Calculate gross margin, sales margin, and net profit margin for your business or product. Understand what you're keeping from every sale.
Gross Margin
Profit margin is the percentage of revenue that becomes profit after deducting costs. It is the most fundamental measure of business financial health — it tells you how efficiently a company converts sales into profit and whether the underlying business model is viable. The higher the margin, the more of each revenue dollar the business retains after covering the cost of earning that dollar.
There are three primary margin types that correspond to three layers of the income statement. Gross margin strips out only the direct cost of producing goods or delivering services, revealing production efficiency. Operating margin deducts all operating expenses including overhead, revealing operational efficiency. Net margin deducts everything — including interest and taxes — revealing the ultimate bottom-line profitability of the entire enterprise.
The margin calculation has been foundational to business analysis for centuries. Early merchants tracked the spread between their purchase price and selling price — the original gross margin — as the primary indicator of whether a trade was profitable. Modern accounting codified this into the income statement structure we use today, separating costs into production versus overhead to reveal the two distinct layers where profitability can be gained or lost.
Professional financial analysts use margin analysis as a core component of equity research, competitive analysis, and due diligence. When assessing a public company, analysts track gross margin trends over multiple years — expansion signals pricing power or cost efficiency; compression signals competitive pressure or cost inflation. Operating margin reveals management's ability to control overhead as the business scales. Net margin, while the most visible, is least useful for operational comparison because it reflects capital structure and tax decisions as much as underlying business performance.
For business owners, margin analysis is the diagnostic tool that separates revenue growth from profitability growth. A business can double its revenue while its profit margin halves — generating the same absolute profit despite twice the sales volume. Only by tracking margins separately from revenue can owners identify whether growth is creating leverage (margins expanding as scale increases) or simply spreading losses (margins flat or declining as costs grow with revenue). Our profit margin calculator makes this analysis instant and actionable for businesses of any size.
Enter your revenue and cost data and the calculator simultaneously computes gross margin, operating margin, and net margin — giving you a complete profitability picture across the full income statement in seconds.
Gross Margin
The percentage of revenue remaining after subtracting the cost of goods sold (COGS). Gross margin measures production or service delivery efficiency. A high gross margin means the business has significant revenue remaining after direct production costs to fund overhead and generate profit.
Operating Margin (EBIT Margin)
The percentage of revenue remaining after subtracting both COGS and operating expenses. Operating margin measures the efficiency of core business operations before financing costs and taxes. It is the primary comparison metric for evaluating management performance across companies with different capital structures.
Net Profit Margin
The percentage of revenue remaining as net income after all expenses: COGS, operating expenses, interest, and taxes. Net margin is the most comprehensive profitability measure. It reflects the overall efficiency of the business model, including financing decisions and tax management.
EBITDA Margin
Earnings Before Interest, Taxes, Depreciation, and Amortization as a percentage of revenue. EBITDA margin approximates operational cash generation and is widely used in business valuation because it strips out non-cash and non-operational charges, enabling comparison across companies with different depreciation schedules and debt levels.
Revenue: Total sales for the period. Include all revenue streams from all products and services.
Cost of Goods Sold (COGS): Direct costs of producing your product or delivering your service: materials, direct labor, and direct overhead. Exclude selling, marketing, and administrative expenses.
Operating Expenses: Indirect costs of running the business: salaries not in COGS, rent, utilities, marketing, software, and G&A. Input this separately from COGS to see operating margin.
Interest and Taxes: Financing costs (interest on loans) and income tax expense. Used to compute net margin from operating profit.
Gross Profit & Gross Margin %: Revenue minus COGS, expressed in dollars and as a percentage of revenue.
Operating Profit & Operating Margin %: Gross profit minus operating expenses, showing core business profitability.
Net Income & Net Margin %: Operating profit minus interest and taxes — the final bottom-line result.
Margin Waterfall: A visual breakdown showing how each cost layer reduces the percentage of revenue remaining as you move from gross to operating to net margin.
Four formulas cover the complete range of profit margin types used in business analysis. Each formula uses a different cost baseline, revealing profitability at a specific stage of the income statement.
