Stock Profit/Loss Formulas
Basic Calculations
- Buy Value = Buy Price × Quantity
- Sell Value = Sell Price × Sell Quantity
- Net Profit/Loss = Sell Value – Buy Value – Fees
- Return % = (Net Profit / (Buy Value + Fees)) × 100
Including Fees
Total Investment = Buy Value + Brokerage Fees
Current Value = Sell Value (if all shares sold)
If you sell only part of your holding, the calculator computes profit/loss on the sold portion.
Example
Buy 100 shares at $150 → $15,000
Sell at $175 → $17,500
Fee $10 → Net Profit = $2,490
Return = 16.59%
Partial Sales
The calculator handles different buy and sell quantities. The profit is calculated only on the sold shares.
Understanding Stock Profit & Loss
Investing in stocks can be a powerful way to build wealth, but it’s essential to understand how to calculate your returns. Whether you’re a day trader or a long-term investor, knowing your profit or loss on each trade helps you evaluate performance, manage risk, and make informed decisions. This calculator simplifies that process by accounting for purchase price, quantity, selling price, and transaction fees.
Key Concepts
- Cost Basis: The total amount you paid for the shares, including any commissions or fees.
- Proceeds: The total amount you receive when selling the shares, before fees.
- Net Profit/Loss: Proceeds minus cost basis minus any remaining fees.
- Return Percentage: The profit (or loss) expressed as a percentage of your total investment. This allows you to compare performance across different investments.
Why Fees Matter
Brokerage fees, commissions, and other transaction costs can eat into your profits, especially for frequent traders. Even a small fee of $10 per trade can add up. Our calculator includes a fee field so you can see the true net result after all costs. For example, in the default scenario, a $10 fee reduces the net profit from $2,500 to $2,490 – a small but noticeable effect.
Partial Sales and Average Cost
If you buy shares at different times and prices, your average cost per share changes. This calculator handles a single buy transaction for simplicity. For multiple purchases, you would need to calculate the average cost basis. However, the principle remains: profit = selling price – average cost × number of shares sold, minus fees.
Tax Implications
In many countries, profits from stock sales are subject to capital gains tax. The tax rate may depend on how long you held the shares (short-term vs. long-term). This calculator shows pre-tax returns. Consult a tax professional to understand your specific tax situation.
Tips for Maximizing Returns
- Minimize fees by using low‑cost brokers and limiting unnecessary trades.
- Consider the impact of taxes – holding for more than a year may lower your tax rate.
- Reinvest dividends to benefit from compounding.
- Diversify to reduce risk.
- Regularly review your portfolio and cut losses if a stock no longer meets your investment thesis.
