Annuity - Definition - Adviser Investments Glossary


A financial instrument that pays the holder a guaranteed stream of payments. The annuity is funded by either a lump sum (one-time) or a series of deposits. Once funded, the sum is invested by the insurance company who sold the annuity (the accumulations phase). After a certain trigger (for example, the holder’s retirement or reaching a certain age) payments begin to be issued to the holder (annuitization phase). Annuity payments may be fixed or variable in both amount and in length (some pay out for a designated span of years, others until the holder’s death).
