What is the DIME method and is it the right framework?

DIME stands for Debts + Income + Mortgage + Education — the four legs of need that life insurance addresses for a working parent. It’s the framework every fee-only fiduciary planner uses because it captures the actual dollar exposures rather than relying on the ‘10× income’ rule of thumb that misleads two-earner households (which need less because the surviving spouse’s income covers part of the load) and empty-nesters (who often need very little because savings handle the residual). The calculator runs the full DIME math, nets out spouse income and existing savings, and then surfaces the gap vs. your current policy. The output is the dollar amount of additional term coverage to buy — concrete, not an opinion.

Why does the calculator subtract spouse income?

Because if your spouse continues to work after your death, that income covers part of the household’s ongoing needs — and a policy that ignores it would over-insure you. A single-earner family needs to replace 100 % of the deceased’s income to maintain lifestyle. A two-earner family where the deceased made 60 % of household income only needs to replace the 60 % delta, not 100 %. The calculator multiplies spouse income by your replacement-years target and subtracts it from the gross need. Set spouse income to $0 if you’re the only earner or if your spouse plans to stop working after the loss.

What about the ‘10× annual income’ rule of thumb?

It’s a heuristic that’s right for the median single-earner working parent and wrong for many edge cases. A two-earner family with school-age kids and a paid-off house probably needs 5-7×. A single earner with toddlers, a $400K mortgage, and a stay-at-home spouse needs 12-18×. A retiree with grown kids and adequate savings needs 0-2×. The rule produces wildly off coverage in either direction at the tails. The DIME-method calculator gives you the actual number; the calculator also surfaces the multiple-of-income figure so you can sanity-check it against the heuristic.

Should I buy term or whole life?

Term, almost always, for the protection function. Term life buys $X of death benefit for $Y per year for a fixed window (10/15/20/30 years) at a fraction of the cost of permanent insurance — a healthy 35-yr-old non-smoker pays roughly $25-40/mo for $1M of 20-yr term. Whole life bundles a savings vehicle into the premium at industry-mediocre returns and 5-10× the cost; the only situations where whole life makes financial sense are estate-tax planning at the $13M+ exemption level and special-needs trust funding. For 95 % of households, the right structure is term life sized to the DIME need + invested savings outside the policy. The calculator’s premium estimate is for term — multiply by 8-12× for a whole-life equivalent.

What is laddered term and should I use it?

Laddering is buying multiple term policies with different end dates so coverage tapers down as your need shrinks. Example: $750K of 30-yr term + $250K of 15-yr term = $1M of coverage today, $750K after year 15 (when kids finish college and the mortgage is half-paid). Total premium across both policies is typically 15-25 % less than buying $1M of 30-yr term outright, because half your coverage drops off at the cheaper 15-yr price point. Worth doing for needs above $750K and a clear taper schedule. Below that, a single policy at the longest needed duration is simpler and barely costs more.

How accurate is the premium estimate?

Conservative — calibrated for a healthy non-smoker in their 30s buying 20-yr term. The midpoint is $0.50 per $1,000 of coverage per year. A 35-yr-old non-smoker buying $1M of 20-yr term typically pays $480-650/yr (varies by state, carrier, exact health profile). Smokers pay 2-3× more. Age 50 buys at 3-4× the 35-yr rate. Anyone with chronic conditions (diabetes, BP-medicated hypertension, history of cancer) gets rated up — pricing varies wildly by carrier specialty. The calculator’s estimate is an order-of-magnitude check, not a binder. Get real quotes from 3-5 carriers via a fee-only broker or a marketplace before purchasing.

Does my employer’s group life count?

Yes, but with a major caveat: it ends when employment ends. The typical group life policy is 1-2× salary — meaningful for a $200K earner (so $200-400K of coverage), but it disappears the day you change jobs, get laid off, or retire. The calculator’s ‘existing policy’ field includes employer group life, but if your job change is plausible inside the next 5 years, treat the group portion as a temporary supplement and buy enough individual term to cover the full gap if it disappeared tomorrow. Job-stable + same-employer-for-decades workers can include group life; everyone else should buy as if it doesn’t exist.

What about the spouse’s coverage?

