Types of Insurance Everyone Needs (And Some You Don't)

Insurance is fundamentally about protecting against financial catastrophe — events that could devastate your finances if they happened uninsured. The key word is "catastrophe." Insurance isn't for covering every possible inconvenience; it's for protecting against outcomes that could permanently damage your financial life.

With that framework, let's work through the types of insurance that actually matter, what coverage you need, and which products are typically not worth the cost.

The Core Principle: Insure Against Catastrophe, Not Inconvenience

A useful mental model: insurance makes sense when the potential loss is too large to self-insure (cover from savings), and when the probability isn't so high that insurance becomes unaffordable.

• Self-insure small risks: A $500 appliance repair, a minor car scratch. Pay out of pocket or from your emergency fund.
• Insure large risks: A house fire, major medical bills, disability, liability lawsuits. The potential financial damage is catastrophic — insurance is the right tool.

This principle helps explain both what you should buy and what you should skip (extended warranties, phone insurance for most people, whole life insurance for many).

Essential Insurance: Non-Negotiable

Health Insurance

The single most important insurance for most people. Medical bankruptcy is a real phenomenon in the US — even with insurance, medical bills are a leading cause of financial hardship. Without insurance, a serious illness or injury can generate bills in the hundreds of thousands.

If your employer offers health insurance: Take it. Even if the premiums seem high, group rates are typically better than what you can get individually.

If you don't have employer coverage: Options include:

• ACA Marketplace plans: Subsidies available for income between 100-400% of the federal poverty line. Check healthcare.gov for your state. Many people qualify for significant subsidies.
• Medicaid: For lower-income individuals and families. Eligibility expanded in most states.
• Short-term health plans: Cheaper but provide much less coverage. Generally not recommended except as a bridge between jobs.
• COBRA: Continue your former employer's coverage for up to 18 months after leaving a job. Often expensive but provides continuity of coverage.

What to look for: Balance premium cost against deductible, out-of-pocket maximum, and network coverage. A plan with a $0 premium but $10,000 deductible isn't actually protective unless you have $10,000 accessible.

HSA-eligible plans: High Deductible Health Plans (HDHPs) paired with a Health Savings Account provide triple tax advantages and can be excellent for healthy people who don't anticipate high medical expenses.

Auto Insurance

Required by law in almost every US state. The minimum legal requirements (liability only) protect other people if you cause an accident — not your own vehicle.

Coverage types:

• Liability (required): Pays others for injury and property damage when you're at fault
• Collision: Pays for your vehicle damage in an accident
• Comprehensive: Pays for non-collision damage (theft, weather, animal strikes)
• Uninsured/underinsured motorist: Protects you when the at-fault driver has no or insufficient insurance
• Medical payments (MedPay) / Personal injury protection (PIP): Covers your medical expenses regardless of fault

How much liability to carry: State minimums are often dangerously low ($25,000 is common). If you cause a serious accident, you could be personally sued for the difference between your coverage and actual damages. $100,000/$300,000 liability limits are commonly recommended for most drivers.

When to drop collision/comprehensive: If your car's value is low (under $4,000-5,000), collision and comprehensive coverage may cost more in premiums than the car is worth. Calculate: annual premium for these coverages vs. what you'd actually receive in a total loss.

Renters Insurance

If you rent your home, renters insurance covers your personal belongings, liability protection (if someone is injured in your home), and additional living expenses if your unit becomes uninhabitable.

Cost: $10-20/month for $30,000-50,000 in personal property coverage and $100,000 in liability. One of the most affordable protections available.

What it covers that surprises people: Your belongings are covered not just in your apartment but also from theft out of your car or while traveling. And the liability component protects you if someone slips in your apartment and sues.

Bottom line: At $15/month, renters insurance is almost universally worth having. If you don't have it, get it today — the entire setup takes 10 minutes online.

