How much life insurance do I need?
Forget the rules of thumb. Here’s the real method to land on a coverage amount you can actually stand behind — built around your family, not a formula.
If you’re asking how much life insurance you actually need, you’re already asking the right question — and I’m glad you are, because this is the part most people skip. So let me tell you straight. The right amount of coverage is enough to clear your debts, pay off the house, replace your paycheck for the years your family leans on it, and get your kids through school — minus whatever you’ve already got saved and covered. That’s the whole thing, really. And there’s a simple way to land on that coverage amount, one that works a whole lot better than the rules of thumb floating around out there.
Finding your coverage amount, at a glance
- The “10x your income” rule is really just a guess. It ignores your mortgage, your debts, and your kids — so it’s often way too low for a young family.
- A far better method is DIME: add up your Debts, Income to replace, Mortgage, and Education, then subtract what you already have.
- Term life gives you the most coverage for the least money — so you can actually afford the full amount your family needs.
- Don’t skip the stay-at-home parent. Replacing what they do costs real money, starting with childcare.
- Your employer’s policy isn’t a plan. It’s usually a fraction of what you need, and it disappears the moment the job does.
People know in their gut they need life insurance. What stops them cold is figuring out how much.
I’ll be honest with you about something I see all the time. Folks already know they need coverage. Figuring out how much to buy is what trips them up — it feels like a guess, and guessing about something this important is uncomfortable, so they put it off. Sometimes for years. And putting it off is the one thing that actually leaves the people they love unprotected.
That’s the whole reason I’m writing this for you. I want to take that uncomfortable guess and turn it into something you can actually work out — not with a rule of thumb, but with a real method you can run tonight at your own kitchen table, with your real mortgage and your real kids right there in front of you.
Why the easy rule falls short
Why “10 times your income” usually gets it wrong
You’ve probably run into the 10x rule — take your salary, multiply it by ten, and there’s your coverage. It’s everywhere, mostly because it’s easy to remember. I get why it caught on. But easy to remember isn’t the same as right for your family.
The trouble is that it doesn’t know the first thing about you. It never asks what you owe on the house. It doesn’t count your debts. It has no idea whether you’ve got one kid or four, or how little they are. For a young family with a big mortgage, that blind spot can leave them short by hundreds of thousands of dollars. For someone who’s debt-free with savings in the bank, it can swing too far the other way and have you overpaying for coverage you don’t need.
So treat 10x as a rough first glance, nothing more. To figure out the amount your family would truly need, you have to look at your actual life — which is exactly what we’re about to do.
The method that actually works
The DIME method: how to actually size it
Here’s the way I’d do it, and it’s genuinely simple once you see it. It’s called DIME, and instead of pulling a number out of thin air, it builds your coverage amount out of the real things your family would have to cover without you. The letters stand for Debt, Income, Mortgage, and Education. You add those four up, subtract what you’ve already got in place, and what’s left is the amount of coverage your family would actually need.
Let me walk you through each letter — honestly, it goes quicker than you’d think.
The four parts of the DIME formula
Add these four together for your gross number — the full job your family would need done.
What you owe that isn’t the house
Credit cards, auto loans, personal loans. Use the payoff balance, not the monthly payment. The goal is for your family to inherit your stuff, not your bills.
Your paycheck, for the years they’d lean on it
Multiply your yearly income by the number of years your family would depend on it — usually until your youngest is grown and on their own. Ten to fifteen years is a common range. Bump the total up a little to keep pace with rising costs over time.
The payoff balance on your home
Clearing it keeps your family in the house and erases their single biggest monthly bill in one stroke.
Getting each kid through school
A public, in-state four-year runs well over $100,000 all-in today, and private can run far more. Pick a realistic number per child.
How the four DIME pieces add up to a gross need — then subtract down to your real coverage number.
Your own student loans usually don’t need insuring — but your kids’ loans are a different story.
Here’s one that trips up almost everybody. Federal student loans get wiped clean when you die, and so do the Parent PLUS loans you took out for your kids’ school — those go right along with you. But if your child is the one who borrowed and you only co-signed, your passing doesn’t erase that debt — they’re still on the hook for every dollar of it. And their future tuition still has to come from somewhere no matter what. So go ahead and cross your own student debt off the list, but keep anything tied to your kids squarely on it.
The biggest piece
How much income do you really need to replace?
This is the biggest piece of your coverage, and I want to slow down here, because it’s where a lot of well-meaning advice quietly steers people wrong. You’ll hear it put this way: once you’re gone, you stop spending on yourself — your food, your gas, your hobbies — so your family only needs to replace about 70 to 80% of your income. Knock off 20 to 30%, they say, and you’re close enough.
