Return ratios

You look up a company on a screener and it shows a return on capital employed of 30%. You do the sum yourself from the accounts and get 16%. Neither of you has made an arithmetic mistake. You have simply divided a different profit by a different capital: the screener took a broad profit over a narrow capital base; you took operating profit over everything employed, including a large pile of idle cash. Same company, same accounts, two returns almost twice apart. illustrative

That is the trouble with return ratios. They all share one shape - a profit, divided by a capital - and that shared shape hides how much choice sits inside each one. Which profit? Operating, after-tax, net? Which capital? Equity, equity-plus-debt, total assets, or only the capital actually working? Every combination has a name - ROE, ROCE, ROIC, ROA - and every one answers a different question for a different provider of money. Get the pairing wrong, or leave the wrong things in the denominator, and you compute a number that looks authoritative and means nothing. This module is about computing each ratio so it answers the question it claims to, and about the exclusions that separate a real return from a screener's careless one.

A return ratio answers the most basic question an owner can ask: for the money tied up here, how much does the business earn? But "the money tied up here" depends on whose money you mean, and "how much it earns" must be measured before or after the claims of the people you are excluding. That is why there are four common return ratios, not one - and why they are not interchangeable. The iron rule underneath all four is that the numerator and denominator must describe the same set of capital providers.

Return on equity (ROE) is the owner's own number: net profit - what is left after lenders and the taxman are paid - over shareholders' equity, answering "what did the owners earn on their stake?" Return on capital employed (ROCE) steps back to the whole firm: operating profit (EBIT) over capital employed - equity plus debt - answering "what does the business earn on all its long-term capital, before deciding how to split that capital between owners and lenders?" Return on invested capital (ROIC) is the sharpest operating version: after-tax operating profit over the capital actually invested in operations, deliberately excluding surplus cash and non-operating investments. And return on assets (ROA) divides net profit by total assets - a blunt measure used mainly for lenders like banks, where the balance sheet is the business.

The reason to keep them straight is that pairing: ROE matches net profit (owners' profit) with equity (owners' capital); ROCE matches operating profit (everyone's profit, before interest splits it) with equity-plus-debt (everyone's capital). The classic error mixes them - dividing operating profit by equity alone, or net profit by capital employed - pairing a profit belonging to one group with a capital belonging to another, and producing a number that answers no coherent question at all. Return ratios are the single most-quoted family in all of analysis, and the most casually miscomputed: by screeners, by brokers, and by readers who never learned that the profit and the capital have to match.

Matching the profit to the capital gets you a coherent ratio. Three further disciplines get you an honest one - and then a worked cleaning makes the whole difference concrete.

Strip the denominator to what is actually working. A capital-employed figure straight off the balance sheet often carries things that are not part of the operating machine: a surplus cash pile, a portfolio of investments, a big new plant still in capital-work-in-progress (CWIP) earning nothing yet. Each swells the denominator without adding to the operating profit on top, dragging the ratio down and hiding how well the real assets are doing. To see the operating return, exclude surplus cash, non-operating investments and CWIP from the capital base - and, on the top line, exclude the non-operating income those assets throw off, so both halves describe the same operations. The gap between the raw ROCE and this cleaned-up operating ROCE is often the most interesting fact about the company.

Use average capital, not year-end. A year's profit is earned across the whole year, but a balance sheet is a snapshot on the last day. If the company raised equity or took on debt mid-year, the year-end capital is bigger than what actually earned the profit, understating the return. Average the opening and closing capital so the denominator matches the period the profit was earned over. Screeners frequently skip this - one reason their numbers drift from a careful hand calculation.

Compare the return with the cost of the capital. A return only means something against the cost of the money it used. A business earning 14% on capital that costs 11% is creating value; a business earning 14% on capital that costs 16% is destroying it, even though 14% sounds healthy. The gap between return and cost of capital - not the return alone - tells you whether the business is worth more or less for having grown. A high return still below the cost of capital is a value-destroying machine that merely looks impressive.

