DIME adds four numbers: Debt, Income replacement, Mortgage, and Education. Total them, then subtract what you already have — group coverage, liquid savings, and Social Security survivor benefits. The remainder is your coverage gap, rounded up to a real policy size. It beats a multiple-of-income rule because it prices your obligations, not your paycheck.
Why does every life insurance calculator give you a different number?
Because they're answering different questions. One is sizing your paycheck, one is sizing your debts, one is sizing your whole earning life. All three are defensible. None of them agree, so you close the tab and the $50,000 policy through work stays the only thing standing between your family and the mortgage.
The version of this we hear most often sounds like: "I make $85,000 and I've got a $50,000 policy through work. If I died tomorrow my wife would have to sell the house inside a year. I've known that for three years. Every time I look it up I get forty tabs of contradictory advice and a guy calling me."
That's not a knowledge problem. It's a decision-paralysis problem, and it has a specific cause: nobody explains the mechanism behind the number, so every calculator feels equally arbitrary. This guide explains one mechanism — DIME — in enough detail that you can build the number yourself on a napkin, then defend it.
The scale of the stall is measurable. LIMRA and Life Happens put U.S. adult life insurance ownership at 51% in their 2025 Insurance Barometer Study, with a total need-gap of 40% of adults — close to 100 million people who own none or not enough. The same study found adults aged 18 to 30 overestimate the cost of a $250,000 20-year level term policy by 10 to 12 times.
Group coverage is a default, not a decision. It's usually a flat amount or one to two times salary, it ends the day the job ends, and it makes the box feel checked when it isn't.
What is the DIME method, exactly?
DIME is an addition problem with four terms — Debt, Income, Mortgage, Education — followed by one subtraction. You add up the obligations your income currently carries, then subtract the resources that would still be there without you. What's left is the face amount you're short.
The reason it works better than "ten times your salary" is that it prices your balance sheet. Two people earning $85,000 in Fort Wayne can be $900,000 apart on need: one rents with no kids, the other has a $228,000 mortgage and a four-year-old. A multiple of income cannot see that difference. DIME can.
The reason it's imperfect is that it's a straight sum with no discounting, no inflation, and no memory of what you already own. We'll get to all three. First, the four letters.
| Letter | What belongs in it | The common mistake |
|---|---|---|
| D — Debt | Every non-mortgage balance your family would still owe: car loans, credit cards, personal loans, co-signed or private student loans that don't discharge at death, plus a final-expense and cash cushion figure you choose yourself. | Putting the mortgage here as well as under M. That double-counts the single biggest line and can inflate the answer by six figures. |
| I — Income | Annual income multiplied by the number of years the household needs it — usually until the youngest child is financially independent. | Using gross pay. The family never spent gross pay. Payroll and state tax come out first. |
| M — Mortgage | The current payoff balance on the home. One number, from the most recent statement. | Using the original loan amount or the home's market value instead of the remaining principal. |
| E — Education | Projected tuition, fees, room and board per child, times the number of children you intend to fund. | Assuming a private-school price for a family that will realistically use an in-state public university — or ignoring that costs rise between now and freshman year. |
How do you fill in each letter without double-counting?
Work from statements, not memory, and give every dollar exactly one home. The mortgage lives under M and nowhere else. The car loan lives under D. If a debt is secured by the house, it belongs to M. If it would follow your family regardless, it belongs to D.
Debt. Pull the current payoff figure for each balance, not the monthly payment. Federal student loans in the borrower's own name are discharged at death, but a co-signed private loan generally is not — that one survives you and belongs in D. Add your own final-expense number. There's no national figure you should borrow here; pick an amount your family would actually want in the bank and label it as an assumption.
Income. Multiply annual income by the number of years the household still needs it. The usual stopping point is the year your youngest turns 18. Do not zero out a parent who isn't paid. The U.S. Department of Labor's National Database of Childcare Prices reported a median of $10,194 a year for infant center-based care in medium-sized counties in 2018, which the Women's Bureau restated as $11,354 in 2022 dollars. Allen County had 402,329 residents in the Census Bureau's 2025 estimate, which puts it squarely in that medium band. That's one line item of one child's care, and it's real money the surviving parent has to find.
Mortgage. One number: the payoff balance. Nationally, households and nonprofits owed $13.85 trillion on one-to-four-family residential mortgages in the first quarter of 2026, per the Federal Reserve's Z.1 Financial Accounts. Balances amortize slowly at current rates — Freddie Mac's Primary Mortgage Market Survey put the 30-year fixed average at 6.66% for the week ending July 30, 2026 — so most of an early payment is interest and the M line barely moves for years.