I’d be careful trusting that, and here’s why. When you’re raising a family, almost none of your costs actually drop when one person is gone. The mortgage doesn’t shrink. The electric bill is the same. You’re still cooking for the kids, so the grocery run barely changes — nobody starts making three plates instead of four for a recipe that feeds the whole table. Cut your coverage by a fifth on the assumption that life suddenly gets cheaper, and you can leave your family short right when they’ve got the least room to absorb it.
Now, a few things genuinely do fall away — but it’s a short list, and only the ones that fit your life count. A car payment, if that car goes away. The gas and wear of driving to and from your job every day. Your own health insurance premium, if it wasn’t already a family plan. And any personal subscriptions your family won’t need anymore — a phone line, a streaming service, that kind of small stuff.
Look at that list. It’s real, but it’s not much money. So instead of lopping 20% off the top because a formula told you to, just subtract the few things that truly disappear — and don’t talk yourself into a smaller policy than your family actually needs.
And I’d be doing you a disservice if I didn’t mention the other side of this, because it surprises people. Some of your costs can actually go up. If the person who’s gone handled work the one left behind can’t — mowing the lawn, shoveling the driveway, fixing what breaks, keeping the house clean — then somebody has to take it on, or it gets hired out. That’s real money, easily a couple thousand dollars a year. And be honest with yourself: with little kids in the house, or a bad back, the parent left standing may simply be too stretched holding everything else together to ever get out to the yard. So it gets paid for — not because anybody’s being fancy, but because there’s no other way to keep the house running.
The 10x rule exists because it’s easy to say, not because it’s right. For a family with a mortgage and young kids, it can miss the mark by half a million dollars.
The step most guides skip
What to subtract to find your real coverage number
Okay — adding up D, I, M, and E gives you the gross amount. But here’s the step a surprising number of guides leave out entirely: you don’t have to insure money your family already has sitting there. So now you subtract it back out.
Here’s what counts. Your liquid savings — the cash and regular investment accounts your family could actually get their hands on. Any existing life insurance — a policy you already own, plus whatever your job provides, though read the warning below before you lean on that part. And Social Security survivor benefits — real money for a spouse raising young kids, and a lot of people don’t even know it’s coming. Just know the limits there: it stops once the child is grown, and it won’t touch college. Count it, but don’t build your whole plan on it.
And here’s the one thing you should not subtract: your retirement accounts. That money is your spouse’s retirement, and it needs to stay that way. Draining it early to cover today’s bills just trades one hardship for another, with taxes and penalties piled on top. Leave it right where it is.
Whatever’s left after you subtract all that — that’s your real coverage amount. Round it up to the next clean milestone, and there’s your target.
The quick reference: what you add up, and what you subtract back out.
The 10x rule vs. the DIME method
The easy guess against the honest method — and why they so often land in different places.
The 10x rule
One number, done — but it doesn’t know your life.
The DIME method
Built around the life you actually live.
Worked out your coverage amount and not sure what to make of it?
That’s exactly what I help people sort out
The coverage people forget
Don’t forget the stay-at-home parent
Now, if one parent stays home with the kids, it’s awfully tempting to figure they don’t need coverage — no paycheck, no need, right? I understand the logic, but it’s one of the most expensive mistakes a family can make. The day that parent is gone, the working parent suddenly has to pay for everything they were quietly handling, and one bill lands almost immediately: childcare.
You’ll see splashy headlines slapping a six-figure “salary” on what a stay-at-home parent does. They’re fun to read, but that’s not the figure you insure. What you insure is the real cost to replace the work. Full-time childcare by itself often runs $12,000 a year or more for one young child, and that’s before all the chores and errands somebody now has to pick up. Add up what you’d genuinely have to pay to cover it all, multiply by the years until the kids are grown, and you’ll have a real, defensible amount — usually a healthy chunk of coverage on a 15- or 20-year term.
Don’t mistake your work life insurance for a plan.
Most employer policies cover one or two times your salary — which sounds fine until you run DIME and see it’s a small fraction of what your family needs. Worse, it’s tied to the job. Leave, get laid off, or get sick and have to stop working, and the coverage walks out the door with you — often at the exact moment a health change would make a new policy expensive or impossible to get. Count it as one of your subtractions, but never as your strategy. Your real coverage should be a policy you own, that goes where you go.
How long, and what kind
How long should a term life insurance policy last?
