Is Life Insurance Worth It? It Depends Entirely on One Question
Whether life insurance is worth buying comes down to financial dependants. Who genuinely needs it, who does not, how much, and why term beats whole life for most people.

Life insurance attracts more bad advice than any other product in personal finance, in both directions. The honest answer is narrower than the industry suggests and broader than the sceptics do.
The one question
Would somebody suffer financially if you died?
That is the test. If the answer is yes, life insurance is almost certainly worth it. If the answer is no, it usually is not, and the various arguments for buying it anyway deserve scrutiny.
People who need it: anyone with a partner who relies on their income; anyone with children; anyone supporting a dependent parent or relative; anyone with a mortgage or debt that a survivor would inherit or that is jointly held; anyone whose unpaid work would have to be paid for; anyone with a business partner or a business loan they have personally guaranteed.
People who generally do not: single adults with no dependants and no co-signed debt; retirees whose children are independent and whose partner is provided for; anyone whose estate would comfortably cover everything without it.
Everything else in this article follows from which side of that line you sit on.
What it is not
Two claims deserve dealing with directly.
Life insurance is not an investment. Term life insurance has no investment component at all; it is pure protection. Permanent policies contain a savings element, but the returns net of the insurance and administrative costs inside them compare poorly with ordinary investing for most people. Our guide to term versus whole life insurance works through the comparison.
Life insurance is not a substitute for savings. It answers a specific catastrophic risk. It does not build wealth, fund retirement, or replace an emergency fund.
The reliable framing is: buy protection for the risk, invest separately for the return. The two are separate products doing separate jobs, and combining them usually means paying more for both.
The case people miss most
A stay-at-home parent should frequently be insured, and this is the single most commonly overlooked situation.
The reasoning is straightforward. The unpaid work has a replacement cost: childcare, school runs, meals, household management, care of an elderly relative. If that person died, the surviving partner would have to buy those services, at market rates, while continuing to work.
Worked example: the replacement cost of unpaid work
A household with two children under school age.
| Service | Annual replacement cost |
|---|---|
| Full-time childcare, two children | $24,000 |
| After-school and holiday cover | $3,600 |
| Household cleaning and laundry | $4,800 |
| Meal preparation and shopping | $3,900 |
| Transport and appointments | $2,400 |
| Annual total | $38,700 |
Over the years until the children are independent, that is a six-figure exposure with no income attached to it. It is exactly what life insurance is for, and a term policy on that person costs very little.
How much
The honest answer is that it comes from a calculation rather than a rule of thumb, but a rule of thumb is a reasonable starting point.
Ten to twelve times annual income is the common heuristic, and it is a starting point rather than an answer.
The calculation that improves on it:
Income replacement, for the number of years dependants would actually need it. That is not necessarily to retirement; for many households it is until the youngest child is independent.
The mortgage and any other debt a survivor would carry.
Childcare and education costs, which are frequently the largest single component and are frequently omitted.
Final expenses, meaning funeral costs and estate administration.
Minus existing resources: savings, investments, any employer cover, and any surviving partner’s income.
The result is usually larger than people expect and smaller than a salesperson’s illustration.
Term, for most people
Term life insurance covers a fixed period, commonly 10, 20 or 30 years, and pays only if you die during it. It is cheap because most policies never pay.
Permanent life insurance covers your whole life and accumulates a cash value. It is substantially more expensive for the same death benefit.
For most households, the right answer is term, and the reasoning is about timing rather than product quality. The need is temporary. Dependants need protection during the years when they are dependent. By the time a term policy expires, the mortgage should be smaller, the children independent, and retirement savings accumulated. The exposure that justified the policy has gone.
Permanent cover has genuine uses: estate liquidity for a large or illiquid estate, a lifelong dependant such as a disabled child, business succession funding, and certain tax situations. Those are real and they are not the majority case.
The arguments for buying when you do not need it
Three are commonly made, and they deserve honest treatment rather than dismissal.
“Buy it young while it is cheap.” Partly true. Premiums are lower at younger ages and locking in a long term before health changes has real value. But paying for twenty years of cover nobody needed is not a saving, and the money would generally have done more elsewhere. The version of this argument that holds up is: if you will predictably have dependants soon, buying slightly early is reasonable.
“You might become uninsurable.” Genuinely true, and the strongest of the three. A diagnosis can close the door permanently, and this is the real argument for buying before you strictly need it if you have a family history or a foreseeable need.
“It is forced savings.” The weakest. Permanent policies are an expensive savings vehicle, surrender values in early years are poor, and the discipline argument is better served by an automatic transfer to an investment account.
