The test is not whether something might happen. It is whether you could survive it financially if it did — which is why most people are over-insured on trivia and exposed on the rest.
What insurance is for
It is not for small, predictable costs. Those belong in a budget or an emergency fund.
Insurance is for the rare event you could not absorb — the fire, the hospital stay, the lawsuit, the death of an earner. The test for whether to insure something is not "might this happen?" but "could I survive it financially if it did?"
Get that backwards and you end up over-insured on trivia and exposed on the things that would actually ruin you.
Health insurance: learn the four words
American health coverage confuses people because four terms do different jobs.
- Premium — what you pay monthly whether or not you use it.
- Deductible — what you pay yourself before the plan starts contributing.
- Copay and coinsurance — your share after the deductible: a flat fee, or a percentage.
- Out-of-pocket maximum — the ceiling. Once you hit it, the plan covers 100% of covered in-network care for the rest of the year.
That last one is the number that matters most and the one nobody compares. A cheap premium with a very high out-of-pocket maximum is not cheap insurance — it is a larger bet that you stay healthy. Compare plans by asking what a genuinely bad year costs under each: premium times twelve, plus the out-of-pocket maximum.
Also check whether your doctors and hospital are in network. Out-of-network care is where the frightening bills live.
If your plan qualifies as a high-deductible health plan, you can open a Health Savings Account — the only account that is untaxed going in, growing and coming out. It does not make a bad plan good, but it materially changes the arithmetic of choosing one.
Auto: the part that is too low by default
State minimum liability limits are frequently far below the cost of a serious accident. If you injure someone and the bills exceed your coverage, the difference is yours — wages and assets included.
Raising liability limits is usually inexpensive, because severe claims are rare. Meanwhile, collision and comprehensive on an old low-value car can cost more over a few years than the car is worth — that is the coverage to drop, not liability.
Renters: absurdly cheap, routinely skipped
A renters policy typically costs a few dollars a month and covers your belongings, temporary housing if the building becomes uninhabitable, and — the part people miss — personal liability if someone is injured in your home or you cause damage to the building.
Your landlord's insurance covers the landlord's property. It does nothing for yours.
Disability: the one that is genuinely under-bought
You are considerably more likely to be unable to work for an extended period than to die during your working years, yet almost everyone insures the second and not the first.
Disability insurance replaces part of your income if illness or injury stops you working. Many employers offer short-term and long-term cover, often cheaply. Two details worth reading: whether the policy defines disability as being unable to do your occupation or any occupation — a large difference — and whether benefits are taxable, which depends on who paid the premiums.
Life: only if someone depends on you
If nobody relies on your income, you probably do not need it. If someone does — children, a partner who could not manage the mortgage alone, a co-signed debt — you do.
Term life covers a fixed number of years for a fixed premium and is inexpensive when bought young and healthy. Whole and universal life combine insurance with an investment component, cost several times more, and are sold far more often than they are needed. For the great majority of families the honest answer is a term policy long enough to cover the years of dependence, with the difference invested.
What to skip
Extended warranties on cheap electronics. Credit card payment protection. Rental car coverage you may already have through your own policy or card. Flight insurance. Any policy covering a loss you could pay for out of savings without it changing your life.
A yearly review that takes ten minutes
Check that coverage still matches your life — a new child, a mortgage, a move, a raise all change what is at stake. Check your deductibles are amounts you could actually produce tomorrow. And get comparison quotes, because loyalty is not usually rewarded in this market.
