The Formulas

Gross Profit = Revenue − Cost of Goods Sold
Net Profit = Revenue − ALL Expenses (COGS + operating costs + marketing + taxes, etc.)

Example

Revenue: $100,000. COGS: $45,000. Operating expenses (marketing, salaries, rent, fees): $42,000.

Gross Profit = $100,000 − $45,000 = $55,000 (55% gross margin)

Net Profit = $55,000 − $42,000 = $13,000 (only 13% net margin)

Why the Gap Matters

A healthy gross margin with a thin net margin means operating costs are eating most of the profit. A different problem (and different fix) than a thin gross margin, which points to pricing or COGS instead. Diagnosing the right one first prevents fixing the wrong number.

Checklist

Calculate gross profit as revenue minus cost of goods sold
Calculate net profit as revenue minus all expenses
Compare gross margin percentage against net margin percentage
Diagnose whether a low margin is a pricing/COGS issue or an operating-cost issue
Track both margins over time, not just at a single point
Use the correct margin when making the corresponding decision

Common Mistakes

Using gross and net profit interchangeably. They describe very different financial pictures, and treating them as the same number leads to misdiagnosing problems.

Fixing operating costs when the real problem is pricing. A thin gross margin needs a pricing or cost-of-goods fix, not an operating-expense cut.

Only ever looking at net margin. This can obscure whether the core product economics are actually healthy before overhead is applied.

Not tracking the gap between the two margins over time. A widening gap signals growing operating costs that deserve direct attention.

FAQ

What's the difference between gross and net profit?

Gross profit is revenue minus cost of goods sold. Net profit is revenue minus every expense, including operating costs, marketing, and taxes.

Why does confusing the two lead to bad decisions?

A healthy gross margin with a thin net margin points to an operating-cost problem, while a thin gross margin points to a pricing or cost-of-goods problem. Mixing them up means fixing the wrong thing.

Can two businesses with the same revenue have very different margins?

Yes. A 40% gross margin and a 40% net margin describe two very different financial situations, and the gap between them says a lot about where money is actually going.

Which margin matters more for pricing decisions?

Gross margin, since it reflects the direct cost of what's sold before overhead is factored in, making it the more direct pricing signal.
