How Much Will Your Dividend Portfolio Grow?
Model the compounding power of reinvesting dividends alongside regular contributions. Set your yield, price growth, and time horizon.
Reinvested dividends account for nearly half of the stock market's long-run total return — the snowball is the strategy.

Why reinvesting beats taking the cash
Why reinvesting dividends matters
Studies show that reinvested dividends account for 40–50% of the S&P 500's total long-run return. Over a 30-year period, an investor who reinvests dividends ends up with roughly twice the portfolio value of one who takes dividends as cash.
The best stocks for DRIP investing
Dividend Aristocrats (companies that have raised dividends for 25+ consecutive years) are popular DRIP choices: Johnson & Johnson, Coca-Cola, Procter & Gamble. ETFs like SCHD automate diversified dividend reinvestment.
Tax considerations
Reinvested dividends are still taxable in the year received, even if you don't take the cash. In a tax-advantaged account like a Roth IRA or 401(k), DRIP investing is especially powerful because growth is tax-free.
How the DRIP Calculator Works
Formula
Each month (dividends reinvested):
dividend = value × (yield / 12)
value = value × (1 + priceGrowth/12) + dividend + contribution
DRIP advantage = reinvested value − value if dividends taken as cash
Today's $ = value ÷ (1 + inflation)^years (live FRED CPI)Set your starting investment
The lump sum already in dividend-paying stocks or ETFs.
Add a monthly contribution
Optional regular buying on top — it compounds alongside the dividends.
Enter yield and price growth separately
Dividend yield drives the reinvestment snowball; price growth appreciates your shares.
Choose your horizon
DRIP rewards time — the snowball accelerates in the later years.
Compare reinvest vs cash
See the dollars you'd forfeit by spending dividends, plus the value in today's money.
Rather than lumping dividends and price growth into one rate, this calculator simulates them separately month by month. Dividends are computed on your current balance and reinvested to buy more shares — which then pay their own dividends. With the default inputs ($10,000 + $200/month, 4% yield, 5% price growth, 20 years) the portfolio reaches about $194,000, of which roughly $60,000 is reinvested dividends.
The defining DRIP number is the comparison: reinvesting finishes at ~$194,000, while taking those same dividends as uninvested cash would leave about $150,000 — a ~$43,000 advantage purely from reinvestment. The calculator also deflates the result by the live FRED CPI rate, so a $194,000 portfolio in 20 years is shown as roughly $103,000 in today's buying power.
