An annuity is a contract between you and an insurance company, under which you make a lump-sum payment or series of payments. In return, the insurer agrees to make periodic payments to you beginning immediately or at some future date. Annuities typically offer tax-deferred growth of earnings and may include a death benefit that will pay your beneficiary a guaranteed minimum amount, such as your total purchase payments.

There are generally two types of annuities-fixed and variable. In a fixed annuity, the insurance company guarantees that you will earn a minimum rate of interest during the time that your account is growing. The insurance company also guarantees that the periodic payments will be a guaranteed amount per dollar in your account. These periodic payments may last for a definite period, such as 20 years, or an indefinite period, such as your lifetime or the lifetime of you and your spouse.
