Real monthly S&P 500 data, updated monthly. How we calculate$500 a month into the S&P 500 since Jan 1994 is worth
You would have put in $196,500 over 393 monthly buys. At the worst point, around Mar 2009, the balance was down 45% from its high, and the plan kept buying.
If you had invested the whole $196,500 in Jan 1994, it would be worth $5,744,574. S&P 500 monthly average prices, dividends reinvested (recent months use the last reported dividend, Jun 2023). Data through Sep 2026. One buy per month at that month's average price; no fees or taxes. Past returns do not predict future returns.
The result
That is 393 monthly buys. The balance ended at 8.3× the money put in, a money-weighted return of 10.9% a year. Without reinvesting dividends it would be $1,110,094, so dividends added $529,342.
Prices rose along the way, so the deposits are worth more in today's money than their face value: $196,500 of deposits equals about $311,704 in today's dollars. Even measured that way, the plan ended 5.3× ahead.
The hardest stretch: the balance fell 45% from its high around Mar 2009, during the 2008 financial crisis. Someone who kept buying through that drop bought shares cheaply, which is a large part of the final number.
