How Much Life Insurance Do You Really Need in Australia in 2026?

Most people buy a home, have children, and assume the life insurance attached to their super fund will be enough if something goes wrong.

It’s an easy assumption to make.

You log into your AustralianSuper, Hostplus or another super account, see that you have life cover, and think, “At least my family will be okay.”

But then you look at the numbers.

Imagine a family with a $650,000 mortgage and around $180,000 of life insurance through super. That $180,000 might sound like a lot, but once the mortgage, childcare, everyday living expenses, and future education costs are considered, the gap can become surprisingly large.

This is why the old rule of simply taking 10 times your annual salary doesn't work for everyone.

A person renting with no children has very different financial responsibilities from a family with three young children, a large mortgage, and one main income.

So, how much life insurance do you actually need?

One useful starting point is the DIME method.

What Is the DIME Method?

Quick answer: There is no single amount of life insurance that is right for every Australian. A useful starting point is to calculate your mortgage and other debts, the income your family may need to replace, future education and childcare costs, and the value of unpaid household work, then subtract existing savings and insurance cover. The result gives you an estimated protection gap to discuss with a qualified adviser.

DIME is a simple way of looking at the major financial responsibilities your family could be left with if you were no longer around.

It stands for:

• D – Debt
• I – Income replacement
• M – Mortgage
• E – Education

Let's look at each one.

D — Debt

Start with your non-mortgage debts and liabilities.

This could include:

• Car loans
• Personal loans
• Credit cards
• Buy-now-pay-later balances
• Business debts you have personally guaranteed

The idea is simple: you don't want your family using your life insurance payout just to clear debts that could otherwise have been accounted for.

I — Income Replacement

This is often the biggest part of the calculation.

Ask yourself:

How much income would my family need if I wasn't there to provide it?

You don't necessarily need to replace your entire salary forever.

Instead, think about how many years your children or other dependants would realistically need financial support.

For example, if your family needs approximately $95,000 a year and you want to provide that support for 12 years:

$95,000 × 12 = $1,140,000

Your circumstances may produce a very different number.

M — Mortgage

For many Australian families, the home loan is their largest liability.

If your mortgage balance is $650,000, you need to decide whether your life insurance should be sufficient to clear the entire loan or whether your family could comfortably continue making repayments.

Paying off the mortgage isn't the only possible strategy, but it should be part of the conversation.

E — Education

Think beyond university fees.

Depending on your family, education-related costs could include:

• Childcare
• Preschool
• School fees
• Uniforms and technology
• Tutoring
• University
• TAFE or trade training

You don't have to predict every dollar your children will spend. The goal is to build a sensible buffer for the costs you expect your family to face.

Putting the Numbers Together

Let's use a simple example.

Imagine a family with a young child, a $650,000 mortgage and approximately $95,000 of annual income that needs to be replaced for 12 years.

This is only an example, not a recommendation for every family.

But it shows why a simple “10 times your salary” calculation can sometimes produce a very different result.

At $95,000 of income, the 10× rule would suggest $950,000.

That sounds substantial.

But in this example, the family's estimated financial need is considerably higher once the mortgage, debts, income replacement and education costs are included.

Don't Forget the Value of Unpaid Work

There is another part of the calculation that families sometimes overlook.

What happens if the person who stays home with the children dies?

There may be no salary to replace, but there are still costs associated with the work that person was doing every day.

Childcare, school pickups, after-school care, household help and other responsibilities may suddenly have to be paid for.

The surviving partner may also need to reduce their working hours.

So when reviewing life insurance, don't only ask:

“How much does this person earn?”

Also ask:

“What would it cost our family if this person was no longer here to do the things they currently do?”

That can produce a very different answer.

Don't Assume Your Super Insurance Will Stay the Same

Life insurance through super can be useful, but don't assume the amount you see today will necessarily remain unchanged throughout your working life.

Depending on the fund and policy, cover can change as you get older, your circumstances change, or your account becomes inactive.

That's why it's worth checking your actual insurance details rather than relying on what you remember from when you first opened your super account.

Look at:

• The amount of cover
• Your premium
• Your age-based changes to cover
• Any eligibility requirements
• What happens if your super account becomes inactive

If you're unsure, ask your super fund for the current policy details.

You Don't Have to Put All Your Cover in One Place

For some Australians, a combination of insurance inside and outside super may make sense.

For example, someone might retain a level of cover through super and have additional personal cover outside super to address the remaining gap.

There can be differences in premiums, ownership, taxation, policy features and claims processes, so this isn't a one-size-fits-all decision.

The important thing is to look at your total protection, rather than simply asking whether you have life insurance.

So, How Much Life Insurance Do You Need?

There isn't a magic number that works for every Australian family.

Your ideal level of cover depends on things such as:

• Your mortgage
• Other debts
• Number and age of your children
• Household income
• Number of years your family may need financial support
• Education plans
• Savings and investments
• Existing insurance through super
• The financial contribution made by each partner

The DIME method is simply a starting point to help you put those pieces together.

And you don't need to spend an entire weekend doing it.

Start with your mortgage balance, debts, annual household requirements and expected education costs. Then subtract the savings and insurance you already have.

The number left over gives you a much clearer picture of the financial gap your family may need to cover.

The goal isn't to buy the biggest policy you can afford. It's to have enough protection for the people who depend on you.

If you're unsure whether your existing life insurance is enough, reviewing your current cover with a qualified insurance adviser can help you understand where you stand.
