Use the DIME method to calculate your life insurance needs with precision. This approach considers your debts, income replacement needs, mortgage balance, and education funding to determine the right coverage amount, factoring in spouse income and Social Security benefits.
Life insurance is income protection for the people who depend on your income. The question every working parent or primary earner should answer once: if I die unexpectedly, how does my family pay the mortgage, cover groceries, fund college, and avoid being forced to sell the house or radically downsize lifestyle? The right amount of life insurance is the amount that would let them keep their plans intact.
The DIME method is a structured way to answer that question by adding up four categories of need: Debt (pay off all non-mortgage debt), Income (replace your earned income for the years until kids are independent or your spouse can otherwise sustain), Mortgage (pay off the home so housing is secure), and Education (fully fund college for each child). The total, minus what your family already has (existing life insurance plus liquid savings), is what you need to buy. The result is usually larger than the casual "10× income" rule of thumb suggests — and much larger than most people's actual coverage.
This calculator implements the DIME method with two extensions: it accounts for spouse income (which reduces the income-replacement need) and Social Security survivor benefits (a real benefit most families forget about). It also includes childcare — often the single biggest unplanned expense when one parent dies, especially if the surviving parent has been the secondary earner. The output is a specific dollar coverage target; from there, term life insurance at the right amount and term length is usually the right product.
Age 32, primary earner $90K, spouse $20K (part-time), 2 kids ages 3 and 5. D: $40,000 (student loans + car) I: ($90K − $20K) × 18 = $1,260,000 (replace until youngest is 21) M: $325,000 E: $80,000 × 2 = $160,000 Childcare: $14,000 × 12 = $168,000 Funeral: $15,000 Subtotal: $1,968,000 SS survivor: $1,800/mo × 12 × 18 = $388,800 Existing coverage: $50K (employer 1× salary) Savings: $25K Need = $1,968,000 − $388,800 − $50,000 − $25,000 = $1,504,200 Round up to a $1.5M, 20-year term policy. Typical cost for a healthy 32-year-old non-smoker: ~$50–$80/month.
Age 45, primary earner $130K, spouse $95K, kids ages 12 and 15. D: $25,000 (cars) I: ($130K − $95K) × 8 = $280,000 (replace until youngest is 21) M: $200,000 E: $100,000 × 2 = $200,000 Childcare: $0 (kids old enough) Funeral: $20,000 Subtotal: $725,000 SS survivor: $1,600/mo × 12 × 8 = $153,600 Existing coverage: $200K (employer 1.5× plus a small individual policy) Savings: $200K Need = $725,000 − $153,600 − $200,000 − $200,000 = $171,400 A modest $250K, 10-year term policy covers the gap. Mid-career two-income households with substantial savings often need much less coverage than younger families.
Age 35, primary earner $110K, spouse stay-at-home with 3 kids ages 2, 5, and 8. For the stay-at-home parent's policy (replacing the value of unpaid work): Replace childcare: $18,000/year × 10 years = $180,000 Replace household labor (cooking, cleaning, transportation): ~$15,000/year × 10 = $150,000 Funeral: $15,000 Total: ≈ $345,000 A $500K policy on the stay-at-home parent gives the working spouse the resources to hire help, cut work hours, or take leave without devastating household finances. Often overlooked but extremely high-leverage.
Use this calculator at any major life inflection point: getting married, having a baby, buying a home, taking on substantial debt, starting a business, going through divorce, or any major income change. Most working adults should re-evaluate coverage every 3–5 years and any time the household balance sheet changes meaningfully.
It's especially important when transitioning out of employer-provided coverage. Most employer life insurance is 1–2× annual salary — typically far less than the DIME calculation indicates is needed. Worse, employer coverage usually terminates at job change, so relying on it leaves a gap whenever you change jobs.
Pair this with the life-insurance-needs calculator (a simpler approach for quick estimates), the disability-insurance calculator (disability is statistically more likely than death during working years and often inadequately covered), and the retirement-savings calculator (since a strong retirement plan reduces the years-to-replace input).
Choosing the product matters as much as the amount. For income replacement, **term life insurance** at the right amount and length (typically 20- or 30-year level term to match your kids' dependency or your working life) is almost always the right choice. It's pure protection at the lowest cost — a 35-year-old healthy non-smoker can buy $1M of 20-year term for $30–$60/month. Permanent insurance (whole life, universal life) bundles a savings component at high cost and is rarely the right tool for income replacement; it's suited to specific estate planning or business needs, not the typical family situation.
