Two different questions hide inside the phrase 'this is a profitable company'. Of every hundred rupees the business sells, how many does it get to keep? That is a margin. And of every hundred rupees of capital locked up in the business, how many does it earn back in a year? That is a return ratio. They are quoted in the same breath constantly, but they measure different things, and a company can be excellent at one while being thoroughly ordinary at the other. This topic separates the two, then walks ROA, ROE, ROCE and ROIC through a single illustrative company so you can see exactly which pool of capital each one is standing on.
What is the difference between a margin and a return ratio?
A margin is a slice of the sales line. You start at revenue, subtract a defined set of costs, and express what is left as a percentage of revenue. Every margin therefore shares the same denominator — sales — and they differ only in how many layers of cost you have removed before you stop counting.
A return ratio has nothing to do with sales. Its denominator is capital: money that was put into the business and left there. It asks a landlord's question rather than a shopkeeper's — not how much of each rupee of trade you keep, but how much the whole building earns for what it cost to buy.
That distinction explains a pattern that confuses almost everyone the first time they meet it. A jeweller or a fuel retailer can run a very thin net margin and still be a sound business, because the same rupee of capital turns over several times in a year and does several rupees of trade. A speciality chemicals plant can run a fat net margin and still earn an unremarkable return, because it took years and an enormous amount of capital to build. Margin is a statement about pricing power and cost control. Return is a statement about capital intensity. You need both readings before you can describe a business at all.
Note — Neither number carries meaning on its own. A margin is only interpretable against the same company's own history and against direct competitors selling the same kind of thing. A return ratio is only interpretable against what that capital cost to raise.
The three margins, and what actually moves each one
Almost every margin you will see quoted is one of three, taken at three different heights on the same staircase of costs. Read them together and they tell you where a change came from; read one alone and you will attribute it to the wrong cause.
Gross margin moves with input prices, product mix and pricing power — whether a rise in raw material cost can be passed to the customer or has to be absorbed. Operating margin moves with all of that plus operating leverage: fixed costs such as salaries, rent and depreciation sit still while sales rise or fall, so operating margin swings harder in both directions than gross margin does. Net margin moves with all of the above plus two things that have nothing to do with the business operating well — how much the company borrowed, and its tax position.
This is why a falling net margin alongside a steady operating margin is a completely different story from a falling operating margin. The first is usually a financing or tax event. The second is the business itself losing ground.
- Gross margin
- Revenue minus the direct cost of what was sold, divided by revenue. The rawest measure of pricing power — what the product fetches against what the material and direct manufacturing cost.
- Operating margin (EBIT margin)
- Gross profit minus the cost of running the business — salaries, selling and administration, and depreciation (the annual writing-down of the cost of plant and machines) — divided by revenue. This is the margin the business itself produces, before anything is paid to lenders or the taxman.
- Net margin (PAT margin)
- What survives after interest and tax, divided by revenue. Two companies with identical operating margins can report very different net margins purely because one borrowed more or sits in a different tax bracket.
- EBITDA margin
- Operating profit with depreciation added back, divided by revenue. Useful for comparing the cash-generating engine of two companies whose plants are of different ages, but it flatters capital-heavy businesses precisely by ignoring the cost of the plant.
Working the margins through one illustrative company
Take an illustrative mid-cap, Bharat Cables Ltd (figures illustrative, not a real company). Every rupee number on this page belongs to it, so the ratios tie back to the same set of accounts rather than floating free.
Read the right-hand column downwards and you are reading the margin at each height. Nothing here is a judgement about whether 9 per cent is good — that question cannot be answered until you know what the rest of the cable industry earns and what this company earned five years ago.
| Line item | Rs crore | As % of revenue |
|---|---|---|
| Revenue | 1,000 | 100.0% |
| Cost of goods sold | (620) | 62.0% |
| Gross profit | 380 | 38.0% — gross margin |
| Employee and other operating costs | (200) | 20.0% |
| Depreciation | (40) | 4.0% |
| EBIT (operating profit) | 140 | 14.0% — operating margin |
| Interest | (20) | 2.0% |
| Profit before tax | 120 | 12.0% |
| Tax at 25% | (30) | 3.0% |
| Net profit (PAT) | 90 | 9.0% — net margin |
ROA, ROE and ROCE — which capital base does each one measure?
