Profit margin is the percentage of your revenue that remains as profit after costs. It's the most important metric for assessing the health of your e-commerce business — yet it's frequently misunderstood or miscalculated by new sellers.
Gross Profit Margin vs Net Profit Margin
Gross Profit Margin
Gross profit margin = (Revenue – Cost of Goods Sold) ÷ Revenue × 100. This only accounts for the direct cost of your products. It tells you how much you make before operating expenses like ads, subscriptions, and salaries.
Net Profit Margin
Net profit margin = (Revenue – ALL Costs) ÷ Revenue × 100. This is your real profit after every expense — COGS, platform fees, advertising, shipping, returns, tools, and taxes. Net margin is the number that actually matters.
What's a Good Profit Margin by Business Type?
| Business Model | Healthy Gross Margin | Healthy Net Margin |
|---|---|---|
| Handmade Products (Etsy) | 60–80% | 30–50% |
| Amazon FBA (Private Label) | 40–60% | 20–35% |
| Dropshipping | 30–50% | 10–20% |
| Print on Demand | 40–60% | 20–35% |
| Digital Products | 85–95% | 60–80% |
| Wholesale/Reselling | 20–35% | 10–20% |
Why Margins Vary So Much
Business model is the biggest driver of margin differences. Digital products have near-100% gross margins because there's no cost of goods. Physical products have material and fulfillment costs that cap gross margins. Advertising-dependent models (dropshipping) have lower net margins because the customer acquisition cost is high.
How to Improve Your Profit Margins
- Raise your prices — most sellers are undercharging significantly
- Negotiate better rates with suppliers when you have purchase history
- Reduce returns by improving product descriptions and photos
- Shift budget to your highest-ROAS advertising channels
- Bundle products to increase average order value (AOV)
- Cut underperforming SKUs that tie up cash with low margins
- Move to a platform with lower transaction fees as you scale
Margin vs Revenue: Why Bigger Isn't Always Better
A seller doing $50,000/month with a 30% net margin ($15,000 profit) is in a better position than a seller doing $200,000/month with a 5% net margin ($10,000 profit). Focus on your margin percentage, not just your revenue number.
