A shopkeeper buys a shirt for Rs 700 and sells it for Rs 1,000. Ask him his margin and he will likely say 42% — but that is the markup, not the margin, and the mix-up quietly distorts every pricing decision he makes. Confusing these two numbers is one of the most common and most expensive mistakes in small business.

Margin vs Markup: The Difference That Matters
Margin and markup both describe profit as a percentage, but they divide by different numbers — and that changes everything. Profit margin = (profit ÷ selling price) × 100. It answers: of every rupee the customer pays me, how much do I keep? Markup = (profit ÷ cost) × 100. It answers: how much do I add on top of what I paid?
Take cost Rs 700, price Rs 1,000. Profit is Rs 300. Margin = 300 ÷ 1,000 = 30%. Markup = 300 ÷ 700 = 42.9%. Same profit, two very different percentages — markup is always higher than margin on a profitable sale. The danger comes when someone targets a 40% margin but prices using a 40% markup: a 40% markup on Rs 700 gives a price of Rs 980 and a margin of only 28.6%, missing the target badly.
Use margin when you talk about business health, compare with competitors, or report performance — it is the standard language of profitability. Use markup when you set prices from costs, which is how most retailers actually work day to day. Investopedia’s guide to gross profit margin explains the standard definitions used across the industry: Investopedia — Gross Profit Margin. Just never mix the two in the same sentence without saying which you mean.
What Is a Good Profit Margin
There is no universal good number — a 5% margin can be excellent in one trade and fatal in another. Grocery retail often runs on 1–3% margins and survives on volume; software and digital products can exceed 70% because each extra sale costs almost nothing. What matters is your industry’s norm and your own trend over time.
For small Pakistani businesses, rough benchmarks help: retail and trading typically aim for 15–30% gross margins, food businesses 50–70% on individual items (before rent and staff), and services 30–60% depending on labour intensity. If your margin sits well below others selling the same thing, you are either underpricing or overpaying for inputs — both fixable. Track your blended margin monthly using the comparison table above; a slow decline is an early warning that costs are creeping up or discounting is eating your profit.
Remember this calculator shows gross margin per unit — it does not subtract rent, salaries, utilities, or taxes. Your net margin (what the business truly keeps) will always be lower. If the gross margin looks healthy but the bank balance disagrees, the leak is in overheads, not pricing.
Five Ways to Improve Your Margin
1. Raise prices selectively. A 5% price increase on a 30%-margin product lifts margin to about 33% — and most customers will not notice small, well-timed increases. Test on your least price-sensitive items first.
2. Renegotiate input costs. Suppliers expect annual negotiation. Even a 3% cost reduction flows almost entirely to profit. Buying in slightly larger quantities or paying a little earlier for a discount both work.
3. Cut the tail. Products with the thinnest margins often consume the most time. Dropping or repricing your worst performers lifts the blended average faster than squeezing winners.
4. Reduce discounting. Every 10% discount needs roughly a 50% sales increase to break even on a 20%-margin product. Train staff to offer value (bundles, service) instead of price cuts.
5. Watch shrinkage and waste. In retail and food, spoilage, damage, and theft silently erase margin. Measuring waste weekly is unglamorous and extremely profitable.
Profit Margin Calculator: Frequently Asked Questions
What is the difference between margin and markup?
Margin divides profit by the selling price; markup divides profit by the cost. On a Rs 700 cost and Rs 1,000 price, the profit of Rs 300 gives a 30% margin but a 42.9% markup. Margin tells you what share of revenue you keep, while markup tells you how much you added over cost. Use margin for reporting profitability and markup for setting prices — just never confuse the two, because markup is always the bigger number.
What is a good profit margin for a small business?
It depends on the industry. Retail and trading often target 15–30%, food businesses 50–70% per item before overheads, and services 30–60%. Compare yourself against similar businesses rather than chasing a universal number, and track your own trend monthly. This profit margin calculator shows gross margin per unit; your net margin after rent, salaries, and taxes will be lower, so treat the result as a starting point, not the full picture.
How do I calculate margin from the selling price?
Subtract your cost from the selling price to get profit, then divide profit by the selling price and multiply by 100. For example, a Rs 1,000 selling price with a Rs 700 cost gives Rs 300 profit, and 300 divided by 1,000 equals a 30% margin. Enter any two of cost and price into the calculator above and it does the arithmetic instantly, including the markup figure most people mix up.
What is the profit margin formula?
The gross profit margin formula is (Revenue minus Cost of Goods Sold) divided by Revenue, multiplied by 100. For a single unit, that simplifies to (Selling Price minus Cost) divided by Selling Price, times 100. The markup formula is similar but divides by Cost instead of Selling Price. Keep both formulas handy: margin for measuring performance, markup for setting prices from costs.
Why is my margin high but my business still struggling?
Because margin per unit ignores overheads. A 40% gross margin means nothing if rent, salaries, utilities, loan payments, and taxes consume 45% of revenue. This is the difference between gross margin and net margin. Use this profit margin calculator to get pricing right, then do a separate monthly review of fixed costs. If the business bleeds cash despite healthy unit margins, the problem is overhead — not price.
