Understanding $10K Over 15 Years
The difference between investment strategies becomes dramatic over 15 years. While a high-yield savings account would grow your $10,000 to $19,353 (a $9,353 gain), the S&P 500 historically would turn it into $41,772 â a difference of $22,420.
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%.
