Example of Using the Stock Purchase Calculator

Let’s go through a real-world example to understand how the Stock Purchase Calculator works:

Scenario:

Investment Amount: $2,000
Stock Price Per Share: $50
Broker Fee: 1.5%

Step-by-Step Calculation:

Commission Fee: The broker fee is calculated based on the total investment amount.
- Commission Fee = 2,000 × (1.5 / 100) = $30
Amount for Shares: After subtracting the commission fee, the remaining amount is available for purchasing shares.
- Amount for Shares = 2,000 – 30 = $1,970
Number of Shares: Divide the available amount for shares by the stock price.
- Number of Shares = 1,970 ÷ 50 = 39 shares (rounded down to the nearest whole number)
Actual Shares Cost: Multiply the number of shares by the stock price.
- Actual Shares Cost = 39 × 50 = $1,950
Total Cost: Add the commission fee to the actual cost of the shares.
- Total Cost = 1,950 + 30 = $1,980
Cost Per Share (with Fees): Divide the total cost by the number of shares.
- Cost Per Share = 1,980 ÷ 39 = $50.77 per share

Results:

Number of Shares: 39 shares
Commission Fee: $30
Amount for Shares: $1,950
Total Cost: $1,980
Cost Per Share (with Fees): $50.77

This example shows how the commission fee affects the total number of shares you can buy, as well as the overall cost of the transaction.
