Life Insurance Needs Calculator

The most common life insurance rule of thumb — buy coverage worth 10 times your income — ignores everything specific to your household: your mortgage, your debts, how many years of income your family actually needs replaced, what you've already saved, and what coverage you already have through work. This calculator uses the DIME method instead: Debt, Income, Mortgage, Education — four real obligations, added up and netted against what you already have.

Worked example, matching this calculator's defaults — $75,000 income, replacing 70% of it for 15 years, $280,000 mortgage, $15,000 other debts, $15,000 final expenses, $100,000 education fund, $60,000 existing savings, no existing coverage, 4% return on the invested payout:

• Annual income to replace: 70% × $75,000 = $52,500
• Income replacement, as a lump sum: rather than simply multiplying $52,500 × 15 years ($787,500), the calculator finds the present value of that 15-year income stream, assuming the payout is invested at 4%. That's $583,715.34 — a smaller number, because an invested lump sum earns its own return while it funds the payments.
• Debts and final expenses: $280,000 + $15,000 + $15,000 = $310,000
• Plus education fund: $100,000
• Gross need: $993,715.34
• Less existing savings and coverage ($60,000): Net need of $933,715.34

Compare that to the 10x-income shortcut, which would suggest just $750,000 here — underinsuring this household by nearly $184,000 relative to its actual obligations. The gap runs the other direction for households with smaller mortgages or grown children; the shortcut has no way to know either way.

The calculator also attaches an illustrative premium range — deliberately a range, not a single number, because the spread between health rating tiers at the same age is roughly double. For a 40-year-old male nonsmoker buying $933,715 of 20-year level term coverage, national average annual premiums run from about $599/year at "preferred plus" (the healthiest rating tier) to $1,178/year at "standard" — a monthly range of roughly $50 to $98.

This is an average built from published broker rate data (source and valid-as-of date shown on the calculator's result), not a quote — no calculator can quote an insurance premium, because insurers price off their own underwriting once you apply. Age, sex, and tobacco use move this range substantially; smoker rates on this table run roughly 3-4x the nonsmoker rate at the same age.

Term vs. Whole Life, in One Sentence

Term insurance — what this calculator prices — covers a fixed period at a much lower premium and fits most people whose need is temporary: until the mortgage is paid off and the kids are financially independent. Whole life costs substantially more and adds a cash-value savings component, which mainly makes sense for a genuinely permanent need, like estate liquidity, rather than as a default choice.
