Frequently Asked Questions
Is this a realistic financial projection?
No, this is a fun illustrative exercise based on pure compounding from a single starting amount — real wealth building typically involves ongoing contributions, varying market returns, and rarely follows a single fixed growth rate for decades.
Why does a small change in growth rate make such a big difference?
Compound growth is highly sensitive to the rate used over long time periods, so even a few percentage points of difference in assumed annual growth can change the projected timeline by many years or even decades.
What growth rate is realistic for long-term investing?
Historical long-term stock market returns have averaged around 7 to 10 percent annually before inflation, though individual results vary significantly and past performance does not guarantee future returns.
