Dividend Reinvestment (DRIP) Calculator
Calculate the compound growth of dividend reinvestment over time.
See how DRIP turns dividends into additional shares and accelerates wealth building.
Dividend reinvestment (DRIP) is one of the most powerful wealth-building strategies available to ordinary investors. Instead of receiving dividend payments as cash, you automatically use them to purchase additional shares — creating a compounding cycle that accelerates over time.
Basic annual income formula:
Annual Dividends = Shares × Annual Dividend per Share
Yield formula:
Dividend Yield = (Annual Dividend per Share / Share Price) × 100
Compound growth with DRIP (annual compounding):
Future Value = Initial Investment × (1 + Dividend Yield)^Years
More precise quarterly DRIP formula:
Future Value = P × (1 + r/4)^(4 × t)
Where:
- P = Initial investment (principal)
- r = Annual dividend yield (as a decimal)
- t = Years invested
- 4 = Quarterly compounding frequency
Worked example: You invest $20,000 in a dividend stock with a 4% annual yield. With DRIP over 25 years (assuming stable yield and price):
- Year 5: ~$24,333
- Year 10: ~$29,605
- Year 20: ~$43,822
- Year 25: ~$53,310
Without DRIP (cash dividends only): $20,000 + ($800 × 25) = $40,000 With DRIP: $53,310 — over $13,000 more from compounding alone.
Why DRIP works so well:
- Compounding effect — each reinvested share earns future dividends, building momentum
- Dollar-cost averaging — you buy shares at various prices over time, smoothing out volatility
- Zero-commission reinvestment — most brokerages and company DRIPs charge no transaction fees
- Fractional shares — dividends buy partial shares, so no cash sits idle
Reference yields by sector (approximate):
- Utilities: 3–5%
- REITs: 4–7%
- Blue-chip stocks: 1–3%
- High-yield stocks: 6–10% (higher risk)
The longer the time horizon, the more dramatic the compounding effect becomes. A 4% yield reinvested over 30 years effectively doubles the total return compared to taking dividends as cash.
