About Dividend Reinvestment Calculator (DRIP)
DRIP compounding runs two engines at once: the dividend per share grows (management raises the payout) AND your share count grows (each payment buys more shares). At the defaults — 3% yield, 6% dividend growth, 6% price growth, 20 years — $10,000 becomes roughly $56,000 reinvested versus about $43,000 taking the cash. The gap is pure mechanics: cash dividends sit still; reinvested ones join the workforce. The quietly spectacular output is the final-year income: the defaults end with the position paying ~$1,500 a year on its own — a 15% 'yield on cost' against your original $10,000, up from 3%. Long-horizon dividend-growth investors aren't chasing today's yield; they're building tomorrow's, and this is the arithmetic of how a boring 3% payer becomes a personal income machine by year 20. Honest footnotes: reinvesting at ever-higher prices (the model reinvests at each year's new price) slightly dampens the snowball in bull markets and feeds it in flat ones — DRIP actually loves sideways decades. Taxable accounts owe tax on dividends the year paid even when reinvested, so the full two-engine effect belongs in tax-sheltered accounts; and a dividend CUT hits both engines simultaneously, which is why payout sustainability matters more than headline yield.

Frequently asked questions
Should I reinvest dividends automatically or take cash?+
Accumulating with a decade-plus horizon: reinvest — the share-count engine is the half of compounding most investors leave off. Living off the portfolio: take cash; that's what the stream is for. Middle path many use: stop auto-DRIP within 5 years of needing income and direct dividends to the best current opportunity instead of mechanically back into the payer — automatic DRIP buys regardless of valuation.
Does DRIP work better in rising or falling markets?+
Falling and flat markets are secretly DRIP's best friend — each payment buys MORE shares at lower prices, loading the spring for recovery. A stock that pays steadily through a sideways decade hands DRIP investors dramatically more shares than a straight-up climber. The model shows this: cut the price-growth input to 0–2% and watch the reinvested-vs-cash gap widen relative to the final value.
What's yield on cost and why do DRIP investors track it?+
Final-year income divided by your ORIGINAL investment. Defaults: ~5.5% by year 20 versus the 3% you started with — dividend growth plus share accumulation raised your personal yield without one new dollar. It's motivating, but don't let it block selling decisions: capital today should earn the best CURRENT return available; yield on cost is a rear-view metric, not a valuation.
Are reinvested dividends taxed?+
In taxable accounts, yes — dividends are taxable income the year they're paid whether you take cash or shares, so DRIP can create tax bills with no cash to pay them. Each reinvestment also creates a tiny tax lot whose cost basis you must track for eventual sale (brokers do this now, but old DRIP plans are a paperwork legend). Inside 401(k)s/IRAs and equivalents, none of this applies — the full snowball rolls untaxed.
