Life Insurance DIME Method: How Much Coverage You Actually Need

Last reviewed 16 September 2026.

The short answer

DIME is a four-factor worksheet for estimating how much life insurance a household needs: Debt, Income replacement, Mortgage, and Education. You add those four figures to get a gross need, then subtract what your family would already have — employer group coverage, earmarked savings, retirement accounts, and Social Security survivor benefits — to get a net need.

Most explanations of DIME stop after the addition step. That is the step that produces an alarming number and no useful decision. The subtraction step is what turns the worksheet into an actual coverage amount, and the second half of this page is about a mistake that costs households real money: treating the income figure as a lump sum when it is really an annuity.

What each letter covers

D — Debt

Every balance that would survive you and land on your family: credit cards, personal loans, auto loans, student loans in your name, medical bills, and any co-signed obligation. Exclude the mortgage here — it has its own letter, and keeping it separate stops it from being double-counted.

One thing people routinely forget: debt does not disappear at death. Credit-card balances and personal loans are claims against your estate. Federal student loans are discharged on death, but private student loans often are not.

I — Income replacement

The income your household depends on, expressed as a number of years. Common practice is 5 to 10 times annual income, but the multiple is doing more work than most people realise — see the section below.

Use take-home pay, not gross. Income tax stops at death, and using gross inflates the need by 20–30% for a typical earner.

M — Mortgage

The current payoff balance, not the original loan amount and not the remaining payments. Your servicer can give you the exact payoff figure. The purpose is specific: to let the family stay in the home without a forced sale.

E — Education

Estimated future tuition and fees for each dependent. Use current published prices for the type of school you are actually planning for, then decide whether to adjust upward. Four years at an in-state public university and four years at a private university differ by a factor of three or more, so the assumption matters more than any other line on the sheet.

The worksheet, step by step

Step	Line	What to enter
1	Income replacement	Years of income you want to replace × annual take-home pay
2	Mortgage	Current payoff balance
3	Other debt	Credit cards, auto loans, personal loans, medical balances
4	Education	Estimated total future tuition and fees per child
5	Gross need	Sum of steps 1–4
6	Final expenses	Funeral, burial, and any out-of-pocket medical costs not covered
7	Employer group life	Death benefit available through work
8	Earmarked savings	Cash or investments your family could actually draw on
9	Retirement accounts	Balances your survivors would inherit
10	Survivor benefits	Social Security survivor benefits, if dependents qualify
11	Net need	(Step 5 + step 6) − steps 7–10

Step 6 is not part of DIME’s acronym, but leaving it out understates the need. Funeral and burial costs typically run in the range of $8,000 to $12,000 depending on services and location, and they come due within weeks of death — before any policy pays out.

A full worked example

Household: one earner with $70,000 annual take-home pay, a $250,000 mortgage balance, $20,000 in other debt, two children with an estimated $120,000 of combined future tuition, and a 10-year income-replacement target.

Gross need

Line	Amount
Income: 10 × $70,000	$700,000
Mortgage payoff	$250,000
Other debt	$20,000
Education	$120,000
DIME subtotal	$1,090,000
Final expenses	$10,000
Gross need	$1,100,000

Existing resources

Line	Amount
Employer group life (1× salary)	$70,000
Savings earmarked for family	$60,000
Retirement account balance	$85,000
Total existing	$215,000

Net need: $1,100,000 − $215,000 = $885,000

At this point the household is shopping for roughly $900,000 of coverage, not $1.1 million. That is a material difference in premium — and it is the difference between a number that gets acted on and a number that gets abandoned because it sounds unaffordable.

Note what is deliberately excluded from the “existing resources” side: the primary residence’s equity. Counting home equity as a resource available to survivors is only honest if the family intends to sell the home, which is the exact outcome the “M” in DIME is trying to prevent.

The part that actually changes the answer

The 10× income convention produces $700,000 in the example above. But that figure assumes the payout is simply spent down at $70,000 a year with no return. A lump sum sitting in a conservatively invested account earns something. If you want to fund $70,000 a year for 10 years, the amount you actually need depends on the real return you assume:

Assumed real return	Lump sum needed to pay $70,000/yr for 10 years
0% (pure drawdown)	$700,000
2%	≈ $628,800
4%	≈ $567,800
5%	≈ $540,500

The same arithmetic applied to a 20-year target is more striking: 20 × $70,000 = $1,400,000 by simple multiplication, but funding $70,000 a year for 20 years at a 4% real return requires about $951,300.

