IUL vs Roth IRA: the ceiling is the story.
Both go in after-tax and come out tax-free — which is exactly why comparing them honestly comes down to one thing: the Roth stops at the IRS limit, and everything above it lands somewhere taxable. Model your overflow below.
Your savings goal vs the IRS ceiling.
At $1,500/mo ($18,000/yr), the Roth IRA absorbs $7,500 and $10,500 (58%) overflows into a taxable brokerage account every year.
Both market legs ride the actual S&P 500 total-return sequence (trailing 30 years, 1995–2024 data — 6 loss years en route), the brokerage overflow minus 0.75% fees and 15% long-term capital gains. IUL at 11.48% carrier-illustrated crediting with a 0% floor. Roth limit $7,500 (2026, under 50).
If your savings fit inside the Roth limit, the lines tell you the honest answer: use the Roth. The IUL case is built on the overflow.
The full side-by-side.
When the Roth IRA wins.
- Dollar for dollar, up to the limit. No insurance costs, no caps on upside, dead-simple tax treatment. If your savings fit inside the Roth ceiling, fill the Roth and stop reading.
- Simplicity. A Roth needs no design, no funding discipline, no policy maintenance. An IUL needs all three.
- Short or uncertain horizons. Roth contributions come back out anytime, tax- and penalty-free. IUL charges are front-loaded — quitting early costs real money.
When the structure wins.
- The dollars above the ceiling. Saving $1,500/month against a $7,500/year limit means most of your money overflows into taxable accounts — unless it has somewhere tax-advantaged to go.
- Income too high to contribute at all. The Roth phases out at higher MAGI. Life insurance never asks what you earn.
- Sequence protection. The 0% floor means a crash the year before retirement can’t force the plan to change.
- Protection included. The income-tax-free death benefit is there from the first premium — a Roth balance is only ever what you’ve saved.
Don’t take our word for it.
IRC §408A — the Roth IRA statute
The section that makes qualified Roth withdrawals tax-free — and sets the contribution and income eligibility rules the IRS adjusts each year.
IRS — IRA contribution limits
The current-year Roth IRA contribution ceiling and the MAGI phase-out ranges that shut the door entirely at higher incomes.
IRC §72(e) — how policy distributions are taxed
Basis-first treatment and the loan rules that make correctly designed IUL access non-taxable under current law.
IRC §7702A — the 7-pay test and MEC line
The design rule that replaces the IRS contribution cap: fund faster than the 7-pay limit and loans become taxable.
IRS Topic 409 — capital gains on taxable accounts
What the overflow dollars pay: long-term capital gains on every rebalance and sale in a brokerage account.
IRC §101(a) — the death benefit exclusion
Life insurance proceeds are excluded from the beneficiary’s gross income — the layer the Roth comparison usually ignores.
