Module 4

Managing risk

Module 3 was about the risk you take on purpose, because it pays. This one is about the risk you would pay to be rid of. They are opposite decisions and people routinely get them the wrong way round: cautious with the money that should be growing, and uninsured against the thing that would actually ruin them.

By the end
You can say what insurance is buying, work out whether a deductible is worth the lower premium, and name the part of your pay you never see.

Guess before you read on

Health cover for a family of four, for one year

Through an ordinary job in the United States, counting everything paid for it by everybody. Not the bit taken off a payslip: the whole price of the cover. Write down a number before you scroll.

The part of your pay you never see

Employer health cover Just you A family

Source: . Note: these are averages across employers who offer cover. They say nothing about any particular job, and a job with no cover at all is not in this table.

The row that should stop you is the last one. Somebody is paying the difference between what the cover costs and what comes off the payslip, and that somebody is the employer, out of money they are spending to employ you. It is part of what you are paid. It is simply not part of what you are paid in money, so it never appears on a payslip and almost nobody counts it.

This is why two jobs paying the same are not paying the same. A job with family cover and a job without, at identical salaries, differ by roughly the employer's share above. Module 5 compares jobs by their published wage, which is the number everybody quotes and not the number that decides how much you keep.

What insurance is actually buying

Insurance is a bad deal on average, and that is not a criticism of it. If the company took in less than it paid out it would not exist. Over enough people and enough years, the premiums have to exceed the claims, so the average buyer pays more than they get back.

You buy it anyway, and the reason is the central idea of this module. You are exchanging a small loss you can survive for the removal of a large one you cannot. The average is not what you are managing. The worst case is.

Which tells you exactly when insurance is worth buying and when it is not. Insure the losses that would end you: the house, the liability, the years of income you would lose if you could not work. Do not insure a phone screen. You can absorb a phone screen, and paying somebody a margin to absorb it for you is buying a bad deal for no reason.

The test is not "how likely is this". It is "what happens to me if it does". A one-in-a-thousand event that takes everything is worth insuring. A one-in-three event that costs $200 is not.

The deductible trade, in numbers

A higher deductible means a lower premium: you are agreeing to absorb more of a claim yourself, so the company charges less to carry the rest. Whether that is a good trade depends on two things you can work out and one you cannot.

Over ten years, the high deductible

And the thing you cannot work out. Whether you would have the deductible in the bank on the day you needed it. A cheaper premium you can afford every month, with a deductible you cannot afford once, is not a saving. It is the large loss you were trying to insure against, moved.

The cover you buy from yourself

An emergency fund is insurance you sell to yourself. You hold cash you could have invested, and what you get for it is that a broken car does not become a credit card balance at 22% that outlives the car.

Module 3 said cash loses to inflation every year and it was right. This is the exception, and it is the same reasoning: you are paying a known small cost, the growth you gave up, to remove a large one. The premium is real. So is what it buys.

The fund costs you

What this figure is. The growth given up by holding the money as cash instead of investing it, at the same 5% after inflation the rest of this course uses, compounded monthly. It is a real cost and it is the price of the cover. Whether it is worth paying is a judgment about your own life, not an arithmetic result, and this page will not pretend otherwise.

What this module leaves out

More than any other page in this course, and it is worth being blunt about which parts.

  • How to choose a policy. Networks, copays, coinsurance, exclusions, riders, and the difference between two policies with the same premium. That is most of the actual skill and none of it is here.
  • What cover costs where you live. Every figure on this page is a national average. Insurance is priced locally and by person, and the number you are quoted may not resemble any of these.
  • Life and disability cover. Named in the reasoning above and not priced anywhere in this course. Disability is the one most people underweight most badly, because it is likelier than dying young and the loss is similar.
  • Anything about health systems outside the United States. The employer figures above are a fact about one country's arrangements, not about how cover works.
The reasoning survives the gaps. You do not need a quote to answer the question this module is about: which losses would end me, and which can I absorb. That question is the same in every country and at every price, and it is the one worth taking out of here.

Six problems

Estimate first where a number is asked for. Anything within 25% counts, for the same reason it did in Module 1.

1. The loss that would end you

Name one loss that would end you, and say whether you are covered for it. Not the one that would annoy you or set you back a year: the one you could not absorb. Most people can name it in a sentence and have never checked the second half.

2. Something insured that could be carried

Name one thing you or your family insures that could be absorbed instead. What would carrying it yourself cost, and what would it save? This is the same trade as the deductible above, made on a whole policy rather than on one number in it.

Next: Module 5, education and earnings

You now have both halves of risk: the movement you take on for a return, and the loss you pay to be rid of. Module 5 is about where the money to do either comes from, and it is the one part of this course built on somebody else's measured figures.
