Summary

An IUL policy loan lets you borrow against your policy's cash surrender value while the cover stays in force. The choice between a fixed loan and a participating loan turns on one number: the spread between what you are charged and what the borrowed value is credited.

  • A fixed loan moves the borrowed value into a separate loan account at a declared crediting rate. Charged 5.75% against a 4.50% credit, the net cost on $100,000 is $1,250 and it is known in advance.
  • A participating loan leaves the borrowed value in the index strategy. Charged 4.75% against a 6.00% index credit, the same $100,000 produces a $1,250 gain — but only if the index delivers.
  • In a zero-credit year the fixed loan still costs $1,250. The participating loan costs the full $4,750, because the interest is payable whether or not a credit is applied.
  • Most insurers lend up to 80–90% of cash surrender value, and any outstanding loan plus accrued interest comes off the death benefit, $2,900,000 on a $3,000,000 policy.

Introduction

Accessing liquidity shouldn’t always mean selling assets or approaching the bank.

For high-net-worth clients, Indexed Universal Life (IUL) insurance provides a more private option — the ability to borrow against policy cash value while keeping protection intact and growth potential alive.

An IUL loan works like a personal credit facility built inside the policy. Whether used for opportunity funding, estate liquidity, or retirement planning, it’s a useful feature when managed correctly.

This article breaks down the difference between Fixed and Participating (Indexed) loans, shows how to calculate each, and highlights the core points advisers must consider before using them in client plans.

What Is an IUL Policy Loan?

An IUL loan lets you access part of your policy’s cash surrender value while keeping your life insurance in force. The insurer advances the loan and charges interest; your policy acts as collateral.

Depending on the loan type, the borrowed value may continue earning index credits or switch to a separate loan account. When the insured passes away, any loan and interest are deducted from the death benefit before payout.

IUL Fixed Loans

How Fixed Loans Work

  • The insurer transfers the borrowed cash into a loan account.
  • You pay a loan interest rate declared by the insurer.
  • The borrowed funds earn a loan crediting rate, usually lower than the normal index strategy.
  • The spread between these rates is your net cost.

Fixed Loan Example

Item Amount Calculation
Net Cash Surrender Value $1,000,000 Input
Death Benefit $3,000,000 IUL Illustration
Loan Amount $100,000 IUL Illustration
Loan Account Interest Rate 5.75% —
Loan Crediting Rate 4.50% —

‍

Year 1 Interest Calculations

  • Interest Payable: $100,000 × 5.75% = $5,750
  • Interest Credited: $100,000 × 4.50% = $4,500
  • Net Loan Cost: $5,750 − $4,500 = $1,250

Impact on Death Benefit

If the insured dies with a $100,000 loan:

$3,000,000 − $100,000 = $2,900,000 to beneficiaries.

Summary: Predictable borrowing cost of 1.25% and continued life cover.

IUL Participating / Indexed Loans

How Participating Loans Work

  • The borrowed value stays in the index strategy.
  • You still pay loan interest, but there’s no separate account.
  • The outcome depends on the spread between the loan rate and the index credit.
    • If index credit > loan charge → positive arbitrage.
    • If index credit < loan charge → net cost.

Indexed Loan Example

Item Amount Calculation
Net Cash Surrender Value $1,000,000 Input
Death Benefit $3,000,000 IUL Illustration
Loan Amount $100,000 Input
Loan Interest Rate 4.75% —
Index Crediting Rate 6.00% —

‍

Year 1 Interest Calculations

  • Interest Payable: $100,000 × 4.75% = $4,750
  • Interest Credited: $100,000 × 6% = $6,000
  • Net Result: $4,750 − $6,000 = –$1,250 (Gain)
Summary: Positive arbitrage — the policy effectively earns $1,250 more than it pays.

Collateral & Loan-to-Value (LTV)

  • Cash surrender value acts as collateral.
  • Most insurers allow borrowing up to 80–90% of CSV.
  • If loans and interest approach the total value, additional premium or repayment is required to prevent lapse.

Key Factors Driving Loan Outcomes

FactorFixed loanParticipating (indexed) loan
Where the borrowed value sits Moved out of the index strategy into a separate loan account. Stays in the index strategy and continues to be credited.
Interest charged Declared by the insurer — 5.75% in the example above. Declared by the insurer — 4.75% in the example above.
Credit on the borrowed amount A loan crediting rate, usually below the index strategy — 4.50%. The index credit, subject to the cap, participation rate and floor — 6.00%.
The spread Known at the start of the year, because both sides are declared. Not known until the crediting date, because only the charge is declared.
Net result in the example 1.25% cost — $1,250 on $100,000. 1.25% gain — $1,250 on $100,000.
A zero-credit year Unchanged. The loan crediting rate still applies, so the cost stays at $1,250. The floor prevents a negative credit, but the interest is still payable — the full $4,750 becomes a cost.
Loan-to-value Up to 80–90% of cash surrender value. Moves with the loan balance. Up to 80–90% of cash surrender value. Moves with the balance and with index performance.
Interest compounding Accrues whether or not it is paid, and compounds against the policy. Accrues whether or not it is paid, and compounds against the policy.
Effect on the death benefit Loan and accrued interest deducted before payout — $2,900,000 on the $3,000,000 policy. Loan and accrued interest deducted before payout, on the same basis.
Lapse risk Rises steadily, because the spread is a cost in every year. Rises faster after consecutive weak index years, when the charge is unmatched by a credit.

Top 5 Adviser Considerations

  1. Confirm loan type (fixed or participating).
  2. Check loan rate mechanics and whether variable or capped.
  3. Understand spread provisions (“wash” or “preferred” loans).
  4. Review how the loaned amount is credited.
  5. Confirm interest compounding frequency and repayment options.

Summary Table: Fixed vs Participating Loans

Fixed loanParticipating (indexed) loan
Interest charged 5.75% 4.75%
Credited on the borrowed amount 4.50% loan crediting rate 6.00% index credit
Net result on $100,000 $1,250 cost $1,250 gain
In a zero-credit year $1,250 cost — unchanged $4,750 cost
Certainty Both sides of the spread are declared, so the cost is known in advance. Only the charge is known in advance. The credit is not.
Suits Clients who want a borrowing cost they can budget for, and loans held across uncertain markets. Clients who can carry a variable cost, over horizons long enough for index years to average out.
Main risk The spread is a cost in every year, including strong ones. Consecutive weak index years turn the arbitrage into a compounding cost against the policy.

Conclusion

Both loan types can serve clients well when used with discipline. Fixed loans suit those wanting predictability, while participating loans reward index-linked growth.

For advisers, success lies in managing loan spreads, LTV ratios, and policy health to preserve both liquidity and protection.
