Why IUL Is a Bad Investment (Hidden Fees & Risks)

I remember sitting across from a guy named Mark at a Panera in Phoenix back in 2019. He was friendly, drove a nice car, and kept using the phrase “tax-free retirement” like it was some kind of magic spell. He was selling me on an Indexed Universal Life policy—IUL for short—and by the end of our conversation, I almost felt stupid for not having bought one years earlier.

Almost.

Something about it kept nagging at me. The math felt… fuzzy. And over the next few weeks, as I dug into the fine print (the actual fine print, not the glossy brochure), I started realizing why my gut was sending up red flags.

Now, I’m not here to tell you what to do with your money. I’m just a guy who’s spent a lot of years watching how these things play out for regular people—teachers, electricians, people who work in HR, folks who just want to make sure they’re not eating cat food in retirement. And from where I sit, IUL is one of those products that sounds a whole lot better in a sales pitch than it performs in real life.

Let me walk you through what I’ve seen.

The Sales Pitch Sounds Incredible Why IUL Is a Bad Investment

You’ve probably heard the pitch. Maybe it came from a cousin who just got licensed to sell insurance, or a “financial advisor” who actually works for an insurance company. They’ll tell you that an IUL gives you the best of both worlds: life insurance protection plus a cash value account that grows with the stock market. But here’s the kicker—you don’t actually lose money when the market drops. Zero downside. Participation in the upside, protection on the downside. Who wouldn’t want that, right?

The way they explain it, the insurance company takes your premiums, puts some into a cash value bucket, and that bucket’s growth is tied to an index like the S&P 500. If the index goes up, you get credited interest—up to a cap, usually somewhere between 10% and 12%. If the index goes down, you get zero. Not negative. Just zero.

Sounds like a free lunch.

But here’s something nobody told me at that Panera: there’s no such thing as a free lunch in finance. Ever. If it sounds like you’re getting market-like returns without the risk, there’s always a catch. Usually several.

The Participation Rate That Nobody Explains Why IUL Is a Bad Investment

Let me tell you about something called a participation rate. I didn’t know this existed until I pulled out my calculator and started questioning everything.

When you buy an IUL, you’re not actually invested in the stock market. The insurance company is just using an index to decide how much interest to credit to your policy. But that interest isn’t the full return of the index. You might only get 80% of the index’s gain. Or 70%. Or sometimes they change it year to year.

So let’s say the S&P 500 goes up 20% in a year (which does happen). If your policy has a 10% cap and an 80% participation rate, you’re not getting 10%. You’re getting 8%. Actually, wait—let me run that math again because even I get tripped up. They apply the participation rate first. So 20% times 80% is 16%, but then the cap cuts you off at 10%. So you get 10%. Not the full index return. Not even close.

Now, if the market goes up 6% in a year, you might get 4.8% after the participation rate, assuming there’s no floor that kicks in at a lower number. And if the market goes up 30%? Still 10% for you. But if the market goes down 15%? You get zero.

That’s not “upside without downside.” That’s upside with a ceiling and downside with a floor that’s zero. Over time, that math doesn’t work out in your favor the way the brochures suggest.

Fees Are Everywhere (And They Move) Why IUL Is a Bad Investment

Another thing I learned the hard way—well, not the hard way because I didn’t actually buy one, but I learned it by staring at policy illustrations until my eyes crossed—is that these things have fees layered on top of fees.

There’s the cost of insurance, which goes up as you get older. That’s true for any life insurance, but with IUL, those costs get deducted from your cash value. Then there are administrative fees. Then there are charges for the riders—you know, the “extras” they sell you like guaranteed insurability or long-term care access. Then there’s something called a surrender charge, which is basically a penalty if you try to get out of the policy in the first 10 or 15 years.

And here’s the part that really got me: the insurance company can change some of these fees. Not all of them, but enough that the illustration they showed you in year one might not reflect what actually happens in year ten.

I’m not saying they’re being sneaky. I’m saying the contract gives them flexibility, and flexibility usually benefits the company, not the customer.

The “Tax-Free” Part Is Real, But… Why IUL Is a Bad Investment

Okay, let’s give credit where it’s due. The tax treatment on IUL policies is legit. The cash value grows tax-deferred, and if the policy is structured correctly, you can take loans against the cash value tax-free in retirement. That’s not a gimmick. That’s the actual tax code.

But here’s what the salesperson might not emphasize: those loans aren’t free. The insurance company charges interest on them, typically between 4% and 8%. And if the policy lapses—meaning you stop paying premiums or the cash value drops too low—the IRS can treat all those “tax-free” loans as taxable income. In one year. All at once.

