Starting early vs late: the cost of waiting 10 years?
We view the difference between someone who invested for 20 years and someone who started late and invested only 10 through the lens of method. The key is the power of 'time' as a method, and the opportunity cost of waiting.

Method · Comparison
The biggest variable in compounding is 'time.' The earlier you start, the more early declines and underwater periods you face, but the money that endures those crises gains time to snowball over the long run. Starting late can avoid the big early drops, but pays the opportunity cost of not fully capturing the later growth where compounding truly gathers force. Still, starting early is not always advantageous, and you must also weigh that it meant enduring several large maximum drawdowns along the way. The start date is a matter of readiness to stay the course, not prediction.

The 20 years from July 2006 to July 2026 passed through the 2008 financial crisis, the 2020 pandemic crash, and the 2022 correction, yet rose sharply over the long run. An early starter faced more crises but secured longer compounding time, while a late starter avoided the early crisis but missed that much of the growth.
Caveats & limits
Declaring that starting early is 'always a gain' is risky. Results depend on the start date and the market phase that follows, and early money had to endure more crises. This comparison is a simplified simulation that ignores taxes, fees, and currency effects, and past performance does not guarantee the future. As a USD asset, returns in won depend on exchange rates.

Frequently asked questions
Did starting early or late win?
For an asset that rose over the long run, starting early tends to win by securing more compounding time. But early money had to endure more early crises, and results shift with the market phase, so it is not always the case.
When is a good time to start?
Rather than picking a start by prediction, the right time is when you are ready to stay the course. Waiting for a perfect entry and letting time pass is itself an opportunity cost in compounding terms. What matters is not stopping during downturns after you start.
If I start late, is it already too late?
No. Since the key is securing as long a remaining horizon as possible, starting now gains more compounding time than delaying further. Just note that the shorter the remaining horizon, the more entry timing and volatility relatively matter.
