The 10x income rule is a starting point, not a finish line. Here is how DFW families should calculate the right number given local home prices, college costs, and income.
The 10x rule — and why it is not enough
Most agents will tell you to buy 10 times your annual income. If you earn $80,000, they say buy an $800,000 policy. That math is a starting point, not an answer.
The 10x rule was designed to be simple, not accurate. It ignores your mortgage balance, your actual debts, how many children you have, how old they are, and what college will cost by the time they attend. A better approach takes about 10 minutes and produces a number that actually fits your household.
The DIME method for DFW families
DIME stands for Debt, Income, Mortgage, and Education. Add those four numbers together and you have a coverage target grounded in your actual obligations.
- Debt: Every balance you carry — car loans, credit cards, student loans, personal loans. Not the minimum payment, the full balance.
- Income: Your annual income multiplied by the number of years your family needs to be supported. A common target is 10–15 years, depending on the age of your youngest child.
- Mortgage: Your current outstanding mortgage balance, not the original loan amount.
- Education: The projected cost of college for each child. Average four-year public university cost in Texas is currently around $88,000 all-in. Private runs $180,000–$240,000.
A DFW household earning $90,000 with a $380,000 mortgage, two young kids, $25,000 in other debt, and 12 years of income to replace lands at roughly $1.5 million in coverage. A standard 10x policy would leave that family $700,000 short.
DFW home prices change the math
The median home price in the Dallas-Fort Worth metro sits around $390,000. In Frisco, Southlake, or Flower Mound, you are more likely looking at $550,000–$700,000. That mortgage balance is typically the largest single item in a DIME calculation, and it is larger in North Texas than in most of the country.
If you bought your home in the last three years with a conventional loan at current rates, the mortgage payoff alone may justify a $400,000–$600,000 policy before you account for anything else. This is why policies that were adequate five years ago — before the DFW market ran up — may now be undersized for families who purchased or refinanced recently.
How many years of income to replace
The right number of income-replacement years depends on how old your youngest child is and what your spouse's earning capacity looks like. A two-parent household where both work and earn similar incomes needs less coverage than a household where one spouse left the workforce to raise children.
A practical rule: add income replacement years until your youngest child is 25 — old enough to be financially independent. For a family with a 2-year-old, that is 23 years. For a family with a 10-year-old, that is 15 years.
If your surviving spouse has no established career and would need time to re-enter the workforce, add 2–3 years on top of that estimate to account for the transition.
When to revisit your coverage
A policy you bought at 30 may be the wrong size at 38. Life changes faster than most people update their insurance. Review your coverage after any of these events:
- A new child or dependent joins the household
- You purchase a home or refinance into a larger mortgage
- Your income increases significantly
- A spouse leaves the workforce
- You take on substantial new debt
- A parent or sibling becomes financially dependent on you
Coverage that is too low is an obvious problem. Coverage that is too high is a waste of premium dollars. Getting the number right matters in both directions.
Frequently asked questions
Is the 10x income rule accurate for Dallas-Fort Worth residents?
Not for most DFW families. The 10x rule ignores your mortgage balance, which in the DFW metro often exceeds $350,000. The DIME method — Debt, Income, Mortgage, Education — produces a more accurate number. For many DFW households, the right coverage is 12–15x income once the mortgage and education costs are factored in.
How much does a $500,000 term life policy cost in Texas?
A healthy 35-year-old non-smoker in Texas can get a $500,000 20-year term policy for roughly $25–$35 per month. Rates vary based on health history, tobacco use, and the carrier. At 45, that same coverage typically runs $55–$80 per month.
Does my employer-provided life insurance count toward my coverage need?
It can, but with one significant caveat: employer-provided coverage ends when you leave the job. If your coverage number is $1.2 million and your employer provides $200,000, you need at least $1 million in personal coverage that you own and control regardless of your employment status.
How often should I review my life insurance coverage?
Every 3–5 years at minimum, or immediately after a major life event — a new child, a home purchase, a significant income change, or a spouse leaving the workforce. Policies do not self-adjust when your life changes.