I’ve heard stories from people who thought they had this beautiful tax-free retirement income stream set up, then something went sideways—they couldn’t afford the premiums anymore, or the policy underperformed—and they ended up with a tax bill they never saw coming.

Is that likely to happen if you fund the policy perfectly and never miss a payment? Probably not. But life doesn’t always cooperate with “perfectly fund and never miss a payment.” People lose jobs. People get sick. People have kids and realize they overextended on premiums.

What the Illustrations Don’t Show You Why IUL Is a Bad Investment

If you’ve ever seen an IUL illustration, you know they’re beautiful pieces of paper. Columns of numbers showing cash value growing year after year, hitting six figures, then seven, then this beautiful “retirement income” stream that lasts until age 100.

What they don’t show you is what happens if the market has a string of flat years. Or what happens if the insurance company raises the cost of insurance. Or what happens if you take that loan out and the market drops right after, causing your cash value to dip below what you owe.

I remember looking at one illustration where the policy was projected to have $450,000 in cash value by age 65, assuming a 7% average return on the index. Then I looked at the guaranteed column—the one that shows what happens if the market does nothing—and it showed $0. Actually, it showed that the policy would lapse by age 75 if returns were at the guaranteed minimum.

That gap between the “illustrated” scenario and the “guaranteed” scenario is enormous. And I’m not saying you should assume the worst-case scenario. But you should at least know how wide the gap is.

Why I Think People Buy These Anyway

I’ve thought a lot about why IULs have become so popular, especially with people in their 30s and 40s who are smart, successful, and usually pretty skeptical about financial products.

I think it comes down to two things.

First, fear of the stock market. After 2008, a lot of people just don’t trust that their 401(k) will be there when they need it. The idea of “market protection” is incredibly appealing. If you can grow your money without the risk of losing it, why wouldn’t you?

Second, the allure of “doing something special” with your money. There’s a certain type of person—and I’ve been this person before—who doesn’t want to just put money in a boring old IRA or 401(k). That feels too ordinary. An IUL feels sophisticated. It feels like you’ve found a secret that most people don’t know about.

But here’s what I’ve learned over the years: the boring stuff usually works. Maxing out a 401(k) match, contributing to a Roth IRA, keeping an emergency fund in a high-yield savings account—none of that is exciting, but none of it comes with hidden fees or participation rates or surrender charges.

Who Actually Benefits From an IUL? Why IUL Is a Bad Investment

I want to be fair here because I know people who own IULs and genuinely believe they’re a good fit for their situation. And for a very small slice of people, maybe they are.

If you’re already maxing out your 401(k), maxing out your IRA, have a paid-off house, and need a place to park additional money for estate planning purposes—like you have enough assets that estate taxes are a real concern—then an IUL might make sense as a piece of a larger plan. But even then, I’d want to look at it from ten different angles before signing anything.

For the other 98% of people? The ones who still have student loans, or a mortgage, or haven’t yet hit their 401(k) match? I just don’t see the math working.

What I’d Do Instead Why IUL Is a Bad Investment

If you’re someone who’s been pitched an IUL and you’re trying to figure out what to do, here’s what I’d suggest—not advice, just what I’d personally do if I were in your shoes.

I’d ask myself: do I actually need life insurance? If you have people who depend on your income—kids, a spouse, aging parents—then term life insurance is probably the move. It’s straightforward, it’s cheap, and it does exactly what it’s supposed to do. A 20- or 30-year term policy for $1 million might cost you $50 to $100 a month, depending on your age and health. That’s it. No complexity.

Then, separately, I’d focus on investing. Not through an insurance product, but through tax-advantaged accounts that were designed for that purpose. A Roth IRA is hard to beat for tax-free growth. A 401(k) with an employer match is literally free money. Even a simple taxable brokerage account gives you more control, lower fees, and no insurance company middleman.

The separation matters. When you mix insurance and investing, you end up with something that’s mediocre at both.

A Question I Still Think About

I’ll leave you with something that’s stuck with me since that conversation with Mark.

I asked him: if this product is so great for building wealth, why don’t we see wealthy people buying them? Like, why aren’t Warren Buffett or the partners at Goldman Sachs loading up on IULs?

He had an answer, of course. Something about how wealthy people don’t need the tax benefits, or how they have other strategies. But the more I’ve thought about it over the years, the more I’ve realized something: if a financial product is primarily sold by insurance agents (who earn hefty commissions) rather than bought by sophisticated investors, there’s probably a reason for that.

I’m not saying it’s a scam. It’s not. It’s a legal, regulated product that serves a purpose for certain situations. But for most people, it’s a solution in search of a problem—and a pretty expensive one at that.
