Understanding $15K Over 3 Years
The difference between investment strategies becomes dramatic over 3 years. While a high-yield savings account would grow your $15,000 to $17,117 (a $2,117 gain), the S&P 500 historically would turn it into $19,965 â a difference of $2,848.
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%.
