Dividend Reinvestment Calculator (DRIP)
Dividend reinvestment — DRIP — is the strategy of automatically buying more shares with every dividend, accelerating compounding. This calculator projects passive dividend income over time using real dividend yields and growth rates from dividend-paying stocks. See exactly when your portfolio starts paying for itself.

How the Dividend Reinvestment Calculator Works
How DRIP compounds
Each period, we apply the dividend yield to the current share count, reinvest the cash into new shares at the projected price, then apply the dividend growth rate. Share count grows, dividends grow, and the eventual passive income compounds against itself.
The DRIP math, formal version
Each dividend period: cash dividend = current shares × dividend per share. Reinvested = cash dividend ÷ current share price → new shares purchased. Total shares grow each cycle. The compounding works two ways: more shares each period pay larger absolute dividends, AND the company's dividend growth rate (typically 3-7% per year for established dividend payers) increases the per-share payout. Over 30 years at modest 3% yield + 5% dividend growth + 6% price appreciation, a $10K starting position can produce annual income larger than the original investment.
Yield on cost vs current yield
Current yield = current annual dividend ÷ current share price. Yield on cost = current annual dividend ÷ your original purchase price. Long-term DRIP investors often see yield on cost climb from a starting 3% to 15-20% as the company raises its dividend over decades, while the current yield stays roughly stable because the share price has also risen alongside the dividend. This is why long-term dividend investing is sometimes called "income that grows by itself" — your cost basis is fixed, the dividend isn't.
Common DRIP pitfalls
Tax leakage in non-shelter accounts: dividends are typically taxed in the year received, even when reinvested. In a UK ISA, US Roth IRA, Australian super, or Canadian TFSA this doesn't apply, but in a regular taxable brokerage account it can take a 15-37% bite annually. Concentration risk: classic DRIP stocks (KO, PG, JNJ, T, VZ) are mostly large-cap consumer staples and utilities — a portfolio of "Dividend Kings" can end up surprisingly undiversified. Yield trap: very high yields (>7-8%) often signal stress, not opportunity — companies that subsequently cut dividends underperform the market sharply.
Frequently Asked Questions
What's a realistic dividend yield?
For broad indices: 1-2% (S&P 500) to 3-4% (UK FTSE 100). Individual dividend stocks: 2-7% common; over 7% often signals stress. Real estate investment trusts (REITs) and utilities tend to yield 4-6%. Yield ≠ total return — high-yielders sometimes underperform on capital gains, so a 6% yielder can underperform a 2% yielder over a decade once price appreciation is included.
Should I reinvest all my dividends or take some as cash?
Depends on horizon and lifestyle. Pre-retirement: reinvest everything; the compounding is the entire point of DRIP. Approaching FIRE: shift the mix gradually, taking some as cash to fund lifestyle while letting growth-tier holdings keep compounding. Already retired: take dividends as income, reinvest only the surplus you don't need. Mechanical "always reinvest" or "always cash" both leave money on the table at different life stages.
What's a Dividend Aristocrat or Dividend King?
Dividend Aristocrats: S&P 500 companies that have raised their dividend every year for 25+ consecutive years. Around 65 companies qualify (KO, JNJ, PG, MMM, MCD, WMT, etc.). Dividend Kings: 50+ years of consecutive raises — much rarer (35-40 companies). The track record signals durable cash flow and shareholder-friendly capital allocation, though it's not a guarantee of future raises.
Are dividends a sign of a healthy company?
Usually, but not always. Mature companies with predictable cash flow that exceeds reinvestment opportunities return capital to shareholders — Coca-Cola, P&G, the major oil companies. Healthy. But sometimes high yields signal stress: a struggling company that hasn't cut yet (Boeing pre-2020), or a value trap where the market expects a future cut. Yield over 7% with negative recent earnings is a red flag, not a buy signal.
Can dividends be cut?
Absolutely. Notable cuts in recent decades: GE (2017, slashed by 50%), Royal Dutch Shell (2020, first cut since WWII), Kraft (2019), most US banks during 2008-09. Even Dividend Aristocrats can lose status — AT&T cut in 2022 after 36 years of consecutive raises. The calculator assumes a constant growth rate; real life has occasional zeros and cuts. Diversifying across 15+ dividend payers materially reduces single-cut impact.
Are dividends taxed?
Yes, in most jurisdictions. US: qualified dividends 0/15/20%, ordinary 10-37%. UK: dividend allowance + bands. Tax-advantaged accounts (Roth IRA, ISA, SIPP) shelter dividends entirely. See our Capital Gains Tax calculator for jurisdiction-specific math.
Does DRIP work better in tax-advantaged accounts?
Materially yes. UK ISA + SIPP, US Roth IRA + 401(k), Australian super, Canadian TFSA + RRSP all shield dividend taxes. Outside those wrappers, dividends are taxed at 0-37% (US) or your dividend allowance + bands (UK) — a meaningful drag on the compound effect over decades. If you have ISA / IRA / TFSA contribution capacity left, dividend stocks are an ideal use of it; you keep the full reinvestment cycle without tax leakage.
What's dividend growth rate, and why does it matter?
Established dividend stocks raise their dividend each year — historically 3-7% for Dividend Aristocrats. That growth means rising income over decades, often beating inflation handily. A 30-year DRIP at modest 5% growth can yield annual income that exceeds the original investment, with no further contributions required. Growth rate matters more than starting yield over long horizons.
