Life Insurance Needs Calculator
Calculate exactly how much life insurance your family needs. Goes beyond the "10x salary" rule of thumb to model your actual income replacement needs, debts, childcare costs, education funding, and existing coverage.
Based on the DIME method: Debts + Income replacement + Mortgage + Education — the most comprehensive approach to calculating life insurance needs.

How to calculate life insurance needs
The DIME method is the most thorough approach to calculating life insurance coverage: Debts + Income replacement + Mortgage + Education. Each component represents a real financial obligation your family would face without your income.
Income replacement is typically the largest component. The goal is to give your surviving spouse a lump sum that, invested at a reasonable return, generates enough income to replace your contribution to household expenses until retirement. A $70,000/year income replacement need at 5% return requires a $1,400,000 lump sum ($70,000 ÷ 0.05).
The 10× salary rule of thumb is a quick estimate but often undershoots for young families with large mortgages, many children, or high debt. The DIME method produces a more accurate figure by addressing each specific need rather than using a blanket multiplier.
lightbulb Term vs. Permanent Insurance
Term life insurance provides coverage for a specific period (10, 20, or 30 years) at a fixed premium. It’s the most affordable way to get maximum coverage during your highest-need years — when you have young children, a mortgage, and decades of income to protect.
Permanent life insurance (whole life, universal life) provides lifetime coverage with a cash value component. It costs significantly more than term for the same death benefit. Most financial planners recommend term insurance for income replacement needs, with permanent insurance serving specific estate planning or business needs.
For most families, the strategy is: buy enough term life to cover the DIME needs, invest the premium difference between term and whole life, and reassess coverage as needs decrease over time.
Life Insurance FAQs
How long should my term policy be?
Match the term to your longest financial obligation. If your youngest child is 3 and you want coverage until they finish college, a 20-year term covers you to age 23. If you have 25 years on a mortgage, a 30-year term covers it. Most families with young children are best served by 20–30 year term policies that extend past retirement. Once your mortgage is paid and children are independent, your insurance need drops dramatically.
Should both spouses carry life insurance?
Yes — even a non-working spouse provides significant economic value through childcare, household management, and other services. The cost to replace those services (childcare, housekeeping, transportation, meal preparation) can easily exceed $50,000–$80,000 per year. A policy on the non-working spouse should cover at least several years of those replacement costs.
Is employer-provided group life insurance sufficient?
Rarely. Group policies typically provide 1–2× salary — a fraction of what most families need. They also end when you leave the job, aren’t portable, and can’t be customized. They count toward your coverage but almost never replace the need for a private term policy.
Terminology
DIME Method
Debts + Income replacement + Mortgage + Education. A systematic approach to calculating life insurance needs by quantifying each specific financial obligation, producing a more accurate figure than simple salary multiples.
Income Replacement (Present Value of Annuity)
The lump sum needed today to generate a target annual income indefinitely (or for a set period). For an indefinite income stream: lump sum = annual income ÷ expected return rate. For a finite period, use the present value of annuity formula.
Human Life Value
An alternative calculation method: the present value of all future earnings to retirement, discounted at an expected rate. Represents the total economic value of your working life. Tends to produce higher coverage amounts than DIME for high earners.
Death Benefit
The amount paid to beneficiaries upon the insured’s death. Federal income-tax free to beneficiaries under current law.
