How much life insurance do you actually need
Most Australians need 8 to 12 times their annual income in life insurance cover. Young families with a mortgage and two children typically land at $750k to $1.5M; pre-retirees with paid-off debts often need $200k to $500k.
That range is the starting point, not the answer. Your real number depends on your specific debts, income, dependents, and existing assets. This guide walks through three methods used by financial advisers to refine the estimate.
The challenge isn't that people don't want adequate coverage. It's that calculating exact needs feels overwhelming. Should you multiply income by 10? Add up all debts? Factor in future university fees? The answer depends on your unique circumstances.
In this guide, you'll learn three proven methods financial advisers use:
Quick Income Approach - Income-based (fastest, 2 minutes)
DIME Formula - Memory trick approach (balanced, 10 minutes)
Each method takes a different approach, and by the end you'll have three different ways to estimate how much coverage you might need. Better yet, you'll understand why each calculation produces the number it does, so you can explain it to your spouse or adviser with confidence.
Why Under-Insuring Is Dangerous
Consider these real costs Australian families face when a breadwinner passes away unexpectedly:
Average mortgage debt: $580,000 (2026 data)
Cost to raise two children to age 18: $812,000 (ABS, excluding education)
University fees per child: $50,000-$150,000 (HECS-HELP debt)
Lost income replacement (20 years): $1.8M-$2.4M for $90k-$120k earners
Emergency medical costs before death: Cardiac and cancer treatment can carry material out-of-pocket costs even with Medicare and private health insurance (gap fees, specialist consultations, allied health, lost income during treatment) (Source: AIHW Health Expenditure Australia)
Without adequate life insurance, families often face impossible choices: sell the family home, withdraw children from private school, or take on debt just to maintain basic living standards.

Why Simple Rules Don't Work (And Why We Have Better Methods)
You've probably heard "get 10 times your income in life insurance." That sounds easy. But it fails in the real world.
The 10x rule assumes:
You have a typical mortgage (not huge, not tiny)
You have 0-2 kids (not 3+)
You earn in the middle range (not very low or very high)
You have a typical timeline (working another 20-30 years)
But real people don't fit these assumptions.
A 28-year-old single person earning $75,000 needs maybe $300,000 (not $750,000). A 42-year-old with three kids and a $900k mortgage earning $130,000 needs maybe $2.2 million (not $1.3 million). The rule oversimplifies.
That's why we have three methods that adapt to YOUR situation. They take 2-20 minutes but give you the right answer for your life.
Quick Calculator: Your Starting Point
Let's figure out your coverage needs in under 2 minutes.
Step 1: Your Quick Number

These figures are illustrative only and based on the information you have entered. They do not take into account your personal financial situation, needs, or objectives. Work through the full version covering TPD, trauma and income protection, or compare quotes across 9 insurers.
Examples:
Earn $60,000? → Start with $450,000
Earn $90,000? → Start with $675,000
Earn $120,000? → Start with $900,000
This is your quick starting point, not your final answer, just a ballpark to work from.
Step 2: Does This Sound About Right?
Quick gut check. You might need MORE if you:
Have young children (under 12)
Have a large mortgage ($700k+)
Have multiple dependents
Are the sole income earner
You might need LESS if you:
Are close to retirement (55+)
Have grown children
Have paid off most debts
Have substantial super or savings
What's Really Going On?
That quick number works for average situations. But here's the truth: your family's actual needs are specific to you.
Why? Because life insurance needs to cover:
Your current debts (mortgage, car loan)
Years of lost income your family relies on
Future expenses (kids' education, first homes)
Minus money you've already saved
The 5-10x rule assumes you have typical debts and a typical family. But if you're above or below average in any category, you're either over-insured or under-insured.
So let's do this properly. Pick the calculation method that matches the level of detail you want.
How to Use This Guide
If you have 2 minutes: Do the quick calculation at the start of "Method 1." It's not perfect, but it's a starting point.
If you have 20 minutes: Jump to "Method 2: The Detailed Worksheet." It's the most accurate and helps you understand exactly where your coverage need comes from.
If you want the balance: Try "Method 3: The DIME Shortcut." It's easier than Method 2 but more thoughtful than Method 1.
The sweet spot for most people: Method 2 or Method 3. Spend 15-20 minutes, get your actual number, and you're done. That's not a burden, it's one email worth of time to protect your family.
Calculate Your Exact Coverage Needs
Get an indicative life insurance comparison based on your actual financial situation, not generic rules of thumb.
Best for: People with average situations who want a fast answer.
The simplest way to estimate coverage is to think about how many years of your family's income you need to replace.
The Idea
Your family doesn't need to replace 100% of your income (you won't be eating and driving anymore!). But they do need enough to maintain their lifestyle until kids finish school or they adjust.

