Stock Profit Calculator

Investing in stocks can be a profitable venture if approached wisely. One of the keys to successful trading is understanding the potential profit from stock transactions, including the impact of broker commissions.

Stock Profit Formula

The profit from trading stocks can be calculated using the following formula:

\[ \text{Profit} = [(S \times N) - (C \times S \times N)] - [(P \times N) + (C \times P \times N)] \]

where:

• \(S\) is the selling price per share,
• \(N\) is the number of shares,
• \(C\) is the commission rate (as a decimal),
• \(P\) is the purchase price per share.

Example Calculation

Suppose you purchase 100 shares of a stock at $50 per share, with a commission of 1% both on the purchase and sale. Later, you sell these shares at $60 each. The total profit and return on investment (ROI) would be calculated as follows:

• Total purchase cost: $50 \times 100 + (1\% of $50 \times 100) = $5050
• Total selling revenue: $60 \times 100 - (1\% of $60 \times 100) = $5940
• Profit: $5940 - $5050 = $890
• ROI: \(\frac{$890}{$5050} \times 100\% = 17.62\%\)

Why Calculate Stock Profit?

Calculating stock profit helps investors make informed decisions about when to buy and sell, ensuring they meet their financial goals. It factors in commissions, which can significantly impact overall returns, especially for frequent traders or those trading in large volumes.
