What Is IUL Insurance—and Can You Lose Money?

By Steven Lapa | Licensed Insurance Broker · October 5, 2026

Indexed universal life insurance, or IUL, is permanent life insurance with cash value that may earn interest linked to an index. It does not directly invest your cash value in that index. A 0% index-crediting floor does not mean your total policy value can never decrease.

How index-linked interest works

An indexed account uses a contract formula to determine interest credits. Features such as a cap, participation rate, or spread can limit the credit. The specific formula, guarantees, and renewal terms matter more than the index name alone.

A positive stock-market year does not mean the policy receives the same return as the market.

What the floor protects—and what it does not

Where a policy provides a 0% floor, a negative index result does not create a negative index-interest credit for that segment. However, insurance costs and policy charges still apply. Loans and withdrawals can also affect values, and surrender charges may reduce what is available if you exit early.

That is why "you cannot lose money" is an incomplete description of IUL.

What about using cash value later?

Policy loans may offer access to available value, but interest accrues and unpaid loans reduce the benefit left to beneficiaries. A lapse or surrender with outstanding loans can create taxable income. Modified endowment contracts have different tax treatment.

"Tax-free retirement" should never be treated as an unconditional promise. Review the policy design, funding, loan assumptions, and tax implications before using insurance as part of a retirement strategy.

Questions worth asking before you apply

  • Why does permanent life insurance fit my needs?
  • What happens if interest credits are lower than illustrated?
  • Can I afford the funding plan through difficult years?
  • What charges apply, and which terms can change?
  • How will we review the policy as it ages?

Ask for guaranteed and nonguaranteed results to be explained separately. Consider lower-crediting scenarios instead of relying only on the illustrated projection.

Frequently asked questions

Is IUL the same as investing in the S&P 500?

No. It is an insurance contract with its own crediting method and costs.

Can I stop paying whenever I want?

Flexible premiums do not eliminate policy expenses. Inadequate funding can lead to lapse unless applicable guarantees and their conditions protect the coverage.
