Figuring out how much life insurance you need usually starts with one rule: multiply your income by 10. For an $85,000 salary, that's $850,000.
That number is widely used. For families with kids and a mortgage, it's frequently $500,000 to $1,000,000 short.
Not because the rule is wrong — because it was built for single earners with minimal dependents. The DIME method was built for everything else.
This guide runs both through the same family's real numbers so you can see exactly where the gap is — and which method fits your life.
TL;DR
- DIME method — Adds up Debt + Income replacement + Mortgage + Education. Almost always gives a higher number because it accounts for what your family actually owes.
- 10x income rule — Multiplies your annual salary by 10. Fast and simple, but often $500,000 to $1,000,000 short for families with kids and a mortgage.
- The gap is real — For a family earning $85,000 with 2 kids and a $280,000 mortgage, DIME recommends $1,800,000. The 10x rule recommends $850,000. That's a $950,000 difference.
- Use DIME if — You have children under 18, a mortgage, or significant non-mortgage debt. DIME accounts for what your family actually owes.
- Use 10x if — You're single, your kids are grown, or you're within 10 years of retirement with minimal debt. The simple multiplier is close enough.

Calculate My Life Insurance Need — FreeDIME vs. Income Replacement at a Glance
Before the math, here's the quick comparison. Same family. Same income. Two methods.
| Method | Formula | Result (Example) | Best For |
|---|---|---|---|
| DIME | Debt + Income × Years + Mortgage + Education | ~$1,800,000 | Families with kids and a mortgage |
| 10x Income | Annual salary × 10 | $850,000 | Single earners, empty nesters |
| 7x Income | Annual salary × 7 | $595,000 | Near retirement, debt nearly paid |
The $950,000 gap between DIME and the 10x rule is not a rounding error. For most families, that gap determines whether they keep the house or don't.
How the DIME Method Works
DIME stands for four costs your family would face if you were gone. Each letter is a type of cost — real money your family would need.
D — Debt and Final Expenses
Every non-mortgage debt still in your name: car loans, credit cards, student loans, and burial costs. A funeral with burial costs about $8,300. Most planners round up to $15,000 to include legal and estate fees.
I — Income Replacement
Your annual salary multiplied by the number of years your family needs financial support. With young children, that's typically 15–20 years. With a working spouse and older kids, it might be 10.
M — Mortgage
The current payoff balance on your home — not your monthly payment. The goal is for your family to own the home free and clear, not just keep making payments for a few more years.
E — Education
The projected cost of college for each child. State schools average $25,000 a year in 2026. That's $100,000 per child for four years. Private school runs $55,000 or more per year.
Formula
DIME Total = Debt + Final Expenses + (Income × Years) + Mortgage + (Children × Education Cost) Coverage Gap = DIME Total − (Savings + Existing Coverage) Recommended = Coverage Gap rounded up to nearest $50,000
Example — Jamie's family ($85,000 income, 2 kids, $280,000 mortgage, $22,000 in other debts): D: $22,000 debt + $15,000 final expenses = $37,000 I: $85,000 × 15 years = $1,275,000 M: $280,000 mortgage payoff E: 2 children × $100,000 = $200,000 ───────────────────────────── DIME Total: $1,792,000 Minus $30,000 existing employer coverage Coverage Gap: $1,762,000 Recommended: $1,800,000
DIME is exact because the costs your family would face are exact. It covers every debt your family owes — which is why the number tends to shock people.
How Income Replacement Works
The income rule skips the line-by-line math. It asks how much your family needs to keep living the same way if your paycheck stops for good.
The 10x Rule
Multiply your annual income by 10. Earn $85,000 — you need $850,000 in coverage. The idea: a lump sum, put in safe investments, can produce income for years. The 10x rule builds in a cushion for that math without requiring a detailed calculation.
The Human Life Value approach asks a different question. It adds up all the money you would earn over your life, then finds what that total is worth in today's dollars. For most people, the result lands close to the 10x rule, which is why the simple multiplier stuck.
Formula
Income Replacement Quick Rules:
10x Rule (standard, most common): $85,000 income × 10 = $850,000
7x Rule (near retirement, minimal debt): $85,000 income × 7 = $595,000
15x Rule (young family, single income, large mortgage): $85,000 income × 15 = $1,275,000
Use 10x as your starting floor. Adjust up or down based on your situation.
The income rule is fast and easy to follow. Its flaw is what it skips: your home loan balance, your kids' college costs, and your other debts. It assumes your family can handle those pieces on their own — which many families cannot.
Side by Side: Same Family, Both Methods
Here is Jamie's full picture — same income, same debts, same house — run through both calculations at once.
| Component | DIME Method | 10x Income | What It Covers |
|---|---|---|---|
| Income replacement | $1,275,000 | $850,000 | 15 years of salary |
| Mortgage payoff | $280,000 | Not included | Keep the house |
| Debt + final expenses | $37,000 | Not included | Car, cards, burial |
| Education (2 kids) | $200,000 | Not included | College fund |
| Total need | $1,792,000 | $850,000 | — |
| Minus existing coverage | −$30,000 | −$30,000 | Employer policy |
| Recommended | $1,800,000 | $820,000 | — |
The 10x rule is not wrong — it just answers a narrower question. It tells you how long your family can replace your paycheck. DIME tells you whether they can pay off the house, eliminate debt, and fund two college educations at the same time.
Who Should Use DIME
Choose DIME if any of these apply to you:
- You have children under 18 who depend on your income
- You carry a mortgage your household couldn't afford on one income alone
- You have significant non-mortgage debt — car loans, credit cards, student loans
- You are the primary or only earner in your household
- You want a number you can trace back to a specific family obligation
DIME gives you a higher number. For families with kids and debt, that higher number is almost always right.
Who Should Use Income Replacement
The 10x rule works well when your situation is simpler:
- You are single with no dependents
- Your children are adults and financially independent
- You are within 10 years of retirement and your mortgage is nearly paid off
- You and your spouse both earn comparable incomes and could maintain your lifestyle independently
- You already carry significant savings that reduce your actual gap
The 10x rule gives you a fast and usable floor. For people near the end of their career with little debt left, that floor is close enough.
The Mental Shortcut: The DIME-First Rule
Formula
The DIME-First Rule:
- Start with 10x your income as your floor
- Then ask three questions: Have a mortgage? → Add the current payoff balance Have kids under 18? → Add $100,000 per child (4 years, public university) Have non-mortgage debt? → Add that balance
If DIME is within 10% of 10x — use 10x. Close enough. If DIME is more than 10% higher — use DIME. The gap is real.
For most families with young children and a mortgage: DIME will be 30–60% higher than 10x income alone.
The DIME-First Rule takes 5 minutes. It shows how far off the simple method falls for your family. For most families with young children and a mortgage, that gap is six figures — worth knowing before you buy.

