Why life insurance costs rise with age
Life insurance gets more expensive as you age because mortality risk roughly doubles every 7-10 years. Insurers use Australian Life Tables (national death statistics by age and gender) to price each year of cover.
The good news: this is predictable. Understanding the curve lets you make smart timing decisions that can save tens of thousands of dollars over a 20-year policy.
This guide explains what drives your life insurance costs, the difference between premium types (stepped vs level), and practical strategies to keep costs manageable. Whether you're 25 and thinking about your first policy or 50 reviewing what you have, understanding the math helps you decide when to buy and what type makes sense for your situation.
Important: This is general information only. You should consider whether life insurance is appropriate for you and seek personal advice from a licensed financial adviser before making decisions.
What Affects Your Life Insurance Cost?
Life insurance costs depend on several factors, but they all come down to one question: "How likely is the insurer to need to pay out?" The higher your risk, the higher your premium.
The big ones:
Age - The single biggest factor. A 30-year-old pays a fraction of what a 50-year-old pays for identical coverage.
Gender - Women pay 20-40% less than men because they live longer on average.
How much coverage you need - Bigger amounts cost more, but not proportionally more (there's an economy of scale).
Your health - High blood pressure, weight, diabetes, or mental health history can increase costs.
Your job - Office workers pay less than construction workers or electricians.
The smaller ones that still matter:
Whether you want stepped premiums (increase every year) or level premiums (stay the same for a fixed period)
Your lifestyle (do you skydive or rock climb?)
Your income (for income protection policies)
The good news? Most of these factors you either can't change (age happens, gender is what it is) or can change strategically (quit smoking, lose weight, change jobs). We'll cover the ones you can control later.
Understanding Premium Structures
How Age Affects Premiums: Why Costs Jump
Life insurance premiums don't increase smoothly year by year. Instead, they jump faster and faster as you age, and here's why:
Mortality risk roughly doubles every 7-10 years. That's the core insight. It's not that a 50-year-old is 10% more likely to die than a 49-year-old, it's that mortality compounds over time.
Think of it like compound interest, but working against you. If someone at 25 has a mortality risk of, say, X%, then by age 35 it's roughly 2X%, by 45 it's 4X%, by 55 it's 8X%, and so on.
What this means for your premiums on a stepped policy (the most common type):
Ages 25-35: Premiums increase about 5-7% per year
Ages 35-50: Premiums increase about 7-9% per year
Ages 50-65: Premiums increase about 9-12% per year
Ages 65+: Premiums increase about 12-15% per year
So a 30-year-old might see their premium go from $50 to $55 one year (a $5 increase). A 55-year-old seeing a similar percentage increase might see their premium go from $500 to $560 (a $60 increase). The percentage is similar; the dollars are very different.
After age 50 it accelerates further because that's when serious health conditions (heart disease, cancer, diabetes) start becoming common. The statistics reflect reality: your health profile changes more dramatically in your 50s than in your 30s.
Can you see in advance how your premium will change as you age?
Yes, and it is worth asking for before you buy. On a stepped policy, next year's premium is not a mystery: it comes off the insurer's published rate-for-age table, so an illustrative year-by-year projection can be produced at quote time rather than discovered one anniversary at a time. When comparing quotes, ask to see the projected premium at five, ten and twenty years alongside the first-year price.
That projection is also the honest way to compare stepped against level premiums. A level policy starts higher but holds its rate, so somewhere in the projection the lines cross; where they cross depends on your age and the insurer's pricing. Rate tables are not contractually guaranteed (insurers can reprice a whole rate series), so treat projections as illustrative, but they are far more informative than a single first-year figure.
Smoking: The 50-100% Premium Penalty
Here's a real example using current panel data: A 30-year-old male non-smoker pays a premium within the indicative panel range for $500,000 coverage. That same person as a smoker pays materially higher than non-smoker rates (commonly approaching double). That's roughly double (Source: LRO API panel data, indicative range).
Why? Smoking dramatically increases your risk of heart disease, cancer, and stroke, the three things that kill people. Insurers price accordingly.
The smoking multiplier is:
Ages 25-35: About 1.8-2.2x regular rate (roughly 80-120% more)
Ages 35-50: About 1.6-2.0x regular rate (roughly 60-100% more)
Ages 50+: About 1.5-1.8x regular rate (roughly 50-80% more)
Younger smokers get hit harder as a percentage. Older smokers get hit hard in absolute dollars (because the base rate is already high).
