Guide to Insurance You Actually Need

The one rule

Insurance exists to protect you from things you can’t recover from. That’s it. Everything else — extended warranties, “accident protection plans,” identity theft monitoring — is a budget item dressed up like risk management.

The test: if this thing happens and I’m not insured, can I write a check and move on? If yes, you don’t need insurance for it. If no, you do.

A $200 phone screen — write a check, move on. A $30,000 surgery — that’s what insurance is for.

This is the lens for the rest of the guide.

The hierarchy for young adults

In rough priority order:

1. Health — non-negotiable
2. Auto — legally required if you drive
3. Renters — cheap, almost always worth it
4. Disability — the most-overlooked, most-relevant policy for young adults
5. Term life — only if someone depends on your income
6. Umbrella — later, once net worth grows

And things to skip:

• Whole / universal / variable life — almost always the wrong answer
• Extended warranties on phones, appliances, cars
• Rental car damage coverage if your credit card already includes it
• Identity theft insurance — mostly redundant with what’s already free

1. Health insurance

Skipping health insurance because “I’m young and healthy” is the most expensive bet on the planet. Without insurance, an appendicitis surgery is billed at $30K–$60K. A car accident with a hospital stay is six figures. Cancer is bankrupting.

The actual decision is which plan, not whether to have one. The two main shapes:

• HDHP (high-deductible health plan) — lower monthly premium, higher deductible, eligible for an HSA. Best for healthy people who rarely see doctors.
• PPO (preferred provider organization) — higher premium, lower deductible, no HSA eligibility. Best for people with ongoing prescriptions or specialist care.

Run the math both ways every open enrollment. The right answer changes as your life changes.

The HDHP wins more often for young adults than people realize, because of the HSA — see the Guide to HSAs for the full picture. The HSA is what turns “I have to pay my full deductible before insurance kicks in” (typically $2,500–$5,000 on real-world HDHPs, with $1,700 the IRS-required floor) into “and that deductible was paid with pre-tax dollars.”

2. Auto insurance

Most states require it; all states make it a bad idea to skip. The four main coverage types you’ll see on a quote:

• Liability — pays for damage you cause to others. Required by most states. The state minimums (e.g., 25/50/25) are low; in a serious accident, you’re personally on the hook for anything beyond the minimum. Most planners suggest 100/300/100 at minimum.
• Collision — pays for damage to your car in an accident, regardless of fault. Worth carrying as long as your car is worth more than ~$3,000–$5,000.
• Comprehensive — pays for non-collision damage (theft, hail, falling tree). Often pairs with collision and is cheap.
• Uninsured/underinsured motorist — pays for damage to you when the other driver doesn’t have enough coverage. Surprisingly common; carry it.

Skip:

• New-car replacement unless you have a brand-new car and care.
• Roadside assistance if you have it through AAA, your card, or the manufacturer.
• Rental car coverage if you almost never need a rental.

Bigger deductibles → lower premiums. If you have a real emergency fund, take a $1,000 deductible instead of $250 and pocket the savings every month.

3. Renters insurance

Renters is one of the highest-ROI insurance policies you’ll ever buy. Typical cost: $10–$25 a month. Typical coverage: $20K–$50K of personal property, $100K–$300K of liability.

What it actually covers:

• Personal property — your stuff, if it’s stolen, burned, or damaged.
• Liability — if someone is hurt at your place, or you damage someone else’s apartment (overflowing tub, kitchen fire that spreads).
• Loss of use — hotel stays if your apartment is uninhabitable after a covered loss.

Most landlords now require it as part of the lease. Even where they don’t, get it. The single time you’ll need it (kitchen fire, theft, neighbor’s pipe burst into your place) pays back every premium you’ve ever written.

4. Disability insurance — the one nobody talks about

Here’s a number that surprises people: per the Social Security Administration, more than 1 in 4 of today’s 20-year-olds will become disabled before reaching retirement age — roughly twice the rate they’ll die before then. And the financial impact is similar to dying: your income stops either way.

Yet disability insurance is almost never on a young adult’s radar.

Two flavors:

• Short-term disability (STD) — covers 3–6 months. Often offered through employers, cheap, fills the gap until long-term kicks in.
• Long-term disability (LTD) — covers months to decades. The one that actually matters. Aim to replace ~60%–70% of your gross income; that’s typically the maximum benefit insurers will write.