Revenue: $2,000,000 | COGS: $400,000 | Operating Expenses: $1,100,000 | Interest + Taxes: $80,000
Gross Margin: ($2M - $400K) / $2M = $1,600,000 / $2,000,000 = 80%
Operating Margin: ($1,600,000 - $1,100,000) / $2,000,000 = $500,000 / $2,000,000 = 25%
Net Margin: ($500,000 - $80,000) / $2,000,000 = $420,000 / $2,000,000 = 21%
Interpretation: 80% gross margin is excellent for SaaS. Operating expenses consume 55% of revenue (S&M: 40%, G&A: 15%), leaving 25% operating margin. Net margin of 21% after modest interest and taxes. This business is generating strong profits while investing heavily in growth — a classic high-quality SaaS profile.
Monthly Revenue: $120,000 | Food & Beverage COGS: $40,000 | Labor + Rent + Overhead: $68,000 | Taxes: $3,600
Gross Margin: ($120K - $40K) / $120K = $80,000 / $120,000 = 66.7%
Operating Margin: ($80K - $68K) / $120K = $12,000 / $120,000 = 10%
Net Margin: ($12K - $3.6K) / $120K = $8,400 / $120,000 = 7%
Interpretation: 66.7% gross margin is strong for a restaurant (food cost ratio 33% is within target range). Labor and rent consuming 56.7% of revenue is above industry ideal of 50-55% combined. 7% net margin is acceptable but leaves little buffer. The key improvement lever is labor cost optimization during slow periods.
Profit margin is the most revealing single number in business analysis because it captures the efficiency of the entire business model in one figure. Revenue tells you how large a business is. Profit margin tells you how good it is. A $10M revenue business with 20% net margin generates the same profit as a $20M revenue business with 10% net margin — but the higher-margin business achieved it with half the sales volume, indicating a fundamentally superior competitive position.
For business owners, tracking margins over time reveals whether the business model is scaling correctly. If revenue doubles but margin stays flat, the business lacks operating leverage — costs are growing proportionally with revenue. If revenue doubles and margin expands, fixed costs are being leveraged across a larger revenue base — the hallmark of a scalable business model. The savings goal in every high-quality business is margin expansion over time.
Investors use margin analysis to assess competitive moats. Companies with consistently above-industry margins possess one or more of: pricing power (customers will pay more for their offering), cost advantages (lower production costs than competitors), or scale advantages (fixed costs spread over larger revenue bases). Eroding margins signal that competitive advantages are weakening — a major red flag for long-term value creation.
A common misunderstanding: high gross margin alone does not guarantee a profitable business. Many high-gross-margin businesses destroy value because operating expenses — particularly sales, marketing, and R&D — consume the gross profit and more. The path from high gross margin to genuine profitability requires operating leverage: the ability to grow revenue without proportionally growing operating expenses. Understanding the margin waterfall from gross to operating to net reveals exactly where value is being created and where it is being consumed.
Finally, margins are essential for pricing decisions. Without knowing your gross margin, you cannot determine whether a discount is profitable, whether a new customer segment is worth pursuing, or whether a product line should be expanded or discontinued. Every pricing decision implicitly assumes a margin outcome — the profit margin calculator makes that assumption explicit and calculable, replacing intuition with arithmetic.
A B2B SaaS company with $5M ARR: Revenue $5M, COGS (hosting + support) $750K = 85% gross margin. Sales & Marketing $2M (40%), R&D $1M (20%), G&A $500K (10%) = $3.5M operating expenses. Operating profit: $750K = 15% operating margin. This is a typical growth-stage SaaS profile: exceptional gross margin, significant reinvestment in growth, modest but improving operating margin. At $20M ARR with the same fixed overhead, operating margin would expand to approximately 40%.
A 3-location restaurant group with $3.6M annual revenue: Food & beverage COGS $1.26M = 65% gross margin. Labor $1.26M (35%), rent $360K (10%), other overhead $432K (12%) = $2.052M operating expenses. Operating profit: $288K = 8% operating margin. Net profit after taxes: $196K = 5.5% net margin. Industry-standard 65% gross margin, but combined labor + rent at 45% of revenue is above the 35-40% target, compressing net margin. The primary improvement opportunity: labor scheduling optimization to reduce overtime and slow-period staffing.
A DTC skincare brand with $8M revenue: Product COGS $2.4M = 70% gross margin. Fulfillment $1.2M (15%), paid acquisition $2.4M (30%), other overhead $800K (10%) = $4.4M operating expenses. Operating loss: $800K = -10% operating margin. Despite 70% product gross margin, fulfillment and paid acquisition consume 45% of revenue, producing a loss. The path to profitability: improve customer lifetime value through repeat purchases (reducing effective CAC per revenue dollar) and shift toward organic/owned channels. At 3× repeat purchase rate, effective CAC falls from 30% to 10% of revenue, turning -10% operating margin to +20%.