Illustrative starting point$840,000

These figures are illustrative only and based on the information you have entered. They do not take into account your personal financial situation, needs, or objectives. Work through the full version covering TPD, trauma and income protection, or compare quotes across 9 insurers.
Examples in Plain Language
Sarah, age 32, earns $80,000 with two young kids:
Family needs income replacement for ~15 years (until kids are independent)
$80,000 × 15 × 0.7 = $840,000 starting point
Her real answer: probably $1.1M (because mortgage and education aren't included)
Tom, age 28, single, no kids:
Needs income replacement for ~10 years (longer career ahead, build savings)
$75,000 × 10 × 0.7 = $525,000 starting point
His real answer: probably $300,000-$400,000 (minimal dependents)
When This Works Best
This approach is good if:
You want a ballpark number in 2 minutes
You have an average family situation
You'll use a more detailed method later anyway
But be warned: It ignores your mortgage and specific debts, so it's often inaccurate. Most people need to use Method 2 or 3 for a real answer.
Method 2: The Detailed Worksheet (Most Accurate)
Best for: Getting your actual coverage number based on your real finances.
This method asks: "What would my family actually need if I died tomorrow?" Then you add up all the expenses and subtract what you've already saved.
The Simple Worksheet
Work down the three sections. What they would owe, plus what they would need, minus what they already have.

If the answer is negative, you're already covered. If it's positive, that's your gap.
Real Example: Mark and Jessica (Young Family)
Their situation:
Mark: 35 years old, earns $95,000
Jessica: 33, earns $70,000 (part-time), kids aged 4 and 7
This ensures Jessica can cover debts, maintain lifestyle, and fund the kids' education without selling the house or taking on debt.
How mortgages, school fees and other commitments factor into cover amounts
The worksheet works because each big commitment enters as its own line item rather than being buried in a multiplier. The outstanding mortgage balance is usually counted in full, so the family home is secured outright regardless of what happens to income. Education is counted per child, and the schooling choice moves the number a long way: private school fees can add $30-40k per year per child as a distinct line, while a public schooling plan shifts most of the cost into the ordinary income-replacement line instead. Car loans, credit cards and any business borrowings are added at their payout figures.
The useful property of itemising commitments is that the calculation ages with you. Each year the mortgage shrinks and each child moves closer to independence, so rerunning the same worksheet produces a smaller target number over time, which is exactly why review points matter (see the checklist below).
Quick Facts About Different Life Stages
Young singles (20s-30s):
Need: $200,000-$400,000
Covers: debts + funeral + parent support
Cost: ~$15-25/month
Young families (30s-40s):
Need: $1-2 million
Covers: mortgage + 15 years income + kids' education
Cost: ~$50-100/month
Pre-retirees (50s-60s):
Need: $300,000-$800,000 (or maybe none)
Mortgage likely lower, super substantial
Check your calculation, you might be over-insured
Method 3: The DIME Shortcut (Balanced Approach)
Best for: Getting a defensible number you can explain to your spouse.
DIME is a memory trick for the four main things life insurance needs to cover:
D = Debt (mortgage, car, credit cards)
I = Income (years of earnings to replace)
M = Mortgage (already counted? just the balance)
E = Education (kids' university)

DIME does not explicitly include funeral costs. Add $15,000 to $20,000 to the figure above to allow for them.
These figures are illustrative only and based on the information you have entered. They do not take into account your personal financial situation, needs, or objectives. Work through the full version covering TPD, trauma and income protection, or compare quotes across 9 insurers.
Quick Example: Sophie
Debts: $26,000
Income replacement: $105,000 × 12 years = $1,260,000
Mortgage: $520,000
Education: 2 kids × $100,000 = $200,000
Total: $2,006,000
Minus assets ($280,000): $1.7 million needed
Note: DIME doesn't explicitly include funeral costs. Add $15,000-20,000 to your final answer to cover that.
When to Use DIME
You want a quick but accurate number
You need something you can explain easily
The worksheet approach felt like too much detail
Limitation: It's less precise than the full worksheet because it uses rough estimates. But it's still much better than the 10x rule.

