Indexed Universal Life (IUL)
Indexed universal life (IUL) is permanent life insurance with flexible premiums and cash value that earns interest linked to the performance of a market index. It is a more complex product, and how it performs depends heavily on funding, policy charges, and the crediting terms.
Who it may suit
- People who want permanent coverage with premium flexibility
- Those interested in index-linked cash-value growth potential
- Buyers comfortable with a more complex, illustration-based product
How it generally works
You pay flexible premiums into the policy. The cash value earns interest based on the change in a market index, subject to a cap and a participation rate, with a floor (often 0%) that limits index-based losses.
You are not directly invested in the market index. Policy charges and the cost of insurance are deducted from the policy, which can reduce cash value — a 0% floor does not mean the policy cannot lose value.
Illustrations use assumptions that are not guarantees. If a policy is underfunded or charges rise, it can underperform or even lapse. Loans and withdrawals can affect benefits and performance.
Potential advantages
- Flexible premiums within policy limits
- Index-linked growth potential with a downside floor on crediting
- Permanent coverage with tax-advantaged cash value access
Important limitations
- Caps and participation rates limit index-linked crediting
- Policy charges can reduce cash value even in a flat index year
- Complex; adequate, sustained funding is important to performance

How it compares
Indexed Universal Life (IUL): frequently asked questions
Can an IUL lose value?
Index-linked crediting typically has a floor, but policy charges and the cost of insurance are still deducted, so cash value can decline — especially if the policy is underfunded. A 0% floor does not mean no loss of value.
Is an IUL a retirement plan?
No. IUL is life insurance and should not be presented as a guaranteed retirement strategy. Any cash-value use has tradeoffs we will explain, and you should consult a tax professional.
Are the illustration numbers guaranteed?
No. Non-guaranteed illustrations rely on assumptions that may not occur. We will also review the guaranteed columns with you.
