What is an IUL and How Does It Work?

Indexed Universal Life, or IUL, is a flexible and often misunderstood type of permanent life insurance. What sets it apart is how the cash value grows. It can rise with a market index, while a built-in floor helps protect it from market losses in a down year.

This guide breaks down how an IUL works, in plain English.

What is an IUL?

An IUL is a permanent life insurance policy that pairs a death benefit with a cash value account. Unlike Whole Life, where cash value grows at a fixed, guaranteed rate, an IUL links your cash value growth to the performance of a stock market index, such as the S&P 500.

Two features make an IUL distinct, the floor and the cap:

• Floor (usually 0%). If the index falls, your cash value is not reduced by that market drop. You are credited 0% for the year rather than taking a market loss.
• Cap (often 8% to 12%). If the index rises sharply, your credited growth is limited to a maximum rate. You give up some of the upside in exchange for protection from the downside. These figures are illustrative and vary by carrier and contract.

How does the cash value work?

When you pay your premium, part of it covers the cost of insurance and policy fees. The rest goes into your cash value account. Each year, the insurer credits your account based on the index you chose, within the floor and the cap.

Over time the cash value can grow, and because of the floor, a market decline alone does not pull it down. Policy charges still apply, so a market drop is not the only thing that affects your balance, which is why proper funding matters. More on that below.

How is an IUL different from Whole Life?

Both are permanent policies that build cash value, but they work differently:

• Whole Life grows cash value at a fixed, guaranteed rate, often around 2% to 4%. Predictable and steady.
• IUL grows cash value based on index performance within a floor and a cap. More growth potential than Whole Life, but results vary from year to year.

An IUL also tends to offer more flexibility. You can adjust your premium and death benefit as your life changes. For a fuller comparison, read IUL vs. Whole Life.

Who is an IUL best for?

• People who want permanent coverage with more growth potential than Whole Life
• Higher earners who have maxed out their 401(k) and IRA and want another tax-advantaged place to save
• Business owners who want a flexible planning tool
• People who want index-linked growth with protection from market losses
• People in their 30s to 50s who have time to let the cash value build

What are the downsides of an IUL?

An IUL is useful, but it is not the right fit for everyone. A few things to weigh:

• Complexity. An IUL has more moving parts than Term or Whole Life, so working with a knowledgeable agent matters.
• Fees. There are internal costs, including the cost of insurance, administrative fees, and surrender charges in the early years.
• Caps. In an exceptional market year, you will not capture all of the gains.
• Funding. An underfunded policy can lapse over time, so it needs to be structured and funded correctly from the start.
