One question drives every IUL conversation: what does it actually pay out? These three carrier illustrations answer it across three different starting points — a mid-career professional at 45, a 40-year-old starting early, and a child at age 8. Same structure, very different results.
Case Study #1: Male, Age 45 - Mid-Career Professional
Profile: Male, 45, Preferred Plus Nontobacco | Initial Death Benefit: $357,459
💰Money In(Ages 45–65)
💵Money Out(Ages 65–95)
🎁Legacy Left(At age 95)
💸Taxes Saved
This mid-career professional commits $25,000 annually for 20 years, building substantial retirement income while maintaining life insurance protection. By age 65, his death benefit reaches $1.36 million - 2.7 times what he paid in premiums - while his cash value stands at $1.08 million.
The real power shows up in retirement. From ages 65 to 95, he receives $92,790 per year tax-free - that's over $7,700 monthly in income he'll never pay taxes on. After taking out $2.78 million over 30 years, he still leaves nearly $500,000 to his heirs.
Key Insight: His family was protected by a substantial death benefit for 20 years during his peak earning years, while he simultaneously built a tax-free retirement income stream. If he died at 65 before taking distributions, his family would receive $1.36 million tax-free.
📊Tax-Free vs. Taxable Withdrawal
All figures above come from one carrier illustration for this profile and funding schedule — projected values, not guaranteed. The tax comparison uses 2025 federal brackets for a single filer with the standard deduction applied to that illustrated income (not tax advice). To clear the same spendable income from a pre-tax retirement account, he would withdraw about $108,210 per year — roughly $15,420 of that withdrawal goes to federal income tax that he avoids with tax-free policy loans.
Case Study #2: Female, Age 40 - Early Start Advantage
Profile: Female, 40, Preferred Plus Nontobacco | Initial Death Benefit: $172,662
💰Money In(Ages 40–65)
💵Money Out(Ages 65–95)
🎁Legacy Left(At age 95)
💸Taxes Saved
Starting five years earlier with a more modest premium commitment, this professional commits $9,000 annually for 25 years. The lower annual premium combined with extra accumulation time creates impressive results - an 8.0x return multiple compared to the 6.5x in Case Study #1.
By age 65, she has a $719,000 death benefit and $546,000 in cash value. Her retirement income of $50,802 annually for 30 years illustrates a LIRP-style distribution plan — over $4,200 per month that never gets taxed.
Key Insight: Women typically receive better rates on life insurance due to longer life expectancy. Combined with starting at age 40 (five years earlier than Case #1), the additional accumulation time significantly boosts the return multiple despite lower annual premiums.
📊Tax-Free vs. Taxable Withdrawal
All figures above come from one carrier illustration for this profile and funding schedule — projected values, not guaranteed. The tax comparison uses 2025 federal brackets for a single filer with the standard deduction applied to that illustrated income (not tax advice). To match the same net spendable income from a pre-tax account, she would withdraw about $55,413 per year — about $4,611 of federal income tax per year avoided with tax-free policy loans.
Case Study #3: Male, Age 8 - The Power of Time
Profile: Male, 8, Juvenile | Initial Death Benefit: $118,231
💰Money In(Ages 8–65)
💵Money Out(Ages 65–95)
🎁Legacy Left(At age 95)
💸Taxes Saved
This case study demonstrates why time is the most powerful variable in IUL performance. With just $3,420 per year - less than $300 monthly - this policy creates extraordinary wealth through 58 years of compound growth.
By age 65, this policy has a death benefit of $2.9 million and cash value of $2.38 million from total premiums of just $198,360. The annual retirement income of $210,366 provides over $17,500 monthly tax-free for 30 years.
The total value delivered exceeds $7.4 million - a remarkable 37.3x return on premiums paid. Even after withdrawing $6.3 million in retirement income, over $1 million remains as a death benefit for heirs.
Key Insight: Starting at age 8 allows compound growth to work for 58 years before retirement. The modest annual premium of $3,420 becomes manageable for parents planning their child's financial future, while the extended time horizon creates returns that dwarf what's possible when starting later in life.
📊Tax-Free vs. Taxable Withdrawal
All figures above come from one carrier illustration for this profile and funding schedule — projected values, not guaranteed. The tax comparison uses 2025 federal brackets for a single filer with the standard deduction applied to that illustrated income (not tax advice). To match the same net spendable income from a pre-tax account, he would withdraw about $268,713 per year — about $58,347 of federal income tax per year avoided with tax-free policy loans.
Expert Insight: Age changes everything
Starting at 8 beats starting at 45 by a 37x vs 6.5x margin. Every decade earlier you fund an IUL, the return multiple roughly doubles — because compound growth needs runway, not just dollars.

Key Comparison Insights
Premium Flexibility: These cases show IUL works across different income levels. The $3,420 annual premium for a child, $9,000 for moderate income professionals, and $25,000 for high earners all create substantial value - just at different scales.
Age Advantage: Starting at age 8 produces a 37.3x return versus 6.5x when starting at 45. The additional decades of compound growth create exponential differences in outcomes. Even the five-year head start from age 40 to 45 improves returns from 6.5x to 8.0x.
Gender Differences: Female rates typically offer 10-15% better pricing than male rates at equivalent ages and health ratings due to longer life expectancy. This advantage shows clearly when comparing the age 40 female (8.0x return) to what a male at the same age would receive.
Common Thread: All three cases deliver substantial tax-free retirement income while maintaining death benefit protection. Whether receiving $50,802 or $210,366 annually, none of this income is taxable - a massive advantage over 401(k) distributions that face ordinary income tax rates.
Is This Strategy Right for You?
Most people approach IUL as an investment and ask the wrong question: "What's the return?" The better question is: "Where is your money now, and what does that pocket cost you?"
Every dollar sitting in a brokerage account, a savings account, or a 401(k) has a tax exposure attached to it — now or later. An IUL doesn't try to beat the market. It moves money from the taxable pocket to a pocket that's liquid, protected from loss, insured, and tax-free when you take it out. That's the whole idea.
If your goal is tax-free retirement income, the case studies above apply directly. Time is the accelerant — the longer your runway, the larger the multiple. Starting at 40 instead of 45 meaningfully changes the outcome, and starting at 8 changes everything.
If your goal is storage and safety, time matters far less. You're not optimizing for a 37x multiple — you're moving money somewhere that grows without market risk, stays accessible, carries a death benefit, and comes out tax-free. A 55-year-old can fund an IUL for that purpose today. There's no minimum runway for storing money safely.
The people this doesn't fit: those in poor health where insurance costs eat into the value, those who need money fully liquid in under two or three years, or those who want maximum market upside without a floor.
Conclusion
Think of it this way: you have two pockets. One is taxable — brokerage accounts, pre-tax retirement accounts, savings earning interest you'll report. The other isn't. A properly structured IUL is a way to move money from the first pocket to the second. The money still belongs to you. You can still access it. It still grows. But the tax exposure goes away.
The case studies above show what that looks like when the goal is retirement income. The multiples — 6.5x, 8x, 37x — are what happens when you add time. But even without decades of runway, the core value is the same: protection, liquidity, safety, and a tax-free legacy. Those don't require 15 years to work.
What changes by carrier is policy design — loan structure, crediting strategy, cost of insurance, how the cash value compounds. Two policies funded identically can produce meaningfully different results at age 65. That's what an independent agent comparison actually does: it finds the design that fits your goal, not the one that pays the highest commission.