This is the part almost nobody has straight, and it is the whole topic. All three ratios divide a profit figure by a pool of capital. They differ in which pool.
Return on assets uses everything the company controls, however it was paid for — factories, stock, receivables, cash, the lot. Return on equity uses only the shareholders' slice: paid-up capital plus every rupee of past profit retained in reserves. Return on capital employed uses the long-term funding of the business — shareholders' funds plus interest-bearing debt — which is the same thing as total assets minus the short-term liabilities that fund themselves, such as money owed to suppliers.
Because ROCE is measuring capital contributed by both lenders and shareholders, its numerator has to be a profit figure that has not yet been shared with either. That is why ROCE uses EBIT and not net profit. Putting PAT over capital employed compares a number that has already paid the lenders with a base that still includes the lenders' money — a mismatch that quietly understates the ratio for any company carrying debt.
ROA = Net profit / Average total assets
ROE = Net profit / Average shareholders' funds
ROCE = EBIT / Average capital employed
Capital employed = Shareholders' funds + Total debt
= Total assets - Current liabilities- Shareholders' funds = equity share capital + reserves and surplus (also called net worth or book value)
- EBIT = earnings before interest and tax, i.e. operating profit — what the business made before paying lenders or the government
- Bharat Cables: average total assets Rs 800 cr, average shareholders' funds Rs 450 cr, debt Rs 200 cr, current liabilities Rs 150 cr
The three ratios side by side, with the blind spot of each
Run the Bharat Cables numbers through and the three answers spread across a ten-point range — from 11.3 per cent to 21.5 per cent — for one company, in one year, with one set of accounts. That spread is not noise. It is the arithmetic consequence of standing on three different rungs.
| Ratio | What it measures | Denominator | Blind spot |
|---|---|---|---|
| ROA — 11.3% | How productively the total asset base is used, regardless of who funded it | Average total assets (Rs 800 cr) | Ignores funding mix entirely, and is dragged down by idle cash and revalued land sitting on the books |
| ROE — 20.0% | What the shareholders earned on the money that belongs to them | Average shareholders' funds (Rs 450 cr) | Rises purely by adding debt or by buying back shares — a smaller denominator, not a better business |
| ROCE — 21.5% | What the whole long-term funding pool earned before it was split between lenders and owners | Average capital employed (Rs 650 cr) | Cannot be flattered by leverage, but is still distorted by large surplus cash and by an old, heavily depreciated asset base |
Why ROE alone can be flattered by debt, and why ROCE cannot
Hold Bharat Cables' operations completely still — same plant, same customers, same EBIT of Rs 140 crore — and change only how the Rs 650 crore of capital employed was raised. In Structure A the company funded it with Rs 450 crore of equity and Rs 200 crore of debt. In Structure B, the same business, funded with Rs 250 crore of equity and Rs 400 crore of debt at the same 10 per cent cost.
Nothing operational has changed. Not one extra metre of cable was sold. ROE goes from 20 per cent to 30 per cent, and ROCE does not move at all.
