A healthy 40-year-old can buy a 20-year $500,000 term life insurance policy for about $25/month. That same coverage as whole life insurance would run $400/month. The $375 monthly difference, invested in VTSAX at 7%, compounds to $193,000 over 20 years. Term life plus investing beats whole life mathematically in almost every scenario.
Term life is simple: you pay a fixed premium for a specified period (10, 15, 20, 30 years), and if you die during that term, your beneficiaries receive the face value. No investment component, no cash value, no complexity. It's pure insurance — the product industry insurers make the least commission on and the product consumers usually need.
The Basic Structure
Term life components:
- Face amount: the death benefit ($500K, $1M, etc.)
- Term length: how long coverage lasts (10, 15, 20, 25, 30 years)
- Premium: fixed monthly or annual cost
- Eligibility: based on age, health, smoking status, occupation
Once the term expires, so does coverage. Most term policies have conversion options to whole life (rarely worthwhile) or renewal options at new age-based rates (expensive).
The Pricing Reality
For non-smoking healthy applicants:
| Age | 20-year $500K | 20-year $1M |
|---|---|---|
| 30 | $18/month | $28/month |
| 40 | $25/month | $42/month |
| 50 | $65/month | $110/month |
| 60 | $190/month | $340/month |
Smokers pay 2-3x. Pre-existing conditions raise rates. Heavier builds raise rates. Dangerous hobbies (skydiving, rock climbing) raise rates.
How Much Coverage You Need
The traditional rule: 10-12× annual income. For a $100K earner: $1M-$1.2M coverage.
Better formula — specific income replacement analysis:
- Annual income × years to dependents' independence (kids graduating college)
- + mortgage payoff amount
- + college funding goals
- + estate tax considerations
- - existing assets available to survivors
For a 35-year-old with two young kids, $150K income, $400K mortgage: maybe $2M coverage for 20 years. Costs about $65/month for a healthy non-smoker.
The Term Length Decision
How long do you need coverage? Generally:
- Until kids are financially independent (usually college graduation)
- Until mortgage is paid off
- Until you've accumulated sufficient savings that survivors don't need insurance proceeds
For most 30-year-olds: 25-30 year term covers until kids are adults and wealth is built.
For most 40-year-olds: 20-year term usually sufficient.
For most 50-year-olds: 15-year term, possibly 20 if kids are still young.
Longer terms cost more but provide certainty. Short terms risk needing replacement coverage at higher future rates.
The Buy-Term-Invest-the-Difference Math
Consider a healthy 40-year-old comparing:
Whole life $500K: $400/month ($4,800/year)
Term life 20-year $500K: $25/month ($300/year)
Difference: $4,500/year invested for 20 years at 7% = $186,000
After 20 years:
- Whole life: $500K death benefit, roughly $120K cash value
- Term + investing: $500K insurance (only while term active) + $186K investment assets
Term + investing wins. You have equivalent coverage during working years and substantially more wealth.
When term expires at 60, you're self-insuring — you have enough assets that life insurance is no longer critical. This is the target.
When You Don't Need Life Insurance
If you have no dependents (no spouse, no kids), you probably don't need life insurance. Life insurance replaces income for people who depend on your income. If nobody depends on you, save the premium.
Exceptions:
- Significant debts (business loans, personal loans) that pass to others
- Aging parents you support financially
- Specific estate planning considerations
For most single, childless earners under 30, life insurance is unnecessary expense.
The Quote Shopping
Term life rates vary meaningfully across insurers. Shop:
- Policygenius: compares 20+ insurers at once
- Haven Life: direct online application, often fastest
- Ladder Life: digital-first, easy application
- Term4Sale.com: comparison tool across direct providers
Don't accept the first quote. Rate differences can be 30%+ between insurers for identical coverage.
The Medical Underwriting
Most term life applications require:
- Medical exam (height/weight, blood draw, urine)
- Detailed health questionnaire
- Prescription drug history
- Lifestyle questions (smoking, drugs, alcohol, driving record)
Rates depend on "health classification": Preferred Plus, Preferred, Standard Plus, Standard, Substandard. Difference between Preferred Plus and Standard can be 30%+ on premium.
Lock in rates while healthy. A diagnosis later can dramatically raise rates or eliminate eligibility.
The No-Exam Options
"Simplified issue" and "accelerated underwriting" policies skip the medical exam. Faster approval (days vs. weeks) but typically 20-40% higher premiums.
For younger applicants without concerns about health history, the traditional exam route saves money. For older applicants or those with health issues, simplified issue avoids denial risk.
The Group Life Insurance Trap
Your employer probably offers 1-2x salary in life insurance. This is usually nominal (not enough coverage for most families) and tied to employment (ends when you leave).
Don't rely on employer life insurance as primary coverage. Have independent term coverage that doesn't depend on employment.
The Bottom Line
Term life insurance solves a specific problem: income replacement during years when dependents rely on your income. It's inexpensive, simple, and sufficient for most families.
Buy level-premium term equal to 10-15x annual income for 20-25 years. Invest the difference vs. what whole life would have cost. This combination beats any "permanent" life insurance product for the vast majority of earners.
Simplicity wins again.
