Life insurance basics

Life insurance is not for you. That is the part that makes it hard to think about clearly.

Every other policy you own protects something you can see: the car, the house, your own liability. Life insurance protects people, from a situation you will not be present for. There is no version where you experience the benefit.

Which means the question is not “do I want this.” It is: if my income stopped permanently tomorrow, who would be in trouble, and how much trouble?

What all policies have in common

The NAIC puts the shared structure simply: policies “are designed to pay money to the ‘named beneficiaries’ when you die. The beneficiaries can be one or more individuals or even an organization.”

Three things follow that are worth stating explicitly.

The beneficiary designation controls. It is on the policy, not in your will, and it generally governs. A designation that has not been reviewed since a marriage, a divorce or a birth is the single most common serious mistake in life insurance — and it is free to fix.

You can name more than one. You may name multiple beneficiaries and specify what percentage each receives.

A beneficiary need not be a person. It can be an organisation, or a trust.

The two families of policy

Term. “Term life insurance is a policy that is purchased for a period of time (a term).” It provides “lower-cost coverage for a specific period,” and most term policies build no cash value.

If you die during the term, it pays. If the term ends and you are alive, it stops. That is the whole product, and its simplicity is why it is cheap.

Permanent, or cash value. “A cash value life insurance policy is different because you can keep it for as long as you need it. These policies also have savings or investment features, which make it possible for policy owners to get money from the policy while they’re still alive.”

Two things are happening at once in a permanent policy — a death benefit and an accumulating account — and because of that savings element, premiums are generally higher than for term coverage.

The distinction that confuses everyone

Inside a permanent policy there are two numbers, and people routinely assume they add together.

They do not. The NAIC is unambiguous: “When you die, the insurance company will pay the death benefit. No matter how much cash value you may have had in the policy the moment before you died, your beneficiaries can collect no more than the stated death benefit.”

The face amount is what gets paid at death. The cash value is money available to you while alive. It is not an additional payout waiting for your beneficiaries, and understanding that before you buy prevents a significant misunderstanding later.

The NAIC also notes that cash value builds differently across products — “in some cash value policies, the values are low in the early years but build later,” while in others it accumulates more gradually.

How much, and for how long

There is no formula that produces a correct answer, because the inputs are personal.

The NAIC frames the categories worth thinking through: income replacement, support for dependants, final expenses, debt repayment, education funding, and estate taxes. It offers a multiple of current income as a starting point while noting that personal circumstances vary significantly.

Treat any multiple as a conversation starter rather than a conclusion. Two households with identical incomes can have entirely different answers depending on whether there is a mortgage, how many dependants there are, how old they are, whether a surviving partner earns, and what other resources exist.

The duration question is often more useful than the amount question. For how many more years would somebody be in difficulty if your income stopped? That number tends to point clearly at whether the need is time-limited or indefinite — which is most of the term-versus-permanent decision.

Who does not need it

Worth saying plainly, because the industry rarely does.

If nobody depends on your income, and your death would not leave debts that fall to somebody else, the case for life insurance is weak. A single person with no dependants and no co-signed obligations may genuinely not need any.

Two caveats. Final expenses still fall on someone. And insurability is not permanent — coverage generally costs less and is easier to obtain when you are younger and healthier, so a decision to wait is a decision to accept that risk.

What to do

Answer the two structural questions before you speak to anybody: who would be in financial difficulty if your income stopped, and for how many years.

Then check your existing beneficiary designations — on any policy you already have, and on employer coverage. This costs nothing and is the most commonly out-of-date thing in the whole product.

When you do get a quote, ask for term and permanent options side by side so you can see what the difference actually costs, rather than being shown one.
