Key Concepts

Annuity

An annuity is a financial product or arrangement that provides for a series of equal payments made at regular intervals over a specified period. It is commonly used in retirement planning and loan amortization, where an initial sum is converted into a stream of periodic disbursements.

Present Value of an Annuity

The present value of an annuity is the total current worth of a series of future annuity payments, discounted back at a specific interest rate. It helps in determining how much money is needed today to secure a specific series of future withdrawals.

Periodic Interest Rate

The periodic interest rate is the interest rate applicable to each compounding period rather than the annual rate. It is calculated by dividing the annual interest rate by the number of compounding periods per year, which is essential for accurately computing the growth or depletion of funds when payments occur more frequently than once a year.

Annuity Payment Formula

The annuity payment formula links the present value of an annuity, the periodic payment amount, the periodic interest rate, and the number of periods. It provides a method for calculating the fixed amount that can be withdrawn or paid out at regular intervals so that the principal is fully exhausted by the end of the period.

Compounding

Compounding refers to the process where interest is earned not only on the initial principal but also on the accumulated interest from previous periods. In the context of annuities, compounding plays a critical role in determining the effective growth of the initial sum, thereby influencing the size of the periodic withdrawals.
