About Annuities and Future Value

An annuity is a series of equal payments made at regular intervals over a specific period of time. The future value of an annuity is the sum of all these payments plus the interest they earn over time.

Types of Annuities
  • Ordinary Annuity: Payments are made at the end of each period. This is the most common type.
  • Annuity Due: Payments are made at the beginning of each period. This results in more interest earned.
Key Concepts
  • Payment Amount: The amount of each regular payment.
  • Interest Rate: The rate at which the investment grows over time.
  • Payment Frequency: How often payments are made (monthly, quarterly, etc.).
  • Compounding Frequency: How often interest is calculated and added to the balance.
  • Time Periods: The total number of payments to be made.
  • Effective Annual Rate: The actual annual rate when considering the effects of compounding.
