How much life insurance do I really need? (DIME method, 2026)
The short answer: most people are under-insured by 30–60%. The "10× your income" rule is fine if you don't have kids, debt, or a mortgage. If you have any of those, you need a real number — and the DIME method is the simplest way to get one. This article walks through it with real Florida-family numbers.
TL;DR — the 60-second version
- Calculation: Add your debts, multiply your income by years to replace, add your mortgage balance, add education costs per child. Subtract liquid savings + existing life insurance + accessible retirement accounts.
- Typical Florida family (married, 2 kids, $75K income, $220K mortgage): coverage need around $1.4M.
- Cost reality: A healthy 35-year-old non-smoker can buy $1M of 20-year term coverage for under $40/month from an A-rated carrier.*

Why "10× your income" is a bad starting point
The 10× rule has been around since the 1970s, when nobody had student loans, college was 8% of today's cost, and most families had one earner with a defined pension. None of that's true now.
Try it on a real example: a 35-year-old Florida couple, both working, two kids, $75,000 in combined after-tax income, $220,000 left on the mortgage, $15,000 in non-mortgage debt, $50,000 saved across 401k and emergency fund. The 10× rule says they need $750,000 of life insurance.
The DIME method (which we'll walk through next) says they actually need closer to $1,410,000. That's an 88% gap. If the primary earner dies, the family is fine for a few years on the $750K — then they hit a wall when the mortgage balance still exists, the kids hit college, and the surviving parent has to figure it out alone.
The DIME method, step by step
DIME stands for: Debts + Income (replacement) + Mortgage + Education. Then subtract what you already have. That's it.
D — Debts
Add up everything you owe that isn't the mortgage: credit cards, car loans, student loans, medical debt, family loans, business debt that's personally guaranteed. The reason for the calculation: when you die, that debt doesn't disappear — your estate has to pay it from whatever's available. If you don't carry enough life insurance to cover it, your family inherits a smaller estate (or, with co-signed debt, the actual obligation).
Sample family: $15,000 in non-mortgage debt.
I — Income replacement
Multiply your annual after-tax income by the number of years your family needs the money to last. Common rules of thumb:
- 10 years if you have no kids and a working spouse with their own income.
- 15 years if you have school-age kids and a partner who works.
- 20 years if you have young kids and a partner who doesn't work, or whose income alone wouldn't sustain the household.
The "after-tax" detail matters. Life insurance proceeds are received tax-free in almost all cases (IRC §101(a)), so you only need to replace what you actually take home — not your gross.
Sample family: $75,000 × 15 years = $1,125,000.
M — Mortgage
Your remaining mortgage balance. Including this means your family can pay off the house — they don't have to keep making the monthly payment, and they have full equity to draw on if they decide to sell, downsize, or rent it out.
Some advisors argue you should only include enough to cover the monthly payment for X years (using lower-cost term-only "mortgage protection" insurance). My take: just bake it into your DIME number. Term insurance is cheap; a separate "mortgage protection" policy from a less-rated carrier is usually worse on price and benefits.
Sample family: $220,000 mortgage balance.
E — Education
Estimate future education costs per dependent. As of 2026:
| Education path | Total 4-year cost (approx.) |
|---|---|
| Florida public university (in-state, including living expenses) | $80,000 – $110,000 |
| Out-of-state public | $140,000 – $200,000 |
| Private university | $220,000 – $320,000 |
| Trade school / community college | $30,000 – $60,000 |
If you're not sure, $100,000 per child is a reasonable middle-ground number for a Florida-resident family planning on in-state public schools.
Sample family: 2 kids × $100,000 = $200,000.
Subtract what you already have
Add up:
- Liquid savings (checking, savings, brokerage accounts your family could access).
- Existing life insurance (employer-provided + any individual policies).
- Retirement accounts your beneficiaries can access (401k, IRA, Roth IRA — these all pass to named beneficiaries outside probate).
