Life insurance splits into two families. Term insurance covers you for a fixed number of years and pays a death benefit if you die during that window. Permanent insurance, which includes whole life and the various universal life designs, covers you for life and accumulates a cash value alongside the death benefit. They are priced very differently because they are doing very different jobs.

What term actually is

You choose a face amount and a length, typically 10, 15, 20, or 30 years. The premium is level for that period. If you die during the term, your beneficiaries receive the face amount, income tax free in most circumstances. If you outlive the term, the policy ends and nothing is paid. That last sentence is what people dislike about term, and it is also exactly why it is inexpensive.

Term is priced against the odds of dying in a defined window, which for a healthy person in their thirties or forties is low. That is why a healthy 38 year old can often buy a large amount of 20 year coverage for something in the range of a modest monthly bill, while the same face amount as a permanent policy can cost many times more.

What permanent adds

Permanent policies do not expire as long as premiums are paid, and part of every premium builds a cash value inside the policy that grows tax deferred. You can borrow against it, and depending on policy type you may be able to withdraw from it. The death benefit is not tied to a window, so the policy will pay whenever death occurs.

Those features are real. They are also what you are paying the higher premium for, and they only make sense when you have a need that genuinely lasts a lifetime.

The question that settles it

Ask how long the money is needed. Most household life insurance need has an end date, and once you say it out loud the answer usually becomes obvious.

If your need has a horizon, buy term that reaches past the longest one and buy enough of it. A larger term policy that actually covers the mortgage beats a small permanent policy that does not, and this is the trade people get wrong most often. They buy $100,000 of permanent coverage when the family needs $700,000 for eighteen years.

When permanent earns its place

There are real cases where lifelong coverage is the point:

How to size the coverage

A workable method is to add up four things and subtract what you already have. Debts you would leave behind, including the mortgage. Income replacement, usually the annual income you provide times the number of years it is needed. Education costs, if you intend to fund them. Final expenses. Then subtract existing coverage and liquid savings. The remainder is roughly what you need to buy.

Do not skip employer group coverage in that subtraction, but do not lean on it either. Group life is usually one or two times salary and it ends when the job does, which is exactly the moment a family is least able to replace it.

Provisions worth reading

Convertibility. Many term policies allow conversion to a permanent policy without new medical underwriting, up to a stated age or number of years. If your health changes, that provision is enormously valuable. Check the deadline before you buy.

Renewal pricing. A term policy that renews annually after the level period does so at sharply increasing rates. It is a bridge, not a plan.

Contestability. For the first two years, an insurer can investigate and rescind for a material misstatement on the application. Answer the health and tobacco questions accurately. A policy that gets denied at claim time was never coverage at all.

The practical middle

Laddering solves most real situations. Buy a 30 year policy sized to the mortgage and a 20 year policy sized to the child-rearing years. The total coverage is highest when the family is most exposed and steps down as obligations retire, and the total premium is far lower than one large 30 year policy carried the whole way.