Education. The National Center for Education Statistics puts average in-state tuition and required fees at Indiana public four-year institutions at $9,886 for 2022–23, and $21,016 once room and board are included. Four years of that is $84,064 per child at 2022–23 prices. Multiply by the number of children. Then decide, out loud, whether you're funding all four years or half of it.
Give every dollar exactly one home. The mortgage lives under M and nowhere else.
What does DIME look like with real numbers?
Here's the whole calculation for one household, with the arithmetic shown. Marcus and Dana Reeves live in Fort Wayne. Marcus is 38 and earns $85,000. Dana is 36 and earns $34,000 part-time. Their kids are Ella, 9, and Ben, 4. Marcus's employer provides a flat $50,000 of group life. That's the setup from the top of this guide, with numbers attached.
Their house is worth roughly what Allen County houses are worth — Realtor.com's median listing price for the county, published on FRED, was $327,450 in June 2026 — and they owe $228,000 at 6.25% with 22 years to run. Their non-mortgage debt is a $17,400 car loan, $4,800 in cards, and a $9,000 private student loan Marcus co-signed for Dana. They chose $12,000 as their final-expense and cash-cushion figure.
Income replacement runs 14 years, until Ben turns 18. Education is two children at the Indiana public four-year figure. Everything else is a subtraction.
| Line | Arithmetic | Amount |
|---|---|---|
| D — Debt | $17,400 car + $4,800 cards + $9,000 co-signed loan + $12,000 final expenses | $43,200 |
| I — Income | $85,000 × 14 years until Ben turns 18 | $1,190,000 |
| M — Mortgage | Current payoff balance | $228,000 |
| E — Education | $21,016 × 4 years × 2 children (NCES, Indiana public 4-year, 2022–23) | $168,128 |
| DIME total | 43,200 + 1,190,000 + 228,000 + 168,128 | $1,629,328 |
| Less group life | Employer-provided flat benefit | −$50,000 |
| Less liquid savings | Emergency fund plus taxable brokerage earmarked for the family | −$46,000 |
| Less Social Security | Children's survivor benefits, calculated in the next section | −$326,000 |
| Coverage gap | 1,629,328 − 422,000 | $1,207,328 |
| Face amount purchased | Rounded up to a policy size carriers actually issue | $1,250,000 |
Insurance and annuity guarantees are backed by the claims-paying ability of the issuing carrier. Products are not FDIC-insured, not bank guaranteed, and may lose value.
What does Social Security actually pay a surviving family?
A percentage of the deceased worker's basic benefit amount, capped for the household as a whole. Social Security's own publication is specific: a surviving spouse at full retirement age generally gets 100%, a surviving spouse aged 60 to full retirement age gets between 71% and 99%, a surviving spouse of any age caring for a child under 16 gets 75%, and each child gets 75%.
Then the ceiling. SSA Publication 05-10084 (April 2026) states the family maximum "varies between 150% and 180% of the deceased worker's benefit amount." Three people at 75% each would come to 225%, so the cap bites in most families with two or more children. There's also a one-time lump-sum death payment of $255, which is not a rounding error you should plan around.
Children's benefits run to age 18, or 19 if they're still in secondary school full time. The surviving spouse's caregiver benefit stops when the youngest child turns 16 — the gap between that and the spouse's own retirement eligibility is the reason people call it the blackout period.
For the Reeves arithmetic we used SSA's published national averages from the Monthly Statistical Snapshot for June 2026: $1,180.50 a month for children of deceased workers and $1,377.41 for widowed mothers and fathers. Ella has 9 years of eligibility left and Ben has 14. That's $1,180.50 × 12 × 9 = $127,494 for Ella and $1,180.50 × 12 × 14 = $198,324 for Ben, or $325,818 together. Round to $326,000.
Dana's own caregiver benefit — $1,377.41 × 12 × 12 = $198,347 over the twelve years until Ben turns 16 — we deliberately left out of the offset. Here's why. The three checks un-capped come to $3,738.41 a month, and for the 180% family maximum to cover that, Marcus's own basic benefit would have to be at least $2,076.89. It may not be. Leaving Dana's stream out absorbs the haircut instead of guessing at it.
The caveat that matters more than any of this: your family's number depends on your earnings record, not on a national average. Pull the actual survivors estimate off your my Social Security statement — SSA puts it there — and use that instead of ours. How claiming age works is a separate question, but the same statement answers both.