If your employer offers LTD, take it. The group rate is usually a fraction of what you’d pay individually. Important: if your employer pays the premium, the benefits are taxable. If you pay the premium with after-tax dollars, the benefits are tax-free. That alone often justifies paying for it yourself even when employer-subsidized — a 60% tax-free benefit can replace 80%+ of your prior take-home, while a 60% taxable benefit lands much closer to 45–50%.

Outside of work, individual long-term disability policies cost ~1%–3% of income. For someone making $60K gross, that’s maybe $50–$150/month for a policy that protects the next 30+ years of earnings.

5. Term life insurance — only if someone depends on your income

If you die tomorrow, does someone’s life become financially worse? If yes, you need life insurance. If no, you don’t.

For most young adults — single, no kids, no co-signed debt — the honest answer is no. You don’t need life insurance yet. Don’t buy it because someone says “you should lock in low rates while you’re young.” That’s a sales pitch, not advice.

For the cases when you do need it: term life, almost always. Term life is simple — you pay a fixed premium for a fixed term (10, 20, 30 years), and if you die during the term, your beneficiaries get a lump sum. If the term ends and you’re still alive, the policy expires and that’s fine.

How much: 10–12× your annual income is the standard rule of thumb. For a 30-year-old non-smoker making $60K, a $750K 20-year term policy is often $25–$40 a month.

What to skip: whole / universal / variable life

These are policies that combine a life insurance benefit with an investment component — sometimes called “permanent” or “cash value” life insurance. They’re sold aggressively because they pay big commissions to the agent (often 50%–100% of the first year’s premium).

For ~95% of people, they’re the wrong answer. Three reasons:

1. The cost. A whole life policy for the same coverage is typically 5×–10× the cost of a term policy. The “extra” goes into the cash value, but slowly — most of the early years’ premiums go to fees and commissions.
2. The investment is mediocre. Cash value grows at 2%–4% on average — meaningfully below what the same dollars would earn in a low-cost index fund.
3. The use case is narrow. Whole life is genuinely useful for high-net-worth estate planning where you’ve already maxed every other tax-advantaged account. That’s a small slice of the population, and you’ll know if you’re in it.

6. Umbrella insurance — later

An umbrella policy adds liability coverage on top of your auto and home/renters policies. Typical: $1M of additional coverage for $200–$400/year.

You don’t need this in your first job. You might need it once you:

• Own real estate
• Have a teen driver in the household
• Have a dog with a known bite history (insurers actually price this)
• Have meaningful net worth that could be a target in a lawsuit
• Run a side business with public exposure

Worth a look once your assets cross ~$300K, or when you have kids of driving age.

What to skip entirely

• Extended warranties. The expected payout is always less than the cost — that’s why they’re profitable. Use a credit card that adds free warranty extensions, then self-insure.
• Identity theft insurance as a paid product. Most of what it offers is free elsewhere — credit freezes (free), credit monitoring (often free through your bank or card), fraud reimbursement (already required by federal law on credit cards).
• Mortgage life insurance — overpriced term life with a single beneficiary (the lender). Get regular term life instead.
• Cancer-only / specific-disease policies — duplicates what good health insurance already covers.
• Air travel insurance at the gate.

Common mistakes

• State-minimum auto liability. Cheap monthly, financially catastrophic if you cause a serious accident. Bump to 100/300/100 at minimum.
• No renters insurance. $15/month policy, $30K of stuff at risk. The math is unambiguous.
• No disability coverage. The single biggest gap in most young adults’ insurance, and the most likely to actually fire.
• Whole life sold as “investment.” It is not an investment. Term + index funds beats it almost every time.
• Buying life insurance for kids. Kids don’t have income to replace. Skip.
• Carrying low deductibles to feel safer. Once you have an emergency fund, take the higher deductible and bank the savings.

A simple checklist

If you can answer yes to each of these, you’re in good shape:

• I have health insurance (HDHP or PPO, run the math each year).
• I have auto liability at 100/300/100 or higher (if I drive).
• I have renters insurance (if I rent).
• I have long-term disability coverage (through employer or individual).
• I have term life insurance if and only if someone depends on my income.
• I do not have whole/universal/variable life insurance.
• I am not paying for extended warranties, identity theft insurance, or other low-value add-ons.

Key takeaways

• Insurance protects against things you can’t recover from. Everything else is a budget item.
• For young adults: health and auto are mandatory; renters and disability are highly recommended; term life only if dependents.
• The HDHP/HSA combo wins more often than people realize.
• Disability insurance is the most-overlooked policy and the most likely to actually pay out.
• Avoid whole/universal/variable life unless you’re in a narrow estate-planning case.
• Umbrella later, once net worth and exposure grow.
