Start with your debts and dependents, not a rule of thumb

The amount of life insurance you need depends on what your family would have to pay if you died — not on a multiple of your salary or a number you read online. The right coverage pays off your mortgage, covers your kids' education if they're young, replaces your income for a few years, and leaves a small cushion. A single person with no dependents might need only enough to cover funeral costs and medical bills. A parent with a mortgage and two kids in school might need $500,000 or $1 million. The only way to know is to write down what your family actually owes and what they'd actually need.

Most people underestimate what they need because they forget about the years between now and when their kids finish school, or they don't account for how much it costs to replace a parent's work — childcare, cooking, cleaning, driving to activities. Start by listing every debt: mortgage balance, car loans, credit cards, student loans. Then add the cost of raising your kids to age 18 or 22, depending on your plan. Then add a few years of your household income so your spouse isn't forced to work full-time immediately while grieving and managing the house. That total is your starting point.

Key Takeaways

  • Calculate your coverage need by adding your debts, your kids' education costs, and three to five years of your household income — not by multiplying your salary by an arbitrary number.
  • Term life insurance is the cheapest way to get the coverage amount you actually calculated, because you pay only for the years you need protection.
  • A 20-year or 30-year term should cover you until your kids are grown and your mortgage is smaller, which is when you need less coverage.
  • Your employer's life insurance is usually not enough on its own, and it disappears if you change jobs.

The math: debts, dependents, and income replacement

Start with what your family owes right now. Pull your mortgage statement, car loan documents, and credit card balances. Add any student loans in your name. This is the floor — your life insurance must cover at least this much so your family doesn't inherit your debt.

Next, think about your kids. If you have young children, add the cost of raising each one from now until age 18. This includes food, housing (already counted in the mortgage), clothing, activities, and healthcare. If you plan to help with college, add that too — either the full cost or whatever you've saved so far. If your kids are teenagers, this number is smaller. If you have no kids, skip this step.

Finally, add income replacement. If you earn $60,000 a year and your spouse earns $40,000, your household loses $60,000 if you die. Your family will need time to adjust — your spouse may need to hire childcare, reduce work hours, or grieve before returning to full-time work. Most financial advisors suggest three to five years of your income. If you're the sole earner, this number is larger. If both of you work and earn similar amounts, it's smaller.

Add these three numbers together. That is the coverage amount you should look for. If the total is $750,000, buy $750,000 in coverage. If it's $1.2 million, buy $1.2 million. Do not round down to a number that feels "reasonable" — this is what your family actually needs.

Term life insurance is almost always the right choice

Term life insurance covers you for a set number of years — typically 10, 20, or 30 years — and pays out only if you die during that term. It is cheap because the insurance company knows most people won't die in that window. A healthy 35-year-old can buy $1 million in 30-year term coverage for $30 to $50 per month. The same person buying permanent coverage (whole life or universal life) would pay $300 to $500 per month for the same amount.

You want term coverage that lasts until you no longer need it. If you have a 10-year-old and a mortgage with 25 years left, a 30-year term makes sense — it covers you until your kids are grown and your mortgage is paid down. If you're 50 with teenagers and a small mortgage, a 20-year term might be enough. The point is to match the term length to when your dependents will be independent and your debts will be smaller.

Permanent life insurance (whole life, universal life, variable universal life) is more expensive and is designed to cover you for your entire life. It also builds cash value that you can borrow against. Most people do not need this. You need protection while your kids are young and your debts are large. Once they're grown and the mortgage is paid, you need less or none. Term insurance is simpler, cheaper, and fits that reality.

Your employer's coverage is a start, not a solution

Many employers offer life insurance as a benefit — often one or two times your salary at no cost to you. This is better than nothing, but it is almost never enough. If you earn $70,000 and your employer covers two times your salary, you have $140,000 in coverage. If your mortgage is $300,000 and you have two kids, that $140,000 disappears fast.

Employer coverage also ends when you leave the job. If you're laid off, fired, or quit, the coverage stops. You can usually convert it to an individual policy, but the rates will be higher because you're older. The smartest approach is to treat employer coverage as a bonus and buy individual term insurance for the rest of what you need. If your employer covers $140,000 and you calculated that you need $750,000, buy a $610,000 individual term policy. This way, you own the coverage and it stays with you if you change jobs.

Lock in your rate while you're young and healthy

Life insurance rates depend on your age, health, and smoking status. The younger and healthier you are, the cheaper the coverage. A 30-year-old non-smoker pays less than a 40-year-old non-smoker for the same coverage. If you develop high blood pressure, diabetes, or cancer, your rates go up or you may not be able to buy coverage at all.

This means you should buy coverage now, even if you think you might not need it in five years. The cost of waiting is real. If you're 35 and healthy and you wait until you're 45 to buy a 20-year term, you'll pay more per month for fewer years of coverage. If you develop a health condition in those ten years, you might not be able to buy coverage at all. Buy what you need today at today's rates, and you're protected either way.

When you apply, the insurance company will ask about your health history and may order a medical exam. Be honest. Lying on an application gives the company grounds to deny a claim later, which defeats the purpose of having insurance.

Review your coverage every few years

Your life changes. Your kids grow up. Your mortgage shrinks. Your income rises. Every three to five years, do the math again. If your kids are now teenagers instead of toddlers, you might need less coverage. If you paid down half your mortgage, you need less. If you had another child, you might need more. If your coverage amount no longer matches your actual situation, you can buy more term insurance (at your current age and health) or let your existing policy run its course.

Do not assume your coverage is still right just because you bought it five years ago. Life changes faster than most people update their insurance. A quick review takes an hour and can save your family from being underprotected.

Frequently Asked Questions

Should I buy life insurance if I have no dependents?

You need enough to cover your funeral costs (typically $7,000 to $12,000), any medical bills, and any debts in your name. A single person with no kids might buy $50,000 to $100,000 in term coverage. If you have no debt and your parents can cover funeral costs, you might not need any. The question is: who would pay if you died tomorrow?

Is it better to buy one big policy or multiple smaller ones?

One policy is simpler and usually cheaper. You pay one premium, one company manages the coverage, and your family files one claim. Multiple policies add complexity with no real benefit unless you're buying coverage from different employers or at different times in your life.

What happens to my life insurance if I get sick?

If you already own the policy, nothing happens — it stays in force as long as you pay the premiums. If you get sick after you buy it, the insurance company cannot cancel it or raise your rate. This is why buying coverage while you're healthy matters: once you own it, your health changes do not affect it.

Can I buy life insurance for my spouse?

Yes, but you need their permission and you must have a financial reason — you cannot just buy a policy on someone else and collect if they die. If your spouse's income is important to your family, or if they manage the household and childcare, you can buy coverage on them just as you would on yourself. Use the same calculation: their debts, their income replacement, and any dependents who rely on them.

Do I need life insurance if I'm retired?

Probably not, unless you have young dependents or significant debt. If your kids are grown and your mortgage is paid, your family does not depend on your income. You might keep a small policy ($50,000 to $100,000) to cover funeral costs and any final medical bills, but large coverage is unnecessary. Review your situation with the debts and dependents you actually have now.
