Top 5 Mistakes People Make When Buying an IUL

Common design mistakes can impact cash value growth, living benefits, and long-term flexibility.

4/16/2026

Indexed Universal Life insurance (IUL) can be a flexible tool for both protection and cash value accumulation. However, the way a policy is designed, funded, and managed can dramatically affect how well it performs for you. Over the years, Lenhoff Financial has observed several common IUL mistakes that can limit cash value growth, compromise living benefits, and reduce long-term flexibility. If you're considering an IUL or reviewing your current policy, understanding these pitfalls can help you make a more informed decision.

Underfunding or Overfunding the Policy

Setting up your IUL’s premium schedule is not as simple as picking a number that “fits the budget.” One of the most frequent Indexed Universal Life mistakes is underfunding—paying the minimum premium required to keep the policy active. While it keeps costs down in the short term, underfunding can prevent your cash value from accumulating, restrict options for loans or withdrawals, and may even jeopardize the policy’s long-term viability as costs increase with age.

Conversely, overfunding—paying much more than needed—can maximize IUL cash value growth, but only if managed carefully to stay within IRS guidelines and avoid MEC (Modified Endowment Contract) status. The right funding strategy depends on your personal objectives, age, income, and risk tolerance. This is where the expertise of an independent broker like Lenhoff Financial can be invaluable, allowing you to compare multiple carriers and funding designs tailored to your situation.

Choosing the Wrong Death Benefit Option or Amount

The structure of your death benefit directly impacts cost and performance. Selecting an unnecessarily large death benefit, for example, drives up insurance charges and leaves less premium available to accumulate cash value. On the other hand, opting for the lowest possible death benefit could limit the living benefits and flexibility your policy offers in the long run. An experienced independent broker can help weigh your protection needs against long-term growth goals, ensuring the policy is properly structured for your objectives—not just for a short-term illustration.

Relying on Unrealistic Policy Illustrations

IUL cash value projections are just that—projections. All illustrations are hypothetical and based on assumptions about index performance, crediting rates, fees, and policyholder behavior. Too often, buyers place too much trust in these optimistic scenarios. Market fluctuations, changes in caps, or withdrawing funds earlier than anticipated can alter actual results. Lenhoff Financial encourages clients to review a range of illustration scenarios, including conservative ones, and to revisit the policy regularly as circumstances change.

Working with a Captive Agent Instead of an Independent Broker

Where you purchase your IUL is as critical as how you fund it. Captive agents typically represent a single carrier, which may limit your options in policy structure, riders, or pricing. An independent brokerage like Lenhoff Financial acts on your behalf, comparing multiple carriers and product designs so you receive a solution aligned with your values, objectives, and budget. This flexibility is especially important with IULs, which can vary widely in fees, crediting strategies, and contract features between companies.

Ignoring Policy Reviews and Ongoing Management

Indexed Universal Life is not a “set it and forget it” product. Market conditions change, carrier rates can fluctuate, and your own needs may evolve. Failing to consistently review your IUL can result in missed opportunities, underperforming cash value, or policies lapsing unexpectedly due to increasing internal costs. A periodic review with a licensed broker helps ensure your policy stays on track and gives you a chance to adapt if your goals shift.

Choosing the Right Path Forward

Buying an IUL is a significant financial decision, and getting the design right from the start can make all the difference. By avoiding these common IUL mistakes—improper funding, mismatched death benefits, reliance on overly optimistic illustrations, working with a limited agent, and neglecting reviews—you are setting the stage for better cash value growth and policy flexibility.
