A Dividend Reinvestment Plan, or DRIP, is one of the most boring and most effective tools in long-term investing. It quietly converts every dividend you receive into more shares of the same stock — without commission and without a decision from you.
What a DRIP Actually Does
Each time a stock pays a dividend, instead of cash hitting your account, the broker uses that cash to buy more shares (including fractional shares). Those new shares pay their own dividends next quarter, which buy more shares, and the cycle continues.
Why It Beats Cash Dividends
Reinvested dividends are the engine of long-term equity returns. Use our DRIP Calculator to compare reinvesting vs taking cash over 20–30 years — the gap is typically tens or hundreds of thousands of dollars on the same initial investment.
How to Turn It On
Every major US broker offers DRIP enrollment as a simple toggle, usually under "Account Settings" or "Dividend Reinvestment". You can enable it for the whole account or per-position.
Tax Considerations
In a taxable account, reinvested dividends are still taxable in the year they were received. The benefit is purely compounding, not tax deferral. In a Roth IRA or 401(k), reinvested dividends compound tax-free.
Cost Basis Complexity
Each reinvested dividend creates a small tax lot at that day's price. After a few years you have dozens of lots. Brokers track them automatically, but if you want to verify or model, our Stock Cost Basis Calculator handles arbitrary lot counts.
Bottom Line
Turn DRIP on, set automatic contributions, then leave the account alone for 20 years. That's the whole strategy.
