Understanding $1K Over 20 Years
The difference between investment strategies becomes dramatic over 20 years. While a high-yield savings account would grow your $1,000 to $2,412 (a $1,412 gain), the S&P 500 historically would turn it into $6,727 â a difference of $4,316.
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%.
