Is an IUL better than a Roth IRA?

For most people building retirement savings, a Roth IRA is simpler, cheaper, and has no insurance costs, so it usually wins on pure growth. An IUL adds a death benefit and has no income limits, which can matter for high earners who've already maxed a Roth. They serve different primary jobs, so 'better' depends on your goal.

What is MPI, and how does it compare to a Roth IRA?

MPI (Maximum Premium Indexing) is a trademarked marketing name for one way of designing an IUL: the policy is funded close to the IRS maximum, and a participating policy loan is used to borrow against the cash value while it stays credited. It is still an IUL, with the same caps, fees, and cost of insurance. The borrowing adds leverage: if index credits beat the loan rate it helps, but if they fall short the loan grows faster than the cash value and can push the policy toward lapse and a tax bill. The 0% floor protects index credits, not the loan. A Roth IRA has none of that complexity, so most people should fill a Roth first and treat MPI as a later layer, if at all.

Should I drop my Roth IRA to fund an IUL?

Generally no. A common order of operations is to capture any employer match, then max a Roth IRA or do a backdoor Roth if income-limited, before considering an IUL as a later layer for someone with a permanent insurance need and extra cash flow. Be cautious of any pitch to replace a Roth with an IUL.

Can high earners use both?

Yes. High earners often use a backdoor Roth to keep funding tax-free growth and may add an IUL on top once other tax-advantaged accounts are full and a permanent death-benefit need exists. They complement each other more than they compete.

What are the 2026 Roth IRA income limits?

For 2026, the ability to contribute directly to a Roth IRA phases out between $153,000 and $168,000 for single filers and between $242,000 and $252,000 for married couples filing jointly. Above the top of the range you are shut out of direct contributions and would use a backdoor Roth instead.

IUL vs Roth IRA: which is better?

This comparison gets pitched as a head-to-head, often by someone selling one side. The honest framing: they share a feature (tax-free access), but they’re built for different jobs. Here’s where each wins.

What they share

Both can deliver tax-free money in retirement — a Roth IRA through qualified withdrawals, an IUL through policy loans against cash value. That single overlap is why they’re compared. Almost everything else is different.

How they actually differ

Primary job: Roth IRA → retirement growth. IUL → a death benefit, with cash value as a secondary feature.
Cost: A Roth IRA holding index funds has minimal cost. An IUL carries insurance charges and fees that rise with age — a real drag on growth.
Contribution limits: The Roth IRA has an annual cap and income limits. An IUL has no IRS contribution cap or income phase-out (within insurance funding rules).
Upside: A Roth IRA in index funds gets the market’s full return (and full downside). An IUL caps the upside in exchange for a floor.
Guarantees: Neither guarantees market returns, but the IUL’s floor limits crediting losses; a Roth IRA’s value can fall with the market.
Liquidity: Roth contributions can be withdrawn anytime tax- and penalty-free. IUL has surrender charges in the early years.

	Roth IRA	IUL
Primary job	Retirement growth	Death benefit; cash value secondary
Cost	Minimal (index funds)	Insurance charges + fees, rising with age
Contribution limit (2026)	$7,500 ($8,600 if 50+)	No IRS cap (within funding rules)
Income limit (2026)	$153k–168k single / $242k–252k MFJ	None
Downside protection	None — falls with the market	Floor (often 0%) limits losses

The order of operations most planners use

For the typical saver: capture the full 401(k) match first, then max a Roth IRA (or a backdoor Roth if you’re over the income limit). Only after those — and only with a genuine permanent insurance need and spare cash flow — does an IUL become a sensible additional layer. This is the tax-diversification logic: build the cheap tax-free bucket first.

When the IUL side has a point

For a high earner who has already maxed every tax-advantaged account, the Roth front door is closed by income and even the backdoor is full, an IUL’s lack of contribution limits plus a death benefit can genuinely add something — the core idea behind a life-insurance retirement plan. That’s a narrow, real use case, not a universal one.

The bottom line

If you’re choosing one, a Roth IRA is the better default for most people: cheaper, simpler, more flexible. An IUL isn’t a Roth replacement — it’s a different tool for people who’ve outgrown the Roth’s limits and want lasting insurance too.
