Life Insurance Needs Calculator
Estimate how much life insurance coverage your family would need using the DIME method — debts, income, mortgage and education.
Content updated August 18, 2026
This is a needs estimate using the DIME method (Debts, Income, Mortgage, Education), not a quote. What an insurer would actually charge depends on your age, health and underwriting, none of which this calculator knows.
DIME stands for Debts, Income, Mortgage and Education, and it is one of the more thorough ways to size a life insurance policy — instead of a flat multiple of salary, it adds up the specific things your family would need to cover and subtracts what you already have to cover them with.
This calculator does not quote a premium and does not know what an insurer would charge you. It answers a narrower, more useful question first: how much coverage would actually close the gap, based on your own numbers.
The Life Insurance Needs formula
Recommended coverage = (other debts + final expenses + mortgage balance + annual income × replacement years + education cost per child × number of children) − existing assets and coveragethe result is floored at zero; each of the four DIME components — Debts, Income, Mortgage, Education — is entered as its own field.
Worked example
15,000 in other debts, 12,000 of final expenses, a 220,000 mortgage, 75,000 of annual income replaced for 10 years, two children at 40,000 of education each, and 50,000 of existing assets and coverage: debts and final expenses are 27,000, mortgage payoff 220,000, income replacement 750,000, and education 80,000, for a gross need of 1,077,000. Subtracting 50,000 of existing assets leaves a recommended coverage of 1,027,000.
Assumptions, rounding, and limitations
Assumptions
- Income replacement is a flat annual income multiplied by a chosen number of years, with no inflation, raise or investment growth applied to it.
- Education cost per child is a single estimate applied equally to every child entered.
- Existing assets and coverage combine savings, investments and current life insurance into one figure that is subtracted from the gross total.
- The mortgage figure is the current payoff balance, not the original loan amount.
Rounding: All figures are computed at full floating-point precision and rounded only for currency display.
Limitations
- This is a needs estimate, not a premium quote — actual policy cost depends on age, health and insurer underwriting.
- Does not model inflation over the replacement period or taxes on any component.
- Treats income, debts and education costs as fixed figures rather than projections that change over time.
- Not personalized financial, insurance or tax advice; revisit the numbers as circumstances change.

What DIME adds together
Debts: non-mortgage balances your family would otherwise have to pay off — credit cards, car loans, personal loans — plus final expenses such as funeral and estate-settlement costs.
Income: your annual income multiplied by the number of years you want it replaced. There is no single correct number of years; common choices range from a few years of transition to until the youngest child is grown, or until your own planned retirement.
Mortgage: the payoff balance, so the family home does not have to be sold to clear it.
Education: a per-child estimate for the education you want to fund, multiplied by the number of children.
Why existing assets get subtracted
Savings, investments and any life insurance you already carry reduce the gap a new policy needs to close. The calculator subtracts these from the gross DIME total to reach a recommended coverage figure, which is floored at zero — if existing assets already cover the need, the tool will not suggest a negative amount.
What this does not account for
The result is a coverage estimate, not a premium quote. What a policy actually costs depends on age, health, tobacco use, policy type and the insurer's own underwriting — none of which this calculator has access to.
It also does not model inflation over the replacement period, taxes on any of the components, or non-financial changes such as a surviving spouse's own future earning changes. Review the numbers periodically, since income, debts and family circumstances change.
Frequently asked questions
▶What is the DIME method for life insurance?
A needs-analysis approach that adds Debts (plus final expenses), Income replacement (annual income × years), Mortgage payoff and Education costs, then subtracts existing assets and coverage to reach a recommended amount.
▶How many years of income should I replace?
There is no universal answer. Some people choose until the youngest child becomes independent, others choose a fixed transition period or until their own planned retirement. The calculator lets you set any number from 0 to 40 years.
▶Does this calculator tell me how much a policy will cost?
No. It estimates how much coverage would close your family's financial gap. The premium for that amount of coverage depends on underwriting factors this tool has no access to — get that from a licensed agent or insurer.
▶Should I include my mortgage in 'other debts'?
No — enter it in the separate mortgage balance field. Keeping it separate makes the DIME breakdown easier to read and matches how the method is usually presented.
▶What if my existing assets are larger than my DIME total?
The recommended coverage is floored at zero rather than shown as negative. That does not necessarily mean you need no life insurance at all — it means this specific DIME calculation does not show a funding gap.