Confusing margin with markup
A 40% markup produces a 28.6% margin, not a 40% margin. Applying markup percentage where margin percentage is needed leads to systematic underpricing. Always verify price by back-calculating margin from the result: (Price - Cost) / Price. If your target is 40% margin, apply a 66.7% markup, not a 40% markup.
Misclassifying costs between COGS and operating expenses
Including fixed overhead in COGS overstates the marginal cost of producing one more unit and understates gross margin. COGS should include only variable production costs — materials, direct labor, and direct production overhead. Facilities rent, management salaries, and marketing belong in operating expenses. Misclassification distorts the cost analysis that drives product and pricing decisions.
Discounting without calculating break-even volume
A 10% discount on a 40% gross margin product requires a 33% volume increase to maintain the same gross profit dollars. Most businesses authorize discounts without doing this calculation and accept volume increases far below the required level, generating less total gross profit than before the discount. Always calculate the required incremental volume before authorizing any discount.
Comparing margins across different industries
A 5% net margin is excellent for a grocery retailer but a warning sign for a software company. Industry structure, competitive dynamics, capital intensity, and revenue model all determine achievable margins. Compare your margins only to companies in the same industry, at similar scale, with similar business models. Cross-industry margin comparisons generate meaningless conclusions.
Treating gross margin as the sole profitability measure
Many business owners focus exclusively on gross margin while their operating expenses erode the gross profit and drive the business toward loss. Gross margin is necessary but not sufficient for profitability. Track operating and net margin with equal discipline — they reveal whether overhead is appropriate for the revenue base and whether the overall business model is viable.
Ignoring product and customer mix effects on blended margin
Blended margin = weighted average margin across all products and customers. Revenue growth that comes disproportionately from lower-margin products or customers compresses blended margins even when individual product margins are unchanged. A business growing revenue 20% but seeing blended margin fall 5 percentage points has a mix problem, not a pricing problem. The fix is to prioritize high-margin revenue, not reduce low-margin product cost.
Analyzing margin on a single period without trend context
A single period gross margin tells you the current state; a margin trend over 4–8 quarters tells you the direction of competitive position. Expanding margins signal pricing power, scale leverage, or efficiency improvement. Contracting margins signal competitive pressure, cost inflation, or scale diseconomy. Always plot margin over time, not just at a point in time.
Use these benchmarks to assess where your business margins stand relative to industry peers. Significant deviation below these benchmarks warrants investigation; significant deviation above suggests competitive advantage worth protecting.
| Industry | Gross Margin | Operating Margin | Net Margin |
|---|---|---|---|
| Software / SaaS | 70–85% | 15–30% | 12–25% |
| Financial Services | 50–70% | 25–40% | 18–30% |
| Healthcare Services | 40–60% | 10–20% | 8–15% |
| Manufacturing | 25–40% | 8–15% | 5–10% |
| Restaurant / Food Service | 60–70% | 5–12% | 3–9% |
| Retail (non-grocery) | 25–50% | 4–10% | 2–6% |
| E-Commerce / DTC | 20–45% | 2–8% | 1–5% |
| Grocery / Supermarket | 25–30% | 2–5% | 1–3% |
Benchmarks represent typical ranges for established businesses. Early-stage and high-growth companies may deviate significantly. Data sourced from public company filings and industry financial surveys. Updated June 2026.
Contribution margin separates variable costs from fixed costs, enabling break-even analysis and make-vs-buy decisions that gross margin alone cannot support. Contribution margin = (Revenue - Variable Costs) / Revenue. Break-even revenue = Fixed Costs / Contribution Margin Ratio. A business with $200,000 monthly fixed costs and 50% contribution margin breaks even at $400,000 monthly revenue. Every dollar of revenue above $400,000 generates 50 cents of profit. Understanding this structure allows managers to model the profit impact of volume changes at any point on the revenue curve.
Blended company margins mask the true economics of individual products, customer segments, and distribution channels. A company with 40% blended gross margin may have one product line at 70% and another at 15%. Segment-level margin analysis reveals which products are subsidizing which, enabling better resource allocation and strategic pricing decisions. At minimum, separate margins by: product category (which products drive profitability), customer type (which customer segments are most profitable), and channel (which distribution channels deliver the best margin after channel costs). This analysis frequently reveals that 20-30% of revenue generates 80%+ of gross profit.
