If you had invested $1,000 in the S&P 500 in 2020
Month by month, in dollars of each date and in today's dollars, with the worst fall on the way and the same money in other assets.
That is what $1,000 put in the S&P 500 in January 2020, when the index averaged 3,278 points, would be worth by October 2026. Prices rose by 30.2% in that time, so its purchasing power grew by 99.6%: 10.8% a year after inflation, 15.2% before.
The same money elsewhereOver the same years it would have become $917 in Treasuries, $2,630 in gold, $8,270 in bitcoin, $12,500 in ether (in today's dollars). Kept as cash, its purchasing power fell by 23.2%.
On the way it fell 19.3%From $1,470 in Dec 2021 to $1,190 in Oct 2022, in dollars of those dates.
Monthly averagesShiller's S&P 500 prices are averages of daily closes in each month, so the start and end values are not exact closing prices; dividends are reinvested every month.
No taxes or feesThe numbers ignore taxes, fees, commissions and spreads: a real investor would have kept somewhat less.

How it is calculated
- What is counted. S&P 500: the index with dividends reinvested every month (Robert Shiller's data; before 1957 a reconstruction, see the S&P 500 page). Treasuries: a 10-year US government bond bought new every month, coupons reinvested (Shiller's bond returns). Gold: the World Bank's monthly average price. Bitcoin and ether: the Coin Metrics price on the last day of each month. Cash: dollars kept at home, earning nothing.
- Monthly steps. Money goes in at a month's value and the result is read at the end month's value. Shiller's S&P 500 prices, the bond yields and gold are monthly averages, which smooth out moves inside a month: the real highs and lows were somewhat more extreme.
- Worst fall is the largest drop from a high to a later low within the period, using the monthly values; “real” also counts inflation. Falls inside a month are not seen.
- Today's dollars are Oct 2026 dollars: a value is multiplied by the rise in US consumer prices (CPI-U; before 1913 the Warren and Pearson reconstruction) from its date to Oct 2026. “Real” returns are after this inflation.
- No taxes, fees or spreads. Real investors paid commissions, fund fees, and taxes on dividends, coupons and gains, so they kept less than shown here.
- Preliminary data. S&P 500 dividends from July 2026 on are estimated from the last known value. Shiller's notes on the latest month: Oct price is Oct 2nd close; Sept/Oct CPI estimated; Oct GS10 is Oct 2nd value.
