An annuity is a series of income payments made at regular intervals by an insurance company in return for a premium or premiums you have paid. The most frequent use of income payments from an annuity is for retirement. An annuity is neither a life insurance nor a health insurance policy. It is not a savings account or a savings certificate. You should not buy an annuity for short-term purposes.
