−39%Worst drop on the way

That is 309 monthly buys. The balance ended at 6.0× the money put in, a money-weighted return of 12.1% a year. Without reinvesting dividends it would be $346,495, so dividends added $119,026.

Prices rose along the way, so the deposits are worth more in today's money than their face value: $77,250 of deposits equals about $111,773 in today's dollars. Even measured that way, the plan ended 4.2× ahead.

The hardest stretch: the balance fell 39% 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.
