Grow your cash value linked to the performance of major market indexes like the S&P 500 — with a guaranteed 0% floor that protects you when markets decline. Upside potential, downside protection.
Indexed Universal Life (IUL) is a type of permanent life insurance where your cash value growth is linked to a stock market index — but you are never directly invested in the market. Instead, the insurance company credits your account based on the index performance, subject to a cap and a floor.
When the index goes up, you earn a return up to the cap rate (typically 8–14%). When the index goes down, your floor protects you — you earn 0%, meaning you never lose cash value due to market declines.
Your guaranteed minimum return. Even if the S&P 500 drops 30%, your cash value is credited 0% — not negative. You keep every dollar of prior gains.
The maximum return credited in any period. If the S&P 500 returns 25% and your cap is 10%, you earn 10%. Caps are set by the insurer and can change annually.
Cash value growth tied to the S&P 500, Nasdaq-100, or other indexes. You participate in market upside without owning any stocks.
The 0% floor means market crashes cannot reduce your cash value. Your gains are locked in at each annual reset point.
Cash value grows tax-deferred. Access via tax-free policy loans. Death benefit passes income tax-free to beneficiaries.
Most IUL policies use point-to-point crediting with an annual reset. Each year starts fresh — prior losses are irrelevant to your next credit.

Bull Market Scenario: The S&P 500 returns +22% this year. Because your cap is 10%, your cash value is credited +10%. The remaining 12% goes to the insurer to fund the floor guarantee. With $100,000 in cash value, you would gain $10,000, bringing your total to $110,000.

| Year | S&P 500 Return | 10% Cap / 0% Floor | 12% Cap / 0% Floor | No Cap / 75% Participation |
|---|---|---|---|---|
| Year 1 | +22% | +10.0% → $110,000 | +12.0% → $112,000 | +16.5% → $116,500 |
| Year 2 | -15% | +0.0% → $110,000 | +0.0% → $112,000 | +0.0% → $116,500 |
| Year 3 | +18% | +10.0% → $121,000 | +12.0% → $125,440 | +13.5% → $132,228 |
| Year 4 | +5% | +5.0% → $127,050 | +5.0% → $131,712 | +3.75% → $137,186 |
| Year 5 | -8% | +0.0% → $127,050 | +0.0% → $131,712 | +0.0% → $137,186 |
| 5-Year Result | +22% cumulative | +27.1% | +31.7% | +37.2% |

IUL works best for specific financial profiles and goals.
Seeking tax-advantaged growth beyond 401(k)/IRA limits with downside protection.
Already contributing maximum to retirement accounts and looking for additional tax-advantaged vehicles.
Using IUL for executive bonus plans, key person coverage, or tax-efficient business succession.
Patient investors with a 15+ year time horizon willing to trade some upside for downside protection.
IUL offers compelling benefits, but transparency builds trust. Here are the key considerations.
In strong bull markets, you miss out on returns above the cap. A 10% cap means you earn 10% even when the S&P returns 30%. Over time, this can significantly lag a direct index investment.
Monthly COI charges increase as you age. In later years, these charges can consume significant cash value, especially if the policy is underfunded or index returns are low for extended periods.
IUL policies typically have 10-15 year surrender charge periods. Surrendering early means losing a percentage of your cash value. This is a long-term commitment.
IUL is the most complex life insurance product. Cap and participation rates can change annually at the insurer's discretion, making long-term projections uncertain.
Answers to the most common questions about indexed universal life.
IUL is not a traditional investment but a life insurance product with investment-like features. It offers tax-deferred growth linked to market indexes with downside protection. It works best as a supplement to maxed-out retirement accounts, not as a replacement for diversified investing.
Most IUL policies offer the S&P 500 as the primary index option. Many also offer the Nasdaq-100, Russell 2000, Euro Stoxx 50, or custom hybrid indexes. You can typically allocate cash value across multiple indexes and a fixed-rate account.
Your cash value cannot decrease due to index performance thanks to the 0% floor. However, monthly cost of insurance charges and fees are deducted regardless. In years where the index returns 0%, these charges reduce your cash value. Persistent poor markets combined with charges can erode value over time.
Both offer tax-free income in retirement. Roth IRAs have lower fees and more flexibility but annual contribution limits ($7,000 in 2024). IUL has no contribution limits, includes a death benefit, and offers downside protection, but has higher costs and caps. Many high-income earners use both together.
The cap rate is the maximum return credited in a given period. With a 10% cap, if the S&P 500 returns 25%, you earn 10%. Caps typically range from 8-14% and can change annually at the insurer's discretion based on the options market.
The participation rate determines what percentage of index return is credited. With 75% participation and no cap, a 20% index return credits 15% to your cash value. Some policies use participation rates instead of or in addition to caps.
IUL policies typically have 10-15 year surrender charge periods with declining percentages. After the period ends, you can access full cash value without penalty. Policy loans offer an alternative way to access funds during the surrender period.
