Most people either guess at a life insurance number or Google “how much life insurance do I need” and land on the classic “10 times your salary” advice. That might work for some people. For others, it’s wildly off.
If you’re asking the question at all, you’re ahead of most. The right coverage amount isn’t random. It should reflect what you actually owe, what you earn, who depends on you, and what you want to fund after you’ve passed.
Here’s the framework financial planners actually use: the DIME method. It stands for Debt, Income, Mortgage, and Education. It takes about 15 minutes with a calculator.

The DIME Method: A Step-by-Step Calculator
Grab a piece of paper or open a spreadsheet. We’re going to work through four categories.
D is for Debt
Start by adding up all your outstanding consumer debt, not including your mortgage (that gets its own section). Credit cards, personal loans, student loans, car loans.
Then add final expenses. Funerals and burials typically run between $10,000 and $15,000. You want to make sure your family isn’t selling assets or scrambling to pay off creditors on top of grieving.
Subtotal 1: Consumer Debt + Final Expenses
I is for Income Replacement
This is usually the biggest number. When you die, your paycheck stops. The bills don’t. The idea is to leave a lump sum that, when invested conservatively, replaces your income for however many years your family still needs it.
“10 times your salary” gets thrown around a lot here, but it ignores too much. A better question: how many years does my family need my income? If your kid is two, that might be 20 years. If your youngest is about to graduate, maybe 5 to 10.
Take your annual after-tax pay and multiply it by the number of years. Don’t factor in taxes on this amount since life insurance death benefits are generally income-tax-free.
Subtotal 2: Annual Income x Years of Support Needed
M is for Mortgage
For most families, the house is the biggest monthly expense. If you die, your spouse may not be able to keep up with the payments alone.
The cleanest move is to cover the full mortgage payoff. That eliminates the housing payment entirely and drops the family’s monthly costs dramatically. Check your mortgage statement for the current principal balance.
Subtotal 3: Remaining Mortgage Principal
E is for Education
If you have kids and plan to help with college, this needs to be covered too. You won’t be around to fund a 529 or write tuition checks from your paycheck, so the policy has to handle it.
Estimate tuition plus room and board for the type of school you’d expect them to attend. Multiply by the number of kids.
Subtotal 4: Estimated College Costs x Number of Children
The Final Calculation
Add the four subtotals:
(Debt) + (Income) + (Mortgage) + (Education) = Total Gross Need
But you’re not done. You probably already have some assets working in your favor. Subtract existing savings, investments, and any life insurance you already carry (like a group policy through work).
Total Gross Need – Liquid Assets = Total Life Insurance Needed
The Non-Financial Spouse Factor
Here’s a mistake people make all the time: assuming a stay-at-home parent doesn’t need coverage because they don’t earn a paycheck.
Think about what happens if that parent dies. The working spouse now has to pay for childcare, after-school pickups, cooking, cleaning, and home maintenance. Full-time help for all of that adds up fast. A policy on the non-working spouse keeps the surviving partner from having to quit their job or burn through savings just to keep the household running.
Term vs. Permanent: Making the Coverage Fit the Budget
Once you run the DIME calculation, the number might surprise you. It’s common for a young family to land at $1.5 million or $2 million.
If you try to cover that with a Whole Life or Universal Life policy, the premiums will probably be painful. This is where Term Life makes sense. Term insurance gives you pure death benefit protection for a set period (10, 20, or 30 years) at a fraction of the cost.
For a lot of families, the smart play is to buy a large Term policy during the high-need years, when the kids are young and the mortgage is big. As you age, pay down debt, and build savings, your need for coverage drops naturally.
FAQs
Is the “10 times your income” rule accurate enough?
It’s a decent starting point, but it misses a lot. It doesn’t account for your debts, how many kids you have, or whether your spouse works. A single person with no debt probably doesn’t need 10x. A sole provider with four kids and a big mortgage might need more. The DIME method gives you a number based on your actual situation, not an average.
Should I rely on the life insurance provided by my employer?
Treat it as a bonus, not a plan. Employer policies usually cap out at 1x or 2x your salary, which rarely covers a mortgage and years of income replacement. Worse, those policies aren’t portable. You lose the job, you lose the coverage. Own a personal policy that stays with you no matter where you work.
Do I need life insurance if I am single with no children?
If nobody depends on your income, your need is minimal. That said, consider a small policy to cover final expenses and any co-signed debts. If a parent co-signed your private student loans, your death could stick them with the balance. A small policy prevents that.
How does inflation affect my life insurance needs?
A $500,000 payout today won’t stretch as far in 20 years. When you’re calculating income replacement, add a buffer. If the math says $1 million, consider buying $1.1 or $1.2 million to account for rising costs. This matters more on longer-term policies (20 or 30 years).
Can I change my coverage amount later?
You can usually lower your coverage without much hassle. Increasing it is another story. You’ll need a new application, new medical underwriting, and you’ll be older (and probably paying more). If you’re on the fence, it’s usually cheaper to slightly over-insure now than to buy a second policy later.
How much life insurance do I need based on my salary?
The quick answer is 10 to 15 times your annual income. The better answer is to run the numbers: income replacement, debts, future expenses like college, minus whatever assets you already have.
Should both spouses have life insurance?
Usually, yes. Even if one spouse doesn’t earn income, they’re doing work that would cost real money to replace: childcare, household management, logistics. Covering both spouses protects against either loss.
How often should I review my life insurance policy?
Every few years, or after any major life change: getting married, having a kid, buying a house, a big raise. Your coverage needs shift as your life does.
Structuring Your Financial Foundation
Figuring out your life insurance number isn’t about predicting the future perfectly. It’s about building enough of a buffer that your family can maintain their life if the worst happens. The DIME method moves you from guessing to actual planning.
Life insurance is one of the few things you buy, hoping you’ll never use it. You pay the premiums and hope they’re wasted. But having the right amount of coverage means your debts die with you instead of landing on the people you care about. If you’re unsure about the numbers or which policy type fits your budget, talk with the Matt Patterson Insurance Agency and we’ll walk through it together.
