How Much Life Insurance Do You Actually Need? The Math a Texas Family Can Do Tonight

Nate Mclaughlin • October 15, 2026

Income multiples get you in the neighborhood, the DIME method gets you a number you can defend, and neither one is a quote until underwriting has its say.

Picture a family on a county road outside Boyd: Dale drives for a trucking outfit out of Decatur, his wife Marisol is home with their two kids, and they carry a mortgage, a truck note and a lot of plans. This is a made-up family, but the question they ask at the kitchen table is a real one. If Dale's paycheck stopped tomorrow, what would it take to keep the house, the lights and the kids' plans intact?

The plain answer is that a wage-earner usually needs enough life insurance to cover debts, replace income for as many years as the family would need it, and fund big goals like college. A common rough starting point is 10 to 12 times annual income, but the better answer is a worked calculation called the DIME method, which adds up Debt, Income replacement, Mortgage and Education. Either way, the result is a coverage amount, which is the lump sum your named beneficiaries would receive, and it is not a quote or a price.

Start with what the money has to do

Life insurance is protection, a lump sum paid to the people you name if you die, so the first job is deciding what that lump sum has to accomplish. Some families need it to cover the mortgage and keep the kids in their school. Others mainly need to give a spouse a year or two of breathing room. Writing the jobs down before you pick a number keeps you from guessing, and it gives you something concrete to talk through with a spouse.

Say Dale and Marisol both think of this as Dale's problem alone. Marisol, as a stay-at-home parent, carries childcare, driving, meals and a hundred other jobs that would cost real money to replace, so a non-earning parent needs coverage too. Sizing that coverage is its own exercise, built on what it would cost to replace the work rather than on a paycheck.

The income-multiple shortcut

The shortcut many people hear is to multiply annual income by 10 to 12. For Dale, who we will say earns $70,000 a year, that lands somewhere between $700,000 and $840,000 of coverage. It is quick, easy to remember and a fine place to start a conversation.

The trouble is that a multiple ignores your actual life. It treats a thirty-year-old with a new mortgage and a newborn the same as a fifty-year-old with a paid-off home and grown kids. Think of it as a rough fence line, not the survey, and then check it against the line-by-line math.

The DIME method, line by line

DIME stands for Debt, Income replacement, Mortgage and Education, and you add the four pieces together. Here is how it works for our pretend Wise County family.

Debt. Add up everything owed besides the house, such as the truck note, credit cards and any personal loans. Say Dale and Marisol owe $30,000 across those, so that is the first block.

Income replacement. Multiply annual income by the number of years until your youngest child is independent. If the youngest is 8 and independence is around 18, that is 10 years, so $70,000 times 10 gives $700,000.

Mortgage. Use the remaining loan balance, since paying it off removes the family's biggest monthly obligation. If the balance is $240,000, that is the third block.

Education. Estimate what you want to set aside for college or trade school for each child. For two kids at $60,000 each, that block is $120,000.

Added together, that is $1,090,000 before subtracting anything, which happens to sit above the multiple shortcut. That is the point of doing the math, because it uses your own numbers instead of a rule of thumb. The amount only helps if it reaches the right people, so beneficiary mistakes such as an outdated name or a missing backup are worth fixing when you set up a policy.

What to subtract before you buy

Now take away what the family already has earmarked for these same needs. Savings set aside for the mortgage or for college can reduce the totals above, and so can other money you truly intend to use that way. Be honest with yourself here, because an emergency fund that is already spoken for should not be counted twice. The goal is a number you trust, not the biggest or smallest one.

Check employer group life too, which is coverage offered through a job and often worth only one or two times salary. It usually ends when the job does, so count it as a bonus while it lasts, not as the foundation. If Dale has $70,000 of group life at work and the family has $20,000 earmarked, the gap shrinks from $1,090,000 to about $1,000,000.

Matching the term to the need

Term life insurance covers a set stretch of years, such as 10, 20 or 30, and pays only if death happens during that stretch. The need we just calculated does not stay the same size. As the mortgage pays down and the kids launch, the number the family needs gets smaller.

Many families match the term to their longest obligation, often the mortgage or the years until the youngest is on their own. Some layer more than one term so the coverage steps down as the need does. Which setup fits depends on the household, and it is worth sketching on paper before you apply. A little planning now can keep you from paying for more years than you need.

Where the number meets underwriting

Underwriting is the carrier's review process before it offers a policy. The amount you apply for is checked against your income and your need, which is called financial underwriting, so a number far beyond what the math supports may not be approved. The final offer and your rate class, the pricing group a carrier places you in, depend on medical underwriting, which looks at your health history, and on the carrier itself. No figure in this article is a quote.