Important: Insurers classify you as a smoker if you've used tobacco or nicotine in the past 12 months. This includes:
Cigarettes, cigars, pipes
Vaping/e-cigarettes with nicotine
Nicotine patches or gum (after the first 3 months of quitting)
The good news, and it's genuinely good: After 12 months smoke-free, you can request to be reclassified as a non-smoker. Most insurers just need a signed declaration, though they may ask for medical evidence (blood test). The premium drops immediately and permanently.
Current panel data shows a 30-year-old non-smoker pays for $500k cover, while a same-age smoker pays roughly double, meaning the saving from non-smoker reclassification approximately halves the monthly figure (Source: LRO API panel data, indicative range). That compounds significantly over a 30-year policy.
Gender: Why Women Pay Less
Women pay 20-40% less than men for the same coverage. The reason is straightforward: women live longer. Australian women have a life expectancy of 85.4 years versus 81.6 years for men (about a 4-year difference). More importantly for insurance pricing, women have lower death rates at every single age from 25 onwards.
This isn't discrimination, it's basic statistics. The same logic means women sometimes pay more for trauma/critical illness cover (they're statistically more likely to survive and claim), but less for life and disability cover.
The difference is largest in the 35-50 age range, where women typically pay 30-35% less than men.
Bigger Coverage = Lower Cost Per $1,000
Here's something that surprises people: doubling your coverage amount doesn't double your cost.
Why? Because insurers have fixed costs (paperwork, underwriting, management) whether you're insuring $250k or $1M. So:
Moving from $250k to $500k might increase your premium by only 45-55% (not 100%)
Moving from $500k to $1M might increase cost by only 60-70% (not 100%)
The practical takeaway: Don't buy less coverage than you need just to save money. A smaller policy actually costs you more per $1,000 of cover. If cash flow is tight, it's better to buy the full coverage you need than to buy a smaller amount at a lower total cost.
Stepped vs Level: Which Should You Choose?
This decision matters more than most people realize because it affects not just your next year's cost, but your total cost over the life of the policy.
How They Work (The Simple Version)
Stepped premiums: Start cheap and go up every year, typically by 7-10% annually. You're paying the "current" rate for your current age. At 35 you pay a 35-year-old rate; at 45 you pay a 45-year-old rate.
Level premiums: Start higher (often 40-60% higher than stepped), but stay flat for a fixed period (usually to age 65, 70, or 75). No annual increases during that period.
The Long-Term Math
Here's what actually happens:
Years 1-15: Stepped premiums cost less. You're paying lower rates early on.
Years 15-20: They're roughly even.
Year 20+: Level premiums become cheaper because stepped premiums have been compounding for 20+ years, and those increases have stacked up.
The crossover point (where level becomes cheaper) is typically around year 15.
But here's the catch: When your level period ends at, say, age 65, your premium converts to stepped rates for your age at that time. That conversion can be shocking, current panel data shows a 60-year-old male non-smoker already pays a premium within the indicative panel range for $500,000 cover on stepped premiums (Source: LRO API panel data, indicative range), and a 65-year-old faces even higher stepped rates. Someone converting from decades of level premiums will see a very significant jump almost overnight.
Which One for You?
Go with stepped premiums if:
You only plan to keep coverage for 10-15 years (until kids are independent, mortgage is paid)
You want the lowest starting costs
You're comfortable with costs increasing each year
You're stretching your budget and need to minimize monthly outlay
Go with level premiums if:
You genuinely plan to keep coverage for 20+ years
You're buying in your 30s (you want to lock in low rates for a long time)
You want certainty and hate surprises on your premium bill
You'd rather pay more now to protect against cost increases later
You want protection if your health deteriorates (future rates won't be higher because of a new health issue)
The honest truth: Level premiums only make financial sense if you actually keep the policy 15+ years. Don't buy them thinking you might cancel early, you'll end up overpaying.
Understanding Coverage Amount Economics
The cost per $1,000 of cover decreases as you purchase larger coverage amounts. This "economy of scale" effect exists because insurers have fixed costs (underwriting, paperwork, management) regardless of whether you're insuring $250k or $1M.
