Term vs. Whole Life:
the commission tells the story

The chapter that was already written

$230 Billion a Year Is the Price of Inattention: the fees worth moving accounts over told this story from the seller's side (When Whole Life Is Sold, Not Bought): the gap in commission that means whole life gets sold while term gets bought, how many policies lapse, and the arithmetic of buying term and investing the difference. This chapter tells it from your side, because a track about defending yourself would be incomplete without the product that gets mis-sold most — and because here the question is how you decide, not why they're selling.

Working out what you need

Life insurance exists for one situation: people depend on your income, and your dying would turn their grief into financial ruin.

That tells you how much you need. Enough to carry those people until they can support themselves — the income replaced for as many years as it's needed, debts cleared, education paid for. Common rules of thumb use a multiple of income, and getting the number right is a job for a professional.

It also tells you how long you need it for, which is not forever. Children grow up. Mortgages get paid off. A partner's career matures. So the need is finite, usually somewhere between a few hundred thousand and a couple of million, and it lasts a defined number of years.

That shape is exactly what term insurance prices cheaply. Most term policies expire without paying out, which is why they cost so little — and, per Insure Catastrophes, Not Inconveniences, losing money on average is fine here. What you're buying is the ceiling on how bad things get.

Sometimes the answer is none at all. No dependants and no income anyone relies on means no need for life insurance, whatever the enrollment form at work implies.

And the need shrinks over time. A 30-year policy bought at 35 is protecting something that gets smaller every year as your savings grow (the arc of Chapter 6). Plenty of households can cover the risk out of their own wealth well before the policy ends. That's the system working as intended.

Running the decision cleanly

Work out what you need: how many years of dependency, times the income gap, checked by a professional. Then price term cover for that amount and that length, comparing several quotes — this is a commodity, and Shopping Auto Insurers Saved a Median of $461 a Year: what else is negotiable explains why you shop it.

If someone pitches you a permanent policy, use everything in When Whole Life Is Sold, Not Bought: compare it against buying term and investing the difference, look at how many of these policies lapse, and ask what the commission is out loud.

There are narrow, real uses for permanent insurance — certain estate arrangements, provision for a child with special needs. Those arrive through an estate lawyer, not through an illustration at your kitchen table. If the pitch came with a salesperson attached, App Is Free? how it makes money from you instead already told you what that means.

The takeaway

Life insurance replaces your income for the people who depend on it, for as long as they depend on it. That's a finite need, and term cover fits it exactly and cheaply. Work out the amount honestly, shop it like the commodity it is, and let it expire unused as your own savings take over the job. When the permanent-policy illustration appears, remember that the whole story is in the fact that it needed a salesperson.
