Loading Stock Profit Calculator…
Stock Profit Calculator works out the profit or loss on a stock trade from your buy price, sell price, and quantity, and, importantly, can factor in brokerage and fees for a true net figure alongside the percentage return.
The gross calculation is simple, but the fee element is what makes it honest: brokerage, transaction charges, and taxes are real costs that reduce what you keep, and on small or frequent trades they can turn a modest gross gain into a negligible or negative net one. Looking at net profit avoids a flattering but misleading number.
Read the result two ways. Percentage return lets you compare trades of different sizes fairly (20% on a small position versus 2% on a large one), while absolute profit is the actual cash. Both matter, efficiency and money, and the calculator shows them together.
You can model exit prices before trading to set targets, or review trades afterwards. Everything runs in your browser, keeping your details private, and it's an analysis aid, not financial advice. Pair it with the Average, Dividend Yield, and other ToolsMonk stock calculators.