Run the calculator twice — once with you as the insured, once with your spouse. Each policy sized to its own DIME math. Two-earner couples often discover the lower earner needs more coverage than they expected, because eliminating the lower income still leaves the family with a real shortfall against fixed obligations (mortgage, education funding, savings rate). Stay-at-home spouses absolutely need coverage — replacing childcare, household management, and logistics costs $40-60K/yr in markets like SF/NY/DC, and life-insurance proxies for that obligation. Don’t skip insuring a non-working spouse on the assumption that they’ll ‘just keep doing what they’re doing.’

How does this interact with estate-tax planning?

For 99 % of families, it doesn’t — the federal estate-tax exemption is $13.6M per person ($27.2M per couple) in 2026 and rising. Below that, life-insurance proceeds pass tax-free to named beneficiaries and there’s no estate-tax angle. Above the exemption, ILIT (irrevocable life insurance trust) structures keep the death benefit out of the taxable estate. State estate taxes have lower thresholds in some states (MA $2M, OR $1M, WA $2.2M) — meaningful for high-asset households, irrelevant for typical middle-class buyers. The calculator’s output is the protection-need number; estate-tax structuring is a separate conversation with an estate attorney.

Why does the calculator use lump-sum education cost instead of monthly?

Because the policy pays a death benefit as a lump sum, and survivors then invest the funds and spend them over time. Mathematically equivalent: $480K policy → invest at 5 % → withdraw $30K/yr for 4 years × 4 dependents starting at age 18 vs. immediate $480K disbursement. The lump-sum input keeps the math honest and lets you input today’s sticker price for college without compounding inflation guesses on top. If you want to be more conservative, multiply your education-cost input by 1.3 to account for 7 years of college-cost inflation between now and a 5-yr-old’s freshman year.

What if my income is uneven (commission, freelance, business owner)?

Use a 3-year average of net business income. Insurance carriers underwrite based on documented earnings, and they’ll pull your last two tax returns; if your 2024 was $80K and 2025 was $250K, they’ll likely use ~$165K as the underwriting income — and that’s the right number for the calculator too. Don’t enter your peak year (over-insures during a slow year, blows premium budget) or your trough (under-insures during a peak year). For S-corp owners, use net business income + W-2 — the combined figure that flows to your 1040.

Life Insurance Needs Calculator — DIME Method + Coverage Gap + Premium Estimate

Drop your income, dependents, mortgage, education-funding plan, savings, spouse income, and target replacement years. Calculator returns recommended coverage today using the industry-standard DIME framework (Debts + Income + Mortgage + Education) net of liquid assets and spouse’s continuing earnings, the gap vs. any existing policy you have, the coverage as a multiple of income, and a 20-year term-life premium estimate so you know roughly what the right amount of coverage costs. Built on the framework every fee-only fiduciary uses — not the ‘buy 10× income’ oversimplification that under-protects two-income families and over-protects retirees.

Your annual income (gross)

Gross W-2 / 1099 income before taxes. The income-replacement leg of DIME multiplies this by your replacement-year target. Use total household earned income from your side if you carry the larger share, otherwise enter your own.

Spouse / partner annual income

Income your spouse will continue earning after your death. Subtracted from the income-replacement leg — a two-earner household needs less coverage than a single-earner because the surviving partner’s income carries part of the load. Enter $0 if you’re the only earner.

Income replacement years

How many years of income to replace. Standard guidance: until the youngest dependent finishes college, plus a buffer. Single income with toddlers → 20-25 yrs; teens → 10 yrs; adult kids → 5 yrs. Empty-nesters with retirement on the horizon often need 0 — savings handle it.

Number of dependents

Children, aging parents, or anyone else who relies on your income for daily living. Drives the education-funding leg. Spouses are not counted here — their income is captured in the spouse-income field above.

Education funding per dependent

Lump sum to fund each dependent’s post-secondary education in today’s dollars. US in-state public 4-yr ~$110K, out-of-state ~$180K, private ~$320K (CollegeBoard 2025). Enter $0 if education funding sits outside the policy (529 plan, scholarships, no-college path).

