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); Gold, gold monthly average price in US dollars per ounce; 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 42 years the money doubled about 6.8 times. Without reinvesting dividends it would be $44,694: dividends account for 59% of the final value.
Inflation matters over this long. $1,000 in 1985 had the buying power of about $3,175 today, so the real gain is $108,351 against $3,175: still 34.1× the buying power, or 8.8% 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.
