Start with your debts and dependents, not a rule of thumb
The amount of term life insurance you need depends on what your family would have to pay if you died today — not on a multiple of your salary or a number an agent suggests. The real calculation starts with three things: what you owe, who depends on your income, and how long they would need that income to replace.
A common shortcut is "10 times your salary," but that works only if you have no mortgage, no kids, and a spouse with a stable income. If you carry a mortgage and have young children, you likely need more. If you own your home outright and have no dependents, you might need less. The point is to build the number from your actual situation, not from a formula.
Key Takeaways
- Add up your mortgage balance, car loans, credit card debt, and any other outstanding balances to find your baseline coverage need.
- Calculate how many years until your youngest child finishes school or college, then multiply your annual household expenses by that number to cover income replacement.
- Include final expenses (funeral, medical bills, probate) as a separate line item, typically $10,000 to $15,000.
- Subtract any savings, investments, or life insurance your employer already provides, then buy a term policy for the remaining gap.
- A 20-year or 30-year term usually makes sense for families with young children; a 10-year term works if your kids are already teenagers.
The four categories that make up your number
Debts you would leave behind are the easiest to calculate. Write down your mortgage balance, car loans, student loans, credit card balances, and any other money you owe. Your life insurance should cover all of it so your family does not inherit the debt. If you have a $300,000 mortgage and $25,000 in car and credit card debt, that is $325,000 of your coverage right there.
Income replacement for dependents is the bigger piece for most families. If you earn $60,000 a year and have two children who will need support for the next 15 years, your family would need roughly $900,000 to replace that income (15 years × $60,000). In reality, they might need less because expenses drop as kids age and leave home, but this gives you a working number. If your spouse also works, you can reduce this by their income, but do not assume they will keep working at the same level while raising children alone.
Final expenses include funeral costs, medical bills not covered by insurance, probate fees, and estate taxes in some states. These typically run $10,000 to $15,000. Some people add a small buffer for immediate living expenses while the estate settles.
Existing coverage reduces what you need to buy. Check whether your employer offers group term life insurance — many provide one or two times your salary at no cost to you. Add any life insurance policies you already own. Subtract this total from your calculated need. If you need $500,000 in coverage and your employer provides $50,000, you would buy a $450,000 policy.

Why term length matters as much as the amount
A 20-year or 30-year term is standard for families with young children because it covers the years when dependents are most vulnerable and your income is most critical. A 30-year term costs more per month but protects you until your kids are adults and your mortgage is partly paid down. A 20-year term is cheaper and works if you expect your financial situation to improve — you could buy another policy later if needed.
A 10-year term makes sense only if your children are already teenagers, your mortgage is nearly paid, or you are buying supplemental coverage on top of employer insurance. The shorter the term, the lower the monthly cost, but you are also betting that you will not need coverage after it expires. Most people underestimate how long they will need protection.
Do not confuse term length with the amount. You can buy a $500,000 policy with a 20-year term or a 30-year term — the term just determines how long the coverage lasts. Pick the term based on when your dependents will no longer need your income, not based on what sounds affordable this month.
Common situations and what they usually need
Young family, one income earner, mortgage and kids: Start with your mortgage balance plus 10 to 12 years of your gross income. If you earn $70,000 and owe $250,000 on the house, you are looking at roughly $950,000. A 30-year term locks in a low rate while your kids are young.
Two incomes, young children: Each spouse should carry enough to cover their share of the mortgage and their income replacement. If both earn $60,000 and the mortgage is $300,000, each might carry $400,000 to $500,000. This way, if one dies, the survivor is not forced to sell the house or move the kids to a cheaper school.
Older children, paid-off house: Your need drops significantly. You might carry only $100,000 to $200,000 to cover final expenses and a few years of income while your teenagers finish school. A 10-year or 15-year term is often enough.
No dependents, no debt: You might need only $20,000 to $30,000 to cover funeral costs and any small debts. Some people in this situation skip term insurance entirely and rely on savings.
What happens if you buy too little or too much
Buying too little is the more common mistake. Your family ends up selling the house, pulling kids out of school, or going into debt themselves. The cost of underinsuring is real and immediate. Buying too much costs you extra in premiums every month, but the money is not wasted — term insurance is cheap, and the overage is usually small. If you are uncertain, it is safer to round up.
You can also buy a smaller policy now and add more later if your situation changes — a second child, a bigger mortgage, or a job loss that makes your income more critical. Some people buy a 30-year term for their base need and a separate 10-year or 15-year term for temporary expenses like a mortgage or college tuition. This layering approach lets you shed coverage as your obligations shrink.
Frequently Asked Questions
Should I use my take-home pay or gross income for the calculation?
Use your gross income. Your family would need to replace the full amount you earn before taxes, because they would have to pay taxes on any income they earn to replace yours. If you earn $60,000 gross, calculate as if they need $60,000 per year, not your take-home of $45,000.
Do I need to account for inflation?
Term life insurance pays a fixed amount, so inflation does erode its value over time. A simple adjustment is to add 20 to 30 percent to your calculated need to account for inflation over the term. If you calculate $500,000, buying $600,000 or $650,000 gives you a cushion. Some people prefer to buy a larger amount upfront rather than guess at inflation.
What if my spouse does not work outside the home?
A stay-at-home parent still has economic value — childcare, cooking, cleaning, and managing the household. If your spouse died, you would have to pay for childcare and household help while working. Add $30,000 to $50,000 per year to your income replacement calculation to cover those costs, then multiply by the years until your youngest child is in school full-time.
Can I use an online calculator instead of doing this by hand?
Online calculators can speed up the math, but they are only as good as the numbers you enter. Use one as a sanity check after you have built your own number from your actual debts and expenses. Many insurers offer calculators on their websites, but remember that they are selling insurance — they may skew high to justify a larger policy.
Should I buy more coverage if I have a risky job?
Your term life insurance pays the same whether you die in an accident or from illness, so your job risk does not change the amount you need. However, if your job is dangerous, make sure the policy does not exclude death from work-related accidents — read the fine print before you buy.
