How Much Life Insurance Do You Actually Need?

You have probably seen the rule about buying ten times your income. It is popular because it is easy to say, and it is wrong often enough to be worth ignoring. It produces far too little for a young family with a large mortgage and far too much for someone whose house is paid off and whose children have left.

A better question is simpler and harder: if your income stopped permanently tomorrow, what would your household actually have to cover, and for how long? Answer that and the number falls out of it.

What to add up

• What you oweThe remaining mortgage balance, car loans, credit cards, and any private debt someone else would be left holding. Include anything co-signed.
• Income your household would loseNot your gross salary. The portion of it your household actually spends, multiplied by the number of years they would need it. For most families that is the years until the youngest child is independent, or until a surviving partner reaches retirement savings they can draw on.
• Costs your death would createChildcare that a stay-at-home parent currently provides for free is the one people forget, and it is expensive. Add funeral and final expenses, which arrive within days rather than months.
• Goals you intend to fundEducation is the common one. Use the figure you actually expect to contribute, not a full sticker price you were never going to pay.

What to subtract

Existing coverage counts, with one caveat worth taking seriously. Group life through an employer usually ends when the job does, and it is rarely portable on good terms. Counting on it means assuming you will still hold that job on the day it is needed. Subtract it, but do not build the whole plan on it.

Savings count too, but only the portion your family would genuinely spend on these costs. An emergency fund is not life insurance and draining it is not a plan.

How long does the coverage need to last?

The second question matters as much as the first, and it usually points at term length. Look at when the obligations you just added up actually end. If the mortgage has nineteen years left and your youngest is six, a twenty-year term covers the period where a gap would be catastrophic, and a thirty-year term is paying for years in which nobody depends on your income.

That is not an argument for buying the shortest term you can justify. Renewing later means applying again at an older age with whatever health you have by then. It is an argument for matching the term to the obligation and, where affordable, giving yourself a few years of margin.

If the need never ends — a lifelong dependant, an estate that will owe something, a legacy you intend to leave — that is where permanent coverage earns the higher premium rather than the other way round.

Two mistakes worth avoiding

Insuring only the earner. If one partner stays home, the household would still have to replace what they do, and the cost of doing that commercially is not small. Coverage on a non-earning partner is routinely underbought.

Buying less than you need because of the premium. This is the common one, and it is usually solved by changing the policy type rather than the benefit. Term coverage is dramatically cheaper per dollar than permanent, so a household that cannot afford the permanent policy it was quoted can often afford the full benefit it actually needs in term form. Get the amount right first, then work out the structure.
