Deferred annuities grow capital by investment in the accumulation phase (or deferral phase) and make payments during the distribution phase. A single premium deferred annuity (SPDA) allows a single deposit or premium at the issue of the annuity with only investment growth during the accumulation phase. A flexible premium deferred annuity (FPDA) allows additional payments or premiums following the initial premium during the accumulation phase.
The phases of an annuity can be combined in the fusion of a retirement savings and retirement payment plan: the annuitant makes regular contributions to the annuity until a certain date and then receives regular payments from it until death. Sometimes there is a life insurance component added so that if the annuitant dies before annuity payments begin, a beneficiary gets either a lump sum or annuity payments.