A systematic margin expansion roadmap prioritizes improvements by impact and feasibility. Highest-leverage levers: (1) price increases — a 5% price increase with 0% volume loss delivers pure margin; (2) product mix optimization — shift revenue toward highest-margin offerings through sales incentives and packaging; (3) operational efficiency — reduce direct labor through automation or process improvement. Medium-leverage levers: (4) supplier renegotiation — use volume and multi-year contract commitments to improve COGS; (5) overhead rationalization — audit and reduce discretionary operating expenses; (6) churn reduction in subscription businesses — retained customers have 100% gross margin on incremental periods.
Profit margins are directly embedded in business valuations. In discounted cash flow (DCF) analysis, higher operating margins produce higher free cash flow, which compounds into dramatically higher intrinsic values. In comparable company analysis (comps), high-margin businesses receive premium revenue multiples because each dollar of revenue is worth more in profit terms. In EBITDA-multiple valuations, every 1 percentage point of EBITDA margin improvement multiplied by a 10× EBITDA multiple adds $10 of enterprise value per $100 of revenue. A $5M revenue business improving EBITDA margin from 15% to 20% adds $250,000 × 10× = $2.5M of enterprise value — entirely from margin improvement with no revenue growth.
Work through this checklist quarterly to systematically identify and capture margin improvement opportunities across all three layers of your income statement.
Calculate margin at all three levels
Run gross, operating, and net margin calculations for the current period and compare to prior periods. Identify at which layer the most compression or expansion is occurring.
Benchmark against industry peers
Compare gross, operating, and net margins to public company filings or industry databases in your sector. Identify whether gaps are in COGS efficiency or overhead structure.
Analyze margin by product and customer segment
Separate margin by product line and customer type. Identify your highest and lowest margin segments. Assess whether resources are allocated toward the most margin-generative activities.
Test a price increase scenario
Model the margin impact of a 5% price increase on your top 3 products with 0%, 5%, and 10% volume loss. In most businesses, a 5% price increase with less than 10% volume loss is margin-positive.
Audit top 5 COGS components
Identify the five largest COGS line items. For each, assess: Has the price been renegotiated in the last 12 months? Is the quantity optimized? Is there an alternative supplier or material? Even a 5% reduction in one large COGS item materially improves gross margin.
Review operating expense efficiency ratios
Calculate key expense ratios as % of revenue: S&M, R&D, G&A. Compare to industry benchmarks. If any ratio is materially above benchmark, investigate root causes and set a 90-day reduction target.
Calculate contribution margin and break-even
Separate variable from fixed costs. Calculate contribution margin and break-even revenue. This reveals whether the business model is fundamentally viable and how sensitive profits are to revenue changes.
Set specific margin targets for the next quarter
Based on the analysis above, set a specific gross margin improvement target (e.g., +1 percentage point in 90 days) and identify the 2-3 specific actions that will achieve it. Vague margin improvement goals produce no improvement.

Profit margin is the percentage of revenue that remains as profit after deducting costs. The three primary types are: gross margin (revenue minus COGS, divided by revenue), operating margin (revenue minus COGS and operating expenses, divided by revenue), and net margin (net income divided by revenue). Each measures profitability at a different stage of the income statement, with net margin being the most comprehensive overall measure.
Good profit margins vary significantly by industry. Software/SaaS: gross margin 70-85%, net margin 15-30%. Restaurants: gross margin 60-70%, net margin 3-9%. Retail: gross margin 25-50%, net margin 2-6%. Manufacturing: gross margin 25-40%, net margin 5-10%. E-commerce: gross margin 20-40%, net margin 1-5%. Compare your margin to industry peers, not absolute standards.
Margin = (Price - Cost) / Price. Markup = (Price - Cost) / Cost. A product costing $60 and selling for $100 has a 40% margin but a 66.7% markup. Confusing the two leads to chronic underpricing — if you need a 40% margin, you must apply a 66.7% markup, not a 40% markup.
Gross profit margin = (Revenue - Cost of Goods Sold) / Revenue × 100. Example: $500,000 revenue, $300,000 COGS. Gross profit = $200,000. Gross margin = 40%. COGS includes only direct production costs. Operating expenses are excluded from the gross margin calculation.
Operating margin = (Revenue - COGS - Operating Expenses) / Revenue × 100. It includes all costs of running the business except interest and taxes. Operating margin is the primary metric for comparing operational performance across companies with different financing structures and tax situations.
