Head-to-head
Gross Margin vs Profit Margin
Both numbers are a percentage of revenue, and they are separated by everything the business spends between buying the product and keeping the money. Gross margin stops at the cost of goods sold: materials, manufacturing, and the freight that put the item on the shelf. Net margin carries on through rent, salaries, marketing, interest and tax, and reports what is left.

The gap between them is the operating business. A company at 40% gross margin and 10.8% net margin is spending roughly three quarters of its gross profit on running itself. Whether that is healthy depends entirely on the industry: a grocery chain runs at 25% gross and 2% net, a software company at 80% gross and 20% net, and neither is doing it wrong.
Gross margin is the more actionable of the two because it responds to things a business can change quickly — price, supplier, product mix. Net margin responds to those as well, but it also absorbs costs that are largely fixed in the short term, which is why a bad quarter can look like a pricing problem when it is really an overhead problem.
The mistake to avoid is comparing either figure across industries. Gross margin says nothing about overhead efficiency, and net margin says nothing about product economics. Quoting one alone invites exactly the wrong conclusion, which is why published benchmarks are almost always reported as a pair.

How To Calculate Gross Margin
Gross margin is gross profit as a share of revenue, and the most common error in using it is confusing it with markup.
Net margin
How To Calculate Profit Margin
Profit margin is the share of revenue left over after cost, computed as revenue minus cost divided by revenue. Everything contentious about the topic comes from a single choice: which number sits on the bottom of the fraction.
How They Differ
| Attribute | Gross margin | Net margin |
|---|---|---|
| What is subtracted | Cost of goods sold only | Everything, down to tax |
| Formula | (Revenue − COGS) ÷ Revenue | Net profit ÷ Revenue |
| What it tells you | Whether the product is priced right | Whether the business makes money |
| Who watches it | Pricing, purchasing and product teams | Owners, lenders and investors |
| Typical range | 25% in retail to 80% in software | 2% in grocery to 25% in software |
| What moves it | Price, supplier cost, product mix | All of the above, plus overhead and debt |
| Sensitivity to volume | Flat — it is a ratio per unit | Improves as fixed costs are spread |
| What it cannot tell you | Whether the business survives | Whether the product is viable |
| Where it appears | Above the operating expenses line | The bottom line of the income statement |
The Same Numbers, Both Ways
A business with $250,000 of revenue, $150,000 of product cost, $60,000 of overhead, $4,000 of interest and a 25% tax rate.
- Revenue
- $250,000
- Cost of goods sold
- $150,000
- Operating expenses
- $60,000
- Interest
- $4,000
- Tax rate
- 25%
| Line | Gross margin | Net margin |
|---|---|---|
| Revenue | $250,000 | $250,000 |
| Cost of goods sold | $150,000 | $150,000 |
| Gross profit | $100,000 | $100,000 |
| Operating expenses | Not subtracted | $60,000 |
| Interest | Not subtracted | $4,000 |
| Tax | Not subtracted | $9,000 |
| Bottom line | $100,000 | $27,000 |
| As a share of revenue | 40.0% | 10.8% |
| Cost per dollar of revenue | $0.60 | $0.89 |
Gross margin is 40.0% — $100,000 of $250,000 left after $150,000 of product cost. Net margin is 10.8%, because $60,000 of overhead, $4,000 of interest and $9,000 of tax come out next. The 29.2 points between them are the entire operating business.
When To Use Each
Gross margin
- You are setting or reviewing the price of a single product and need to know what it contributes.
- You are comparing suppliers or product lines, where overhead is common to all of them and cancels out.
- You are a reseller or manufacturer where cost of goods sold is the dominant cost.
Net margin
- You are assessing whether the business as a whole is profitable, or will be after financing and tax.
- You are a lender or investor looking at debt service and the bottom line.
- You are comparing companies in the same industry, where overhead structures are broadly similar.
Common Questions
Why is net margin so much lower than gross margin?
Because gross margin only removes the direct cost of the product. Every salary, rent cheque, marketing campaign, interest payment and tax bill comes out of what remains, and for most businesses those together are larger than the product cost itself.
Which margin should I use to price a product?
Gross margin. A price has to cover the product and contribute to overhead; net margin is an outcome of the whole business and moves for reasons that have nothing to do with one item. Pricing against net margin usually means pricing against a number you cannot attribute.
Can net margin be negative while gross margin is healthy?
Yes, and it often is during a growth phase. A company can make 60% on every sale and still lose money if its fixed costs are built for a scale it has not reached. That is a volume problem, not a pricing one, and cutting price makes it worse.
Is a higher gross margin always better?
No. Raising price to lift gross margin can shrink volume enough to reduce total gross profit. The metric is a ratio, and a ratio can improve while the business gets smaller — which is why it is always read alongside absolute contribution.
How does markup differ from margin?
Markup divides profit by cost; margin divides it by price. A 50% markup is a 33.3% margin. Confusing the two is one of the most common pricing errors, and it always errs in the optimistic direction.
More Comparisons
- Contribution Margin vs Gross Margin
Gross margin deducts cost of goods sold; contribution margin deducts every variable cost. On $500,000 of revenue with $200,000 of COGS and $75,000 of variable selling costs, gross margin is 60% and contribution margin is 45%.
- Markup vs Margin
Markup divides profit by cost; margin divides it by price. The same $20 profit is 50% markup and 33.3% margin — and the gap widens as the rate rises.
- EBITDA vs Cash Flow
EBITDA of $200,000 becomes $105,000 of operating cash flow once interest, tax and working capital are paid, and $45,000 of free cash flow after $60,000 of capital spending. Only 22.5% of the headline figure survives.
