Is Life Insurance Worth It? Only If Someone Depends on Your Income

It usually arrives as a checkbox. You start a new job, the benefits screen offers supplemental life cover at one, two or three times salary, and you click whatever the default was because the next screen is about dental. Years later someone asks whether you have life insurance and you honestly are not sure. Is life insurance worth it, or was that checkbox the right amount of thought to give it?

The answer depends on a single fact about your life. Life insurance does one job: it replaces money that someone else depends on. If nobody loses income when you die, it is mostly money spent on nothing. If someone does, it is one of the cheapest forms of protection you can buy, and most people who need it have far less than they should.

Everything else, including the long argument about term versus whole life, comes after that fact.

The One Question That Decides It

Picture tomorrow without you. Then ask who is worse off financially, and by how much.

If the honest answer is “nobody, beyond the cost of a funeral”, you are in the group for whom life insurance is rarely worth it. If the answer involves a partner who could not cover the mortgage alone, children who are years from earning, or a business partner who would suddenly own a company with your heirs, you have a real need, and it has a size you can calculate.

The numbers suggest a lot of people have not asked the question. The 2025 Insurance Barometer Study from LIMRA and Life Happens found that 51 percent of Americans aged 18 to 75 own life insurance, while 40 percent say they need it or need more of it. The same study found that adults aged 30 and under overestimate the cost of a basic term policy by 10 to 12 times. Perceived cost is the reason people give most often for not buying.

So the typical gap is a person who needs cover, assumes they cannot afford it, and never checks.

Is Life Insurance Worth It? Four People Who Need It

Parents of young children. This is the clearest case. A child has fifteen or twenty years before earning anything, and the parent’s income is what pays for them. It applies to a parent who stays at home too. The childcare, driving and household work they do has a replacement cost, and it is a large one.

A household that runs on one income, or needs both. If the mortgage was approved on two salaries, losing one of them is a financial event as well as a personal one. Cover sized to clear the mortgage, or to carry it for a number of years, removes the forced sale from the list of things a grieving partner has to face.

Anyone who shares debt. A co-signed loan, a joint mortgage, a private loan from family. Whoever is left on the paperwork inherits the repayment.

Business owners with partners or key people. This one is covered separately below, because it is the case most often missed by people who have thought carefully about the others.

Who Usually Does Not Need It

A single person with no dependants and no shared debt. A retired couple whose savings and pensions already cover the survivor’s life. Children, almost always, despite the policies marketed for them.

The logic is the same in every case. There is no income to replace, so the premium buys protection against a loss that nobody would suffer.

Retirement is where need most often disappears on its own. Once the mortgage is paid, the children are independent and there is enough capital for the survivor, the job life insurance was doing has been taken over by savings. That point is worth knowing in advance, and it connects to a bigger question most people never pin down: how much money is actually enough.

How Much Cover, Worked Out Properly

The rules of thumb, like ten times salary, are a rough start. The better method takes twenty minutes and a sheet of numbers.

Add up what would need paying: outstanding debts including the mortgage, the income your family would need for as many years as they would need it, and any large future costs you intend to fund, such as university. Then subtract what already exists: savings, investments, and any cover you already hold through work.

What is left is the gap. That is the size of the policy.

Two things usually surprise people when they do this. The first is how large the number is once children are involved. The second is how little the work policy covers against it. Group cover through an employer is often one or two times salary, and it usually ends, or has to be converted on less favourable terms, when you leave the job.

If you would rather someone check the arithmetic with you, use an adviser who is not paid on the policy they recommend. The difference between fee-only and fee-based advisers matters more here than almost anywhere else, because life insurance commissions can be large.

Term or Whole Life: What the Difference Buys

Term life covers you for a fixed period, typically ten to thirty years, and pays out only if you die within it. Whole life covers you for life and builds a cash value inside the policy.

The price difference is large. In sample rates published by NerdWallet in February 2026, $500,000 of cover for a healthy 40-year-old man cost $330 a year on a 20-year term policy and $5,524 a year as whole life, almost seventeen times as much.

For most people who need cover, the need is temporary. It lasts until the children are grown and the mortgage is paid. A term policy matched to that window does the whole job at a fraction of the cost, and the difference in premium can be invested separately, where it is visible and under your control.

Match the length of the term to the length of the need. If your youngest child is three and the mortgage has twenty-two years left, a policy that runs twenty to twenty-five years covers both. Going longer costs more for years in which nobody would need the money.

Timing matters as well. Premiums are set largely by age and health at the point you apply, so the same policy costs more every year you wait, and a diagnosis in the meantime can make it far more expensive or unavailable. The cheapest moment to buy cover is usually the moment the need begins: the mortgage, the pregnancy, the business partner. People who wait for a calmer year tend to find the calmer year never arrives and the price has moved.

Whole life has legitimate uses. A dependant who will need support for life, such as an adult child with a disability. An estate large enough that the heirs will need cash to settle it. People who have already filled every other tax-advantaged account available to them. Those are real situations, and in them the product makes sense.

The premise worth questioning is the one it is usually sold on: that insurance should double as your investment. Bundling the two makes each one harder to judge. Protection is best bought as protection.

If You Own a Business, the Question Doubles

An owner has two sets of people depending on them: the family and the business. Each has its own gap.

On the family side, the calculation above applies, with one complication. Owners often pay themselves irregularly, or leave money in the company, which makes “the income to replace” a fuzzy number. Settling how much to pay yourself as a fixed salary does more than steady your own finances. It gives your family a clear figure to protect.

On the business side there are two common arrangements. Key person cover pays the company if someone whose absence would cost it revenue dies, buying time to hire and steady clients. A buy-sell agreement between co-owners sets out what happens to a partner’s share, and is often funded with life insurance, so the surviving owner can buy the share at an agreed price rather than suddenly running the company alongside a widow or widower who never wanted to be in it.

Neither is exotic. Both are routinely skipped by small companies that would never skip insuring their equipment.

The Arrangement You Make on an Ordinary Evening

So, is life insurance worth it? For a single person with no dependants, usually not. For a parent, a partner on a shared mortgage, or a business owner with a co-founder, it is close to non-negotiable, and a term policy usually does the job for much less than people expect.

The hard part is not the product. It is sitting down on an ordinary evening, when nothing is wrong, and doing the arithmetic for a day you would rather not picture. The same quiet planning that makes a real day off possible makes this possible too. You set things up in advance so that the people around you are not left holding the problem.

Most of the protection people need is cheap. What is expensive is never having checked.
