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); Bonds, total return of 10-year US Treasury bonds (interest plus price changes), modelled from the monthly 10-year yield. Inflation uses the US Consumer Price Index. Monthly averages, data through Aug 2026; no fees or taxes. Past returns do not predict future returns.
The result
Over 71 years the money doubled about 10.3 times. Without reinvesting dividends it would be $173,713: dividends account for 86% of the final value.
Inflation matters over this long. $1,000 in 1956 had the buying power of about $12,499 today, so the real gain is $1,276,180 against $12,499: still 102.1× the buying power, or 6.8% 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.