Three people at 75% each comes to 225%. The family maximum stops at 180%. Somebody's check gets trimmed.
Where does DIME overstate the number?
In three places, and they're all in the I. DIME multiplies gross income by years, assumes the money sits in a checking account earning nothing, and ignores the surviving spouse's own paycheck. Each one pushes the answer up.
Gross versus spendable. Marcus's $85,000 was never $85,000 in the house. Indiana's state adjusted gross income tax rate is 2.95% for 2026 and Allen County adds 1.59%, per the Indiana Department of Revenue's Departmental Notice #1 effective January 1, 2026. Social Security and Medicare payroll tax takes another 7.65% from the employee side, per SSA's own rate table, on earnings up to the 2026 taxable maximum of $184,500. That's $3,859 plus $6,502.50, or $10,361.50 a year — $145,061 across 14 years, before a single dollar of federal income tax. The honest I line is closer to $1,045,000 than $1,190,000. Federal brackets stack on top of that; we walk through those in the 2026 federal tax brackets.
No investment return. A $1.2 million death benefit doesn't sit still for fourteen years. Some of it gets invested and some of it earns something. DIME's flat multiplication quietly assumes a 0% return, which overstates what you need to hand over on day one.
The surviving spouse's income. Dana earns $34,000. DIME doesn't know that. A full needs analysis nets her earnings against the household's spending before capitalizing the shortfall, and that alone can move the answer by several hundred thousand dollars.
And the double-count. The most common DIME error we see isn't philosophical. It's arithmetic: the mortgage balance entered under D and under M. On the Reeves numbers that single mistake would have added $228,000 to a $1.6 million answer. If you'd rather see this with your own numbers in it, run it through the calculators before you talk to anyone.
Where does DIME understate it?
Wherever a price rises or a household loses a second pair of hands. DIME is a snapshot in today's dollars, which is fine for the mortgage and wrong for tuition, childcare, and the cost of living fourteen years from now.
The education line is the clearest case. The $21,016 figure is the NCES average for Indiana public four-year institutions in 2022–23. Ben starts college in 2040. Using a 2022–23 price for a 2040 bill is a known understatement, and DIME has no built-in mechanism to fix it. You either inflate the line yourself or accept that E is a floor.
Household running costs are the second gap. The Bureau of Labor Statistics put average annual expenditures per consumer unit at $78,535 in its 2024 Consumer Expenditure Survey — housing alone $26,266, transportation $13,318, food $10,169, healthcare $6,197. Those don't halve when one earner is gone. The mortgage payment is identical, the insurance is identical, and the grocery bill goes down by a fraction, not a half.
The third gap is the one nobody puts on a worksheet: a surviving parent may not be able to work the same hours. If Dana drops to part-time to cover what Marcus used to cover, the household loses income the model never counted. That's a judgment call, not a formula — and it's the single biggest reason to sanity-check DIME against a second method.
An educational estimate for the 2026 plan year — not a quote, an offer, or a guarantee of any rate, return, or approval.
How does DIME compare to '10× income' and to human life value?
The three methods answer three different questions, and their answers separate by roughly a factor of two on the same household. Multiple-of-income prices your paycheck. DIME prices your obligations. Human life value prices your entire remaining career.
On the Reeves numbers, 10× income gives $850,000. It takes eleven seconds and it's not a bad first sanity check. What it can't do is tell you why. It's the same answer for a renter with no children as for a family with a $228,000 mortgage and two kids to put through school, and that's a real limitation, not a nitpick.
DIME gives $1,629,328 gross, $1,207,328 after offsets. It's traceable line by line, which means you can argue with it. That's the whole point — a number you can argue with is a number you'll actually buy.
Human life value starts from the other end: what is the rest of your working life worth to the people who depend on it? Marcus has 27 years to age 65. On a spendable basis of $74,638.50 a year after Indiana, Allen County, and payroll tax, that's $2,015,240 undiscounted — before federal income tax, before subtracting what Marcus consumes himself, and before discounting to present value. A proper HLV calculation applies all three of those and lands lower, but it starts high, which is why HLV is the method that most often produces a number people won't buy.
Needs analysis is the professional version and the most accurate of the four: it projects the household's actual spending year by year, nets the survivor's income and Social Security against it, discounts the shortfall, and subtracts existing assets. It's also the one you cannot do on a napkin. DIME exists because it gets you 80% of the way there in five minutes. We keep a plain-English glossary if a term here is new.
