How it works
A stock profit calculator estimates whether a single trade ends in a gain or a loss. It uses the number of shares, buy price, sell price, and any costs or dividends you enter to summarize the trade outcome in dollars and percentage terms.
The calculator starts with the gross purchase amount and adds buy-side fees to build the cost basis. It then subtracts sell-side fees from the gross sale amount to estimate net sale proceeds. The difference between those two figures is the net profit or loss.
Cost basis is the total amount you put into the trade before it is sold. In this calculator, that means the share purchase amount plus any buy-side fees or commissions. A higher cost basis means the trade needs a higher sale price to break even.
Fees matter on both sides of the trade. Buy-side fees increase the cost basis, while sell-side fees reduce what you actually receive when closing the position. Even small commissions can noticeably shrink a modest gain or deepen a loss.
Dividends do not change the sale proceeds, but they can improve the overall return from holding the stock. That is why the calculator shows net profit or loss first, then separately adds dividends to the total return view.
Return percentage shows the net profit or loss relative to the total cost basis. If you add dates, the calculator also shows an informational short-term or long-term label based on the holding period. That label is for general reference only and is not tax advice or a capital gains tax calculation.
