If you have ever asked how much life insurance do I need and walked away with a shrug, you are in good company. It is the single most common question I get, and most of the answers floating around are either a lazy rule of thumb or a sales pitch dressed up as math.

There is a better way. It is called the DIME method, and it takes about ten minutes with a notepad. I have used it with clients since 2008 because it does something a generic multiplier can’t: it builds your number out of the actual bills your family would still be holding.

Why “10 times your salary” is a starting point, not an answer

The 10x rule is popular because it is easy. Multiply your income by ten, buy that, move on. It is not useless. For a lot of young families it lands in a reasonable neighborhood.

The trouble is that it ignores everything specific about you. Two people earning $90,000 can have wildly different needs. One rents, has no kids, and has $8,000 in debt. The other has a $600,000 mortgage, three children under ten, and a spouse who left the workforce. The 10x rule hands both of them $900,000 and calls it a day. It also ignores the direction your life is moving: a 32-year-old with a newborn has roughly 25 years of dependency ahead, while a 58-year-old with grown kids and a nearly paid-off house has almost none.

Use 10x as a sanity check. To actually answer how much life insurance do I need, use DIME.

What the DIME method is

DIME is an acronym for the four buckets of money your family would need if your paycheck stopped permanently:

• D — Debt. Everything you owe except the mortgage, plus final expenses.
• I — Income. Your annual income multiplied by the number of years your family would need it replaced.
• M — Mortgage. Your remaining mortgage balance.
• E — Education. What it would cost to get your kids through school.

Add the four together. Subtract what you already have — savings, existing coverage, group life at work. What is left is your gap. That gap is the policy you should be shopping for.

The reason I like DIME is that every number in it is one you can look up. No guessing at rates of return or inflation assumptions — it is arithmetic on your own balance sheet. Here is how to fill each bucket.

D — Debt and final expenses

Pull every balance that would not disappear when you do: credit cards, car loans, student loans, personal loans, any business debt you personally guaranteed. Private student loans are the one people forget — federal loans are generally discharged at death, but many private loans are not, and a co-signer can be left holding them.

Then add final expenses. Funerals, medical bills that outlive the patient, estate paperwork. Most families should budget somewhere in the $10,000 to $20,000 range for this, and more if there is a long illness involved.

I — Income replacement

This is the biggest bucket and the one people lowball. Take your gross annual income and multiply it by the number of years your family needs it.

How many years? I ask clients to pick the honest answer, not the comfortable one. If your youngest is three, you are probably looking at 15 to 20 years before the household is on its own feet. If your spouse would need to retrain or re-enter the workforce, add time. If your spouse earns well and would keep working, you can trim it.

Do not automatically subtract Social Security survivor benefits here. They help, but they are narrower than people assume. Children generally receive 75% of the parent’s benefit, and a surviving spouse can qualify at any age while caring for the deceased parent’s child — but the child’s benefit typically stops at 18, or 19 if they are still in high school full time. There is also a family maximum that reduces everyone’s payment when the total runs past the cap. And the one-time death payment is $255. That is not a typo. You can read the current rules on the Social Security Administration’s survivor benefits page.

M — Mortgage

Use your current payoff balance, not your original loan amount and not your home’s value. Call your servicer or check your statement.

People ask whether they should just buy mortgage protection insurance instead. Usually no. That is a separate product, often more expensive per dollar of coverage, and the payout goes to the lender rather than your family. Folding the mortgage into one term policy keeps the money in your spouse’s hands, where they can decide whether to pay the house off or invest it and keep making payments.

E — Education

If you have kids and intend to help with college, this bucket is real money. For 2025-26, the College Board puts average published tuition and fees at $11,950 for in-state students at public four-year schools and $45,000 at private nonprofit four-year schools. Room and board is on top of that. Multiply by four years, then by the number of children, then decide what share you actually intend to cover.

Plenty of families cover half and expect the kid to handle the rest. That is a fine answer — just write down the number you actually mean.

How much life insurance do I need? A worked example

Here is a household I see constantly. Sarah is 36, earns $110,000, married to Marcus who earns $65,000. Two kids, ages 4 and 7. They own a home in Queens.

Bucket	What goes in it	Amount
D — Debt	Car loan $18,000, credit cards $9,000, private student loan $22,000, final expenses $15,000	$64,000
I — Income	$110,000 × 16 years (until the youngest is 20)	$1,760,000
M — Mortgage	Remaining payoff balance	$480,000
E — Education	Two kids, roughly half of a four-year in-state public education each	$110,000
Subtotal		$2,414,000
Minus savings	Emergency fund and brokerage	-$85,000
Minus group life	2× salary through her employer	-$220,000
Coverage gap		$2,109,000

So Sarah shops for about $2 million of term life. That number probably looks enormous next to the 10x rule’s $1.1 million. It is not enormous — it is what the arithmetic says. And here is the part that surprises people: at 36 and in good health, that policy costs less per month than her family’s phone bill.

Two notes on the example. I counted Sarah’s income only. Marcus needs his own calculation, and stay-at-home spouses need one too, because replacing childcare and household work costs real money even though no paycheck disappears. And I subtracted her group life at work, but I would not lean on it — group coverage ends when the job does, and it rarely follows you out the door.

