The most common answer you will hear is ten times your income. It is a reasonable starting guess and a poor final answer, because it ignores whether you have a mortgage, whether your children are two or seventeen, and whether your spouse earns more than you do. Twenty minutes of arithmetic gets you a defensible number instead.
The DIME framework
DIME stands for Debt, Income, Mortgage, Education. Add the four, subtract what you already have, and the remainder is what you need to buy.
Debt
Everything except the mortgage: car loans, credit cards, student loans, personal loans, medical debt. Add final expenses on top. Funeral and burial costs commonly run several thousand dollars, and there are usually estate and administrative costs on top of that. Use a realistic figure rather than a comfortable one.
Income
This is the largest piece and the one people underestimate. Take the annual income your household would lose and multiply it by the number of years it needs to be replaced. Choose that number of years deliberately: until the youngest child finishes school, or until the surviving spouse reaches retirement age, whichever fits your situation.
Two adjustments matter. First, if your spouse works, replace only the gap between household need and their income, not your full salary. Second, do not forget the non-earning contribution. If one parent is at home, replacing the childcare, transportation, and household work they provide is a genuine cost, often $30,000 to $50,000 a year depending on where you live and how many children you have.
Mortgage
Use the current payoff balance, not the original loan amount and not the home's value. Call the servicer or read the last statement. If your intent is that the family stays in the house, this line should let them stay without a payment.
Education
If you intend to fund college, estimate per child and subtract what is already in a 529 or similar account. Be honest about what you are actually promising. Four years at an in-state public university and four years at a private university are very different numbers, and picking one now is better than pretending the question does not exist.
Subtract what already exists
From the total, subtract:
- Liquid savings and non-retirement investments that the family could actually spend.
- Existing individual life insurance policies.
- Employer group life, with a caveat. Group coverage is typically one or two times salary and it ends the day the job ends. Count it, but do not build the plan on it.
- Survivor benefits your household would qualify for, if you know the amount. These can be meaningful for families with young children.
Do not subtract retirement accounts you want left alone for the surviving spouse's retirement. If you subtract them, you are quietly deciding that the survivor spends their retirement funding the next fifteen years, which is usually not the plan.
A worked example
A household with two children aged 6 and 9. The higher earner makes $95,000; the spouse makes $45,000.
- Debt and final expenses: $28,000 in car and consumer debt plus $15,000 final expenses equals $43,000.
- Income: the gap to cover is roughly $70,000 a year for 16 years, until the younger child is out of school, which is $1,120,000.
- Mortgage: $265,000 payoff balance.
- Education: $150,000 for two children, less $30,000 already saved, equals $120,000.
Total need: $1,548,000. Subtract $60,000 of savings and $190,000 of group coverage at two times salary, and the gap is roughly $1,300,000. Rounded, that household should be shopping a $1.3 million term policy, not the $250,000 they probably assumed.
That number looks alarming until you price it. Level term for a healthy person in their thirties is priced per thousand of coverage at a rate low enough that the difference between $500,000 and $1,300,000 is often smaller than people expect. Get a quote at the number the math produced before deciding it is unaffordable.
Structure it as a ladder
The full $1.3 million is not needed for the entire period. The education piece expires when the children finish school; the mortgage piece shrinks with the balance. Buying a 30 year policy for the mortgage layer and a 20 year policy for the income and education layer keeps coverage highest during the years of greatest exposure and drops the premium substantially compared to one long policy at the full amount.
Then check it every few years
Re-run the four lines after any of these: a new child, a new mortgage, a significant income change, a divorce, or paying off a major debt. And confirm your beneficiary designations at the same time. A policy that pays the wrong person is a common and entirely avoidable failure, because the beneficiary form controls regardless of what your will says.
