What if you invested monthly in the S&P 500 for 5 years?

Why this period and asset
July 2021 fell near all-time highs during the post-pandemic liquidity rally. This plan then ran straight into the sharp rate hikes and inflation of 2022, when the S&P 500 fell substantially from its peak, before rebounding through 2023-2024 on strength in large AI-linked names. In other words, these 5 years compress a full cycle of entering near a high, falling, and recovering.
Interpreting the result
Over a span as short as 5 years, when you started and the volatility along the way dominate the result far more than compounding does. This window still contained a large maximum drawdown and a meaningful stretch underwater; you had to sit below your invested cost before the recovery could lift you. Dollar-cost averaging keeps buying at lower prices during declines, so those near-bottom purchases became the springboard for the rebound. A single 5-year result, however, says little about the index's long-run character.
Caveats & limits
This is a simplified simulation that ignores taxes, trading fees, and currency effects. Past performance does not guarantee future returns and reflects one specific start date. Figures here follow USD-based prices; actual returns in another currency depend on exchange rates.

Frequently asked questions
Does this result include dividends?
It is based on SPY price data and does not separately model dividend reinvestment or dividend taxes. In practice, dividends and their taxes affect real outcomes.
Is 5 years long enough to be 'long-term'?
Five years typically covers roughly one decline and recovery, which is short for judging an index's long-run compounding. That is why entry timing shows up so strongly.
How is the contribution date handled?
It assumes a fixed amount invested near the start of each month. Real auto-transfer dates or fill prices can shift the details slightly.
