Term life vs. whole life — the real-world IRR comparison
Whole-life policies look compelling in a sales illustration. In almost every realistic scenario, a plain term policy paired with low-cost index funds beats them on after-fee IRR.
The pitch, in one paragraph
A whole-life agent will show you a glossy illustration where your policy cash value compounds tax-deferred and "replaces your bond allocation". The hook is real: the death benefit is permanent, the cash value grows, and you can borrow against it. In exchange you pay 8-12× what a comparable term policy would cost, and the first several years of premium are consumed almost entirely by commissions and carrier overhead.
What the math actually shows
Run a side-by-side simulation of two 35-year-olds, both buying $500,000 of coverage:
- Agent A buys a $500k whole-life policy for ~$6,000/year.
- Agent B buys a $500k 20-year term policy for ~$360/year and invests the $5,640 difference into a 70/30 index portfolio returning 6.5% real.
After 20 years, Agent A has roughly $110,000 in cash-value surrender value. Agent B has roughly $225,000 in an index account. Both still have the $500k death benefit over that window. Agent B wins by a factor of 2× on liquid capital AND keeps control of the account.
The whole-life sales illustration conveniently stops the comparison the moment the term policy "expires". In reality, 95% of people don't need the death benefit at 55 — their kids are grown, the mortgage is paid, and the retirement account is doing the work. The permanence being sold is the permanence of the commission stream.
When whole-life is actually defensible
Three narrow cases:
- Estate planning for genuinely rich households. If your net worth exceeds the federal estate-tax exemption and you want a tax-free liquidity source to pay the eventual estate tax, a properly-structured whole-life policy inside an ILIT can work. This is a $20M-net-worth problem, not a $500k problem.
- A dependent you'll support for life. A disabled child, an aging parent in your care, a spouse with a complex medical situation — any dependent whose financial need will outlast your working life makes a permanent death benefit genuinely rational.
- You have maxed every tax-advantaged account and want more tax deferral. A rare case, usually for very-high-income professionals who've filled 401(k), IRA, HSA, and 529s and are looking for one more deferral bucket. Even here, a direct taxable brokerage usually wins over a 20+ year horizon.
The upsell to watch for
If an agent leads with "you can borrow against the cash value tax-free" — walk out. The loan is real but it comes with 4-8% interest, and if the policy lapses while a loan is outstanding, the borrowed amount becomes immediately taxable income. "Infinite banking" schemes are built on that line and they've generated more consumer-protection complaints than any other life-insurance strategy of the last decade.
Frequently asked
Should I cash out a whole-life policy I already own? Not necessarily. If you're more than 10 years in, the heaviest commission drag has already happened and future returns begin to look respectable. Pull a current in-force illustration and model the next 10 years before cancelling.
What term length should I pick? Match it to the window your dependents still need you — 20 years if your youngest is 5, 30 years if your youngest is a newborn. Term policies get materially harder to underwrite in your 50s, so lock a long term while you're under 40 if you can.
