Profit Margin Calculator

How the Profit Margin Calculator works

The profit margin calculator computes gross margin, net margin, and markup percentage from your revenue, cost of goods sold (COGS), and operating expenses. It also solves in reverse — enter a target margin and your total costs to find the required revenue (selling price). Entrepreneurs, product managers, and finance teams use it to quickly evaluate pricing decisions and profitability targets.

Gross margin vs net margin

Gross margin = (Revenue − COGS) / Revenue × 100. It measures the efficiency of production and direct delivery before overhead. Net margin = (Revenue − All expenses) / Revenue × 100, accounting for operating expenses, interest, and tax. A business with 60% gross margin but 5% net margin has high overhead relative to its revenue — a signal to investigate fixed cost structure. The calculator separates both metrics so you can diagnose which layer of the P&L needs attention.

Margin vs markup: the key difference

Margin and markup are frequently confused. Margin is profit as a percentage of selling price. Markup is profit as a percentage of cost. A product that costs ₹100 and sells for ₹150 has a 33% margin but a 50% markup. If you quote a “50% margin” when you mean “50% markup,” you will underprice by a significant amount. The calculator shows the markup alongside the margin (and the margin that a given markup produces in the Markup → Price mode) so you can communicate clearly with manufacturers, distributors, and colleagues.

GST impact on Indian businesses

For Indian businesses, GST affects the price customers pay but should not be included in revenue or cost when calculating operating margins — GST is collected on behalf of the government, not retained as income. However, if you are comparing margins against international benchmarks or presenting to investors unfamiliar with Indian tax structure, it is worth noting whether prices in your model are inclusive or exclusive of GST. The calculator works on the figures exactly as you enter them, so enter revenue and costs consistently — all GST-exclusive is the cleanest basis for Indian-context margin analysis.

Target margin reverse calculation

The reverse mode is particularly useful for pricing new products. Enter your target margin percentage and your known costs in the Required Revenue mode — the calculator outputs the minimum revenue (selling price) that achieves that margin. For example, to achieve a 40% gross margin on a product costing ₹600 to make, the minimum selling price is ₹600 / (1 − 0.40) = ₹1,000. This approach ensures pricing decisions start from required profitability rather than guesswork or competitor matching alone.
