Insurance exists to transfer certain financial risks from individuals to larger risk pools. Understanding the basic purpose of insurance — what it can do and what it cannot — is a practical part of any financial resilience strategy.

“Insurance is one of those things that feels like a waste of money right up until you need it. Then it becomes one of the best decisions you ever made.”
I want to be clear about what insurance is and what it isn't. It's not a magic shield that keeps bad things from happening. It's not a guarantee that you won't face any out-of-pocket costs. And it's definitely not something you buy once and never think about again. What it is, is a way to make sure that a serious financial hit doesn't turn into a financial catastrophe. A house fire, a major medical event, a serious auto accident — these can cost more than most families earn in years. Insurance is what stands between that kind of event and a financial outcome you can't recover from. The key things I'd want anyone to take away from this lesson: understand what your policies actually cover, not just that they exist. Know what your deductibles are. Have emergency savings to handle the gaps. And review your coverage when your life changes significantly — because what was right five years ago may not be right today. Insurance is one part of the picture. A solid emergency fund, good benefit coverage through your employer and union, and some basic planning — those are the other parts. None of them replaces the others. They work together.
Insurance exists because some financial risks are too large for most individuals to absorb on their own.
A car accident that injures another person can produce liability costs of tens or hundreds of thousands of dollars. A house fire can cost more than most families earn in a decade. A serious illness can generate medical bills that exceed anything most workers could save in a lifetime. These are not exotic events — they happen to ordinary people in ordinary circumstances.
The core idea behind insurance is straightforward: many people face similar risks, but those risks typically strike a relatively small number of them at any given time. If a large group of people each contribute a modest amount — a premium — those contributions pool together into a fund large enough to cover the losses of the few who actually experience the adverse event.
For the individual, this transforms a rare but potentially catastrophic event into a predictable, manageable cost. Instead of facing an uninsurable loss alone, you face a known, regular premium. The event might still occur. The financial impact is dramatically different.
This is not a product pitch. Insurance companies are businesses with their own interests, and not every insurance product represents good value. But the core concept — pooling risk across many people to protect each one from catastrophic individual loss — is genuinely useful and is part of how financial resilience gets built.
Understanding what insurance actually does helps clarify what to expect from it — and what not to expect.
Insurance can reduce the financial impact of covered losses significantly. When you have appropriate coverage and a covered event occurs, the insurer pays some or most of the cost instead of you paying all of it. That shift can mean the difference between a temporary setback and a long-term financial crisis.
Insurance cannot prevent losses from occurring. Having health insurance does not prevent illness. Having home insurance does not prevent fire or theft. Having auto insurance does not prevent accidents. Insurance addresses the financial consequences of events, not the events themselves.
Insurance cannot cover everything. Every policy has exclusions, limits, deductibles, and conditions. A health insurance plan with a high deductible still leaves the policyholder absorbing thousands of dollars before coverage kicks in. Homeowners insurance typically excludes flood damage unless a separate flood policy exists. Understanding what a policy actually covers — not just assuming it covers everything — matters.
Insurance is not free, and the cost has to be weighed against the risk. For very small risks — a minor appliance replacement, a small repair — the cost of insurance may exceed the expected cost of the event itself. Insurance makes the most sense for large, infrequent events that would cause serious financial hardship without coverage.
And insurance is one layer, not the entire answer. Even with good coverage, most insurance policies leave gaps — deductibles, waiting periods, exclusions, limits. Emergency savings, benefit coverage, and planning fill those gaps. Insurance and other resilience layers work together.
Most households need to think about several categories of insurance at various points in their financial lives.
Health insurance covers medical expenses — doctor visits, hospital stays, surgeries, medications. Without it, even ordinary health needs can generate costs that are difficult to manage. With it, the same events produce costs that are significantly more manageable. Most working families access health insurance through an employer, a spouse's employer, a union benefit fund, or through a government marketplace.
Auto insurance is legally required in most states and serves two functions: it pays for damage to your vehicle in certain situations, and it pays for liability if you cause damage or injury to others. The liability function is often the more financially critical one — a serious accident can produce costs far exceeding the value of the vehicles involved.
Homeowners or renters insurance covers losses related to your home or belongings. Homeowners insurance typically covers the structure and contents against fire, theft, and certain other events. Renters insurance covers personal belongings for tenants who do not own their home. It is relatively inexpensive for the coverage it provides.
Life insurance replaces income when an income earner dies. It is most relevant for households where one person's death would create financial hardship for dependents who remain. The basic purpose is to ensure that dependents have financial support to transition to a new financial situation.
Disability insurance replaces a portion of income when illness or injury prevents work — which was covered in detail in FR-06. It is worth noting here because disability insurance is, in a sense, insurance for your ability to earn income, which is often the most valuable financial asset a working person has.
Liability coverage — sometimes available as an umbrella policy — extends protection beyond the limits of auto and homeowners policies for serious liability claims. For households with assets worth protecting, this additional layer is worth considering.
Insurance belongs in a financial resilience strategy, but it is not the only layer — and treating it as a substitute for other preparation creates real gaps.
