Life Insurance Needs Calculator
Size your cover the DIME way — Debt, Income, Mortgage, and Education, minus what your family already has — for a clear, obligation-based number. See it side by side with the 10× rule of thumb, plus an illustrative 20-year term premium built from real rate tiers.
Educational estimate, not financial advice — the premium is illustrative and not a quote. Get real quotes and confirm your number with a licensed professional before buying.
Roughly the years until your youngest is grown — the DIME “Income” horizon. Adjust to your family.
Final-expense costs are added automatically ($8,300, NFDA median funeral + burial).
Default ≈ 4 years of public in-state cost of attendance (College Board 2025-26). Varies by state; drops after aid.
Include any employer group cover — but note it often isn’t portable if you change jobs, so it may not be there when your family needs it.

DIME and the rule of thumb disagree by 60%
Your DIME need ($1,890,000) and the 10× estimate ($750,000) are far apart — usually a large mortgage, several children, or a non-earning parent. The 10× shortcut can badly under- or over-shoot in these cases. Consider a licensed professional before settling on a number.

Method & sources
DIME need = (Debt + final expense) + Income × years + Mortgage + Education × children − (existing savings + existing cover), floored at zero and rounded to the nearest $10,000. The 10× figure is a rule-of-thumb cross-check. The monthly premium is interpolated between published rate tiers — premiums do not scale linearly with coverage — for a healthy non-smoker, 20-year level term, Preferred health class, and is illustrative, not a quote.

How we calculate this
This calculator uses the DIME method, a standard way to size income-replacement life insurance for a working parent (see NerdWallet and Guardian). It adds four things your family would need to cover and subtracts what they already have:
- D — Debt. Your non-mortgage debts (credit cards, auto, student, and personal loans) plus a final-expense cushion. We fold in $8,300, the NFDA’s 2023 median cost of a funeral with burial.
- I — Income. Your annual income times the number of years your family would need it — usually the years until your youngest is grown.
- M — Mortgage. The remaining balance, so the family can clear the home loan.
- E — Education. A fund per child. The default of about $130,000 is roughly four years of public in-state total cost of attendance — $30,990 a year for 2025-26 per the College Board. It’s an average that varies by state and drops after aid, so adjust it to your plans.
From that gross total we subtract your existing savings and any life cover already in force to leave the net amount to buy. A word on existing cover: employer group life often isn’t portable, so it may not follow you to your next job — treat it as a bonus rather than a guarantee.
Next to the DIME figure we show the 10× incomerule of thumb. It’s a quick sanity check, not the answer: it ignores your mortgage and how many children you’re educating, so it can badly under-insure a large-mortgage or multi-child family, and it returns almost nothing for a non-earning parent — who still needs cover. When DIME and 10× diverge by more than about 30%, the tool flags it and suggests a professional review.
The premium is illustrative, never a quote.It’s interpolated from published rate tiers (Policygenius Price Index, February 2025) for a healthy non-smoker on 20-year level term. Because premiums don’t scale linearly with coverage — there’s a fixed policy cost, so the price per $1,000 falls as cover rises — we interpolate between tiers rather than multiply a constant rate. Smokers pay roughly three times more; women pay roughly 15–23% less than men. Figures last reviewed July 2026.
How to use the result
Treat the DIME figure as your starting target and the premium as a reality check on affordability — most young families find that 20-year term buys a large amount of cover for a modest monthly cost. Term life, matched to the years your family depends on your income (commonly 20–30 years for a new parent), is the usual fit for income replacement. Then get real quotes from two or three insurers: your actual price turns on age, health, tobacco use, and the insurer’s own underwriting.
This tool sizes cover for a working parent’s income. If one parent stays home, their unpaid work — childcare, cooking, driving, and household management — still needs replacing; our Stay-at-Home Parent Value Calculator puts a dollar figure on that. For a faster, income-only estimate with a US/CA/UK toggle, the Life Insurance Calculator gets you a ballpark in about ten seconds.
Frequently asked questions
DIME is a four-part checklist for how much life insurance replaces when a working parent dies: Debt (non-mortgage debts plus final expenses), Income (your annual income times the number of years your family would need it), Mortgage (the balance to pay off so they can keep the home), and Education (a fund per child). You add the four together, then subtract what the family already has — liquid savings and any existing cover — to get the net amount to buy. It's more thorough than a flat income multiple because it looks at your actual obligations, not just your paycheck.
The 10× rule (buy ten times your income) is a fast sanity check, and this tool shows it right next to the DIME figure. But it's only a shortcut. It ignores your mortgage and how many children you're putting through school, so it under-insures families with a big mortgage or several kids — and it returns almost nothing for a non-earning parent, who still needs cover. Use DIME as the real number and the 10× as a gut check. When the two disagree by more than about 30%, the calculator flags it and suggests a professional review.
They're illustrative, not quotes. The figure is interpolated from a published rate table (Policygenius Price Index, February 2025) for a healthy non-smoker on a 20-year level term. Crucially, premiums do not scale linearly with coverage — there's a fixed policy cost, so the price per $1,000 falls as the amount rises. Doubling the cover does not double the premium. Your actual price depends on age, health, tobacco use, term length, gender, insurer, and your state — smokers pay roughly three times more, and women pay roughly 15–23% less than men. Always get real quotes.
The default is about $130,000 per child, which is roughly four years of the total cost of attendance at a public in-state university — $30,990 a year for 2025-26, per the College Board. That's an average: private colleges run far higher (about $65,470 a year), costs vary widely by state, and grants and scholarships often bring the net price down. Adjust the figure to the kind of education you're planning for, or set it to zero if you'd rather size cover for income and debts alone.
You can enter it under cover you already have, but treat it with caution. Employer group life is usually not portable — if you change jobs or are laid off, it typically doesn't come with you, so it may not be there when your family actually needs it. Many planners suggest owning enough individual cover to stand on its own and treating group cover as a bonus on top, rather than subtracting it dollar-for-dollar from what you buy.
For income replacement in a young family, term life is the usual fit, and the term is typically matched to how long your family depends on your income — often 20 to 30 years for a new parent, long enough to cover the years until the children are grown and the mortgage is paid. The illustrative premium here assumes a 20-year level term. A level term keeps the same premium for the whole period, which makes budgeting simple.
