Enter your shares, buy and sell prices, commissions, dividends, and tax rate to see your net profit, ROI, annualized return, and break-even price instantly.
A stock profit calculator determines your net gain or loss from a stock trade by factoring in the number of shares, buy and sell prices, commissions, dividends, and capital gains tax. It gives you a complete picture of what you actually take home after all costs — not just the share price difference.
Multiply the number of shares by the sell price, subtract the buy cost (shares × buy price), then subtract any commissions on both sides. Add dividends received during the holding period. If applicable, subtract capital gains tax on the profit. The result is your net profit or loss.
It depends entirely on your timeframe. The S&P 500 averages roughly 10% per year over the long run, so anything consistently above that is strong. For active traders, most professionals target risk-adjusted returns rather than raw ROI — a 5% gain with controlled risk often beats a 20% gain where you could have easily lost 15%.
In the U.S., yes. Profits from selling stocks are subject to capital gains tax. If you held the stock for less than a year, gains are taxed at your ordinary income rate (up to 37%). If you held for over a year, you get the lower long-term rate of 0%, 15%, or 20% depending on your income. Tax-advantaged accounts like IRAs and 401(k)s are exempt from capital gains tax while the money stays in the account.
Commissions eat into your profit on both ends of a trade — once when you buy and once when you sell. On a $5,000 trade, two $4.95 commissions reduce your profit by $9.90. That sounds small, but on frequent trades it compounds. Many brokers now offer zero-commission stock trading, but options, futures, and some international trades still carry fees.
Unrealized profit is what your position is worth on paper — the gain if you sold right now. Realized profit is what you actually lock in when you close the trade. You only owe taxes on realized gains. This calculator shows both: enter your target sell price for unrealized estimates, or the actual sell price for realized numbers.
Simple ROI just tells you the total percentage gain or loss. CAGR annualizes that return so you can compare trades of different lengths. A 20% ROI in 6 months is more impressive than a 20% ROI over 3 years. CAGR makes this clear: the first is roughly 44% annualized, while the second is about 6.3% annualized.
Yes. Dividends are part of your total return. A stock that gains 5% in price but pays 3% in dividends gave you an 8% total return. Ignoring dividends underestimates your actual performance, especially for income-oriented holdings. This calculator includes a dividends field so your total return reflects the full picture.
