Real monthly S&P 500 data, updated monthly. How we calculate$500 a month into the S&P 500 since Jan 2019 is worth
You would have put in $46,500 over 93 monthly buys. At the worst point, around Mar 2020, the balance was down 13% from its high, and the plan kept buying.
If you had invested the whole $46,500 in Jan 2019, it would be worth $153,065. 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 93 monthly buys. The balance ended at 1.9× the money put in, a money-weighted return of 16.7% a year. Without reinvesting dividends it would be $83,863, so dividends added $5,149.
Prices rose along the way, so the deposits are worth more in today's money than their face value: $46,500 of deposits equals about $53,703 in today's dollars. Even measured that way, the plan ended 1.7× ahead.
The hardest stretch: the balance fell 13% from its high around Mar 2020, during the 2020 COVID crash. Someone who kept buying through that drop bought shares cheaply, which is a large part of the final number.
