Why Buy Life Insurance? 10 Reasons It Matters More Than You Think

Most people know life insurance is important, but it’s easy to put off. It can feel like an expense for something you hope never happens. Yet for anyone whose family, partner, or business depends on them, life insurance is one of the most affordable ways to protect everything you’re working toward.

Many households are less prepared than they realize. Only 29% of adults believe they would remain financially secure for more than two years if a primary wage earner died, according to LIMRA and Life Happens’ 2026 Insurance Barometer Study. Here are 10 reasons to buy life insurance, and how to know if you need it.

1. Replace your income

If your family relies on your paycheck, life insurance can replace that income for the years they’d need it. That helps cover everyday costs like groceries, utilities, and childcare while your loved ones adjust.

2. Pay off the mortgage

A mortgage is often a family’s biggest monthly expense. A death benefit can pay off the home or cover payments for years, so your family doesn’t have to move at the hardest possible time.

3. Cover other debts

Car loans, credit cards, and private student loans can strain a surviving partner. Life insurance can clear those debts. Some debts, like cosigned loans, could otherwise fall to someone else.

4. Fund your children’s future

Life insurance can make sure college or trade school is still possible, and help with milestones like a first car or a wedding.

5. Protect the value of a stay-at-home parent

A parent who stays home provides childcare, transportation, cooking, and household management. Replacing those services can be expensive. Coverage on a stay-at-home parent is often overlooked but just as important. See life insurance for spouses.

6. Cover final expenses

The median cost of a funeral with viewing and burial was about $8,300 in 2023, according to the National Funeral Directors Association. Life insurance keeps those costs from falling on your family. See our final expense guide.

7. Fill the gap left by workplace coverage

Employer life insurance is helpful, but it’s often limited to one or two times salary and usually ends if you leave your job. LIMRA and Life Happens report that 27% of insured Americans rely only on workplace coverage. An individual policy stays with you wherever you work. See why employer life insurance isn’t enough.

8. Lock in low rates while you’re young and healthy

Life insurance gets more expensive with every birthday, and a new health condition can raise your price or limit your options. In our calculator model, a healthy 30-year-old man might pay about $20 to $30 a month for $500,000 of 20-year term coverage, and that price stays the same for the whole term. Waiting even a few years usually costs more. See affordable term life insurance rates.

9. Protect your business

If you own a business, life insurance can fund a buy-sell agreement, protect against the loss of a key person, or repay business loans so your partners and family aren’t left with a crisis. See is life insurance a business expense?

10. Leave a legacy and plan your estate

Life insurance can leave money to children, grandchildren, or a favorite charity, equalize inheritances, and give heirs cash to settle an estate. The death benefit is generally free of federal income tax for beneficiaries, according to the IRS. See life insurance for estate planning.

Do you need life insurance?

You likely need life insurance if any of these are true:

• Someone depends on your income
• You have a mortgage or debts that others would have to pay
• You have children or plan to
• You’re a stay-at-home parent
• You own a business
• You want to cover final expenses or leave an inheritance

If no one depends on you financially and you have enough savings to cover final expenses and debts, you may need little or no coverage.

How much life insurance do you need?

A quick rule of thumb is 10 to 15 times your income. A more accurate approach adds up income replacement, debts, education costs, and final expenses, then subtracts savings and existing coverage. The life insurance needs calculator does the math in a couple of minutes.

Common reasons people put off buying life insurance

• “It’s too expensive.” Term life is often far cheaper than people expect. Many healthy adults can get substantial coverage for less than a typical streaming bundle or a few takeout meals a month.
• “I’m young and healthy.” That’s the best time to buy, because your rate is locked in at today’s health and age.
• “I have coverage through work.” It’s a good start, but it’s often too small and tied to your job.
• “It’s complicated.” Buying term coverage can take a single conversation and a short application. Many healthy applicants qualify without a medical exam.
• “I don’t want to think about it.” That’s understandable. But a few minutes of planning can spare your family years of financial strain.

Which type of life insurance should you buy?

Term life insurance covers you for a set period, such as 10, 20, or 30 years, at the lowest cost. It’s the right choice for most families protecting income, a mortgage, and children. See term life insurance.

Permanent life insurance, such as whole life or guaranteed universal life, lasts your entire life. It costs more but can fit lifelong needs like estate planning, a dependent with special needs, or a guaranteed inheritance. See features of permanent life insurance.

Real-life examples

These examples are hypothetical. Sarah, 32, has a toddler and a new mortgage. She buys a 30-year term policy so her son and her partner would be protected until the house is paid off and her son is grown.

Marcus, 45, owns a small landscaping business with a partner. They each buy policies to fund a buy-sell agreement, so the surviving partner can buy out the other’s family.

Helen, 67, is retired and debt-free. She buys a small final expense policy so her children won’t pay for her funeral, and names her grandchildren as contingent beneficiaries.

How to get started

1. Estimate your need with the life insurance needs calculator.

2. Choose term or permanent based on how long you’ll need coverage.

3. Compare quotes from several insurers, since prices vary for the same person.

4. Apply and answer accurately. Many healthy applicants are approved in days.

What life insurance gives your family beyond money

The financial benefits of life insurance are easy to measure. The emotional ones matter just as much. A death benefit gives a grieving family time: time to grieve without worrying about the mortgage, time to decide whether to sell the house or stay, time for a surviving parent to adjust work schedules, and time for children to keep their routines. It can also prevent difficult decisions made under pressure, like selling a family business quickly or taking on new debt.

When to review your coverage

Life insurance isn’t a one-time decision. Review your coverage when you get married, have or adopt a child, buy a home, change jobs, start a business, or get divorced. Each of these changes can raise or lower how much protection your family needs. Many people add a second policy as their responsibilities grow rather than replacing the coverage they already have.

The bottom line

The best reason to buy life insurance is simple: it protects the people who depend on you. It replaces income, pays off debt, keeps plans like college on track, and covers final costs, often for a modest monthly premium. If someone would struggle financially without you, now is a good time to get covered.
