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 owe if you died and what they would need to live on. There is no magic number that works for everyone. A single person with no dependents needs far less than a parent with a mortgage and two kids in school. The goal is to cover what your death would cost them, not to buy the biggest policy you can afford.

Most people underestimate what they actually need. They pick a round number like $500,000 because it sounds reasonable, then find out later that it would not cover their mortgage, their kids' college, and their spouse's lost income all at once. Working backward from your actual situation takes an hour and saves your family from a shortfall.

Key Takeaways

  • Add up your mortgage balance, car loans, credit card debt, and any other money your family would owe if you died today.
  • Calculate how much annual income your family would lose and multiply by the number of years until your youngest child finishes school or your spouse can retire.
  • Include college costs if you want to fund education, funeral expenses (typically $7,000 to $12,000), and a small cushion for emergencies.
  • Subtract any savings, investments, or other life insurance you already have through an employer.
  • The result is your coverage need; buy a policy that matches it, not a policy that matches your budget.

The four categories that make up your coverage need

Debts are the easiest number to find. Pull your mortgage statement, car loan paperwork, and credit card statements. Add them up. That is what your family would owe if you died tomorrow. If your spouse has income and could cover the mortgage alone, you might not need to cover the full amount — but most families cannot absorb a sudden loss of income and keep paying a large mortgage at the same time.

Lost income is the biggest piece for most working people. If you earn $60,000 a year and your spouse does not work, your family loses $60,000 a year if you die. If you have a 10-year-old child, your family might need that income for another 8 years until they finish high school and your spouse can focus on work. That is $480,000 in lost wages, before taxes. If your spouse works but earns less, calculate the difference between your income and theirs. If you both work, you each need coverage for your own income.

College and education costs vary widely. A public university costs roughly $25,000 to $30,000 per year in tuition, room, and board. A private university costs $50,000 to $60,000 per year. If you have two kids and want to fund four years each at a public school, that could be $200,000 to $240,000 total. If you do not plan to fund college, you do not need to include it — but be honest about whether your family would take on student loans instead.

Funeral and final expenses typically run $7,000 to $12,000. Cremation is less; a traditional burial with a casket and service is more. Add a small cushion for medical bills, probate costs, and immediate needs your family might have in the weeks after you die.

How to calculate your number step by step

Write down each category and fill in the blanks:

Mortgage balance$_______
Car loans and other debts$_______
Annual income you earn$_______
Years until youngest child is 18 or spouse can retire_______
Lost income total (annual income × years)$_______
College costs (if you plan to fund it)$_______
Funeral and final expenses$_______
Emergency cushion (3–6 months of household expenses)$_______
TOTAL COVERAGE NEED$_______

Now subtract what you already have. If your employer offers life insurance, write down the benefit amount. If you have savings or investments set aside, include those. Subtract that total from your coverage need. The result is how much term life insurance to buy.

Example: You earn $70,000 a year, have a $280,000 mortgage, a $15,000 car loan, two kids ages 8 and 11, and want to fund college. Your lost income for 10 years is $700,000. College for two kids at a public university is $240,000. Funeral costs are $10,000. Your emergency cushion is $30,000. Total: $1,275,000. Your employer gives you $50,000 in life insurance. You need to buy a $1,225,000 term policy.

Why buying too little costs your family more than buying too much

If your policy does not cover everything, your family has to make hard choices. They might sell the house to pay off the mortgage and rent instead. They might take out loans. Your spouse might have to work two jobs instead of being present for your kids. Your kids might not go to college, or they might graduate with large student loans.

Buying more coverage than you strictly need is cheap insurance against those outcomes. A 20-year term policy for $1,000,000 costs roughly $30 to $50 per month for a healthy 35-year-old, depending on the insurer. A policy for $1,500,000 costs only a few dollars more. The difference in your family's security is enormous.

When to recalculate your coverage need

Your coverage need changes as your life changes. When you pay off your mortgage, you need less coverage. When you have another child, you need more. When your kids finish school, you need less. When you get a raise, you might need more to replace the higher income.

Recalculate every few years or whenever something major changes: a new child, a promotion, paying off a large debt, or a significant change in your spouse's income. You do not need to buy a new policy every time — but you should know whether your current coverage still matches your situation.

The difference between coverage need and what you can afford

Your coverage need is what your family actually requires. What you can afford is what fits your budget. These are often different numbers, and that is okay — but be honest about the gap.

If you need $1,000,000 but can only afford a $500,000 policy right now, buy the $500,000 policy. It is better than nothing. As your income grows or your debts shrink, you can increase your coverage. Some people buy a smaller policy now and plan to buy a second policy later. Others buy a larger policy and accept that they are stretching their budget. The worst choice is to buy nothing because you cannot afford everything.

Frequently Asked Questions

Should I use the "10 times your income" rule?

The 10-times-income rule is a starting point, not a finish line. It works okay for someone with average debts and a spouse who does not work, but it misses people with large mortgages, multiple kids, or plans to fund college. Calculate your actual need first. If it is close to 10 times your income, the rule worked for you. If it is much higher or lower, use your real number instead.

Do I need to cover my spouse's lost income too?

Only if your spouse dies and your family would lose that income. If you are the only earner, you do not need to cover your spouse's income — but your spouse should have their own term policy to cover their income if they work. If you both work, you each need coverage for what you earn.

What if I have a lot of savings already?

Subtract your savings from your coverage need. If you have $200,000 in savings and your coverage need is $800,000, you need a $600,000 policy. Your savings act as a cushion and reduce the insurance you have to buy. But do not count money you are saving for retirement or other goals — only money your family could actually use if you died.

Can I buy more coverage than I need?

Yes. There is no penalty for buying more term life insurance than your calculated need. The extra cost is small, and it gives your family more security and flexibility. Some people buy 20 to 30 percent more than their calculated need as a buffer against inflation and unexpected expenses.

Should I include my kids' future education costs if I am not sure I will fund it?

Only include costs you actually plan to pay. If you think your kids will take out student loans or go to community college first, do not add $200,000 for a four-year university. Be realistic about what your family would actually do. You can always adjust later if your plans change.
