Start with who, not how much
The amount of life insurance you need is not a personality trait. It is a number, and it falls out of one question: who would be financially hurt by your death, and by how much?
The Insurance Information Institute’s framework is the cleanest starting point. If you have no dependents and enough money to cover your final expenses, you may not need life insurance at all. If you have dependents, buy enough so that, combined with your other assets and income sources, the payout replaces the income you bring in for them, plus the cost of services they would have to pay someone else to do.
That second clause does real work. Income replacement is obvious. Service replacement is the part families miss, and it is why a parent earning zero salary can still need a six-figure policy.
The calculation, step by step
Add up four things, then subtract what you already have.
Income replacement. Take your after-tax annual income that the household actually relies on, and multiply by the number of years your dependents will need it. A parent of a newborn might need 20 or more years. A parent of a high school senior might need five. This is usually the biggest line item. It is why “years of need” matters more than any salary multiplier.
Debts that should die with you. The mortgage is the big one. Add car loans and any private student loans with a cosigner. A payout that retires the mortgage changes the survivor’s monthly budget on day one.
Future lump sums. College is the classic. If funding your kids’ education is part of the plan, put a real number on it per child.
Final expenses. The Insurance Information Institute says to plan for at least $15,000 to cover the funeral and the legal and administrative costs of settling an estate.
Now subtract: existing savings and investments your family could draw on, current life insurance including employer coverage, and any survivor benefits you can reasonably count. What remains is your coverage gap. That gap is the policy you shop for.
Worked example
A 35-year-old earns $70,000 after tax, has a $250,000 mortgage balance, two kids under five, $60,000 saved, and 1x salary coverage through work.
Income replacement for 20 years: $1,400,000 is the brute-force number, though most planners discount it since the payout can be invested. Call it roughly $1,000,000 to $1,200,000. Mortgage: $250,000. College fund: $100,000 for both kids as a placeholder. Final expenses: $15,000. Gross need lands around $1.4 to $1.6 million. Subtract $60,000 in savings and $70,000 of employer coverage, and the gap is roughly $1.3 to $1.5 million.
Round up, not down, when the inputs feel fuzzy. Underinsuring defeats the entire exercise, while the marginal cost of an extra hundred thousand in term coverage is small for healthy applicants. Precision matters less than direction here.
That number startles people. The monthly premium for it usually startles them in the other direction, because 20- or 30-year term life insurance prices large death benefits cheaply for healthy applicants. Quote the real number before you talk yourself down to a rounder, smaller one.
Mistakes that show up over and over
Insuring the income but not the parent at home. Replacing a stay-at-home parent’s childcare and household work costs real money every week, and the institute’s guidance counts it.
Treating employer coverage as a plan. It is typically 1x to 2x salary and evaporates when you change jobs. Own your base coverage personally.
Buying a round number because it sounds big. $500,000 sounds like a fortune until you subtract a $300,000 mortgage and divide the rest across 15 years of groceries.
Set-and-forget. The National Association of Insurance Commissioners’ consumer guidance treats coverage review as routine maintenance. Recalculate at every major life change.
Lock the number, then fund it
Once you know your gap, the shopping is simple: level term for the years the need exists, quoted from at least three insurers. If the premium pinches, find the room in your other fixed bills instead of shrinking the coverage. The fastest candidate in most budgets is the car: drivers who haven’t re-shopped in a couple of years are usually overpaying.
