Gross margin
Gross margin is revenue minus the direct cost of delivering your product or service, expressed as a percentage of revenue. If you generate $500K in revenue and it costs $200K to deliver that revenue, your gross profit is $300K and your gross margin is 60%. This measures the efficiency and profitability of your core offering before accounting for overhead.
Gross margin is what is left after the direct costs of producing your product or service. Revenue minus cost of goods sold, divided by revenue. A SaaS company with $10M revenue and $2M in hosting, support, and payment processing has 80% gross margin. A service business with $10M revenue and $7M in direct service delivery costs has 30% gross margin.
Gross margin is usually the most informative single number about a business model. It tells you how much of every revenue dollar is available to cover fixed costs and produce profit. Businesses with high gross margins (software, marketplaces, digital content) can afford significant investment in growth. Businesses with low gross margins (services, physical goods with thin spreads) have less flexibility.
Net margin
Net margin is the percentage of revenue that remains after all expenses, including overhead, salaries, marketing, and interest. If that same $500K business has $250K in operating expenses on top of the $200K cost of revenue, the net profit is $50K and the net margin is 10%. This measures overall business profitability.
Net margin is what is left after all costs and taxes. Operating expenses, interest, taxes, one-time items, everything. Net margin is the bottom-line profitability of the business. A company can have great gross margin and terrible net margin if operating expenses are out of control, or healthy net margin with thin gross margin if operating expenses are tightly managed.
Public companies are usually compared on net margin because that is the ultimate return to shareholders. Private growth companies are often judged more on gross margin because they are deliberately running at low net margin to invest in growth. Both numbers matter, but they answer different questions.
What the gap between them tells you
The gap between gross margin and net margin is your overhead burden. A business with a 60% gross margin and a 10% net margin is spending 50% of revenue on overhead. Whether that's appropriate depends on the stage and growth trajectory. High-growth companies often have large overhead relative to gross profit because they're investing ahead of revenue. Mature businesses should have tighter ratios.
The gap between gross margin and net margin is where operating expenses live. A company with 70% gross margin and 10% net margin is spending 60 cents of every revenue dollar on sales, marketing, R&D, and G&A. That could be appropriate investment in growth, or it could be bloat. The context determines whether the gap is healthy or concerning.
Looking at the gap over time is often more informative than the level at any point. If the gap is shrinking (operating expenses growing faster than gross profit), the business is getting less efficient. If it is widening (operating expenses growing slower than gross profit), operating leverage is kicking in. Either direction has implications for how to plan the next period.
Benchmarking your margins
Margins vary enormously by business model. SaaS businesses often target 70-80% gross margins. Professional services firms typically run 40-60%. Physical product businesses might be in the 30-50% range. Net margins also vary widely, a 10-20% net margin is healthy for a service business; a 3-5% net margin might be acceptable for a high-volume, low-touch model. The important thing is to know your margins, know the benchmarks for your model, and understand why you're above or below them.
Benchmarking needs industry context. 70% gross margin is average for SaaS, terrible for retail, and excellent for services. A 15% net margin is unremarkable for a large public software company, strong for a bootstrapped service business, and concerning for a mature retailer. Comparing your margins to the wrong reference set produces misleading conclusions.
The most useful benchmarks are public companies in your specific segment, not broad industry averages. Pull the last 4 quarters of gross and net margin for 5-10 comparable public companies. That range is what your board and investors will compare you to. Being at the low end for a growth-stage company is fine. Being at the low end for a mature company signals a problem.
