Life Insurance Needs Calculator
How much life insurance does your family actually need? This calculator uses the well-known DIME method to turn your real obligations — debts, income, mortgage, and education — into a coverage target, then subtracts what your family already has.
How this calculator works
DIME adds up the four things your income currently covers that would need funding if you were gone:
- D — Debt: non-mortgage debts (car, student, cards) to clear.
- I — Income: your annual income times the number of years your family would need it replaced.
- M — Mortgage: the remaining balance, so the home is secure.
- E — Education: estimated future education costs per child.
total need = Debt + (Income × Years) + Mortgage + Education
We then subtract money your family already has available — savings, assets, and any existing life insurance — to estimate the additional coverageyou’d need to buy:
additional = total need − (savings + existing coverage)
How to think about it
DIME is a sensible starting estimate, not a precise prescription. The biggest lever is the income-replacement years: choose enough to carry your family until the kids are independent or a partner reaches retirement. Most families find that affordable term insurance covers this need — see our guide on the difference between term and whole life for why.

Frequently asked questions
- What is the DIME method?
- DIME stands for Debt, Income, Mortgage, and Education — the four obligations a life insurance payout typically needs to cover. Adding them gives a grounded estimate of how much coverage protects your family.
- How many years of income should I replace?
- Enough to bridge your family to financial independence — commonly 10–20 years, or until your youngest child is grown and/or a spouse reaches retirement. Longer horizons raise the coverage amount.
- Should I subtract my savings?
- Yes. Money your family could already draw on — savings, investments, and any existing policy — reduces the new coverage you need to buy. This calculator does that to estimate the gap.
- Is this a quote or an offer?
- No. This is an educational estimate of coverage need only. We don't sell insurance, collect your details, or provide quotes. Take the figure to a licensed, ideally fee-only, advisor to shop policies.
