Return on Equity, and What It Hides
One company is cheaper on P/E and more expensive on price-to-book than another. How can both be true?
2.3Return on Equity, and What It Hides3 of 4
3.1 — Same money doubled in year one, crawled by year four
Meera and Arjun put ₹6 lakh of their own savings into Sunrise Bakery. Year one, the bakery earns ₹6 lakh. They've just doubled their money in twelve months — a 100% return on what they put in.
Fast forward to year four. The bakery has kept most of its profits inside the business instead of paying them out, so the owners' stake has grown to ₹30 lakh. That same bakery now earns ₹9 lakh a year — more money than ever. Return on the owners' stake: 30%.
Bigger profit. Much lower return. Both true at once, and nothing went wrong. This is return on equity — profit divided by the owners' own money in the business — and it's the ratio that tells that difference apart when a bigger number alone would hide it.
3.2 — Why Reliance's profit climbed and its return barely did
Same pattern, six zeros bigger. Here's Reliance's own numbers from chapter 1 of this module.
| Year | Net profit | Net worth | Return on equity | Return on capital |
|---|---|---|---|---|
| FY2023 | ₹66,702 cr | ₹8,21,153 cr | 8.1% | 8.7% |
| FY2024 | ₹69,621 cr | ₹7,93,481 cr | 8.8% | 9.4% |
| FY2025 | ₹69,648 cr | ₹8,43,200 cr | 8.3% | 8.7% |
| FY2026 | ₹80,775 cr | ₹9,04,030 cr | 8.9% | 9.2% |
Profit up 21% across four years. Net worth up 10%. Return on equity budged less than a point — because the pile of money working underneath the profit grew almost as fast as the profit did. It's Sunrise Bakery's story exactly, with more commas.
3.3 — The harder-to-fake version
Return on capital employed asks the same question over a wider pool — everything the business runs on, borrowed money included, not just the owners' slice.
Because debt now sits in the denominator too, taking on more of it doesn't automatically flatter the number. That makes it the better read on whether the underlying business is actually good — and reading the two side by side tells you more than either alone.
- **Return on capital well above return on equity** — unusual. Usually means very little debt and cash sitting idle.
- **The two sitting close together** — modest borrowing. Reliance: 9.2% and 8.9% in FY2026, debt to equity 0.41.
- **Return on equity well above return on capital** — leverage doing the heavy lifting. It amplifies gains, and it amplifies losses just as fast.
Reliance's two numbers have tracked within half a point of each other for four straight years, alongside a stable debt load. That consistency is itself the finding — the returns are coming from the business, not from quietly changing how it's financed.
3.4 — What counts as "good"?
There's a real floor here, and it isn't zero. Money sitting in a plain fixed deposit earns something with almost no risk attached. A business returning less than that on its owners' money is quietly destroying value, however big the headline profit looks.
Above that floor, the number is shaped entirely by the industry, and comparing across industries is close to meaningless.
- **Businesses that need almost no equipment** — software, some consumer brands — routinely clear 25% and it's nothing special.
- **Businesses that need enormous fixed assets first** — refineries, power, telecom towers — can be doing well at high single digits.
Reliance's 8.9% is a solid figure for a refining-retail-telecom group sitting on ₹21.8 lakh crore of assets. It would be a weak figure for a software company. Same number, opposite verdict, depending entirely on what kind of business is behind it.
3.5 — The identity that explains chapter 2's loose end
Chapter 2 left you with a puzzle. Chennai Petroleum trades at 5.68 times earnings against Reliance's 20.31 — far cheaper. But on price-to-book, Chennai Petroleum is at 2.11 and Reliance at 1.88 — more expensive. How can one company be both cheaper and pricier than the other at once?
Because the three ratios aren't three separate facts. They're locked together by exact arithmetic:
P/B = P/E × ROE
The identity linking the three ratios
Exact algebra, not an approximation. Return on equity is earnings ÷ book value, so P/E × (earnings ÷ book) = price ÷ book.
| Company | P/E | × ROE | = computed P/B | Filed P/B |
|---|---|---|---|---|
| Chennai Petroleum | 5.68 | 37.1% | 2.108 | 2.11 |
| Mangalore Refinery | 8.14 | 26.6% | 2.169 | 2.17 |
| Reliance Industries | 20.31 | 9.3% | 1.882 | 1.88 |
| Kotyark Industries | 23.67 | 8.5% | 2.010 | 2.01 |
Puzzle solved. Chennai Petroleum's low P/E times its very high ROE multiplies out to a price-to-book slightly above Reliance's. Nothing contradicts anything — the market is charging less per rupee of TODAY's earnings and more per rupee of book value, because it doesn't expect that 37% return to last.
