just what was spent in a single year.

🌱 Idea Evolution & Maturity
How this concept developed over time, tracking its transformation from an early practice to a formalized Berkshire pillar.
Implicit Cash Flow Focus
Buffett begins manually adjusting reported earnings for his own valuation models to ignore non-cash amortization.
Accounting numbers are just a starting point; the investor's job is to figure out the actual cash a business generates.
Accounting numbers, of course, are the language of business... but they are not the end of the analysis.
Formal Equation
Buffett formally coins the term 'Owner Earnings' and provides the exact formula: Net Income + Depreciation/Amortization - Average Capital Expenditures.
A formal rejection of GAAP net income and Wall Street's cash flow (which ignores CapEx). True earnings are what an owner can extract without harming the business.
Owner earnings represent (a) reported earnings plus (b) depreciation... less (c) the average annual amount of capitalized expenditures for plant and equipment.
Valuation Benchmark
Owner Earnings is weaponized as the ultimate defense against the rising popularity of EBITDA. It explicitly requires subtracting maintenance capital expenditures.
Ignoring CapEx is a fatal flaw in analysis. 'Does management think the tooth fairy pays for capital expenditures?'
References to EBITDA make us shudder... it implies that depreciation is not a real expense.
Fundamental Axiom
Owner Earnings is the unquestioned baseline for every intrinsic value calculation at Berkshire.
The concept is fully mature, serving as the definitive answer to any accounting manipulation or modern metric like 'adjusted earnings'.
We care only about what a business can generate in cash over its life, discounted back to today.
