Profit Margin Calculator

This profit margin calculator does three jobs in one tool. Give it a selling price and a cost and it tells you the gross profit, the margin percentage and the markup percentage. Flip it around and it works backwards: tell it the margin or markup you want on a given cost, and it returns the exact selling price you should charge. It is built for anyone who sets prices for a living — a Kirana shop owner, a D2C brand founder selling on Amazon and Flipkart, a freelancer quoting a project, a reseller, a restaurant, or a small manufacturer working out a quotation.

The reason both numbers matter is that margin and markup are not the same thing, even though they are often used interchangeably in conversation. They measure the same rupee of profit, but against different bases. Mixing them up is one of the most expensive habits in small business — a shopkeeper who thinks a 25% markup gives a 25% margin is quietly leaving money on the table on every single sale.

Gross profit margin (the income-statement number)

Margin % = (Revenue − Cost) ÷ Revenue × 100

Margin is expressed as a percentage of revenue — the selling price. It is the figure that appears on a profit-and-loss statement and the one your accountant and your bank will ask about. Because the denominator is revenue (which is always larger than cost when you are profitable), margin can never reach 100%.

Markup (the number you add to cost)

Markup % = (Revenue − Cost) ÷ Cost × 100

Markup is expressed as a percentage of cost. It is how most traders actually price on the shop floor — "buy at this rate, add X percent, that's my selling rate." Because the denominator is cost, markup has no upper limit; a 200% markup is perfectly normal in jewellery, fashion and FMCG.

The two are linked, but never equal

You can convert one into the other with these identities:

Markup = Margin ÷ (1 − Margin)  |  Margin = Markup ÷ (1 + Markup)

The table below shows how far apart they drift as profitability rises — the gap is small at low percentages and large at high ones:

Worked example — a D2C product

Suppose you make a scented candle for a landed cost of ₹100 (wax, wick, jar, packaging) and sell it on your website for ₹150.

• Gross profit = ₹150 − ₹100 = ₹50
• Margin = ₹50 ÷ ₹150 = 33.3%
• Markup = ₹50 ÷ ₹100 = 50%

Same ₹50 of profit, two very different percentages. If a marketplace later asks you to fund a "33% off" sale, this calculator instantly shows you whether the discount eats your entire margin — at 33.3% margin, it almost does.

Pricing backwards from a target

If you know the margin you need, set the price with Price = Cost ÷ (1 − Margin% ÷ 100). To earn a 40% margin on a ₹60 cost: ₹60 ÷ 0.60 = ₹100. If you prefer to think in markup, use Price = Cost × (1 + Markup% ÷ 100). A 50% markup on ₹60 gives ₹90 — which is only a 33.3% margin, not 50%. Use the toggle above to switch between these modes.

Key factors and tips for Indian sellers

• Define "cost" honestly. Gross margin uses only the cost of goods sold (COGS) — the direct cost of the product. Rent, salaries, electricity and marketing are operating costs that reduce your net margin, not gross margin.
• GST is not your margin. The GST you collect is passed on to the government, not kept. Always work out price and margin on the pre-tax (taxable) value, then add GST on top.
• Marketplace fees are real costs. Amazon, Flipkart and Meesho take commission, shipping, payment-gateway and return charges. A product that looks like 40% margin in your warehouse can fall to single digits after platform deductions.
• Higher margin ≠ higher profit. A high margin on very few sales can earn less than a thin margin at high volume. FMCG and groceries famously run on low margins and huge turnover.

Common mistakes

• Applying your target margin as a markup. Wanting a 40% margin but only adding 40% markup leaves you at a 28.6% margin.
• Forgetting that discounts come off revenue, so they hit margin harder than markup.
• Confusing gross margin with net margin — strong gross margins can still end in a loss once overheads are paid.
