Turning 40 can change the way you think about money.

Retirement may still feel far away, but suddenly it isn't that far away. You may be earning more than you did in your 20s, raising a family, paying a mortgage, building a career, or simply thinking more seriously about what you want your finances to look like over the next 20 to 30 years.

This can also be a good time to take a closer look at your life insurance.

One option you may hear about is Indexed Universal Life Insurance, commonly called IUL.

An IUL isn't simply an investment account. It's a form of permanent life insurance designed primarily to provide a death benefit, while also offering the potential to accumulate cash value over time.

What Is Indexed Universal Life Insurance?

Indexed Universal Life is a type of permanent life insurance that can remain in force for your lifetime as long as the policy requirements are met.

Part of the premiums you pay goes toward the cost of insurance and other policy expenses, while the policy may also build cash value.

The interest credited to that cash value can be linked to the performance of a market index, such as the S&P 500.

Here's an important distinction:

Your money is not directly invested in the stock market or the index.

Instead, the insurance company uses a formula to determine how much interest is credited based partly on the performance of the selected index. Caps, participation rates, spreads, floors and other policy provisions can affect how much interest is actually credited.

Why Your 40s Can Be an Important Time

Imagine you're 40 years old today.

The Social Security full retirement age for someone born in 1960 or later is currently 67.

That gives you approximately 27 years before reaching age 67.

That's potentially 27 years for a properly funded IUL policy to accumulate cash value.

A Simple Illustration

Think about the timeline like this:

AGE 40
🌱 Policy begins
You establish your coverage and begin funding the policy.

↓

AGE 45
🌿 Cash value has had five years to potentially accumulate.

↓

AGE 50
🌳 You've now had approximately 10 years of potential cash-value accumulation.

↓

AGE 60
🌳🌳 You've had approximately 20 years.

↓

AGE 67
🏁 You reach today's Social Security full retirement age with approximately 27 years of policy history.

This does not mean your cash value is guaranteed to increase every year or reach a particular dollar amount.

The actual results depend on your specific policy, premiums, insurance costs, credited interest, policy expenses, withdrawals or loans, and many other factors.

That's why an official insurance-company illustration is so important when considering an IUL.

What Could Cash-Value Growth Look Like?

Instead of saying, “If you put in $X, you'll have $500,000 at retirement,” it's better to look at an individualized illustration.

For example, two 40-year-olds could purchase IUL policies at the same time and experience very different results.

One person might contribute substantially more premium. Another may choose a larger death benefit. Their health classifications could be different. One might take policy loans later in life while the other doesn't.

All of these factors can affect the policy.

When I show a client an IUL, I can provide an illustration based on that person's age, coverage amount, premium, underwriting assumptions and policy design so they can see both guaranteed and non-guaranteed values.

What Makes an IUL Different?

There are three major features to understand.

1. Life Insurance Protection

First and foremost, an IUL is life insurance. It provides a death benefit to your beneficiaries as long as the policy remains in force.

2. Cash-Value Potential

The policy can accumulate cash value over time. Interest credited to the policy may be linked to the performance of a market index, subject to the policy's terms.

3. Flexibility

Universal life insurance generally provides flexibility regarding premiums and death benefits within certain policy limits. However, paying too little or taking too much from the policy can negatively affect its performance or even cause it to lapse.

Can You Use IUL Cash Value During Retirement?

Potentially, yes.

Policyowners may be able to access available cash value through withdrawals or policy loans.

This is one reason some people consider permanent life insurance as part of a broader long-term financial strategy.

But there's an important catch.

Policy loans and withdrawals reduce available cash value and death benefits and can increase the possibility of the policy lapsing. A lapse with an outstanding loan may also create tax consequences.

An IUL therefore shouldn't be presented as simply a “tax-free retirement account.”

It's life insurance, and it needs to be properly designed, funded and monitored.

Starting at 40 vs. Waiting Until 50

Time can make a major difference with permanent life insurance.

Starting earlier can potentially give cash value more time to accumulate and may also allow you to apply for coverage when you're younger.

Waiting another 10 years means you're applying at an older age, which can affect insurance costs and gives the policy less time before retirement.

That doesn't mean everyone in their 40s should purchase an IUL.

It means your 40s can be a smart time to evaluate your life insurance and long-term financial strategy instead of waiting until retirement is right around the corner.

Is an IUL Right for You?

An IUL can make sense for certain people, but it isn't the right product for everyone.

Before purchasing one, you should understand:

  • How much life insurance you actually need
  • How much premium you can comfortably afford
  • Policy fees and insurance costs
  • How indexed interest is calculated
  • Caps, floors and participation rates
  • Guaranteed versus non-guaranteed values
  • How loans and withdrawals work
  • What could cause the policy to lapse

The goal shouldn't be to buy an IUL simply because someone showed you an impressive future number.

The goal should be to understand how the policy works and whether it fits your needs.

Your 40s Aren't Too Late to Start Planning

If you're approaching 40—or you're already in your 40s—you may still have decades before retirement.

Those years matter.

An Indexed Universal Life policy can provide permanent life insurance protection while offering the potential to accumulate cash value over time. But like any long-term financial product, it should be designed around your individual circumstances.

If you're curious about what an IUL could look like for you, I can walk you through an individualized policy illustration so you can see the numbers, assumptions, costs and potential cash values for yourself.
