How a whole life policy is structured — the split between base premium and paid-up additions — has a significant effect on how quickly cash value builds and how much capital is available for deployment. This article explains the difference between the two components and why the structure matters for banking practitioners.
The Two Premium Components
A whole life policy for banking purposes is typically funded through two separate streams:
Base premium — the minimum required premium to keep the whole life policy in force. Base premium is primarily directed toward the death benefit. It guarantees the policy stays active, funds the insurance carrier's mortality and expense charges, and builds cash value — but cash value growth relative to total premium paid is slower in the early years.
Paid-up additions (PUA) rider — an optional rider that allows you to contribute additional premium beyond the base. PUA contributions are used to purchase small, fully paid-up units of whole life insurance. Each unit requires no future premium to remain in force and immediately adds to both cash value and death benefit. Because PUAs are fully paid-up at purchase, a high proportion of each PUA contribution goes directly into cash value — typically 85-95% or more, depending on the policy design.
