The right amount of term life insurance is the money your dependents would need to cover debts and replace income for the years they would rely on it, minus what they already have in savings, work coverage, and other sources. The National Association of Insurance Commissioners (NAIC) frames it the same way: how much to buy depends on the financial needs that would continue after your death, such as supporting a family, paying for children’s education, and paying off a mortgage.
That makes the number personal. A single parent with a mortgage and two young children has a very different figure from a couple with no children and no debt. This guide shows three ways to count, with hypothetical numbers so you can see the arithmetic, and then covers how to pick a term length. It is US-centric general education, not a recommendation for any particular household.
Start with who depends on your income
Life insurance exists to replace income and cover obligations that would otherwise land on someone else. If nobody relies on your paycheck or would be left with your debts, you may need little beyond final expenses. The NAIC suggests starting with a simple question: does anyone depend on you financially?
People who commonly have a real need:
- Parents of minor children
- A spouse or partner who relies on your income for rent or a mortgage
- Someone who co-signed debt, such as a private student loan or a business loan
- A caregiver for a disabled or older relative
- A stay-at-home parent whose unpaid work would have to be replaced with paid help
The last item is easy to overlook. If a stay-at-home parent died, the household might pay for child care, meals, and transportation that used to be handled at home, so coverage on that adult can be reasonable too.
Method 1: a quick income multiple
Some guides multiply gross annual income by a number such as 10 or 15. The idea is that a lump sum of that size could replace a meaningful share of income for many years. It is quick, but it ignores your debts, your savings, a spouse’s income, and the ages of your children. These multiples are rules of thumb that circulate widely rather than figures set by a regulator, so use one only as a sanity check on a fuller count. Two people with the same salary can need very different amounts: a 30-year-old with a newborn and a 55-year-old with grown children are not in the same position.
Method 2: add up the needs (the DIME approach)
DIME is a common memory aid for Debt, Income, Mortgage, Education. You total each piece and then subtract what you already have.
- Debt: credit cards, car loans, student loans, and personal loans, not counting the mortgage.
- Income: the number of years your family would need replacement income, multiplied by the annual amount.
- Mortgage: the remaining balance, if you want the home paid off.
- Education: future costs for children’s college or training, if relevant.
Here is a hypothetical example, not a typical household. Suppose someone earns $80,000, has two young children, a $260,000 mortgage balance, $15,000 in car and credit card debt, and wants to replace 10 years of income.
| Need | Hypothetical amount |
|---|---|
| Non-mortgage debt | $15,000 |
| Income replacement (10 years x $80,000) | $800,000 |
| Mortgage payoff | $260,000 |
| Education (assume $50,000 per child) | $100,000 |
| Final expenses | $15,000 |
| Total need | $1,190,000 |
Now subtract resources. If the family has $60,000 in savings earmarked for this purpose and $100,000 of group life insurance through work, the gap is $1,190,000 minus $160,000, or $1,030,000. Those inputs are assumptions you would replace with your own. Notice that this particular result lands close to the income multiples some guides quote, which is a useful cross-check when it happens, but it will not always.
Method 3: replace income to a target date
A third approach starts from time rather than dollars. Ask until what date your family would struggle without your income. Common targets are the year the youngest child finishes school, the year the mortgage is paid off, or the year a spouse could realistically retire.
Replacing a full income for nearly two decades can produce a very large number, so many people replace only the shortfall that a surviving spouse’s pay would not cover. If the household needs $80,000 a year and a spouse earns $45,000, the shortfall is $35,000 a year, or $665,000 over 19 years before any adjustment for inflation or investment growth. Professionals often work with a discount rate and an inflation assumption; the flat arithmetic here assumes the two roughly offset. If you want a more refined figure, a licensed agent or a fee-only planner can run it.
Count what you already have
Subtracting existing resources keeps you from buying more than you need. Look at:
- Employer group life insurance. Often a multiple of salary, but it usually ends when you leave the job, so treat it as a bonus rather than a foundation.
- Savings and investments your family could use without penalty.
- Survivor benefits. Social Security may pay benefits to some surviving spouses with young children and to minor children, depending on your work record. Check your own record with the Social Security Administration instead of guessing.
- A spouse’s income. Include it, but be realistic about whether it would stay the same, especially if they would need to cut hours to care for children.
- Existing individual policies.
Do not count home equity as available cash. Selling the house is exactly what a policy is meant to prevent.
Choosing a term length
NAIC describes term insurance as coverage for a set period that pays only if death occurs during that period, intended as lower-cost protection for a specific need. Terms are commonly offered in lengths such as 10, 15, 20, 25, or 30 years, though availability varies by insurer.
A practical way to choose: find your longest-running obligation, usually the mortgage or the youngest child’s path to independence, and look for a term that reaches it. A person with a newborn and a new 30-year mortgage faces a much longer exposure than someone with a teenager and a few years left on a loan. Longer terms generally cost more because the insurer covers you for more years, so the length is a tradeoff worth pricing out.
Laddering instead of one big policy
Needs often shrink as the mortgage balance falls, children grow up, and savings build. Some people split coverage into layers, for example a larger amount for a shorter term plus a smaller amount for a longer one, so total coverage steps down when the need does. Whether the extra paperwork is worth any savings depends on actual quotes, which vary, so compare them.
What changes the price
Prices for a given amount depend mainly on age, health, tobacco use, term length, and coverage amount, and they differ between insurers, so compare several quotes for the same amount and term. Waiting generally costs more because you are older, and a new health condition can make coverage costlier or harder to get. For how term compares with permanent policies, see term life vs whole life insurance.
Mistakes worth avoiding
- Buying too little because of cost. If the budget is tight, a shorter term can bring the premium down while keeping the amount adequate for the highest-need years.
- Relying only on work coverage. It can disappear with a layoff.
- Forgetting to update beneficiaries. Divorce, a new baby, or a death in the family are reasons to review who is named. Naming a minor child directly can complicate payment because a court may need to appoint someone to manage the money, so ask an attorney in your state about trusts or custodianship.
- Misstating health or tobacco use on the application. An insurer can contest a claim over a material misstatement, and policies commonly have a contestability period in their first years. Answer accurately.
- Letting coverage lapse. Term ends at the end of the term. If you outlive it and still need coverage, new policies at an older age generally cost more.
- Ignoring other risks. Life coverage does not address lawsuits; see when you need an umbrella policy. Owning a business also means business insurance is a separate question.

Where this comes from
This guide draws on the National Association of Insurance Commissioners’ consumer pages and buyer’s guide for life insurance, which describe how term and permanent insurance work and how to think about how much to buy. The worked numbers are hypothetical arithmetic, not statistics. Prices, rates, and benefit amounts change and differ by insurer and state, so check current figures with your state insurance department, the Social Security Administration, and a licensed professional.
