Profit/Loss Calculator

Profit and loss formulas

Profit or loss is the difference between what you paid and what you received. The core formula is profit = selling price - cost basis. If you buy something for $200 and sell it for $260, the profit is $60.

Percentage return uses the starting cost: return % = profit / cost basis × 100. A $60 profit on a $200 cost is a 30% gain. If the sale price is $170, the loss is $30 and the return is -15%.

Fees and real results

Trading fees, marketplace fees, shipping, taxes, spreads, and currency conversion can change the real outcome. Add fees to the cost side or subtract them from the sale side before using the result for a decision.

When to use it

This calculator is useful for quick checks on stock trades, crypto trades, resale items, small business purchases, or project margins. It is an estimate tool, not tax, accounting, or investment advice.
