The chart uses a log scale: equal steps up mean equal percentage gains. What each line measures: S&P 500, S&P 500 monthly average level with dividends reinvested (an index fund, before its small fee). Inflation uses the US Consumer Price Index. Monthly averages, data through Sep 2026; no fees or taxes. Past returns do not predict future returns.
The result
Over 76 years the money doubled about 11.8 times. Without reinvesting dividends it would be $361,594: dividends account for 90% of the final value.
Inflation matters over this long. $1,000 in 1951 had the buying power of about $13,188 today, so the real gain is $3,479,513 against $13,188: still 263.8× the buying power, or 7.6% a year above inflation.
It was not a smooth ride. The value fell 49% from a high around Mar 2009, during the 2008 financial crisis. Holding through it was the price of the final number.
