How much life insurance do I actually need?

If you ask ten different agents how much life insurance you need, you will get ten different answers — and most of them will conveniently land near the maximum policy size their commission structure rewards. The honest answer is that there is no single number that applies to everyone. But there is a process that gets you to a real number for your family, in about twenty minutes, with nothing more complicated than a pencil.

The shortcut nobody should rely on

You have probably heard the rule of thumb: get ten to twelve times your annual income in coverage. It is fine as a starting point. It is terrible as a final answer. A 35-year-old with two young kids and a 30-year mortgage needs very different coverage than a 55-year-old with grown children and a paid-off house — even if they earn the exact same salary. The multiplier ignores everything that actually matters.

The real framework: DIME

A more honest way to size coverage is the DIME method. It stands for Debts, Income, Mortgage, and Education. You add up what your family would actually need to replace if you were not there, and that number becomes the floor for your coverage.

D — Debts

Add up every debt that does not disappear when you die. Credit cards, car loans, personal loans, student loans that are not federal, medical bills. Federal student loans are usually forgiven at death. Most other debts are not. Add a line for final expenses — funeral, burial or cremation, and three to six months of household bills while your family figures out what to do next. Plan on $15,000 to $25,000 here.

I — Income replacement

Take your annual after-tax income and multiply it by the number of years your family would need to lean on it. For a young family with kids at home, that is often 15 to 20 years — long enough for the youngest child to finish school and for your spouse to rebuild their own earning power. For a couple with no children, it might be 5 to 10. The goal is not to make your family rich. It is to give them the time and the room to grieve, replan, and rebuild without a crisis on top of a tragedy.

M — Mortgage

Include the full remaining balance on your mortgage. The point is to give your family the option to stay in the home without scrambling for a refinance during the worst month of their lives. If you rent, include enough to cover 12 to 24 months of rent at current rates.

E — Education

If you have children and you want to fund part or all of their education, add it here. A rough planning number today: $25,000 per year per child for an in-state public college, $50,000 to $80,000 per year for a private four-year. Multiply by however many years you want to cover.

A real example

Picture a 38-year-old earning $90,000 after tax, married, two kids ages 6 and 9, with a $320,000 mortgage and $35,000 in non-mortgage debt. Running DIME:

• Debts and final expenses: $35,000 + $20,000 = $55,000
• Income replacement: $90,000 × 18 years = $1,620,000
• Mortgage: $320,000
• Education: $25,000 × 4 years × 2 kids = $200,000

Total: roughly $2.2 million. That is the actual coverage floor for this family. The classic rule of thumb (12 × $90,000 = $1.08 million) would have left them about $1.1 million short. That is not a small gap. That is the gap that forces a surviving spouse to sell the house and move the kids in with grandparents.

Subtract what you already have

From your total, subtract everything you already have lined up:

• Existing individual life insurance policies
• Group life insurance through your employer (be honest — most group plans are only one or two times your salary)
• Liquid savings and investments your family could draw on
• Social Security survivor benefits (an estimate from ssa.gov is fine)

The number left over is the gap. That is the amount of new coverage you actually need to buy. For most working-age families with kids, the gap is somewhere between $500,000 and $2,000,000 of additional term coverage.

Why term coverage is almost always the right answer for the gap

The job of the coverage we just calculated is to protect your family during the years when they would be financially devastated by your death. That window has a beginning and an end — usually the years when you have young children, a mortgage, and no significant retirement assets. Term insurance is designed exactly for that window. It is cheap, it is simple, and when the window closes, you let it expire. A healthy 35-year-old can typically buy $1 million of 20-year term coverage for $30 to $50 a month.

Permanent insurance — whole life or universal life — has its uses, but covering a 20-year income-replacement gap is not one of them. The same coverage in a permanent policy can cost five to ten times more. If you cannot afford enough coverage to actually protect your family, you have bought the wrong product.

Don't forget the non-earner

If one spouse stays home with children or works part time, they still need coverage. The economic value of childcare, household management, transportation, and meal preparation is real. Replacing it requires money. A reasonable floor for a stay-at-home parent is $250,000 to $500,000 of term coverage. The grieving working spouse cannot do everything alone.

Recalculate every few years

The number you arrive at today is not the number you will need in ten years. Kids grow up. Mortgages get paid down. Income changes. The right cadence is to redo the DIME exercise every three to five years, or after any major life event — a new child, a job change, a new mortgage, a divorce. Keep every policy you currently own and the latest DIME calculation in one place, so when something changes, you know exactly what to update.