Outstanding mortgage balance

Current principal balance (not original loan amount). The DIME method covers a lump-sum payoff so survivors keep the home without the monthly P&I burden. Pull the figure from your latest mortgage statement — most show payoff as a separate line.

Final expenses budget

Funeral + estate-settlement + immediate liquidity buffer for the first 30-60 days. Industry median ~$15-25K. Higher if you want a memorial event funded; lower if you’ve pre-paid funeral arrangements or have a separate burial policy.

Liquid savings available

Cash, brokerage, and retirement accounts that survivors could access. Directly offsets coverage need — a $1M need shrinks to $700K if you’ve already saved $300K. Excludes home equity (illiquid), business equity (illiquid), and accounts your spouse already owns separately.

Existing life insurance face value

Current term + whole life policies combined. Includes employer group life (typically 1-2× salary). The calculator subtracts this from the recommended coverage to surface the gap — the dollar amount of additional term you should buy. Enter $0 if you have no existing policy.

What This Calculator Does

The Life Insurance Needs Calculator answers the question every working parent has but almost no one runs the math on: how much life insurance do I actually need, and how short is my current policy? Drop your income, dependents, mortgage balance, planned education funding, savings, spouse income, and target replacement years. The calculator returns the recommended coverage today using the industry-standard DIME framework (Debts + Income + Mortgage + Education) net of liquid assets and your spouse’s continuing earnings, the gap vs. any existing policy you have, the coverage as a multiple of income, and a 20-year term-life premium estimate so you know roughly what the right amount of coverage costs.

Most online life-insurance calculators use the “buy 10× your income” rule of thumb. That rule is right for the median single-earner working parent and wrong for many edge cases — two-earner families need less because the surviving spouse covers part of the load, single parents with toddlers need more, retirees with grown kids often need none. The DIME framework captures the actual dollar exposures rather than relying on a heuristic. The output is a concrete coverage number, not an opinion.

The Math — DIME, Then Net

Three legs do most of the work. Income replacementcovers your dependents’ lifestyle until they’re financially independent — annual income × replacement years, typically 15-25 years for parents with school-age kids and 5-10 years for empty-nesters with retirement on the horizon. Mortgage payoff is a lump-sum benefit so survivors keep the home without monthly principal-and- interest pressure during what is already the worst year of their lives. Education fundingcovers your dependents’ post-secondary education at today’s sticker price ($110K in-state public, $180K out-of-state, $320K private — CollegeBoard 2025).

Two offsets keep the math honest. Spouse incomereduces the income-replacement leg because if your spouse continues to work, that income covers part of the household’s ongoing needs. Liquid savingsdirectly offset the coverage need — a $1M gross need shrinks to $700K if you’ve already saved $300K. The net need is what actually has to come from the policy. Subtract any existing coverage, and you have the dollar amount of additional term to buy.

A Worked Example — Two-earner family with two kids

Income $120K, spouse income $80K, two dependents, education funding $120K each, mortgage $350K, final expenses $20K, liquid savings $150K, replacement years 20, existing policy $500K:

Income replacement: $120K × 20 = $2.4M
Spouse offset: $80K × 20 = −$1.6M
Mortgage payoff: $350K
Education funding: $120K × 2 = $240K
Final expenses: $20K
Liquid savings: −$150K
Net need: $1.26M
Existing policy: $500K → gap $760K additional term to buy
Coverage as multiple of income: 10.5× — within the standard 10-15× guidance band
Estimated 20-yr term premium for the additional $760K: ~$380/yr ($32/mo) for a healthy 35-yr-old non-smoker

The verdict line says “$760K coverage gap.” The action implied: buy $750K of 20-yr term to layer on top of the existing $500K. Total monthly premium across both policies stays under $50 for the typical healthy 35-yr-old non-smoker.

