How to Calculate Profit and Loss on a Trade
Calculating the profit or loss on a trade is fundamental to investing. For a long position (buying first, selling later), your profit is the difference between the selling price and the buying price, multiplied by the number of units. For a short position (selling first, buying back later), the calculation is reversed — you profit when the price goes down. Always remember to subtract trading fees to get your true net profit.
Understanding the Formulas
The basic formulas used by this calculator are:
Long P&L = (Exit Price − Entry Price) × Quantity − Fees
Short P&L = (Entry Price − Exit Price) × Quantity − Fees
ROI = Net P&L ÷ (Total Invested + Fees) × 100%
Why Fees Matter
Trading fees can significantly impact your profitability, especially for frequent traders or those with small position sizes. A seemingly profitable trade can turn into a loss once fees are factored in. Always compare the expected profit with the total cost of fees before entering a trade. The break-even exit price shown in the results accounts for fees, telling you the minimum price movement needed to cover your trading costs.

Understanding your profit and loss is the foundation of successful trading. Whether you are trading stocks, cryptocurrencies, forex, or commodities, knowing exactly how much you stand to gain or lose before entering a trade is essential for risk management and long-term profitability.
Many traders make the mistake of only looking at price changes without accounting for fees, position size, or the difference between long and short positions.
