Should you buy an Index Universal Life policy or invest directly or invest in the S&P 500? This conversation keeps coming up more and more — especially right now — because IULs are being pushed hard as an “investment solution,” particularly to communities that are trying to build wealth for the first time.

An Index Universal Life policy, or IUL, is a life insurance product that’s tied to a particular market index such as the S&P 500, Dow 30, or Nasdaq 100. Insurance companies can even basket a selection of stocks to create their own “index” and sell insurance product tied to it. An IUL IS NOT AN INVESTMENT! This is important to not because insurance agents are promoting it as such. This comparison will evaluate it the IUL as an “investment” so you can see why someone could be fooled into thinking it is an investment.

The biggest draw to an IUL is simple: you don’t lose money. That’s the hook. That’s the emotional trigger. People understand that the fear of losing is stronger than the desire to win, and that’s exactly how these products are marketed.

For example -If you buy an IUL with a 10.5% cap:

This sounds great at first, but here’s the part most people never stop to think through: what are you giving up in exchange for that protection?

I compared the last 15 years of real S&P 500 returns to an IUL capped at about 10.5%, which is a cap I’ve actually seen being marketed recently. This comparison looks at IUL as an “investment” since it can be marketed that way.

When you invest directly in the S&P 500, you’re going to experience some down years. That’s just reality. Over this 15-year stretch, there were a handful of negative returns. But the other years presented strong gains. Some years were much higher than market averages and in the double digits. For that 15-year period, that compounding pushed the average annual return to around 12.8%.

Now let’s look at the IUL.

Every time the market did 13%, 20%, or even close to 30%, the IUL investor was capped at 10.5%. Yes, when the market went negative, they didn’t lose anything — they sat at 0% gain with no loss. That sounds great on the surface. But when you zoom out and look at the full 15-year period, the capped growth changed everything.

Instead of ending around 12.8%, the IUL landed closer to 7.6% annually — and that’s before you even talk about fees.

That extra 5.22% annual return went straight into the insurance company’s pocket. My friends, this is why these products are pushed so aggressively. If the market returns 29% and you’re capped at 10.5%, that gap doesn’t vanish — it becomes profit.

Think about that. A 5.22% return on your own money, every year, going to the insurance company instead of your portfolio, simply because you agreed to limit your upside.

Now, I understand why the “no losses” feature sounds appealing. People are scared of volatility. They’ve seen downturns, heard horror stories, and they want something that feels safe. But investing has never been about avoiding every loss. It’s about understanding what you gain and what you give up.

Markets don’t move in straight lines. Some years will be negative. But historically, the years of strong growth more than make up for those losses — if you’re allowed to capture the upside. When you cap that upside, you limit the very compounding that builds long-term wealth.

Building wealth in the market is actually simple. IULs present a log of complexity that can work against you. IULs are incredibly technical products. Some aren’t even indexed to the S&P 500 or the Russell — they use custom-built indexes that most people have never heard of. Caps can change. Fees can change. Even the index itself can change depending on market conditions. Meanwhile, a simple index fund is transparent. You know what you own. You know what you’re paying.

This is why I always tell people that financial literacy isn’t just knowing what a product is — it’s being able to think through the scenario. What am I gaining? What am I losing? And why is this product being pushed to me?

Now, I’ll be fair here. One valid concern people have is sequence of return risk. That’s the fear of the market dropping right before or right after you retire. Some people see IULs as a way to avoid that risk. But you don’t need to hand over five percent of your portfolio every year to manage it.

A smart adviser will tell you to start de-risking as you approach retirement. Move some money into bonds, high-yield savings, or safer assets so you’re not forced to withdraw from your portfolio in a falling market. Not every dollar should be invested at all times. That’s how you manage risk — not by locking yourself into a complex product that quietly limits your growth.

Investing directly in the S&P 500 through a Roth IRA, a 401(k), or a brokerage account is going to be the stronger long-term option than an IUL as an investment.

Yes, you’ll experience volatility. But I would rather accept a few temporary losses to capture long-term growth than give up a large portion of my returns every single year.

Because when you really look at the numbers, the so-called “safety” of an IUL often comes at a much higher cost than people realize.

And that’s why understanding the math — not just the marketing — matters so much
