What is a DRIP (Dividend Reinvestment Plan)?
A Dividend Reinvestment Plan (DRIP) is an automated financial arrangement that directs your brokerage to immediately use cash dividend distributions to purchase additional whole or fractional shares of the dividend-paying entity, typically with zero transaction commissions.
The Mathematical Impact of DRIP Compounding
When you reinvest dividends instead of taking cash payouts, two compounding forces work in tandem:
- Share Count Expansion: Every distribution increases your total share ownership without out-of-pocket capital injections.
- Increased Future Dividends: The next dividend payout is calculated on a larger base of shares, creating an exponential "snowball effect."
Over a 20-year horizon, historical S&P 500 data demonstrates that total returns with reinvested dividends outperform price-appreciation-only returns by more than 200%. Check our DGI Strategy Guide.
Frequently Asked Questions
Do I have to pay taxes on dividends that are automatically reinvested via DRIP?
Yes. The IRS treats reinvested dividends as cash income received during that tax year, even though you never transferred the money into your checking account.
Does DRIP adjust my cost basis for capital gains taxes?
Yes. Each DRIP share purchase creates a new tax lot with its own cost basis equal to the market price paid at the time of reinvestment.
