Gross margin vs net margin
Understand the difference between gross margin and net margin, what each one tells you, and why the two should not be treated as interchangeable profitability metrics.
Gross margin and net margin both describe profitability, but they answer different questions. Gross margin shows how much revenue is left after direct product costs, while net margin shows what is left after the broader cost base is taken into account.
That means gross margin is usually better for understanding unit economics and pricing room, while net margin is better for understanding final business profitability.
Core formulas
Gross Margin = ((Revenue - COGS) / Revenue) × 100, Net Margin = ((Revenue - Total Costs) / Revenue) × 100
Gross margin isolates the relationship between revenue and direct cost of goods sold.
Net margin is broader because it reflects the share of revenue left after total costs, not only direct product costs.
When to use gross margin and when to use net margin
- 1Use gross margin when you need to judge product-level economics, pricing room, or break-even ROAS potential.
- 2Use net margin when the main question is what the business actually keeps after the full cost structure is reflected.
- 3Review both together when revenue looks healthy but the business still feels financially tighter than expected.
- 4Keep cost definitions consistent so the two metrics do not drift across reports.
Worked example: strong gross margin with weaker net margin
- Revenue: $20,000
- COGS: $11,000
- Total costs: $17,000
- Gross margin = 45%
- Net margin = 15%
The product economics may still look healthy at the gross level, but the broader business only keeps 15% after the full cost structure is included. That gap is why both views matter.
What matters in practice
- Gross margin is stronger for unit economics and media planning decisions.
- Net margin is stronger for final business profitability decisions.
- A business can have healthy gross margin and still weak net margin if broader costs are too high.

FAQ
Is gross margin more important than net margin?+
They matter for different decisions. Gross margin is often more useful for pricing and acquisition planning, while net margin is more useful for judging overall business profitability.
Can gross margin improve while net margin gets worse?+
Yes. Gross margin can improve at the product level while broader operating costs or acquisition costs still weaken net profitability.
Which margin should I use for ROAS planning?+
Gross margin is usually the cleaner starting point for ROAS and break-even planning because it ties more directly to unit economics.
