How Much Life Insurance Does a Texas Household Actually Need?
The cleanest method for Texas families is obligation-stack: mortgage balance + 10× primary income + $50,000 per child for education + $25,000 final expenses − liquid savings. For a typical Austin household earning $180,000 with two kids and a $400,000 mortgage, that lands at roughly $2.05 million of term coverage. DIME and 10× income are reasonable approximations that get most people in the right neighborhood; obligation-stack matches each dollar of coverage to a specific job.
Three methods compared
DIME (Debt + Income + Mortgage + Education): conservative, used by most carriers as a baseline sanity check. Tends to over-state need for households with significant liquid assets.
Income-multiple (10–15× household income): fast, popular in financial-planning shorthand, ignores asset offsets and obligation-specific timing.
Obligation-stack: most precise. Each dollar of coverage maps to a specific obligation (mortgage, college, income replacement years, final expenses) minus liquid offsets.
A worked example for a Texas household
Household: Austin, two earners ($180k and $90k), two kids (ages 6 and 9), $400,000 mortgage with 23 years remaining, $185,000 in retirement assets, $30,000 cash.
Primary earner ($180k) obligation stack: $400,000 mortgage + $1,800,000 income replacement (10×) + $100,000 education (2 kids × $50k) + $25,000 final expenses − $185,000 retirement − $30,000 cash = $2,110,000 of term coverage needed.
Secondary earner ($90k) obligation stack: $900,000 income replacement (10×) + $25,000 final expenses = $925,000 of term coverage needed. (Mortgage and education already covered by primary earner's policy.)
Recommended structure: primary earner gets a $2M / 20-year term plus a $250k / 30-year term layered (ladder). Secondary earner gets a $1M / 20-year term.
Common mistakes in sizing
Forgetting the stay-at-home spouse. Replacement of childcare and household labor is a real cost — usually $50,000–$80,000 per year for households with school-age children.
Counting illiquid assets (home equity, retirement accounts subject to penalty) as full offsets. They are not. A $400k house cannot pay this month's grocery bill.
Sizing only for the mortgage and not for income replacement. Mortgage is rarely the largest line item.
Buying 10-year term when the youngest child is 8 — leaves a coverage gap during the most expensive teenage years.
Try the numbers yourself
Run your obligation stack and compare to the 10× and DIME methods. If all three are within 20% of each other, you have a reliable number.
If obligation-stack comes out materially lower than 10× income, double-check that you have included full income replacement years (years until youngest child is independent at minimum).
