$82K Salary, $375K Mortgage, Two Kids Under 8: How the DIME Method Reveals a $1.5M Coverage Need — and the $1.23M Gap Your Employer Policy Won't Fill
The Coverage Assumption That Could Leave Your Family Shorthanded
Marcus and Priya, both 35, just settled into their second home. They have two kids — Lily, age 6, and James, age 3. Marcus earns $82,000 a year as a project manager. His employer provides a group life insurance policy worth 2× his salary: $164,000. Three years ago, he also bought a $100,000 term policy online in about 15 minutes because it seemed like a reasonable thing to do at the time.
So Marcus figures he's covered. $264,000 in total life insurance. That's something, right?
Here's the number that keeps honest financial planners up at night: $264,000 would last Marcus's family approximately 3.2 years at their current lifestyle. Then Priya is on her own — with a $375,000 mortgage, two kids heading toward college, and an income gap of $82,000 per year to fill.
This isn't fear-mongering. It's arithmetic. And the math has a name: the DIME method.
What the DIME Method Actually Is (And Why It Beats the 10× Income Rule)
You've probably seen "multiply your salary by 10" framed as a coverage rule of thumb. It's easy to remember, and it's regularly wrong — sometimes by hundreds of thousands of dollars in either direction.
The DIME method is more precise because it accounts for the actual financial obligations your family carries, not a generic multiplier applied to everyone the same way. DIME stands for:
- D — Debt (everything you owe, excluding the mortgage)
- I — Income replacement (what your family needs annually, for how long)
- M — Mortgage (your current outstanding balance)
- E — Education (estimated college costs for each child)
Add those four numbers. Subtract existing coverage. What's left is your true gap.
For a detailed walkthrough of how this formula applies across different income levels and household structures, the post $95K Salary, $380K Mortgage, Two Kids: How the DIME Method Calculates Your $1.5M Life Insurance Need shows the same framework applied to a slightly different family.
Marcus's DIME Calculation: The Full Breakdown
D — Debt (Excluding Mortgage): $27,000
Marcus has a car loan with $18,000 remaining and about $9,000 spread across two credit cards. If he's gone tomorrow, these debts don't vanish — they come directly out of whatever assets the family has left.
Debt total: $27,000
I — Income Replacement: ~$959,000
This is the largest component and the most important one to get right.
James is 3 years old. He'll need meaningful financial support until he's roughly 21 — that's 18 years of income replacement. Rather than simply multiplying $82,000 × 18 (which produces $1,476,000 in nominal dollars and overstates the lump sum needed today), we calculate the present value: the single amount Priya would need to invest today, earning 5% annually, to replace $82,000 per year for 18 years.
The present value annuity factor for 18 years at 5% works out to approximately 11.69 — that is, 1 minus 1.05 to the negative 18th power, divided by 0.05.
$82,000 × 11.69 = $958,580 (roughly $959,000)
This is the lump sum needed at the time of death to fund 18 years of Marcus's income in today's purchasing power.
Income replacement total: ~$959,000
One important note on the "I" calculation: the accuracy of your income figure matters enormously here. A recent federal fraud case in Massachusetts highlighted exactly how much damage results when income gets misrepresented — an employer there systematically hid payroll to reduce costs, and the downstream distortions were significant. The same principle applies to your coverage math: if your income is variable, if you're a contractor or small business owner, or if last year was unusually high or low, use a three-year average rather than a single-year snapshot. An income error in the DIME formula cascades directly into a six-figure coverage miscalculation.
M — Mortgage: $375,000
The outstanding mortgage balance goes here in full. The goal is to ensure Priya isn't forced to sell the family home or struggle with a payment she can't service on her income alone.
Mortgage total: $375,000
E — Education: $130,000
Two kids. College Board data puts the current average total cost — tuition, fees, room and board — at a four-year public university at roughly $28,000 to $35,000 per academic year, growing at approximately 3% annually. For two children at 2026 pricing, budgeting $65,000 each for a four-year in-state public university is a conservative, grounded estimate.
Education total: $130,000
The Final Tally
| DIME Component | Amount |
|---|---|
| D — Debt (non-mortgage) | $27,000 |
| I — Income replacement (18 yrs, 5% discount) | $959,000 |
| M — Mortgage | $375,000 |
| E — Education (2 kids, public university) | $130,000 |
| Gross Coverage Need | $1,491,000 |
| Less: Employer Group Life (2× salary) | ($164,000) |
| Less: Existing Personal Term Policy | ($100,000) |
| True Gap | $1,227,000 |
Marcus has roughly $1.5 million in coverage need and $264,000 in actual coverage. The gap is $1.23 million.
This is exactly the kind of side-by-side analysis Morivex builds for your specific numbers — so you're not left guessing whether $500K is adequate or $1.5M is overkill for your situation.
Why the 10× Rule Misses This by $670,000
If Marcus used the standard "10× salary" shortcut, he'd calculate a need of $820,000. Subtract $264,000 in existing coverage and he thinks he needs about $556,000 more. That's not terrible advice — but he'd still be underinsured by roughly $670,000 compared to what the DIME method produces.
