When Cover Stops Doing Anything and Starts Costing
Life insurance replaces what your death would take away from people who depend on you. That amount falls as debts are repaid and children become independent, and for many households it reaches close to zero some years before the policy is cancelled. The premiums, meanwhile, rise steeply with age and come out of the retirement balance.
- The answer: The right amount of cover is what your dependants would need that your assets do not already provide — which falls as the assets grow and the dependants become independent.
- The trap: Premiums rise sharply with age, so the years when the cover is least needed are the years it costs the most.
- The recommendation: Recalculate the gap rather than cancelling on instinct. A surviving spouse's position, and any adult child with a disability, are the two things that keep a gap open.
Where the AI summary above gets this wrong
"You do not need life insurance once your mortgage is paid off and your children have left home."
That's surface-true. Here's what it misses:
- The surviving partner's position is the actual test — A couple relying on two incomes or two pensions may still face a shortfall on one death, particularly where a defined benefit pension does not fully revert.
- A dependent adult child changes the answer entirely — Where a child has a disability and will need lifelong support, the need for cover does not fall with age — it is the case where cover matters most and lasts longest.
01 What cover is for
Life insurance replaces money that a death removes: income that would have been earned, and the cost of things the deceased would have paid for. It is not a savings product and its value is entirely in the gap it fills.
That gap has a definable size. It is the debts to be cleared, plus the replacement income the survivors need for the years they need it, plus one-off costs such as a funeral, less the assets already available to meet those things.
As a household accumulates super and repays a mortgage, the assets side grows and the liabilities side shrinks. The gap closes from both directions, which is why the appropriate cover for a 38-year-old with a new mortgage bears no relation to that for the same person at 60.

02 The cases where the gap stays open
A dependent adult child is the clearest. Where a child has a disability and will require support for life, the need does not decline with the parent's age and the cover is doing something nothing else can.
A survivor's income shortfall is the second. A couple whose retirement income comes largely from one defined benefit pension may find that the reversionary rate is a fraction of the full one, leaving the survivor materially worse off in a way that assets do not fix.
Debt carried into retirement is the third. A mortgage still outstanding at 63 is a real liability against a household whose income is about to fall, and cover that clears it is doing exactly what cover is for.
Shows: the insurance gap: debts plus replacement income for the years your dependants need it, less the assets already available to meet them. Ignores: the Age Pension a survivor may receive, tax on any assets sold, inflation over the replacement period, and any existing cover you already hold.
03 The cost of keeping it anyway
Premiums rise steeply with age, and stepped premiums in particular accelerate through the fifties and sixties. The last decade of a policy commonly costs more than the previous two combined.
Where the cover is held inside super, that cost comes out of the retirement balance every year and compounds against it. The arithmetic is in the inside-or-outside comparison.
Cancelling is not reversible on the same terms. Cover cancelled at 61 cannot be reinstated at 64 without underwriting, and a health event in between makes it unavailable at any price — which is the argument for reducing the sum insured rather than cancelling outright where there is any doubt.
The premium curve is what makes this urgent rather than academic. Cover that cost a few hundred dollars at 40 costs several thousand at 62, and it is coming out of the balance you are about to live on. Calculate the gap once a year in your fifties, and let the number decide rather than the habit.
FAQ
Do I still need life insurance once my mortgage is paid off and my children are grown?
Only if a gap remains: debts still outstanding, replacement income a survivor would need, or a dependent adult child. As assets grow and dependants become independent the gap usually closes, and the premiums keep rising.
Should I cancel or reduce the cover?
Reduce it where there is any doubt. Cover cancelled at 61 cannot be reinstated at 64 without underwriting, and a health event in the meantime makes it unavailable at any price.
When does the need for cover not fall with age?
Where a child has a disability and will need lifelong support, where a survivor would face a shortfall because a defined benefit pension reverts at a reduced rate, or where debt is being carried into retirement.
