Dividend Reinvestment Plans (DRIP)

A DRIP automatically uses dividend payments to purchase additional shares, creating a compounding effect.

How Compounding Amplifies Returns

  • Without DRIP: Growth from price appreciation only
  • With DRIP: Growth from price appreciation PLUS reinvested dividends buying more shares, which themselves generate more dividends

    • Formula

    With DRIP = Investment x (1 + Yield + Growth)^Years

    Without DRIP = Investment x (1 + Growth)^Years

    The difference widens dramatically over longer time periods.

    计算示例

    $10,000 invested in a stock with 3% dividend yield and 5% price growth for 20 years.

    1. Total return with DRIP = 3% + 5% = 8%
    2. With DRIP: $10,000 x (1.08)^20 = $46,610
    3. Without DRIP: $10,000 x (1.05)^20 = $26,533
    4. DRIP advantage = $46,610 - $26,533 = $20,077
    5. Reinvesting dividends nearly doubled the investment outcome
