Real monthly S&P 500 data, updated monthly. How we calculate$250 a month into the S&P 500 since Jan 2024 is worth
You would have put in $8,250 over 33 monthly buys.
If you had invested the whole $8,250 in Jan 2024, it would be worth $13,567. 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 33 monthly buys. The balance ended at 1.3× the money put in, a money-weighted return of 19.2% a year. Without reinvesting dividends it would be $10,372, so dividends added $157.
Prices rose along the way, so the deposits are worth more in today's money than their face value: $8,250 of deposits equals about $8,594 in today's dollars. Even measured that way, the plan ended 1.2× ahead.
The hardest stretch: the balance fell 0% from its high around Mar 2026. Someone who kept buying through that drop bought shares cheaply, which is a large part of the final number.
