Dividend Reinvestment Calculator
The magic of time — see for yourself the powerful compounding effect of dividend reinvestment.
Why does dividend reinvestment matter?
Dividend reinvestment means using the dividends you receive to buy more of the same stock. It's like rolling a snowball: a small snowball (your principal) keeps gathering new snow (dividends → more shares), growing faster and bigger over time. It's one of the most powerful ways to maximize the power of compounding.
For dividend ETFs like SCHD or JEPI, this calculator factors in real-world elements such as taxes and inflation to show how your portfolio grows and when you could reach your financial-freedom goal.

※ Price = last trading day close of each year; dividend = total paid that year. Dividend growth compares only full twelve-month years, and price growth annualizes the whole span from inception to the latest close — the same basis as the ETF detail on the covered-call dashboard.

Historical Data Backtest
Use real historical price and dividend data to answer "what if I had invested back then?" Supports both lump-sum and dollar-cost averaging.

Compare ETF Returns
Run several ETFs side by side over the same period with the same amount. Choose whether to compare price only (dividends excluded) or total return with dividends reinvested.
Every distribution is taxed, then used to buy more of the same ETF (DRIP). This is the real, all-in performance.

💡 Dividend yield & dividend growth, explained in 5 minutes
Confused by the jargon? Just remember one analogy: a dividend stock is like a rental property.
🏦 Dividend yield = "rent as a % of the property price"
It's the share price you paid versus the dividends you receive over a year.
📌 Formula: (annual dividend ÷ price) × 100
📌 Example: a $1,000 stock that pays $35 a year
→ yield = 35 ÷ 1,000 = 3.5%
In other words, "what % of my investment do I get back in cash each year" — much like a bank interest rate.
📈 Dividend growth = "how fast the rent rises each year"
How much more a company pays in dividends each year — the rate of increase.
📌 Example: last year's dividend was $35 and it rises 10% this year?
→ 35 × 10% = $3.5 increase
→ this year = 35 + 3.5 = $38.5 (10% growth)
Good dividend stocks raise the rent (dividend) steadily every year — the core engine of compounding. Even with a low starting yield, a high growth rate snowballs your yield-on-cost over time.
🤔 Why do both matter?
High yield but 0% growth → the same rent every year (a real loss once inflation bites).
Low yield but high growth → small now, but a big dividend in 10 years (e.g. VIG).
Look at both numbers together to spot a truly good dividend stock.
⚠️ Covered-call ETFs (JEPI·JEPQ) are different
Their 8–10% yield comes from option-premium distributions. Unlike steady growers such as SCHD or VIG, those payouts swing far more year to year and vary widely with the manager's options strategy and skill. The calculator auto-fills the real CSV average, but since past figures don't guarantee the future, consider lowering the dividend-growth rate for a more conservative simulation.
How to use this calculator & read the results
What does each input mean?
- Initial Portfolio: The total amount you currently have invested or will start with.
- Monthly Contribution: The amount you keep adding every month.
- Dividend Yield: Annual dividends as a % of the current share price (e.g. SCHD ≈ 3.5%).
- Dividend Growth: How fast the dividend itself grows each year — a key engine of compounding (e.g. SCHD ~10%+/yr on average).
- Price Growth: The annual appreciation of the share price itself, separate from dividends (the S&P 500 has averaged ~7–10%/yr long term).
- Target Real Monthly Dividend: The inflation-adjusted ("real") monthly dividend you want in the future. If you want the equivalent of $2,000/month in today's money, set the target to 2,000.
Nominal vs. real value — which matters?
The results show both "nominal" and "real" values. Understanding the difference is the key to long-term investing.
Nominal Value
The headline number, ignoring inflation — e.g. "my portfolio will be $1M in 30 years."
Real Value
Adjusted for inflation — what that future money is actually worth today. $1M in 30 years might only be worth $500K now. Growing this real value is the real goal.
Frequently Asked Questions
Q. How are dividends taxed?
Tax treatment depends on your country and account type. This calculator applies a single flat dividend tax rate that you can change; the default of 15% reflects the common U.S. withholding rate on qualified dividends. Always confirm the rules in your own jurisdiction.
Q. Does this account for all tax situations?
No. It applies one flat tax rate to dividends and does not model progressive brackets, tax-advantaged accounts, or thresholds that may trigger additional taxes. For your exact situation, consult a tax professional.
Q. How reliable are these results?
These are simulations based on your inputs. No one can predict future prices, yields or inflation precisely, so the results are not a basis for legal or investment decisions — only a powerful planning reference.
Q. Can I use an ETF that isn't in the list?
Yes — type it into the ticker box under the dropdown. All three modes (Future Simulation, Historical Backtest, Compare ETFs) support it. We hold real data for 40+ tickers: dividend growth (SCHD, VIG, DGRO, NOBL, VYM, DIA), high dividend and REITs (HDV, SPYD, SPHD, VNQ), covered call generations 1–4 (QYLD, XYLD, RYLD, JEPI, JEPQ, DIVO, GPIX, GPIQ, SPYI, QQQI, QDTE, XDTE, RDTE, QDTY), YieldMax (TSLY, NVDY, MSTY, CONY, AMZY, APLY, YMAX, YBTC) and index/leveraged funds (SPY, QQQ, IWM, SSO, UPRO, QLD, TQQQ, UWM, URTY).
Q. Is comparing ETFs on price alone good enough?
Between low-yield ETFs it barely matters. With covered-call ETFs it changes the answer completely, because they hand out most of what they earn as distributions, leaving the price flat or drifting down. Take QYLD from December 2013 to September 2026: on price alone it is down about 27%, but with distributions reinvested after tax it is up about 129%. Same fund, same window, opposite conclusion. Compare dividend ETFs on the total-return basis, and use the price basis to see what happened to the principal once the payouts are stripped out.
Q. What period does the ETF comparison use?
It trims the period to the window where every selected ETF existed — a comparison where one fund gets a longer runway isn't a comparison at all. So the most recently launched ETF sets the start date, and removing it lets you compare over a longer stretch. You can also set the dates yourself.
