How It Works
Dividend reinvestment (DRIP) automatically uses dividend payments to purchase additional shares, creating a compounding effect that significantly boosts long-term returns.
The basic rule:
- Each quarter (or month), dividends earned are used to buy more shares at the current price
- More shares means more dividends next period, which buys even more shares — this is compound growth
- Dividend growth rate increases the yield on your original cost basis over time
- The combination of price appreciation + dividend reinvestment + dividend growth creates triple compounding
Historically, dividend reinvestment has accounted for roughly 40-50% of total stock market returns. A $10,000 investment in the S&P 500 in 1960 would be worth about $350,000 without dividends reinvested, but over $4,000,000 with DRIP — a 10x difference.

Frequently Asked Questions
What is DRIP investing?
DRIP (Dividend Reinvestment Plan) automatically reinvests your dividend payments into additional shares of the same stock or fund. Most brokerages offer DRIP for free. Instead of receiving cash dividends, you receive fractional shares that generate their own dividends.
Is it better to reinvest dividends or take cash?
For long-term growth, reinvesting is almost always better due to compounding. However, taking cash makes sense if: you need the income in retirement, you want to diversify into other investments, or the stock is overvalued and you want to invest the dividends elsewhere.
What is a good dividend yield?
For US stocks, 2-4% is typical for established dividend payers. The S&P 500 average yield is about 1.5%. Yields above 5% may indicate a stock in trouble (price has fallen). Dividend growth rate is often more important than current yield for long-term investors.
Do I pay taxes on reinvested dividends?
Yes, in taxable accounts you owe taxes on dividends even if reinvested. Qualified dividends are taxed at 0%, 15%, or 20% depending on income. In tax-advantaged accounts (401k, IRA, Roth IRA), reinvested dividends grow tax-free or tax-deferred.
What is dividend growth rate?
Dividend growth rate is the annual percentage increase in a company's dividend payment. For example, if a company paid $1.00/share last year and $1.05 this year, the dividend growth rate is 5%. Many quality companies have grown dividends 5-10% annually for decades.
How much can DRIP really add to my returns?
Over 20-30 years, DRIP can roughly double your total return compared to taking dividends as cash. For example, $10,000 invested at 6% price growth + 3% yield for 25 years: without DRIP ~$42,000; with DRIP ~$76,000. The difference grows exponentially with time.