When This Is Useful

Six high-value moments. First child arriving soon. The first life-insurance purchase most people make. Run the calc with replacement years = 25 to cover until the child finishes college. Buy term + the right beneficiary structure before the baby is here. Mortgage refinance or new home purchase. Mortgage balance is the largest discrete leg of DIME for most working families. If you just refinanced from $200K to $450K, your insurance need just jumped $250K. Re-run the calc the same week. Dependent changes. New child = more coverage; child finishes college = less coverage. Income jumps. A 50 % raise often triggers a lifestyle inflation that increases the replacement need. Run the calc 6 months after each major comp event. Job change. Employer group life ends with employment — re-run the calc treating the group portion as gone, and buy enough individual term to cover the full gap. Approaching the empty nest. The DIME need typically peaks when youngest dependent is 5-10 and declines steadily after that — most 50-somethings need substantially less coverage than they did at 35. Skipping this re-run leads to over-insured retirees paying $200/mo for coverage whose need ended a decade ago.

Common Mistakes

Trusting the “10× income” rule of thumb.It’s right for the median single-earner working parent and wrong for many edge cases. Two-earner families with school-age kids and a paid-off house need 5-7×. Single earners with toddlers, a $400K mortgage, and a stay-at-home spouse need 12-18×. Retirees with adequate savings need 0-2×. Run DIME, not the heuristic.
Forgetting to insure a stay-at-home spouse.Replacing childcare, household management, and logistics costs $40-60K/yr in markets like SF / NY / DC. A stay-at-home spouse’s economic value is real. Run the calculator twice — once with each adult as the insured — and size both policies to the household’s actual needs.
Counting employer group life as permanent.Group life ends when employment ends. The typical 1-2× salary group benefit is meaningful for a $200K earner ($200-400K of coverage), but it disappears the day you change jobs, get laid off, or retire. If your job change is plausible inside the next 5 years, treat the group portion as a temporary supplement and buy individual term as if it didn’t exist.
Buying whole life when term is the right structure. Whole life bundles a savings vehicle into the premium at industry-mediocre returns and 5-10× the cost of equivalent term coverage. The only situations where whole life makes financial sense are estate-tax planning at the $13M+ exemption level and special-needs trust funding. For 95 % of households, the right structure is term life sized to DIME + invested savings outside the policy.
Locking in a 30-yr term when the need taper is obvious. Laddering — buying multiple term policies with different end dates — saves 15-25 % on total premium when your need clearly drops at predictable milestones (kids out of college, mortgage paid off). Example: $750K of 30-yr term + $250K of 15-yr term beats $1M of 30-yr term outright on cost. Worth structuring above $750K of need with a clear taper schedule.
Including illiquid assets in the savings-credit field.The credit only counts assets your survivors can actually access in the first 30-90 days. Home equity is illiquid (selling takes months). Business equity is illiquid and often tied to your active management. Retirement accounts owned solely by your spouse don’t belong in your policy’s savings credit — they’re already in spouse’s side of the math. Use only joint checking + brokerage + retirement accounts in your name.

After sizing the death-benefit need, confirm the survival case is also funded — pair this calc with the Retirement Savings Calculator to verify your savings are on track for the same dependents if you live to 90. The savings-credit input pulls directly from liquid net worth, so run the Net Worth Calculator first to get an honest number for the offset. The mortgage leg uses your current principal balance — if you are considering a refi, the Mortgage Calculator models the new principal against the insurance need before you lock the rate. And because year-end tax savings boost next year’s liquid savings credit, the Tax-Loss Harvesting Calculator is the natural December companion to this one.

Frequently Asked Questions

The most common questions we get about this calculator — each answer is kept under 60 words so you can scan.