Homeowners Insurance

If you own a home, your mortgage lender requires homeowners insurance. It covers:

• Dwelling coverage: damage to the structure
• Personal property: your belongings
• Liability: if someone is injured on your property
• Additional living expenses: if you need to live elsewhere while the home is repaired

What to watch: Make sure your dwelling coverage is sufficient to rebuild (not the market value of the home, which includes land). Get a replacement cost policy, not actual cash value — actual cash value depreciates your belongings before paying out.

Flood and earthquake: Standard homeowners insurance does NOT cover floods or earthquakes. If you're in a risk zone, separate policies are needed — often required by lenders in flood zones.

Important for Many People: Evaluate Based on Your Situation

Life Insurance

Life insurance makes financial sense if other people depend on your income — a spouse, children, or anyone else who would face financial hardship if you died.

If you have no dependents, life insurance is largely unnecessary. A 25-year-old single person with no children has minimal life insurance need regardless of what insurance agents suggest.

Term life insurance: The right product for most people with dependents. Pure death benefit for a fixed term (10, 20, 30 years). Cheap, straightforward, does exactly what it's supposed to.

For a healthy 30-year-old, a $500,000 20-year term policy costs approximately $25-35/month. This is the right amount for most young parents.

How much coverage to get: A common rule is 10-12 times your annual income. The goal is to replace your income long enough for dependents to become financially independent. For a detailed comparison of the best term life companies, sample rates by age, and how to choose the right coverage amount, see our best term life insurance companies guide.

Whole life and universal life: Avoid unless you have a very specific, sophisticated estate planning reason. These products combine insurance with a savings/investment component — badly. The investment returns are poor, fees are high, and you're better off buying term insurance and investing the difference separately.

Disability Insurance

Statistically, you're more likely to become disabled during your working years than to die — yet most people have robust life insurance and no disability insurance.

Short-term disability: Replaces a portion of income (typically 60-70%) for 3-6 months. Often employer-provided.

Long-term disability: Replaces 60% of income after a waiting period (typically 90 days) until age 65 if you're unable to work in your occupation. Critical for professionals with significant income.

If your employer offers disability insurance: Take it — group rates are significantly cheaper than individual policies.

For the self-employed: Individual disability insurance can be expensive ($150-400+/month depending on coverage and occupation) but protects against the catastrophic scenario of a long-term inability to work.

Umbrella Insurance

Umbrella insurance provides additional liability coverage above your existing auto and homeowners/renters policies — typically starting at $1 million in additional coverage.

Cost: $150-300/year for $1 million in coverage. Remarkably inexpensive.

Who needs it: Anyone with significant assets (above $300,000-500,000) who wants protection against large liability claims — car accidents, slip and falls on your property, or other situations where someone sues for more than your underlying policy limits.

As your net worth grows, umbrella insurance becomes increasingly important.

What You Probably Don't Need

Extended warranties: Almost universally poor value. Consumer electronics fail at low rates in the first 1-3 years, and the premiums are priced to generate profit for the seller. If you're concerned about a major appliance, check if your credit card offers purchase protection.

Whole life insurance: Unless you have a specific estate planning need (and have confirmed this with a fee-only financial planner), term life + investing the difference is almost always superior.

Cancer-specific or disease-specific insurance: Good health insurance should cover these. Supplemental disease-specific policies are typically expensive for the coverage provided.

Credit card insurance / payment protection: Often sold alongside credit cards, covering minimum payments if you lose your job. Expensive relative to the benefit and filled with exclusions. An emergency fund is a better solution.

Mortgage life insurance: A declining death benefit policy sold by lenders that only pays off your mortgage. Term life insurance is more flexible and usually cheaper.

The Bottom Line

Focus on insuring the big, potentially catastrophic risks:

1. Health insurance: Always — medical bankruptcy is real
2. Auto insurance: Required, and carry adequate liability
3. Renters/homeowners insurance: Protects your assets and provides liability coverage
4. Life insurance: Term life if you have dependents
5. Disability insurance: Often overlooked and critically important

Skip the products designed to profit from fear of small, affordable risks. Your emergency fund handles the small stuff. Insurance handles the catastrophes.
