DRIP stands for Dividend Reinvestment Plan. It's one setting in your brokerage account, and it decides what happens to your dividends — the cash a fund pays you for holding it. Leave the setting off, and those dividends land in your account as cash. Switch it on, and they automatically buy more shares for you.
That sounds like a small choice. Run it for thirty years and it can roughly double what you end up with.
This article shows you exactly that — the same money invested both ways — then explains why the gap gets so wide, and when leaving DRIP off is actually the smarter move.
When you own a dividend-paying fund, it pays you a little cash on a schedule — usually every three months. That payment is a dividend.
DRIP decides where that cash goes:
DRIP off — the dividend shows up as cash. You can spend it, save it, or invest it yourself later.
DRIP on — the dividend immediately buys more shares of the same fund, automatically, for free at most brokerages.
Here's the part that matters. Those new shares pay their own dividends next time. Which buy more shares. Which pay more dividends. The cycle feeds itself in the background. (For a fuller walk-through of how each dividend is calculated month by month, see .)
That loop is the whole story. Let's put real numbers on it.
Take one example and run it twice — once with DRIP off, once with DRIP on, everything else identical.
You start with $10,000, add $500 a month, and hold a fund that pays a 3.5% dividend yield (it pays 3.5% of its price each year), with that dividend growing 7% a year and the share price rising 6% a year. You run it for thirty years inside a tax-free account like a Roth IRA. Over those thirty years you put in about $190,000 of your own money, either way.
Same money in. Here's where it lands.
| DRIP off | DRIP on | |
|---|---|---|
| Year 10 | $99,000 | $124,000 |
| Year 20 | $259,000 | $429,000 |
| Year 30 | $545,000 | $1,280,000 |
By year thirty, reinvesting the dividends added roughly $735,000 — on top of the same $190,000 you put in either way. More than double the ending balance, from one toggle.
Look at how the gap grows. At year 10 it's about $25,000. At year 20, $170,000. At year 30, $735,000. The gap doesn't grow steadily — it starts small and then runs away from itself. That's compounding: the longer it runs, the faster the distance widens.
One honest caveat before you get too excited. This gap is as large as it is partly because of the assumptions. A 3.5% yield, a full thirty years, and zero tax all make reinvesting look its best. In a regular taxable account, dividends get taxed before they can reinvest, which shrinks the effect (more on that in how dividends are taxed). A lower yield shrinks it too. So the lesson isn't "DRIP always doubles your money." It's that reinvesting did the heavy lifting here — and the things that make that lift big or small are worth understanding before you count on it.
Same money went in both times. The only difference is what happened to the dividends. So where did an extra $735,000 come from?
Shares.
With DRIP off, you finish with about 948 shares. With DRIP on, you finish with 2,230 shares. Both started at 100. The difference — roughly 1,280 extra shares — is built entirely from dividends buying more shares, year after year, each new share then earning dividends of its own.
Here's the cleanest way to see it. The dividend per share grew exactly the same in both cases — from about $3.50 a share at the start to roughly $27 a share by year thirty. Reinvesting didn't change the dividend per share at all. It changed how many shares you owned to collect that dividend on.
That's why the early years barely differ and the late years blow apart. Reinvested dividends in year one buy you a handful of extra shares. By year thirty, those shares have been buying more shares, which bought more shares, for three decades.
Reinvesting pays off hardest under three conditions:
A long time horizon. The loop needs years to build. Look at year one in the example: $16,800 with DRIP off versus $17,100 with it on. Almost nothing. The magic is entirely in the back half.
A higher dividend yield. More dividend each round means more cash buying more shares. A fund that pays very little gives reinvestment less to work with.
A tax-free or tax-deferred account. In a Roth IRA or similar, no tax gets skimmed off your dividends before they reinvest, so the full amount compounds. (Here's how the tax side works.)
Put those together — young, investing through a Roth, decades from needing the money — and DRIP is doing more for you than almost any other single setting in your account.
Turning DRIP off is not a mistake. Sometimes it's the entire point.
If you'll need the money soon. Over a few years, the reinvestment loop never really gets going. The two paths look nearly identical early on, so DRIP isn't the lever that matters on a short timeline.
If you need the dividends to live on. This is the big one. Picture someone retired, using their dividends as income. Taking that cash is exactly what they built the portfolio for. In the example, the DRIP-off version still grows to $545,000 and pays about $25,300 a year in cash you can actually spend. The DRIP-on version ends bigger, but every dividend got reinvested — none of it reached your pocket.
So the real difference is the job you're asking the money to do:
DRIP on is for building. You're growing the pile and don't need the cash yet.
DRIP off is for harvesting. The portfolio is paying for your life, and you want the income in hand.
Neither is right or wrong. They're different stages. (Choosing between a bigger pile later and steadier income now is its own decision — it's the heart of dividend yield vs. dividend growth.)
Flip DRIP on and off and watch the year-30 number jump. Then make it realistic for you — lower the yield, shorten the timeline, switch on a tax rate — and see how much of that gap survives.
DRIP is a single setting, free to turn on, and on a long enough timeline it does an enormous amount of work in the background. It is not free money, and it is not always the right choice — if you need the cash, take it. But if you're building for the long run and don't need the dividends yet, leaving DRIP on may be the easiest high-impact decision you'll make.
What does DRIP stand for?
Dividend Reinvestment Plan. It automatically uses your dividends to buy more shares of the same fund, instead of paying them to you as cash.
Does reinvesting cost anything?
At most major brokerages, no — DRIP is free and buys fractional shares, so every cent of the dividend gets put to work.
Do I still owe tax on dividends I reinvested?
In a regular taxable account, yes — this catches people out. Even though the cash never reached your pocket, reinvested dividends usually count as taxable income the year they're paid. In a Roth IRA or similar account, they aren't taxed that way. (More on dividend taxes here. This is general information, not tax advice.)
Can I turn DRIP on and off whenever I want?
Yes. It's a setting you can change at any time — many people reinvest while they're building, then switch it off later when they want the income.
Is DRIP automatic, or do I have to do it manually?
Once you switch it on, it's automatic. Every dividend reinvests on its own with no action from you.
Does DRIP work for ETFs, not just stocks?
Yes. It works for any dividend-paying investment, including the ETFs most beginners start with.
