S&P 500 is included only as a total-portfolio-value reference — it isn't the most meaningful benchmark for income-focused strategies. The 10% baseline reflects the index's long-term nominal total return (price + dividends), a reference rather than a forecast.
What this calculator does
A compound dividend calculator stretches the math out over decades and shows where compounding actually does its work. The first ten years look unimpressive; the next ten are noticeably bigger; years 20 through 30 are where reinvested dividends, dividend growth, and share-price appreciation all stack and outpace simple year-over-year intuition. The table makes that curve readable: you can see exactly which year your annual dividend crosses the milestones that matter to you.
How to use it
Defaults assume a 30-year horizon with DRIP on, which is the right framing for "what would this turn into?" If you're modeling a real account, start from what you've already invested and the current share price. Use a realistic dividend growth rate — broadly diversified dividend ETFs have historically grown payouts around 6-8% per year, though individual stocks vary widely. Share price growth lower than dividend growth is unusual long-term but happens in flat-market decades.
Frequently asked questions
Why does compounding seem slow for the first ten years?
Compounding is exponential, but exponentials start slow. With a 7% growth rate, money roughly doubles every decade; the first doubling looks tiny in dollar terms because the base is small, while the third doubling looks dramatic because the base is already large. The table makes this visible — compare year 10 income to year 20, then year 20 to year 30, and the acceleration is hard to miss.
Does this calculator account for share price changes over time?
Yes. Annual share price growth compounds the price independently from the dividend, and DRIP buys shares at the average price for each year. If you set share price growth to 0%, you're modeling a flat-price scenario where every dividend buys progressively more shares than it would in a rising market — same income, more share-count growth.
What happens if I lower the horizon to 10 years?
You see the early-compounding portion of the curve without the tail. That's actually useful for setting near-term expectations or for comparing two investments side by side without long-horizon optimism distorting the comparison. Move the years slider down to 10 or 15 to see how different the picture looks at shorter horizons.