That is the mechanism. ROE has shareholders' funds in the denominator, so replacing equity with debt shrinks the denominator faster than the extra interest shrinks the numerator — as long as the business earns more on the borrowed money than it pays for it. ROCE has both funders in the denominator and a pre-interest numerator, so the funding mix cancels out and only the operating performance shows through.
| Same business, two funding structures | Structure A | Structure B |
|---|---|---|
| Capital employed (Rs cr) | 650 | 650 |
| — of which shareholders' funds | 450 | 250 |
| — of which debt | 200 | 400 |
| EBIT (Rs cr) | 140 | 140 |
| Interest at 10% (Rs cr) | 20 | 40 |
| Profit before tax (Rs cr) | 120 | 100 |
| Tax at 25% (Rs cr) | 30 | 25 |
| Net profit (Rs cr) | 90 | 75 |
| ROE | 20.0% | 30.0% |
| ROCE | 21.5% | 21.5% |
Watch out — A ten-percentage-point jump in ROE with no change whatsoever in the underlying business is the most common way this ratio misleads. When ROE climbs while ROCE stays flat, the extra return is coming from the balance sheet rather than the factory — and leverage magnifies losses on exactly the same arithmetic when sales fall or rates rise.
ROIC — the cleanest member of the family
Return on invested capital fixes the two things ROCE still leaves loose. It taxes the numerator, so the return is stated after the government's cut and can be compared like-for-like with a cost of capital that is also stated after tax. And it removes surplus cash from the denominator, because a mountain of idle cash is not capital being invested in the operating business — it is capital waiting for a decision.
For Bharat Cables, carrying Rs 50 crore of cash it does not need for operations, ROIC works out at 17.5 per cent against a ROCE of 21.5 per cent. The gap is exactly the tax the ratio now honestly accounts for, offset a little by the smaller cash-adjusted base.
ROIC is the ratio to reach for when you want to know how good the operating business is at converting capital into profit, stripped of financing choices, tax presentation and the cash pile. It is also the number that pairs directly with cost of capital in the next block, because both are after-tax.
NOPAT = EBIT x (1 - tax rate)
Invested capital = Capital employed - Surplus cash
ROIC = NOPAT / Average invested capital
Bharat Cables:
NOPAT = 140 x (1 - 0.25) = Rs 105 cr
Invested capital = 650 - 50 = Rs 600 cr
ROIC = 105 / 600 = 17.5%- NOPAT = net operating profit after tax — what the operations earned after tax, as if the company had no debt at all
- Surplus cash = cash and liquid investments beyond what day-to-day operations need; judgement is involved, so state the assumption you used
Compare the return with the cost of capital, not with a number you memorised
There is no universal threshold at which a return ratio becomes good. The only meaningful comparison is against what that capital cost the company to raise — its weighted average cost of capital, which is simply the after-tax interest rate on its debt and the return equity holders require, weighted by how much of each is in the mix.
The logic is unforgiving and worth stating plainly. If a business earns a return on its invested capital above what that capital costs, then every additional rupee it reinvests adds value, and growth is genuinely worth having. If it earns below its cost of capital, growth destroys value — the company is putting money to work at a rate lower than the rate at which it obtained the money, and doing more of it makes the gap larger, not smaller.
This reframes the entire question. A company earning 14 per cent where capital costs 11 per cent is creating value. A company earning 18 per cent where capital costs 20 per cent — because it is small, cyclical and borrows expensively — is not, despite the higher headline. The spread matters, never the absolute level. It also explains why capital-intensive Indian sectors such as power generation and infrastructure spend long stretches with respectable-looking returns that still fall short of the cost of the money financing them.
Pro tip — When you cannot estimate a company's cost of capital with confidence, use the spread it earns over its own borrowing cost as a floor. If a business is borrowing at around 9 per cent and earning a mid-teens return on capital, the spread is real. If it is borrowing at 11 per cent and earning 12 per cent on capital, the margin for error has vanished before you have even opened the valuation question.
Why the denominator uses an average of opening and closing balances
The numerator of every return ratio is a flow — profit earned across the whole twelve months. The denominator is a stock — a balance sheet photograph taken on 31 March. Divide a full year of earning by a single day's capital and you have mismatched the two.
It matters most in exactly the situations you care about. A company that raised a large amount of fresh equity in February will show a swollen closing net worth that earned profits for barely six weeks. Divide the full year's profit by that inflated closing figure and ROE collapses for no operating reason at all. The reverse happens after a buyback: the closing base shrinks, and ROE looks like it leapt.