If you double your coverage, your premium doesn't double. Instead:
Moving from $250k to $500k might increase cost by only 45-55% (not 100%)
Moving from $500k to $1M might increase cost by only 60-70% (not 100%)
The takeaway: Don't buy less coverage than you need just to save money. You'll end up paying more per $1,000 of protection.
How Do You Check If You're Overpaying for Your Current Policy?
The easiest check is a like-for-like requote: get fresh quotes for the same cover amount, cover type and premium structure you hold today, and put them next to your current renewal notice. If the market prices the same cover materially below what you pay, that gap is real information; if it does not, your policy is priced about where the market is.
Two traps to avoid when running this check. First, an annual increase on a stepped policy is the structure working as designed, not evidence of overpaying; compare your renewal against what a new stepped policy would cost at your current age, not against what you paid at 35. Second, a cheaper quote is only a saving if the features match: a lower premium with a weaker TPD definition or a shorter terminal illness benefit period is a different product, not the same product cheaper. And if you do decide to move, never cancel existing cover until the replacement policy is issued and in force.
How to Lower Your Life Insurance Costs
The factors you can't control (age, gender) are fixed. But several factors you can control. Here's where you can actually save money:
1. Buy Young (The Biggest Lever)
This is the single most important decision. Buying at 30 instead of 40 can save you 30-40% on level premiums, and 60-70% over the lifetime of a stepped policy. Every year you wait, costs increase.
The hidden risk: If health issues develop before you apply, high blood pressure, weight gain, diabetes diagnosis, you'll face loadings or exclusions. Apply while you're healthy.
2. Quit Smoking (After 12 Months)
If you smoke, quitting is the single biggest cost-reduction opportunity available. After 12 months smoke-free, you can request reclassification as a non-smoker. The savings are substantial.
Most insurers just need a statutory declaration, though they may ask for medical evidence (blood test). The reduction is effective immediately.
3. Get Healthy Before Applying
New applications are underwritten based on your current health, unlike existing policies. You can strategically improve health before applying:
Weight loss: Moving from BMI 35 to 29 could reduce premiums by 30-50%
Blood pressure control: Get hypertension under control before applying
Timing: Apply before scheduled surgery if possible (post-surgery, you'll face loadings)
4. Compare Multiple Insurers
Premium variation between insurers for identical coverage is 20-30%+. Don't accept the first quote. Our comparison tool shows you side-by-side pricing from 9 panel insurers (AIA, Zurich, TAL, OnePath, ClearView, NEOS, Encompass, Acenda, and Futura).
5. Choose Stepped Premiums If You Don't Need Long-Term Coverage
If you plan to stop coverage in 10-15 years (when kids are independent and mortgage is paid), stepped premiums cost significantly less total. You won't keep it long enough for the compounding to catch up.
6. Bundle Coverage Types
Buying life, TPD, trauma together typically saves 15-25% compared to separate policies. But only buy what you need, the savings don't justify unnecessary cover.
Key Insights About Lifetime Costs
Your First 15 Years Matter Most
Due to how costs compound (doubling every 7-10 years), the first 15 years of a policy are incredibly important. This is why buying at 30 instead of 40 saves so much, you lock in a decade and a half of lower rates.
The compounding effect (Source: LRO API panel data, indicative range, male non-smoker, $500k cover):
Age 35:
Age 45: (moderate increase)
Age 50: (accelerating)
Age 55: (substantial increase)
Age 60: (steep compounding)
The acceleration after 50 reflects the rapid increase in health conditions at those ages.
The later decades cost far more cumulatively. This is why delaying even 5 years (indicative) can cost you tens of thousands over a 30-year policy.
What About After 65?
Many people wonder if they should keep coverage in retirement. The honest answer: it depends on your goals.
You can drop it if:
Your mortgage is paid
Your kids are independent and self-supporting
You have accumulated assets to leave as inheritance
You can't afford the high costs (premiums jump dramatically after 65)
You might keep it if:
You want to leave money to children or grandchildren
You want to cover funeral costs without burdening family
You have a younger spouse who depends on your income
You want to leave money to charity
You need liquidity for estate costs
Strategic approach: Many advisers recommend reviewing at retirement and reducing coverage to modest amounts ($100-200k) to cover specific goals like funeral costs and a small inheritance, rather than maintaining full coverage at very high cost.