Checklist: When You Actually Need to Review Coverage
Life happens. These are the moments you should recalculate:
Mandatory reviews (do within 3 months):
Got married or moved in with a partner
Had a baby or adopted
Bought property
Got divorced or separated
Started a business
Serious health diagnosis
Regular reviews:
Every 2-3 years (set a calendar reminder)
After a big salary increase
When kids finish school
Ages 50, 55, 60 (approaching retirement)
Your situation might be special:
Single parent? Add 20-30% to your calculation
Large mortgage? Make sure you cover the full balance
Kids with disabilities? Get specialist advice, needs can exceed $2-5M
Private school? Add $30-40k/year per child to future costs
When Should You Increase Cover, and When Should You Decrease It?
The checklist above tells you when to look; the direction usually follows the obligations. Cover generally moves up after events that add financial dependants or debt: a new baby, a larger mortgage, a partner dropping to one income, or a salary increase your household now lives on. Cover generally moves down as those obligations retire: the mortgage paid well below its original balance, children finishing study and becoming independent, or a super balance now large enough to fund part of the need itself.
The mechanics differ by direction. Reducing cover is usually a simple request to the insurer and takes effect from the next premium. Increasing cover typically means new health questions on the increased amount, so an increase is easier to obtain while you are healthy than after a diagnosis. Some policies include future-increase or guaranteed-insurability options that allow set increases after defined life events without full underwriting; whether yours does is in the PDS.
Coverage by Your Situation
Here's what the worksheet usually produces for different people (use these as sanity checks):
Single, no kids, $70k income:
Debts: $30,000
Income replacement (10 years): $490,000
Assets: $40,000
Coverage needed: $480,000 → round to $500k
Monthly cost: ~$20-30
Reality check: This person isn't in a huge rush, but locking it in early is smart
Young family, $95k income, two kids, $580k mortgage:
Debts + funeral: $610,000
Income replacement (15 years): $1,000,000
Education (2 kids): $200,000
Assets: $250,000
Coverage needed: $1,560,000 → round to $1.6M
Monthly cost: ~$60-80
Reality check: This is peak insurance need. Heavy but necessary.
Established family, $125k income, one kid left, $200k mortgage:
Debts + funeral: $220,000
Income replacement (10 years): $875,000
Education (1 kid): $100,000
Assets: $400,000
Coverage needed: $795,000 → round to $850k
Monthly cost: ~$40-50
Reality check: Needs declining as kids age and debts reduce. Good time to keep it stable for 10 more years.
Reality check: Super alone covers needs. Can reduce or cancel private policies. Focus on income protection instead.
These aren't your exact numbers, they're examples of how the calculation works. The patterns: young families need the most, it declines over time, and pre-retirees often find they don't need much at all.
How Do You Tell If You're Underinsured or Overinsured?
Both directions are measurable with the same two numbers: the worksheet result above, and your total existing cover. Add up everything you already hold, including the default cover sitting inside super that many people forget about (a super insurance check shows the default amounts by fund and age). Then compare.
If your total cover sits well below the worksheet figure, the gap is the underinsurance, and it is concrete: it is the part of the mortgage or the income-replacement years that would go unfunded. If your total sits well above the figure, and the calculation reflects your current debts and dependants rather than the ones you had a decade ago, you may be paying premiums for cover the framework no longer supports.
Neither result is a recommendation on its own. The worksheet is one framework, and the output is illustrative. But running it against your actual cover total turns a vague worry ("do I have enough?") into a number you can act on in either direction.
Don't Make These Mistakes
Mistake 1: Mortgage-only coverage
Paying off a house leaves your family homeless if they have no income. Coverage must include 10-15 years of income replacement plus education costs.
Mistake 2: Forgetting future expenses
Your 5-year-old will cost a lot more at 15. Include braces, cars, university, and all the big teen/young adult expenses.
