In 1986, Warren Buffett sat down to write his annual letter to Berkshire Hathaway shareholders and buried, deep inside, a single paragraph that would change how serious investors around the world read an income statement. He introduced a concept he called “owner earnings” — a number he argued was more honest, more economically meaningful, and more useful for valuation than the net profit printed at the top of every annual report. Nearly four decades later, in April 2026, the same formula remains one of the most underused analytical tools in Indian investing. Most retail investors in India still anchor to reported Profit After Tax (PAT). This article explains, step by step, why Buffett called PAT an incomplete picture, how to calculate owner earnings in the Indian context using Ind AS financials, and what the numbers reveal when you apply it to four very different Indian businesses: Asian Paints, Pidilite Industries, Nestlé India, and Titan Biotech.
What Buffett Actually Said in 1986 — And Why It Matters
Buffett’s concern was straightforward. Generally Accepted Accounting Principles (and their Indian equivalent, Ind AS) require companies to report a net profit figure that includes non-cash charges (depreciation, amortisation) and ignores cash the business must spend every year just to stay in the same competitive position (maintenance capital expenditure and working-capital build-up). Two companies could report identical net profit, yet one might need to reinvest almost all of it just to keep the lights on, while the other could hand nearly the entire amount to shareholders. Reported earnings treat these two businesses the same. Owner earnings do not.
In his own words from the 1986 letter: “If we think through these questions, we can gain some insights about what may be called ‘owner earnings.’ These represent (a) reported earnings plus (b) depreciation, depletion, amortization, and certain other non-cash charges … less (c) the average annual amount of capitalized expenditures for plant and equipment, etc. that the business requires to fully maintain its long-term competitive position and its unit volume.”
The principle sits at the heart of what Charlie Munger and Buffett call “second-level thinking” about accounting — looking past the number that accountants produce to the number an owner of the whole business would actually pocket. It is a foundational principle of value investing alongside Graham’s margin of safety, Fisher’s scuttlebutt, and Lynch’s six categories.
The Formula, Adapted for Indian Financial Statements
Indian listed companies publish their accounts under Ind AS. Every annual report has three statements you will need: the Statement of Profit & Loss, the Statement of Cash Flows, and the notes on property, plant and equipment. The owner-earnings formula, translated into the line items you will actually see, is:
Profit After Tax (from P&L)
+ Depreciation & Amortisation (add back — non-cash charge)
+ Other non-cash charges (impairment, share-based comp, deferred tax, etc.)
− Maintenance Capital Expenditure (cash needed to preserve existing earning power)
− Incremental Working Capital (cash tied up in receivables and inventory to sustain current sales)
The hardest line is maintenance capex. Indian annual reports do not separate maintenance capex from growth capex. Buffett himself admitted this is an “inherently subjective” estimate. Three practical approaches analysts use in India:
Approach 1 — Depreciation proxy. Assume maintenance capex approximately equals annual depreciation. This works for mature businesses with stable asset bases but understates maintenance for high-growth companies whose fixed assets are new and whose future maintenance needs will be higher than today’s depreciation.
Approach 2 — Bruce Greenwald method. Estimate average gross PP&E per unit of sales across several years, then multiply the increase in sales by that ratio to get growth capex; everything else in total capex is maintenance.
Approach 3 — Conservative total-capex method. Subtract total capex (maintenance + growth). This penalises companies in growth mode but is the safest assumption when maintenance capex cannot be reliably separated. For teaching purposes it is the cleanest starting point.
