Ask ten people how much life insurance you need and you will get ten different answers. Some say ten times your salary. Some say enough to pay off the house. Some say whatever you can afford. The real answer is less mysterious than it sounds: add up what your family would need if you were gone, subtract what they already have, and the gap is your number. Here is a simple way to work through that math.
Start with what the money has to do
Life insurance exists to replace what you provide. That is mostly income, but not only income. If you are a stay-at-home parent, you provide childcare, transportation, cooking, and household management that would cost real money to replace. If you are the breadwinner, your family loses your paycheck and possibly your employer health insurance. A good coverage estimate accounts for all of it.
Write down the big categories. Income replacement for the years your family depends on it. Debts that would fall on survivors, like a mortgage, car loans, or credit card balances. Future costs you want covered, especially college for kids. And final expenses, which are smaller than the rest but still worth including so your family is not scrambling for cash in the first weeks.
Then subtract what is already in place. Existing savings, any life insurance through your employer, Social Security survivor benefits if your family qualifies, and any other assets your family could draw on. What is left is the gap your policy needs to fill.
The income multiple shortcut
The fastest estimate is a multiple of your income. A common starting point is 10 to 15 times your annual gross income. So if you earn $80,000 a year, that puts you in the $800,000 to $1.2 million range. This is a rule of thumb, not a calculation, but it is useful because it roughly accounts for replacing your income for a decade or more while interest covers the rest.
Why the range? A higher multiple fits if you are young with small kids and a long horizon of dependency. A lower multiple can work if you are older, your debts are nearly paid, or your spouse has a strong income of their own. The multiple is a starting point. If your situation has big debts or big future costs like college, adjust upward.
Keep in mind that employer-provided life insurance, often one or two times your salary, rarely covers the full gap on its own. It is a nice supplement, but most families need an individual policy on top of it. And employer coverage usually ends when you leave the job, so it should not be the foundation of your plan.
The DIME method, step by step
For a more careful number, financial planners often use the DIME method. DIME stands for Debt, Income, Mortgage, and Education. You estimate each one and add them up.
Debt
Add up everything you owe besides the mortgage: credit cards, car loans, student loans, personal loans. These do not disappear when you die, and your family should not have to pay them out of money meant for living expenses.
Income
Multiply your annual income by the number of years your family would need support. Many planners use 10 years as a baseline. If your kids are toddlers, you might use 15 or 20. If they are teenagers, fewer.
Mortgage
Include the remaining balance on your home loan. This is separated from other debt because it is usually the biggest single obligation, and keeping the family in the home is often the top priority.
Education
Estimate future college costs for each child. This is the fuzziest number in the formula, since college prices vary wildly and change over time. Use a rough figure for the type of school you have in mind, public or private, and do not overthink the precision. A ballpark here is fine.
Add the four together, then subtract liquid assets your family could use: savings, investments, existing life insurance. The result is a coverage amount grounded in your actual obligations rather than a generic multiple.
Do not forget the non-earner
If one partner stays home with the kids, it is tempting to insure only the breadwinner. That is a mistake. Replacing a stay-at-home parent’s labor costs money: full-time childcare, after-school care, housekeeping, transportation, meal preparation. Depending on where you live and how many kids you have, replacing those services can cost as much as a full-time salary.
A common approach is to insure the non-earning spouse for enough to cover several years of childcare and household help. The exact amount depends on your kids’ ages and local childcare costs, but skipping coverage entirely leaves the working parent one crisis away from a financial hole.
Adjusting for your stage of life
Your number is not fixed forever. A 30-year-old with a newborn and a new mortgage needs far more coverage than a 55-year-old with grown kids and a paid-off house. That is normal, and it is one reason term life is popular: you can buy a large policy for the high-need years and let it expire when the need shrinks.
Review your coverage after big life events. A new child, a new house, a divorce, a major raise, or a spouse leaving the workforce all change the math. Most people should revisit their number every few years. If your income has grown a lot since you bought your policy, your coverage may be lagging behind what your family actually needs.
If you are early in this process, it also helps to know how term and whole life compare on cost, since the type of policy changes what a given coverage amount will run you each month. And if you are young, read up on life insurance in your 20s before assuming you should wait.
What if the number feels impossibly large?
Running the DIME method for the first time can produce a number that feels absurd, like a million dollars or more. That is a normal reaction, and it is also normal for the monthly premium on a term policy to be far lower than you would guess. Term life is cheap precisely because it covers a defined risk over a defined period. A million-dollar 20-year term policy for a healthy 30-year-old often costs less per month than a typical streaming and food delivery habit.
If even term pricing strains your budget, buy what you can afford now and plan to increase coverage later. Some term policies let you add coverage or convert to a larger policy without a new medical exam. Partial coverage is far better than none. The biggest mistake is not the wrong number. It is waiting years to buy anything because the ideal number felt out of reach.
A worked example
Say you earn $90,000 a year, owe $320,000 on your mortgage, have $25,000 in other debts, two kids under 8, and $60,000 in savings plus a $100,000 employer policy.
DIME math: debts of $25,000, income replacement of $90,000 times 12 years ($1,080,000), mortgage of $320,000, and education at a rough $100,000 per child ($200,000). That totals $1,625,000. Subtract $160,000 in existing resources, and the gap is about $1.47 million. The income multiple shortcut would have suggested $900,000 to $1.35 million. The DIME number is higher because the mortgage and college costs are large relative to income. Either way, you are in the same neighborhood, and that neighborhood is the point. You are not choosing between $200,000 and $2 million. You are choosing within a range, and any amount in that range is a reasonable decision.
The takeaway
You need enough life insurance to cover your debts, replace your income for the years your family depends on it, keep the mortgage paid, and fund the big future costs like college, minus what you already have. The income multiple gets you a quick estimate. DIME gets you a careful one. Both beat guessing. Run the numbers, buy a term policy that fits the gap, and revisit it when life changes. That is the whole process.
