Why this period and asset
July 2001 sat in the middle of the deflating dot-com bubble. The next 25 years include the 2000-2002 dot-com aftermath, the 2008 global financial crisis, the 2020 COVID crash, and the 2022 rate-hike period. The early 2000s in particular were the era of the 'lost decade' debate, when the index languished and early contributions hovered near cost for years.
Interpreting the result
The heart of this window is 'what if you kept contributing through the most crises.' A large 2008 maximum drawdown and a long early-2000s stretch of losses and recovery recurred, and the first several years were a frustrating time when money added barely grew. Dollar-cost averaging kept buying at low prices during these declines, so accumulated share count powered later recoveries. But note that stopping midway would have forfeited those low-price purchases.
Caveats & limits
This is a simplified calculation without taxes, fees, or currency effects. The fact that three past crises recovered does not guarantee future recoveries. As a dollar asset, returns in another currency depend on exchange rates.

Frequently asked questions
Are all three crashes really included?
From a 2001 start, the late dot-com decline, the 2008 crisis, and the 2020 COVID crash all fall inside this window, each with its own drawdown and loss period.
Would it have been better to stop during the early slump?
In hindsight, stopping might have missed low-price buying. But that is after-the-fact data, not advice guaranteeing future results.
Are dividends included?
The calculation uses price data and does not separately model dividend reinvestment or taxes. In reality, dividends and taxes affect performance.
