How to Choose the Best Index Universal Life Insurance Policy
In an increasingly complex financial world, life insurance policies are evolving beyond simple death benefits. For those seeking both lifelong protection and investment potential, Index Universal Life (IUL) insurance stands out. But with dozens of carriers offering variations on this product, how do you choose the best IUL policy for your needs in 2025?
This article breaks down what makes an IUL policy “the best” — and how to evaluate features, performance metrics, and provider credibility to ensure you’re making a long-term, smart decision.
What Does “Best” Mean in IUL Insurance?
Unlike term life insurance, where price is often the only differentiator, the best IUL policy depends on your personal goals. Some policies excel in cash accumulation. Others prioritize low-cost death benefit coverage. The “best” IUL policy is the one that aligns most closely with your needs in areas such as:
- Tax-free retirement income
- Legacy planning and estate preservation
- Liquidity access via policy loans
- Living benefits like long-term care riders
1. Best Index Credit Strategies
The most competitive IULs in 2025 offer multiple index options for cash value growth. These policies allow you to diversify and adapt based on market performance. Key features of top-tier index strategies include:
- Multiple Indices: Look for access to the S&P 500, NASDAQ-100, EURO STOXX 50, and proprietary volatility-controlled indexes.
- High Participation Rates: The best policies offer 100% or more participation in market gains (subject to caps).
- Attractive Cap Rates: Cap rates above 10% are strong in today’s rate environment.
- 0% Floor Protection: Ensures your cash value doesn’t decline in a bear market.
2. Best IUL Policies for Retirement Income
If your goal is long-term income, the best IUL will offer strong cash value accumulation with low internal policy charges. You’ll also want flexible loan options:
- Participating Loans: Let your cash value continue to earn interest even when borrowed against.
- Zero Net Cost Loans: Some insurers offer policy loans with net-zero interest after year 10 or 15.
- Automated Income Withdrawals: Some policies support scheduled loans or withdrawals, simplifying retirement income planning.
3. Best for Living Benefits and Health Riders
Modern IULs can include valuable living benefit riders that turn your policy into a multi-purpose safety net. The best options in 2025 include:
- Accelerated Death Benefit Riders: Access funds early in the event of chronic, critical, or terminal illness.
- Long-Term Care (LTC) Riders: Some IULs allow partial death benefit withdrawals for qualified LTC expenses — without a separate LTC policy.
- Disability Waivers: Premiums may be waived if the policyholder becomes disabled.
4. Best IULs for Flexibility and Customization
Premium flexibility and policy customization are key features that separate the best IULs from the rest:
- Adjustable Death Benefits: Choose level or increasing options; adjust as your needs change.
- Flexible Premiums: Overfund the policy in good years or reduce premiums during tight periods — as long as policy remains in force.
- Allocation Control: Shift funds annually between fixed accounts and indexed accounts to optimize returns.
5. Best Insurance Carriers in 2025 Offering IUL
While product design matters, the strength of the insurer is just as critical. The best IUL policies come from highly rated, reputable companies with strong financials and responsive client support.
- Financial Ratings: Look for insurers with A or better ratings from A.M. Best, S&P, and Moody’s.
- Digital Capabilities: The best carriers offer digital dashboards, online loan requests, and easy-to-read statements.
- Historical Performance: Ask for a carrier’s past index crediting history and cost of insurance trends to see how their policies have performed in real-world conditions.
6. Best IUL for Estate Planning
Some policies are structured specifically for wealth transfer and estate preservation. If legacy planning is a priority, the best IUL for you may include:
- Guaranteed Death Benefit Options: Ensures your heirs receive the full benefit regardless of market performance.
- No-Lapse Guarantees: Protects the death benefit even if cash value declines, provided premiums are paid as required.
- Trust-Friendly Design: Easily owned or managed through irrevocable life insurance trusts (ILITs).
