How much life insurance does your household actually need?
The honest answer is: more than the casual rule of thumb suggests, and structured differently than most agents will offer. This calculator runs the three accepted needs-analysis methods — DIME, Human Life Value, and the income multiple — against the same household inputs, so you can see the range a defensible coverage figure should fall within.

Why the casual rules of thumb mislead
The ten-times-income rule has been circulating in personal-finance media for forty years. It is a useful starting heuristic and a poor final answer. The reason: it ignores the structure of household obligations. A 32-year-old earning $95,000 with a $250,000 mortgage, $20,000 of non-mortgage debt, and two children under five faces materially different replacement-income obligations from a 56-year-old earning the same $95,000 with no mortgage, no consumer debt, and adult children long since launched. The same multiplier applied to both produces under-coverage for the first household and substantial over-coverage for the second.
The needs-analysis frameworks below address the structural problem. DIME builds a coverage figure from explicit obligations. Human Life Value computes the present value of the income the working spouse would have contributed to the household over their remaining career. Income multiple is the casual rule formalised. Comparing the three on the same household typically shows that DIME and HLV are closer to each other than either is to the income multiple, and that the income multiple is most often too low for the household with young children and rising expenses, and too high for the household whose obligations have already largely retired.
The DIME method, in components
DIME is an acronym: Debt + Income (replacement years) + Mortgage + Education. Each component answers a specific obligation that survives the insured’s death. The calculator above sums the four components into a total need, then subtracts existing coverage to produce the gap.
Debt
Total non-mortgage debt: credit-card balances, auto loans, student loans, personal loans. The component covers the cost of clearing these obligations so the surviving family is not left servicing them. Some practitioners include only consumer debt and exclude student loans (which may have death-discharge provisions for federal loans); others include everything. The conservative practice is to include everything that the surviving spouse would otherwise be obligated to repay.
Income replacement
Annual gross income times the number of years of replacement. The years figure is judgment: 5 years gets a household to the next major life stage; 10 years gets through children to mid-school age; 15–20 years approximates “to retirement age” for a younger insured. The default in the calculator is 10 years; adjust based on dependents’ ages and the surviving spouse’s capacity to re-earn.
Mortgage
The outstanding mortgage principal. Coverage of this component allows the surviving family to either pay off the mortgage outright or continue payments without the income disruption. Some practitioners argue for excluding the mortgage from DIME on the basis that the income-replacement component already covers the monthly mortgage payment; the conservative practice is to include both, which is over-coverage by design and produces a buffer against unforeseen costs.
Education
Total expected cost of children’s tertiary education, expressed in today’s dollars (inflated to the future-cost figure if you prefer). For two children planning four-year US public university degrees as of 2026, the figure is approximately $180,000–$240,000 in current dollars; for two children planning private universities, $400,000–$600,000. Inflate by 4–5 % per year over the time-to-enrolment for a future-cost target.
The DIME method page walks through a worked example and the boundaries between DIME and the more sophisticated human-life-value framework.
The Human Life Value method
Human Life Value is the present value of the future income the insured would contribute to their dependents over the remainder of their working life. The formula:
HLV = Σt=1n [Income · (1 − Personal Consumption) / (1 + r)t]
Where Income is annual gross income, Personal Consumption is the fraction the insured consumes themselves (typically 25–35 % for an earner with a partner and dependents), n is years remaining to retirement, and r is a real discount rate (typically 2–4 %, reflecting the long-run real return on conservative investment).
The HLV approach captures the economic value of the lost income stream more cleanly than DIME because it accounts for the time value of money explicitly. It typically produces somewhat higher needs figures than DIME for younger insureds with long working lives ahead and somewhat lower for older insureds approaching retirement. The human-life-value page works through the derivation and the discount-rate selection.
The income-multiple shortcut, properly calibrated
The casual ten-times-income rule under-covers most working-age households with dependents. A more defensible income-multiple calibration:
- Single, no dependents, no significant debt: 0× (no need; consider only enough to cover funeral expenses and any debt).
- Married, no children, dual income, modest mortgage: 5–7× for each earner.
- Married, young children, dual income, substantial mortgage: 10–15× for each earner; primary earner toward the higher end.
- Married, young children, single income, substantial mortgage: 12–18× the working income.
- Empty-nest, mortgage-free, near retirement: 3–5× (covering remaining-career income; final-expense and non-mortgage debt only).
The income-multiple approach is the right tool for a quick gut check. For an actual coverage decision, use DIME or HLV and treat the income-multiple result as the sanity check.
The Social Security Survivor Benefit consideration
For US households, Social Security Survivor Benefits represent a partial offset to needed life coverage. A surviving spouse caring for children under 16 is eligible for benefits based on the deceased’s earnings record; surviving children are also eligible until 18 (19 if still in secondary school). For a working-age US insured, the present value of the projected survivor benefit stream is typically $200,000–$500,000 depending on earnings history and ages. Practitioners differ on whether to subtract this from the DIME or HLV need: the conservative practice is to compute coverage without the offset (preserving the survivor benefit as additional safety margin) and the rigorous practice is to subtract it (avoiding over-coverage). The official Social Security Survivors Benefits page provides the calculation tools for your specific earnings record.
Methodology and editorial standards
Calculations follow standard CFP Board needs-analysis conventions and the actuarial-society practice notes on individual life insurance underwriting. The HLV implementation uses ordinary-annuity present value with annual compounding; the DIME and income-multiple methods use straight summation. Reviewer credentials are verifiable on the Society of Actuaries member directory and the CFP Board public certificant directory. Calculation discrepancies are corrected within five business days where reproducible — see the contact page. Editorial corrections are timestamped and an audit trail is retained.
