Compare two health plans with similar cover and the premiums can differ by almost double. How? The answer usually hides in the premium structure — whether it steps up with age or stays level. Let's understand both systems, because this is one of the longest-lasting decisions in health planning.
Stepped premiums
This is the structure of most health insurance. The premium is calculated on your current age band: light when young, then rising as you enter each new band, reflecting health risk increasing with age.
- Advantages: cheap to start and easy to access, suited to early working years on a limited budget. Full cover from day one without paying a lot.
- What to know: the premium from 55–70 and beyond rises markedly — precisely the period when many people's income falls after retirement. Without planning ahead, you may have to reduce the cover or cancel it at the age you need it most.
Level premiums
A structure that averages the cost across the whole contract into the same premium every year. It is found in long-term health contracts or plans where premiums are paid for a period and cover continues afterwards, according to each plan's conditions.
- Advantages: you can budget precisely for the long term with no anxiety about premiums in old age — paying more while you still have income, in exchange for peace of mind after retirement.
- What to know: the early premium is significantly higher than the stepped version, because it amounts to paying in advance for your older self. And if you cancel partway, the excess paid in the early years may not be fully realised. Conditions differ by plan [check the conditions in the policy].
Seeing them side by side
Picture two lines on a graph. The first (stepped) starts low and climbs ever more steeply. The second (level) starts higher but runs flat and straight. The two cross at a point. Someone who holds the contract long enough passes that crossing point into the territory where level is better value; someone holding for a short time may never reach it. So the question is not "which is cheaper?" but "how long will I hold it, and at which stage of life is my budget tightest?"
Choosing by situation
- Early career, limited budget: stepped premiums give you cover immediately without affecting your savings, to be reviewed as income grows.
- Mid-career with stable income: a good moment to consider a level premium or a short payment term, locking in the burden before retirement.
- Approaching retirement: what matters is estimating the post-retirement premium of your current plan and arranging the source of money to pay it — investment returns, or annuity income. Don't wait for the bill to surprise you.
- The middle path: some people mix the two — a core plan that can be planned long term, supplemented by a stepped plan for extra cover during the years it is needed.
Questions to ask before signing
Always ask for the premium table by age for that plan, through to the age you intend to hold it. Ask whether the premiums shown are guaranteed or adjustable and on what conditions [check the conditions in the policy]. And calculate the cumulative premium of both structures at your target age — that figure will tell you which structure answers your life.
