De Quelle Assurance Vie Ai-Je Besoin ? La Méthode DIME

How Much Life Insurance Do I Need? The DIME Method

Most life insurance guidance leads with a rule of thumb: “buy 10 times your income.” That’s a starting point, not a plan. A $100,000 earner with a $400,000 mortgage, two kids headed to college, and $30,000 in car loans needs different coverage than someone with the same salary, no kids, and a paid-off house.

The DIME method calculates a personalized coverage target based on the four things your income actually needs to cover: Debt, Income replacement, Mortgage, and Education.

The Four Components of DIME

D — Debt

Add up every debt you carry except your mortgage (which has its own component):

• Credit card balances
• Car loans
• Student loans
• Personal loans
• Medical debt

These debts don’t disappear when you die. They become obligations your estate — and potentially your spouse — must handle. Include the full outstanding balances.

I — Income Replacement

How many years of your income does your family need after you’re gone? The standard range is 10-15 years, depending on your family’s situation.

Formula: Annual income x number of years

Subtract any income your surviving spouse would continue earning. If you earn $90,000 and your spouse earns $60,000, and your household needs $100,000/year to maintain its current standard of living, the annual gap is $40,000. Over 15 years, that’s $600,000.

A more precise approach discounts future income to present value. Most people use a simple multiplier as an approximation.

M — Mortgage

Your outstanding mortgage balance. This covers the home outright so your family isn’t forced to sell, take on a second job to make payments, or move under grief.

Use your current payoff balance, not the original loan amount.

E — Education

Project the cost of each child’s education and multiply by the number of children.

College costs in 2026:

School Type	Annual Cost (All-in)	4-Year Total
Public, in-state	$27,000	$108,000
Public, out-of-state	$44,000	$176,000
Private university	$62,000	$248,000

Use a reasonable estimate based on what you’d realistically fund. You don’t have to cover 100% of private school costs — decide what your contribution would be and use that figure.

Running the DIME Calculation

Here’s an example for a 38-year-old with two children (ages 4 and 7):

Component	Amount
Debt (car loan + student loans)	$45,000
Income replacement ($85,000/yr x 15 years, minus spouse’s $55,000 gap x 15)	$450,000
Mortgage balance	$310,000
Education (2 kids x $140,000 each)	$280,000
Total DIME Coverage Target	$1,085,000

Use our life insurance calculator to model your own numbers. Round up to the nearest $250,000 or $500,000 — policy pricing is usually tiered at those increments and the cost difference between $1,000,000 and $1,250,000 in coverage is often small.

How Age and Income Affect Coverage Needs

Coverage targets change across life stages. Here’s how typical DIME totals shift:

Age	Typical DIME Range	Key Driver
25-34	$500,000 - $900,000	New mortgage, young kids, moderate income
35-44	$800,000 - $1,500,000	Peak mortgage + education costs
45-54	$500,000 - $1,000,000	Mortgage declining, kids approaching college
55-64	$200,000 - $600,000	Debts lower, kids independent, spouse’s income more certain

The 35-44 age bracket typically has the highest coverage need. You’re often carrying a large mortgage, supporting young children, and still 20+ years from retirement — creating substantial financial obligations if you were to die.

Term vs Whole Life: Which Should You Buy?

For most families using DIME to calculate coverage, term life insurance is the right product.

Term life covers you for a fixed period (10, 20, or 30 years) at a fixed premium. It’s designed to cover you during your highest-need years and is far less expensive than whole life.

Sample 2026 term life premiums for a healthy non-smoker:

Age	Coverage	20-Year Term Monthly Premium
30	$500,000	$22
30	$1,000,000	$38
40	$500,000	$42
40	$1,000,000	$74
50	$500,000	$110
50	$1,000,000	$195

Whole life covers you permanently and includes a cash value savings component. It costs 10-15 times more than term for the same death benefit. The investment returns on the cash value component are generally lower than what you’d earn investing the premium difference in index funds.

