How much life insurance do I need? (Australia)
How to work out how much life insurance you need in Australia — a simple framework covering debts, income replacement, dependants and final costs, and why the amount changes as your life changes.
"How much life insurance do I need?" has no single answer, because it depends entirely on who relies on you and what would need paying for if you were gone. But there is a clear, sensible framework to estimate it — and it beats guessing or defaulting to whatever your super happened to set.
The needs-based approach
Rather than a vague multiple of income, add up what your family would actually need, then subtract what you already have. Think of it in four buckets:
- Debts to clear. The mortgage, car loans, credit cards and any other debt you would not want left to your family.
- Income to replace. Your income for the number of years your dependants would need support — often until children are independent or a partner can manage alone.
- Future costs. Big known expenses like children's education, or funds to keep the household running.
- Final expenses. Funeral and estate costs, plus a buffer so grieving family are not making financial decisions under pressure.
Add those together, then subtract your existing savings, assets you would sell, and any life cover you already hold (including inside super). What remains is a realistic target for new cover.
Don't forget cover you already have
Many Australians hold default life cover inside their superannuation. Check your super statement before buying more — you may have a base already, and topping it up can be cheaper than starting fresh. Just be aware default cover is often modest and may not match a proper needs-based figure.
Stepped vs level, and affordability
The right amount also has to be affordable long term, or you risk cancelling it when you most need it. As with income protection, life cover can be stepped (cheaper now, rising with age) or level (higher now, more stable over time). Pick an amount and structure you can realistically sustain.
Why the number keeps changing
Life insurance is not set-and-forget. The right cover shifts with every major change:
- Taking on a mortgage increases what you need
- Having a child increases it again
- Paying down debt over time reduces it
- Children becoming independent reduces it further
Reviewing the amount at each renewal keeps you from being under-insured when your family is most exposed — or over-paying for cover you have outgrown.

How much life insurance do I need?⌄
A common approach is to add up what your family would need if you were gone: clearing debts (including the mortgage), replacing your income for a set number of years, funding your dependants' future costs, and covering final expenses — then subtracting savings and any existing cover.
Is there a rule of thumb for life insurance?⌄
Some people use a multiple of annual income (for example 10 times), but that is only a rough starting point. A needs-based calculation that reflects your actual debts, dependants and goals gives a far more accurate figure.
Does life insurance inside super count towards what I need?⌄
Yes. Any default or additional cover you hold inside superannuation forms part of your total, so include it before deciding how much extra you need. Many Australians already hold some life cover through their super without realising it.
How often should I review my life insurance amount?⌄
Review it whenever your circumstances change — a new mortgage, a child, a change in income — and otherwise at least once a year. The right amount early in your career is rarely the right amount a decade later.
