Annuities are investments issued by insurance companies that can be used to help build a guaranteed income stream or a retirement nest egg. It’s like being able to create your own pension fund or IRA. Annuities come in many varieties, helping investors reach diverse retirement goals.

An annuity is a contract between you and an insurance company in which the company promises to make periodic payments to you, starting immediately or at some future time. You buy an annuity either with a single payment or a series of payments called premiums.

Some annuity contracts provide a way to save for retirement. Others can turn your savings into a stream of retirement income. Still others do both. If you use an annuity as a savings vehicle and the insurance company delays your pay-out to the future, you have a deferred annuity. If you use the annuity to create a source of retirement income and your payments start right away, you have an immediate annuity.
