How Much Life Insurance Do You Actually Need?
Coverage Guide · Life Insurance
The most common answer to "how much life insurance do I need" is a guess dressed up as a rule: "get 10 times your income." It's an easy number to remember, and it's not wrong for everyone, but it isn't a calculation either. It doesn't know if you have a mortgage, young kids, a stay-at-home spouse, or $200,000 already saved. A real number comes from adding up what your family would actually need to replace, not from a single multiplier.
Why the income-multiplier rule falls short
Multiplying your income by some number between 10 and 15 is a reasonable starting guess, and better than nothing. But two people earning the same $80,000 salary can have completely different needs: one has a paid-off house and grown kids, the other has a new mortgage, two toddlers, and no savings yet. The multiplier treats them the same. A proper number treats them differently.
The DIME method: a real calculation
DIME stands for Debt, Income, Mortgage, and Education, the four things most families actually need covered. Add them up and you get a number specific to your situation, not a generic multiple.
| Category | What to add |
|---|---|
| D – Debt | Credit cards, car loans, personal loans, and any other debt besides the mortgage |
| I – Income replacement | Years your family would need your income replaced, times your annual income |
| M – Mortgage | Your remaining mortgage balance, if you want it paid off entirely |
| E – Education | Future college or education costs for your children |
| Total need | Add the four, then subtract existing savings and coverage |
Working through each piece
Debt: add up everything besides the mortgage, credit cards, auto loans, student loans, medical debt. This is money your family would otherwise have to pay off out of savings or your take-home pay.
Income replacement: this is usually the largest number and the one people underestimate. Pick a number of years your family would need your income replaced, often until kids are grown or a spouse could realistically re-enter or grow their own income, then multiply by your annual income. Replacing 15 years of a $70,000 income is $1,050,000, not $700,000.
Mortgage: your current payoff balance, if your goal is for your family to own the home outright rather than keep making payments from your coverage.
Education: a rough estimate per child. In-state public college currently runs somewhere in the $100,000–$120,000 range for four years including room and board; private and out-of-state costs more. You don't need precision here, a reasonable estimate per child is enough.
What to subtract
Once you've added the four categories, subtract what you already have working in your favor:
- Existing life insurance, including any coverage through your employer
- Savings and investments that could be used toward these costs
- A working spouse's income, if it would reasonably cover some of the income-replacement years on its own
A worked example
Take a 34-year-old with a spouse, two young kids, a $280,000 mortgage balance, $15,000 in other debt, and $60,000 saved so far:
| Debt | $15,000 |
| Income replacement (15 years × $75,000) | $1,125,000 |
| Mortgage balance | $280,000 |
| Education (2 kids × ~$110,000) | $220,000 |
| Subtotal | $1,640,000 |
| Less: existing savings | −$60,000 |
| Estimated need | ~$1,580,000 |
That's a meaningfully different number than the quick "10x income" rule would have suggested ($750,000), and it's specific to this family's actual obligations rather than a guess.
When to recalculate
Your number isn't permanent. Worth revisiting after a new baby, a new mortgage or refinance, a significant raise or job change, paying off a major debt, or roughly every few years regardless. Most people set a policy once at a number that made sense at the time and never adjust it, which is how families end up either underinsured or paying for more than they still need.
This is general information, not a personalized recommendation. Your actual number depends on specifics a worksheet can't capture, like health history, other assets, and what "taken care of" means to your family. Our free assessment walks through this with your real numbers in a few minutes.