The other question people always have is how long the coverage should run. The answer is to match it to your highest-risk stretch — the years your family would be hit hardest if you weren’t there. That’s when the kids are still home, the mortgage balance is still big, and the savings haven’t fully built up yet.
A 20-year term is the usual choice for a family with young kids — it carries you through the dependent years and knocks out a big chunk of a typical mortgage. A 30-year term tends to fit younger buyers in their late twenties or early thirties: very young kids, a brand-new 30-year mortgage, or anyone who wants to lock in a low rate now, before their health has a chance to change.
The thing to hold onto is this: your need for coverage isn’t fixed in stone. It’s at its highest when the kids are little and the mortgage is new, and it eases off year by year as the loan gets paid down and the kids grow up and head out on their own. You’re covering a window of years — not signing up for something forever.
Does term or whole life change how much you need?
Last thing on sizing, and it’s a fair question: does the kind of policy you pick change how much you should get? For figuring out the amount, here’s what actually matters — term life gives you far more coverage for every dollar you spend. That’s the whole reason it’s the right tool here: it lets you reach the full amount your family needs, instead of buying a smaller permanent policy and quietly coming up short.
Whole life costs quite a bit more for that same death benefit. The trade is that it lasts your entire life and builds cash value, and it absolutely has its place — usually when the need is permanent rather than tied to your kids growing up. But when the job in front of you is covering the mortgage, replacing your income, and getting the kids through those dependent years, term is what gets you all the way to the right amount on a budget that still works for your family.
Who needs a big term policy — and who doesn’t?
No single answer fits everyone. Here’s my honest read on where a large DIME-based term policy belongs.
When a large term life policy makes sense
- Have a mortgage, kids, and an income your family counts on.
- Are the only earner, or one of two earners both needed to cover the bills.
- Stay home with the kids — your replacement cost is real and worth insuring.
- Carry meaningful debt that would land on your family.
- Are young and healthy and can lock in a low rate now.
When term life insurance isn’t the right fit
- Have no dependents, a paid-off house, and solid retirement savings — the need has mostly passed.
- Have enough assets that your family could absorb the loss of your income.
- Are mainly after a permanent death benefit or estate planning — that’s a different tool.
A young family of four — and the half-million-dollar gap the easy rule never saw.
Let me show you what this looks like with real numbers, because it lands better than any explanation. Picture a family: one parent earning $90,000, the other $55,000, two kids ages four and seven, $280,000 left on the mortgage, and another $35,000 owed on the cars and student loans. Run DIME on the higher earner — $35,000 in debt, around $1,080,000 to replace twelve years of income, the $280,000 mortgage, and roughly $260,000 to get both kids through college. That comes to a gross amount near $1.66 million. Subtract their savings, the small policy through work, and a fair estimate of survivor benefits, and the honest coverage amount lands right around $1.4 million. The old 10x rule would’ve told that family $900,000 and called it a day — leaving them short by half a million dollars, almost entirely because it never once looked at the mortgage or the kids.
Same family, same life, two completely different answers. Only one of them tells the truth.
The same family, two answers — and the half-million-dollar gap the easy rule never sees.
Common questions about how much life insurance you need
The ones I hear most often, answered plainly.
Do I use my income or our household income?
Use what your family would actually lose if you were gone — so, your income. If you both work, run the whole thing separately for each of you, because you each carry a different piece of the load.
Do my 401(k) and retirement accounts count as coverage I already have?
No — leave those out. That money is your spouse’s retirement, and raiding it early just creates a second problem on top of the first.
My spouse works full-time. Do we still need a lot of coverage?
Usually, yes. The income you’d need to replace might be smaller, but the mortgage, the debts, and the kids’ education don’t shrink one bit. Run DIME for each of you and you’ll see it clearly.
Does whole life give me more coverage for the same money?
Actually the opposite — it gives you less. For covering your income, the mortgage, and the kids, term hands you the most protection for every dollar.
When should I run these numbers again?
Any time life shifts in a big way — a new baby, a new house, a real raise, a debt paid off. A good rhythm is every few years even if nothing major changes. Your need moves over time, and your coverage should be able to move with it.
Let’s find your real coverage number together
You came in wanting to know how much coverage you need, and now you’ve got a real way to figure it out — that’s further than most people ever get. The last little stretch is making sure the amount truly fits your life: your mortgage, your kids, your budget. That’s the part I’d love to help you with. I work for you, not an insurance company, so you’ll get a straight answer from me either way — even if it turns out you’re already in good shape.
