When Sarah, a 35-year-old Melbourne teacher with two young children, asked me "How much life insurance do I need?", she was really asking: "How do I make sure my family never struggles financially if something happens to me?"
This is the single most important question in life insurance, yet most Australians get it wrong. According to recent industry data, the average Australian is may be significantly under-insured—a shortfall that could devastate families when they're most vulnerable.
The challenge isn't that people don't want adequate coverage. It's that calculating your exact needs feels overwhelming. Should you multiply your income by 10? Add up all your debts? Factor in your children's future university fees? The answer is: it depends on your unique circumstances.
In this comprehensive guide, you'll learn three proven methods financial advisers use to calculate life insurance needs:
Each method has its place, and by the end of this article, you'll know exactly which one to use for your situation—and how much coverage you actually need.
Why Under-Insuring Is Dangerous
Consider these real costs Australian families face when a breadwinner passes away unexpectedly:
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.

Before we dive into detailed calculation methods, let's address the quick answer most people want: "Just give me a number."
The most common rule of thumb is:
Life Insurance Coverage = 10x Your Annual Income
For example:
This rule is popular because it's simple to calculate and generally provides reasonable coverage for most working-age Australians.
This rule of thumb works reasonably well if you:
However, this simplified approach can significantly underestimate or overestimate your needs if you:
Under-estimates for:
Over-estimates for:
A 45-year-old with a $150,000 income but no mortgage, grown children, and $800,000 in superannuation probably doesn't need $1.5 million in life insurance. Meanwhile, a 30-year-old earning $80,000 with a $650,000 mortgage and two toddlers likely needs more than $800,000.
Verdict: The 10x rule is better than nothing and provides a reasonable starting point. But for accurate coverage, you need a more personalized approach.

Get Free Coverage AnalysisThe Human Life Value method is the simplest income-replacement approach financial advisers use. It calculates the total income you'd earn from now until retirement, then applies a discount to account for your personal living expenses.
Life Insurance Needed = Annual Income × Years Until Retirement × 0.7
The 0.7 multiplier (70%) accounts for the fact that you won't need to replace 100% of your income—only the portion that supports your family. The other 30% typically covers your personal expenses (car, entertainment, food you consume, etc.).
Example 1: Emma, Age 30
At first glance, $2.2 million seems high for someone earning $85,000. But remember, this is replacing 37 years of income contribution to her household. If Emma has a mortgage and young children, this amount ensures they maintain their living standard without her income.
Example 2: Michael, Age 40
Michael's higher income but fewer working years results in similar coverage needs to Emma. This method naturally adjusts for career stage.
Example 3: Lisa, Age 50
Lisa needs less coverage because she's closer to retirement. Her children are likely older and more independent, and her mortgage is likely smaller after years of payments.

The HLV method works best if you:
However, if you have significant debt, young children with decades of expenses ahead, or complex financial circumstances, you'll want to use the more comprehensive Needs-Based Analysis covered next.
The Needs-Based Analysis is the gold standard for calculating life insurance coverage. Instead of multiplying your income, it itemizes every financial obligation your family would face if you died tomorrow, then subtracts existing assets.
Life Insurance Needed =
(Immediate Expenses + Debt + Income Replacement + Future Goals)
- (Existing Assets)
Let's break down each component:
Immediate Expenses:
Debt:
Income Replacement:
Future Goals:
Existing Assets to Subtract:
Mark and Jessica, Ages 35 and 33
If Mark Dies:
Immediate Expenses:
Debt:
Income Replacement:
Future Goals:
Total Needs: $1,595,000
Existing Assets:
Life Insurance Needed: $1,595,000 - $405,000 = $1,190,000
Recommendation: Mark should carry $1.2 million in life insurance. This ensures Jessica can pay off the mortgage, maintain the family's lifestyle on her part-time income, and provide for the children's education without financial stress.
Most Australian families are under-insured by $400k. Get a free needs analysis to see if you're one of them.
Check Your Coverage GapTom, Age 28
At first glance, you might think Tom doesn't need life insurance. But consider his circumstances:
If Tom Dies:
Immediate Expenses:
Debt:
Income Replacement:
Future Goals:
Total Needs: $91,000
Existing Assets:
Life Insurance Needed: $91,000 - $47,000 = $44,000
Recommendation: Tom should carry $50,000 in life insurance (rounding up). This is a minimal policy—often available for $8-15/month—that ensures his debts don't burden his family and his parents continue receiving his support.
