Insurance Types and Coverage

Insurance is a tool for transferring tail risk — events that are too expensive to absorb out of pocket, too unpredictable to plan for, and too rare to make self-funding sense. The right framework: *buy enough insurance to protect against ruin; skip the rest*. The insurance industry markets aggressively against this principle because the policies that protect against ruin tend to be cheap (low commissions) and the policies that protect against minor inconveniences tend to be expensive (high commissions).

This page is the full map: what coverage exists, what it does, and where each type sits on the "essential / optional / usually skip" spectrum.

The essential layer

Coverage almost every household should have at adequate limits.

Health insurance

The single largest financial risk in the US. A serious medical event without coverage routinely produces six-figure bills; a serious event with bad coverage can still produce ruinous bills.

**What to look at when choosing**:

- **Premium** — what you pay each month

- **Deductible** — what you pay before coverage kicks in

- **Out-of-pocket maximum** — your worst-case annual cost

- **Network** — which providers and hospitals are covered

- **HSA eligibility** — high-deductible plans enable HSA contributions, which is the most tax-advantaged account in the US system

**Common error**: choosing the lowest-premium plan without modeling expected medical use. A high-deductible plan saves money for the healthy and costs more for the chronically-ill.

Auto liability insurance

Required in most states. Covers your liability if you cause an accident that injures someone or damages their property.

**Recommended minimums**:

- Bodily injury liability: at least 100/300 ($100K per person, $300K per accident); 250/500 is better

- Property damage liability: at least $100K

- State minimums (often 25/50/25 or worse) are dangerously low; the cost of doubling them is small

Add comprehensive and collision if the car has meaningful value; skip both on cars worth less than $5K (the deductibles often exceed the payout).

Renters or homeowners insurance

For renters: typically $15–$25/month. Covers personal property and provides liability protection. Almost universally worth it.

For homeowners: typically $1,000–$3,000/year depending on location, replacement value, and risk profile (flood, fire, hurricane zones). Required by mortgage lenders.

**The replacement-cost trap**: many policies cover "actual cash value" (depreciated value) by default. Pay the modest extra to upgrade to "replacement cost" — actual cash value of a 10-year-old roof is far less than a new one.

Term life insurance (if anyone depends on your income)

Covered in detail at [LifeInsuranceTypes](LifeInsuranceTypes). Term, scaled to your obligations, is the right answer for ~95% of households.

Long-term disability insurance

The most under-purchased important coverage. Statistics: a 35-year-old has roughly a 1-in-4 chance of being disabled for 90+ days at some point during their working years. The financial impact of long-term disability — lost income for years or decades — often exceeds the impact of premature death.

**Sources**:

- **Employer LTD coverage** — many employers offer it free or cheap. Take it. Coverage typically replaces 50–60% of income up to a cap.

- **Individual LTD policy** — supplement employer coverage if your income is well above the employer's cap, or if you might leave the employer.

**Key features to look at**:

- Definition of disability — "own occupation" (covers if you cannot do your specific job) is much better than "any occupation" (covers only if you cannot do any work)

- Elimination period (90 or 180 days is typical)

- Benefit period — to age 65 is the standard

- Cost-of-living adjustment

The optional-but-strongly-recommended layer

Coverage that depends on circumstances but should be evaluated explicitly.

Umbrella liability policy

A separate policy that adds $1M+ of liability coverage on top of your auto and home policies. Coverage costs roughly $200–$400/year per million.

**Buy it if**:

- Net worth above ~$500K

- Teenage drivers in the household

- Pool, dog, or other heightened-risk feature on the property

- Public-facing profession (doctor, lawyer, anyone who might be sued)

The math is asymmetric: a single serious auto accident can produce a judgment that exceeds your auto liability limit. The umbrella covers the gap. At ~$300/year per $1M of additional coverage, it is one of the most cost-effective insurance products available.

Health savings account contributions (with HDHP)

Not strictly insurance but worth mentioning. If you choose a high-deductible health plan, max your HSA contributions. The HSA is the only account that is tax-deductible going in, tax-deferred while invested, and tax-free coming out for medical expenses. After age 65, withdrawals for non-medical purposes are taxed but not penalized — effectively a backup retirement account.

Long-term care insurance (in retirement)

Covered in detail at [LongTermCareInsurance](LongTermCareInsurance). The case is real but narrow: net worth in the $500K–$2.5M range, age 55–65, healthy.