Mistake 3: Never reviewing
You bought $400k coverage at 30. Now you're 42 with a mortgage and two kids. That $400k is nowhere near enough. Review every 2-3 years.
Mistake 4: Ignoring inflation
$1 million in 20 years buys what $550k buys today. Choose policies with indexation (auto-adjust) or manually increase coverage every few years.
Quick Answers to Common Questions
Q: How much is too much coverage?
If you're 35 with young kids and a big mortgage? $1.5-2M is not too much, it's appropriate. If you're 60 with grown kids and paid-off house? $500k+ is probably too much. Rule of thumb: coverage should pay debts and replace income until retirement.
Q: Should I round up or down?
Always round up. The difference between $950k and $1M is usually $5-10/month in premiums. That extra buffer is worth it.
Q: What if I can't afford the coverage I need?
Get term life (not whole life, 60-80% cheaper). Start with what you can afford now ($500k-750k), then increase in a few years. Something is infinitely better than nothing. Through-super coverage is also cheaper ($1-3/week).
Q: Can I replace my life insurance once I'm older?
It gets expensive and risky. Buy it when you're young. If you only have $300k now at age 35 but expect to need $1M when kids are born, lock in the full $1M now while premiums are low. Rates double every 10-15 years.
Can Someone Walk You Through the Calculation, Not Just Sell You a Policy?
Yes, with an honest boundary worth understanding. A licensed broker operating under a general advice model can explain each method on this page, work through the worksheet lines with you, point out inputs people commonly miss (default super cover, per-child education costs), and then show what different cover amounts actually cost across a panel of insurers. That is the "sit down and work it out" help most people are looking for.
The boundary: general advice does not assess your personal circumstances and does not recommend a specific amount. The figures stay illustrative and the decision stays yours; a personal recommendation would require a personal advice service, which is a different (and typically fee-charging) engagement. If you would rather start on your own, the needs calculator runs the same illustrative worksheet online, and a 15-minute call can walk through the inputs afterwards.
Your Action Plan: Calculate & Protect
You have three methods to choose from. Here's how to pick:
Choose Method 1 (Quick Income) if:
You want a ballpark number in 2 minutes
You're not ready to dig into details yet
You'll come back to Method 2 or 3 later
Choose Method 2 (Worksheet) if:
You have a specific situation (mortgage, kids, debts)
You want your actual coverage number
You're willing to spend 20-30 minutes
This is usually the best choice for accuracy
Choose Method 3 (DIME) if:
Method 2 felt overwhelming
You want something you can explain to your spouse
You're an "acronym person" and like mental shortcuts
Your 30-Minute Action Plan
Step 1: Pick your method (2 minutes)
Read which method above matches your style.
Step 2: Gather your numbers (10 minutes)
Have your bank statements and mortgage documents handy. Write down:
Step 3: Do the calculation (10 minutes)
Use the formula/worksheet for your chosen method. Don't overthink it, estimates are fine.
Step 4: What you got vs. what you have (5 minutes)
Coverage you calculated = What you need
Existing insurance = What you have
The gap = What to buy
Step 5: Get a quote (3 minutes)
You now have a number. Shop around. Term life insurance is usually 60-80% cheaper than whole life for the same coverage.
Real Talk
The average Australian is under-insured by $400,000. Most people discover this too late. Don't be a statistic. This 30-minute calculation could save your family from financial ruin.
And here's the thing: You'll feel genuinely better once it's done. That's not dramatic, it's the relief of knowing your family is protected.
One Final Thing: Get Quotes
Once you have your number, get 2-3 quotes. Prices vary wildly:
Same coverage, different insurers: Can vary by $50-150/month
Term vs. whole life: Term is 60-80% cheaper
Age matters: Buy it now. Premiums roughly double every 10-15 years.
A 35-year-old getting $1M in coverage? Might be $50-80/month (term). Same person 10 years later? Could be $120-200/month. Lock it in early.
Pro tip: Use an online comparison tool to check multiple insurers at once. It's free and takes 5 minutes. That small effort could save you thousands over 20 years.
