Indexed Universal Life Insurance: How It Works and What to Know
Indexed universal life insurance (IUL) is a type of permanent, cash-value life insurance. Like universal life insurance, an IUL policy lets you adjust your coverage level, premium amounts, and payment frequency — but with a key difference: cash value growth is tied to the performance of a market index.
This guide explains how indexed universal life insurance works, its key features, and what to consider before purchasing an IUL policy.
Background: How IUL Combines Whole Life and Universal Life Features
Indexed universal life insurance was developed to combine features from two other types of permanent life insurance:
- Whole life insurance offers permanent death benefits with fixed premiums and a guaranteed minimum interest rate, but it lacks flexibility.
- Universal life insurance adds flexible premium timing and amounts, along with the ability to adjust the death benefit (increasing the death benefit may require additional underwriting). However, the interest credited to cash value is controlled by the policy issuer.
IUL combines the guarantees* of whole life insurance with the flexibility of universal life insurance, while offering the opportunity for cash value growth tied to the performance of an equity index — without direct exposure to losses from unfavorable index performance.
*Guarantees are subject to the financial strength and claims-paying ability of the insurance issuer.
How Indexed Universal Life Insurance Works
An IUL policy credits excess interest to your cash value based on the performance of a selected market index, rather than a fixed interest rate. If the index performs well, the policy earns interest. If the index performs poorly, most IUL policies still credit a minimum interest rate, protecting the cash value from index losses.
Several factors determine how much interest an indexed universal life insurance policy actually earns.
The Equity Index
IUL policies are tied to a selected market index, such as:
- Dow Jones Industrial Average
- S&P 500 Index
- Various bond indexes
The interest credited to the policy depends on the gain in the selected index over a specific index term.
Index Term
The index term is the period over which index performance is measured. Some index terms last one year, while others last two years or longer. At the end of the term, the insurer calculates the interest to be credited to the policy.
Participation Rate
The participation rate determines how much of the index’s gain is credited to your IUL policy.
Example:
- Index gain: 20%
- Participation rate: 90%
- Credited interest: 18% (20% × 0.90)
Some insurers offer participation rates of 100% or more, while a lower participation rate reduces the credited interest.
The Interest Rate Cap
Many insurers also apply an interest rate cap, which sets the maximum interest that can be credited to the cash value during the index term, regardless of the participation rate.
Example: Using the scenario above, if a 12% cap applies in addition to the 90% participation rate, the policy is credited 12% interest — not 18% — because the cap sets the ceiling.
Key Features of Indexed Universal Life Insurance
An IUL policy offers:
- Permanent coverage with flexible premiums and adjustable death benefits
- Cash value growth credited based on equity index gains
- A minimum guaranteed interest rate on some policies, even during poor index performance
- Coverage that remains active as long as premiums are paid
- An optional lifetime death benefit feature, which keeps coverage in place for life but may increase premiums
Accessing Your IUL Cash Value
Cash value in an indexed universal life insurance policy grows tax-deferred, meaning no income tax is owed on credited interest while it remains in the policy.
You can access IUL cash value in two ways:
- Withdrawals — up to your premium basis, generally tax-free
- Policy loans — borrowed against the policy’s cash value
Important: Withdrawals and loans reduce both the cash value and the death benefit, and surrender charges may apply.
Tax Advantages and Considerations
- Withdrawals from accumulated cash value, up to the amount of premiums paid, are not subject to income tax.
- Policy loans are generally tax-free, provided they are repaid.
- Loans and withdrawals reduce both the policy’s cash value and death benefit.
Risks and Fees to Understand
Before purchasing an indexed universal life insurance policy, it’s important to understand the associated risks and costs:
- If the policy lapses or is surrendered with an outstanding loan balance, that balance may be treated as a taxable distribution.
- IUL policies typically include mortality and expense charges.
- Cancelling or surrendering a policy may result in surrender charges and potential tax consequences.
- During periods of negative index performance, cash value may earn little or no interest.
- Reducing or skipping premium payments may require higher payments later to maintain coverage or prevent the policy from lapsing.
Other Factors to Consider Before Buying IUL
Indexed universal life insurance has more moving parts than many other universal life policies. Before purchasing, consider:
- Participation rates
- Interest rate caps
- Interest crediting methods
- Surrender charges
- Annual insurance cost increases

An IUL policy may be worth considering if you:
- Want permanent life insurance coverage
- Prefer flexible premium payments
- Plan to hold the policy for 10 or more years
- Want growth potential without direct market risk

Frequently Asked Questions
What is indexed universal life insurance?
Indexed universal life insurance is a type of permanent life insurance that combines flexible premiums and adjustable death benefits with cash value growth tied to the performance of a selected market index.
How does indexed universal life insurance work?
An IUL policy credits interest to your cash value based on the gains of a selected index, such as the S&P 500, subject to a participation rate and often an interest rate cap. Most policies also guarantee a minimum interest rate during poor index performance.
What is a participation rate in an IUL policy?
The participation rate determines what percentage of an index’s gain is credited to your policy’s cash value. For example, a 90% participation rate on a 20% index gain credits 18% interest.
What is an interest rate cap in indexed universal life insurance?
An interest rate cap sets the maximum interest that can be credited to your cash value during an index term, even if the index gain and participation rate would otherwise produce a higher return.
Can I lose money in an IUL policy if the index performs poorly?
Most IUL policies protect cash value from direct index losses by crediting a minimum guaranteed interest rate, even when the index performs poorly.
How can I access the cash value in my IUL policy?
You can access IUL cash value through withdrawals up to your premium basis (generally tax-free) or through policy loans. Both options reduce the cash value and death benefit.
Are indexed universal life insurance withdrawals taxable?
Withdrawals up to the amount of premiums paid are generally not subject to income tax. Amounts beyond that, or loans not repaid before the policy lapses or is surrendered, may be taxable.
