What Is Profit Margin?
Revenue tells you how much came in; margin tells you how much stayed.
Profit margin is the share of revenue a business keeps as profit, written as a percentage rather than a rupee figure. Divide profit by revenue and multiply by 100, and the answer tells you how many paise out of every rupee of sales survived the costs behind it.
Which profit you divide by decides everything. An Indian retailer can quote 45% and 6% in the same breath and be honest both times, because the two count different costs.
The Three Margins and What Each One Counts
The sum never changes: Profit Margin (%) = (Profit divided by Revenue) x 100. Only the top figure moves.
| Margin | Profit it uses | What it answers |
|---|---|---|
| Gross | Revenue minus cost of goods sold | Is your pricing beating your stock cost |
| Operating | Gross profit minus rent, salaries, power, marketing | Does the day-to-day operation work |
| Net | Operating profit minus interest, depreciation and tax | What the owner is left holding |
None of the three can be worked out without:
- Revenue for the period, taken before tax
- The cost of the goods behind that revenue
- Every running cost, from rent to delivery commission
Gross margin is a pricing number, tracked item by item in a margin report. Net margin is the owner’s number, closing out the profit and loss report.
Difference Between Profit Margin and Markup
Sell something for Rs 180 that cost you Rs 120 and you have added a 50% markup while earning a 33.3% margin. Same sixty rupees, two very different percentages.
| Aspect | Margin | Markup |
|---|---|---|
| Divides by | Selling price | Cost price |
| Example | 60 / 180 = 33.3% | 60 / 120 = 50% |
| Answers | Share of sales you keep | Amount added on top of cost |
| Used for | Reporting and comparison | Setting a price |
At Petpooja the mix-up we run into most often with owners is a markup quoted as a margin, which always flatters the business. Markup suits pricing decisions, and a pricing calculator template is built around it, but a bank wants the margin.
Profit Margin Example
Take an illustrative garment store in Adajan, Surat, closing its books for June 2026. Expenses means rent, salaries, power and marketing; other costs covers interest, depreciation and tax.
| Line | Amount (Rs) | Margin % |
|---|---|---|
| Revenue | 9,36,500 | 100% |
| COGS | 5,15,100 | 55.0% |
| Gross profit | 4,21,400 | 45.0% |
| Expenses | 3,18,700 | 34.0% |
| Operating profit | 1,02,700 | 11.0% |
| Other costs | 44,600 | 4.8% |
| Net profit | 58,100 | 6.2% |
Note: this is an invented example for illustration only. The outlet and every figure in it are made up, and they are used purely to show how the three margins come off the same revenue.
Look at the spread. Nearly 39 percentage points separate the top margin from the bottom, and both describe the same month. Quote 45% to a lender and you are not lying, but you are not describing the business either.
Why Your Margin Slips While Sales Climb
Margin is a ratio, so it falls the moment costs grow faster than revenue. Sales can rise every month while the percentage drops, and a new aggregator commission is the usual cause.
Tax rules push the same way. Most standalone restaurants bill at 5% GST with no input tax credit under CBIC’s GST rules, so the GST paid on rent, packaging and commission cannot be set off and stays inside the cost base. A retailer claims that input credit back. A restaurant on this rate cannot.
Then there is the stock itself. A single point of slippage on a Rs 9.36 lakh month is Rs 9,365 gone, whether from a supplier price rise or a discount nobody signed off. Kitchens run the same discipline under food cost, where most fixes sit in reducing food cost.
Raising prices is the other lever, and menu pricing strategies is where that starts.
Find the Best Profit Margin Reports
Margin is easy arithmetic. Trusting the two numbers you feed it is the hard part, and that is where hand-copied sales break down.
For restaurants, Petpooja POSS records every bill and deducts stock item by item, and its 80+ business reports cover sales, inventory consumption and payments. For retail businesses, Petpooja Invoice carries the reporting further, monitoring revenue, expenses and profits and producing detailed profit and loss statements.

Frequently Asked Questions
No. Margin divides profit by the selling price, while markup divides the same profit by the cost price, so markup always looks like the bigger number. A 50% markup is only a 33.3% margin.
There is no single figure worth chasing, because it shifts with format, rent, debt and aggregator dependence. Track your own margin for four or five months and judge the direction rather than the number.
Net margin, almost always. Gross margin flatters the business by ignoring rent, salaries and interest, and any lender reading your net profit report will work the real figure out anyway.
Yes, and it is more common than owners admit. If costs for the period exceed revenue, the percentage turns negative, which simply says the business paid to trade that month.
It should not. GST you collect is money held for the government, not income, so revenue for a margin calculation is the pre-tax figure. Including it inflates the denominator and understates your real margin.
