DRIP automatically uses your dividend payments to buy more shares of the same stock — including fractional shares — instead of paying you cash. Most major brokers offer it free of commission. Over decades, this compounding effect dramatically increases total returns vs taking dividends as cash.

Each reinvested dividend buys more shares, which then earn their own dividends, which buy more shares. This 'dividends on dividends' effect compounds exponentially. A $10,000 investment in S&P 500 from 1980 to 2020 grew to ~$95,000 with price appreciation alone — but to ~$760,000 with reinvested dividends.

Yes — even though you don't receive cash, reinvested dividends are taxable in the year they're paid. The good news: each reinvestment increases your cost basis, so when you eventually sell, your taxable gain is reduced. Hold dividend stocks in tax-advantaged accounts (Roth IRA, ISA) to avoid the annual tax drag entirely.

Reinvest when: (a) you don't need the income, (b) the stock is still high quality, (c) you're in accumulation phase. Take cash when: (a) you need retirement income, (b) the company is fundamentally weakening, (c) you want to redeploy elsewhere. The calculator lets you compare both scenarios side-by-side.

Companies that consistently raise their dividends (Dividend Aristocrats — 25+ years of increases) compound your income stream alongside the share count. KO has raised dividends every year since 1963; reinvesting those raises produces extraordinary long-term yields on cost (often 15–30% by year 30). Look for dividend growth, not just current yield.

You can specify recurring contributions (monthly, quarterly, annually) on top of the reinvested dividends. Each new contribution joins the compounding base — buying shares at the current price and starting to earn its own dividends. Adding modest monthly contributions ($100–500) on top of DRIP can dramatically accelerate the wealth-building timeline.
