In practice, the cash sits. A dividend lands on a Tuesday, life happens, and the redeployment waits for a calmer week that never quite arrives; multiply by four payments a year across a dozen holdings and a &#8220;thoughtful&#8221; investor can end a decade with years of accumulated idle dividend-cash drag, dozens of small delays quietly summed into a real return penalty. The DRIP checkbox is not a convenience feature, it is a commitment device: it removes the daily opportunity to hesitate, which is the same reason automatic transfers beat willpower in <a href=\"\/blog\/dollar-cost-averaging\/\">the monthly investing case<\/a>. The measured behavior gap between investors and their own investments runs to percentage points per year, and almost all of it is timing hesitation, precisely the ingredient the automation deletes from the recipe.<\/p>\n<h2>One year of DRIP, quarter by quarter<\/h2>\n<p>Watch a single year closely and the machine demystifies. Start with 100 shares of a $100 stock paying 1% quarterly. March: $100 arrives and buys one share; you hold 101. June: the dividend is now $101, buying 1.01 shares; you hold 102.01. September: $102.01 buys just over a share; 103.03. December: $103.03 more; you end at 104.06 shares. Nothing dramatic happened in any quarter, and the year still manufactured 4.06 shares from 4 payments, with the fourth payment already 3% bigger than the first. Stretch that ledger across thirty years and the quarterly entries grow from $100 toward $300-plus each, which is the entire snowball, visible one boring line at a time. Investors who print a year of these ledger lines stop needing motivation articles; the arithmetic recruits them permanently.<\/p>\n<h2>Frequently asked questions<\/h2>\n<h3>Do reinvested dividends count as contributions?<\/h3>\n<p>No. Inside an IRA they are treated as growth, not contributions, so they never consume any of your annual contribution limit no matter how large the dividend stream becomes.<\/p>\n<h3>Does DRIP buy at a discount?<\/h3>\n<p>Broker DRIPs buy at the prevailing market price. A few company-run direct plans historically offered small discounts; those are the rare exception now.<\/p>\n<h3>Can I DRIP index funds and ETFs?<\/h3>\n<p>Yes, identically: fund distributions buy more fund shares automatically.<\/p>\n<h3>Is DRIP worth it on small positions?<\/h3>\n<p>Especially there: fractional reinvestment puts even an $11 dividend to work immediately, and small snowballs are still snowballs rolling downhill.<\/p>\n<h3>Do I owe tax when DRIP shares are eventually sold?<\/h3>\n<p>Capital gains tax on the growth beyond your (reinvestment-inflated) cost basis, in taxable accounts. Sheltered accounts follow their own withdrawal rules.<\/p>\n<h3>Does reinvesting change the yield I earn?<\/h3>\n<p>It changes the base: yield applies to an ever-growing share count, which is precisely the snowball.<\/p>\n<h3>Should I DRIP in a taxable account or only in an IRA?<\/h3>\n<p>Both work; the IRA version just skips the yearly tax friction. In taxable accounts, DRIP remains worthwhile, with the phantom-income tax planned for.<\/p>\n<h3>What happens to DRIP during a dividend cut?<\/h3>\n<p>The machine keeps running at the smaller amount: fewer dollars buy fewer shares that quarter. Diversified holdings make any single cut a scratch rather than a wound.<\/p>\n<h3>Does DRIP work with monthly-paying funds?<\/h3>\n<p>Perfectly, and the twelve small reinvestments per year compound marginally faster than four larger ones, the frequency effect in miniature, though the difference is decorative next to yield and time.<\/p>\n<p>Watch your own snowball in the <a href=\"\/finance\/dividend-calculator.html\">dividend calculator<\/a>, see the same engine in its purest form in <a href=\"\/finance\/compound-interest-calculator.html\">the compound interest calculator<\/a>, and the rest of the <a href=\"\/finance\/\">finance tools<\/a> project every phase from first share to income phase.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>DRIP means dividends automatically buy more shares, which pay more dividends.
