Glossary & Formulas
Key Terms
- Starting principal
- The initial amount of money invested to purchase shares.
- Dividend yield & growth
- The yield is the expected annual percentage payout based on the share price. The growth is the expected annual percentage increase of that payout.
- DRIP (Dividend Reinvestment Plan)
- The process of automatically using cash dividends received to purchase additional shares of the underlying asset.
- Yield on cost
- The annual dividend income divided by the total original principal and contributions invested.
- Share price growth
- The estimated annual appreciation of the stock's underlying price, driving capital gains independent of dividends.
Formula Used
When DRIP is enabled, dividends generate a compounding effect by acquiring more shares. The period-over-period logic is:
Gross Div = Shares × (Yield / Payments)
Net Div = Gross Div × (1 - Tax Rate)
New Shares = Net Div / Current Price
- Shares: The current number of shares owned.
- Yield: The annual dividend yield rate.
- Tax Rate: Applicable dividend tax percentage.
- Payments: Dividend frequency per year (e.g. 4 for quarterly).
- Current Price: The modeled share price that appreciates yearly by the growth rate.