Both methods have a place. The difference is what each one is designed to answer.
The 10x rule answers: "How much income does my family need to replace?" DIME answers: "How much does my family actually owe and need if I'm gone tomorrow?" For most families with a home loan and young kids, those aren't the same question. The gap between them is what your family would be missing.
Run DIME first. Use 10x as a floor check. If DIME is significantly higher — which it usually is for families — that's the number to insure.
1. Check your employer coverage first
Most employer group policies pay 1–2× your annual salary. Find the exact amount on your benefits portal, then subtract it from your DIME gap. That's the amount you need to buy privately. Treat employer coverage as a supplement — it disappears if you change jobs.
2. Get a term life quote, not whole life
For most people in their 30s and 40s, a 20-year term policy costs well under $100 a month for every $500,000 in coverage. Whole life costs 5–10× more and is rarely the right choice for income protection.
3. Recalculate every 3–5 years
Your mortgage shrinks. Your kids get older. Your income grows. Your coverage need changes. The DIME number you calculate today may be $200,000–$300,000 different from what you need at 50.

Sources & Methodology
The DIME formula on this page calculates: D (non-mortgage debt + final expenses) + I (annual income × income replacement years) + M (mortgage payoff balance) + E (number of children × education cost per child), then subtracts existing savings and current coverage to produce a coverage gap. The result rounds up to the nearest $50,000.
The 102 million American coverage gap figure is from LIMRA's 2024 Insurance Barometer Study. Median funeral cost figures — $8,300 with burial and $6,280 with cremation — are from the NFDA's 2023 General Price List Study, the most recent published survey. Public university cost of $25,000 per year reflects 2026 College Board published averages. Term life insurance premium benchmarks are based on 2024–2025 industry data.
