Understanding $75K Over 15 Years
The difference between investment strategies becomes dramatic over 15 years. While a high-yield savings account would grow your $75,000 to $145,146 (a $70,146 gain), the S&P 500 historically would turn it into $313,294 â a difference of $168,147.
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%.
