Key Terms and Definitions

Term Definition
Principal (Initial Investment) The starting amount of money you invest. This is the foundation for compound growth and significantly impacts the final value of your investment.
Annualized Return (%) The percentage growth rate of your investment per year. It includes compounding effects and reflects the expected or historical performance of your investment.
Investment Duration The length of time your money remains invested, measured in years. Longer durations amplify the effects of compounding.
Compounding Frequency How often your investment’s interest is calculated and added to the principal. Common frequencies include annual, semi-annual, quarterly, and monthly.
Future Value The total amount of money your investment will grow to over time, including the principal and accumulated interest.

Understanding Compound Interest

Compound interest is the process of earning interest on both your original investment and the interest previously earned. This effect accelerates over time, making it a powerful tool for growing wealth.

For example, an initial investment of $10,000 earning an annualized return of 8% will grow to $21,589.25 after 10 years if compounded annually. The longer the investment duration, the greater the impact of compounding.

Practical Examples of Compound Growth

  • Long-Term Investing: Investing $1,000 annually with a 7% return over 30 years grows to $101,073, illustrating the power of consistent contributions and compounding.
  • High Initial Investment: Starting with a $50,000 principal and a 5% return over 20 years yields a future value of $132,665.
  • Short-Term Compounding: Monthly compounding of $10,000 with a 6% annualized return over 5 years leads to a future value of $13,489.
