Stepped vs Level Premiums NZ: Where the Two Lines Actually Cross

There are two crossover points in New Zealand life insurance, and almost every article confuses them. On the worked example LifeDirect publishes for a 35-year-old non-smoker with $250,000 of cover, the yearly cost of stepped cover passes the level rate at age 52. The running total does not pass it until age 64. Twelve years separate the moment level starts looking cheaper from the moment it actually is.

That distinction decides the question. If you cancel your policy at 58 because level was "cheaper from 52", you paid the higher price for six years and never collected. This page charts both lines, from published New Zealand rates, and shows the arithmetic.

If you want the concepts first, our companion guide to stepped versus level premiums in NZ covers how each structure works, hybrid options and the decision framework. This page is the maths.

The figures this page is built from

LifeDirect publishes a worked New Zealand example it calls Julie: a 35-year-old non-smoker with $250,000 of life insurance, paying $15 a month in stepped premiums today, $222 a month at 65, and $1,500 a month at 80, which LifeDirect notes is $18,000 a year. It also publishes what locking in at 35 would have done, at $30.89 a fortnight.

Figures for a 35-year-old non-smoker with $250,000 of life cover, reproduced from LifeDirect. LifeDirect states the savings figures are before inflation. Published illustration only, not a quote. LifeDirect is a New Zealand insurance distributor and publishes this example while selling both structures.

Two things follow from that table by pure arithmetic. The level rate of $30.89 a fortnight is $803.14 a year. And LifeDirect's own saving of $20,225 by age 70 means that over the 35 years from 35 to 70 the stepped policy costs about $48,335 while the level policy costs about $28,110.

When does the yearly cost cross over?

At 52, on these figures. The level rate is fixed at $803.14 a year from the day the policy starts. The stepped premium starts at $180 a year and compounds at about 9.4 percent to reach the $2,664 a year LifeDirect publishes at 65, then at about 13.6 percent to reach its published $18,000 a year at 80. It passes the level rate in the policy's eighteenth year.

Yearly figures. The 35, 65 and 80 stepped rows and the level row are the annualised figures LifeDirect publishes; the rest are QuoteHub interpolations between them. Published illustration only, not a quote.

This is the crossover that gets quoted. It is real, and it is not the one that decides anything, because by age 52 the stepped policyholder has spent seventeen years paying less.

When does the money actually cross over?

At 64. Up to that point the stepped policyholder is still ahead on everything paid so far, because the early savings have to be repaid before level wins. The chart below is the same policy, plotted as a running total rather than a yearly cost.

Three numbers in that table are worth reading properly. The level policyholder is worst off at about 50, roughly $6,600 down, and that is the pit she has to be willing to sit in. From there the gap closes steadily and disappears at 64. After 64 the divergence is violent: by 80 the stepped policyholder has paid nearly four times as much.

How reliable is that crossover?

Reliable enough to act on, and we can show why. Our reconstruction produces a cumulative saving of $436,250 by age 90 against the $437,083 LifeDirect publishes for the same policy, a difference of about two tenths of one percent. At the nearer checkpoints our version is conservative: it produces $15,786 saved by 70 where LifeDirect publishes $20,225, and $103,191 by 80 where LifeDirect publishes $123,345.

Conservative in this direction matters. If LifeDirect's own numbers imply a steeper stepped curve than our smooth interpolation, then the true crossover arrives slightly earlier than 64, not later. So 64 is a late estimate, not an optimistic one.

The method is simple enough to repeat. Take the three stepped costs LifeDirect publishes, at 35, 65 and 80. Fit a constant compounding rate between each pair, which gives 9.4 percent a year to 65 and 13.6 percent after it. Multiply the published fortnightly level rate by 26 for the level line. Then add the two up, year by year, and see where the totals meet.

Does an insurer rate card give the same answer?

Yes, within a couple of years, and from an entirely different source. KiwiCover publishes AIA's standard premium rates as at 20 March 2025 for $500,000 of life cover on both bases, which is the clearest side-by-side rate card on a New Zealand website. Running the same calculation on it gives a running-total crossover in the low sixties at every entry age.

Rates for $500,000 of life cover, male non-smoker, as published by KiwiCover from AIA's standard rates at 20 March 2025, including AIA's standard policy fee and excluding discounts. The two crossover columns are QuoteHub calculations, interpolating between KiwiCover's published ten-year age points and extrapolating the last decade at the rate of the one before it. Published illustration only, not a quote.

Two published sources, two different rate bases and two different sums insured, and both land the money crossover between 61 and 68. That is a much narrower answer than the "somewhere in your fifties" that circulates, and it is a materially less flattering one for level cover.

