Annuity: An annuity is a financial product that provides a series of payments made at equal intervals over time, typically used for retirement income or investment purposes. It is characterized by its predictable cash flows, making it easier for individuals to budget and plan their finances. Annuities can be structured in various ways, including fixed or variable payments, and can be immediate or deferred, impacting their present value significantly.
Annuity Due: An annuity due is a series of equal payments made at the beginning of each period over a specified time frame. This payment structure affects the present value and future value calculations, as the earlier timing of payments leads to a higher total value compared to ordinary annuities, which pay at the end of each period. The unique cash flow timing is crucial in evaluating investment options and planning for financial goals.
Compound Interest: Compound interest is the interest calculated on the initial principal and also on the accumulated interest from previous periods, allowing for exponential growth over time. This concept is crucial for understanding how investments and savings can grow significantly due to the effects of earning 'interest on interest', impacting present value, future value, and the effective annual rate of financial products.
Compounding: Compounding is the process in which interest is added to the principal amount of an investment or loan, allowing future interest to be calculated on the accumulated interest as well. This process is crucial for understanding how investments grow over time, as it affects calculations related to present value, future value, annuities, forward rates, and spot rates. The frequency of compounding can significantly impact the total returns or costs associated with financial products.
