Life Insurance Needs Calculator

How the life insurance calculator works

This tool explores a life-insurance coverage amount using the DIME planning heuristic: Debt, Income, Mortgage, and Education. DIME is a checklist, not a rule issued or endorsed by an insurance regulator. It adds four selected obligations and subtracts entered resources to show a possible gap.

The math is direct. The gross need is debt + (annualIncome × yearsToReplace) + mortgage + education. The income leg is a simple, undiscounted replacement: your annual income multiplied by the number of years you want to cover. The recommended new coverage is then need = max(0, grossNeed − liquidAssets − existingCoverage). The result is floored at zero, so when your assets and current policies already exceed the gross need the tool returns nothing to buy. When you net out assets or existing coverage, the method is labelled DIME+.

Worked example

A household enters these figures: $20,000 in non-mortgage debt, $60,000 annual income to replace for 10 years, a $250,000 mortgage, and $100,000 of future education funding. They have $50,000 in liquid assets and $100,000 of existing coverage.

Step	Calculation	Amount
Debt	given	$20,000
Income	60,000 × 10	$600,000
Mortgage	given	$250,000
Education	given	$100,000
Gross need	sum of the four legs	$970,000
Less liquid assets	− 50,000	−$50,000
Less existing coverage	− 100,000	−$100,000
Recommended coverage	970,000 − 150,000	$820,000

The gross DIME total is $970,000. After subtracting $150,000 of assets and current coverage, the scenario shows an $820,000 gap. That is not a recommendation to purchase that amount or any particular product. Because offsets were applied, the calculator labels the method DIME+.

How to use it

• Enter the mortgage payoff balance separately from other debt, and put cards, auto, and student loans in the debt field.
• Set years to replace to how long your family needs the income: until the youngest child finishes school, or until a partner reaches retirement, are common anchors.
• Use education for the full expected cost of each child’s schooling, not the amount saved so far.
• List only liquid assets you would actually spend down, such as cash, brokerage accounts, and accessible savings. Skip retirement accounts you want left untouched.
• Add employer and private policies under existing coverage so the result is the new amount to buy, not your total.

Limitations

This is a simplified estimate, not insurance, financial, tax, or estate-planning advice. The income leg is undiscounted: it does not model inflation, investment return, survivor earnings, Social Security or pension benefits, taxes, changing expenses, or the time value of money. Unless manually included, it also omits funeral costs, childcare, final expenses, caregiving, business obligations, estate liquidity, and lifelong dependents. Employer coverage may be limited or may end with employment.

Review how obligations and resources change over time, compare policy terms and guarantees, and verify the financial strength and licensing status of an insurer or producer through the relevant state insurance department. The NAIC recommends evaluating family income, changing obligations, and how long death benefits will be needed.
