If you invested $100 in the S&P 500 in 1936
$100 invested in the S&P 500 at the start of 1936 — with dividends reinvested and held through end of 2024 — would be worth $889,415 nominal, or $38,813 in 1936 purchasing power. That's 10.76% annualized nominal return, or 6.93% real return, over 89 years.
How this was computed
We take the S&P 500 total return series (price change plus dividends reinvested at year-end) from start of 1936 through end of 2024 — a 89-year window — and apply the actual year-by-year return to a starting balance of $100. The nominal figure of $889,415 reflects the market value in 2024 dollars. The real figure of $38,813 strips out cumulative CPI-U inflation over the same window, expressing the end value in terms of 1936 purchasing power.
Total multiplier: 8894.15× nominal (real: 388.13×). Cumulative CPI-U inflation over the window: 22.92× — meaning one 1936 dollar buys 0.04 2024 dollars of goods.
What this scenario captures
Every rolling multi-decade window contains its own crisis and recovery. The 89-year window starting 1936 includes the market events of that era — bull runs, drawdowns, monetary regime changes, and inflation cycles — all baked into the compounded number. Long-run S&P 500 real return since 1928 has averaged roughly 6.9%; the 6.93% realized in this specific window exceeded that average.
What the calculation excludes
- ETF or mutual fund expense ratios (VOO 0.03%, SPY 0.09%, IVV 0.03%)
- Taxes on dividends (typically 15-20% qualified rate) — inside a Roth IRA or taxable-account brokerage account with reinvested dividends the drag matters
- Bid/ask spread and transaction costs
- Behavioral realities — real investors rarely hold through the worst drawdowns without selling
