You sit down without a licensed insurance agent to try to figure out how much life insurance you need, and within 10 minutes you want to close the laptop.
One calculator says ten times your income. The next says twelve. A guy on YouTube swears by some formula with an acronym. And every single one of them spits out a different number…
So you do what most people do. You pick something that sounds responsible, or you put it off for another year. I get it. But I want to save you from both of those, because the problem isn't that you can't do the math. The problem is that almost everyone starts with the wrong question.
The better question
People ask me, "Kevin, how much life insurance do I need?"
And my honest answer is: I don't know yet. Because "need" is the wrong word to start with.
Here's the better question — the one that actually gets you to a real number: if you were gone tomorrow, what would you want your family to be able to keep? The house. The kids' school. Your spouse's ability to grieve for a year before making a single big decision. The plan you had, instead of the plan a crisis forces on them.
That's what life insurance is really for. Not to replace your paycheck. To protect your family's choices. The paycheck is just one of the things that buys those choices.
I'll show you how to land on an actual dollar figure in a minute. But hold onto that distinction, because it changes the whole calculation.
Why "ten times your income" leaves people exposed
Let me be fair to the rule of thumb first. "Ten times your income" isn't wrong, exactly. It's a doorway. It gets a number on the table in thirty seconds, and a rough number beats the zero most people are walking around with.
But here's where it quietly fails you. It only looks at your salary. It never asks what you owe, what your kids will need, or what your family already has sitting in the bank.
I worked with a man — I'll call him Dave, 38, two little kids, earning $75,000 a year. The rule said $750,000 and call it a day. Sounds like a lot of money, right?
Now look at his actual life. A $250,000 mortgage. Two kids who'll want college in fifteen years. A wife who'd need time, not a fire sale of the house. Run that honestly and $750,000 doesn't stretch nearly as far as it sounds. He'd have been "covered" on paper and short in real life. That's the gap a rule of thumb hides.
Build the foundation before the walls
Before I give you the formula, one principle I never skip, because it's the whole game: you protect the downside before you chase the upside.
Think about building a house. Nobody frames the walls before the foundation is poured. You'd be insane to. Yet with money, people do it backwards all the time — they pour everything into growth and leave the foundation cracked. Life insurance is foundation. It's the thing that keeps one bad day from collapsing everything you've built for the people you love.
So we're not guessing at a number. We're pouring a foundation. Here's how you size it.
The method: add up four things, subtract what you've got
I use a simple framework called DIME. Four letters, four things your family would still have to deal with if your income disappeared. Let's walk Dave through it with round numbers so the math stays easy.
D — Debt. Everything you owe that isn't the mortgage, plus a cushion for final expenses. Funerals cost more than people think — budget $10,000 to $15,000. Dave's other debts and final costs: call it $25,000.
I — Income. Here's the one that matters most. Multiply what you earn by the number of years your family would lean on it. Dave's youngest is little, so figure 15 years. $75,000 × 15 = $1,125,000. That's the number that keeps the lights on and the routine intact while everyone finds their footing.
M — Mortgage. Pay off the house and your spouse never has to wonder if they can stay. Dave's balance: $100,000.
E — Education. What you'd want to put toward the kids' future. Two kids, roughly $120,000.
Add it up: $25,000 + $1,125,000 + $100,000 + $120,000 = $1,370,000.
Now the step the calculators love to skip. Subtract what already exists. Dave has $150,000 in group life through work and $40,000 in savings — $190,000 he doesn't have to insure twice.
$1,370,000 − $190,000 = $1,180,000.
So Dave needs somewhere around $1.2 million — not the $750,000 the rule of thumb promised, and not some scary made-up figure either. A real number, built from his real life. And here's the part that surprises people: at 38, a 20-year term policy for that amount costs less per month than what a lot of folks spend on coffee.
"Okay, but isn't that a lot of coverage?"
I know what you're thinking: that's a big policy — is he just trying to sell me more insurance?
Fair. So let me argue the other side honestly. Could Dave buy less? Absolutely. If money's tight, a smaller policy today beats the perfect policy you never get around to buying. Some coverage in force tomorrow morning is worth more than the ideal spreadsheet you'll finish "someday."
But here's what "less" actually costs. The day something happens, the gap doesn't vanish — it just lands on your family instead of the insurance company. Underinsure, and a grieving spouse sells the house too fast, or a kid trades the school they wanted for the one you could suddenly afford. Those aren't line items. Those are your family's options, quietly disappearing at the worst possible moment.
That's the trade. You're not buying a bigger number. You're buying their freedom to not make a forced decision while they're heartbroken.
Don't forget the parent who doesn't bring home a paycheck
One more place people get it backward: the stay-at-home parent.
The logic sounds reasonable — "they don't earn an income, so what's to replace?" Then something happens, and the surviving spouse runs headfirst into the bill for everything that parent quietly did. Childcare. Running the household. The hundred things that were free because someone you love was doing them.
Price that out, and it's not free at all — childcare alone runs $15,000 to $30,000 a year in many places. A stay-at-home parent needs real coverage too. Not because of a paycheck. Because of everything that paycheck never measured.
Term or whole life?
You'll want to know, so here's the straight version — no sales pitch.
Term covers you for a set stretch — 10, 20, 30 years — for the lowest cost. It's the right tool when you've got a window of big obligations: the mortgage years, the kids-at-home years. Most families' core coverage should be term. It's honest, it's cheap, it does the job.
Whole life lasts your whole life and builds cash value you can borrow against. It costs more, because it's doing more and it's permanent. It earns its keep in specific situations — business succession, estate planning, leaving a guaranteed legacy, or as a stable foundation piece inside a larger plan.
Neither one is "the answer." They're different tools for different jobs. Anybody who tells you one is always right is selling, not planning.
So — what now?
Here's where it comes down to a choice.
You can keep letting a rule of thumb pick a number that looks fine on paper and quietly leaves your family short. Or you can spend fifteen honest minutes — debts, income, mortgage, education, minus what you already have — and pour a foundation that actually holds.
One of those protects your family's choices. The other just protects your sense that you handled it.
You already know which kind of person you are. So do the fifteen minutes.
A few quick questions I get all the time
Do I really need life insurance if I'm young and healthy? If someone depends on your income — a spouse, kids, even a co-signed loan — then yes. And young-and-healthy is exactly when it's cheapest. Waiting doesn't make you more insurable. It only makes the price go up.
Is the coverage from my job enough? It's a start, and you should absolutely count it (Dave did). But it usually tops out lower than your real need, and here's the catch most people miss: it walks out the door the day you leave the job. Don't build your foundation on something that isn't yours to keep.
My kids are grown and the house is paid off. Can I drop my coverage? Often your need does shrink as the obligations fall away — that's the plan working. But "drop it" depends on what's left: a surviving spouse's income, final expenses, anything you want to leave behind. Recalculate before you cancel anything.
How often should I redo this? Anytime life moves — a new baby, a new house, a raise, a payoff. Otherwise, every couple of years. The number isn't permanent, because your life isn't.
One honest note: everything above is education, not personal advice. I'm a CFP, but I'm not your planner until we've actually sat down and looked at your specific situation — your goals, your numbers, your family. The framework here gets you a smart, realistic estimate. The right final answer is the one built around you.
