How to Calculate Profit Margin for Your Shop — With Real Examples
2026-06-16 · 7 min read
"Aaj Rs. 50,000 ki sale hui" feels great — but sales are not profit. Many Pakistani shop owners work hard all month and still wonder where the money went. The answer is almost always in the margin. Here's how to actually calculate it.
Sales ≠ Profit: The Costly Confusion
If you sold Rs. 50,000 of goods but those goods cost you Rs. 40,000 to buy, your gross profit is Rs. 10,000 — not Rs. 50,000. And that's before rent, electricity, and other costs. Confusing revenue with profit is the single most common reason shops feel busy but never seem to save money.
The Simple Profit Margin Formula
There are two numbers worth knowing:
- Gross Profit = Selling Price − Cost of Goods
- Profit Margin (%) = (Gross Profit ÷ Selling Price) × 100
Worked example: You buy a product for Rs. 800 and sell it for Rs. 1,000.
- Gross Profit = 1,000 − 800 = Rs. 200
- Profit Margin = (200 ÷ 1,000) × 100 = 20%
So every Rs. 1,000 sale puts Rs. 200 of gross profit in your pocket — before expenses. If your monthly rent, bills, and salaries come to Rs. 80,000, you need Rs. 400,000 in sales at this margin just to break even.
The Hidden Costs Most Owners Forget
Your real margin is lower than the simple formula suggests, because of costs that never make it into the calculation:
- Spoilage and expiry — unsold perishables are pure loss.
- Udhaar that's never repaid — a "sale" that never becomes cash.
- Electricity for refrigeration and other running costs tied to specific products.
- Breakage, theft, and giving extra "thora sa" to regulars — small leaks that add up.
Subtract these, and a "20% margin" product might really be earning you 12–14%. Knowing the true number is what separates shops that grow from shops that just survive.
Stop Guessing — Let the System Calculate It
Working this out by hand at month-end is slow and easy to get wrong. When you record sales and purchase costs in PaakiShop's POS software, it knows the cost and selling price of every item — so it shows your real profit automatically. The daily WhatsApp report even sends you the day's actual profit each evening, instead of you estimating once a month and hoping. That's the difference between running your shop on facts and running it on feelings.
