The examples start with a simple profit sum and move on to discounts, GST, marketplace fees and unit prices. Every step is shown, so you can follow along with a pen or check the numbers on the free price calculator.

If any term is new, read what is price calculation first. Otherwise, jump straight in.

Quick Reference: The Formulas You Will Use

Need	Formula
Profit	SP – CP
Profit %	Profit / CP x 100
Loss %	Loss / CP x 100
Price from markup	CP x (1 + markup)
Price after discount	List price x (1 – discount)
GST total	Price x (1 + GST rate)
Price before GST	Total / (1 + GST rate)
Unit price	Total price / quantity

Key takeaway: Always identify the base first. Profit percent uses cost, discount uses list price, and GST uses the price before tax.

Example 1: Simple Profit

Manoj buys 50 notebooks at Rs. 18 each and sells them at Rs. 25 each. Cost = 50 x 18 = Rs. 900. Sales = 50 x 25 = Rs. 1,250. Profit = 1,250 – 900 = Rs. 350. Profit percent = 350 / 900 x 100 = 38.89%.

Example 2: Loss on a Clearance Sale

A shop bought 20 jackets at Rs. 900 each and sells them at Rs. 780 in an end-of-season sale. Loss per jacket = 120. Total loss = 20 x 120 = Rs. 2,400. Loss percent = 120 / 900 x 100 = 13.33%. The shopkeeper accepts this to free up space and cash.

Example 3: Price from a Target Markup

A cake shop makes brownies at Rs. 22 each and wants a 60% markup. Price = 22 x 1.60 = Rs. 35.20. The shop rounds this to Rs. 35 and earns Rs. 13 per brownie. On 40 brownies a day, daily profit is Rs. 520.

Example 4: Price from a Target Margin

A bookshop buys a novel at Rs. 240 and wants a 25% margin. Price = 240 / 0.75 = Rs. 320. Profit = Rs. 80, which is exactly 25% of Rs. 320. Had the shop used a 25% markup instead, the price would be Rs. 300, and the margin only 20%.

Example 5: Single Discount

A pair of headphones has an MRP of Rs. 2,499 and is sold at 30% off. Discount = 2,499 x 0.30 = Rs. 749.70. Selling price = 2,499 – 749.70 = Rs. 1,749.30. Using the shortcut, 2,499 x 0.70 = Rs. 1,749.30. Both methods agree.

Example 6: Two Successive Discounts

A television is marked at Rs. 40,000. The shop gives 10% off, and a bank card offer gives another 5% off the reduced price. After the first discount: 40,000 x 0.90 = Rs. 36,000. After the second: 36,000 x 0.95 = Rs. 34,200. The total saving is Rs. 5,800, which is 14.5% and not 15%.

Example 7: Adding GST

A freelance photographer charges Rs. 12,000 for a shoot. With 18% GST, tax = 12,000 x 0.18 = Rs. 2,160, and the client pays Rs. 14,160. On the invoice, the photographer shows the base amount, CGST of Rs. 1,080 and SGST of Rs. 1,080 for an in-state client. The official GST portal explains invoice formats.

Example 8: Removing GST from a Total

A customer pays Rs. 2,950 for a service with 18% GST included. Price before tax = 2,950 / 1.18 = Rs. 2,500. GST = 2,950 – 2,500 = Rs. 450. A common error is to compute 18% of 2,950, which gives Rs. 531 and the wrong split.

Example 9: Marketplace Commission

Sana sells scented candles online. Her cost is Rs. 110 per candle and shipping is Rs. 30. The platform takes a 15% commission on the selling price. She wants Rs. 50 profit. Price = (110 + 30 + 50) / 0.85 = 190 / 0.85 = Rs. 223.53. She lists it at Rs. 225. Check: commission = Rs. 33.75, and profit = 225 – 33.75 – 140 = Rs. 51.25.

Example 10: Unit Price Comparison

A 200 g pack of tea costs Rs. 90, and a 500 g pack costs Rs. 205. The 200 g pack costs 90 / 200 = Rs. 0.45 per gram, which is Rs. 450 per kg. The 500 g pack costs 205 / 500 = Rs. 0.41 per gram, or Rs. 410 per kg. The larger pack saves about 8.9% per gram. If you finish tea within a month, the bigger pack is better value.

Example 11: Finding Cost from Selling Price and Profit

A shopkeeper sells a mixer grinder for Rs. 3,300 and earns a 20% profit on cost. Cost = 3,300 / 1.20 = Rs. 2,750. The profit is Rs. 550. Beginners often take 20% off 3,300, which gives the wrong cost of Rs. 2,640.

Example 12: A Full Chain with Discount and GST

A boutique buys a saree for Rs. 1,800. It wants a 35% markup and plans to show a 10% discount. Price after discount needed = 1,800 x 1.35 = Rs. 2,430. List price = 2,430 / 0.90 = Rs. 2,700. The customer sees Rs. 2,700 less 10%, which is Rs. 2,430. With 5% GST, tax = Rs. 121.50 and the customer pays Rs. 2,551.50.

