How the DIME method works
Rules of thumb like “10× your income” are quick, but they ignore the things that actually drive your family's needs: how much you owe, how long your income matters, and what big future costs are coming. The DIME method builds your number from four concrete pieces:
Debt & final expenses
Credit cards, car loans, student loans and personal loans your family would still owe, plus funeral and final medical costs (typically $10,000–$15,000 in 2026).
Income replacement
The yearly income your household would need to replace, for how many years. We discount future years to today's dollars using a conservative real return, so you don't over-buy.
Mortgage
Your remaining mortgage balance, so your family could pay off the house outright and remove the single biggest monthly bill.
Education
A college fund per child. We embed 2026 cost estimates from community college (~$42k total) to private four-year programs (~$245k total).
Add the four together, then subtract what you already have — existing life insurance (including employer group coverage) and liquid savings your family could draw on. What's left is your coverage gap: the headline number this calculator produces. Because needs shrink over time (the mortgage gets paid down, kids become independent), most families cover the gap with affordable level term insurance sized to those years — not a permanent policy.
What about stay-at-home parents?
A parent without a paycheck still has enormous economic value. The replacement-cost method prices what it would take to hire out the work: childcare (≈$16,500/yr per child under five in 2026), before/after-school care, household management, cooking, transportation and family admin. Summed and projected until the youngest child is independent, this routinely lands between $300,000 and $700,000 of coverage need. CoverageCalc has a dedicated stay-at-home-parent mode that runs this math question by question.
Term vs. whole life: which should you buy?
The two products solve different problems. Term life is pure protection: you pick an amount and a length (10–40 years), pay a level premium, and the policy pays out only if you die during the term. Whole life (and other permanent policies) lasts your entire life and builds cash value, but costs roughly 8–12× more for the same death benefit.
| Term life | Whole life | |
|---|---|---|
| Best for | Temporary needs: kids at home, mortgage, working years | Lifelong needs: estate planning, special-needs dependents |
| Cost (35yo, $500k, est. 2026) | ≈ $20–25/mo (20-yr term) | ≈ $350–550/mo |
| Duration | 10–40 years, level premium | Lifetime |
| Cash value | None — it's pure insurance | Grows slowly; loans possible |
| Common advice | “Buy term and invest the difference” | Niche tool; buy deliberately, not by default |
For the vast majority of households running a DIME calculation, the answer is a level term policy matched to the years your family is exposed — which is exactly why this calculator recommends a term length alongside your coverage amount: the longer of (a) years until your youngest child is independent, (b) years left on your mortgage, and (c) your income-replacement window, rounded up to a standard 10/15/20/25/30-year term.
