Example Calculation

Suppose you bought 100 shares at $50 per share, sold them at $60 per share, and paid a 2% commission:

  1. Number of shares: 100
  2. Purchase price: $50
  3. Selling price: $60
  4. Commission: 2%

Calculator output:

  • Total Investment: $5,000
  • Total Return: $6,000
  • Commission/Fees: $220
  • Net Profit: $780
  • ROI: 15.6%

This clearly shows how commissions reduce gross profits and allows investors to make better-informed decisions.