The 10× rule treats Marcus's situation identically to a renter with no kids and no debt. The DIME method captured his actual mortgage balance, his specific education obligation, and a realistic income replacement window. For families with large mortgages, young children, or meaningful non-mortgage debt, DIME consistently produces a higher — and more accurate — coverage need.
What Closing This Gap Actually Costs Per Month
Here's where the math becomes surprisingly encouraging. A $1.2 million 20-year term policy for a healthy 35-year-old male in a Preferred or Preferred Plus health class currently runs approximately $60–$80 per month.
For comparison: a NerdWallet analysis of streaming service spending found that the average U.S. household pays around $61 per month across their streaming subscriptions combined — and most people can't name that figure without checking a statement. Most households spend more time optimizing their streaming bundles than their life insurance coverage. The practical difference is that a lapsed streaming subscription costs you a month of TV. A $1.2 million coverage gap costs your family the calculation above.
| Policy | Monthly Premium (Healthy 35M) | 20-Year Total Cost |
|---|---|---|
| $500K, 20-year term | ~$30–$35 | ~$7,200–$8,400 |
| $1M, 20-year term | ~$47–$60 | ~$11,280–$14,400 |
| $1.25M, 20-year term | ~$55–$70 | ~$13,200–$16,800 |
The difference between $500K and $1.25M in coverage is roughly $25–$35 per month for someone at Marcus's age and health class. For the protection of a $1.23 million gap, that's a remarkably affordable correction.
The Employer Coverage Trap
Here's what makes Marcus's situation even more precarious: $164,000 of his $264,000 in total coverage is employer-provided group life insurance. The moment Marcus changes jobs, gets laid off, or his company restructures its benefits package, that coverage disappears — and he'd need to requalify for individual coverage at whatever his health looks like at that point.
Group life insurance is a workplace benefit, not a coverage foundation. LIMRA data consistently shows that fewer than 20% of people who lose employer-provided group coverage actually replace it with individual coverage within six months. The coverage simply evaporates at exactly the wrong time — often when someone is in a health transition, between jobs, or financially stressed.
The right approach: run the DIME method assuming employer coverage doesn't exist. If you have it, treat it as a bonus. If it disappears — and on any given Tuesday, it might — your family's financial foundation should not depend on it.

How Your Numbers Shift the Answer
Marcus and Priya's scenario is illustrative, but your DIME calculation will produce a different number based on your specifics. Here's a quick look at how common household profiles translate to coverage needs:
| Scenario | Income | Mortgage | Kids | Approx. DIME Need | Typical Employer Coverage | Approx. Gap |
|---|---|---|---|---|---|---|
| Single earner, 33 | $70K | $300K | 2 (ages 2, 5) | ~$1.2M | $140K | ~$1.06M |
| Dual earner, 37 | $95K | $450K | 2 (ages 4, 7) | ~$1.7M | $190K | ~$1.51M |
| Single parent, 40 | $85K | $340K | 1 (age 8) | ~$1.1M | $170K | ~$0.93M |
| High earner, 38 | $130K | $600K | 3 (ages 2, 5, 8) | ~$2.4M | $260K | ~$2.14M |
The pattern across nearly every scenario: employer coverage fills roughly 10–15% of the DIME need. Your family carries the rest as uninsured financial risk.
When Your Coverage Need Starts Declining — and How to Use That
Here's a planning point most people miss: your DIME need actually decreases every year.
- Your mortgage balance drops with every payment
- Your kids move closer to financial independence
- Your income replacement window shortens
- Your savings accumulate and can supplement coverage needs
That means a single large policy bought today — say, $1.5M for 30 years — will significantly over-cover your family in years 20 through 30, when the mortgage may be retired and your kids are adults. You pay for coverage you no longer need.
The efficient alternative is laddering: structuring two or three policies with staggered term lengths that mirror your declining obligation curve. A combination of a $750K 30-year policy (long-term income protection) alongside a $500K 20-year policy (mortgage and education years) at Marcus's age provides the right coverage now while stepping down naturally as obligations shrink — and it typically costs less than a single large 30-year policy.

Run Your Own DIME Calculation
Marcus's numbers are not your numbers. Your income, mortgage balance, number of children, existing debts, current coverage, and household structure all change the output. The DIME method is a framework — the answer only becomes accurate when you plug in your actual figures.
You can model your specific situation at Morivex. Enter your income, outstanding debts, mortgage balance, number of children, and existing coverage — and see your true coverage gap, the monthly cost to close it at your age and health class, and whether a laddering strategy saves you money versus a single large policy.
The goal isn't maximum coverage. It's the right coverage: enough to ensure that if something happens to you, the people who depend on you are genuinely okay — not just covered for a few years before the math runs out.
Marcus's family deserves better than $264,000 and a plan built on a group policy that could vanish the next time he changes jobs. Chances are, so does yours.