Why the number scares people less than they expect

The reason most people never run this math is that they have already decided they can’t afford the answer. LIMRA’s 2026 Insurance Barometer Study found that about half of U.S. adults own life insurance, and that roughly 74 million Americans say they need it while another 24 million say they need more than they have. Cost misperception is a big part of why.

The same study asked people to price a basic term policy. The gap between what they guessed and what it actually costs is the whole ballgame:

Age group	What people guessed it costs per year	What it actually costs per year
Under 31	$1,200	$192
31–35	$900	$204
36–40	$500	$252

Source: LIMRA 2026 Insurance Barometer Study. People under 31 guessed roughly six times the real price. That misjudgment is why a lot of families walk around uninsured while believing they made a reasoned financial decision.

If you want to skip the notepad, the life insurance calculator runs the same DIME logic and gives you a number in about two minutes.

Where DIME needs adjusting

DIME is a strong default, not scripture. How much life insurance do I need is a question with a few honest exceptions, and here are the situations where I change the math:

1. You have significant assets. If you have a large portfolio, the income bucket shrinks. Your family isn’t replacing your paycheck for 20 years — they are bridging a gap.
2. You own a business. Buy-sell agreements and key-person coverage sit on top of your personal number. They are a separate calculation entirely.
3. Your spouse doesn’t work outside the home. DIME’s income bucket reads as zero, which is wrong. Price out childcare, and add it as an income equivalent.
4. You have a special-needs child. Dependency may never end. The income bucket stops being a term calculation and starts being a permanent one.
5. You’re close to retirement, debt-free, and the kids are launched. All four buckets may be near zero. That is a legitimate result. Not everyone needs coverage forever.

Turning your number into an actual policy

Once you have a number, three decisions remain.

Term length. Match it to the longest obligation in your buckets. Sarah’s youngest is 4, so a 20-year term carries her to the far side of the dependency window. If your mortgage has 27 years left, look at 30. Don’t buy a 10-year term for a 20-year problem — you will be re-shopping at 46 instead of 36, at a considerably worse price.

Term or permanent. For the overwhelming majority of families running DIME, term is the answer. Your need is temporary by design — it shrinks as the mortgage amortizes and the kids grow up. Permanent coverage solves different problems, and I go through the tradeoffs in detail in my guide on term life vs. whole life.

Laddering. Instead of one $2 million policy, buy $1.2 million on a 20-year term and $800,000 on a 10-year. The second one drops off when the debts are gone and the premium falls with it. It takes a little more work to set up and usually saves real money.

The half of the calculation almost nobody runs

Here is the biggest blind spot in this entire exercise. DIME answers what happens if you die. It says nothing about what happens if you get hurt or sick and can’t work — which is far more likely during your working years. And a disability is financially worse than death in one specific way: the income stops, but the expenses don’t. You are still eating, still on the health plan, and now you may have medical bills and care costs on top.

Your family needs both sides covered. Term life handles the death scenario. Disability insurance handles the far more likely one, and it is the coverage people skip most often. Run the parallel math with how much disability insurance you need, and if you have a new baby in the house, the newborn checklist walks through the whole sequence.

Both of these are income protection. That is the actual product. Life insurance and disability insurance are just the two halves of it.

How much life insurance FAQ

Should I subtract my group life insurance at work from my number?

Subtract it, but discount it. Group coverage typically ends when the job does, and most employers offer only one to two times salary — nowhere near a DIME number. Treat it as a bonus layer sitting on top of a policy you own personally, not as the foundation.

Does a stay-at-home parent need life insurance?

Yes. Run DIME with an income figure that reflects what it would cost to replace the work: childcare, transportation, household management. In a high-cost metro like New York that can run $50,000 to $70,000 a year. The paycheck is invisible; the expense is not.

How often should I redo this calculation?

Any time a bucket moves. New baby, new mortgage, a big raise, paying off the student loans, a divorce. Absent any of that, every three years is a reasonable cadence. Most people are underinsured not because they never bought coverage, but because they bought it in 2014 and never looked again.

Isn’t $2 million of coverage going to be unaffordable?

Usually not, if you are reasonably healthy and buying term. As the LIMRA data above shows, most people badly overestimate the price. Get a real quote before you decide you can’t afford it — the guessing is what costs families their coverage.

What if I have a health condition that will drive my rate up?

Then carrier selection matters more than anything else in this article. Underwriting for conditions like diabetes, sleep apnea, or a history of cancer varies enormously between companies — the same applicant can be rated Standard at one carrier and declined at another. This is precisely the situation where an independent broker who compares 25+ carriers earns their keep. There are also no-medical-exam options worth understanding.

Should I buy the whole amount at once, or build up to it?

Buy what you need now, while you are as young and healthy as you will ever be. Rates are locked at issue, so waiting is what makes coverage expensive. If cash flow is genuinely tight, buy the largest term policy you can afford today and add a second layer later rather than waiting for a year when the budget feels roomier. That year has a way of not arriving.
