What is DRIP (Dividend Reinvestment) Calculator?
The DRIP Calculator projects how your dividend reinvestment plan compounds over time. By modeling the reinvestment of dividends into additional shares alongside stock price appreciation, it shows the powerful effect of compounding on your portfolio's growth.
Steps:
- Enter your initial number of shares and current stock price.
- Set the annual dividend yield and expected stock growth rate.
- Choose your investment period and reinvestment frequency.
- View your projected portfolio growth year by year.
Formula
Each Period: Dividend Income = Shares × Price × (Yield / Periods)
New Shares = Dividend Income / Current Price
Shares += New Shares
Price grows by (1 + Growth Rate / Periods) each period
