Margin vs. markup — the difference that costs money
Most pricing mistakes come from confusing these two percentages:
Margin % = (Selling price − Cost) ÷ Selling price × 100
Markup % = (Selling price − Cost) ÷ Cost × 100
Buy at ₹100 and sell at ₹150: the markup is 50%, but the margin is only 33.3%. If you target a 50% margin and apply a 50% markup, you lose a third of the profit you planned for.
GST handling
GST is collected on behalf of the government, not earned by you. This calculator removes GST from revenue before computing margin and profit, so your numbers reflect what you actually keep. Toggle the mode to tell it whether your selling price already includes GST.
- Exclusive: GST is added on top of the selling price.
- Inclusive: GST is extracted from the selling price (MRP style).
Break-even and fixed costs
Operating expenses — shipping, packing, ads, rent — are independent of the number of units. Break-even quantity = expenses ÷ gross profit per unit. Anything you sell beyond that is profit. This is why low-margin, high-volume products need extremely tight shipping and return costs.
Healthy margins by business type
- Grocery / FMCG retail: 2–10% net.
- Clothing & accessories: 8–15%.
- Electronics e-commerce: 3–8%; watch for returns.
- Services & software: 20%+.
