Topic: Insurance · Type: Evergreen · Reading time: ~8 min

Most people's insurance portfolio was assembled by accident. You took whatever your employer offered at onboarding. You selected "comprehensive" on the car insurance form because it sounded safest. You have no idea whether the numbers you chose mean anything. If this describes you, you are not alone — and it's not your fault. Insurance is deliberately confusing, sold through jargon, and never once explained in any structured way during education.

This article is the clear framework nobody gave you: what insurance actually is, how to decide what you need, which types matter most, and which you can skip without losing sleep.

The one principle that makes every insurance decision easier

Insurance is not a savings product. It is not an investment. It is a tool for transferring financial risk you cannot afford to absorb yourself.

That single sentence is the mental model. Every insurance decision — whether to buy a policy, how much coverage to get, whether to renew — runs through it. The question is never "should I insure this?" in the abstract. The question is: if the worst-case scenario happened, could I financially survive it without coverage?

If the answer is yes, you can self-insure (skip the premium). If the answer is no, you need coverage. This is why insuring a £200 phone isn't rational, but insuring your ability to earn an income absolutely is.

Apply this to every policy you hold or are considering. You'll make better decisions immediately.

What insurance do you actually need: the core four

1. Health insurance — non-negotiable everywhere

The financial case for health insurance requires almost no argument. A single hospitalisation without coverage can produce bills of tens of thousands of dollars, pounds, or euros depending on your country. Even in countries with universal public healthcare, supplemental private cover can meaningfully reduce waiting times and out-of-pocket costs for serious conditions.

In the US specifically, the stakes are extreme. As of 2024, roughly 27.7 million Americans — about 10% of the non-elderly population — were uninsured, according to federal health data. Many more are underinsured: the Commonwealth Fund defines underinsurance as situations where out-of-pocket medical costs, excluding premiums, equal 10% or more of household income. Being underinsured is not materially different from being uninsured when a serious illness hits.

The practical priority if you're in the US: check whether your employer offers a plan first. If not, use your country's marketplace or equivalent. And look carefully at your deductible — the amount you pay before insurance kicks in. A plan with a £/$/€5,000 deductible on a modest income is closer to no insurance than it looks on paper.

2. Disability insurance — the one most people skip and shouldn't

This is probably the most underinsured category in personal finance, and the asymmetry is remarkable.

About one in four of today's 20-year-olds will become disabled before reaching retirement age, according to Social Security Administration data. Most disabilities are not dramatic — they're back injuries, chronic pain, cancer treatment, or mental health conditions that simply prevent someone from working for months or years. Yet most people have either no disability coverage, or only the thin employer-provided group plan which typically replaces around 60% of salary and expires after a few years.

Income protection insurance (the UK/Australian/European term) or long-term disability insurance (the US term) typically costs 1–3% of your annual income and replaces between 60–80% of your gross earnings if you're unable to work. For someone earning £40,000, that's £400–£1,200 per year — roughly the cost of a weekend away — to protect your most valuable financial asset.

That asset, by the way, is your ability to earn. A 35-year-old with 30 working years ahead of them, earning £45,000 per year, has a human capital value of over £1 million before accounting for pay increases. You'd insure a £300,000 house. This is worth more.

For a deeper look at what these policies actually cover and how to compare them, disability insurance: the coverage most people forget to buy walks through the specifics.

3. Renters insurance — the cheapest policy most renters don't have

If you rent your home, your landlord's insurance does not cover your belongings. This is one of the most widespread and costly misconceptions in personal finance. Landlord insurance covers the building structure and the owner's liability. When someone breaks into your flat and takes your laptop, or a burst pipe destroys your furniture, you are bearing that cost yourself — unless you have renters insurance.

As of late 2025, roughly 45% of U.S. renters have no renters insurance, according to MoneyGeek data. The average annual premium is around $174 — roughly $14–18 per month. Typical claims for theft, water damage, and fire losses run into the thousands, sometimes tens of thousands. The maths are almost offensively clear.

Renters insurance typically covers three things: your personal belongings (theft, fire, water damage), liability if someone is injured in your home, and temporary accommodation costs if your rental becomes uninhabitable. All three represent real financial risks that can materialise without warning.

Worth knowing: In 2024, following Hurricane Helene, only 2.6% of renter households registering for FEMA disaster assistance reported having any property insurance at all. The financial impact on uninsured renters compared to insured ones in the same events was not close.

4. Term life insurance — only if others depend on your income

Life insurance is misunderstood in both directions. Some people think everyone needs it. Some think it's a scam. The clear answer: you need life insurance if and only if other people depend on your income to maintain their financial security.

If you have a partner, children, or dependants who would face genuine financial hardship if your income disappeared, term life insurance is one of the best-value financial products available. A healthy 30-year-old woman can typically purchase £500,000 of 20-year term cover for under £20 per month. The payout, if it's ever needed, can replace a decade or more of income and clear a mortgage.

If you have no dependants, you probably don't need life insurance right now. The pressure you may feel to buy it — from well-meaning relatives, financial advisers with commission structures, or general anxiety about mortality — is not a financial need.

The nuances of term vs. whole life, how much cover you actually need, and when whole life makes sense are covered in do you really need life insurance? The honest answer.

What you can usually skip (or approach with scepticism)

Appliance and gadget insurance: Cover offered on electronics, white goods, or mobile phones through retailers is almost always poor value. The premium is priced to be profitable for the seller. If you have an emergency fund that covers a £300–500 replacement, self-insure.

Whole life or investment-linked policies sold at the door: If someone is offering you life insurance that also builds a "cash value" or "investment component," ask very pointed questions about the charges, the guaranteed return, and the surrender penalties. These products can make sense in specific estate planning situations; they almost never make sense for most people as their primary insurance strategy.

Extended warranties on cars: If you're buying a new or certified pre-owned car, manufacturer warranties and statutory consumer protections in most countries already cover significant defects for several years. Extended warranty add-ons sold by dealerships are priced to be profitable for the dealership.

This isn't a rule against all supplemental insurance — it's a prompt to run the mental model. Could you cover the worst case yourself? What are you actually buying?

The one habit that protects your coverage long-term

Review your insurance once a year — not obsessively, just systematically. Life circumstances change in ways that affect what you need: a new partner or child changes your life insurance requirement. A pay rise changes how much disability cover you need. Moving to a higher-crime area changes the renters or home insurance calculation.

Most people set up their insurance at a transition point (first job, first flat, first car) and then ignore it for years. The policy that was right at 24 is often wrong at 34.

For a structured annual audit of what to check and what to change, how to actually read your insurance policy and spot gaps has a practical walkthrough. And if you want to understand the most common — and expensive — mistakes people make with their coverage, the 5 most common insurance mistakes that could ruin you is worth reading alongside this one.

Where to start if you're not sure where you stand

Pick the most consequential gap first. If you rent and have no renters insurance, that takes ten minutes and costs the equivalent of a cinema ticket per month — sort it today. If you work and have no disability or income protection coverage, check whether your employer offers anything, then look at what a personal policy costs for your age and occupation.

The goal isn't a perfect insurance portfolio assembled overnight. It's to ensure that no single realistic bad event — illness, accident, theft, death — could financially derail you or the people who depend on you. Everything else is secondary.
