Understanding Mortality Credits in Annuities

In this video, Denzel Rodriguez explains mortality credits, the extra income that longer‑lived annuitants receive in a lifetime annuity. He describes how an insurer pools the mortality risk of all policyholders: when a participant dies earlier than expected, the funds that would have been paid to them are redistributed to those who survive longer, effectively boosting the payouts to the latter. Using a simple classroom example with ten people of varying ages, he shows that early deaths (e.g., Denzel) reduce the insurer’s obligations, while the longest‑living participants (e.g., Carlos and Ruth) receive higher guaranteed income because they are closer to mortality. He emphasizes that this risk‑pooling mechanism benefits the insurer—who remains insulated from individual longevity risk—and benefits long‑lived individuals, who enjoy higher income for a longer period.
