Use this free profit margin calculator for India to work in INR: find gross margin percentage and markup on cost, back-solve selling price from cost and target margin, and see how list-price discounts erode profitability. It is built for quick pricing and product margin checks—shops, D2C brands, consultants quoting projects, and anyone comparing COGS to ticket price before overheads and tax.
Margin, markup, and discounts
Gross margin (often called profit margin on selling price) is gross profit divided by revenue—the share of each rupee of sales that remains after direct costs. Markupis the same profit expressed as a percentage of cost. Retailers and manufacturers use both; margin aligns with how you read a P&L, while markup is common when pricing from supplier cost.
Core formulas
Margin % = (Revenue − Cost) / Revenue × 100
Markup % = (Revenue − Cost) / Cost × 100
Selling price from cost and margin: Revenue = Cost / (1 − Margindecimal), when margin is measured on revenue.
Margin after discount = (discounted price − cost) / discounted price.
Margin when you discount the list price
If you first set a list price that delivers a chosen gross margin, then offer a percentage discount off that list price, your true margin on the transaction drops. When margin and discount are both expressed as decimals of list (same basis), a compact relationship is:
For example, a 20% margin with a 10% discount gives roughly 11.1% new margin. Our "Margin + discount on list" mode builds list price from cost and your target margin, then applies your discount.
How to use the toggles
- Pricing tools — Derive selling price from cost and either margin % or markup %, or enter revenue and cost to see margin and markup together.
- Margin after discount — Enter list price, discount %, and cost to get price after discount and margin on that discounted price.
- Margin + discount on list — Enter cost, the gross margin you would earn at full list price, and the discount off list; see list price, discounted price, and true margin.
GST, MRP-style list prices, and net margin
Indian sellers often think in MRP or pre-GST cost depending on channel. This tool does not file taxes—it only arithmetic. Pick one convention (both figures inclusive of GST, or both exclusive) and stick to it so your percentage margin matches your books. Net profit margin after rent, salaries, ads, and payment-gateway fees needs a separate layer; here we stay at gross level on direct cost.
Frequently asked questions
Is margin the same as markup?
No. Margin is profit as a percentage of selling price (revenue). Markup is profit as a percentage of cost. For the same deal, markup reads higher than margin when both are positive, because profit is divided by a smaller base (cost) for markup than for margin (revenue).
How do you calculate gross profit margin percentage?
Gross margin % is (Selling price − Cost) ÷ Selling price × 100. It is the share of each rupee of revenue left as gross profit before operating expenses.
How do you calculate selling price from cost and target margin?
Selling price = Cost ÷ (1 − margin as a decimal). Example: 40% margin means divide cost by 0.60 so gross profit equals 40% of revenue.
How does a discount affect profit margin?
A discount lowers revenue while cost usually stays fixed, so margin falls. Margin on the deal is (Price after discount − Cost) ÷ Price after discount. If discount is a fraction of list and you knew margin on list, updated margin can be written as (Old margin − Discount) ÷ (1 − Discount) using decimals—see the formula block above.
Why does a small discount cut margin by more than it sounds?
Margin uses revenue in the denominator. Shrink revenue and the same rupee cost eats a larger share of sales, so the percentage drops faster than the headline discount—worst when you were already on thin margins.
Does this calculator include GST, and can I use INR?
Amounts are in rupees by default. GST is not modelled separately: enter cost and price both inclusive of GST or both exclusive so margin matches how you recognise revenue and COGS.
Is gross margin the same as net profit margin?
No. Gross margin only subtracts direct cost (COGS) from revenue. Net margin also removes rent, payroll, marketing, depreciation, and tax—use this tool for contribution on the product or line item, not full company profitability.
What should I enter as cost (COGS)?
Use landed cost for goods (purchase + inbound freight, duty if you include it consistently), or fully loaded unit cost if you bundle packaging. For services, use the direct cost to deliver one engagement if you are pricing that way; overheads stay outside gross margin unless you deliberately allocate them.
When is markup more useful than margin?
Markup is natural when you start from supplier or make cost and say “I need 60% on top of cost.” Margin is natural when you set a shelf price and want profit as a percent of that price—or when reading financial statements and category benchmarks.
