Why reinvesting dividends compounds so hard
A DRIP — Dividend Reinvestment Plan — takes the dividends your holdings pay and automatically buys more shares, instead of handing you the cash. That small mechanical choice sets off two compounding engines at once: each reinvested dividend buys shares that pay their own dividends, and if the company keeps raising its payout, the dividend on every share grows too.
The result is a curve that bends upward. In the early years the difference between reinvesting and spending looks small. But because the share count keeps growing, the gap widens every year — and over two or three decades, reinvested dividends often account for the majority of an investor’s total return. The calculator above makes that gap explicit.
This is the essence of the dividend snowball. For a fuller model — with monthly contributions, tax and inflation — use the compound interest calculator.
Frequently asked questions
What is a DRIP (Dividend Reinvestment Plan)?
A DRIP automatically uses the dividends a stock or fund pays to buy more shares of that same investment, instead of paying the cash to you. Over time this compounds: more shares pay more dividends, which buy still more shares. Many brokers and companies offer it for free, often including fractional shares.
How much difference does reinvesting dividends make?
A large one over long periods. Reinvested dividends are responsible for a substantial share of the stock market's total long-run return. Because each reinvestment buys shares that then pay their own dividends, the effect accelerates the longer you leave it — which is why the gap between reinvesting and spending dividends widens dramatically over decades.
Is it better to reinvest dividends or take the cash?
During your accumulation years, reinvesting almost always builds more wealth because it maximises compounding. Once you need the income — for example in retirement — taking the cash makes sense. Many investors reinvest for decades and switch to cash only when they start drawing on the portfolio.
Do I pay tax on reinvested dividends?
In most jurisdictions, yes — reinvested dividends are generally taxable in the year they are paid, just like cash dividends, even though you never received the cash. Tax-advantaged accounts can change this. This calculator shows the pre-tax effect; check the rules where you live.