Two cautions before you shorten your coverage on the strength of this table. First, the money has to actually be invested — a lump sum left in a chequing account delivers the 0% row. Second, real return is return after inflation, and a portfolio with a heavy bond allocation may not clear 4% real over a decade. Using a lower assumption is the conservative choice, and there is nothing wrong with buying a round number above the calculated figure.

How DIME compares to the other common methods

Method	What it does	Best for	Weakness
DIME	Adds four concrete obligations	Households with a mortgage, debt and children — the most common situation	Ignores the earning power of the lump sum; needs the subtraction step to be useful
Multiple of income (10–15×)	Multiplies salary by a factor	A 30-second sanity check	Says nothing about your actual obligations; ignores existing coverage entirely
Capital needs analysis	Models income, expenses, inflation and returns year by year	Complex households, business owners, uneven income	Needs an advisor and detailed inputs
Human life value	Present value of your future earnings	Litigation and high-earner contexts	Produces very large numbers that are hard to act on

DIME is the right starting point for most households precisely because it is concrete. It becomes a decision rather than a guess once you subtract existing resources and convert the income line into a present-value figure.

What DIME leaves out

• Survivor Social Security. Children under 18 and a surviving spouse caring for a child under 16 may qualify for survivor benefits, subject to a family maximum. These typically end when the youngest child turns 18, which means they offset the early years but not the mortgage or the education line. Get your own estimate from your Social Security statement rather than assuming.
• A stay-at-home parent. DIME assumes the insured person’s income needs replacing. If a parent provides childcare rather than income, their death creates a cost that DIME does not capture — replacing that care is a real, recurring expense.
• Inflation. The education line in particular is stated in today’s prices. Tuition has historically risen faster than general inflation.
• Business succession. If you own a business, a buy-sell agreement funded with insurance is a separate analysis.
• Timing. DIME produces a single number, but needs change shape over time. A mortgage gets smaller; children get more expensive. That is an argument for layering term policies — for example $500,000 of 20-year term plus $400,000 of 10-year term — rather than buying one policy for the whole amount at the longest term.

Estate tax context for 2026

For 2026 the federal estate and gift tax exclusion is $15,000,000 per person (One Big Beautiful Bill Act, Pub. L. 119-21, made permanent). A life insurance policy owned by the insured is generally included in their taxable estate, but at that exclusion level very few households have federal exposure from insurance alone. If your total estate approaches the threshold, an irrevocable life insurance trust (ILIT) can hold the policy outside the estate — that is a conversation for an estate attorney, not a general guide.

State-level estate or inheritance taxes are a separate question and exist in a minority of states with much lower thresholds. Check your own state before assuming there is no exposure.

Frequently asked questions

What does DIME stand for in life insurance?

Debt, Income, Mortgage, Education. You add those four figures, add final expenses, and then subtract existing coverage, savings, retirement balances and survivor benefits to get a net need.

How many years of income should I replace?

Most planners use 5 to 10 times annual income. The better way to choose is to pick the year you want the youngest dependent to be financially independent, then apply the present-value arithmetic above rather than the raw multiple — the multiple overstates the need if the payout will be invested.

Does DIME include my mortgage?

Yes, as its own line using the payoff balance, not the original loan amount. It is kept separate from other debt so the family can stay in the home rather than sell it.

Should I subtract my 401(k) and savings?

Yes — and this is the step most guides omit. A worksheet that only adds produces a number that is too high, which leads people to either overbuy or give up on the exercise. Exclude home equity unless the family genuinely intends to sell.

Is DIME accurate enough to buy a policy?

It is accurate enough to decide a range and a term length, which is what most households actually need. Get quotes for a round number above your net need, and revisit the worksheet when your mortgage balance, family size or income changes materially.

Does DIME work for a stay-at-home parent?

Partly. The worksheet captures debt, mortgage and education, but not the cost of replacing unpaid care. For a non-earning parent, replace the “income” line with the annual cost of the childcare, transport and household services that would have to be purchased.

Does life insurance count toward the 2026 estate tax?

A policy owned by the insured is generally included in the taxable estate. With the 2026 federal exclusion at $15,000,000 per person, most households have no federal exposure. Large policies can be held in an ILIT to keep the proceeds outside the estate.

How often should I redo the calculation?

Annually is reasonable, and mandatory after any of these: a new mortgage or refinance, a new child, a significant income change, or paying off a major debt. Each of those moves one of the four DIME lines directly.