However, if Tom plans to marry or have children in the next 5 years, he should consider locking in a higher coverage amount (e.g., $300,000-$500,000) now while he's young and healthy. Life insurance premiums increase with age, and health conditions that develop later could make coverage more expensive or unavailable.
David and Linda, Ages 55 and 54
If David Dies:
Immediate Expenses:
Debt:
Income Replacement:
Future Goals:
Total Needs: $365,000
Existing Assets:
Life Insurance Needed: $365,000 - $1,060,000 = -$695,000
Recommendation: David and Linda are over-insured. David's superannuation death benefit alone ($520,000) far exceeds their actual needs ($365,000). They should:
This case illustrates why life insurance needs change dramatically over your lifetime. What you needed at 35 with young children is vastly different from what you need at 55 with financial security and independent children.
When calculating immediate expenses, many Australians forget to account for potential medical costs before death. While Australia's Medicare system provides excellent coverage, serious illnesses often come with substantial out-of-pocket costs.
Based on Zurich's "Cost of Care Volume 2" research:
Cancer Treatment:
Heart Disease:
Stroke:
If your family has a history of serious health conditions, consider adding $50,000-$150,000 to your "Immediate Expenses" category to account for potential medical debt that could accumulate before death.
The DIME Formula offers a middle ground between the simplicity of Human Life Value and the comprehensiveness of Needs-Based Analysis. It's an acronym that helps you remember four key categories:
D = Debt I = Income M = Mortgage E = Education
Debt (D): Add up all non-mortgage debts:
Income (I): Calculate income replacement:
Mortgage (M):
Education (E):
Sophie's Situation:
DIME Calculation:
D (Debt): $22,000 + $4,000 = $26,000
I (Income): $105,000 × 12 years (until youngest turns 18) = $1,260,000
M (Mortgage): $520,000
E (Education): 2 children × $75,000 (average university cost) = $150,000
Total DIME: $26,000 + $1,260,000 + $520,000 + $150,000 = $1,956,000
Minus existing assets:
Life Insurance Needed: $1,956,000 - $280,000 = $1,676,000
Recommendation: Sophie should carry approximately $1.7 million in life insurance coverage.
The DIME method works best when you:
The main limitation is that it doesn't account for immediate expenses (funeral costs) or future goals beyond education (first home deposits, spouse retraining, etc.). Add $50,000-$100,000 to your DIME total to cover these additional needs.

Compare Life Insurance QuotesWhile every situation is unique, here are typical life insurance coverage amounts Australians need at different life stages:
| Life Stage | Age Range | Typical Coverage | Key Considerations |
|---|---|---|---|
| Young Singles | 20-30 | $100,000-$300,000 | Covers debts (HECS, car loans, credit cards) and funeral costs. Low premiums make it worth locking in coverage early. |
| Young Couples (No Kids) | 25-35 | $300,000-$600,000 | Covers shared mortgage/debts and replaces income so surviving partner can maintain lifestyle. |
| Young Families | 30-40 | $750,000-$1,500,000 | Peak insurance need. Large mortgages + decades of child-raising costs + education funding. |
| Established Families | 40-50 | $1,000,000-$2,000,000 | Still high needs, but mortgage declining. May need more for private school fees and university coming soon. |
| Pre-Retirees | 50-60 | $300,000-$800,000 | Needs declining. Children independent, mortgage nearly paid. Focus shifts to income protection. |
| Retirees | 60+ | $100,000-$300,000 | Minimal needs. Mainly covers funeral, outstanding debts, and estate equalization among children. |
Your income significantly impacts the coverage amount you need because it determines your family's lifestyle and replacement costs:
| Annual Income | Young Family (30s) | Established Family (40s) | Pre-Retiree (50s) |
|---|---|---|---|
| $60,000-$80,000 | $600,000-$900,000 | $500,000-$750,000 | $200,000-$400,000 |
| $80,000-$100,000 | $800,000-$1,200,000 | $700,000-$1,000,000 | $300,000-$500,000 |
| $100,000-$150,000 | $1,000,000-$1,500,000 | $900,000-$1,300,000 | $400,000-$700,000 |
| $150,000+ | $1,500,000-$2,500,000 | $1,300,000-$2,000,000 | $500,000-$1,000,000 |
Note: These are guidelines only. Your actual needs depend on debt levels, number of dependents, existing assets, and future goals.
