"Get 10 times your salary" is the most repeated piece of life insurance advice on the internet, and it's mostly wrong. It ignores whether you have a mortgage, how many kids you're supporting, how close you are to retirement, and what you've already saved. A 28-year-old with a newborn and a 30-year mortgage needs a very different number than a 55-year-old with a paid-off house and grown children — even at identical salaries. Here's how to actually calculate it.
The DIME Method: A Real Formula
Financial planners use DIME — Debt, Income, Mortgage, Education — to build a number grounded in your actual obligations instead of a salary multiple.
Worked Example: The Ramirez Family
Meet a hypothetical family: two parents, ages 34 and 36, two kids ages 4 and 7, household income $95,000 from the primary earner, $310,000 remaining on the mortgage, $18,000 in car loans and credit cards, and $40,000 already saved in retirement and college accounts.
| DIME Component | Calculation | Amount |
|---|---|---|
| Debt (non-mortgage) | Car loans + credit cards | $18,000 |
| Income replacement | $95,000 × 15 years (until kids independent) | $1,425,000 |
| Mortgage | Remaining balance | $310,000 |
| Education | 2 kids × $60,000 est. college cost | $120,000 |
| Subtotal | Sum of above | $1,873,000 |
| Less existing savings | Retirement + 529 accounts | −$40,000 |
| Target coverage | $1,833,000 |
That's nearly 19x salary — far above the generic "10x" rule — because this family has a large mortgage, two kids with a long runway to independence, and future college costs baked in. A childless couple with no mortgage and both incomes covering only their own expenses might need less than 5x salary.
Why "Years Needed" Is the Variable That Matters Most
The income-replacement piece is usually the largest single number in the formula, and it hinges entirely on how many years of income you're replacing. Use the age of your youngest child (until they're financially independent, typically 18-22) as a reasonable anchor, or your own years until planned retirement if there are no dependents. Shaving this from 15 years to 10 years in the Ramirez example would cut coverage need by roughly $475,000 — a huge swing from one assumption.
Term vs. Whole Life: The Cost Difference Is Enormous
Term life insurance covers you for a fixed period (10, 20, or 30 years) and pays out only if you die during the term. Whole life bundles permanent coverage with a cash-value investment component — and costs dramatically more.
- Term: A healthy 35-year-old can get $500,000 of 20-year term coverage for roughly $25-$35/month.
- Whole life: The same $500,000 of permanent coverage often runs $400-$500+/month — 10-15x the cost.
For most families, term life covering the years until the mortgage is paid off and kids are independent delivers far more protection per dollar. The savings from choosing term can instead be invested directly, typically outperforming a whole life policy's internal cash-value growth.
When to Recalculate
Your number isn't static. Recalculate after a major mortgage refinance, a new child, a significant raise, paying off your house, or your kids becoming financially independent — each of these can swing your target by six figures in either direction. Many families simply set coverage once at age 30 and never revisit it, ending up either underinsured after a second child or paying for coverage they no longer need after the mortgage is gone.
