How Age Affects Life Insurance Premiums — and What to Do About It

Every year you wait to get life cover, the cost goes up. Here's the maths — and when to lock in.

Life insurance premiums are calculated primarily on two factors: your age at entry and your health. Every year you delay, the cost of the same cover goes up — sometimes dramatically.

How much does age affect premiums?

Age at entryIndicative monthly premium (500K stepped cover)Relative cost
25$25–$40Base
30$30–$50+20–30%
35$45–$75+80–90%
40$75–$130+200%+
45$130–$220+400%+

Stepped vs level premiums

Stepped premiums increase each year as you age — starting cheap but becoming expensive. Level premiums are fixed at entry and become comparatively cheaper over time. If you're taking out long-term cover, level premiums often win over a 20+ year period.

Action

If you're between 28–35 and have dependants or a mortgage, this is the best window to lock in affordable cover. Don't wait.
