If you’re thinking about an IUL, the smartest thing you can do before you sign anything is ask better questions. An IUL — short for indexed universal life — can be a powerful tool for tax-advantaged growth and protection, but only when it’s built correctly. I’ve seen policies that were designed to serve the family, and I’ve seen policies that were designed to serve the commission. The difference almost always comes down to the questions the client asked (or didn’t ask) up front.

As a dad raising two boys here in South Florida, I don’t take financial decisions lightly, and I don’t want you to either. So here are the five questions I’d want you to ask any agent — including me — before you buy an IUL.

1. Is this IUL designed for maximum death benefit or maximum cash value?

This is the most important question, and most people never ask it. The same product can be structured two completely different ways. If it’s built for a large death benefit, more of your premium goes toward the cost of insurance, and your cash value grows slowly. If it’s built for cash value accumulation, the death benefit is set as low as the IRS rules allow and more of your money goes to work for you.

Neither approach is wrong — it depends on your goal. But you deserve to know which one you’re buying. A properly structured IUL is intentionally designed around your objective, whether that’s protection, tax-advantaged growth, or supplemental retirement income.

2. How much am I funding it, and what happens if I underfund it?

An IUL is not a “set it and forget it” product. It’s a living contract that depends on being funded properly. Overfunding it (up to the IRS limit) is usually the goal for cash value, because it maximizes growth and minimizes the drag from insurance costs. Underfunding it is where policies get into trouble.

Ask your agent to show you what happens if you skip payments or pay the bare minimum. Ask them to run the illustration at a conservative rate, not just the rosy one. If the policy only “works” when everything goes perfectly, that’s a red flag worth taking seriously.

A quick word on illustrations

Illustrations are hypothetical. They are not guarantees, and no one can promise you a specific rate of return. When an agent shows you a number, ask them to also show you the guaranteed column and a mid-range assumption. Real families need to plan for the middle, not the best case.

3. What is the cap, the floor, and the participation rate?

These three numbers control how your money grows. The floor is your downside protection — in most IULs it’s zero, meaning a negative market year credits you 0% instead of a loss. The cap is the most you can be credited in a good year. The participation rate is the percentage of the index’s gain you actually receive.

The zero floor is the feature people fall in love with, and for good reason: not losing money in a down market is a real advantage. But you should understand the trade-off. In exchange for that protection, your upside is limited by the cap. Ask what the current cap is, whether the company can change it, and how it has behaved historically. Understanding these levers is the difference between owning the policy and being surprised by it.

4. What are the fees, and when do the surrender charges end?

Every IUL has costs — the cost of insurance, administrative fees, and potential rider charges. That’s normal; it’s insurance. What matters is whether those costs are reasonable for what you’re getting, and whether they’re front-loaded in a way that hurts you if your situation changes.

Pay special attention to the surrender charge schedule. Most IULs carry a surrender period of roughly 10 to 15 years, during which pulling money out early can cost you. That’s not necessarily bad — this is a long-term vehicle — but you need to know the timeline before you commit, so you’re never forced to choose between a penalty and an emergency.

5. How does accessing my money actually work — and is it really tax-free?

One of the biggest appeals of a well-funded IUL is the ability to access cash value through policy loans that, when structured correctly, can be taken income-tax-free under current tax law. That can make it a valuable piece of a tax-free retirement income strategy.

But “tax-free” comes with rules. Loans reduce your death benefit if they aren’t repaid, and a policy that lapses with a large outstanding loan can trigger a tax bill. This is where design and ongoing management matter enormously. Ask your agent to walk you through exactly how you’d take income in retirement and what safeguards keep the policy healthy while you do. If they can’t explain it simply, keep asking until they can.

The bottom line

An IUL can be one of the most flexible tools in a financial plan — protection for your family, growth with a zero floor, and tax-advantaged access to your money later in life. But it is only as good as the way it’s built and the honesty of the person who builds it. Ask these five questions, insist on clear answers, and you’ll be able to tell very quickly whether a policy was designed for you or for someone else.

Frequently asked questions

Is an IUL a good investment?

An IUL is technically life insurance with a cash value component, not a direct investment in the market. For the right person — someone who wants protection plus tax-advantaged growth with downside protection and can fund it consistently — it can be a strong fit. For someone who wants the lowest-cost death benefit or maximum market upside, other tools may fit better. It depends on your goals.

What is the “zero floor” in an IUL?

The zero floor means that in a year when the index it tracks goes down, your credited interest is 0% rather than a loss. You don’t participate in the market’s declines. In exchange, your gains in strong years are limited by a cap. It’s a trade of some upside for meaningful downside protection.

Can I lose money in an IUL?

Your indexed account generally won’t lose value from market drops because of the floor, but the policy still has internal costs like the cost of insurance and fees, which can erode cash value if the policy is underfunded. That’s exactly why proper design and adequate funding matter so much.