Note: Don't double-count. If a chunk of your retirement is already designated for your spouse's retirement (not as a death benefit), don't count it as a death-benefit offset.
Sample family: $50,000 in liquid + retirement.
Putting it together
| Component | Amount |
|---|---|
| D — Debts | $15,000 |
| I — Income replacement ($75K × 15) | $1,125,000 |
| M — Mortgage | $220,000 |
| E — Education (2 × $100K) | $200,000 |
| Gross need | $1,560,000 |
| Subtract: liquid + retirement | −$50,000 |
| Net coverage need | $1,510,000 |
Round up to $1.5M of 20-year term coverage for the family. For a healthy 35-year-old non-smoker, that's typically $50–$70/month per parent from an A-rated carrier.* Both parents covered: $100–$140/month total. About the cost of a basic gym membership.
Reality check: If $100/month feels like a lot to commit to, it'll feel like nothing compared to what your family faces if you don't have coverage. Most people who "can't afford" life insurance are spending more on coffee, takeout, or streaming services than the policy would cost.

Stay-at-home parent
If one parent doesn't earn income but provides full-time childcare and household management, they still need life insurance. Use the cost of replacing what they do — typically $40,000–$70,000/year for childcare, household labor, and the surviving partner's lost time from work — as the "I" input. So a stay-at-home parent of two young kids might still need $700,000–$1,000,000 of coverage. Most carriers will write up to roughly the working spouse's coverage amount without question.
Single, no dependents
If you have no kids, no spouse, no co-signed debt, and your retirement is funded — you might not need any life insurance. The exceptions: business partnerships (key-person coverage), student loans your parents co-signed, or a strong desire to leave a charitable bequest. Otherwise, the DIME math comes out near zero, and that's fine.
Self-employed or commission-based income
Use a 3-year average of after-tax income, not your best year. Life insurance underwriters do the same thing. Don't try to gain coverage based on a peak year — the carrier will likely re-rate the policy if your tax returns don't support it.
Special-needs dependent
The DIME number isn't enough. You'll likely want a Special Needs Trust funded by life insurance, structured so the dependent doesn't lose Medicaid/SSI eligibility. This is a case where you should work with both an insurance agent and an estate-planning attorney — not just one.
Business owner
DIME covers your family. It does not cover business obligations: SBA loan personal guarantees, partner buy-sell funding, key-person coverage. Those are separate calculations and separate policies. Talk to me if any of those apply.
Term vs whole life — which one for the DIME amount?
Almost always term insurance. Reasons:
- Cost: term is roughly 10–15% the cost of whole life for the same coverage amount.
- Need has a time horizon: the reason you need DIME-level coverage (kids growing up, mortgage paying down, retirement accumulating) is finite. By the time the term policy expires, your DIME need has dropped significantly.
- "Buy term and invest the difference": the math holds for most people. The premium difference between term and whole life, invested in a target-date retirement fund, almost always beats the cash-value growth in whole life.
Whole life and IUL have legitimate uses — high-income people who've maxed out 401k/IRA contributions and want additional tax-advantaged growth, families with estate-tax concerns, business owners using cash value as collateral. But for "I want to make sure my family is OK if something happens to me," term is the answer.
Recalculate at major life events
Recalculate when:
- You get married or divorced
- You have a new child
- You buy a house or refinance
- Your income changes by more than 25%
- Your spouse's career situation changes significantly
Otherwise, every 3 years. And remember: if you over-buy slightly, the cost is minimal. If you under-buy, the cost is borne by your family for decades. Round up.
A note on "free quotes" online
Most online quote tools optimize for clicks, not accuracy. They'll show you the cheapest possible rate (which assumes "Preferred Plus" health classification — a category fewer than 10% of applicants actually qualify for), and then call you to upsell. The quote you actually get is usually 30–60% higher than the teaser rate.
I'll quote you at the rate class you'll most likely qualify for based on a 5-minute health conversation. Less optimistic, more accurate. If your underwriting comes back better than expected, your premium goes down, which is a nice surprise — never worse than promised.
