Stock Profit Calculator
Work out the profit or loss on a stock trade, including fees.
What you actually made
The profit on a stock trade is more than the difference between buy and sell prices once fees are counted. This works out the actual profit or loss from your purchase and sale, including trading costs, so you see the real result rather than the headline gain.
Enter your buy and sell prices, quantity and fees to see the profit.
Fees, and the tax that comes after
Two things eat into the headline gain. Trading fees on both the buy and the sell reduce the profit, and on small trades or with a high-cost broker they can turn a modest gain into a loss — which is why frequent small trades are often a poor idea. Beyond fees, a real profit usually attracts tax on the gain, at rates that depend on your location and how long you held the investment, so the amount you keep is less again. This calculates the trading result before tax; what you owe on a gain is a matter for your local tax rules or an accountant. It is a calculation, not investment advice.
Common questions
Do fees really matter to my profit?
Yes — fees on both the buy and sell reduce the gain, and on small trades they can turn a modest profit into a loss.
Does this include tax on the gain?
No — it shows the trading result before tax. Tax on a gain depends on your location and holding period, and is a matter for your tax rules or an accountant.
Is this investment advice?
No — it is a calculation of a trade's result. Investment decisions are for your own judgement or a qualified adviser.
