Understanding $20K Over 20 Years
The difference between investment strategies becomes dramatic over 20 years. While a high-yield savings account would grow your $20,000 to $48,234 (a $28,234 gain), the S&P 500 historically would turn it into $134,550 â a difference of $86,316.
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%.
