It's how traders, wholesalers and many shops price: a fixed percentage over landed cost. Switch the mode to work backwards: enter the cost and the price you already charge, and the calculator gives the markup and the margin. INR 1,250 cost and INR 1,500 price is a 20% markup but only a 16.7% margin. GST goes on top of your selling price, not into the markup. If you're registered, choose the rate and the calculator shows the bill the customer pays. The GST you paid on purchases comes back as input tax credit, so enter cost before GST. The conversion table shows common markups and the margin each produces, priced on your cost. It's handy when a buyer quotes margins and your supplier quotes markups. Selling price = cost x (1 + markup / 100); Margin = markup / (100 + markup) x 100 Markup (price − cost) / cost x 100 ## Worked example: Rakesh, hardware shop in Nagpur, checking a supplier deal Rakesh buys a drill at INR 1,250 before GST and sells it at INR 1,500. That's a INR 250 profit, a 20% markup on cost but a 16.7% margin on the price. With 18% GST, his customer pays INR 1,770. To earn the 25% margin his other lines make, he'd need a 33.3% markup, a price of about INR 1,667. Markup on cost 20% Margin on price: 16.7% Profit per unit**INR 250.00** Margin on price**16.7%** Customer pays**INR 1,770.00** Cost INR 1,250.00 \+ Markup (20% of cost) INR 250.00 Selling price before GST INR 1,500.00 \+ GST at 18% INR 270.00 Bill to the customer INR 1,770.00 Markup is charged on GST-exclusive cost. If you're registered, the GST you paid on purchases comes back as input tax credit, so it isn't part of cost.

A supplier promising '25% margin' is offering more than one promising '25% markup'. - Build freight, loading and any non-creditable tax into landed cost before applying markup, or your real markup will be lower than planned. - Under the Legal Metrology rules, the MRP on packaged goods must include GST. If you print MRPs, compute them from your price plus GST. - A uniform markup across all products is simple, but slow-moving stock usually needs a higher one to pay for the time it sits on the shelf. ## Frequently asked questions How do I calculate selling price from cost and markup? Multiply cost by (1 + markup / 100). With a cost of INR 800 and a 25% markup, the price is INR 800 x 1.25 = INR 1,000. Add GST on top of that price for the final bill. How do I convert markup to margin? Margin = markup / (100 + markup) x 100. A 50% markup is a 33.3% margin; a 100% markup is a 50% margin. To go the other way, markup = margin / (100 − margin) x 100. What markup do retailers usually use in India? It varies by category. Groceries often run at 10% to 20% markup, apparel and footwear at 50% to 100% or more, and electronics at single digits to 15%. Your markup must cover rent, staff, wastage and your own profit. Is markup calculated before or after GST? Before. Markup applies to the GST-exclusive cost to give a GST-exclusive price, and GST is then charged on that price. Applying markup on a GST-inclusive cost overprices the product if you're registered and can claim credit. ## Sources and assumptions - [CBIC GST portal](https://cbic-gst.gov.in/) Rules and rates last checked on 25 October 2026.
