Profit/Loss Calculator is a free online tool on ToolsMonk with a single focus: calculate trade p/l with scenario analysis. Whether you're a professional, student, or casual user, it provides instant, accurate results right in your browser without requiring any software installation or account creation.
All processing runs locally in your browser, so your files and data never leave your device. The interface adapts to any modern browser and screen size, so the Business Tools workflow you rely on at a desk is the same one you get on a tablet or phone.
Profit/Loss Calculator works out the gain or loss on a stock trade from your buy price, sell price, and quantity, reporting both the absolute amount and the percentage return so you can see the result two ways at once.
The formulas are simple but worth being precise about: profit is the price difference times quantity, and percentage return is the price difference over the buy price. Having both matters, absolute profit is the cash, while percentage return measures how hard your capital worked, which is the fair way to compare trades of different sizes.
One thing to remember is that the figure is pre-cost. Brokerage, transaction charges, and taxes on gains reduce your real take-home and vary by broker and country, so subtract them for an accurate net result. The output is an analysis aid, not financial advice.
You can model different exit prices before trading to set realistic targets, or review completed trades for your records. Everything runs in your browser, so your trade details stay private. Pair it with the Stock Average and other ToolsMonk finance calculators for fuller analysis.
Always subtract brokerage and taxes from the result for your real net profit
Judge trades by percentage return, not just rupees/dollars, so you can compare different position sizes fairly
Model a target and a stop-loss sell price in advance to plan the trade, not just review it after
