The "10× your income" rule is a starting point, not an answer. The correct life insurance coverage for your family depends on your debts, your income, your mortgage, your kids' ages, and how many years your family would need replacing your paycheck. Here's the exact 2026 calculator that gets you a real coverage number in under five minutes.
Why the Right Coverage Amount Matters
Underinsuring is the most common and most expensive mistake in personal finance. A policy that's too small leaves your family exposed to a mortgage they can't pay, college plans they can't fund, or a forced lifestyle downgrade at the worst possible moment.
Overinsuring isn't great either — but it's a much smaller problem. You're paying $50–$200/year extra for the wrong amount. Underinsuring by $300,000 means your family is exposed to that shortfall at the exact moment the policy is supposed to pay out.
The goal isn't "as much as I can afford." The goal is as much as my family needs to recover financially if I die tomorrow. Those are very different numbers — and the second one is smaller than most people think, once you subtract what you already have.
The 2026 Coverage Calculator (Step-by-Step)
You need to know five things about your family, and a sixth about you. Each is a number. Add the first five, subtract the sixth, and you have your coverage gap.
Coverage Need = (Income to Replace × Years) + Debts + Final Expenses + Education − Existing Assets
That's the example. Yours will look different. For most two-earner or single-earner households with kids, the answer lands between $500,000 and $2,000,000. Younger parents with little debt often need $750,000–$1,250,000. Older empty-nesters with paid-off mortgages sometimes need only $250,000–$500,000 for final expenses and spouse support.
The Income Replacement Rule That Beats "10×"
The "10× your income" rule is a shortcut. It's better than nothing, but it dramatically overshoots for many households and undershoots for others. A better rule:
Replace 70–80% of your take-home pay for the years your family needs it.
Why 70–80% and not 100%? Because the IRS taxes life insurance death benefits, but a $1M policy typically leaves the family with effectively $950K–$980K after estate and probate fees depending on state. And your family won't need to replace 100% of your income — federal tax brackets shift, your spouse may return to work part-time, and Social Security survivor benefits cover young children until they're 18.
For a couple in their mid-30s with a $90,000 household income and two young children, that's replacing $63,000–$72,000/year for 18 years (until the youngest hits 22) — which equals $1.1M to $1.3M in pure income-replacement coverage.
Three Real Coverage Examples
| Family | Income & Assets | Debts & Obligations | Recommended Coverage |
|---|---|---|---|
| 35-year-old, married, 2 kids (ages 4 and 2), homeowner | $95K income, $300K employer life, $80K savings | $340K mortgage, $35K auto + student loans | $1,250,000 (20-year level term) |
| 42-year-old, married, 1 teenager, homeowner with paid-off mortgage | $125K income, $200K employer life, $200K investments | No mortgage, $15K auto loan, $50K college funding | $650,000 (15-year level term) |
| 52-year-old, married, empty nest, paid-off home | $140K income, no employer life, $1.4M retirement assets | No debts, $30K final expenses, $200K spouse support | $400,000 (10–15 year term or small whole life) |
Adjustments for Stay-at-Home Parents, Kids' Ages, and Debt
If one parent stays at home
Their economic contribution (childcare, household management, transportation, cooking) often equals $50,000–$90,000/year if replaced by paid services. The surviving spouse would need to absorb that cost or work less, which is itself a real income loss. A stay-at-home parent's economic value justifies a meaningful policy — typically $250,000–$500,000 for a 20-year term.
If your kids are older
The shorter the runway until they're independent, the less income-replacement coverage you need. With teenagers close to college age, focus the policy on college funding specifically rather than income replacement. A $200,000 10-year term policy is often the right answer.
If you have high-interest debt
Credit card balances, personal loans, and private student loans are lethal stress points. Clearing them at death — both for the surviving spouse and for any co-signer — is one of the highest-ROI uses of life insurance. Customer co-signed private student loans get discharged at death; federal loans do too. But a private student loan co-signed with your spouse is the spouse's full responsibility after your death.
If your employer offers free life insurance
Most employer group life insurance is 1×–2× salary, often at no cost to you. Take it. Subtract it from your gap calculation. If your group policy maxes out (most do at $50K–$300K) and you need a million-dollar policy, you'll need a private term policy for the rest.
How Term Length Fits With Coverage Amount
Coverage amount and term length are linked but not identical decisions. The right pairing:
- 20-year level term is the workhorse for families with young kids. Locks in a fixed premium for 20 years, by which time the kids are grown and the mortgage is largely paid down.
- 30-year level term works when you have very young kids, a large mortgage, or want to lock in the longest runway. Premiums are higher — typically 30–40% above 20-year level term for the same coverage.
- 15-year or 10-year term suits younger single earners, divorced parents funding college, or empty-nesters refinancing to a smaller policy after a major liability disappears.
- Convertible term (a feature, not a separate policy) lets you convert some or all of the term coverage to permanent life insurance later without re-underwriting. Worth taking if you might want to lock in coverage past the term expiration.
5 Common Mistakes When Sizing Coverage
- Buying the cheapest policy. Premium matters, but not as much as leaving $400K of debt to your spouse.
- Including your home equity twice. Your spouse won't get a $400,000 inheritance plus a $400,000 life insurance payout to pay off the same $400,000 mortgage. The mortgage pays off; the spouse keeps the equity.
- Forgetting college. Funding four years at a state school costs roughly $120,000 per child today. Two kids = a quarter-million dollars of additional reason to size the policy correctly.
- Ignoring your spouse's earning capacity. If your spouse earns $150K/year and could return to work full-time after a year of grief, you don't need to replace 100% of your income for 20 years. Maybe 60–70% until kids are stable.
- Forgetting to revisit the policy every 3–5 years. Big life changes — divorce, new kids, paid-off mortgage, significant raises — should trigger a coverage recheck. Most policies are sized at one moment in life and never revisited.
