The right amount of life insurance depends on what your death would leave behind financially for the people who depend on you. Generic rules of thumb like “10 times your salary” give you a starting point but not precision. Here is how to calculate your actual number.
Key Takeaways
- You need life insurance if people depend on your income or unpaid labor.
- The DIME formula adds up debt, income replacement, mortgage, and education, minus savings.
- Many people are underinsured; a $1 million policy is often not enough for a young family.
- Buy young and healthy, since term life is priced mainly on age and health.
Who Needs Life Insurance
Life insurance replaces income or labor that dependents would lose if you died. You likely need it if you have a spouse or partner who relies on your income, children who need support, co-signed debt a survivor would owe, or someone who depends on your unpaid work (like childcare) that would cost money to replace. You probably do not need it if you are single with no dependents, your spouse earns enough on their own, or your children are self-sufficient adults.
The DIME Formula
A practical way to calculate your need:
- D, Debt: all debts your family would inherit, like car loans, student loans, personal loans, and credit cards. Add the full remaining balance of each.
- I, Income: how many years of income your family needs replaced, times your annual income. A family with young children often needs 10 to 15 years; one with older kids and a working spouse might need 5 to 7.
- M, Mortgage: the full remaining mortgage balance, so your family can keep the home without your income.
- E, Education: estimated college costs per child. A four-year public university runs very roughly $140,000 including room and board, and private $240,000 or more, though costs vary widely and rise over time.
Add D plus I plus M plus E, then subtract savings and assets your family could use. The result is your coverage need.

Example Calculation
A 35-year-old with a spouse and two children (ages 5 and 8), household income $95,000, and a $280,000 mortgage:
| Component | Amount |
|---|---|
| Debt (car loan plus credit cards) | $35,000 |
| Income replacement ($95,000 x 12 years) | $1,140,000 |
| Mortgage balance | $280,000 |
| Education (2 children x $140,000) | $280,000 |
| Total need | $1,735,000 |
| Minus existing savings and investments | -$85,000 |
| Recommended coverage | $1,650,000 |
A $1 million policy, which many people think of as a lot, would leave this family short by more than $600,000.
What Coverage Costs in 2026
Term life is priced mainly on age and health, so the younger and healthier you are when you buy, the lower your premium for the whole term. As an illustration for a healthy non-smoking 30-year-old, a 20-year, $1 million term policy might run roughly $35 to $55 a month, and a 30-year policy somewhat more, with women generally paying a bit less than men. These are examples only, and your actual rate depends on your health and insurer, so get quotes. Waiting five years to buy can raise the monthly cost meaningfully for the same coverage, so locking in young is usually cheaper.
The Stay-at-Home Parent Problem
Stay-at-home parents provide labor with real economic value: childcare, cooking, transportation, and household management. If one died, the working spouse would have to pay for those services, which can run $30,000 to $60,000 a year for two children in many areas. So a stay-at-home parent needs coverage based on the cost to replace that labor, not just earned income (which may be zero). A $500,000 to $750,000 policy is often appropriate for a stay-at-home parent with young children.
Where to Buy
Online term life marketplaces let you compare quotes from multiple carriers in minutes. Platforms like Policygenius and Ladder offer comparisons and same-day coverage for healthy applicants, while traditional agent-sold policies suit people with health conditions who need more complex underwriting. Compare a few options before buying, and consider talking to a fee-only advisor if your situation is complicated. See our guide on how to choose a financial advisor.
FAQ
How much life insurance do I actually need?
Use the DIME formula: add your debts, years of income to replace, mortgage, and education costs, then subtract savings. Many young families land well above $1 million.
Is term or whole life better for most people?
For most people who need coverage during their working and child-raising years, term life provides the most protection per dollar. Whole life is more expensive and suits specific situations.
Do stay-at-home parents need life insurance?
Often yes, based on the cost to replace their childcare and household labor, which can be tens of thousands of dollars a year.
Does buying young really save money?
Yes. Term life is priced on age and health, so buying while you are young and healthy locks in a lower rate for the full term.
Bottom Line
Skip the generic multiples and calculate your real need with the DIME formula, since most families need more than they assume. Cover your debts, years of income, mortgage, and your kids’ education, insure stay-at-home parents for their labor, and buy term while you are young and healthy.
