Gross Margin vs Net Margin

The short version

• Gross margin = (Revenue − COGS) ÷ Revenue. It tells you whether your products are profitable.
• Net margin = Net Profit ÷ Revenue. It tells you whether your business is profitable.

Why both matter

You can have a high gross margin and a low (or negative) net margin if your overhead is too heavy. You can also have a thin gross margin and still earn a decent net margin if you run extremely lean and sell large volumes — but you have very little safety net.

Practical example

Two small businesses, same revenue of $100,000:

• Café A: COGS $30,000 → Gross margin 70%. Operating costs $60,000. Net profit $10,000. Net margin 10%.
• Grocer B: COGS $75,000 → Gross margin 25%. Operating costs $18,000. Net profit $7,000. Net margin 7%.

The café earns more per dollar but carries a heavier overhead. The grocer turns over thin margins on each item but keeps the structure light.

Which one to focus on

• If your gross margin is weak, fix pricing or COGS first — nothing downstream can save it.
• If your gross margin is healthy but net margin is poor, look at operating expenses.

Common mistakes

• Optimising one without the other. Slashing overhead in a low-gross-margin business can be like rearranging deck chairs.
• Benchmarking against the wrong industry. Healthy margins differ enormously by sector.
