Profit & loss results are estimates for planning and should be checked against current official rules or professional advice where applicable.
You bought a product for Rs 800 and sold it for Rs 1,000. You made Rs 200, but is that 20% or 25%? The answer depends on whether you measure against cost or selling price. This profit and loss calculator gives you the amount, the percentage on cost and the margin, all at once.
Enter the cost price and selling price. If the selling price is higher, the result shows profit. If it is lower, the result shows a loss and the loss percentage. Shopkeepers, resellers and students preparing for aptitude tests all use the same few formulas.
Every result comes from two inputs: cost price (CP) and selling price (SP). Here are the core formulas taught in school maths and used in everyday trade.
Profit case: CP Rs 800, SP Rs 1,000. Profit is Rs 200. Profit on cost is 25%, while margin on sale is 20%.
Loss case: CP Rs 1,200, SP Rs 1,050. The loss is Rs 150, which equals a 12.5% loss on cost.
Pricing case: an item costs Rs 650 and you want 30% profit on cost. Multiply 650 by 1.3 to get a selling price of Rs 845.
Markup is profit measured against cost. Margin is profit measured against the selling price. The same rupee profit gives two different percentages, and mixing them up leads to underpricing. Retailers often quote margin, while school textbooks usually mean markup when they say "profit percent".
| Markup on cost | Equivalent margin on sale | Example (CP Rs 100) |
|---|---|---|
| 20% | 16.67% | SP Rs 120 |
| 25% | 20% | SP Rs 125 |
| 50% | 33.33% | SP Rs 150 |
| 100% | 50% | SP Rs 200 |
Notice that margin can never reach 100%, but markup can go well beyond it. A seller who wants a 50% margin needs a 100% markup.
Shops often mark up an item and then offer a discount. Say the cost is Rs 500 and the marked price is Rs 800. A 15% discount brings the final price to Rs 680. Your profit drops from Rs 300 to Rs 180, which is 36% on cost. Enter Rs 680 as the selling price for a true figure.
The maths is simple, so most errors come from the inputs. Watch for these before trusting the number on screen.
The result covers gross figures on one transaction. Net profit for business accounts and tax filing needs rent, salaries and overheads too. An accountant can help with that view.

Divide the profit by the cost price and multiply by 100. If you buy at Rs 400 and sell at Rs 500, the profit is Rs 100. So the profit percentage is 100 divided by 400, times 100, which equals 25%.
Profit percentage usually uses cost price as the base, while margin uses selling price. A Rs 200 profit on a Rs 800 cost is 25% profit but only a 20% margin. That is because the selling price of Rs 1,000 is the larger base.
Multiply the cost price by one plus the profit rate as a decimal. For a cost of Rs 1,500 and a 20% target, multiply 1,500 by 1.2. That gives a selling price of Rs 1,800.
Loss percentage is the loss divided by the cost price, multiplied by 100. Selling a Rs 2,000 item for Rs 1,700 creates a Rs 300 loss. That works out to a 15% loss on the original cost.
Be consistent and use either GST-inclusive or GST-exclusive figures on both sides. Registered businesses that claim input tax credit usually calculate profit on prices excluding GST. The tax simply passes through to the government.
Yes, profit on cost can exceed 100% whenever the selling price is more than double the cost. Buying at Rs 300 and selling at Rs 750 gives a Rs 450 profit. That is a 150% profit on cost.
It works well for checking answers to profit and loss questions in bank, SSC and placement tests. Most of those questions measure profit on cost price, so read the question carefully before choosing which percentage to compare.