- Multiple of income (10×): $850,000 — fast, ignores everything specific to you.
- DIME, gross: $1,629,328 — obligation-priced, no offsets applied.
- DIME, net of coverage, savings and survivor benefits: $1,207,328 — what the Reeveses actually bought against.
- Human life value, undiscounted spendable earnings to 65: $2,015,240 — the ceiling, not the recommendation.
Why does the number shrink every single year?
Because three of the four DIME components are on a countdown. The income line loses a year every year. The mortgage amortizes. Tuition gets paid and stops being a liability. Only the debt line is roughly flat, and that's the smallest one.
This is not a footnote. It's the reason a single 30-year policy for the full amount is the wrong shape for most families. Hold Marcus's income flat at $85,000, run the mortgage down its own amortization schedule, and retire each child's tuition as it's spent, and the Reeves DIME total falls 87% over fourteen years.
| Ben's age | D — Debt | I — Income | M — Mortgage | E — Education | DIME total |
|---|---|---|---|---|---|
| 4 (today) | $43,200 | $1,190,000 | $228,000 | $168,128 | $1,629,328 |
| 8 | $21,000 | $850,000 | $206,000 | $168,128 | $1,245,128 |
| 12 | $12,000 | $510,000 | $178,000 | $168,128 | $868,128 |
| 16 | $12,000 | $170,000 | $142,000 | $105,080 | $429,080 |
| 18 | $12,000 | $0 | $120,000 | $84,064 | $216,064 |
Buying one flat amount for thirty years means paying for coverage you'll stop needing in year eleven.
Does laddering two or three terms really cost less?
Yes, and the mechanism is mortality, not marketing. The cost of insuring a life rises steeply with age. A level premium is just that rising cost averaged across the whole term and charged flat. Stretch the term further into the expensive years and the average — and therefore the premium — goes up.
You can watch this happen in a rate table the federal government publishes. The Office of Personnel Management's FEGLI Option B rates, in effect since the first pay period on or after October 1, 2021, charge $0.043 per $1,000 per month at ages 35–39 and $0.867 at ages 60–64. Same coverage, same program, 20 times the price. Translated into a round number, that's what the chart below shows.
Now run Marcus's ladder against that curve. Average the OPM rate across each term he'd start at 38 and you get $0.0801 per $1,000 per month over 10 years, $0.1658 over 20 years, and $0.3850 over 30 years. The 30-year blend is 4.8 times the 10-year blend, because it has to pre-fund the 60-to-64 band where the rate is $0.867.
One policy: $1,250,000 for 30 years at the 30-year blend is 1,250 × $0.3850 = $481.29 a month.
Three policies: $650,000 for 10 years (650 × $0.0801 = $52.07) plus $350,000 for 20 years (350 × $0.1658 = $58.03) plus $250,000 for 30 years (250 × $0.3850 = $96.26). Total $206.36 a month.
That's $274.93 a month, or $3,299 a year, for the same $1,250,000 of day-one coverage. And here's the catch, said plainly: the ladder isn't a discount. It's buying less insurance later on purpose. In year 11 the Reeveses drop to $600,000 and in year 21 to $250,000, because by then Ben is 24 and the mortgage is nearly gone. If the need doesn't actually shrink — a special-needs child, a business loan, an estate with an illiquid asset in it — the ladder is the wrong structure and the flat 30-year policy is the right one.
Two structural notes. The OPM figures above are a published age-banded group rate schedule, used here to show how the cost curve works; they are not a term life quote, and real level-term pricing adds carrier expense, profit, and your own underwriting class. And every ladder rung should be convertible — the option to turn term into permanent coverage without a new medical exam is what protects you if your health changes mid-ladder. We cover that in converting term to permanent.
| Structure | Blended rate per $1,000/month | Face amount | Monthly cost |
|---|---|---|---|
| Single 30-year policy | $0.3850 | $1,250,000 | $481.29 |
| Ladder rung 1 — 10-year term | $0.0801 | $650,000 | $52.07 |
| Ladder rung 2 — 20-year term | $0.1658 | $350,000 | $58.03 |
| Ladder rung 3 — 30-year term | $0.3850 | $250,000 | $96.26 |
| Ladder total | — | $1,250,000 | $206.36 |
| Difference | — | Same day-one coverage | −$274.93 (−$3,299/yr) |
What do you do with the number once you have it?