Averaging the opening and closing balances is the standard repair. It is crude — a mid-year fundraise is not smoothed properly by a two-point average — but it removes most of the distortion. The practical rule is simply to know which convention your data source used before comparing its number with one you calculated yourself, because screeners differ and the two answers will not match.
Average capital = (Opening balance + Closing balance) / 2
ROE = Net profit for the year
-------------------------------------------------
(Opening shareholders' funds + Closing shareholders' funds) / 2- Opening balance = the closing balance of the previous financial year, taken from the comparative column of the same balance sheet
- If a large equity raise or buyback happened mid-year, say so alongside the ratio rather than presenting the average as if it were clean
Why these ratios are meaningless across sectors
A return ratio is a statement about how much capital a business model requires. Different business models require wildly different amounts, and no amount of arithmetic makes those comparable.
An asset-light software services or consumer brand business rents its offices, owns few machines and carries most of its value in people and distribution, so its capital base is small and returns on it are structurally high. A cement plant, a steel mill or a power project has to build the asset before it earns a rupee, so the same operating skill produces a far lower ratio. Neither is better managed. They are different physical propositions, and comparing their ROCE is like comparing the fuel efficiency of a scooter and a truck.
Lenders break the frame entirely. For a bank or an NBFC, borrowing is not a financing decision sitting outside the business — it is the raw material. Deposits and borrowings are what the business buys in order to sell loans, so capital employed, debt-to-equity and ROCE as defined here simply do not carry their usual meaning. Banks are read through return on assets and return on equity against a regulated capital adequacy floor instead, which is why they get their own topic in this module.
That leaves two comparisons that do work, and only two. Compare a company against direct competitors doing substantially the same thing, and compare it against its own record over five to ten years. Everything else is noise dressed as analysis.
Example — A useful test before you compare two return ratios: could these two companies plausibly bid for the same contract or sell to the same buyer? If not, the comparison is describing two industries' capital requirements, not two management teams.
What does a consistently high return over ten years actually imply?
One year of a high return ratio says very little. A commodity producer at the top of its cycle, a company that sold a division, a business enjoying a one-off duty protection — all of them post a spectacular single year and then hand it back.
A return on capital that stays well above the cost of capital for eight or ten years, across at least one full downturn, is a different kind of evidence. In a competitive market, high returns attract entrants; entrants add capacity; capacity compresses margins; returns fall back towards the cost of capital. That is the default gravity of business. When a company defies it for a decade, something is stopping the entrants — a brand customers ask for by name, a distribution network that would take years to replicate, switching costs that make leaving painful, a regulatory licence, or a cost base structurally below everyone else's.
That is precisely what an economic moat means, and it is why the durability of a return ratio matters more than its level in any single year. A steady 18 per cent for a decade is far more informative than a 35 per cent that appeared last year. The moats topic in this module deals with where that durability comes from and how to test whether it is still intact.
Running this against a real annual report
Everything above is calculable from two pages of any annual report filed with the exchanges — the standalone or consolidated profit and loss statement, and the balance sheet with its comparative column. Use consolidated figures where the company has subsidiaries, because the standalone accounts of a holding company can show a return that the group as a whole is nowhere near earning.
Ten minutes with the accounts
- Take revenue, gross profit, EBIT and PAT from the consolidated P&L and compute all three margins for the last five years in one row each.
- Pull shareholders' funds and total assets from the balance sheet, and the previous year's figures from the comparative column, then average each.
- Compute ROE and ROCE side by side for five years. Look at whether the gap between them is widening — that is leverage entering the picture.
- Check the cash and current investments line before computing ROIC, and state how much you treated as surplus.
- Read the finance cost note for the average interest rate the company is actually paying, and compare ROCE against it.