Now watch those exclusions do their work. A composite speciality manufacturer shows a screener ROCE of 15%, and the screen flags it as ordinary. But its balance sheet carries two things that are not part of the operating machine: a cash-and-investments pile equal to nearly a third of the capital base, built from retained profit and earning a low deposit yield, and a large new plant sitting in CWIP, not yet commissioned. Both sit in the screener's denominator. Strip them out - and the small non-operating income the cash throws off from the top line - and a different company appears. illustrative

Work it through. The screener divided ₹130 crore of operating profit by ₹870 crore of capital employed - 15%, unremarkable. But ₹410 crore of that capital is not operating: ₹290 crore is surplus cash and investments earning a low yield, and ₹120 crore is a plant still in CWIP, earning nothing. Strip those out and operating capital is ₹460 crore. Remove the ₹12 crore of non-operating income the cash throws off, leaving ₹118 crore of genuinely operating profit. The operating return is ₹118 ÷ ₹460 ≈ 26%, not 15%. And against a cost of capital of about 12%, a 26% operating return is creating real value on every rupee - while the CWIP currently dragging the reported number down is about to add more of that high-returning capacity once it commissions. The screener's 15% hid a strong business behind a fat cash balance and a plant that has not switched on. The habit to build is to never trust a screener's return ratio until you have taken its denominator apart.

Return ratios are the family that breaks most dramatically across sectors - some are the wrong tool entirely, some produce huge numbers that mean far less than they seem. A return ratio assumes a clean split between operating capital and financing, and that assumption is exactly what some businesses do not honour.

For a lender, borrowing is not financing but stock-in-trade, so ROCE has no clean base and ROA/ROE take over. For an asset-light firm, the denominator is so small that a 35–40% ROE is arithmetic on a near-zero equity base, not proof of a superhuman business - judge it on margins, growth and cash conversion. For a holding company, consolidation double-counts subsidiaries, so a group return ratio is not measuring one coherent thing at all. Only the manufacturer honours the ratio's assumptions cleanly, and even there the raw number needs the exclusions above before it tells the truth. So a return ratio is a question about capital productivity, and you must first ask whether this business has the kind of capital the ratio is built to measure.

A return ratio tells you how well capital is being used, but not how much of it the business can reinvest at that rate - and for a long-term owner the second question often matters more. A company earning 40% but able to redeploy only a trickle of new capital compounds slowly; a company earning 18% but able to pour large sums back at that same 18% compounds far faster. Return times reinvestment is what builds value, and the ratio is only the first half of that product. A superb return the business cannot reinvest is not wasted - it becomes cash the owner can take out - but it will not compound inside the company, and a return with no runway is a good business, not automatically a great investment.

Nor does the ratio tell you whether the return will last. A high ROIC attracts competition, and competition is the force that pulls returns back toward the cost of capital. Whether a high return persists depends on the moat around it - a brand, a cost advantage, a network, a regulatory barrier - and none of that is inside the ratio. A high return with no moat is a magnet for the very competition that will erode it.

And a return ratio inherits every distortion in the two numbers that build it. If the operating profit is flattered by an accounting choice, or the capital underneath has been shrunk by write-offs or kept off the balance sheet through leases, the ratio computes cleanly and misleads completely. A return that looks high because the denominator was quietly hollowed out is the subject of a later module on how ratios get gamed. The ratio cannot tell you whether its own inputs were honest; that check is yours to make.

When management leads with a headline return, a sharp analyst refuses it until the denominator is clean: "You've quoted a 22% ROCE. Is that on average capital or year-end, and does the denominator include the cash pile and the CWIP? What's the return on operating assets alone, and where does it sit against your cost of capital?"

A good answer, verbatim-style.

"Good question. The 22% is on average capital employed including everything. If you strip out the surplus cash and the plant under construction, the return on operating capital is around 31%, well above our cost of capital of about 12%. The CWIP will lift reported ROCE as it commissions and ramps. So the operating business earns in the low thirties; the headline is diluted by cash and the build."

That names the basis, gives the cleaned-up operating return, and sets it against the cost of capital - everything you need to judge whether value is being created.

An evasive answer, verbatim-style.

"We're very proud of our best-in-class 22% ROCE, which reflects our capital discipline and operational excellence. We're confident of maintaining industry-leading returns as we continue to invest for growth."

Notice what is missing: the basis, what is in the denominator, and any mention of the cost of capital. "Best-in-class" and "capital discipline" are adjectives standing in for the decomposition that would let you check the number. If the room lets "22%, best-in-class" stand without the operating figure, either the operating return is lower than the headline (because non-operating income is flattering the top line) or management does not compute it that way and is quoting the screener's number back at you. A return the company will not clean up is a return worth cleaning up yourself.