Pick the term lengths off the countdown, not off a price list. Then shop it, because underwriting classes for identical health differ by carrier, and the same applicant can land two classes apart at two companies. That spread is usually worth more than the difference between one carrier's rate and another's.
Match each rung to the obligation it retires. The mortgage rung ends when the mortgage does. The income rung ends when the youngest is independent. The education rung ends with the last tuition bill. If you're sizing coverage specifically around the house and the paycheck, the mortgage and income protection guide goes deeper on term length. If you're still deciding what kind of policy to buy, start with term vs. whole vs. IUL — DIME sizes the number, it doesn't pick the product.
Then check the thing DIME can't see. This is where the four pillars stop being separate. Marcus's $1,250,000 death benefit is, under IRS Publication 525 for 2025, generally not included in his beneficiary's gross income — the proceeds arrive whole. Indiana repealed its inheritance tax, and the Department of Revenue confirms no Indiana inheritance tax is owed for deaths after December 31, 2012. So far, so good. But if the Reeveses had a commercial loan on a rental property, a term policy expiring in year 10 against a balloon due in year 12 would leave Dana refinancing a note in the worst month of her life. That's a debt-structure question and an insurance question at the same time, and it only gets caught if someone is looking at both. If your situation has more than one moving part, that's the conversation to have.
Last, re-run the number when the facts change — a birth, a move, a refinance, a raise, a divorce. And re-read your beneficiary designations while you're in there, because the designation on the policy overrides whatever the will says. Indiana probate and creditor rules are state-specific; confirm yours with your own attorney rather than a national article.
If a carrier or an agent gives you trouble, the Indiana Department of Insurance licenses producers and companies in this state and takes consumer complaints. That's the regulator, and using it costs nothing.

Frequently asked questions
What does DIME stand for in life insurance?
Debt, Income, Mortgage, Education. You add your non-mortgage debts plus a final-expense figure, your annual income times the years your family needs it, your remaining mortgage balance, and projected education costs per child. Then you subtract existing coverage, liquid savings, and expected Social Security survivor benefits. The remainder is the face amount you're short.
Should the mortgage go under D for debt or M for mortgage?
M, and only M. Entering it in both places is the most common DIME error and it inflates the answer by the full balance. In the worked example in this guide, that mistake would have added $228,000 to a $1.6 million total. D is for debts your family would still owe that aren't secured by the home.
Do Social Security survivor benefits reduce how much life insurance I need?
Yes, and they should be subtracted. Per SSA Publication 05-10084 (April 2026), each child gets 75% of the worker's basic benefit amount, and a surviving spouse caring for a child under 16 also gets 75%. The household total is capped by the family maximum, which SSA states varies between 150% and 180% of the worker's benefit. The actual dollar amount depends entirely on your earnings record, so pull the survivors estimate from your my Social Security statement rather than using an average.
Is DIME better than the 10-times-income rule?
It's more specific, which usually means more accurate. On the household in this guide, 10× income gives $850,000 and DIME gives $1,207,328 after offsets — a $357,000 difference driven by a $228,000 mortgage and two children's education. A multiple of income can't see either. Use 10× as a sanity check on DIME, not as a substitute for it.
Why does laddering multiple term policies cost less than one big 30-year policy?
Because the cost of insuring a life climbs sharply with age and a level premium averages that climb across the whole term. Using the federal FEGLI Option B rate schedule as the cost curve, the blended rate for a 38-year-old is $0.0801 per $1,000 per month over 10 years but $0.3850 over 30 years. A $650,000 / $350,000 / $250,000 ladder prices out at $206.36 a month against $481.29 for a single $1,250,000 30-year policy. The trade-off is real: you're deliberately holding less coverage in the later years.
Does DIME account for my spouse's income or our existing assets?
No, and that's its biggest weakness. DIME has no line for the surviving spouse's earnings, no line for retirement or investment accounts, and no assumption that the death benefit earns anything once invested. All three push the DIME answer higher than a full needs analysis would. Subtract liquid savings you'd genuinely spend on the family, and treat DIME's total as an upper bound to argue down.
Is a life insurance death benefit taxable?
Life insurance proceeds paid by reason of the insured's death are generally not included in the beneficiary's gross income, per IRS Publication 525 for 2025. Interest paid on proceeds held by the carrier can be taxable, and estate treatment is a separate question from income treatment. Indiana repealed its inheritance tax and the Department of Revenue confirms none is owed for deaths after December 31, 2012. This is educational content only, not tax or legal advice — consult your own CPA or attorney before acting.
