Stock Profit & Loss (PnL) & ROI% Calculator
Calculate net capital gains, return on investment ROI%, dividend yields, broker commission expenses, and break-even sell prices for stock trades.
Mastering Equity Trade Return and Capital Gain Calculations
Evaluating true equity profitability requires looking beyond simple gross price differences. Professional stock traders and long-term investors must account for order commissions on both entry and exit, accumulated cash dividend payouts, and estimated capital gains tax liabilities to determine their true net profit and annual Return on Investment (ROI%).
The Full Net Equity Profit Equation
Gross Profit = (Selling Price − Purchase Price) × Share Quantity. Net Profit = Gross Profit − Buy Commission − Sell Commission + Total Dividend Payouts. ROI% = (Net Profit ÷ Total Initial Invested Capital) × 100.
How to Use This Stock Profit Calculator
Enter your share buy price, target sell price, share volume, entry/exit transaction fees, dividend payout per share, and local capital gains tax rate. The calculator instantly generates net return, total invested capital, net profit after tax, and required break-even exit prices.
Factoring Dividend Income & Tax Liabilities
For long-term holding strategies, cash dividends earned during ownership significantly boost net return. Conversely, short-term capital gains tax rates can reduce total dollar profit by 15% to 37% depending on tax bracket and holding duration.
Frequently Asked Questions
How do broker fees affect my break-even stock price?
Broker commissions increase your cost basis on purchase and reduce net proceeds on sale, raising your break-even exit price above the original buy price.
Are dividend payouts subject to separate tax rates?
Qualified dividends are typically taxed at long-term capital gains rates (0%, 15%, or 20%), while non-qualified dividends are taxed at ordinary income rates.
How is ROI% calculated on a short stock position?
ROI% on short trades equals (Net Short Profit ÷ Initial Margin Deposit Requirement) × 100.
