If you search for life insurance advice online, you'll find the same answer almost everywhere: buy ten times your annual income. It's clean, it's memorable, and it's a perfectly fine starting point — but it's not an answer. It ignores your debts, whether you own a home, how many kids you have, how many years of income your family would actually need to replace, and what you already have saved.
The real answer takes about five minutes of honest math. Here's the framework we use with every client who walks through the Lucid Brokers funnel.
Start with the DIME method: add up your Debts, 5–10 years of Income replacement, your outstanding Mortgage balance, and projected Education costs for any children. Subtract what you already have in liquid savings and existing coverage. The number you're left with is the gap a life insurance policy should fill.
Why the "10x income" rule falls short
The 10x rule was designed for speed, not accuracy. It assumes every 35-year-old earning $80,000 needs the same amount of coverage, which is obviously wrong. Two people making the same salary can have wildly different needs:
- Person A: renter, no kids, partner with their own income. A smaller policy is probably fine.
- Person B: homeowner with a $400,000 mortgage, three kids under ten, stay-at-home spouse. 10x income isn't close to enough.
The rule also ignores the biggest variable in the equation: how long your family needs support. A 28-year-old with a newborn needs roughly 20 years of runway before the kid is financially independent. A 55-year-old with grown children and a nearly-paid-off home needs much less.
A better framework: the DIME method
DIME stands for Debt, Income, Mortgage, and Education. It was popularized by consumer advocates because it forces you to think in terms of actual obligations rather than a multiplier. Here's how to run it.
Coverage = D + I + M + E − existing assets
- D — Debt (excluding mortgage)
- Credit cards, student loans, auto loans, medical debt, personal loans. Anything a surviving spouse or estate would inherit.
- I — Income replacement
- Your annual after-tax income × the number of years your family would need support. Most brokers recommend 5 to 10 years, depending on kids' ages and your spouse's earning power.
- M — Mortgage balance
- The remaining principal on your home loan. The goal is for your family to be able to stay in the house without scrambling.
- E — Education costs
- Roughly $100,000–$250,000 per child for a four-year degree in 2026 dollars, depending on public vs. private expectations. Drop this line if your kids are grown.
Then subtract what you already have: liquid savings earmarked for your family, the face value of any existing life insurance (including employer group coverage), and any other assets that would pass immediately and without taxes.
Three real examples
Let's run the numbers on three common situations. All examples use rough assumptions for illustration — your own figures will vary.
Example 1 — Single parent, two kids
| D — Debt | $18,000 |
| I — Income × 10 years (after tax) | $500,000 |
| M — Mortgage | $0 |
| E — Education (2 kids × $125k) | $250,000 |
| − Existing savings & group life | −$40,000 |
| Recommended coverage | $728,000 |
Most brokers would round up and suggest a $750,000 20-year term policy — long enough to get both kids through college.
Example 2 — Dual-income couple, no kids yet
| D — Debt | $22,000 |
| I — Higher earner's income × 5 years | $400,000 |
| M — Mortgage | $310,000 |
| E — Education | $0 |
| − Existing savings | −$35,000 |
| Recommended coverage (each) | $697,000 |
Each spouse should carry roughly $700,000. A 30-year term makes sense here so the policy stretches through future kids' college years if they decide to have children.
Example 3 — Empty nesters, mostly paid-off home
| D — Debt | $5,000 |
| I — Income × 3 years | $220,000 |
| M — Mortgage | $65,000 |
| E — Education | $0 |
| − Existing savings & retirement | −$180,000 |
| Recommended coverage | $110,000 |
At this stage, a smaller 10-year term or even a final expense whole life policy is often the right call. The goal shifts from income replacement to covering remaining debts and final expenses.

DIME is a floor, not a ceiling. Consider buying above the number if any of these apply:
- You have a special needs dependent who will need support beyond age 18.
- You're the primary earner by a large margin — the formula's "5–10 year" default may not give your spouse enough runway.
- You have a business with key-person risk — you may need a separate policy so the business can survive your absence.
- You want to leave a legacy — intentional inheritance, charitable giving, or estate tax planning are valid reasons to buy more coverage.
When you might need less
You may not need as much coverage as the formula suggests if:
- You're already close to financial independence and your existing investments can replace your income.
- Your spouse earns a comparable income and your kids are older, shrinking the income-replacement gap.
- You're buying a second policy to top up existing coverage — don't double-count what you already have.
What about "can I have too much"?
Yes, in a sense. Insurance carriers apply something called insurable interest and won't let you stack unlimited coverage on one life. Most will cap you around 20–30× your annual income for working adults, and stay-at-home parents are usually limited to a multiple of the working spouse's income. Beyond that, premiums become wasted money — you're paying for protection your family doesn't actually need.
Lock in your number while you're healthy
Here's the piece most articles bury: life insurance gets more expensive every birthday, and much more expensive if your health changes. A 32-year-old in great health can usually lock in a $750,000 20-year term policy for around $30–$45 a month. That same person at 42 with slightly elevated blood pressure might pay double — and someone diagnosed with a chronic condition may find they can't qualify at all.
Running the DIME formula is a one-time exercise. Buying the policy it tells you to buy is a one-week exercise. The longer you wait, the more it costs — and the more risk your family carries in the meantime.
Putting it all together
A defensible coverage number takes five minutes of honest math, not a multiplier. Run the DIME formula, subtract what you already have, and use the result as your target. Then shop quotes from multiple carriers — not just one — and pick the term length that matches your actual obligations (usually 20 or 30 years for parents, 10–15 for empty nesters).
If you'd rather skip the spreadsheet and just see real quotes for your situation, that's exactly what Lucid Brokers is built for. You'll see instant rates from multiple A-rated carriers in under two minutes, and you can apply online the same day.
