Direct answer

Dividends and the S&P 500, 1976–2025

A lot, because it compounds. Using annual S&P 500 data from NYU Stern, the index returned about 11.9% a year with dividends reinvested from 1976 to 2025, versus about 9.0% a year from price changes alone. That gap of roughly 2.9 percentage points turned $100 into about $27,933 instead of $7,590, nearly four times as much. Over 1928–2025 the figures are 10.0% versus 6.3% a year. The effect is largest in flat decades: from 1966 to 1975 price alone returned −0.3% a year, while reinvested dividends lifted the total to 3.3%. Dividend yields are lower today, about 1.3% at the end of 2025, so future gaps may be smaller.

  • Total return (dividends reinvested): 11.9% a year
  • Price only: 9.0% a year
  • $100 grew to $27,933 with reinvestment, $7,590 without
  • 1928–2025: 10.0% vs 6.3% a year
  • S&P 500 dividend yield at end-2025: about 1.3%

The S&P 500 number on the news is a price index. It ignores the cash the companies pay out. Over a few months that hardly matters; over a working lifetime it is the difference between a good result and a great one.

What people on X are asking

In May 2026 one investor posted that over the last 50 years the S&P 500 returned about 7.7% a year without dividends reinvested and 11.9% with them, turning $25,000 into about $1 million versus about $6.8 million. In December 2023 another account compared 10 years of S&P 500 total return of +210% with +160% for the price index. And in May 2026 a Swiss investor challenged the often-quoted claim that reinvested dividends make up most long-term returns. Our own calculation, below, confirms the second post and corrects part of the first.

The fact-checked answer

The data. NYU Stern publishes annual S&P 500 total returns (price change plus dividends, assumed reinvested) since 1928, along with year-end index levels. We compared the growth of $100 in the total return series with growth in the index level alone.

S&P 500: price-only vs dividends reinvested

Checking the X numbers. The 11.9% total return over 50 years is right. The price-only figure was closer to 9.0% a year than 7.7%, so $25,000 would have grown to about $1.9 million without reinvestment, not $1 million, and to about $7.0 million with it. The 10-year figures in the 2023 post match our data: about +208% total and +158% price-only for 2014–2023.

Why the gap compounds. Each dividend buys more shares, which pay their own dividends. A 2.9-point annual gap sounds small, but over 50 years it multiplies the ending value by about 3.7 times. The gap is widest when prices go nowhere: in 1966–1975 the index lost value while total return stayed positive, and in 2000–2009 dividends softened a lost decade.

Why future gaps may be smaller. The S&P 500's dividend yield was about 1.3% at the end of 2025, according to the same dataset, against 3% to 5% for much of the 20th century. Companies now return more cash through stock buybacks, which raise the price rather than paying dividends. Total return still captures both, so compare funds on total return, not price.

Taxes and fees. In a taxable account, dividends are taxed in the year paid even if reinvested; IRS Publication 550 explains qualified and ordinary dividends. That drag is why the same strategy grows faster in tax-advantaged accounts. Fund fees also come out of total return, so a 0.03% fund and a 1% fund differ by almost a point a year.

Inputs

Steps

  1. Price-only growth = start × (1 + price growth) ^ years
  2. Total return per year ≈ price growth + yield × (1 − tax rate)
  3. With reinvestment = start × (1 + total return) ^ years
  4. Value of reinvesting = step 3 − step 1

Common mistakes

  • Forgetting that reinvested dividends are taxed in taxable accounts.
  • Chasing high yields instead of total return.
  • Assuming past dividend yields will repeat.
