DRIP stands for dividend reinvestment plan — an arrangement where your cash dividends are automatically used to buy more shares (including fractional shares) of the same stock or ETF, instead of being paid out to you as cash. You can set this up through certain company-sponsored plans or through a brokerage account that offers automatic dividend reinvestment for some or all of your holdings.
Here’s a simple illustration: say you own shares of a stock paying a $1.00 annual dividend per share, and the stock trades at $50. Without DRIP, a $1.00-per-share dividend lands in your account as cash you can spend, withdraw, or invest elsewhere. With DRIP turned on, that same dividend is used to automatically buy about 0.02 additional shares (including a fractional share, if your broker supports it) at the current price. You now own slightly more shares — which means your next dividend payment is calculated on a slightly larger share count, and so on. Nothing about the dividend itself changes; what changes is what happens to it the moment it’s paid.
Why DRIP Compounds Over Time
The effect is easiest to see over a longer stretch. Here’s a simplified, hypothetical comparison of $10,000 invested in a stock with a 3% starting dividend yield and 6% assumed annual price growth, held for 20 years — once with dividends taken as cash, and once with dividends reinvested:
| Dividends Taken as Cash | Dividends Reinvested (DRIP) | |
|---|---|---|
| Starting investment | $10,000 | $10,000 |
| Assumed annual price growth | 6% | 6% |
| Assumed dividend yield | 3% | 3% |
| Approx. stock value after 20 years | ≈ $32,100 | ≈ $56,000* |
| Cash dividends | Received separately | Reinvested |
*This simplified illustration assumes a constant 6% annual price increase and a 3% dividend yield, with dividends reinvested annually. It ignores taxes, fees, changes in dividend rates, and market fluctuations. The point isn’t the exact numbers; it’s the mechanism: reinvested dividends buy more shares, those shares generate their own dividends, and the gap between the two paths widens the longer the money stays invested.

Official Source and Assumptions
Reinvested dividends are still taxable income in the year they’re paid, even though you never touched the cash — the IRS treats a reinvested dividend the same as one paid out to you (see IRS Topic No. 404, Dividends). Whether a specific stock or fund offers a company-run DRIP, and whether your broker offers commission-free automatic reinvestment with fractional shares, varies by company and brokerage — check your account settings or the company’s investor relations page to confirm. The example above assumes a constant yield and constant price growth for simplicity; real dividend payments and share prices fluctuate and are never guaranteed.
FAQ
Do I owe taxes on dividends I never actually received as cash?
Yes. Whether you take a dividend as cash or have it automatically reinvested, it’s taxable in the year it’s paid (in a standard taxable brokerage account — this doesn’t apply the same way inside a tax-advantaged account like a Roth or Traditional IRA). Your broker will report it on Form 1099-DIV either way.
Can I turn DRIP on for some holdings and not others?
Usually, yes. Most brokerages let you enable automatic dividend reinvestment on a position-by-position basis, so you can reinvest dividends from your long-term holdings while taking dividends as cash from positions you’re using for current income.
Does DRIP affect my cost basis?
Yes. Each reinvested dividend generally creates a new purchase of shares or fractional shares, which adds to your cost basis. Keeping accurate records matters when you eventually sell — see What Is Average Cost Basis? for how repeated purchases at different prices combine into one number.
