Profit & Loss Calculator
Profit or loss from a cost and selling price, with the margin too.
What it cost you, all in.
What you sold it for.
Enter a cost price and a selling price.
How it works
Profit and loss percentages are always taken on the cost price — buy at ₹100, sell at ₹125, and that's a 25% profit. Margin expresses the same ₹25 as a share of the selling price, which comes to 20%. Both are shown, because quoting one when you meant the other is the most common mistake in this calculation.
Profit% = (SP − CP) ÷ CP × 100 · Margin% = (SP − CP) ÷ SP × 100Example
- Cost ₹1,000, sold ₹1,250 → ₹250 profit, 25% on cost, 20% margin
- Cost ₹200, sold ₹150 → ₹50 loss, 25% loss on cost
For calculation purposes only. Taxes, shipping and overheads aren't included unless you fold them into the cost price yourself.
About this calculator
Enter what something cost you and what you sold it for, and this works out the profit or loss in money and as a percentage. The percentage is taken on the cost price, which is the convention used in commerce syllabuses and in everyday trading talk: buy at ₹100, sell at ₹125, and that is a 25% profit.
Margin is shown separately, because it is a genuinely different number. The same ₹25 gain expressed as a share of the selling price is 20%, and quoting one when you meant the other is the most common mistake in this calculation.
Frequently asked questions
How do I calculate profit percentage?
Profit% = (selling price − cost price) ÷ cost price × 100. Cost ₹1,000, sold ₹1,250 gives (250 ÷ 1,000) × 100 = 25% profit. A negative result is a loss percentage.
What is the difference between profit percentage and margin?
Profit percentage is measured against the cost price; margin is measured against the selling price. A ₹250 gain on a ₹1,000 cost sold at ₹1,250 is a 25% profit on cost but a 20% margin on the sale. Both describe the same trade — they just divide by different numbers.
How do I calculate loss percentage?
The same formula, which returns a negative number when the selling price is lower: cost ₹200, sold ₹150 gives (−50 ÷ 200) × 100 = −25%, a 25% loss. The calculator labels it as a loss rather than showing a minus sign.
Does this include taxes and other costs?
Only if you fold them into the cost price yourself. The calculator works from the two numbers you give it, so add shipping, packaging, commission or overheads to the cost price if you want the profit figure to reflect them.