The entry-age column is the other lesson in that table. Level to 80 costs 2.77 times the first-year stepped rate if you lock in at 30, and 3.39 times if you wait until 40. Level premiums are not expensive in themselves. They are expensive to start late, which is a point we develop in the cost of waiting to buy life insurance in NZ.

What has to be true for level to pay off

You have to still hold the policy at 64, at the same sum insured, and still want it. That is the whole condition, and it is a stronger condition than it sounds. New Zealand life cover is commonly bought against a mortgage and a young family, and both of those obligations shrink. A policyholder who reduces cover at 55 because the mortgage is gone has bought the expensive half of the level deal and sold the cheap half.

LifeDirect's second published example shows the other side of it. Mark switched to level at 51, locking his premium at $84 a month, and at 59 is still paying $84 for his $250,000 of cover where stepped would have put him between $124 and $145 a month depending on the insurer. Switching later means a higher locked rate, but it also means a much shorter wait to break even, because the stepped line is already climbing steeply by then.

There is also a partial option that gets overlooked. LifeDirect notes you do not have to move the whole premium: you can put part of the sum insured on level and leave the rest stepped, which caps the early cost while protecting the part of the cover you expect to hold longest.

Honest limits on all of this

Level does not mean guaranteed. LifeDirect states that insurers can apply across-the-board adjustments to a book of level policies, and that if your policy carries automatic inflation indexation both the sum insured and the price rise each year. So the flat line in our charts is the age-based component being frozen, not a contractual promise that the number never moves.

Level also ends. KiwiCover explains that at the end of the level period the premium converts to rate for age if the benefit has not expired, which means a level-to-65 policy steps onto the stepped curve at 65 at a 65-year-old's rate. Only the level-to-80 and level-to-100 versions carry the fixed rate through the years where the stepped curve does its real damage.

Two more caveats. Every figure on this page is for a healthy applicant at standard rates, and a loading or exclusion from underwriting changes both lines. And the totals ignore the time value of money entirely, which is LifeDirect's own stated basis. Being about $6,600 down by 50 in order to save six figures by 80 is still a good trade at any plausible discount rate, but the raw totals overstate how good.

Who each structure suits

Stepped suits a cover need with an end date you can name. A twenty-year mortgage, cover until the youngest child finishes study, a business loan with a term on it. If the need runs out before your early sixties, stepped is cheaper on every published figure we have, and there is nothing clever about paying more for certainty you will not use.

Level suits cover you expect to hold for life or close to it, taken out young enough that the multiple is bearable. On the AIA card that means locking in at 30 rather than 40 wherever possible, because the starting multiple goes from 2.77 to 3.39 across that decade alone. It also suits anyone whose health is likely to change, because a level rate is set once, on the underwriting you pass today.

If neither describes you, the honest answer is that it does not matter much yet, and that the more valuable decision is whether the sum insured is right. Our life insurance calculator works that out, and the price context by age sits in life insurance price by age in NZ.

Frequently Asked Questions

At what age do stepped and level premiums cross over in NZ?

On published New Zealand rates there are two answers. The yearly cost crosses in your early to mid fifties, at 52 on LifeDirect's worked example for a policy started at 35 and at 50 to 60 on AIA's rate card depending on entry age. The total amount paid crosses much later, between 61 and 68 on the same sources.

Which crossover should I use to decide?

The running total, because that is the number you actually pay. The yearly crossover only tells you the moment the level policyholder stops feeling worse off month to month. Deciding on the yearly crossover and then cancelling before the total crosses is the single most expensive mistake available in this decision.

How much more does level cost at the start?

On AIA's published rates for $500,000 of cover, level to 80 starts at 2.77 times the first-year stepped rate for a male non-smoker aged 30, 3.39 times at 40 and 3.07 times at 50. So the multiple is at its lowest at the youngest ages, which is the opposite of what most people assume.

Can level premiums still go up?

The age-based component does not, but the premium can. Insurers can review rates across a whole book of level policies, and automatic inflation indexation raises both your cover and your premium each year if your policy has it. Level freezes your age, not the insurer's pricing.

What happens at the end of the level period?

The premium converts to rate for age if the benefit continues, at your age at that date. A level-to-65 policy therefore steps onto a 65-year-old's stepped rate at 65, which is exactly the point on the curve where the increases get steep. Check which level period you are being quoted.

Is level worth it if I might cancel early?

No, on these figures. Everything level gives you sits on the far side of the running-total crossover. If there is a real chance you will reduce or cancel cover in your fifties, stepped costs less and a partial level split is the compromise worth asking about.

Do these numbers apply to trauma and income protection too?

The shape does, but the crossover ages do not transfer. Trauma and income protection have their own claim-risk curves and their own level pricing, and the crossover has to be worked out on the product's own rate card. Treat the figures on this page as life cover only.
