Margin Calculator — Calculate Profit Margin, Markup, and Selling Price
Whether you run a Kirana store, an online business, or a manufacturing unit, knowing your profit margin is critical. Margin and markup are often confused, and getting the math wrong can mean pricing your products too low to be profitable. This calculator computes profit margin, markup, profit, cost and selling price — in any direction, and always shows margin and markup together so they cannot be mixed up.
Fill in any two of cost, selling price, profit, margin % or markup %, and the other three work themselves out as you type. Then open the fees panel to subtract marketplace commission, shipping and GST and see what you actually keep — plus your break-even price and the price you would need for a target margin. Perfect for retailers, traders, and small businesses. No signup, no cost.
The things that quietly cost you money
- Margin is not markup. Buy at ₹100, sell at ₹150: that is a 33.33% margin but a 50% markup. Price a product at "50% margin" when you meant markup and you have just given away a third of your profit. Both are always on screen.
- GST is not your money. On a ₹999 price that includes 18% GST, your revenue is ₹846.61 — not ₹999. Margin taken on the tax-inclusive price flatters itself.
- Fees change everything. Buy at ₹400 and sell at ₹999 and you might think that is a 60% margin. After 18% GST, 15% commission and ₹60 shipping, it is 27.97%.
- You cannot average margins. Across a price list, the real margin is total profit ÷ total revenue. Averaging each product's margin ignores how much each one actually sells for, and can be wildly out.
- Margin and markup are one ratio, not two. Enter a margin of 20% and a markup of 30% and the tool tells you they contradict each other, instead of quietly picking one.
