What is a profit & loss calculator?

A profit and loss calculator compares what something cost against what it sold for, to show whether the sale made money or lost money, both as a rupee amount and as a percentage of the cost price.

How the calculation works

If the selling price is higher than the cost price, the difference is profit. If it’s lower, the difference is a loss. Either way, that difference is then expressed as a percentage of the original cost price, so results are comparable across items of different prices.

Formula

• Profit/Loss amount: Selling price − Cost price
• Profit/Loss %: (Amount ÷ Cost price) × 100

Worked example

An item bought for ₹500 and sold for ₹650 makes a profit of ₹150, which is a 30% profit on cost.

Understanding your result

The percentage shown is always relative to the cost price, not the selling price — this is the standard convention for profit/loss percentage in business and trade.

Factors that affect the result

The result depends only on the two prices entered. It doesn’t include other costs like shipping, marketplace fees or taxes — for a true net profit, subtract those from the selling price first.

Common uses

Resellers and small business owners use this to check margins on individual sales, students use it for commercial maths problems, and shoppers use it to understand markup on resale items.

Important notes

This calculator shows gross profit/loss on a single item only, before accounting for overheads, taxes or other business expenses.
