What Is Life Insurance and How Does It Actually Work?

Life insurance is one of those things most people know exists but few people truly understand. If you’ve ever wondered what it actually does, why people buy it, or how the money part works, this article is for you. We’ll walk through the whole thing from scratch, in plain English, so you can decide whether it belongs in your financial picture.

The Short Answer

Life insurance is a contract between you and an insurance company. You pay a regular amount of money, called a premium. In exchange, the insurance company promises to pay a lump sum of money, called a death benefit, to the person you choose when you die.

That’s it at the core. You pay a little each month so that someone you care about receives a significant amount of money when you’re no longer here. The purpose is to replace the financial support you would have provided, so the people who depend on you aren’t left struggling.

You probably already pay for car insurance and health insurance. Those protect you from financial disasters related to car accidents and medical bills. Life insurance works the same way, except it protects your family from the financial disaster of losing your income. The car keeps running. The hospital bills get paid. And with life insurance, the mortgage, the groceries, and your kids’ future get covered too.

The Key Terms, Explained Simply

Life insurance has its own vocabulary. Here are the terms you’ll encounter, translated into plain language.

TermWhat It Means
PremiumThe amount you pay for your policy, usually monthly or annually. Think of it as the price of the coverage.
Death BenefitThe lump sum of money paid out when you die. This is the amount your beneficiary receives. It's also called the "face amount" or "coverage amount."
BeneficiaryThe person (or people) you choose to receive the death benefit. This is usually a spouse, partner, child, family member, or trust.
PolicyholderThe person who owns the policy and pays the premiums. That's you.
CarrierThe insurance company that issues your policy and pays the death benefit. Companies like Mutual of Omaha, Protective, or Pacific Life are carriers.
UnderwritingThe process the carrier uses to evaluate your health and risk and decide how much to charge you. More on this below.
TermThe length of time a policy lasts. A "20 year term" means the policy covers you for 20 years.
RiderAn optional add-on to your policy that provides extra features, like waiving your premium if you become disabled. Riders cost a small additional amount.

You don’t need to memorize these. But having them in your back pocket makes everything else in this article (and in the life insurance world) easier to follow.

How It Works, Step by Step

Here’s the full lifecycle of a life insurance policy, from the moment you start looking to the moment it pays out.

1

You Decide You Need Coverage

Something in your life, a child, a mortgage, a partner who depends on your income, makes you realize your family would be financially vulnerable without you. That’s the starting point for most people. You decide to look into it.

2

You Choose a Coverage Amount and Term

You decide how much money your beneficiary should receive (the death benefit) and how long you need the coverage to last (the term). Most people aim for 10 to 15 times their annual income, with a term that lasts until their youngest child is independent or their mortgage is paid off.

3

You Apply

The application asks about your age, health, lifestyle, and medical history. Some policies also require a brief medical exam (a nurse visits your home, checks your vitals, and draws blood). Other policies skip the exam entirely and use health databases and your answers to make a decision. The application itself takes about 10 to 15 minutes.

4

The Carrier Underwrites Your Application

The carrier’s underwriting team reviews your application and determines your risk level. Based on that, they assign you a «rate class,» which determines your premium. Healthier applicants pay less. Applicants with more risk factors pay more. This process can take a few days (for no-exam policies) to a few weeks (for fully underwritten ones).

5

You Get Approved and Your Policy Starts

Once approved, you review the offer, accept it, and start paying your premium. Your coverage begins on the effective date listed in the policy. From that point forward, your beneficiary is protected for the coverage amount you chose.

6

You Pay Your Premium, and Life Goes On

Most people set up automatic payments and don’t think about their policy again. Your premium stays the same for the entire term. You don’t need to re-qualify, re-apply, or do anything else. The policy works quietly in the background.

7

If Something Happens, The Benefit Is Paid

If you pass away while the policy is active, your beneficiary contacts the carrier and files a claim. The carrier verifies the claim and pays out the full death benefit, usually within a few weeks. The money is typically tax-free, and your beneficiary can use it for anything: the mortgage, daily expenses, childcare, education, debts, or anything else they need.

