Whole Life Net Premium Calculator

About this calculator

Whole life insurance premium calculation rests on the actuarial equivalence principle: the expected present value of future premiums the insurer collects must equal the expected present value of the death benefit it will eventually pay. Using a simplified constant mortality rate and a fixed interest (discount) rate, the net level annual premium is derived so these two expected present values balance over the policyholder's remaining lifetime — the same logic behind full actuarial pricing, just without mortality-table granularity.

This calculator takes the face amount, issue age, an interest rate assumption, and a mortality rate, and returns the estimated net annual premium. Actuaries and insurance product designers use models like this in early-stage pricing and teaching to sanity-check more complex mortality-table-based premium calculations, and insurance students and agents use it to understand how sensitive whole life premiums are to changes in interest rate or assumed mortality.