Most insurance policies have deductibles — amounts you pay before coverage begins. A health plan with a $3,000 deductible still leaves you responsible for the first $3,000 of covered expenses each year. Disability insurance typically has a waiting period of seven to fourteen days — or longer — during which no benefits are paid. Homeowners claims below the deductible amount are handled entirely out of pocket. Emergency savings bridge these gaps.
Insurance premiums are an ongoing cost, and that cost has to fit within a realistic household budget. Over-insuring — paying for coverage whose cost exceeds a realistic assessment of the risk — wastes money that could be building emergency savings. Under-insuring — having no coverage or clearly inadequate coverage for serious risks — leaves households exposed to losses they cannot absorb.
The right balance looks different for every household depending on income, assets, dependents, health, occupation, and other factors. The goal is not maximum insurance coverage — it is appropriate coverage for the risks you actually face, combined with other resilience layers that handle what insurance does not.
A worker with good disability coverage through their benefit fund, a reasonable health plan, adequate auto liability coverage, and a funded emergency savings account is well-positioned to handle most of what ordinary financial life produces — not because any one of those things is perfect, but because the combination of layers covers a wide range of what can go wrong.
Insurance exists because some financial risks produce losses that individuals cannot absorb alone. By pooling risk across a large group of people, insurance transforms potential catastrophic costs into predictable, manageable premiums.
Insurance cannot prevent losses from occurring — it changes who bears the financial cost when they do. It works best for large, infrequent events that would create serious financial hardship without coverage. For smaller, more predictable expenses, emergency savings are typically more cost-effective.
Insurance is one layer in a financial resilience strategy — not the entire strategy. Deductibles, waiting periods, exclusions, and coverage limits mean that insurance gaps are normal and expected. Emergency savings, benefit coverage, and planning fill those gaps. The layers work together.
Scenario: Diana and her husband own a modest home they purchased six years ago. They maintain a homeowners insurance policy — they have never thought much about it, paid the premium every year, and kept the policy from when they first bought the house. On a Thursday evening, a grease fire in the kitchen spreads before they can contain it. The kitchen is extensively damaged, and smoke damage affects a significant portion of the house. The family cannot stay in the home while repairs are underway. They have a $1,500 deductible on their homeowners policy.
Outcome: The insurance company pays for the structural repairs to the kitchen and addresses the smoke damage to the rest of the house. The covered repair costs total approximately $38,000 — far more than the family could have covered on their own. Their homeowners policy also includes additional living expense coverage, which reimburses reasonable hotel and meal costs while the repairs are completed. The family pays the $1,500 deductible out of their emergency savings. The repairs take six weeks. The out-of-pocket total — deductible plus a few incidentals not fully covered — comes to approximately $2,200. The insurance did not prevent the fire. It did not cover everything. But it transformed what could have been a financially devastating event — tens of thousands of dollars in repair costs and extended displacement — into a $2,200 out-of-pocket expense and six weeks of inconvenience. After the experience, Diana reviews her policy carefully for the first time. She discovers that her personal property coverage limit had not been updated since the original purchase and is lower than the current replacement value of their belongings. She requests an update.
Lesson learned: Insurance worked in this situation because it was appropriate coverage for the type of event that occurred. It did not eliminate the problem — the family still dealt with six weeks of disruption and a $2,200 out-of-pocket cost. But it reduced a potentially ruinous financial hit to something manageable. That is what insurance is for — and why reviewing your coverage periodically ensures that it still does what you need it to do.
Assuming that having insurance means you are fully covered for any loss.
Why this happens: People naturally assume that once they have insurance, they are protected. But every policy has exclusions, deductibles, and limits. A health plan with a $5,000 deductible still leaves the policyholder responsible for the first $5,000. Flood damage is commonly excluded from standard homeowners policies. Disability coverage often has waiting periods before benefits begin. Not knowing what a policy actually covers can lead to unpleasant surprises during a claim.
Better approach: Read the key sections of your insurance policies — particularly the exclusions, deductibles, and coverage limits. Know what you are responsible for before coverage kicks in, and maintain emergency savings to cover those gaps.
Treating insurance as a substitute for emergency savings.
Why this happens: Insurance handles large, covered losses. Emergency savings handle deductibles, waiting periods, exclusions, and smaller expenses that are not worth filing a claim for. A worker with good insurance coverage but no emergency savings still faces cash-flow problems during a deductible period, a disability waiting period, or any covered but out-of-pocket portion of a loss. The two serve different functions and work best together.
Better approach: Build both — insurance coverage for large events and emergency savings for the gaps that insurance does not cover. The two layers work together, not as alternatives.
Never reviewing coverage to confirm it is still appropriate.
Why this happens: Life circumstances change — income increases, new dependents arrive, assets grow, coverage needs shift. Insurance purchased years ago may no longer reflect current needs. A life insurance policy purchased before children were born may have insufficient coverage now. Auto liability limits that felt adequate at a lower income level may be insufficient as household assets have grown. Coverage that is not periodically reviewed drifts out of alignment with actual needs.
Better approach: Review your key insurance policies periodically — at minimum, when a major life change occurs. Major life changes that typically warrant a coverage review include marriage, divorce, the birth of a child, a significant income change, purchasing a home, or inheriting assets.