Net profit margin = Net Income / Revenue × 100. Net income is what remains after all expenses: COGS, operating expenses, interest on debt, and income taxes. It is the most comprehensive measure of overall profitability and the bottom-line efficiency of the business model.
Improve margins through four levers: (1) Increase prices — a 5% price increase with no volume loss delivers greater margin impact than a 5% cost reduction; (2) Reduce COGS — negotiate suppliers, improve production efficiency; (3) Reduce operating expenses — scrutinize overhead; (4) Improve sales mix — prioritize higher-margin products and customers.
Contribution margin = (Revenue - Variable Costs) / Revenue. It measures how much each sale contributes to covering fixed costs before generating profit. A product with negative contribution margin destroys value with every sale. Contribution margin is the foundation of break-even analysis and product mix decisions.
Pricing is the single most powerful margin lever. A 1% price increase (with constant volume) flows entirely to profit. A 1% cost reduction improves profit by less because you still pay the remaining 99% of costs. Value-based pricing consistently delivers higher margins than cost-plus pricing.
EBITDA margin = EBITDA / Revenue. It removes non-cash charges (depreciation and amortization) and financing costs (interest) to compare operational cash generation across companies with different capital structures. In M&A, enterprise value is often expressed as a multiple of EBITDA.
Enter your revenue, COGS, and operating expenses. The calculator computes gross, operating, and net margin simultaneously. Separating costs into COGS vs. operating expenses reveals where profitability is gained and lost across the income statement.
Operating leverage measures how revenue changes affect operating profit, driven by the ratio of fixed to variable costs. High fixed cost businesses (SaaS, manufacturing) see amplified margin expansion in revenue growth — a 10% revenue increase may produce 30-40% more operating income. Fixed costs do not scale with revenue.
Margin expansion occurs when profit margin percentage increases over time. It happens through revenue growth outpacing cost growth, price increases, operational efficiency, or product mix shifts toward higher-margin offerings. Investors prize margin expansion companies as evidence of increasing business quality.
Break-even revenue = Fixed Costs / Contribution Margin Ratio. Higher contribution margin means fewer sales needed to cover fixed costs. A business with $100,000 monthly fixed costs and 40% contribution margin breaks even at $250,000 monthly revenue. The same business at 25% contribution margin breaks even at $400,000.
Industry structure fundamentally determines achievable margins. Software: 70-80% gross margins due to near-zero marginal delivery cost. Grocery: 1-3% net margins due to commodity competition. Healthcare services: 8-15% net margins. Luxury goods: 60-70% gross margins from brand value. Never compare margins across unrelated industries.
SaaS gross margin = (SaaS Revenue - Cost of Revenue) / SaaS Revenue. Best-in-class SaaS gross margins are 75-85%. Below 65% indicates architecture inefficiency or high support costs. Gross margin determines how much of each subscription dollar funds sales, marketing, R&D, and profit.
A 10% discount on a 40% margin product requires a 33% volume increase just to maintain total gross profit. Discounts reduce revenue without reducing cost, magnifying their negative impact on profitability. Always calculate the required volume increase before authorizing discounts.
Gross profit is a dollar amount: Revenue minus COGS. Gross margin is a percentage: Gross Profit divided by Revenue. Gross profit in dollars is used for budgeting; gross margin percentage is used for benchmarking and comparing companies of different sizes.
Yes. Many growth-stage companies have positive gross margins but negative net margins because operating expenses (especially sales and marketing) exceed gross profit. This is intentional when investing in growth against long-term subscription or customer lifetime value, but requires external capital to sustain.
Margin = (Selling Price - Cost) / Selling Price. For a $150 selling price and $90 cost: Margin = $60 / $150 = 40%. To find the price needed for a target margin: Price = Cost / (1 - Target Margin). For 40% margin on $90 cost: Price = $90 / 0.60 = $150.
Product mix margin = weighted average across all products by revenue contribution. Shifting revenue toward higher-margin products improves blended margin without changing any product's individual profitability. Many businesses see declining overall margins as growth shifts toward lower-margin commoditized offerings.
For public companies: access SEC filings (10-K) or financial databases (Macrotrends, Wisesheets). For private companies: industry associations and IBISWorld publish industry averages. Also benchmark SaaS companies using the Rule of 40: Revenue Growth Rate + Operating Margin should exceed 40%.
The Rule of 40 states that a healthy SaaS company's revenue growth rate plus profit margin should exceed 40. A company growing at 20% with 25% margin scores 45 — above threshold. It balances growth and profitability into a single metric used by investors to evaluate pre-profitability SaaS companies.
