Comparing profitability across industries

A net margin of 5% is inadequate for a software company and exceptional for a supermarket. Return on equity of 8% would embarrass a bank but might be reasonable for a utility. Profitability metrics are not universal yardsticks. They live in context. Without understanding the structural economics of an industry, you cannot assess whether a company is earning superior or inferior returns—and you risk making grave misjudgments in capital allocation.

Quick definition

Cross-industry profitability comparison means evaluating whether a company's margins (gross, operating, or net) and returns (ROE, ROA, ROIC) are strong or weak within its specific industry context. Profitability varies dramatically by industry due to differences in business models, capital intensity, competition, and pricing power. A fair comparison requires benchmarking against peers, not across industries, and understanding what drives margins in each sector.

Key takeaways

• Industry structure, not just management quality, drives profitability differences
• Software and pharmaceuticals have naturally high margins; supermarkets and utilities have naturally low margins
• Comparing a retailer's ROE to a bank's ROE is meaningless without adjusting for business model differences
• Benchmarking a company against true peers reveals competitive advantage; benchmarking across industries reveals nothing
• Capital intensity is the largest determinant of returns: asset-light businesses earn higher ROE than asset-heavy ones
• The best investment often lies in finding a company with above-average profitability for its industry

Why margins differ by industry

Profitability is fundamentally driven by three factors: the company's pricing power, its cost structure, and its capital intensity. Industry structure determines all three.

Software and high-tech businesses have high margins because once the software is built, replicating it costs almost nothing. Development costs money, but manufacturing doesn't. Gross margins are 80–95% because a customer license uses no incremental material. Operating leverage means that the 100th customer generates almost pure profit. Cloud and SaaS companies can achieve net margins of 30–50% at scale.

Specialty pharmaceuticals and biotech have high margins because patents grant monopoly pricing for years. A drug that costs $1 million to develop and manufacture might sell for $100,000 per dose. Gross margins are 70–90%. The FDA approval process creates a moat so wide that pricing power extends decades.

Supermarkets and grocery stores have thin margins (1–3% net) because competition is fierce, customer switching is costless, and products are commoditized. A customer will drive three blocks to save $0.02 per gallon on milk. Retailers compensate with extreme volume: Walmart's 2% net margin on $600 billion in revenue translates to enormous absolute profit. But the percentage is constrained by structure.

Utilities have regulated returns (typically 8–10% on equity), set by state regulators. They're capital-intensive (they must build power plants and grids), customer-concentrated (one regulator dictates all terms), and face minimal competition. The regulatory framework caps profitability to prevent monopoly pricing.

Banks have profitability constrained by leverage and regulatory capital requirements. A bank with $100 in assets, funded by $90 in deposits and $10 in equity, earns 10–15% ROE. But that same $100 in assets generates only 0.8–1.2% in net income, because the profit margin on lending is thin (the spread between deposit and lending rates). The leverage (9x) inflates ROE but the underlying business is not particularly profitable.

Insurance resembles banking: leverage amplifies returns. An insurer with $10 billion in premiums (underwriting profit of 5% = $500 million) and $100 billion in invested assets (earning 3% = $3 billion) generates $3.5 billion in net income. But that's on a base of billions in claims liabilities. The underlying profitability is modest; leverage and float magnify it.

Gross margin as an industry signal

Gross margin (revenue minus cost of goods sold, divided by revenue) is the purest measure of pricing power and production efficiency. It varies wildly by industry.

High-margin businesses (60%+): Software, pharma, cosmetics, luxury goods. These have proprietary products, brands, or patents that command premium pricing.

Medium-margin businesses (40–60%): Specialty retail, industrial equipment, restaurants. These have some differentiation or cost advantage, but face moderate competition.

Low-margin businesses (15–35%): Supermarkets, restaurants, discount retailers, basic manufacturing. These compete largely on price and scale.

When comparing a company to its peers, gross margin tells you whether the company has a cost advantage or pricing power. If Whole Foods has a 35% gross margin and Walmart has a 24% gross margin, Whole Foods isn't necessarily more profitable overall (because it has higher operating costs), but it has more pricing power and/or superior procurement.

When comparing across industries, gross margin context is critical. A pharma company with 75% gross margin appears far more profitable than a retailer with 30%, but that's expected. The meaningful question is: Does this pharma company have margins in line with its peers? Is this retailer's margin above or below the sector average?

Operating margin and leverage

Operating margin removes the effect of interest and taxes, isolating pure operations. This is where you see leverage—how fixed costs are spread over revenue.

Capital-light businesses (software, advertising, consulting) can scale revenue without proportional cost increases. Operating leverage means that once fixed costs (development, sales staff) are covered, incremental revenue drops nearly all the way to operating profit. Operating margins expand sharply as companies grow. Slack's operating margin improved from -50% to -10% as it scaled.

Capital-heavy businesses (utilities, railroads, industrial) have fixed costs in every dollar of revenue: power plants, rail lines, mines. Even as revenue grows, depreciation and maintenance scale with the base. Operating margins expand slowly and cap out. A utility might run 35% operating margin at any scale because the infrastructure is permanent and expensive.