What is the DIME method and is it the right framework?
DIME stands for Debts + Income + Mortgage + Education — the four legs of need that life insurance addresses for a working parent. It’s the framework every fee-only fiduciary planner uses because it captures the actual dollar exposures rather than relying on the ‘10× income’ rule of thumb that misleads two-earner households (which need less because the surviving spouse’s income covers part of the load) and empty-nesters (who often need very little because savings handle the residual). The calculator runs the full DIME math, nets out spouse income and existing savings, and then surfaces the gap vs. your current policy. The output is the dollar amount of additional term coverage to buy — concrete, not an opinion.
Why does the calculator subtract spouse income?
Because if your spouse continues to work after your death, that income covers part of the household’s ongoing needs — and a policy that ignores it would over-insure you. A single-earner family needs to replace 100 % of the deceased’s income to maintain lifestyle. A two-earner family where the deceased made 60 % of household income only needs to replace the 60 % delta, not 100 %. The calculator multiplies spouse income by your replacement-years target and subtracts it from the gross need. Set spouse income to $0 if you’re the only earner or if your spouse plans to stop working after the loss.
What about the ‘10× annual income’ rule of thumb?
It’s a heuristic that’s right for the median single-earner working parent and wrong for many edge cases. A two-earner family with school-age kids and a paid-off house probably needs 5-7×. A single earner with toddlers, a $400K mortgage, and a stay-at-home spouse needs 12-18×. A retiree with grown kids and adequate savings needs 0-2×. The rule produces wildly off coverage in either direction at the tails. The DIME-method calculator gives you the actual number; the calculator also surfaces the multiple-of-income figure so you can sanity-check it against the heuristic.
Should I buy term or whole life?
Term, almost always, for the protection function. Term life buys $X of death benefit for $Y per year for a fixed window (10/15/20/30 years) at a fraction of the cost of permanent insurance — a healthy 35-yr-old non-smoker pays roughly $25-40/mo for $1M of 20-yr term.

Conservative — calibrated for a healthy non-smoker in their 30s buying 20-yr term. The midpoint is $0.50 per $1,000 of coverage per year. A 35-yr-old non-smoker buying $1M of 20-yr term typically pays $480-650/yr (varies by state, carrier, exact health profile). Smokers pay 2-3× more. Age 50 buys at 3-4× the 35-yr rate.

Does my employer’s group life count?
Yes, but with a major caveat: it ends when employment ends. The typical group life policy is 1-2× salary — meaningful for a $200K earner (so $200-400K of coverage), but it disappears the day you change jobs, get laid off, or retire. The calculator’s ‘existing policy’ field includes employer group life, but if your job change is plausible inside the next 5 years, treat the group portion as a temporary supplement and buy enough individual term to cover the full gap if it disappeared tomorrow. Job-stable + same-employer-for-decades workers can include group life; everyone else should buy as if it doesn’t exist.
What about the spouse’s coverage?
Run the calculator twice — once with you as the insured, once with your spouse. Each policy sized to its own DIME math. Two-earner couples often discover the lower earner needs more coverage than they expected, because eliminating the lower income still leaves the family with a real shortfall against fixed obligations (mortgage, education funding, savings rate). Stay-at-home spouses absolutely need coverage — replacing childcare, household management, and logistics costs $40-60K/yr in markets like SF/NY/DC, and life-insurance proxies for that obligation. Don’t skip insuring a non-working spouse on the assumption that they’ll ‘just keep doing what they’re doing.’
How does this interact with estate-tax planning?
For 99 % of families, it doesn’t — the federal estate-tax exemption is $13.6M per person ($27.2M per couple) in 2026 and rising. Below that, life-insurance proceeds pass tax-free to named beneficiaries and there’s no estate-tax angle. Above the exemption, ILIT (irrevocable life insurance trust) structures keep the death benefit out of the taxable estate.

If you want to be more conservative, multiply your education-cost input by 1.3 to account for 7 years of college-cost inflation between now and a 5-yr-old’s freshman year.
What if my income is uneven (commission, freelance, business owner)?
Use a 3-year average of net business income. Insurance carriers underwrite based on documented earnings, and they’ll pull your last two tax returns; if your 2024 was $80K and 2025 was $250K, they’ll likely use ~$165K as the underwriting income — and that’s the right number for the calculator too. Don’t enter your peak year (over-insures during a slow year, blows premium budget) or your trough (under-insures during a peak year). For S-corp owners, use net business income + W-2 — the combined figure that flows to your 1040.
How often should I re-run the calculator?
Major life events: marriage, divorce, new child, mortgage refi or payoff, large income change, dependent leaving the nest. Routine check-ins: every 5 years between major events. The DIME need typically peaks when youngest dependent is 5-10 years old and declines steadily after that — most 50-somethings need substantially less coverage than their 35-yr-old selves did. Re-running on the cadence above prevents two failure modes: paying premiums on coverage you no longer need (over-insured retiree paying $200/mo for a policy whose need ended 10 years ago) and being under-insured during the peak family-formation years.
