What is term life insurance?

Term life insurance is the simplest financial product in the adult world. You pay a fixed premium every year for a set number of years (the “term”). If you die during the term, the insurer pays your beneficiary a lump sum, usually tax-free. If you don’t die, the policy ends and nobody pays anything.

That’s it. No investment component, no cash value, no savings vehicle. Pure insurance.

For most people with dependents, term is the right answer. It’s the cheapest way to guarantee that if something happens to you (always at the worst time), the people relying on your income are financially fine.

What “term” means

The term is the number of years the policy covers you. Common lengths are 10, 15, 20, and 30 years. Premiums are locked for the entire term — a 30-year policy you buy at 35 stays at the same annual price until you’re 65, even if your health changes.

At the end of the term, the policy ends. You can usually convert it to a permanent (whole life) policy or renew at much higher rates, but most people let it expire because by then they don’t need it — the kids are adults, the mortgage is paid off, and the retirement portfolio is doing the job insurance used to.

Do you even need life insurance?

Ask one question: if you died tomorrow, would anyone’s life get financially worse?

Cases where the answer is yes and you probably need term insurance:

• You have a spouse or partner who depends on your income
• You have minor children
• You have a mortgage that your household income services
• You co-signed on debts that someone else would inherit
• You have a business partner or family member dependent on your earnings

Cases where the answer is no and you probably don’t need coverage:

• Single, no kids, no dependents, adequate emergency fund
• Dual-income household where either partner could comfortably carry the mortgage alone
• Retired with enough assets to cover surviving spouse

Life insurance is income replacement, not a universal financial product. Don’t buy it because an insurance agent tells you that you need it — buy it because someone specific depends on the paycheck you currently produce.

How much coverage is enough

Two common sizing rules:

Income multiplier: 10–15× your annual income. If you earn $100k, look at $1M–$1.5M of coverage. Simple; roughly right for most households.

DIME formula (more precise):

• Debt — all non-mortgage debt
• Income — years of income replacement needed (typically until youngest child is independent)
• Mortgage — full remaining balance
• Education — projected college costs per child

Sum those four numbers. That’s the target coverage.

Example: $20k debt + ($100k × 15 years income) + $300k mortgage + ($150k × 2 kids education) = $2.12M of coverage.

Err on the high side. The premium difference between $1M and $1.5M of coverage is usually small ($10–20/month for a healthy 35-year-old). The emotional gap between “enough” and “not enough” for your surviving spouse is enormous.

How long a term

Match the term to the longest-dated financial obligation you want insured:

• Youngest child turning 22 → pick a term that covers until then
• Paying off the mortgage in 18 years → at least 20 years
• Dual-income spouse approaching financial independence → 20–25 years

Most planners recommend a 20-year or 30-year level term for parents in their 30s. Yes, 30-year premiums are higher — but you lock them in while you’re young and healthy, and if your health changes you’ll be glad you did.

Some households use a laddered approach: buy a bigger 10-year policy and a smaller 30-year policy stacked on top. Coverage is highest when obligations are largest (young kids, new mortgage) and steps down as things get paid off.

Why term beats whole life for almost everyone

Whole life, universal life, and variable life are all permanent insurance policies that combine insurance with an investment component (the “cash value”). They’re 5–10× more expensive than term for the same death benefit.

The pitch is that cash value grows tax-deferred and you can borrow against it. The reality for most buyers:

• High internal fees (often 2%+ annually) drag returns to below what a boring index fund would return
• Surrender charges lock you in for years
• The “tax-free loan” feature costs interest and reduces the death benefit
• First-year commissions to the agent are often 50–100% of your annual premium, which is why agents push it

The simple rule coined by Suze Orman and repeated by nearly every fee-only advisor: “buy term and invest the difference.” A 35-year-old paying $800/year for a $1M 30-year term policy has $4,000+/year left over vs. a whole life policy. Invested in an index fund, that $4,000/year becomes roughly $400k over 30 years — more than the whole life cash value on a comparable policy.

Whole life has narrow legitimate uses (estate tax planning for very wealthy families, funding a business buy-sell agreement). If you’re reading an intro to life insurance, none of those apply to you.

How to shop for term

The policies are nearly identical across insurers. You’re shopping on price and on the insurer’s financial strength rating (A.M. Best A- or better).

1. Get a baseline quote online from a marketplace (Term4Sale, Policygenius, Quotacy). Enter honest health info.
2. Get a medical exam. Most term policies require one — blood, urine, blood pressure, medical history. Don’t skip it if the price is significantly lower for a fully underwritten policy vs. a no-exam one. The no-exam premium is often 20–40% higher.
3. Ladder and lock. Lock the longest term you’ll need while you’re healthy.
4. Name the beneficiaries clearly. Spouse as primary, children (or a trust) as contingent. Review after every life event — marriage, divorce, child, death in family.

Rough price benchmark for a healthy 35-year-old non-smoker: $1M of 30-year level term runs about $40–60/month. Smoking doubles or triples that; recent serious health conditions can push you into higher rate tiers.

When to drop it

Drop term coverage when you’re self-insured: enough assets that your death no longer creates financial hardship for anyone. For most households this aligns with hitting retirement savings targets and paying off the mortgage.

A common pattern: 30-year term policy purchased in your 30s, cancelled or allowed to lapse in your 50s or 60s once the portfolio and paid-off home make further coverage unnecessary.