Four Indian Case Studies — FY25 Numbers Side by Side
Below is the same calculation applied identically to four Indian businesses for FY2025 (year ended March 2025), using publicly reported numbers from Screener.in and each company’s annual report. All figures are in ₹ crores. The “Owner Earnings (conservative)” column uses Approach 3 — total capex subtracted — which is why it sometimes looks harsh.
| Company | Net Profit | + D&A | − Capex | = Owner Earnings | OE ÷ Net Profit |
|---|---|---|---|---|---|
| Asian Paints Ltd | ₹3,710 | ₹1,026 | ₹941 | ₹3,795 | 102% |
| Pidilite Industries Ltd | ₹2,096 | ₹358 | ₹1,542 | ₹912 | 44% |
| Nestlé India Ltd | ₹3,208 | ₹540 | ₹2,004 | ₹1,744 | 54% |
| Titan Biotech Ltd | ₹22 | ₹4 | ₹10 | ₹16 | 73% |

Asian Paints — the textbook mature compounder
Depreciation (₹1,026 Cr) is almost identical to annual capex (₹941 Cr), a hallmark of a mature business where growth capex is modest and the plant base is near steady state. Owner earnings of ₹3,795 Cr actually exceed reported net profit of ₹3,710 Cr — because depreciation, a non-cash charge, slightly exceeds the cash spent on property, plant and equipment. This pattern is what Buffett, Nick Train, and Terry Smith look for in quality compounders: earnings that convert nearly one-for-one into distributable cash.
Pidilite — growth-capex distortion
Pidilite’s capex of ₹1,542 Cr dwarfs its depreciation of ₹358 Cr, indicating heavy investment in new capacity — new manufacturing lines, the B2B construction chemicals business, acquisitions. Using the conservative total-capex approach, owner earnings of ₹912 Cr are less than half of reported PAT of ₹2,096 Cr. This is not a negative signal by itself — growth capex today builds cash flows tomorrow — but it is a crucial fact. An investor studying Pidilite must form a view on whether that growth capex will earn its cost of capital. Without that view, using reported PAT alone overstates the business’s current shareholder-distributable earnings.
Nestlé India — expansion phase
Nestlé’s heavy capex (roughly ₹2,004 Cr in FY25, implied from published free cash flow of ₹932 Cr and operating cash flow of ₹2,936 Cr) reflects the new Odisha plant and ongoing capacity additions across the MAGGI, Nescafé, and nutrition portfolios. Owner earnings of ₹1,744 Cr against reported PAT of ₹3,208 Cr reveal that close to half of current reported profit is being reinvested rather than distributed. Investors who study Nestlé must ask: will those new plants compound book value faster than simple distribution would? That is the classic Akre three-legged stool question — business quality, management, and runway.
Titan Biotech — the small-cap adjustment
Titan Biotech is a microcap biological-products maker with FY25 sales of ₹156 Cr and a tight, focused asset base. Capex of ₹10 Cr versus depreciation of ₹4 Cr indicates modest growth investment. Owner earnings of roughly ₹16 Cr represent about 73% of reported PAT — a healthy pass-through ratio for a company still scaling. This row illustrates that the same formula works at every size of business, from ₹1,961 Cr market cap to ₹2.33 lakh crore giants. Nothing about owner earnings requires the company to be large; what it requires is honest cash-flow arithmetic. (Note: this is an educational walk-through, not a view on Titan Biotech’s business prospects or stock; see the disclaimer at the end.)
The Owner-Earnings Research Checklist
Here is how any retail investor in India can apply owner earnings to any listed company before forming an opinion. This is a research checklist, not a buy-or-sell recommendation. Its purpose is to help you think like an owner, not to tell you which stocks to own.
Step 1 — Pull five years of data. One year of capex is noisy. Compute owner earnings for each of the last five fiscal years and look at the average and trend. A single large year of capex can distort a quality business temporarily.
Step 2 — Decompose capex into maintenance vs. growth. Read the notes to fixed-asset additions. Look at new-plant commissioning disclosures. Check the Management Discussion & Analysis for capex guidance. If a company says “we spent ₹500 Cr on a new greenfield plant,” that is growth capex; the steady-state depreciation charge is a better guide to what maintenance actually costs.
Step 3 — Add back non-cash items beyond depreciation. Look for impairment losses, share-based compensation (ESOP charges), and deferred tax movements. Each of these is a real number in the P&L that does not immediately affect cash.