Whole life can make sense in specific estate planning scenarios (large taxable estates, business succession planning), but for the typical family covering income replacement and mortgage, term life provides the same death benefit at a fraction of the cost.

Adjusting for Existing Assets

DIME gives a gross coverage number. Reduce it by assets that serve the same purpose:

• Existing life insurance: Employer policies + any individual policies you already hold
• Retirement savings: A surviving spouse can draw on IRAs and 401(k)s (though be careful not to double-count retirement savings you’re relying on for your own retirement)
• Liquid savings: Emergency fund and taxable investment accounts that could cover debts or income gaps

If you have $150,000 in existing employer coverage and $80,000 in a taxable brokerage account, subtract $230,000 from your DIME total. Net coverage need in our earlier example: $1,085,000 - $230,000 = $855,000, rounded to $1,000,000.

Applying for Coverage: What to Expect

Life insurance premiums depend on five main factors:

1. Age — The most significant factor. Every year older increases premiums, sometimes by 5-8% per year.
2. Health — Insurers require a medical exam (or use your health records). Controlled chronic conditions raise rates; uncontrolled ones may trigger exclusions.
3. Gender — Women typically pay 20-30% less than men for the same coverage due to longer life expectancy.
4. Smoking status — Smokers pay 2-4x the non-smoker rate.
5. Coverage amount and term length — Higher coverage and longer terms cost more, but not proportionally — a $1,000,000 policy is typically less than twice the premium of a $500,000 policy.

Apply sooner rather than later. Locking in coverage at 32 versus waiting until 38 can save you $20,000-$40,000 in total premiums over a 20-year term.

Frequently Asked Questions

Is the DIME method better than the 10x income rule?

For most people, yes. The 10x rule is a starting point, but it ignores your actual debt load, mortgage balance, and education goals. DIME produces a number tailored to your family’s specific needs. If your debts are low and your kids are grown, DIME may actually give a lower number than 10x income.

Should both spouses carry life insurance?

Yes, including a non-working spouse. The economic value of childcare, household management, and caregiving is substantial. A stay-at-home parent’s death creates real financial expenses the surviving spouse must now fund. A $400,000-$500,000 policy for a non-working spouse is reasonable.

How long of a term should I get?

Match the term to your longest financial obligation. If your youngest child is 2 and you have a 30-year mortgage, a 30-year term covers both. If your kids will be out of college in 15 years and your mortgage is paid off by then, a 20-year term may be sufficient.

Does employer-provided life insurance count toward my coverage?

It counts, but don’t rely on it exclusively. Group life insurance typically caps at 1-2x salary, and coverage ends when you leave the job. If you change employers or are laid off, you may have a gap. Employer coverage is a supplement, not a foundation.

Does the DIME method account for a spouse’s income?

Yes — the income replacement component uses your income only, and you should reduce it by any income your surviving spouse would continue earning. If your spouse earns $70,000 and you need $120,000/year to maintain your family’s lifestyle, the income gap is $50,000/year, not the full $120,000.

TL;DR

• Use DIME, not 10x income: Add Debt + Income replacement (10-15 years of the gap your family needs) + Mortgage balance + Education costs — this produces a number specific to your family, not a generic rule of thumb.
• Peak need is ages 35-44: A typical DIME calculation at this stage lands at $800,000-$1,500,000 driven by a large mortgage, young children, and 20+ years of income to replace.
• Term life is almost always the right product: A healthy 40-year-old can get $1,000,000 of 20-year term coverage for around $74/month — whole life costs 10-15x more for the same death benefit.
• Insure the non-working spouse too: A $400,000-$500,000 policy covers the real financial cost of replacing childcare, household management, and caregiving.
• Apply early: Locking in coverage at 32 instead of 38 can save $20,000-$40,000 in total premiums over a 20-year term — age is the single largest premium factor.
