Max-Funded IUL Design: How to Solve for Maximum Cash Accumulation

Who this is for: Anyone buying IUL for accumulation who wants to know what “max-funded” actually means on the illustration.

The core idea: minimum death benefit, maximum premium

Cost of insurance is charged on the net amount at risk — death benefit minus cash value. A smaller death benefit relative to the premium means a smaller charge, and more of each dollar stays in cash value. So an accumulation design starts from the premium you intend to pay and solves for the smallest death benefit the tax rules allow for that premium without the policy becoming a MEC. That’s the whole trick, and it’s why “solve for minimum non-MEC death benefit” is the phrase to say to your agent.

The supporting choices

Death benefit option: many designs use an increasing death benefit (option B, where the benefit equals the face amount plus cash value) during the funding years to keep the policy under the MEC and guideline limits, then switch to a level benefit (option A) when funding stops, dropping the net amount at risk — and the costs — for the loan years. Riders: skip the ones you don’t need; each has a cost. Index strategy: understand the cap and participation rate on the strategy chosen, and know they can change. Funding schedule: near the maximum every year for as long as the plan requires, not the minimum in lean years.

What to demand from the illustration

The guaranteed column at your premium with the policy surviving past age 90. The same design run at a meaningfully lower illustrated rate. The cost-summary pages. The MEC premium and the guideline premium stated plainly. And a version with a larger death benefit for comparison, so you can see what the accumulation design saves in cost. A carrier’s software can produce all of these in minutes; an agent who won’t is telling you something.

The essentials

What actually matters here

Solve for the minimum non-MEC death benefit

Start from the premium and let the tax rules set the smallest allowable benefit. Lower amount at risk, lower cost, more cash value.

Increasing, then level

Option B during funding to stay under the limits; switch to option A when funding stops to cut costs in the loan years.

Fund near the maximum, every year

The design only works when the premium actually shows up. Minimum funding turns a max-accumulation design into a lapse.

Hypothetical — mechanics only, not a projection

Same premium, two designs (hypothetical)

A 40-year-old commits a hypothetical $15,000 a year for 20 years. Design A: a $1,200,000 level death benefit — large amount at risk, high cost of insurance, less cash value. Design B: the minimum non-MEC death benefit for that premium — perhaps in the $450,000 range depending on carrier and age — with an increasing option during funding, switched to level afterward. Design B’s costs are a fraction of Design A’s, so far more of the $300,000 of premium becomes cash value. The exact figures depend on the carrier, age, health, and product; the direction never changes.

Illustrative assumptions chosen to explain how the mechanics work. Not a projection, guarantee, or illustration of any actual policy; real caps, costs, and results vary by carrier and change over time.

IUL can genuinely fit when…

Accumulation is the primary goal and protection is handled elsewhere
You can fund near the maximum for the full schedule
You’ll switch death benefit options at the right time with your agent
You’ve seen the design at guaranteed and reduced rates

Slow down when…

The proposal leads with a big death benefit “for the protection”
You can’t commit to the funding schedule
Nobody mentioned the MEC premium or death benefit options

Straight answers

Questions people actually ask

What does “max-funded IUL” mean?

A policy designed to accept the largest premium the tax rules allow without becoming a MEC, paired with the smallest death benefit that supports that premium. The small death benefit keeps costs low; the large premium builds cash value. It’s the accumulation-oriented design, as opposed to a policy designed to maximize the death benefit for a given premium.

Why does a lower death benefit mean more cash value?

Because cost of insurance is charged on the net amount at risk — death benefit minus cash value. A smaller death benefit means a smaller monthly charge, so more of each premium stays in the account and compounds. Two policies with identical premiums and different death benefits accumulate very differently for exactly this reason.

What is the difference between death benefit option A and option B?

Option A (level) pays a fixed face amount; as cash value grows, the net amount at risk shrinks and so do costs. Option B (increasing) pays the face amount plus the cash value; it’s often used during funding years to keep the policy within the MEC and guideline limits, then switched to option A when funding stops to reduce costs for the loan years.