Example 13: Break-Even Quantity

Break-even tells you how many units you must sell to cover fixed costs. Ritu runs a small tiffin service from a rented kitchen. Her fixed costs are Rs. 12,000 a month for rent, a helper and utilities. Each tiffin sells for Rs. 90 and costs Rs. 55 in food and packing, so each one adds Rs. 35 toward fixed costs. Break-even = 12,000 / 35 = 342.86, so she needs about 343 tiffins a month, or roughly 12 a day, before she earns any profit. Selling 500 tiffins gives a profit of (500 – 343) x 35 = Rs. 5,495. This simple sum shows why volume matters as much as price.

Example 14: Raising a Price Without Losing Profit

A tea powder seller sees raw tea cost rise 8%. Her old cost was Rs. 250 a kg and her price Rs. 300 a kg. The new cost is 250 x 1.08 = Rs. 270. To keep the same Rs. 50 profit per kg, the new price is Rs. 320. That is a price rise of 20 / 300 = 6.67%, which is smaller than the cost rise, because the profit part of the price does not need to grow. To keep the same margin of 16.67%, she would price at 270 / 0.8333 = Rs. 324. She picks Rs. 325 as a round number.

Example 15: Festival Bulk Order Quote

A sweet shop in Varanasi receives an order for 300 boxes of laddoos for Diwali gifts. The cost per box is Rs. 160 including the box and ribbon. The shop wants a 25% margin and offers a bulk price. Price per box = 160 / 0.75 = Rs. 213.33, which becomes Rs. 215 after rounding. Total = 300 x 215 = Rs. 64,500. With 5% GST on sweets, tax is Rs. 3,225 and the invoice total is Rs. 67,725. The buyer gets a clear quote with the tax shown on its own line.

Practice Questions

1. Cost Rs. 640, selling price Rs. 800. Find profit percent.
2. List price Rs. 1,500 with 20% discount. Find the selling price.
3. Price before tax Rs. 4,000 with 18% GST. Find the total.
4. Total Rs. 1,180 with 18% GST included. Find the price before tax.
5. Cost Rs. 300, desired margin 40%. Find the selling price.
6. A 2 kg pack costs Rs. 260 and a 5 kg pack costs Rs. 600. Which is cheaper per kg?

Answers: (1) 25%. (2) Rs. 1,200. (3) Rs. 4,720. (4) Rs. 1,000. (5) 300 / 0.60 = Rs. 500. (6) 2 kg pack is Rs. 130 per kg and 5 kg pack is Rs. 120 per kg, so the 5 kg pack is cheaper.

Benefits of Learning Through Examples

Worked examples show how formulas behave in real situations. After a dozen sums you start to see the same few patterns again and again, which makes new problems feel familiar. Examples also train you to check answers by going backwards, a habit that protects small businesses from costly errors. For students, the examples match the style of profit and loss questions in school, commerce exams and bank tests.

Challenges and Limitations

Examples use clean numbers, while real prices include odd costs and rounding. A beginner may also copy a method without grasping why it works, then fail when the wording changes. Real markets add competition, season and customer mood, which no example captures fully. Treat these cases as practice, and extend them with your own costs.

Common Mistakes to Avoid

1. Using the wrong base. Profit percent is on cost, discount is on list price.
2. Adding discounts. Multiply the factors instead.
3. Finding cost by subtracting a percent. Divide by 1 plus the profit rate.
4. Taking GST from an inclusive total. Divide by 1 plus the rate.
5. Forgetting fees and shipping. Add them before dividing by one minus the commission.
6. Rounding at every step. Keep decimals until the last line.

Best Practices and Expert Recommendations

1. Write the formula first. Then put in the numbers.
2. Check by reversing. Apply the discount or tax again to confirm.
3. Use round-number targets. Rs. 225 reads cleaner than Rs. 223.53.
4. Practise weekly. Do three or four examples with your own products.
5. Use the tool for a final check. Our guide to the price formula explains the rules used here.
6. Keep records. Save your sums so you can reuse them next season.

Conclusion

These twelve examples and six practice questions cover almost every basic pricing situation an Indian seller or student will meet: profit, loss, markup, margin, single and stacked discounts, GST in both directions, marketplace fees and unit prices. Work through them slowly, check each by reversing the steps, and use a calculator only for confirmation. In a short time, pricing sums will feel routine.

FAQs

What is a simple example of price calculation?
If you buy a notebook for Rs. 18 and sell it for Rs. 25, the profit is Rs. 7, which is 38.89% of cost. This is the basic profit percent sum. More complex cases add discount, GST and fees.

How do I calculate a price with 18% GST?
Multiply the price before tax by 1.18. For Rs. 4,000, the total is Rs. 4,720, with Rs. 720 as GST. To go back, divide the total by 1.18.

How do I calculate two discounts together?
Multiply the two factors. A 10% discount followed by 5% gives 0.90 x 0.95 = 0.855, so you pay 85.5% of the list price, a total saving of 14.5%.

How can I find the cost price from a profit percentage?
Divide the selling price by 1 plus the profit rate. If you sell at Rs. 3,300 with a 20% profit on cost, the cost was 3,300 / 1.20 = Rs. 2,750. Do not simply subtract 20% from the selling price.

How do I compare which pack is cheaper?
Divide each price by its quantity to get the unit price. The pack with the lower price per kg, litre or piece is the better value, provided you will use it all.
