Example:
- Buying Price = $50 per share

Formula:
Dividend Yield = Annual Dividend per Share / Stock Price per Share * 100

Dividend Yield = 2 / 40 * 100 = 5%
3. Return on Investment (ROI) Calculator

Formula:
ROI = Current Value – Initial Investment / Initial Investment * 100
Example:

ROI = 7,000 – 5,000 / 5,000 * 100 = 40\%
