What if you invested a small amount monthly in the S&P 500 for 10 years?
A small monthly amount is something even a first-time earner can start. The key point is that, in percentage terms, the outcome is identical to a much larger amount.

Why this period and asset
The decade from July 2016 to July 2026 contains a steady rise, the late-2018 correction, the early-2020 pandemic crash, the deep 2022 rate-hike drop, and the AI-led rebound that followed. Whether small or large, contributions pass through the same phases, and the ratio of the maximum drawdown and underwater periods is the same regardless of amount.
Interpreting the result
Even with a small contribution, ratio-based metrics like return and maximum drawdown are exactly the same as with a large amount. A small plan's final value looks modest in absolute terms, but starting early during a low-income stage and keeping it up secures compounding time. This decade still held a deep phase below cost, and not stopping through it became the springboard for recovery. A small amount does not change the nature of the outcome; what matters is 'how long and how consistently,' not 'how much.'
Caveats & limits
This is a simplified simulation that ignores taxes, trading fees, and currency effects. With small amounts, fee and conversion costs can weigh relatively more in reality. Past performance does not guarantee the future and reflects one specific start date. As a USD asset, returns in won depend on exchange rates.

Frequently asked questions
Is investing a small amount meaningful?
Percentage returns are identical regardless of amount, so a small plan carries the same nature of outcome. The key is starting early during a low-income stage to secure compounding time, then raising the amount as your capacity grows.
Does a bigger amount improve the return?
No. Ratio metrics like return and maximum drawdown do not scale with amount — they are the same. Increasing the amount only scales the final absolute figure; the ratio of doing well or poorly does not change.
Were there any losses over the 10 years?
Yes. This window still had a deep phase below cost and a meaningful stretch underwater. Continuing to buy at lower prices instead of stopping then became the springboard for the later recovery.
