Understanding $100K Over 3 Years
The difference between investment strategies becomes dramatic over 3 years. While a high-yield savings account would grow your $100,000 to $114,117 (a $14,117 gain), the S&P 500 historically would turn it into $133,100 â a difference of $18,983.
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%.
