Gross profit vs. net profit: two margins, two questions
Gross profit measures pricing against direct costs; net profit measures the whole operation. How to compute both margins, what each one answers, and typical ranges by illustrative industry.
Gross profit is revenue minus cost of goods sold — what each sale leaves behind after its direct costs. Net profit (net income) is what remains after everything: overhead, interest, depreciation, taxes. Divide each by revenue and you get the two margins, and they answer different questions. Gross margin asks: is the thing I sell priced right against what it costs me to deliver? Net margin asks: does the whole operation, overhead included, make money?
The computation, side by side
Take an illustrative firm with $200,000 of quarterly revenue, $80,000 of COGS, and $60,000 of operating expenses, $10,000 of interest and depreciation:
| Measure | Formula | Amount | Margin |
|---|---|---|---|
| Gross profit | 200,000 − 80,000 | 120,000 | 60% |
| Operating income | 120,000 − 60,000 | 60,000 | 30% |
| Net profit | 60,000 − 10,000 | 50,000 | 25% |
The gap between the two margins — here, 35 points — is the cost of running the business itself. Watch all three layers over time; a full walkthrough of the statement that produces them is in how to read a P&L, and the boundary between COGS and overhead (which determines where the gross line falls) is in COGS vs. operating expenses.
Why the split matters diagnostically
A business whose gross margin is eroding has a pricing or direct-cost problem: supplier increases, labor inefficiency, discounting. More sales volume will not fix it — each sale carries the defect. A business whose gross margin is fine but whose net margin is eroding has an overhead problem, and the fix is spending discipline or spreading fixed costs over more revenue. Misdiagnosing one as the other wastes months.
Typical shapes by industry
Margins are industry-shaped; compare within your kind, not across it (illustrative mid-2026 ranges, not benchmarks to hit):
| Illustrative business | Typical gross margin | Typical net margin |
|---|---|---|
| Restaurant | 60–70% (food cost basis) | 3–6% |
| Retail shop | 30–50% | 2–6% |
| Construction trade | 20–35% | 5–10% |
| Consulting / professional services | 50–70% | 15–30% |
| Software / digital products | 75–90% | 10–30% |
A restaurant with a 5% net margin may be excellently run; a consultancy at 5% has a problem. Note also that owner compensation blurs small-business net margins — a sole proprietor taking draws shows inflated net profit because the owner's labor is unpaid on paper. The IRS self-employed tax center treats that profit as the owner's earnings for tax; for management purposes, charge yourself a market wage before judging the margin.
One habit closes the loop: express every P&L line as a percent of revenue each month — the common-size format described in common-size statements — and both margins, plus every driver of them, fall out automatically.
Frequently asked questions
- How do I calculate gross profit margin and net profit margin?
- Gross margin is (revenue − cost of goods sold) ÷ revenue. Net margin is net income ÷ revenue. A business with $200,000 revenue, $80,000 COGS, and $30,000 net income has a 60% gross margin and a 15% net margin. Compute both monthly; each answers a different question.
- Is a low gross margin or a low net margin worse?
- A low gross margin is usually harder to fix, because it means pricing barely covers direct costs — every additional sale brings little to fund overhead. A low net margin with a healthy gross margin means the operation earns well per sale but overhead absorbs it, which spending discipline or scale can correct.
- What is a good profit margin for a small business?
- There is no universal number — margins are industry-shaped. Restaurants and retailers commonly run net margins in the low single digits; service firms and software businesses can sustain 15–30% or more. The useful comparison is your own trailing average and businesses of your type, not an all-industry figure.
