Example Dividend Reinvestment Calculation
Suppose 100 shares pay $2 per share annually and the share price is $50. The first year creates $200 of dividend cash, enough to buy 4 additional shares in a simplified example.
Over time, reinvested dividends can increase share count, which may increase future dividend income if the dividend per share remains stable.
- Enter starting shares and share price.
- Enter annual dividend per share.
- Enter holding period and optional price growth assumption.
- Review estimated ending shares, portfolio value, income, and reinvested dividends.
