Gross Margin vs Operating Margin Explained

Two apparel brands sold their FY2025 the same way at the factory door. Lululemon and PVH Corp — the owner of Calvin Klein and Tommy Hilfiger — both kept almost exactly the same slice of every revenue dollar after the cost of making the clothes: a 59.2% gross margin for Lululemon, 59.4% for PVH (Inve data, FY2025; both fiscal years ended the same day, 2 Feb 2025). On the cost of the product, they are twins. Then you read one line lower. Lululemon turned that into a 23.7% operating margin; PVH kept 8.9% (Inve data, FY2025). Same gross margin, less than half the operating profit. The difference is not in the factory. It is in everything that happens after the factory.

These two companies are used purely to illustrate how the margins behave — this is not a view on either stock.

That gap is the single most informative thing the income statement will tell you about whether a business has real operating leverage or just a nice-sounding top-of-funnel number. Most retail analysis stops at gross margin or jumps straight to net profit. The relationship between the two margins is where the actual story sits — and it is the story management discusses every quarter on the concall, sometimes honestly. Across 15,726 commitments tracked on Inve over 1,547 listed Indian companies, barely half are delivered as stated (Inve data, as of 2026-06-12), and margin-expansion guidance is among the classes most likely to quietly go silent. This piece is about reading the two margins together, so you can tell pricing power from cost discipline — and spot when neither is really there.

What is the difference between gross margin and operating margin?

The two margins sit at different points on the income statement and answer different questions.

Gross margin measures what is left of each rupee of sales after the direct cost of producing the goods — raw materials, manufacturing labour, freight in. It is a read on pricing power and input costs.

One caveat before we go further, and it is the reason the worked example below uses two US-listed brands rather than Indian ones. For most Indian listed companies a clean gross margin is hard to compute reliably, because only raw-material cost is separately disclosed — other direct costs sit buried inside "other expenses." That is why analysts here often lean on EBITDA or operating (EBIT) margin as the more dependable read on profitability, and treat any reported "gross margin" for Indian names with care. US filers, by contrast, disclose cost of goods sold as a line, so the gross-to-operating walk is clean and comparable — which is exactly what we need to see the mechanism plainly before applying it one rung lower to Indian names.

Operating margin measures what is left after both direct costs and the costs of running the business — employee salaries, marketing, distribution, administration, rent (collectively SG&A), plus depreciation and amortisation. It is a read on the whole operating engine.

Gross margin asks: can this company sell its product for meaningfully more than it costs to make? Operating margin asks: after paying for everyone and everything needed to actually run the company, how much survives? The first is about the product. The second is about the business. A company can win the first and lose the second — and many do.

A real example: same gross margin, very different businesses

Here are the two brands from the opening, line by line, for the financial year ended February 2025.

Source: Inve data, FY2025 (both fiscal years ended 2 Feb 2025). Illustration of the mechanism, not a view on either stock.

On the factory floor these two are indistinguishable: a 59.2% gross margin against a 59.4% one. The clothes carry near-identical product economics. Below the gross-profit line they part ways completely, and the whole of the difference has one name — SG&A. Lululemon spends 35.5 cents of every revenue dollar on running the business; PVH spends 51.0 cents. That single 15-point gap in overhead is almost exactly the gap in operating margin. The product advantage is the same; one company keeps it, the other hands it back to its own cost base.

Put the two operating margins far apart and let the arithmetic land: 23.7% against 8.9%. An owner of the first business keeps nearly a quarter of every sales dollar as operating profit before tax and interest; an owner of the second keeps under a tenth. An investor who screened only on gross margin would have dropped these two in the same bucket and moved on. The investor who read both lines would not have come close to treating them as alike.

Where does operating leverage actually show up?

Operating leverage is the thing growth investors are really paying for, and it lives precisely in the space between gross and operating margin.

Here is the mechanism. Cost of goods sold is mostly variable — make twice as many units and you spend roughly twice as much on materials, so gross margin tends to stay fairly flat as revenue grows. SG&A is largely fixed — the head office, the IT systems, much of the brand spend do not double when revenue doubles. So as a company scales, revenue can rise faster than SG&A, and a larger slice of each incremental rupee of gross profit drops through to operating profit.

Lululemon's own history shows the signature. In the year ended January 2017, revenue was USD 2.34 billion, gross margin 51.2%, operating margin 18.0% (Inve data, FY2017). Eight years later revenue was USD 10.59 billion — roughly four and a half times larger — gross margin had climbed to 59.2%, and operating margin to 23.7% (Inve data, FY2025). The business got both a better product economic and a more efficient cost base as it scaled: the gross margin rose about 8 points, but operating margin rose nearly 6 points on top of an SG&A line that, as a share of revenue, barely moved (33.2% to 35.5%). That is operating leverage doing its quiet work — the most valuable pattern in the whole income statement.

The opposite signature is the warning. When gross margin holds or even improves but operating margin stays flat or shrinks, the company is spending away its product advantage on overheads. PVH in FY2025 is that case frozen in a single year: a 59.4% gross margin, full pricing power on the clothes, almost entirely consumed by a 51.0% SG&A line. The product is fine; the business is leaking. That divergence is invisible if you look at gross margin alone, and it is one of the cleanest early signals that scale is not translating into profitability.

How do you read the two margins together over time?

A single year of margins is a snapshot; the relationship across years is the signal. Four patterns are worth naming.

Gross steady (or rising), operating expanding. The premium pattern — operating leverage is real and the business gets more profitable as it scales. Lululemon FY2017 to FY2025 is the textbook version.

Gross expanding, operating flat or shrinking. A red flag dressed as good news. The company is gaining pricing power or cutting input costs but giving it all back below the line — usually rising marketing intensity or overhead creep. Ask the concall: where is the SG&A growth going, and is it building something durable or just defending share?

