Most families need enough life insurance to pay off debts and the mortgage, replace the income they would lose until the children are independent, and fund any education goals, minus the savings and coverage they already have. For a typical family with young children that often lands between 10 and 15 times the main earner’s income. Single people with no dependents may need little or none.
Getting the number roughly right matters. LIMRA’s 2026 Insurance Barometer Study found that 38% of US adults, about 92 million people, say they need life insurance or more of it. Cost is the main reason they hold back, yet about three in four people overestimate what a policy costs. Use the calculator below to find your figure, then read how each part works and three worked examples.
Calculate your number
Life insurance needs calculator (DIME method)
Add up what your family would need to pay off and replace, then subtract what you already have. Fill in your own figures; the defaults are an example family.
College default: four years of average in-state tuition and fees at a public four-year college in 2025-26 ($11,950 a year, College Board), without room and board. Final expenses default: NFDA median for a funeral with viewing and burial. Social Security survivor benefits are not included and can reduce the need. An estimate for guidance only.
How the DIME method works
DIME stands for Debt, Income, Mortgage and Education. It is popular because it is easy to understand and forces you to think about each obligation separately, instead of picking a round number.
D: Debts and final expenses
Include car loans, credit cards and personal loans your family would have to keep paying. Leave out federal student loans, which are discharged when the borrower dies, but include private student loans, especially if a parent co-signed. Add final expenses: the National Funeral Directors Association’s latest figures put the median funeral with viewing and burial at about $8,300, and with cremation at about $6,280.
I: Income
Multiply your yearly income by the number of years your family would need it. A common choice is until your youngest child turns 18, or until your partner retires. You can use a lower figure than your gross income, since your own spending and taxes disappear, but many families prefer to keep a margin for inflation and unexpected costs.
M: Mortgage
Paying off the mortgage lets your family stay in the home without your income. If you would rather they keep the loan and the payments, you can leave this out and count the payments as part of the income figure instead, but do not count it twice.
E: Education
The College Board puts average published tuition and fees for 2025-26 at $11,950 a year at a public four-year college for in-state students, $31,880 for out-of-state students and $45,000 at private nonprofit colleges. Four years of in-state tuition is about $47,800 per child, before room, board and books.
Minus what you already have
Subtract existing life insurance and savings your family could actually use. Treat coverage from work with caution: it is often only one or two times salary and usually ends when you leave the job. Social Security survivor benefits can also help: they can be paid to unmarried children under 18 (or up to 19 if still in high school) and to a surviving spouse caring for your child, according to the Social Security Administration.
Three worked examples
Final expenses: $8,300
Income, mortgage, education: $0 (no one depends on the income)
Income: $85,000 × 14 years (until the youngest is 18) = $1,190,000
Mortgage: $280,000
Education: 2 × $47,800 = $95,600
Minus group life ($170,000) and savings ($30,000)
Final expenses: $8,300
Education is covered by the earning partner’s policy
The second example shows why rules of thumb can fall short. The family’s real obligations are well above 10 times income, mainly because of the long income gap and the mortgage. The third shows the opposite mistake: a parent with no salary still has an economic value that would cost money to replace.
Rules of thumb compared
| Method | Good for | Watch out for |
|---|---|---|
| 10x income | A quick first estimate | Ignores debts, the mortgage and your children’s ages |
| DIME | Families with a mortgage and children | Can overstate needs if savings are large |
| Income replacement | Main earners with young children | Leaves out one-off costs like college |
| Final expenses only | Single people with no dependents | Too little if anyone relies on you |
One big policy or two smaller ones?
Your need is usually highest while your children are young and your mortgage is large, then falls each year. Some families match this by “laddering”: for example, a 30-year policy for part of the amount and a 20-year policy for the rest, so coverage steps down as the need does. It can cost less than one large 30-year policy, but it means managing two policies. Ask for quotes both ways.
Whichever you choose, term life is the usual tool for covering these needs at the lowest cost. If you are weighing it against permanent coverage, see term vs whole life insurance.
Mistakes that leave families short
- Relying only on cover from work. It may be too small and disappears if you change jobs or are laid off.
- Forgetting the stay-at-home parent. Childcare and household work cost money to replace.
- Not reviewing after big changes. A new baby, a bigger mortgage or a pay rise all change the number.
- Buying a term that is too short. If your youngest is 2, a 10-year policy ends while they are still a child.
- Overestimating the cost. A healthy 30-year-old can often buy $500,000 of 20-year term for well under $50 a month. Check typical prices in life insurance cost by age.
Frequently asked questions
Is 10 times my salary enough life insurance?
It is a reasonable starting point, but it is often too little for families with young children and a mortgage, and too much for someone with no dependents. A needs-based method like DIME gives a more personal answer.
Do I need life insurance if I am single?
Often not much, unless someone depends on you financially, you have co-signed private debts, or you want to cover your funeral so your family does not have to. Buying while young and healthy can also lock in a low price if you expect to have dependents later.
How often should I review my coverage?
Every few years, and after any major life event: marriage, a new child, buying a home, a big change in income or paying off a large debt.
Can I get this much coverage without a medical exam?
Some insurers offer no-exam term policies up to $1 million or more for healthy applicants. Our guide to no-exam life insurance compares the options and trade-offs.