Competitive businesses (retail, restaurants, commodity manufacturing) face margin compression as they grow because they must cut prices to capture share. A discount retailer's operating margin might fall from 6% to 4% as it enters tougher markets.

Within an industry, operating margin shows efficiency and competitive position. A retailer with 8% operating margin is superior to one with 5%, all else equal. A utility with 40% operating margin is superior to one with 35%. But a utility at 40% is not more "operationally efficient" than a software company at 50%, because the industries have different structures.

Return on equity: beware the leverage illusion

ROE (net income divided by shareholders' equity) is the most beloved return metric, but it's dangerously misleading across industries because it conflates business profitability with financial leverage.

A company with $1 billion in assets, 50% debt and 50% equity, earning 10% on assets, has ROE of 20%:

• Net profit = $1B × 10% = $100M
• Equity = $500M
• ROE = $100M / $500M = 20%

The same company with 90% debt and 10% equity earns ROE of 100% on the same 10% asset return:

• Net profit = $100M (unchanged)
• Equity = $100M
• ROE = 100%

The company hasn't become more profitable. It's just borrowed more, creating an illusion of superior returns. When (inevitably) the debt must be repaid or the business hits turbulence, the high-leverage company crashes while the low-leverage one survives.

Banks and financial companies have ROEs that look extraordinary (15–20%) compared to industrials (12–15%) or utilities (10–12%), but this partly reflects leverage embedded in their business models. A bank with 15% ROE might be less profitable in economic reality than an industrial company with 12% ROE if the bank uses 10x leverage and the industrial uses 3x.

The better comparison is return on assets (ROA), which is unaffected by leverage. A bank with 1.2% ROA is more profitable than an industrial with 1.0% ROA, regardless of leverage choices.

Return on assets and return on invested capital

Return on assets (net income divided by total assets) strips out the leverage question and reveals pure business profitability. A company that converts 2% of its asset base into annual profits is running a profitable business, regardless of financing.

Return on invested capital (NOPAT divided by invested capital) goes further: it measures how much profit the company generates from the capital it has actually invested (equity plus debt minus excess cash). This is the cleanest measure of economic profitability, but requires adjusting for one-timers and non-operating items.

Within industries, ROIC is the king metric. A retailer with 12% ROIC is creating value (if its cost of capital is 8%); one with 5% ROIC is destroying it. But comparing a software company's 45% ROIC to a utility's 8% ROIC is misleading. The utility is constrained by regulation; the software company faces no such cap. The comparison reveals nothing about who is better managed.

Capital intensity and the returns trap

Capital intensity—the ratio of assets to revenue—is the fundamental driver of ROE differences.

Asset-light businesses (software, consulting, media) can generate $1 of revenue with $0.30–0.50 of assets. These businesses require small amounts of capital to scale. They achieve high ROIC and high ROE because equity capital is small relative to profits.

Asset-heavy businesses (utilities, railroads, oil exploration) require $2–5 of assets per dollar of revenue. These businesses must build physical infrastructure. Even if they earn 10% on assets (which is solid), ROE is limited because total assets are so large relative to equity.

This is not a management quality issue. It's inherent to the industry. A utility CEO cannot achieve 30% ROE because the business model doesn't permit it. A software CEO cannot achieve 8% ROE because the business doesn't require it.

When comparing profitability, always ask: What is the capital intensity of the business? A company that earns 2% on assets in a 5:1 asset-to-revenue ratio is running a very profitable operation. One that earns 3% on assets in a 1:1 ratio is mediocre, even though the latter has higher margins.

Benchmarking within peer groups

The only meaningful profitability comparison is within a clearly defined peer group. For Walmart, peers are Target, Costco, and other discount retailers—not Amazon (different model) or Kroger (different position). For Nvidia, peers are AMD and Intel, not GE or Boeing.

Build a peer set by:

1. Identifying direct competitors (serve the same customers, offer similar products)
2. Including indirect competitors (offer substitutes, compete for the same wallet)
3. Adjusting for size and geography if relevant (a regional bank is not a peer to JPMorgan)
4. Excluding companies with radically different business models

Then calculate median gross margin, operating margin, net margin, ROIC, and ROE for the peer group. Compare your company to these medians. If your company is above the median on all metrics, it has competitive advantage. If it's below on some metrics but still earns strong returns, investigate why (lower cost structure, geographic mix, asset base).

Cyclical vs structural profitability

Some industries have structural profitability (consistent margins year to year), while others are cyclical (margins expand and contract with the cycle).

Structural profitability (pharma, software, beverages, utilities): Margins are stable across business cycles because demand is relatively constant and the company can control pricing.

Cyclical profitability (autos, cyclical industrials, commodities, homebuilding): Margins expand sharply in boom years and compress (sometimes to zero or negative) in downturns. Comparing a cyclical company's profitability at the peak of the cycle to its historical average is misleading.

When evaluating cyclical businesses, normalize profitability. Look at the through-the-cycle margin (the average over a full business cycle), not the current margin. A steel company with 15% operating margin at peak cycle is not more profitable than a utility with 35% margin; the steel company is at the top of its cycle and will face painful margin compression.

