What is a DRIP (Dividend Reinvestment Plan)?

A DRIP, or Dividend Reinvestment Plan, is a program that automatically uses dividend payments to purchase additional shares of the same stock or fund instead of paying the dividend as cash. Over time, this creates a compounding effect: more shares earn more dividends, which buy even more shares — often called the "dividend snowball." Most brokerages offer automatic dividend reinvestment at no charge.

How does reinvesting dividends grow your portfolio?

When you reinvest dividends, you use each payment to buy more shares at the current price. Those additional shares then generate their own dividends in the next period, which buy even more shares. This compounding effect — earning returns on your reinvested returns — is what separates DRIP from simply collecting cash dividends. Over 20–30 years, reinvestment can more than double the outcome compared to taking dividends as cash, depending on the yield and dividend growth rate.

What is yield on cost and why does it matter?

Yield on cost is your current annual dividend income divided by your original cost basis (total invested capital). For example, if you invested $10,000 and your dividend income has grown to $900 per year, your yield on cost is 9% — even if the stock's current market yield is only 3.5%. Yield on cost grows over time because dividend reinvestment accumulates more shares and dividend growth increases the payout per share. It is one of the most compelling long-term metrics for dividend investors.

Is it better to reinvest dividends (DRIP) or take them as cash?

Reinvesting dividends almost always produces higher total wealth over long time horizons when the stock or fund continues to grow. However, taking cash makes more sense if: (1) you need the income for living expenses, (2) you can deploy the cash into a higher-returning investment, or (3) you are in a taxable account and want to avoid the tax drag of reinvesting. The FinanceWonk DRIP calculator lets you compare both paths side by side using the Cash Dividend Return Rate input to model where else your dividends could be invested.

Does DRIP work in a bear market?

Yes — bear markets can actually make DRIP more powerful. When share prices fall, each reinvested dividend buys more shares at a lower price, increasing your share count faster. When prices eventually recover, you benefit from that larger share base. This is why the DRIP advantage over taking cash often increases in bear scenarios compared to bull scenarios. The bear/base/bull scenario comparison in this calculator illustrates this clearly.

What dividend growth rate should I use?

For large, established companies with a history of dividend increases, 3–5% annual dividend growth is a reasonable conservative estimate. "Dividend Aristocrats" — S&P 500 companies that have raised dividends for at least 25 consecutive years — have averaged around 6–8% annual dividend growth historically. REITs and utilities often have lower growth rates (1–3%) but higher starting yields. Set the dividend growth rate to 0% to model completely flat dividends.

What is a DRIP and how does dividend reinvestment work?

A DRIP (Dividend Reinvestment Plan) automatically uses your dividend payments to buy more shares of the same stock or fund instead of paying you cash. Over time, those additional shares generate their own dividends, creating a compounding cycle. Many brokerages offer DRIPs for free with no commission on reinvested shares.

Is it better to reinvest dividends or take the cash?

For long-term investors, reinvesting dividends typically produces significantly higher total returns due to compounding. Historically, reinvested dividends have accounted for roughly 40% of the S&P 500's total return over multi-decade periods. However, if you need current income — such as in retirement — taking dividends as cash may be more appropriate.

How much difference does dividend reinvestment make over time?

The impact is substantial over long periods. For example, $10,000 invested in an S&P 500 index fund 30 years ago would be worth roughly 2–3 times more with dividends reinvested compared to taking dividends as cash. The difference grows with time because each reinvested dividend buys shares that produce future dividends of their own.