- Look for exceptional items and other income in the P&L. A return ratio built on a one-time asset sale is not a return on the operating business.
- Repeat the whole exercise for two direct competitors before forming any view on the level.
Key points
ROCE = EBIT / Average capital employed, where capital employed = shareholders' funds + total debt = total assets - current liabilities
Example — Bharat Cables Ltd (figures illustrative, not a real company) earns EBIT of Rs 140 cr on revenue of Rs 1,000 cr — a 14% operating margin — and Rs 90 cr of net profit after Rs 20 cr interest and 25% tax, a 9% net margin. On average total assets of Rs 800 cr, average shareholders' funds of Rs 450 cr and average capital employed of Rs 650 cr, the same year produces ROA 11.3%, ROE 20.0% and ROCE 21.5%. Fund the identical business with Rs 400 cr of debt instead of Rs 200 cr and ROE rises to 30.0% while ROCE stays at 21.5% — the extra ten points came from the funding structure, not from selling more cable.
Pro tip — Chart ROE and ROCE on the same five-year view rather than reading either alone. Moving together means the operating business is doing the work. ROE pulling away from ROCE means leverage is doing it, and leverage works in both directions.
Warning — A single year's return ratio can be manufactured. A buyback shrinks the equity base, an asset sale inflates the numerator, and a fresh capital raise late in the year distorts the average. Always read at least five years, always check the exceptional items line, and always confirm whether the figure came from consolidated or standalone accounts before comparing it with anything.
Frequently asked questions
How do you calculate ROCE?
ROCE is EBIT divided by average capital employed. EBIT is operating profit — profit before interest and tax — taken straight from the profit and loss statement. Capital employed is shareholders' funds plus total debt, which is the same figure as total assets minus current liabilities. Average the opening and closing capital employed rather than using the year-end number alone.
ROE vs ROCE — which is better?
They answer different questions, so neither is universally better. ROE tells a shareholder what was earned on the money that belongs to shareholders; ROCE tells you what the operating business earned on all its long-term funding. ROCE is harder to distort because adding debt does not move it, so it is the more reliable read on business quality, while ROE is the more direct read on shareholder outcomes. Reading them together is what reveals how much of the ROE came from leverage.
What is a good ROE in the Indian market?
There is no single threshold, and any number quoted as one is being applied to sectors it does not fit. The meaningful test is whether the return sits above the company's cost of capital and whether it has stayed there across several years including a downturn. An asset-light business and a capital-heavy infrastructure business will structurally sit far apart on this measure without either being mismanaged.
Why is ROCE calculated on EBIT and not on net profit?
Because capital employed includes lenders' money as well as shareholders' money. Net profit has already had interest deducted, so putting it over a base that still contains the debt compares a post-lender profit with a pre-lender capital base. EBIT is the profit figure that has not yet been shared with either funder, which makes it the consistent numerator.
What is the difference between ROCE and ROIC?
ROIC tightens ROCE in two ways. It uses NOPAT — operating profit after tax — instead of pre-tax EBIT, and it strips surplus cash out of the capital base because idle cash is not capital invested in the operating business. That makes ROIC directly comparable with an after-tax cost of capital, which pre-tax ROCE is not.
Can a company have a high ROE and still be a weak business?
Yes, and it is common. Heavy borrowing shrinks the equity base and lifts ROE mechanically, as does a large buyback. A company with an eroded net worth from past losses can also show a startling ROE on a tiny denominator. Checking ROCE and ROIC alongside it, and looking at the debt level, is how you separate a genuinely high-return business from an arithmetically flattered one.
Why do return ratios use an average of opening and closing balances?
Profit is earned over twelve months while a balance sheet figure is a single-day snapshot. If capital changed materially during the year — a rights issue, a large buyback, a fresh term loan — dividing a full year's profit by the closing balance alone gives a distorted ratio. Averaging the opening and closing figures removes most of that mismatch, though it still cannot fully handle a large mid-year change.
