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 41 years the money doubled about 6.4 times. Without reinvesting dividends it would be $368,367: dividends account for 57% of the final value.
Inflation matters over this long. $10,000 in 1986 had the buying power of about $30,564 today, so the real gain is $857,161 against $30,564: still 28.0× the buying power, or 8.5% 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.
