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. Three lines is enough:

1. Annual premium delta. Subtract the HDHP’s yearly premium from the PPO’s. This is what the HDHP saves you up front, before any care.
2. Expected out-of-pocket. Roughly what you’ll actually pay under each plan in a typical year (a few visits, a script or two), plus a what-if for a bad year that hits the deductible.
3. HSA tax value. The pre-tax savings on whatever you’d route through the HSA — your federal marginal rate × your planned HSA contribution. The HDHP unlocks this; the PPO doesn’t.

The HDHP wins when the premium savings plus the HSA tax value clear the expected out-of-pocket gap. It wins more often for young adults than people realize — see the Guide to HSAs for the full picture, including why 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 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.

Between the two sits the elimination period — the waiting stretch between when you’re disabled and when LTD starts paying. On most group LTD policies it’s 90 days. STD covers that gap by design; if you only have LTD, the bridge is your emergency fund, full stop. Three months of zero income with no STD and no e-fund is the worst-case scenario this whole section is trying to prevent.

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% (the gap shrinks for very-low-earners in the 10%–12% brackets and widens for higher earners; the 22% marginal case is the typical young-adult example).

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 products bundle a death benefit with a cash-value or investment component. They’re sold aggressively — first-year commissions on whole and universal life often run 50%–100% of the first year’s premium straight to the agent (variable products are typically lower but still well above term).

The pitches you’ll hear, by product:

• Whole life (WL) — “Permanent protection plus guaranteed cash value. Be your own bank.” Cash value grows at a guaranteed rate (typically 2%–4%), often topped up with dividends from a mutual insurance company. You can borrow against the cash value without “interrupting compounding” (a strategy sometimes marketed as “infinite banking”). The mechanics: the loan pledges the policy as collateral and accrues 5–8% interest, and if the unpaid balance ever exceeds the cash value the policy lapses and the borrowed amount becomes taxable income. “Uninterrupted compounding” is marketing; the insurer charges you interest on your own money.

• Universal life (UL) — “Flexible premiums, flexible death benefit.” Pay more or less as your budget changes; cash value grows at the insurer’s current interest rate.

• Indexed universal life (IUL) — “Stock-market upside without the downside. Tax-free retirement income.” Cash value is indexed to the S&P 500 with a cap (you only get part of the year’s gain) and a floor (the index credit can’t go below zero, but the insurance and administrative fees keep eroding cash value in down years regardless, so “no losses” is misleading). Heavily marketed as a LIRP (life insurance retirement plan), pitched as a tax-free alternative to a 401(k). The hot pitch on TikTok and YouTube right now.

• Variable universal life (VUL) — “Direct market exposure inside a tax-advantaged wrapper.” Cash value is invested in mutual-fund- like subaccounts you choose.

Why ~95% of people should still skip them:

1. Cost. Same coverage as term life costs 5×–10×. Most early premiums go to fees and commissions, not your cash value.
2. Performance. Whole life: 2%–4% effective. IUL caps (currently ~8%–10%) can be cut later by the insurer, and participation rates are often less than 100% — so the marketed “S&P 500 upside” is usually 60%–80% of the index at best. VUL adds 1%–3% in policy fees on top of the funds’ own expense ratios.
3. Surrender penalties. Cancel in years 1–10 and you’ll typically get back less than you put in.
4. Complexity. 50+ page contracts with riders, carve-outs, and surrender schedules. Hard to compare across insurers and easy to mis-sell.

The honest use cases are narrow: very-high-net-worth estate planning (after maxing every other tax-advantaged account), or supplemental retirement income for someone who’s already saved aggressively elsewhere. If you’re not in one of those buckets, term life + index funds beats the bundled product nearly every time — which is exactly what the chart below shows.

The long-run gap is only half the story. The surrender schedule (point #3 above) means there is no clean way out for the first decade — what your statement shows and what you can take with you are not the same number.

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 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 pay out.
• Avoid whole/universal/variable life unless you’re in a narrow estate-planning case.
• Umbrella later, once net worth and exposure grow.