8

If the Term Ends and You're Still Here

If you outlive your term policy, the coverage simply expires. No money is paid out. You can usually renew on a year-to-year basis at a higher rate, convert to a permanent policy (if your policy includes that option), or let it lapse. By this point, your mortgage may be paid off, your kids may be independent, and you may not need the coverage anymore. That’s actually the best outcome.

«If I might not use it, why am I paying for it?» The same reason you pay for car insurance even if you never have an accident. You’re not paying for something you’ll use. You’re paying so your family is protected if the worst happens. The value isn’t in using it. The value is in knowing it’s there.

The Two Main Types of Life Insurance

There are many variations, but almost every life insurance product falls into one of two categories. Here’s a quick overview of each.

Most Common

Term Life

Covers you for a set number of years (10, 15, 20, 25, or 30). You pay a fixed premium for the entire term. If you pass away during the term, your beneficiary gets the full death benefit. If the term ends and you’re still alive, the policy expires.

Best for: Families who need to protect their income during the years when their financial obligations are highest, like raising children or paying off a mortgage.

Cost: The most affordable option. Gives you the most coverage for the lowest premium.

Specialized

Whole Life

Covers you for your entire lifetime, as long as you pay the premiums. Part of each payment goes toward a cash value that grows over time. You can borrow against that cash value while you’re alive.

Best for: People who need permanent coverage, like leaving a guaranteed inheritance, funding a special needs trust, or covering estate taxes.

Cost: Significantly more expensive, typically 5x to 10x the cost of term for the same death benefit.

traditional coverage.

For most families, term life insurance is the right starting point. It covers your family during the years they need it most, at a price that fits a normal budget. Whole life is a more specialized tool that makes sense in specific financial planning situations.

If you’re not sure which type fits your situation, that’s normal. You can compare both types at Ozzo and see what each would cost for your specific profile. Seeing real numbers side by side often makes the decision straightforward.

What Determines Your Price

Your premium is based on how much risk you represent to the carrier. The less risky you are to insure, the less you pay. Here are the factors that matter most.

Your Age

The single biggest factor. The younger you are when you apply, the lower your premium. Rates increase roughly 8 to 10 percent for every year you wait. This is the main reason financial professionals recommend buying coverage sooner rather than later.

Your Health

Your current health and medical history are evaluated during underwriting. Conditions like high blood pressure, diabetes, or a history of heart disease can increase your rate. Well-managed conditions are viewed more favorably than uncontrolled ones.

Your Gender

Women statistically live longer than men, which means they represent less risk and pay lower premiums. The difference is typically 15 to 30 percent less for the same coverage.

Tobacco Use

Smoking or using nicotine products is one of the biggest rate multipliers. Smokers typically pay 2 to 3 times more than non-smokers for the same coverage. Most carriers require 12 months nicotine-free to qualify for non-smoker rates.

Coverage Amount and Term Length

More coverage costs more, but not proportionally. Doubling your death benefit typically increases your premium by 50 to 80 percent, not double. A longer term also costs more than a shorter one, but the difference is often smaller than people expect.

Lifestyle and Occupation

High-risk hobbies (skydiving, scuba diving), dangerous occupations (mining, logging), a poor driving record, or frequent international travel to certain regions can all affect your rate. These factors carry less weight than age and health, but they’re part of the picture.

Most people overestimate what life insurance costs by two to three times. A large part of the reason people don’t have coverage is that they assume they can’t afford it. The best way to find out what coverage actually costs for your situation is to look at a real quote. It takes about 2 minutes at Ozzo, and the number is often lower than people expect.

What Can the Money Be Used For?

When a life insurance policy pays out, the beneficiary receives a lump sum with no restrictions on how it’s spent. The money is almost always income-tax-free. Here’s how families commonly use it.

Replacing income. The most common use. The death benefit replaces the income the family depended on, covering everyday expenses like groceries, utilities, childcare, and transportation for years to come.

Paying off the mortgage. Many families use the payout to eliminate their mortgage entirely, removing the largest monthly expense and allowing the surviving family to stay in their home.

Covering debts. Student loans, car loans, credit cards, and medical bills can all be paid off so the surviving family starts with a clean slate instead of inheriting financial obligations.

Funding education. Parents who want their children to attend college can include future education costs in their coverage amount, giving their kids access to opportunities regardless of what happens.

Covering final expenses. Funeral and burial costs can range from $7,000 to $15,000 or more. The death benefit can cover these costs so the family doesn’t have to.

