How Much Life Insurance Do You Need?

Life insurance exists to answer one question: if you died tomorrow, would the people who depend on your income be okay? If no one relies on your paycheck, you may not need it at all. If people do, this guide shows how much to buy and which kind.

Who actually needs life insurance

You need it if someone would suffer financially without your income — a spouse, children, or anyone who shares your debts. Single people with no dependents and no co-signed debt usually don't. The point isn't to insure a life; it's to replace the money that life provides.

Two ways to size it, and why they disagree

The quick method is a multiple of income, usually 10 to 12 times. On a $75,000 salary that is $750,000 to $900,000, and it has the single merit of taking ten seconds.

The needs-based method adds up what the money would actually have to do. For a household with $25,000 of consumer debt, a $280,000 mortgage, children who would depend on the income for another 18 years, and $100,000 of anticipated education costs, that comes to about $1,755,000 — roughly twice what the rule of thumb suggested.

The divergence is the point. Multiples of income are calibrated for a typical case and say nothing about your mortgage balance or how many years of dependency remain, which are the two variables that dominate the answer. A family with young children and a large mortgage is usually underinsured by the rule of thumb; an older household with the mortgage nearly repaid and children close to independence is often overinsured by it.

Subtract what already exists. Savings, investments, and any coverage provided at work all reduce the gap the policy has to fill — insurance covers the shortfall, not the whole obligation.

Term versus permanent

Term insurance covers a fixed period — commonly 10, 20 or 30 years — and pays only if you die within it. It is inexpensive because most policies never pay out, and it matches the shape of the actual risk: the years when children are young and the mortgage is large are exactly the years when your income is irreplaceable.

Permanent insurance, sold as whole life, universal life and variants, lasts for life and accumulates a cash value. It costs several times more for the same death benefit, and the returns credited to the cash value are generally modest once the policy's own costs are accounted for.

For most families with a temporary need, term insurance sized to the dependency period — investing the difference in premiums separately — is the straightforward answer, and it is what most fee-only advisers recommend. Permanent insurance has genuine uses: a dependant with special needs who will require support indefinitely, estate liquidity for an illiquid business or property, or a diagnosed condition making future coverage unobtainable. Those are specific situations, and none of them describes a typical family buying cover for the years the children are at home.

It is worth knowing that commissions on permanent policies are far larger than on term, so the product recommended to you is not always the product matched to you. That is a reason to ask how the person advising you is paid, not a reason to distrust the category.

The coverage you already have is rarely enough

Employer-provided life insurance is typically one or two times salary — $75,000 to $150,000 against a need closer to a million — and it usually ends when the job does. Treating it as your plan means your coverage disappears at the moment of a redundancy, which is not when you want to be applying for a new policy.

It is a useful supplement and a poor foundation. An individual policy you own is portable, priced on your health today, and unaffected by anything your employer decides later.

When to buy, and when to stop

Buy when someone first becomes financially dependent on you — a mortgage taken jointly, a marriage, a first child. Premiums are set by age and health at the time of application and stay level for the term, so buying earlier locks a lower price for the whole period. Waiting a few years costs more permanently, and a diagnosis in the interim can make coverage expensive or unavailable.

Review after anything that changes the obligation: another child, a larger mortgage, a significant change in income, a divorce. And recognise the endpoint. When the mortgage is repaid, the children are independent, and your savings could support your household on their own, the policy has done its job and the premiums are better used elsewhere. Insurance is scaffolding around the years you are still building; it is not meant to be permanent.

One practical note: if a term policy is approaching its end and the need has not, most policies allow conversion to permanent coverage without new medical underwriting, but only before a deadline set in the contract. That deadline is easy to miss and impossible to reopen.

Run your own number

Size the gap directly in the life insurance calculator, which works from debts, dependency years and existing assets rather than a multiple. Compare the two structures in the term vs whole life calculator, and establish what you have already built — which is the figure that reduces the coverage you need — in the net worth calculator. This is general information rather than advice on your circumstances; for a complex estate or a dependant with lifelong needs, the guidance of a fee-only adviser is worth its cost.