Earthquake or flood insurance (location-specific)

Standard homeowners policies usually exclude both. If you live in an earthquake zone (CA, AK, parts of WA/OR) or flood zone (FEMA zones A and V), evaluate separately.

The case-by-case layer

Coverage that depends heavily on circumstances and warrants explicit analysis.

Disability insurance for self-employed / business owners

If your income is highly dependent on a specific business, consider:

- Disability insurance with sufficient coverage for the business's loss

- Key-person insurance if employees depend on you

- Buy-sell agreement funding

Professional liability (errors and omissions)

Required in many professions (medical, legal, accounting). Often required by clients in consulting work.

Pet insurance

The math is mixed. For young, healthy pets, premiums roughly equal expected payouts; you are not winning by buying. For specific breeds prone to expensive conditions, the math can favor coverage. Self-funding via a dedicated savings account is a reasonable alternative.

Gap insurance for car loans

If you owe more on a car than its current value (common in years 1–3 of a loan), gap insurance covers the difference if the car is totaled. Worth it on new-car loans where this exposure is high; not needed once equity is positive.

The usually-skip layer

Coverage that is sold heavily but rarely worth buying for most households.

Whole life and universal life insurance

Marketed as investments, sold as insurance. The internal rate of return is typically 2–4% over decades. See [LifeInsuranceTypes](LifeInsuranceTypes) for the full analysis. For most households, term-plus-invest dominates.

Specific-disease insurance (cancer, heart disease)

If you have decent health insurance, these policies duplicate coverage you already have. The marketing exploits fear; the math is bad.

Extended warranties

Almost universally bad value. Manufacturers know failure rates and price warranties to be profitable for them. The exception is occasional cell phone protection plans on high-end devices, where breakage rates and replacement costs make the math closer.

Accidental death and dismemberment (AD&D)

Pays only for very specific causes of death. Standard term life covers everything AD&D does, plus much more. If you have term life, AD&D is redundant.

Mortgage insurance (private MI vs. mortgage life insurance)

- **Private mortgage insurance (PMI)** — required by lenders if you put less than 20% down. Not optional, but cancelable once you reach 20% equity. Different category.

- **Mortgage life insurance** — pays off the mortgage if you die. A worse, more expensive version of term life. Use term life instead.

Credit-card-offered insurance

Card-issuer-marketed coverage for travel cancellation, rental car damage, lost luggage. Sometimes cheap, sometimes redundant with what your card provides automatically. Read what your card already covers before paying for upgrades.

Identity theft insurance

Often duplicates services you already have via free credit monitoring or your credit card. The actual financial liability of identity theft is limited by federal law on most accounts. The "service" component (helping you fix the damage) is the real value, and it is often free elsewhere.

How much liability coverage is enough?

A common framework: total liability coverage (auto + home + umbrella) should at least equal your net worth, plus a buffer for future earnings. If you have $400K of net worth and $80K of annual income, target $500K–$1M of total liability coverage.

The reasoning: a serious lawsuit can take everything you have plus garnish future earnings. Insurance limits cap your exposure.

Annual review

Once a year, walk through the full insurance stack:

1. **What changed in the household?** New child, new house, new income level, new dependents, new health condition.

2. **Are coverage levels still appropriate?** Income up → life insurance up. Net worth up → liability coverage up.

3. **Are beneficiaries current?** Marriage, divorce, deaths in the family — beneficiary designations are easy to forget.

4. **Are premiums still competitive?** Auto and home insurance especially can drift; rate-shop every 2–3 years.

5. **Did anyone get a better employer plan?** Switching health insurance through a job change often warrants reviewing all related coverage.

Common failure patterns

- **Insuring too low.** State-minimum auto liability is dangerous; underinsured homes, underinsured for life. Premium savings on inadequate coverage rarely justify the gap exposure.

- **Insuring too much for minor risks.** Pet insurance, extended warranties, AD&D, identity theft. The premiums add up and expected value is poor.

- **Not stress-testing the deductible.** A $5,000 deductible is fine if you have an emergency fund; a problem if you do not.

- **Ignoring beneficiary designations on retirement accounts.** Beneficiary designations supersede wills. Outdated beneficiaries are one of the most common estate-planning failures.

- **Letting coverage lapse during transitions.** Job change, move, new car — these are the moments coverage falls through. Specifically check.