Creating breathing room. Grief is disorienting. Having financial stability during that time gives a family the space to process, make decisions, and adjust without the pressure of an immediate financial crisis.

Who Needs Life Insurance?

Life insurance makes the most sense for people whose death would create a financial hardship for someone else. If anyone depends on your income, your labor, or your financial support, there’s a case for coverage.

Parents

If you have children who depend on you financially, life insurance is one of the most important things you can have. It ensures they’re cared for even if you can’t be there.

Spouses and Partners

If your household relies on two incomes, losing one could mean the other person can’t cover the mortgage, bills, or everyday expenses alone. Coverage protects both of you.

Homeowners

If you have a mortgage, life insurance can ensure it gets paid off. Your family keeps the home without having to figure out how to cover the payments on less income.

People with Debt

If you have student loans, car loans, or credit card debt that would burden someone else, life insurance can cover those obligations so your family inherits support, not debt.

Business Owners

Life insurance can fund buy-sell agreements, protect business partners, cover key employees, or ensure business debts don’t fall on your family.

Caregivers

Stay-at-home parents or people caring for elderly relatives provide labor with enormous economic value. Life insurance can fund the cost of replacing that care.

If nobody depends on your income or financial support, you may not need life insurance right now. A single person with no children, no mortgage, and no co-signed debts, for example, may not have a pressing need. That can change as life circumstances change, but there’s no reason to buy something you don’t currently need.

How a Claim Gets Paid

When the policyholder dies, the beneficiary files a claim with the carrier. Here’s what that process looks like.

The beneficiary contacts the carrier. This usually means calling the carrier’s claims department or submitting a claim form online. The carrier will need a certified copy of the death certificate and the policy number.

The carrier reviews the claim. For straightforward cases, this takes a few days to a couple of weeks. The carrier verifies the death, confirms the policy is active, and checks that premiums were current. In the vast majority of cases, claims are approved without issues.

The benefit is paid. Most carriers offer a lump sum payment by check or direct deposit. Some also offer the option to receive the money in installments or to place it in an interest-bearing account. The full death benefit is paid out, and in nearly all cases, it’s completely income-tax-free to the beneficiary.

How Long It Takes

Most claims are paid within 30 to 60 days after the carrier receives all required documents. Some are paid faster. Delays can happen if the death occurs within the first two years of the policy (called the «contestability period»), if the cause of death is under investigation, or if there are disputes about the beneficiary. These situations are uncommon.

Things People Commonly Wonder About

A few questions come up over and over. Here are the honest answers.

Can the carrier refuse to pay a claim?

It’s rare, but it can happen. The most common reasons are material misrepresentation on the application (you lied about something significant, like a major health condition or tobacco use) or death during the contestability period under suspicious circumstances. If you’re honest on your application and your premiums are current, the overwhelming majority of claims are paid as expected. Life insurance carriers paid out over $90 billion in death benefits in the U.S. in recent years. Paying claims is what they do.

What happens if I stop paying my premium?

If you miss a payment, most policies have a grace period, usually 30 or 31 days, during which you can pay without losing coverage. If you don’t pay within the grace period, the policy lapses and coverage ends. Some whole life policies with accumulated cash value can use that cash value to cover missed payments temporarily, but term policies don’t have that option. If your policy lapses, you’d need to reapply, which means going through underwriting again at your current age and health.

Can I change my beneficiary?

Yes, at any time. You can update your beneficiary by contacting your carrier and filling out a simple form. It’s a good idea to review your beneficiary designation after major life events like marriage, divorce, or the birth of a child. Your beneficiary designation overrides your will, so keeping it current is important.

Can I have more than one policy?

Yes. Many people carry multiple policies. For example, you might have a group policy through your employer and a personal term policy on the side. Or you might have a large term policy for the next 20 years and a smaller whole life policy for permanent needs. There’s no rule against it, as long as the total coverage amount is reasonable relative to your income and financial obligations.

Does life insurance cover suicide?

Most policies include a suicide clause that excludes coverage if the policyholder dies by suicide within the first one to two years of the policy (the exact period depends on the carrier and state). After that period, death by suicide is typically covered the same as any other cause of death.

Getting Started Is Simpler Than You Think