When to review it
When a child is born, which is the largest single change in need.
When you buy a house or take on significant debt.
When you marry, separate or divorce, including reviewing the beneficiary designation, which is the most commonly neglected document in personal finance.
When your income changes materially.
When you change jobs, because employer cover usually ends with the job.
When the youngest child becomes independent, which is frequently the point at which the need starts falling rather than rising.
Every few years regardless, because both the need and the market move.
The short version
Life insurance is worth it if somebody would suffer financially when you die, and generally not if nobody would. That single question answers it for most people.
It is not an investment, and combining protection with saving usually means paying more for both. Buy term for the years dependants need protecting, and invest the difference separately.
The case most commonly missed is a stay-at-home parent, whose unpaid work has a replacement cost running into six figures over the years it would be needed.
And if you have a family history or a foreseeable need, buying before you strictly need it has one genuinely strong argument behind it: insurability is not guaranteed to still be there when you get round to it.

The beneficiary designation, which decides everything
The most neglected document in personal finance is the beneficiary designation on a life policy, and it overrides a will.
Name a beneficiary and keep it current. A policy with no named beneficiary pays into the estate, which delays the money considerably and can expose it to creditors and probate costs.
Name a contingent beneficiary, so the proceeds have somewhere to go if the primary beneficiary dies first or at the same time.
Review it after every life event. Marriage, separation, divorce, a birth, a death. An ex-partner named on a policy from a previous relationship will receive the money, and the will does not change that.
Think carefully before naming a minor child directly. Insurers cannot generally pay a minor, so the proceeds go into a court-supervised arrangement, which is slow and inflexible. A trust or a named adult custodian is usually the better structure and it is worth taking advice on.
Tell somebody the policy exists. A meaningful number of policies go unclaimed simply because the family did not know. Keep the details with the will and tell the executor.
Our guide to life insurance and taxes covers how proceeds are treated, and multiple life insurance policies covers layering cover for different needs.
What to do next
If you have dependants and no cover, get a term quote today. It is cheaper and faster than most people expect, and the underwriting is straightforward for anyone in reasonable health.
If you have employer cover only, treat it as a supplement. Work out the gap between one or two times salary and what a needs calculation produces, and cover the difference with a personal policy that does not end when the job does.
If you have permanent cover you are unsure about, do not cancel it impulsively. Surrender values in early years are poor and replacing cover at an older age with changed health can be impossible. Get the in-force illustration and take independent advice.
If nobody depends on you, the honest answer is that you probably do not need it, and a small final expenses policy is a separate and much cheaper question.
Getting the amount right without overbuying
Two failure modes are common and they pull in opposite directions.
Underbuying, usually by relying on employer cover of one or two times salary, which is well below what a household with children needs and ends when the job does.
Overbuying, usually by accepting a multiple-of-income figure from somebody paid on the size of the policy, without netting off existing resources or considering how long the need actually lasts.
The correction for both is the same: do the needs calculation, net off what already exists, and set the term to the length of the actual dependency rather than to a round number.
Worked example: a needs calculation
A household with two children aged four and seven, one earner on $78,000, mortgage of $210,000.
| Component | Amount |
|---|---|
| Income replacement, 14 years to youngest independence | $640,000 |
| Mortgage clearance | $210,000 |
| Childcare and after-school costs | $58,000 |
| Higher education contribution | $60,000 |
| Final expenses and estate administration | $18,000 |
| Gross need | $986,000 |
| Less existing savings and investments | $84,000 |
| Less employer cover, two times salary | $156,000 |
| Policy required | Around $750,000 |
A twenty-year term policy at that level, for a healthy applicant in their thirties, is one of the cheapest lines in a household budget relative to what it does. The same face value as a permanent policy would cost several times more.
Layering, which is the efficient structure
Rather than one large policy for thirty years, many households are better served by layering two or three terms of different lengths.
A larger, shorter policy covers the years with young children and a large mortgage. A smaller, longer policy covers the tail. Total cost is lower than a single policy sized for the peak need and held for the whole period, because you stop paying for cover as the need falls away.
Our guide to multiple life insurance policies works through how to structure that.
A note on scope
Nothing here is financial, tax or legal advice, and life insurance decisions depend heavily on individual circumstances, health, tax position and family structure. Figures here are illustrative rather than quotes.
Your state insurance department publishes consumer guidance on life insurance, and the NAIC publishes buyer guides for term and permanent products. A licensed adviser who is paid for advice rather than for product sales is the appropriate source for a personal recommendation. This site is independent and not affiliated with any insurer.
