Key takeaways
- A quick rule of thumb is 10 times your income, but a needs-based calculation is far more accurate.
- The DIME method adds Debt, Income replacement, Mortgage and Education, then you subtract savings and existing coverage.
- In our example, a $80,000 earner with two kids needs roughly $1.2 million to $1.5 million of term coverage, not $800,000.
- Term life is cheap for healthy young buyers: a 20-year, $500,000 policy averaged about $213 a year for a 30-year-old man as of Oct. 1, 2026.
Most people need enough life insurance to replace their income for the years their family depends on it, pay off the mortgage and other debts, and cover big future costs like college. For a typical parent, that often lands somewhere between 10 and 15 times annual income. The exact number comes from a simple formula you can run in about 15 minutes.
Getting this right matters. In the 2026 Insurance Barometer Study from LIMRA and Life Happens, only 52% of Americans said they own life insurance, and nearly 100 million said they’re uninsured or underinsured. Many people also guess wrong on price: 40% overestimated what a basic 20-year term policy would cost them.
Below, you’ll find three ways to figure out how much life insurance you need, a full worked example, and the mistakes that leave families short.
Who needs life insurance (and who doesn’t)
Life insurance exists to replace money that would disappear if you died. You likely need it if someone depends on your income or your unpaid work:
- Parents of minor children, including stay-at-home parents
- Spouses or partners who share a mortgage or rely on two incomes
- People who co-signed private student loans or other debts
- Business owners whose partners or lenders depend on them
- Adults supporting aging parents or a family member with special needs
You may not need any if you’re single with no dependents, or if you’re retired and your savings, pension and Social Security would fully support a surviving spouse. In those cases, enough cash to cover final expenses may be all you need.
Method 1: The income-multiple rule of thumb
The fastest estimate is 10 times your annual income. Some planners add $100,000 per child for college costs. If you earn $80,000, that’s $800,000, or $1 million with two kids.
It’s a reasonable starting point, but it has blind spots. It ignores how big your mortgage is, how much you’ve already saved, any coverage you get through work, and how many years your family actually needs support. A 28-year-old with a newborn and a 55-year-old with grown kids shouldn’t use the same multiple.
Method 2: The DIME formula
DIME is a more complete checklist. You add four buckets:
- D – Debt and final expenses: Car loans, credit cards, personal loans and other non-mortgage debt, plus funeral costs. The National Funeral Directors Association put the 2023 national median cost of a funeral with viewing and burial at $8,300 ($6,280 with cremation).
- I – Income: Your annual income times the number of years your family would need it, usually until your youngest child is independent.
- M – Mortgage: The remaining balance, so your family can stay in the home.
- E – Education: What you want to set aside for your kids’ college or trade school.
Then subtract what’s already available: liquid savings, non-retirement investments, college funds and any existing life insurance, including group coverage from your employer. Don’t count your home or car, and generally don’t count retirement accounts your spouse will need later.
Worked example: how much coverage does this family need?
Meet a hypothetical 35-year-old parent who earns $80,000 a year. They have two kids (ages 4 and 7), a $280,000 mortgage balance, a $15,000 car loan, $40,000 in savings, and a workplace life policy worth one year’s salary ($80,000). They want 15 years of income replacement, until the youngest finishes high school and a bit beyond, and $50,000 per child for college.
| DIME item | Calculation | Amount |
|---|---|---|
| Debt + final expenses | $15,000 car loan + $15,000 funeral and settling costs | $30,000 |
| Income replacement | $80,000 × 15 years | $1,200,000 |
| Mortgage | Remaining balance | $280,000 |
| Education | $50,000 × 2 kids | $100,000 |
| Total need | $1,610,000 | |
| Minus savings | −$40,000 | |
| Minus workplace coverage | −$80,000 | |
| Coverage to buy | $1,490,000 |
That’s nearly double the $800,000 the 10x rule suggests. The difference comes mostly from the mortgage and the full 15 years of income.
A more precise refinement
The DIME income line assumes your family spends the payout and earns nothing on it. In reality, a lump sum invested conservatively keeps earning while it’s drawn down. If the money earns about 4% a year, a lump sum of roughly $889,000 (not $1.2 million) could fund $80,000 a year for 15 years. At 3%, you’d need about $955,000.
Swap that in, and the need drops to about $1.18 million after subtracting savings and workplace coverage. So a reasonable target for this family is $1.2 million to $1.5 million. Picking the higher end builds in a cushion for inflation, which steadily raises the cost of living over 15 years.