Step 4 — Subtract incremental working capital. From the cash-flow statement, take the increase in trade receivables, increase in inventories, and decrease in trade payables. This is cash the business had to commit to support sales growth.
Step 5 — Compare owner earnings to reported PAT and to free cash flow. If the three numbers are close, the business converts earnings into cash efficiently. If owner earnings are meaningfully below PAT, ask what is consuming the cash. If owner earnings exceed PAT, check whether depreciation is structurally higher than maintenance requirements.
Step 6 — Track the trend over five to ten years. A business whose owner earnings are growing faster than reported earnings is becoming more cash-generative. The reverse is a yellow flag.
Common Pitfalls When Applying Owner Earnings in India
Pitfall 1 — Mistaking growth capex for maintenance capex in young companies. Penalising a fast-growing business for its growth capex will systematically understate its true earning power. The fix: study the MD&A, call management if accessible, and separate the two components.
Pitfall 2 — Ignoring acquisitions. Cash spent on acquiring other companies is another form of reinvestment. If a business routinely acquires, a complete owner-earnings picture must decide how to treat that cash. The Francois Rochon “owner’s mindset” view is to include serial bolt-on acquisitions as a form of maintenance capex if they are essential to maintain competitive position.
Pitfall 3 — Anchoring to one year. A single year of heavy capex, a one-off working-capital build-up, or a one-time tax adjustment can make a high-quality business look terrible — or vice versa. Always use multi-year averages.
Pitfall 4 — Confusing owner earnings with free cash flow. Free cash flow (OCF minus total capex) is a closely related but different metric. Owner earnings attempt to estimate normalised cash-generating ability, while free cash flow is an actual historical reported number. Both are useful; they answer different questions.
Pitfall 5 — Treating the output as a valuation verdict. Owner earnings are an input into thinking, not a conclusion. Two analysts looking at the same owner-earnings figure for the same company can reasonably disagree about whether the stock is attractive, because valuation also requires assumptions about growth, competitive durability, and required rate of return.
Why This Principle Sits Alongside Margin of Safety and Moats
Value investing has never been about a single formula. Graham gave investors the margin of safety. Buffett added the economic moat and then, in 1986, owner earnings. Phil Fisher contributed scuttlebutt; Peter Lynch gave the six categories of stocks; Howard Marks added second-level thinking and market cycles; Munger contributed the mental-models lattice. Owner earnings are not a replacement for any of these — they are a lens. Used together with moats (does the business have a durable competitive advantage?), with margin of safety (is the price you pay well below your estimate of intrinsic value?), and with circle of competence (do you actually understand the business?), owner earnings help you avoid overpaying for companies whose reported profits overstate their cash-distribution ability, and help you recognise quality in companies whose growth reinvestment temporarily depresses their headline PAT.
The beauty of the Buffett framework is that it is available to any retail investor in India with nothing more than a screener.in account, a PDF of the annual report, and patience. The math is arithmetic; the judgment is where the work lies. That is precisely the kind of work that rewards decade-long holders of quality businesses and filters out speculators chasing quarterly headlines.
Key Takeaways
Owner earnings, introduced by Warren Buffett in the 1986 Berkshire Hathaway letter, adjust reported net profit by adding back non-cash charges and subtracting the cash required to maintain existing earning power. The four Indian examples above — Asian Paints, Pidilite, Nestlé India, and Titan Biotech — show how the same arithmetic reveals very different cash-conversion profiles: Asian Paints converts reported earnings almost entirely into distributable owner earnings; Pidilite and Nestlé India reinvest heavily and therefore have current owner earnings well below PAT; Titan Biotech, at the small end of the size spectrum, shows a respectable pass-through at modest growth capex. None of these figures is a recommendation. They are an input into the patient, multi-factor judgment that value investors have practised since Benjamin Graham wrote Security Analysis in 1934.