Geographic and segment differences

Large diversified companies often have profitability that varies by segment and geography. Berkshire Hathaway's insurance operations earn strong returns; its utility operations earn moderate returns. Apple's gross margin is 46%, but it varies by product line. Microsoft's profitability has improved as it shifted from software licenses to cloud services.

When comparing two diversified companies, understand the mix. If Company A earns 20% ROE and Company B earns 18% ROE, but Company A derives 60% of earnings from low-return utilities while Company B derives 60% from high-return tech, you're looking at different economic realities. Break out segment profitability and reweight to equivalent mixes before comparing.

Real-world examples

Berkshire Hathaway vs Coca-Cola: Berkshire has higher ROE (20%+) and ROIC (15%+) than Coca-Cola (ROE 35–40%, ROIC 25–30%), but Berkshire is more capital-efficient. Coca-Cola owns bottling assets and carries debt; Berkshire owns float and equities. The higher Coca-Cola multiples reflect predictable brand profitability, not superior capital efficiency. For an investor focused on returns on capital, Berkshire often offers better value.

JPMorgan Chase vs Berkshire: JPMorgan reports ROE of 15–17%, higher than Berkshire's 20%, but uses 10x leverage. Berkshire's ROA is higher (around 0.8% vs JPMorgan's 1.2%), but JPMorgan's business model (deposit-funded lending) requires leverage by design. Comparing them on ROE is misleading; comparing on ROA and ROIC after adjusting for leverage is more honest.

Adobe vs Microsoft: Adobe has higher net margins (30–35% vs Microsoft's 35–40%) but lower ROIC (25% vs 35%) because it requires more marketing spend per dollar of revenue. Microsoft's profitability is more efficient. Yet both are elite software companies. The difference reflects customer acquisition models and market maturity, not operational excellence.

Coca-Cola vs PepsiCo: Both have similar net margins (26–28%) and ROE (35–40%), but PepsiCo has lower return on assets (3.5% vs 4.2%) because it owns bottling and snack-food manufacturing, which requires more capital. Coca-Cola outsources bottling, keeping its asset base lighter. Neither is "better"—they're different business models optimized for different strategies.

Common mistakes

Comparing ROE across industries without adjusting for leverage: A bank's 18% ROE and a retailer's 12% ROE might represent identical underlying business profitability if the bank uses 2x leverage and the retailer uses 0.5x.

Using gross margin to compare across industries: A pharma company's 75% margin and a retailer's 30% margin can both be healthy; comparison is meaningless.

Ignoring cyclical peaks and troughs: Valuing a cyclical business based on peak-year profitability will overshoot; normalizing to through-the-cycle profitability is required.

Benchmarking against an arbitrary peer: Include peers that compete for the same customer dollar. Dell competing against HP is valid; Dell competing against Nvidia is not.

Confusing capital efficiency with operational efficiency: A company with low asset turnover can still be operationally efficient if it earns strong returns on those assets.

FAQ

Q: Can a low-margin business ever outperform a high-margin business? A: Yes, if it has high asset turnover and minimal capital intensity. A supermarket with 2% margin might earn 15% ROIC by turning assets over 10 times per year. A specialty retailer with 15% margin might earn 10% ROIC if it turns assets only 5 times. ROIC matters more than margin.

Q: Why do regulated utilities have lower returns than unregulated competitors? A: Because regulators cap returns to prevent monopoly pricing. A regulated utility might earn 10% on capital by law; an unregulated telecom might earn 15%. The regulation is intentional—it trades off investor returns for consumer prices.

Q: How do I benchmark a diversified conglomerate? A: Break it into segments, calculate profitability for each, compare each segment to its peer group. Then aggregate. This reveals whether the conglomerate is stronger or weaker than its parts.

Q: Is ROIC always better than ROE for comparison? A: Yes, for economic comparison. ROIC adjusts for leverage and capital structure, isolating business profitability. But ROE is what shareholders earn, so both are relevant. Calculate both and understand the difference.

Q: What profitability level indicates genuine competitive advantage? A: ROIC consistently above the cost of capital (usually 8–10%) for 5+ years. Software companies with 30%+ ROIC and pharma with 20%+ ROIC have durable advantages. Retailers with 8–10% ROIC are competitive if their cost of capital is 6–7%.

Q: Should I invest only in high-margin industries? A: No. Low-margin industries with strong competitive positions (Walmart, Costco) can be superior investments to weak high-margin competitors. Focus on companies with returns above their cost of capital, regardless of margin.

Summary

Profitability is not a universal metric. A 3% net margin is a disaster for software but a triumph for supermarkets. A 12% ROE is weak for finance but excellent for utilities. Industry structure—driven by capital intensity, competitive dynamics, and barriers to entry—determines the range of profitability that is reasonable and sustainable.

To invest wisely, benchmark each company against its true peer group and understand the structural profitability of the industry it serves. Ask: Is this company more profitable than its direct competitors? Does it earn returns above its cost of capital? If you're comparing across industries, understand what you're actually comparing. A higher margin or return often reflects industry structure, not superior management. The best investments lie in companies that outperform their peers, not in industries with high margins.
