Most IUL conversations focus on crediting strategies and accumulation. But the distribution phase is where a policy delivers on its promise — or disappoints. Understanding how each loan option works is essential before you illustrate retirement income for a client.
Key takeaways
- Most IUL policies offer a fixed loan option and a variable (indexed or “preferred”) loan option, and they behave very differently over time.
- Indexed loans can illustrate attractively through positive arbitrage, but negative arbitrage can erode the income a client was counting on.
- Check each product guide for the fixed loan rate, whether it’s participating, and what the variable loan rate is tied to or capped at.
If loan interest charged exceeds the interest credited to cash value, the amount available for distribution can fall well below the income your client expected.
Why distributions deserve as much attention as accumulation
With many carriers offering their own version of Indexed UL, keeping track of every product’s moving parts is close to a full-time job. Advisors often spend hours helping clients understand crediting and accumulation, then give the distribution phase much less attention.
Yet if the goal is supplemental retirement income, how the client takes money out matters just as much as how the policy grows. The loan provisions you choose — and how you explain them — shape the client’s experience for decades.
Fixed loans and wash loans
A fixed loan charges a stated interest rate, set in the contract, on the outstanding loan balance. There is no question about the cost of borrowing, which makes it the more predictable choice.
After a number of years (often around year 15), many IUL products provide a wash loan or zero-cost loan, where the rate charged on the loan equals the rate credited to the borrowed cash value. Confirm the timing and terms with each carrier, since they vary.
Indexed (variable) loans and the arbitrage question
The option most commonly illustrated is the indexed loan, sometimes called a preferred or participating loan. Borrowed cash value stays in the index strategy while loan interest accrues at a variable rate.
When the illustrated crediting rate exceeds the loan rate, the illustration shows positive arbitrage — a gain on the loan rather than a cost — which can make projected income look larger. That is why many producers prefer to show it.
The flip side is negative arbitrage. In years when crediting falls short of the loan rate, interest compounds against the policy, the available income can shrink, and in severe cases the policy can come under lapse pressure.
Matching the loan option to the client
Either loan type can be appropriate. The right choice depends on:
- The client’s tolerance for variability in retirement income
- Whether they plan to pay loan interest as it accrues or let it capitalize
- How much cushion the design leaves between projected and required cash value
Before illustrating, pull the product guide and answer three questions: What is the fixed loan rate, and is it participating? What index or benchmark is the variable loan rate tied to? Is the variable loan rate capped? Share those answers with your client so the illustration is understood, not just admired.

Frequently asked questions
What is the difference between a fixed and an indexed loan in IUL?
A fixed loan charges a contractually stated interest rate, so the cost is known. An indexed (variable) loan leaves the borrowed value in the index strategy and charges a variable rate, so results depend on the spread between crediting and loan interest.
What is negative arbitrage on an IUL loan?
It happens when the interest charged on an indexed loan is higher than the interest credited to the cash value. The shortfall compounds and can reduce available income or pressure the policy toward lapse.
When does an IUL wash loan become available?
Many products offer a wash or zero-cost loan after a set number of policy years, often around year 15, but timing and terms vary by carrier and product. Always confirm in the product guide.
