Calculate stock investment profit, loss, and return percentage
Calculate the exact profit or loss from your stock trades with our free calculator. Whether you're a day trader, swing trader, or long-term investor, understanding your returns is essential for making informed trading decisions. This tool accounts for trade commissions and capital gains taxes to show your real, after-tax return on investment.
Enter your buy and sell prices per share, the number of shares traded, and any commissions or fees you paid. The calculator calculates your total investment cost, revenue, gross profit, and net profit after taxes. It also shows your percentage return and break-even price, helping you evaluate whether a trade was profitable and worth the risk.
The stock profit calculator analyzes your trade from start to finish. First, it calculates your total cost by multiplying the buy price by the number of shares and adding any buy commission. Then, it calculates your total revenue by multiplying the sell price by the number of shares and subtracting any sell commission. The difference between revenue and cost is your gross profit or loss.
Capital gains taxes are applied to profitable trades. In the U.S., long-term capital gains (assets held over one year) are typically taxed at lower rates (0%, 15%, or 20%) depending on your income, while short-term gains (held under one year) are taxed as ordinary income at your marginal tax rate. Enter your applicable rate to see your after-tax profit.
The calculator displays both gross and net returns, showing the impact of taxes on your trade. It also calculates your break-even price – the minimum sell price needed to cover all costs including fees – which is helpful for setting stop-loss levels or determining when to take profits. Your return percentage helps you compare this trade's performance against benchmarks or other investments.
Capital gains tax is a tax on the profit from selling investments like stocks, bonds, or real estate. In the U.S., long-term capital gains (assets held over one year) are taxed at preferential rates of 0%, 15%, or 20% depending on your income. Short-term gains (held under one year) are taxed as ordinary income at your marginal tax rate, which can be significantly higher.
Trade commissions are fees charged by brokers for executing trades. Some brokers charge per-trade commissions, while others offer commission-free trading but may charge for other services. Commissions reduce your overall profit and increase your break-even price. Include both buy and sell commissions for the most accurate profit calculation.
The break-even price is the minimum sell price per share needed to cover all your costs, including the purchase price and any commissions or fees. Below this price, you'll lose money on the trade. Above it, you'll make a profit. Knowing your break-even helps you set realistic stop-loss levels and profit targets for your trades.
ROI is calculated as (Sell Price - Buy Price) / Buy Price × 100% for the gross return. Net return accounts for commissions and taxes. ROI allows you to compare the performance of different investments regardless of their absolute size. Positive ROI indicates profit, while negative ROI indicates a loss on the investment.
The average stock market return is historically around 10% annually before inflation. However, individual stocks can vary widely – some deliver triple-digit returns, while others lose value. What's considered good depends on your investment timeframe, risk tolerance, and benchmarks like the S&P 500. Consistency and managing losses are often more important than chasing high returns.
