Profit Calculator
This profit calculator works out how much you earn on a product or a deal. Enter the cost price, the selling price and how many units you sell, and it shows the profit per unit, the total profit, the margin percentage and the markup percentage. You can also add other expenses — delivery, packing, fees — to see your true net profit.
| Profit per unit | |
| Total revenue (selling price × quantity) | |
| Total cost of goods (cost × quantity) | |
| Other expenses | |
| Net profit | |
| Profit margin (on selling price) | |
| Markup (on cost price) |
How to use this profit calculator
- Enter what one unit costs you — the purchase price plus any per-unit cost like packing.
- Enter what you sell one unit for.
- Enter how many units you sell (or plan to sell).
- Add any other expenses for the whole batch, if you want the net profit rather than the gross profit.
- Read the result: profit per unit, total and net profit, margin and markup.
How profit is calculated
Profit is the money left after the costs of a sale are paid. For a single item it is the simplest sum in business: selling price minus cost price. When you sell many units, each part scales up — the revenue is the selling price times the quantity, and the cost of goods is the cost price times the quantity.
Two percentages come out of the same profit, and this calculator shows both. The margin divides profit by the selling price — it tells you how much of every rupee of sales you keep. The markup divides profit by the cost price — it tells you how much you added on top of your cost. Margin is the safer number for judging a business, because it is measured against the money that actually comes in.
The quantity matters more than most people think. A small profit per unit is fine when the quantity is large — a ₹10 profit on 10,000 units is ₹1,00,000. The reverse is also true: a healthy margin on paper means little if you only sell a handful of units, and it is exactly why the "other expenses" box exists. A batch that looks profitable per unit can turn into a loss once delivery and fees for the whole batch are counted.
Worked example
A trader buys phone cases at ₹450 each and sells them at ₹600 each. In a month he sells 40 pieces, with no other expenses.
- Profit per unit = ₹600 − ₹450 = ₹150
- Total profit = ₹150 × 40 = ₹6,000
- Total revenue = ₹600 × 40 = ₹24,000; total cost of goods = ₹450 × 40 = ₹18,000
- Margin = ₹150 ÷ ₹600 × 100 = 25%
- Markup = ₹150 ÷ ₹450 × 100 = 33.33%
Enter 450, 600 and 40 in the calculator and you will see exactly these figures. Now try adding ₹1,500 of delivery and packing expenses: the net profit falls to ₹4,500, which is the number that actually reaches the bank account.
Profit at different quantities (same ₹450 cost, ₹600 price)
| Quantity sold | Total revenue | Total cost | Total profit |
|---|---|---|---|
| 10 units | ₹6,000 | ₹4,500 | ₹1,500 |
| 40 units | ₹24,000 | ₹18,000 | ₹6,000 |
| 100 units | ₹60,000 | ₹45,000 | ₹15,000 |
| 500 units | ₹3,00,000 | ₹2,25,000 | ₹75,000 |
| 1,000 units | ₹6,00,000 | ₹4,50,000 | ₹1,50,000 |
The margin stays 25% at every quantity, because it only depends on the two prices. What changes with quantity is the total money earned — and whether it covers your fixed expenses for the month.
Frequently asked questions
How is total profit calculated for many units?
First find the profit on one unit: selling price minus cost price. Then multiply by the number of units sold. If you buy a phone case for ₹450, sell it for ₹600 and sell 40 pieces, the profit per unit is ₹150 and the total profit is 150 × 40 = ₹6,000. If you enter other expenses, the calculator subtracts them from this total to give your net profit.
What is the difference between gross profit and net profit?
Gross profit is what is left after paying for the goods themselves: total selling price minus total cost price. Net profit is what remains after every other business expense — rent, delivery, packing, marketplace fees, salaries — is also taken out. This calculator shows both: leave the other-expenses box at zero for gross profit, or enter your extra costs to see the net figure.
Is margin the same as profit percentage?
People use the words loosely, but there are two different percentages. Margin divides profit by the selling price; markup divides profit by the cost price. On a ₹450 cost and ₹600 selling price, the profit of ₹150 is a 25% margin but a 33.33% markup. This calculator shows both so there is no confusion.
What if the selling price is lower than the cost price?
Then you are making a loss, and the calculator shows the profit figures as negative amounts. Selling below cost is sometimes done on purpose — clearing old stock, or a special offer to attract customers — but the loss should be a choice, not an accident. If you see a negative result you did not expect, check the two prices first.
Does this calculator include GST or tax?
No. It works with the prices you enter, exactly as you enter them. If your cost price includes GST that you can claim back as input credit, enter the cost without that GST. If your selling price is the full amount the customer pays including GST, the profit shown will look bigger than your real profit. For tax figures, use the GST calculator or speak to your accountant.
