What Is Profit Margin? Why Your Ecommerce Business Will Die Without Understanding It
Every seller who has ever said “my product sells well but I am not making money” is describing a profit margin problem. They are generating revenue without generating profit.
This is more common than you think. And it kills businesses that look successful from the outside.
The 3 Types of Profit Margin You Need to Know
1. Gross Profit Margin
This is the most commonly used — and most commonly misunderstood — margin number.
Formula: (Selling Price − Cost of Goods Sold) ÷ Selling Price × 100
COGS here means the landed cost of your product: manufacturing + shipping + duties + packaging. It does not include platform fees or advertising.
A ₹599 product with ₹180 landed cost has a gross margin of 69.9%. Sounds fantastic. But that is not your profit.
2. Net Profit Margin
This is the number that matters. It includes everything:
Net Profit = Selling Price − Landed Cost per unit − Platform commission (12–17% on Amazon/Flipkart) − GST on commission (18% of commission) − Fulfilment / Easy Ship fee (₹35–120) − Closing fee (₹2–25) − Advertising cost per unit sold (total PPC ÷ units sold) − Returns cost allocation (return rate × return shipping cost ÷ units) − Storage cost allocation − Customer support / overhead allocation
Run this calculation on that ₹599 face wash and your real net margin is typically 18–28% — not 70%.
3. Contribution Margin
Used to decide whether to keep selling a product. If contribution margin is positive, the product is paying for at least its own variable costs. If it is negative, every unit you sell makes you poorer.
Formula: Selling Price − All Variable Costs per unit
Variable costs = COGS + commission + shipping + ads + return allocation. Fixed costs (brand registration, ERP software, warehouse rent) are excluded here.
Why Indian Sellers Calculate the Wrong Margin
The fake margin calculation that kills businesses:
Margin = (₹599 − ₹180) ÷ ₹599 = 70% ✗ WRONG
The real margin calculation:
Margin = (₹599 − ₹180 − ₹89.85 − ₹16.17 − ₹65 − ₹8 − ₹35 − ₹18) ÷ ₹599 = 31.2% ✓ REAL
The difference is 38.8 percentage points. If you were pricing for a 70% margin, you are actually earning 31%. And after taxes and overheads, your take-home is closer to 18–22%.
What Is a Healthy Profit Margin for Indian Ecommerce?
| Net Margin | Assessment | Action |
|---|---|---|
| Below 10% | ⚠️ Danger zone | Reprice or find cheaper source |
