The 12 insurance policies, ranked from essential to skip

Insurance has one legitimate job: transferring risks you cannot absorb to a company that can. Everything else sold under the name is prepayment with a markup. That single principle — insure against ruin, self-insure against annoyance — sorts the entire industry. Here are twelve common policies ranked from essential to skip, with the reasoning made explicit so you can re-run the ranking for your own life.

The essential tier (1–5): ruin insurance

Health insurance is rank one because unhedged medical risk is unbounded — a single hospitalization can exceed a lifetime of savings, and medical debt remains a leading contributor to American bankruptcies. Auto liability is second for the same shape of reason: you can total your own car and survive financially, but injuring someone else creates liability with no ceiling. Homeowners insurance protects most families' largest asset; renters insurance, at $15–$30 a month, is the cheapest essential on the list and skipped by roughly half of renters who assume the landlord's policy covers their belongings (it doesn't — it covers the building). Term life belongs in the tier the day someone depends on your income, and not one day before.

Rank 4 deserves its own paragraph

Long-term disability is the most important policy Americans don't buy. The Social Security Administration estimates that roughly one in four of today's 20-year-olds will experience a disability before retirement age — the odds dwarf the odds of dying young, yet term life outsells private disability coverage massively. Your income is your largest asset by far: a 30-year-old earning $70,000 with normal raises will earn $4–5 million before 65, and disability insurance is the policy on that. Employer plans often cover only 50–60% of base salary, taxed if the employer paid the premium. Check yours; supplement it if it's thin; prioritize 'own-occupation' definitions if you're a specialist.

The judgment tier (6–9): math, not dogma

Umbrella liability — $1 million of coverage above your auto and home limits for $200–$400 a year — becomes near-essential once your net worth exceeds your underlying policy limits; it's the cheapest ruin-protection per dollar in the industry. Collision and comprehensive on your car is a straight calculation: on a $30,000 vehicle it's clearly worth it; on a $3,500 beater, paying $800 a year plus a $500 deductible to protect $3,500 of value stops making sense — drop it and bank the premium. Long-term care insurance addresses a real risk (a private nursing room can run over $100,000 a year) with a flawed product line — premiums have historically jumped even on existing policyholders; the honest advice is to evaluate hybrid policies and self-insurance capacity in your mid-50s rather than defaulting either way. Travel medical and evacuation coverage is cheap and legitimate for international trips because most domestic health plans cover little abroad — it's the trip-cancellation add-ons that are usually poor value, not the medical piece.

The skip tier (10–12): peace of mind, retail price

Extended warranties and device insurance fail the ruin test — a broken phone is an annoyance, not a catastrophe — and they're priced as profit centers, which is why the cashier is required to offer them. Accidental death & dismemberment pays only if you die accidentally, a small subset of a risk term life already covers entirely; it survives on the psychology that 'accidental' sounds like the scary kind of death, when illness is overwhelmingly more likely. Credit card and loan 'payment protection' is the worst product on the page: coverage that often costs 1%+ of your balance monthly (a 12%+ annual drag), pays narrowly, and duplicates what a term policy and an emergency fund do better and cheaper. As a family, these products share a tell: they're sold at checkout, in enrollment packets, and by mail — sold to you, never bought by anyone on purpose after an hour of research.

The bottom line

Ranked honestly, insurance splits into three tiers: policies against ruin (health, liability, home, disability, term life for parents — buy them, with high deductibles and high limits), policies that are math problems (collision, long-term care, travel medical — run your numbers), and policies against inconvenience (warranties, AD&D, balance protection — skip them and self-insure). The industry earns its worst margins on the third tier and its keep on the first. Buy insurance the way the actuaries do: coldly, against catastrophe only — and let your emergency fund handle everything small enough to have a price tag.