Gross shrinking, operating holding. Input-cost pressure or price competition is squeezing the product, and management is protecting operating margin by cutting overheads. Sustainable for a while, but cost-cutting has a floor; eventually the gross-margin problem has to be addressed at source.

Both shrinking. Pricing power and cost discipline are failing together. No clever framing fixes this.

The discipline is simple: never read one margin without the other. Gross margin alone flatters; operating margin alone hides whether the problem is the product or the overheads. The two together tell you which lever is moving — and which lever management can actually pull.

Where we could be wrong: the leverage can run backwards

It would be neat to leave Lululemon as the hero and PVH as the cautionary tale. The data won't allow it, and that is the more useful lesson.

In the very next year — the one ended February 2026 — Lululemon's gross margin slipped from 59.2% to 56.6%, SG&A as a share of revenue rose from 35.5% to 36.6%, and operating margin fell from 23.7% to 19.9% (Inve data, FY2026). All three patterns above ran in reverse at once: the product gave back margin and overheads grew as a share of a slower-growing top line. Operating leverage is not a ratchet. The same fixed-cost base that flatters a fast-growing business punishes it the moment growth stalls, because the costs do not shrink as quickly as revenue does. A single great year of expanding operating margin can be operating leverage — or it can be a cyclical peak you are about to extrapolate off a cliff. The honest reading is that the direction and durability of the gap matters more than any one year's level, and a clean upward run can turn without warning. Read at least five to seven years, and treat the latest expansion as a hypothesis, not a law.

Where management guidance meets the margin gap

This is where the concall earns its keep, and where an Indian name brings the lesson home. Management talks about margins every quarter, and the way they talk reveals which lever they are relying on — and whether they keep facing the number once it stops cooperating.

Take GMM Pfaudler, the chemical-equipment maker. On its Q4 FY25 call (May 2025), managing director Tarak Patel was direct about the domestic business: "India margins will continue in this range as well 15%-16% should be achievable for next financial year" (GMM Pfaudler Q4 FY25 concall). On the next call, Q1 FY26, the company reaffirmed it: "So, as per our the current estimate, 15%-16% is sustainable" (GMM Pfaudler Q1 FY26 concall, as parsed by Concall AI). On the Q2 FY26 call the India standalone EBITDA-margin target was not addressed, and it was not addressed again on the Q3 FY26 call either — guided twice, then dropped from the conversation across the two calls that followed. Inve's Promise Tracker logs that last step as ghosted (Inve data, Q3 FY26). Meanwhile the consolidated business was running at an 11.9% EBITDA margin for FY25 (GMM Pfaudler Q4 FY25 concall) — well below the 15-16% the India unit was pointed at.

This is an illustration of how to read a guidance trail, not a view on GMM Pfaudler stock.

Watch the direction of the words against the direction of the delivery. On the consolidated business the company actually revised its margin aspiration up — from a 15% "margin profile across the businesses" to a stated medium-term goal of returning to "the 16% to 18% range" — while the realised number sat around 11.4% (Inve data, Q3 FY26). Guidance moving up while delivery stays flat is its own kind of tell. A margin screen will show you the number went sideways; it will not tell you management once guided that it wouldn't, then stopped repeating the figure when it didn't move. That is the difference between watching a ratio and watching a management.

Inve's Promise Tracker records these forward commitments across 1,500-plus listed companies, with the original quote and a current verdict, so a target that was guided and then quietly walked away from shows up as ghosted rather than vanishing. Across the corpus, 47% of companies have at least one commitment that went silent this way (Inve data, as of 2026-06-12). Read together, the margin trend and the delivery record become far more selective than either alone: the gross-to-operating gap shows whether the leverage is materialising, and the commitment record shows whether management keeps facing the number. The same logic underlies our piece on what EBITDA margin quietly hides — the line you lead with is rarely the line that decides the outcome.

How to use gross and operating margin in screening

A repeatable workflow:

1. Pull both margins for five to seven years. The trend matters more than any single year — and, as Lululemon's FY2026 reversal shows, more than the latest one. Plot them on the same axis so the gap is visible.
2. Watch the gap, not just the levels. A widening gap (gross rising faster than operating) signals overhead creep; a narrowing gap (operating catching up to gross) signals operating leverage at work.
3. Sector-adjust. Software and consumer brands carry high gross margins and live or die on SG&A discipline — the Lululemon-versus-PVH gap is entirely an SG&A story. Manufacturers carry thinner gross margins where small moves matter more. Compare within the sector. The same gap-reading discipline applies to returns — see what the ROCE vs ROE gap reveals for the capital-efficiency version of the same idea.
4. Decompose the SG&A. If operating margin is lagging, find out whether the culprit is employee costs, marketing, or distribution — the concall and annual report usually break it out.
5. Cross-check the guidance. If management has guided to margin expansion, check whether they keep reporting against it. The KPI Screener lets you compare operating margins across peers with trend and confidence flags, so you can see whether a company's leverage story holds up against its sector.

Frequently asked questions

Gross margin is the headline; operating margin is the verdict. A business can manufacture a great-looking gross margin and still fail to turn it into anything an owner can keep — PVH and Lululemon started FY2025 from the same 59% and ended it 15 points apart on what reached operating profit, all of it decided in the salaries, marketing and overheads between the two lines. Read the two margins as a pair, watch the gap across years, accept that even a clean run can reverse, and check whether management keeps facing the number or lets it slip off the deck. What must a five-year owner believe for the gap to keep narrowing — that the product holds its price and that the cost base stays disciplined as the company grows? If you can only get comfortable with one of those, you are only halfway to an answer.
