How to use this DRIP calculator
Enter your initial investment amount and the current share price of your stock, ETF, or fund. Set the current dividend yield (annual dividend ÷ share price) and the expected annual dividend growth rate — how fast you expect the company to increase its dividend each year. Set the expected annual share price growth rate for capital appreciation.
Add any monthly contribution you plan to make regularly. Choose your time horizon in years and toggle dividend reinvestment on or off. The calculator simulates year-by-year growth, showing how shares accumulate, dividends compound, and your portfolio value grows. The year-by-year table lets you track the snowball effect.
The power of dividend reinvestment
Dividend reinvestment creates a compounding loop: dividends buy more shares, which generate more dividends, which buy more shares. Over long periods, this snowball effect dramatically outperforms taking dividends as cash. Historical data from Ned Davis Research shows that reinvested dividends accounted for roughly 84% of the S&P 500's total return from 1960 to 2020.
The math is straightforward but the results are counterintuitive. A $10,000 investment in a stock yielding 3% with 7% price growth and 5% dividend growth turns into very different outcomes over 20 years depending on whether you reinvest. The DRIP version ends up with significantly more shares, higher dividend income, and a larger portfolio — all from the same initial investment.
This calculator lets you toggle reinvestment on and off to see the exact difference. The "DRIP bonus" metric shows the additional portfolio value generated purely from reinvesting dividends.
Dividend growth vs high yield: what matters more
New investors often chase the highest yield, but dividend growth rate is equally important — sometimes more so. A stock yielding 2% but growing dividends at 10%/year will overtake a 5% yielder with 0% growth within 10–12 years. The growing dividend also signals a healthy, expanding business, while stagnant high yields often indicate elevated risk.
The ideal DRIP candidate combines moderate yield (2–4%) with consistent dividend growth (5–10%) and reasonable price appreciation. Companies that have raised dividends for 25+ consecutive years (Dividend Aristocrats) have historically delivered strong total returns with lower volatility than the broad market.
Use this calculator to model different yield vs growth scenarios. Try a 2% yield with 10% growth against a 5% yield with 2% growth over 20 years — the results will demonstrate why growth matters. Compare both against our Compound Interest Calculator for non-dividend investments.
Building passive income with DRIP
Many investors use DRIP as a long-term strategy to build passive income for retirement. The approach is simple: invest consistently, reinvest all dividends during the accumulation phase, and eventually switch to taking dividends as cash when you need income. The year-by-year table in this calculator shows how your annual dividend income grows over time.
A common target is replacing your living expenses with dividend income. If you need $50,000/year, you'd need roughly $1.25 million invested at a 4% yield (or less with a lower yield). DRIP accelerates your path to that target by compounding dividends back into more shares. The "Year N dividend income" metric shows your projected annual passive income at the end of your chosen time horizon.
Frequently Asked Questions
What is a DRIP (Dividend Reinvestment Plan)?
A DRIP automatically uses your dividend payments to purchase additional shares of the same stock or fund instead of paying you cash. Over time, this compounds your returns because you own more shares that generate their own dividends. Many brokerages offer DRIP at no extra cost, and some companies offer direct DRIP programs that may include discounted shares.
How much difference does DRIP really make?
The impact depends on your time horizon, dividend yield, and growth rates. Over 20–30 years, DRIP can add 30–50% or more to your total portfolio value compared to taking dividends as cash. The effect is most dramatic with high-yield stocks, long holding periods, and consistent dividend growth. Even modest dividends compound significantly over decades.
Should I always reinvest dividends?
Not necessarily. DRIP makes the most sense during the accumulation phase when you're building wealth and don't need the income. In retirement or when you need cash flow, taking dividends as income is the whole point. Also consider: reinvesting in the same stock concentrates risk. Some investors prefer to take dividends and redeploy them into underweight positions for better diversification.
Does this calculator account for taxes on dividends?
No. In most countries, dividends are taxable even if reinvested. In the US, qualified dividends are taxed at 0%, 15%, or 20% depending on income. In tax-advantaged accounts (IRA, 401k, ISA, TFSA), dividends grow tax-free. This calculator shows pre-tax returns. Reduce dividend income by your tax rate for a post-tax estimate.
What dividend yield and growth rate should I use?
For broad US market (S&P 500), the current yield is about 1.3–1.5% with 5–7% annual dividend growth historically. Dividend-focused ETFs (like SCHD or VYM) yield 3–4% with lower growth. REITs can yield 4–6%. Individual dividend aristocrats typically yield 2–4% with 5–10% growth. Use realistic numbers based on your actual holdings or target investments.
Privacy and methodology
This calculator runs entirely in your browser — no financial data is sent to any server. It simulates annual compounding: each year, dividends are calculated on current shares at the current yield, reinvested at the current share price, and then price and yield grow by their respective rates. Monthly contributions are simplified as annual purchases at the year's starting price. Results are projections based on constant growth assumptions — actual returns will vary with market conditions.
