What This Calculator Does

The Life Insurance Coverage Calculator uses the DIME method — a widely used framework among financial planners — to estimate how much term life insurance you should carry to protect your family financially if you were no longer there to provide for them.

DIME adds together four components: your outstanding Debt (excluding mortgage), the Income your family would need replaced for a set number of years, your remaining Mortgage balance, and future Education costs for your children. It then subtracts any existing life insurance and savings to arrive at the additional coverage you should shop for.

Formula

Net Need = (Debt + Income×Years + Mortgage + Education) − Existing Coverage − Savings

Each component of DIME represents a financial obligation your family would face. Income replacement is typically calculated for 5-15 years — long enough to give a surviving spouse time to adjust, retrain, or rebuild savings. Education costs are commonly estimated at $40,000-$120,000 per child depending on public vs. private college plans.

  • DebtCredit cards, auto loans, personal loans, and other non-mortgage debt
  • Income × YearsAnnual income multiplied by the number of years your family would need it replaced
  • MortgageRemaining balance on your home loan
  • EducationEstimated college/education cost per child × number of children

Examples

Example 1: Young family with a mortgage

$15,000 debt, $70,000 income × 10 years, $250,000 mortgage, 2 kids at $60,000 education each, $50,000 existing coverage, $20,000 savings.

DIME total = $15,000 + $700,000 + $250,000 + $120,000 = $1,085,000. Net need after subtracting $70,000 = $1,015,000 — roughly a $1M term policy.

Example 2: Single income, no kids

$10,000 debt, $90,000 income × 7 years, $180,000 mortgage, 0 kids, no existing coverage.

DIME total = $10,000 + $630,000 + $180,000 = $820,000. A $750K-$850K, 20-year term policy would cover this need at an estimated $450-$470/year for a healthy applicant in their 30s.

Example 3: Pre-retirement, mortgage paid off

$5,000 debt, $100,000 income × 5 years, $0 mortgage, 1 kid at $50,000 education, $200,000 existing coverage + savings.

DIME total = $5,000 + $500,000 + $0 + $50,000 = $555,000. Net need after subtracting $200,000 = $355,000 — a smaller, shorter-term policy may suffice.

Methodology

DIME need = Debt + (Annual Income × Income Replacement Years) + Mortgage Balance + (Number of Children × Education Cost per Child). Net coverage need = DIME total − Existing Life Insurance − Existing Savings/Investments. Estimated premium uses an illustrative rate of $0.55 per $1,000 of 20-year level term coverage per year for a healthy applicant in their 30s-40s — actual quotes vary by age, health, and term length.

Frequently Asked Questions

What is the DIME method?+

DIME stands for Debt, Income, Mortgage, and Education. It's a simple framework for estimating how much life insurance coverage you need by adding up your outstanding debts, the years of income your family would need replaced, your remaining mortgage balance, and future education costs for your children — then subtracting any existing savings and life insurance.

How much life insurance do I actually need?+

A common rule of thumb is 10–12x your annual income, but the DIME method is more precise because it accounts for your specific debts, mortgage, income replacement years, and children's education costs. Most families land somewhere between $500,000 and $2,000,000 in coverage.

Term vs. whole life — which should I choose?+

Term life insurance covers you for a fixed period (10–30 years) at a much lower cost and is the right choice for most people who need coverage during their working years and while raising a family. Whole life builds cash value but costs 5–15x more for the same death benefit, and is typically better suited for estate planning than pure income replacement.

Do I need to subtract existing savings and coverage?+

Yes. Any existing life insurance through work, retirement accounts, or other savings reduces the new coverage you need to buy. This calculator subtracts your existing assets and coverage from the total DIME need to give you a net coverage recommendation.