Don’t lean on workplace coverage: Group life insurance usually ends when you leave the job, and it’s often only one or two times your salary. Treat it as a bonus, not your plan. Many people buy enough individual coverage to be protected even if they change employers.
Method 3: A full needs-based plan
If your situation is complicated, go line by line instead of using DIME’s four buckets. Add up:
- Income replacement, adjusted for what a surviving spouse earns
- Childcare, housekeeping and other services a stay-at-home parent provides
- Mortgage or rent for the years your family needs housing help
- All other debts and final expenses
- College or other planned costs
- An emergency cushion for the transition (our emergency fund calculator helps size it)
Then subtract liquid assets and existing coverage. Social Security survivors benefits can also help minor children and a surviving spouse caring for them, which may reduce what you need from a private policy. Check your estimated benefits in your my Social Security account before you finalize a number.

How much does that much coverage cost?
Term life insurance is usually the most affordable way to buy a large amount of coverage. Here are average annual premiums for a 20-year, $500,000 term policy for healthy nonsmokers (preferred class), as of Oct. 1, 2026, according to NerdWallet’s analysis of quotes:
| Age at purchase | Men (annual) | Women (annual) | Men (monthly) | Women (monthly) |
|---|---|---|---|---|
| 30 | $213 | $182 | ~$18 | ~$15 |
| 40 | $321 | $278 | ~$27 | ~$23 |
| 50 | $810 | $636 | ~$68 | ~$53 |
Two lessons stand out. Buying younger is much cheaper, since premiums climb steeply after 40. And your health matters: smokers and people with certain medical conditions pay more. Your own quote will depend on your age, health, the insurer and the coverage amount, so compare quotes from several companies.
Whole life insurance costs many times more for the same death benefit. For most families who need income replacement, term coverage matches the need better. Our comparison of term vs. whole life insurance walks through when permanent coverage makes sense.
How long should your term be?
Match the term to your longest financial obligation:
- Youngest child’s independence: If your youngest is 4, a 20-year term covers them through about age 24.
- Mortgage payoff: If you have 25 years left on a 30-year loan, a 25- or 30-year term protects the house.
- Retirement: Coverage often matters less once your savings can support a surviving spouse.
You can also ladder policies. Instead of one $1.5 million, 20-year policy, the family above might buy a $1 million, 20-year policy and a $500,000, 10-year policy. Coverage is highest while the kids are young and the mortgage is large, then steps down as those needs shrink, which can lower total premiums.
Common life insurance mistakes
- Relying only on employer coverage. It’s usually too small and can vanish with a job change.
- Skipping coverage for a stay-at-home parent. Replacing childcare, transportation and household work costs real money.
- Buying a term that’s too short. Renewing or buying new coverage later, when you’re older, can cost far more.
- Forgetting to update beneficiaries. After marriage, divorce or a new child, review who’s named. A will doesn’t override a policy’s beneficiary designation. Our estate planning basics guide explains how the pieces fit.
- Naming minor children directly. Insurers generally can’t pay large sums to minors. Many parents name a trust or a custodian instead.
- Guessing instead of calculating. Run the numbers once now, and again after any major life change.
Your next steps
- Total your debts, mortgage balance, savings and existing coverage.
- Run the DIME formula, then refine the income line for investment returns and your spouse’s earnings.
- Choose a term that lasts until your biggest obligations end.
- Get quotes from at least three insurers and apply while you’re healthy.
- Fit the premium into your broader plan. Our step-by-step financial plan guide and checklist of types of insurance you need can help you see the full picture.
Frequently asked questions
Is $500,000 of life insurance enough?
It depends on your income, debts and dependents. For a single parent earning $40,000 with a small mortgage, it may be plenty. For someone earning $80,000 with two kids and a $280,000 mortgage, our example shows a need closer to $1.2 million to $1.5 million.
Should life insurance be 10 times your salary?
Ten times income is a quick starting point, not a rule. It can overstate your need if you have large savings, or understate it if you have a big mortgage, young kids or plans to pay for college. A DIME or needs-based calculation is more accurate.
Does a stay-at-home parent need life insurance?
Usually, yes. If they died, the family would likely pay for childcare, transportation and household help. Add up those costs for the years they’d be needed and use that as the coverage target.
Is life insurance taxable?
Death benefits paid to a beneficiary are generally not subject to federal income tax. Interest earned on a payout that’s held before being paid, or very large estates, can raise other tax issues, so check with a tax professional for your situation.
Can I have more than one life insurance policy?
Yes. Many people combine workplace coverage with an individual policy, or ladder two term policies of different lengths. Insurers will ask about your existing coverage when you apply.
