Whole life vs term life vs IUL.
The honest comparison.
Whole life and IUL policies are sold as investments. They are not. Here is the honest math on how they compare to buying term life and investing the difference.
US-only. Insurance products and tax treatment are US-specific. The general principle (term + index investing beats permanent insurance for most people) applies in most countries.
The phrase "buy term and invest the difference" exists because it almost always wins the math. Whole life and IUL policies have very high commissions for the agent, which tells you who they benefit most. The legitimate use cases for permanent insurance (estate liquidityliquidityHow quickly and easily you can convert an asset to cash without significantly affecting its price.Full definition for very high net worthnet worthEverything you own (assets) minus everything you owe (debts). The most comprehensive measure of financial health.Full definition, lifetime care for special-needs dependents) do not apply to most people.
Section 1 · Term life
- Fixed premium for a specific period (10, 20, 30 years).
- If you die during the term: your beneficiaries receive the death benefit.
- If you live: the policy expires.
- No cash value. No investment component.
- Lowest cost per dollar of coverage.
Who needs term life: anyone with dependents who rely on their income, or anyone with cosigned debt (mortgage) and a partner who could not cover it alone. Who does not: people with no dependents, or people whose assets exceed their obligations.
Section 2 · Whole life
- Permanent coverage, does not expire if you keep paying premiums.
- Part of your premium goes into a "cash value" account that grows at a specified rate.
- Cash value can be borrowed against or surrendered.
- Death benefit is guaranteed as long as premiums are paid.
The catches
- Premiums are 5-15x higher than comparable term coverage.
- Guaranteed cash-value growth rate is typically 2-4%, less than long-term stock-market returns.
- High commission structure for agents, often 50-100% of the first year's premium verify×DON'T TRUST, VERIFYClaim: Whole life insurance commissions can range from 50 to 100%+ of first-year premium.Verify at: National Association of Insurance Commissioners ↗ · Consumer Reports analysis ↗Industry commissions are documented across multiple consumer-protection sources. Specific figures vary by carrier and policy type..
Section 3 · Indexed Universal Life (IUL)
A variation of universal life insurance (flexible premiums, permanent coverage) where cash-value growth is tied to a stock-market index (usually S&P 500) but with a floor and a cap.
Typical structure
- Floor: 0% (you cannot lose in a down year).
- Cap: 8-12% (you do not capture full market returns in a great year).
The reality
- The cap means you miss the best years.
- The 0% floor does not account for inflationinflationA general increase in prices over time, meaning each dollar buys less than it did before.Full definition. "0% return" in a 3% inflation year is a real loss.
- Fees and insurance costs are deducted from the cash-value account.
- Complex and difficult to compare accurately.
Section 4 · The term + invest the difference math
$500,000, 20-year term for a healthy 35-year-old: approximately $25-$40/month. Comparable whole-life policy: approximately $350-$500/month. Difference: approximately $325/month.
- Term + invest difference: approximately $204,000 in the brokerage account, plus the term policy in force.
- Whole life cash value at 3%: approximately $107,000.
- Difference: approximately $97,000 in your favor with term + invest verify×DON'T TRUST, VERIFYClaim: $325/month at 7% over 20 years = ~$204K. At 3% = ~$107K.Verify at: Compound interest calculator ↗FV = PMT × [((1+r)^n - 1) / r]. Annual compounding..
In almost every scenario for a healthy person in their 30s-40s, term plus investing the difference wins, often by a wide margin.

- Business succession planning where insurance funds a buy-sell agreement.

For most people with a typical situation, these use cases do not apply.