Certain situations may require significantly higher coverage than typical for your age/income:
Business Owners:
Single Parents:
Large Mortgages:
Children with Disabilities:
Private School Education:
Life insurance isn't "set and forget." Your coverage needs change as your life circumstances evolve. Here are the major life events that should trigger a coverage recalculation:
The Problem: Many Australians think, "If I die, I just need to pay off the house. So I'll get coverage equal to my mortgage."
Why It's Wrong: Paying off a $600,000 mortgage leaves your family with a house but zero income. They still need to eat, pay bills, cover education costs, and maintain their lifestyle.
Example: David has $650,000 in life insurance to "cover the mortgage." When he dies, his wife Sarah gets a paid-off house but no money to:
Sarah is forced to sell the house anyway because she can't afford to live in it without David's income.
Fix: Use the Needs-Based Analysis or DIME Formula. The mortgage is just one component of your coverage needs.
The Problem: People calculate based on current expenses and forget that children get more expensive as they age.
Why It's Wrong: Your 5-year-old's current childcare costs ($18,000/year) will be replaced by:
Example: Lisa calculates that her family needs $55,000/year to maintain their lifestyle. She multiplies by 15 years = $825,000 in coverage. But she forgets:
She's actually $400,000 under-insured.
Fix: When using income replacement, add separate line items for major future expenses (education, first cars, home deposits).
The Problem: You buy life insurance at age 30 with $400,000 coverage. Now you're 42 with two children, a larger mortgage, and you haven't reviewed it once.
Why It's Wrong: Your 30-year-old self had completely different needs than your 42-year-old self. Your coverage is likely off by $500,000 or more in either direction.
Real Example: James bought $500,000 in coverage at 28 when he was single and renting. Now 38, he has:
His actual needs: $1.4 million. His coverage: $500,000. Gap: $900,000.
If James dies, his wife gets $500,000. After paying off the $650,000 mortgage, she has -$150,000 (goes into debt) and zero income replacement for raising the children.
Fix: Review coverage every 2-3 years and after every major life event (marriage, children, property purchase, divorce, significant income change).
The Problem: You calculate you need $1 million today and lock in a level premium policy with fixed $1 million coverage for 20 years.
Why It's Wrong: $1 million in 20 years will only buy what $550,000 buys today (assuming 3% inflation). Your coverage loses purchasing power every year.
Example: In 2006, $500,000 could buy a good Sydney house. In 2026, $500,000 is a deposit on a Sydney house. If you bought $500,000 in coverage in 2006 and never increased it, you've lost 60% of your actual coverage.
Fix:
Answer: Life insurance becomes "too much" when:
Example of too much: A 55-year-old with $1.2 million in superannuation, grown independent children, and a paid-off house probably doesn't need $2 million in life insurance. The premiums are wasted money that could go into super or retirement savings.
General rule: Your coverage should be enough to maintain your family's lifestyle, pay off debts, and fund future goals—but no more. Over-insurance wastes thousands in annual premiums that could be better invested.
However, it's nearly impossible to "over-insure" young families. If you're 35 with two toddlers and a large mortgage, $1.5-2 million is not excessive—it's adequate.
Answer: Always round up to the nearest $50,000 or $100,000. Here's why:
Reasons to round up:
Example: You calculate you need $1,230,000. Round up to $1,250,000 or $1,300,000. The extra $70,000 costs approximately $10-20/month but provides important buffer.
Exception: If you're on a tight budget, round to the nearest $50,000 ($1,230,000 → $1,250,000) rather than $100,000 to keep premiums manageable.
This is a common dilemma for young families who need substantial coverage ($1-2 million) but have tight budgets.
Solutions:
Term Life Instead of Whole Life
Laddering Strategy
Prioritize the Primary Breadwinner
Start with Minimum Viable Coverage, Increase Later
Look for Through-Super Options
Reduce Other Insurance Temporarily
Important: Don't let perfect be the enemy of good. $750,000 in coverage is infinitely better than $0 in coverage. Get what you can afford now, then increase it.
