Many assets provide a series of cash inflows over time; and many obligations require a series of payments. When the payments are equal and are made at fixed intervals, the series is an annuity. There are three types of annuities: (1) (2), and (3) -. One can find an annuity's future and present values, the interest rate built into annuity contracts, and the length of time it takes to reach a financial goal using an annuity.

Fixed annuities

Variable annuities

Indexed annuities

Explanation:

Annuities are defined as contract that pays out regular amounts over time at a particular interest rate.

Usually there is an initial investment of a lumps sum or a series of deposits.

Annuities are classified based on level of risk and payout potential into 3:

- Fixed annuity give out a fixed guaranteed payout amount. The risk is low but the payout is low. Slightly above certificate of deposits.

- Variable annuity is one that gives room for a higher payout but risk is also higher. A set of mutual funds are invested in and payout is dependent on how they perform.

- Indexed annuity gives higher return that is tied to the performance of an index like the S&P 500. The risk is lower than that of variable annuity
