IUL vs 401(k): Which Should You Fund First?

If you have a 401(k) at work and somebody just told you an IUL is better, this one is for you. The IUL vs 401k question comes up in my conversations constantly, and the internet is not helping. One side says an IUL is a scam. The other side says your 401(k) is a trap. Both of those are too simple.

Just to be completely clear before we start: I own an IUL, I put money in it every month, and I still think most people should not touch their 401(k) match to fund one. An IUL is an amazing piece of a full plan. It is not the whole plan. So let me give you just a couple things about how these two actually compare, and where each one belongs.

What is the difference between an IUL and a 401(k)?

A 401(k) is an employer retirement account you fund through payroll, while an indexed universal life policy is permanent life insurance with cash value that earns interest linked to a market index. One is a retirement account. The other is life insurance you can also build cash inside of. If you want the mechanics of the policy side, start with how indexed universal life policies work.

Sources for the numbers: the IRS set the 2026 limits in Notice 2025-67, and the early withdrawal rules are in IRS Topic 558. The IUL funding limits come from tax code sections 7702 and 7702A, and the death benefit treatment from section 101.

IUL vs 401k: is one actually better?

Neither one is better across the board, because they do different jobs. Asking whether an IUL or a 401k wins is like asking whether your car or your house is the better purchase. You probably need somewhere to live and a way to get to work.

I like to say a good plan is the burger, the shake, and the fries, and most people walk around with just the fries. In money terms you want three buckets. Fixed money like savings and CDs. Variable money like the funds in your 401(k), where you take market risk for market growth. And indexed money, which is where an IUL lives, with growth tied to an index and a floor under the credits. When people fight about IUL vs 401k, they are arguing about which single bucket to keep. I would rather you have more than one.

Should I stop my 401(k) match to fund an IUL?

No. If your employer offers a match, I would take the full match before putting a dollar into an IUL. That is my honest opinion, and I will say it to anybody.

Here is a hypothetical. You make $60,000 and your company matches dollar for dollar up to 4%. You put in $2,400 a year and they add $2,400. That is a 100% gain on your money before the market even moves, assuming you stay long enough to vest. No index strategy with a cap is going to compete with that.

So if anybody tells you to turn off your match to fund a policy, ask them to show you the math in writing, and then get a second opinion. That's the thing. A good policy should never need you to walk away from free money.

Can an IUL replace a 401(k)?

For most W-2 employees, an IUL should sit next to a 401(k), not replace it. A 401(k) gives you the match, a possible tax deduction today, lower costs, and uncapped growth. Those are real, and I am not going to pretend otherwise.

Where an IUL can do more of the heavy lifting is when the 401(k) is already handled or does not exist. Think of a business owner with no plan, or a high earner who already maxes out and wants another place to build. Even then it is a long game. Cash value is thin in the early years because charges are heaviest then, so I want to see you committed for 10 years or more. I wrote more on that in Is an IUL Good for Retirement?

What can an IUL do that a 401(k) can't?

An IUL can protect your family from day one while it builds, which a 401(k) simply is not designed to do. Here is what I would love for you to see on the IUL side:

• A death benefit. If you pass in year three, a 401(k) leaves three years of savings. An IUL leaves the full benefit, assuming the policy is in force.
• Living benefits. Many policies offer riders that can pay part of the benefit early for a terminal, chronic, or critical illness. Rules and costs vary by carrier.
• A floor in bad years. When the index drops, credits stop at the floor instead of going negative. Your policy charges still come out, so this does not mean your value can never fall. I talk more about staying steady in weathering financial storms.
• Access before retirement age. There is no 59 and a half rule on policy loans. Loans do charge interest and reduce your cash value and death benefit, so read these IUL loan strategies first.
• No required withdrawals. Traditional 401(k) money generally has required minimum distributions starting at 73. A life insurance policy does not.

I was at lunch with a friend in real estate not long ago, talking about what happens at 65 when you are tired of managing properties and you sell. Where does that money go? A properly funded policy can be one good answer, because it gives you a simpler place to live from. Not the only answer. One good one.

Where does an IUL fit in a full financial plan?

An IUL fits after the basics are handled, alongside your retirement accounts and not in front of them. Here is the order I usually walk people through:

1. Build a starter emergency fund.
2. Get your full 401(k) match.
3. Pay off high interest debt.
4. Get the right amount of life insurance protection. Sometimes that is term, and I will tell you so.
5. Finish your emergency fund, usually three to six months of expenses.
6. With what is left, decide among an IUL, a Roth IRA ($7,500 limit in 2026, with income limits), and more in your 401(k).

Step six is where the real conversation happens, and it depends on your age, income, health, and goals. There is no magic wand. I don't own any.

Who is an IUL NOT for?

An IUL is not for anyone who needs that money somewhere else first, and that covers more people than my industry likes to admit. I would tell you to wait or skip it if:

• You are not getting your full 401(k) match yet.
• You have credit card debt or no emergency fund.
• You can't see yourself funding it consistently for 10 years or more. Stopping early is where these go wrong.
• You only need coverage for a set stretch, like while the kids are home. Term is usually the better tool.
• You want every bit of market upside and can sleep through the drops.
• Your age or health would make the insurance costs too heavy. See what underwriting really looks at.

Can I move my 401(k) into an IUL?

You can't roll a 401(k) directly into an IUL the way you roll it into an IRA. Taking money out of a traditional 401(k) to pay premiums is a taxable distribution, and if you are under 59 and a half you may owe a 10% penalty too. Anybody who makes that sound simple is leaving something out.

If someone is pitching you on moving money, ask these four questions before you do anything:

1. What are the total charges in the first 10 years, in dollars?
2. What happens to the illustration at a lower rate than the one you are showing me?
3. How long do the surrender charges last?
4. Is this built to stay under the MEC limit?

The first answer matters most, so here are the IUL fees to look for, and here is what a well structured IUL looks like. Does that make sense?
