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 powerful 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.