3.6 — Where this sits on EquityTale
Return on equity and return on capital both sit on every company page, and both feed into the Profitability and returns pillar of the Health Score — the biggest single weight of the six, 25 of 100 points, because it comes closest to directly measuring whether a business is any good at its job.
Reliance scores 39.9 out of 100 on it — a percentile against every company we score, not a mark out of a hundred. A capital-heavy group earning 8.9% will sit below the midpoint of a universe that also includes asset-light businesses earning 30%. That's a fact about what the measure is built to compare, not a verdict that the company is badly run.
One score built from six very different measures, squeezed into a single number — which is exactly the tension the next chapter walks straight into.
Key takeaways from this chapter
- 1.Return on equity is profit attributable to owners, divided by the owners' money. Use the owners' figure, not headline net profit.
- 2.A growing profit can leave the return flat if the capital employed grows too. Reliance's profit rose 21% from FY2023 to FY2026 and its return on equity moved 8.1% to 8.9%.
- 3.Money deployed today enters the denominator immediately and the numerator years later, which is why heavy reinvestment depresses returns temporarily.
- 4.Return on equity rewards borrowing without saying so — less equity for the same assets makes the same profit look like a better return.
- 5.Return on capital employed uses all long-term money, borrowed and owned, so it is harder to flatter with debt.
- 6.The two close together, as Reliance's 8.9% and 9.2% are, means returns are coming from the business rather than from financing.
- 7.A fixed deposit sets the floor. A business returning less than that on owners' money is destroying value however large its profit.
- 8.Above the floor, judge returns by industry. Asset-light businesses at 25%+ and capital-heavy ones in high single digits can both be doing well.
- 9.P/B = P/E × ROE, exactly. It follows from the definitions, and it holds on every company in Reliance's peer group that has a P/E.
- 10.Because that identity is exact, any two of the three ratios determine the third — so quoting all three adds nothing, and screening on several at once over-constrains.
Common questions
What is return on equity?
Profit attributable to the owners, divided by the owners' money in the business — the capital originally subscribed plus all profit retained since. It answers what return the shareholders earned on their stake, rather than how large the profit was.
Why did Reliance's profit grow while its return on equity stayed flat?
Because the capital employed grew almost as fast. Net profit rose from ₹66,702 crore in FY2023 to ₹80,775 crore in FY2026, up 21%, while net worth rose from ₹8,21,153 crore to ₹9,04,030 crore. Profit earned on a proportionately larger base leaves the return roughly unchanged.
What is the difference between return on equity and return on capital?
Return on equity measures profit against the owners' money only. Return on capital employed measures it against all long-term funding, borrowed as well as owned. Because debt sits in the denominator of the second, borrowing doesn't automatically flatter it — which makes it the better read on the underlying business.
Is a high return on equity always good?
Not necessarily. It can reflect a genuinely excellent business, or an unusually small equity base after large buybacks, sustained losses or heavy borrowing. A figure far above the industry norm is a reason to check the denominator, not a reason to stop looking.
How can a company be cheaper on P/E but more expensive on price-to-book?
Because the ratios are linked by exact arithmetic: price-to-book equals P/E multiplied by return on equity. Chennai Petroleum's low P/E of 5.68 combined with a 37.1% return on equity gives a price-to-book of 2.11, slightly above Reliance's 1.88 despite Reliance trading at 20.31 times earnings.
What counts as a good return on equity in India?
It depends entirely on the industry. Asset-light businesses such as software need little capital and routinely exceed 25%, while capital-heavy businesses such as refining or telecom infrastructure can be performing well in the high single digits. The one universal floor is that a return below what a fixed deposit pays is destroying value.
What this chapter rests on
- Reliance Industries filed annual figures — Net profit, net worth, return on equity, return on capital and debt to equity from exchange XBRL filings. FY2022 is absent from the filed series; FY2019 to FY2021 carry no equity figure.
- EquityTale peer computation — P/E, price-to-book and return on equity for the Refineries & Marketing peer group at the 11 September 2026 close. The identity in section 3.5 was checked against every company in that group with a P/E.
