Understanding $3K Over 15 Years
The difference between investment strategies becomes dramatic over 15 years. While a high-yield savings account would grow your $2,500 to $4,838 (a $2,338 gain), the S&P 500 historically would turn it into $10,443 â a difference of $5,605.
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%.