Variable cost reductions improve margins proportionally across all revenue. A 5% COGS reduction on $10M revenue at 40% gross margin raises gross profit from $4M to $4.3M — a 43% gross margin. Common levers: supplier renegotiation, volume discounts, process improvement, and offshore sourcing.
Margin decline causes: input cost inflation, competitive pricing pressure, revenue mix shift toward lower-margin offerings, diseconomies of scale, customer renegotiating lower prices, rising overhead not offset by revenue growth, and seasonality differences between comparison periods.
Scale improves margins in high fixed-cost businesses. Fixed costs as a percentage of revenue shrink as revenue grows, expanding operating margin. A business with $1M fixed costs at $3M revenue has 33% fixed cost burden — at $10M revenue, fixed costs are 10%. Software and financial services benefit most from scale leverage.
CAC is expensed immediately while lifetime value accrues over years. A company with $500 CAC and $2,000 LTV at 75% gross margin creates $1,500 gross profit per customer against $500 investment. Investors accept negative current margins when LTV:CAC exceeds 3, because each acquisition creates positive net value despite temporary compression.
Small business net margins typically range 5-10% across most industries. Service businesses often achieve 10-20% due to low capital requirements. Retail averages 2-6%. Restaurants 3-9%. Small business net margins are often compressed by owner compensation appearing as operating expense and debt service on start-up financing.
Price = Cost / (1 - Desired Margin). For 35% margin on $65 cost: Price = $65 / 0.65 = $100. Verification: ($100 - $65) / $100 = 35%. This formula avoids the common error of applying markup percentage in place of margin percentage, which produces prices too low to hit margin targets.
Branded DTC e-commerce: 40-65% gross margin. Multi-brand retailers: 25-45%. Drop-shipping: 10-30%. After fulfillment (15-25%), customer acquisition (20-40%), and platform fees (3-15%), net margins for healthy e-commerce businesses are often 2-8%. Sub-30% gross margin typically cannot support paid acquisition at scale.
The calculator accepts revenue plus up to three cost tiers: COGS (producing gross margin), operating expenses (producing operating margin), and taxes/interest (producing net margin). Separating costs by tier reveals whether margin problems originate in production cost or overhead, directing improvement efforts correctly.
These four margin concepts are routinely confused in business planning and financial analysis. Misunderstanding any of them leads to pricing errors, misallocated resources, or faulty investment conclusions.
Gross margin subtracts COGS (which may include both variable and fixed manufacturing overhead) from revenue. Contribution margin subtracts only variable costs. A manufacturing business with $10M revenue, $3M variable COGS, and $2M fixed production overhead has 50% gross margin but 70% contribution margin. The distinction matters for break-even analysis and pricing decisions: contribution margin tells you the true incremental profit from each additional unit sold.
Operating margin (EBIT margin) includes depreciation and amortization as expenses. EBITDA margin adds those back, reflecting cash operating profitability. For capital-heavy businesses (manufacturing, real estate, telecom), the difference is substantial — a company with 15% operating margin and $3M of D&A on $20M revenue has 30% EBITDA margin. Investors and acquirers typically pay multiples of EBITDA because it approximates free cash flow before capex, making it the most relevant valuation metric.
Net margin measures accounting profit; free cash flow margin measures actual cash generated. The two diverge when a company has significant non-cash charges (depreciation increases FCF margin above net margin) or heavy reinvestment requirements (capex reduces FCF margin below net margin). A SaaS company with 15% net margin and minimal capex may have 25% FCF margin. A capital-intensive manufacturer with 15% net margin and heavy capex may have -5% FCF margin. For valuation and dividend capacity, FCF margin is the superior metric.
Net profit margin and return on sales (ROS) are identical calculations: both equal Net Income / Revenue. The terms are used interchangeably. However, Return on Equity (ROE) and Return on Assets (ROA) are completely different metrics that include balance sheet denominators rather than revenue. Confusing these ratios — particularly comparing a peer's ROE to your net margin — produces meaningless conclusions. Net margin (=ROS) always uses revenue as the denominator; return metrics use equity or asset bases.
Calculation method:Gross margin = (Revenue − COGS) / Revenue. Operating margin = (Revenue − COGS − Operating Expenses) / Revenue. Net margin = (Revenue − COGS − Operating Expenses − Interest − Taxes) / Revenue. EBITDA margin = (Operating Profit + Depreciation + Amortization) / Revenue. All margin figures expressed as percentages rounded to two decimal places.
