Understanding $500K Over 30 Years
The difference between investment strategies becomes dramatic over 30 years. While a high-yield savings account would grow your $500,000 to $1,872,659 (a $1,372,659 gain), the S&P 500 historically would turn it into $8,724,701 â a difference of $6,852,042.
This is the power of compound growth. The S&P 500's higher average return of ~10% per year compounds exponentially, especially over longer time horizons. However, stocks come with short-term volatility â in any given year, returns can range from -30% to +30%.
