About the Life Insurance Calculator
This life insurance calculator estimates how much coverage would keep your family financially secure if you died tomorrow. It uses the DIME method — Debt, Income, Mortgage and Education — plus final expenses, then subtracts the savings and life insurance you already have.
It suits parents, homeowners and anyone whose income supports other people, and is most useful when you are buying a term policy, reviewing workplace cover or checking whether an old policy still fits. The rule-of-thumb figure of 10× income is shown alongside so you can see how your needs-based number compares.
Income replacement is your gross income multiplied by the number of years your family would need it — commonly until your youngest child finishes school. It is not discounted for investment returns or raised for inflation, which roughly offset each other; the result is a planning estimate, not a quote.
With the default inputs, the additional coverage needed is $1,210,000.00. Change any value above to recalculate instantly.
How to use the life insurance calculator
- 1Enter the income your family relies on and how many years they would need it.
- 2Add your mortgage balance and any other debts you would want paid off.
- 3Add an education fund for children and an amount for funeral costs.
- 4Enter savings your family could draw on and any life insurance you already have.
- 5Read the additional coverage needed and compare it with the 10× income rule.
Formula and method
The DIME method adds up the money your family would need if your income stopped: non-mortgage debts (D), your yearly income multiplied by the number of years it must be replaced (I × Y), the mortgage balance (M) and future education costs (E), plus funeral and final expenses (F).
Assets that could cover those needs — liquid savings (S) and existing life insurance (L) — are subtracted to give the additional coverage to buy. Income replacement is simply income × years: it is not discounted for the interest the payout could earn or raised for inflation, on the assumption that the two roughly cancel out if the money is invested conservatively.

Worked examples
$85k earner with a mortgage and one child
Ten years of $85,000 income is $850,000. Adding the $250,000 mortgage, $20,000 of debts, $100,000 for education and $15,000 of final expenses gives $1,235,000. Subtracting $25,000 of savings leaves about $1.21 million of coverage to buy.
Workplace cover already in place
Fifteen years of $60,000 income plus the mortgage, debts, education and final expenses total $1,155,000. The $100,000 group policy and $20,000 of savings cover $120,000, leaving $1,035,000 — well above the $600,000 10× rule because of the long replacement period.
Nearly covered: no mortgage, large existing policy
Five years of $120,000 income plus $5,000 of debts and $15,000 of final expenses is $620,000. With a $500,000 policy and $50,000 of savings, only $70,000 more coverage is needed.
Frequently asked questions
How much life insurance do I need?+
A needs-based estimate adds income replacement, debts, your mortgage, education costs and final expenses, then subtracts savings and existing cover. A quick rule of thumb is 10 to 15 times your annual income, but your real figure depends on dependents and debts.
What is the DIME method?+
DIME stands for Debt, Income, Mortgage and Education. You add non-mortgage debts, several years of income, your mortgage balance and children’s education costs to estimate the coverage that would let your family pay everything off and maintain their lifestyle.
How many years of income should life insurance replace?+
A common approach is to replace income until your youngest child is independent — often until age 18 or 22 — or until your spouse reaches retirement. Ten years is a typical starting point; longer periods apply to young families.
Should I count my workplace life insurance?+
Yes, but be aware that group cover through an employer usually ends if you leave the job, and it is often only one or two times salary. Many people buy a personal term policy so their protection does not depend on their employer.
Do stay-at-home parents need life insurance?+
Yes. A stay-at-home parent provides childcare, housekeeping and other services that would cost money to replace. Enter the yearly cost of replacing that work as the income to replace to size a policy.
Is term or whole life insurance better?+
For most families covering a temporary need such as a mortgage or raising children, term life is far cheaper per dollar of coverage. Whole life adds a cash value component and lifelong cover but costs many times more for the same death benefit.
