How does IUL insurance work?

With indexed universal life (IUL) insurance, you can get a policy that may grow and adapt with your needs. Part of your premium covers the cost of insurance, while the rest goes into a cash value account that earns interest based on the performance of a market index.


Here are some key components of IUL insurance.


1. Premium payments

You can adjust your premiums up or down as needed, depending on your financial situation. Each payment covers insurance costs and policy fees, while the remaining amount goes toward your policy’s cash value.


2. Cash value growth

Your cash value grows tax-deferred and can earn interest based on the performance of the chosen index. If the market rises, your policy earns interest up to a certain cap. If the market drops, a floor may limit the impact of negative index performance; however, policy charges and fees can still affect cash value.


3. Access to cash value 

Over time, you can, subject to policy terms and conditions, tap into your policy's cash value through loans or withdrawals, using it to supplement retirement income, pay for college, or handle emergencies. 


You can repay loans over time, and any unpaid amount reduces your death benefit. Some policyholders use this feature as part of an infinite banking strategy to become their own source of financing. They use policy loans as a personal financing tool, though loans accrue interest and may reduce policy values and death benefits if unpaid.


4. Death benefit 

The death benefit ensures that your loved ones receive a payout upon your passing. This benefit can support your family’s financial future, cover final expenses, or even fund wealth transfer strategies.

What’s an example of indexed universal life insurance?

Imagine you purchase an IUL policy with a $500,000 death benefit and contribute $500 per month. A portion of each payment covers insurance and fees, while the rest earns interest linked to an index. 


If the index rises 8%, and your policy’s cap is 10%, your cash value could earn near the maximum credit. If the market falls, your 0% floor may help ensure your cash value remains stable, subject to caps, charges, and policy costs.

Keep in mind, IUL policies need to be set up correctly to work as intended; that’s why working with experts matters. The fee schedules can be complex, and you may need to tweak your payments to avoid underfunding the policy when the market is down.

Pros and cons of an IUL policy

IUL policies offer appeal by combining growth potential with protection. They offer flexible premiums, tax-deferred cash value growth, and a floor that limits the impact of negative index performance, subject to caps, charges, and policy costs, while allowing for gains up to a cap. 


However, they’re more complex than traditional term life insurance, with fees and interest caps that can limit returns, and they require regular monitoring to remain in force.

IUL vs. term life vs. whole life insurance

Each type of life insurance serves different financial goals. The main difference lies in how each policy builds cash value and handles premiums. 


Term life is the most straightforward, having no cash value component. Whole life offers slow, steady cash value growth with fixed premiums.


IUL insurance sits between these options, offering lifelong coverage with market-linked growth potential and flexible premium payment options.

Is an IUL policy right for you?

An IUL life insurance policy may be ideal if you want both protection and the opportunity to build tax-advantaged wealth. It especially suits:

  • Families looking for lifelong coverage with growth potential
  • Business owners seeking flexible liquidity
  • Individuals wanting tax-efficient retirement income*
  • Parents saving for education or future expenses
  • Those concerned about market volatility but still wanting growth

*Note, however, that IUL policies are not retirement plans or investment accounts, so you should really think of them primarily as life insurance that has other potential benefits.


If you’re unsure whether an IUL fits your goals, Amplify’s licensed insurance experts can help you explore if it aligns with your personal strategy.


Life insurance for everything in life

IUL life insurance offers more than protection for your loved ones. It serves as a tool for building generational wealth. It can help you grow assets steadily, maintain access to funds, and ensure your family stays financially protected no matter what happens.

Frequently Asked Questions

Note

Important: Indexed universal life insurance (IUL) is a form of permanent life insurance and is not an investment or a retirement plan. While an IUL policy may credit interest based on the performance of a market index, it does not directly invest in the market, and index performance does not include dividends. Interest crediting is subject to caps, participation rates, and other policy limits, which may change. Although many policies include a floor that can limit the impact of negative index performance, cash value is not guaranteed and may be reduced by policy charges, cost of insurance, rider fees, loan interest, or insufficient premiums. Accessing cash value through loans or withdrawals will reduce cash value and death benefits and may cause the policy to lapse, potentially resulting in taxable consequences. Tax treatment is based on current law and may change. Hypothetical examples are for illustrative purposes only and do not reflect actual policy performance. Consumers should consult their own tax, legal, and financial professionals regarding their individual circumstances.
