What if one of the most expensive investments in your retirement plan isn't actually an investment at all?
That's the question worth asking when life insurance is presented as a retirement savings strategy.
Indexed Universal Life insurance, or IUL, is often marketed as a way to accomplish several financial goals at once: protect your family, accumulate wealth, participate in stock market gains without directly experiencing market losses, and eventually generate tax-advantaged retirement income.
It sounds like an appealing combination.
But before committing tens of thousands of dollars to a life insurance policy, there's a more fundamental question worth considering:
Would you be better off separating your life insurance from your retirement investments?
One Product, Two Very Different Objectives
Life insurance and retirement savings serve different purposes.
Life insurance is primarily designed to provide financial protection if you die. Retirement investments are intended to accumulate wealth you can eventually use during your lifetime.
An IUL attempts to accomplish both through one contract.
Part of the premium supports life insurance coverage and policy expenses. The policy also builds cash value that can earn interest linked to the performance of a market index, subject to caps, participation rates, and other contractual provisions.
Properly structured, that cash value may eventually be accessed through withdrawals and policy loans, potentially providing tax-advantaged retirement cash flow.
Those benefits can be valuable.
But combining insurance and investing doesn't automatically make either objective more efficient.
What Does the Math Actually Look Like?
Consider a 40-year-old professional with a spouse, two children, and approximately $20,000 annually available for long-term financial planning.
An insurance agent recommends an Indexed Universal Life policy. The appeal is straightforward: $1 million in life insurance protection, cash-value accumulation, and the potential to use that cash value for retirement.
But what does the policy actually accumulate?
A June 2026 illustration for a North American indexed universal life policy provides a useful example. For a healthy 40-year-old male paying approximately $19,400 annually, the policy projects several possible outcomes after 20 years.
Under its more favorable non-guaranteed assumptions, the policy shows approximately $597,000 in cash surrender value.
Under a lower 4.5% index-crediting scenario, that figure falls to approximately $469,000. Under the policy's guaranteed minimum assumptions and maximum charges, the illustrated value is approximately $299,000.
Those are dramatically different outcomes from the same premium commitment.
Now consider an alternative.
Our investor purchases a hypothetical 20-year, $1 million term life insurance policy for $1,200 annually, then invests the remaining $18,200 each year in a diversified portfolio.
Assuming a hypothetical 6% annual return, that portfolio could accumulate approximately $670,000 after 20 years, before investment taxes and expenses.
That's about $73,000 more than the IUL's favorable illustrated cash surrender value—and substantially more than its less favorable scenarios.
Of course, this isn't a perfect apples-to-apples comparison. The investment portfolio faces market risk and taxes, while the IUL includes permanent death benefit protection and potentially valuable tax advantages. Those differences matter, and neither outcome is guaranteed.
But the comparison illustrates an important point:
Combining life insurance and retirement savings doesn't automatically produce a better financial outcome.
If retirement accumulation is your primary goal, the IUL's additional benefits need to justify their costs. And that requires evaluating the actual numbers, not simply accepting an attractive illustration of future retirement income.
The Costs Aren't Always Obvious
An IUL isn't simply an investment account with life insurance attached.
Premiums support several expenses, potentially including administrative charges, premium loads, and the ongoing cost of insurance. Some policies also impose substantial surrender charges if the owner wants to exit during the early years.
And unlike term insurance, the cost of insurance protection inside a universal life policy can increase as the insured gets older.
That matters because even when an IUL's index-crediting strategy has a 0% floor, policy charges can still reduce cash value.
There's also the question of flexibility.
Money invested in a conventional brokerage account can generally be accessed without surrender penalties, although selling investments may trigger taxes or losses.
Accessing IUL cash value can be more complicated. Withdrawals may reduce policy benefits, while loans accrue interest and can create serious tax consequences if the policy eventually lapses.
None of these considerations automatically makes an IUL inappropriate. But they deserve attention before treating the policy as a retirement investment.
When Permanent Life Insurance Makes Sense
Term insurance eventually expires. An appropriately funded permanent life insurance policy may provide coverage for life, subject to its terms and continued financial performance.
For families with lifelong insurance needs, estate liquidity concerns, business succession obligations, or other specialized planning objectives, that distinction can be extremely valuable.
An IUL may also offer tax advantages that a conventional taxable investment account does not.
Those benefits have real economic value and deserve to be evaluated alongside the policy's costs.
But that's precisely the point.
If permanent life insurance solves an important financial planning problem, it may justify its expense.
If the primary goal is retirement accumulation, however, the policy should be compared against other ways to build retirement wealth, not simply accepted because an illustration shows an attractive future income stream.
Start With the Goal, Not the Product
At Hanover Advisors, we believe financial planning should begin with the problem you're trying to solve, not the product someone wants to sell you.
Perhaps you need lifetime insurance protection. Perhaps you need tax-efficient retirement savings. Perhaps you need both.
But needing both doesn't necessarily mean purchasing them together is the best solution.
Before committing significant retirement savings to an IUL, understand the insurance costs, projected and guaranteed values, liquidity restrictions, tax implications, and realistic alternatives.
Because the goal isn't to find a financial product that promises to do everything.
It's to build a financial plan in which every dollar has a clear purpose—and every cost has a reason.