Don't Buy on Price Alone
The cheapest premium is meaningless if claims are denied when you need them. Here's what actually matters:
Compare Policy Features, Not Just Price
Terminal illness benefit: Check if it's 12 months or 24 months. The difference can matter significantly for some conditions. A 24-month definition is more valuable and typically costs 3-5% extra.
TPD definitions: Own Occupation (pays if you can't do your specific job) is better than Any Occupation (pays only if you can't do any job). Worth paying 10-20% more for Own Occupation if you have a specialized career.
Trauma coverage: More conditions aren't always better, focus on how conditions are defined. A policy with 50 well-defined conditions is better than 70 loosely-defined ones.
Check Insurer Reputation
Research actual claims performance:
Claims acceptance rates: Varies from 92-98% across insurers (APRA data shows this variation)
Processing time: 30 days vs 90 days is a big difference when you need money
Customer reviews: Look for patterns in complaints
A 10-15% premium difference is worth paying if it means higher claim acceptance and faster service.
Frequently Asked Questions
Why do life insurance premiums increase with age?
Life insurance premiums are based on mortality risk, the statistical likelihood that the insurer will need to pay a claim. As we age, mortality risk increases exponentially, not linearly. A 60-year-old is statistically much more likely to die in the next year than a 30-year-old.
Insurers use Australian Life Tables published by the Australian Government Actuary, which compile national death statistics by age and gender. These tables show that mortality rates roughly double every 7-10 years, which is why you see stepped premiums increasing by 7-10% annually, they're compounding to match the exponential mortality curve.
The acceleration after age 50 reflects the rapid increase in age-related health conditions: cardiovascular disease, cancer, and other chronic conditions become significantly more common in your 50s and 60s.
Is life insurance more expensive for women?
No, women consistently pay 20-40% less than men for life insurance at all ages. This is based on mortality statistics showing women have longer life expectancy and lower mortality rates at every age bracket.
According to the Australian Bureau of Statistics, female life expectancy at birth is 85.4 years compared to 81.6 years for males (a 3.8-year difference). More importantly for insurance pricing, women have lower mortality rates at every single age from 25 to 85.
This isn't discrimination, it's actuarially-based pricing reflecting real statistical differences. The same principle means women often pay more for trauma insurance (because they're more likely to survive a critical illness) while paying less for life and TPD cover.
How much does smoking affect life insurance cost?
Smoking increases life insurance premiums by 50-100%, depending on your age:
Ages 25-35: Smoking typically 1.8-2.2x the base rate (80-120% increase)
Ages 35-50: Smoking typically 1.6-2.0x the base rate (60-100% increase)
Ages 50+: Smoking typically 1.5-1.8x the base rate (50-80% increase)
You're classified as a smoker if you've used any tobacco or nicotine-containing products in the past 12 months, including cigarettes, cigars, pipes, vaping with nicotine, or nicotine replacement therapy beyond the first 3 months of quitting.
The good news: you can be reclassified as a non-smoker after 12 months smoke-free. Contact your insurer, complete a declaration, and they may request medical evidence (blood test for cotinine). The premium reduction is immediate and permanent as long as you remain smoke-free.
The financial incentive is substantial, combined with obvious health benefits, quitting smoking is one of the most economically rewarding health decisions you can make in terms of insurance costs.
Can I lock in my premium rate forever?
Level premium structures lock in your rate for an extended period, typically to age 65, 70, or 75, but not forever. After the level period ends, premiums convert to stepped rates at your then-current age.
This conversion can be jarring. current panel data shows a 60-year-old male non-smoker already pays a premium within the indicative panel range for $500,000 cover on stepped premiums (Source: LRO API panel data, indicative range), someone converting from level premiums at 65 faces stepped rates for a 65-year-old, which will be higher still. Many people cancel policies at conversion, which is unfortunate if they still need coverage.
Some insurers offer "guaranteed premium rates" that lock in premiums for life, but these are typically 80-100% more expensive than standard level premiums and are rarely cost-effective. The math only works if you're certain you'll maintain coverage until death and you value premium certainty very highly.
Best strategy: Choose level premiums if you plan to keep coverage for 20+ years and understand the conversion that happens at the end of the level period. Plan your coverage to end around retirement (when financial dependents are typically independent and mortgages are paid), avoiding the high costs of post-65 insurance.
