What is life insurance? A plain-English guide.

Reviewed by Aleen Alnono, licensed insurance agent (NPN 58310472)Updated October 202612 min read

Life insurance is easier than the jargon makes it sound. It is one promise, backed by a contract.

Life insurance is a contract in which you pay premiums and an insurance company pays a death benefit to the people you name if you die while the policy is in effect. The NAIC, the group of state insurance regulators, says that money can protect against loss of your income, funeral costs, debts, and child care costs after your death. Term covers a set number of years. Permanent coverage can last your whole life and builds cash value.

The short version: you pay a premium, the insurer promises a lump sum to your beneficiary, and the policy type decides how long the promise lasts. Term is the least expensive way to protect a family through its high-need years. Permanent costs more and lasts for life. Not everyone needs a policy. If no one relies on your income and you can cover your final expenses, you may not.

Not sure which type fits your family? A free, no-pressure conversation with a licensed professional who talks it through with you. The decision stays yours.

What life insurance is, and what it is for

The NAIC’s Life Insurance Buyer’s Guide defines it plainly: life insurance pays a death benefit (the lump sum paid to your beneficiary) if you die while the policy is in effect, in exchange for premiums you pay before your death. The Insurance Information Institute lists the common jobs the money does in its life insurance basics:

The Texas Department of Insurance sums up who it is for: not everyone needs it, and in general it is a good idea if you have family or others who rely on you financially.

How life insurance works, from application to payout

There are four people or things in every policy: the owner (who holds the contract), the insured (whose life is covered, often the same person), the beneficiary (who receives the death benefit), and the premium (what you pay to keep it in force). Here is the sequence.

  1. 1.Apply. The NAIC says you can apply through agents, by mail, and online. Depending on the policy, the insurer may ask health questions, require a doctor visit, or have a medical professional assess you. Tell the truth: the insurer will check, and false statements found later could lead it to reduce or cancel coverage.
  2. 2.Review and pay. Once approved, you pay the premium on schedule. The NAIC says you can return a new policy for a full refund within a review period, usually 10 days after you receive it.
  3. 3.Keep it in force. The Texas Department of Insurance notes most policies allow a 31-day grace period after a missed payment. After that the policy lapses.
  4. 4.The claim. Your beneficiary files with proof of death. The Texas guide says companies usually pay a single lump sum and must pay within two months after getting proof of death and verifying the beneficiary.
  5. 5.The first two years. Policies carry a two-year contestable period. If you die within it, the company may review your application and can deny payment for wrong or missing information, even by mistake, and must then return the premiums (TDI).
Easy to miss: the beneficiary line is the one people forget. The NAIC advises against naming a minor child, because insurers will not pay a minor, and notes that as the owner you can change beneficiaries at no cost. Review it after every major life event. Our guide to life insurance beneficiaries walks through it.

A policy, start to finish

Worked example · hypothetical, to show the sequence

Say Maria is 38, married, with two young children and a mortgage. She buys a 20-year term policy and names her husband Dan as the beneficiary.

Years 1 to 20: Maria pays the premium. Nothing else happens, which is how it should go. The policy has no cash value and pays only if she dies in the term (III, TDI).

If Maria dies in year 12: Dan files a claim with proof of death. The contestable period is long over. The company verifies Dan as beneficiary and pays a lump sum, within two months in Texas. Under section 101(a) of the Internal Revenue Code, the proceeds are generally not income to Dan.

If Maria is alive in year 21: the policy ends. She can renew, at a higher premium based on her age then, convert it if her contract allows it, buy something new, or let it go. Our guide to converting term to whole life covers that decision.

Term vs. permanent: the two families

The Texas Department of Insurance and the Insurance Information Institute both draw the line in the same place. Term covers a set period, from one year to 30 or more, and most term policies have no cash value. Permanent covers your lifetime if you keep paying and builds a cash value you can borrow against or withdraw. The sub-types below are the ones you will see most.

TypeHow long it lastsCash valuePremium
Term lifeA set term: one year, or 5 to 30 years or longerUsually noneLowest; stays level for the term, then rises if you renew
Whole lifeYour whole life if you keep payingYes, tax-deferredHigher than term; usually level
Universal lifeUntil the maturity date (often 95 or 100) while cash value remainsYes, tax-deferredFlexible; changes can affect how long coverage lasts
Variable lifeDepends on investment performance of the sub-accountsYes; can rise or fallDepends on the policy; the NAIC notes the greatest potential and the greatest risk

For depth, see our guides to term life, whole life, and permanent life insurance. If you are weighing whether the premium for a permanent policy is worth it, our is whole life worth it page lays out the tradeoffs.

What decides the cost

The Texas Department of Insurance says the cost depends on your age, health, and risk factors, is usually lower for younger people, and can be higher if you have health conditions, smoke, or have risky hobbies. The amount of coverage and the policy features you choose also change the premium. Group coverage through an employer is usually cheaper, because risk is based on the whole group, but it typically ends when you leave the job.

For how much age alone changes the number, see our chart of life insurance rates by age. The single most useful habit when you shop is the one the Texas guide recommends: get quotes from several companies and compare the same coverage, because rates vary by company and a cheaper policy can carry fewer features or a smaller death benefit.

How much life insurance you need

The NAIC says the amount should follow the financial needs that continue after you die, and offers questions to ask yourself.

Questions from the NAIC buyer's guide

  • Does anyone depend on me financially?
  • How much of the family income do I provide?
  • How will my family pay final expenses and repay debts after my death?
  • Do I want to leave money to charity or family?
  • If I have life insurance through my employer, is it enough?

Worked example · hypothetical numbers, to show the method

Say Jo earns $70,000 and the household needs 10 years of that income replaced, a $250,000 mortgage cleared, and funeral and estate costs covered.

Needs: $700,000 (income) + $250,000 (mortgage) + $15,000 (final expenses, the Insurance Information Institute’s suggested minimum) = $965,000.

Resources: $100,000 in savings plus basic employer group coverage. The Texas guide says a basic group benefit is often one or two times annual salary, so say $140,000.

Gap: $965,000 minus $240,000 = $725,000 to cover with an individual policy. Social Security survivors’ benefits, the Institute notes, can also reduce the need and depend on your situation.

The Institute also cautions that simple multiples of salary ignore other income and inflation, and notes you should plan to replace “hidden income” such as an employer’s share of health insurance and retirement contributions. For the step-by-step version, see how much life insurance you need.

How to buy, and what to check

Before you sign

  • The agent and the company are licensed in your state. Your state insurance department can confirm.
  • You are comparing the same coverage, amount, and term across quotes.
  • You know whether the premium is level and for how long.
  • You know the policy type: term, whole, or universal, and what it does after the first term.
  • You have named a beneficiary, and not a minor child.
  • You know your free-look period, when you can return the policy for a full refund.
  • If you are replacing a policy, you have kept the old one until the new one is in force.

The NAIC advises against canceling a current policy until the new one is in force, and the Texas guide lists what replacement can cost you: a new two-year contestable period, new health questions, and possible surrender fees on permanent policies. Our free policy review is the way to find out whether what you hold already fits.

Who may not need a policy, and when to keep what you have

If no one depends on your income and you can pay your own final expenses, you may not need life insurance. The Insurance Information Institute says exactly that in its guide to how much you need. That is a straight answer, and you do not need us for it.

If you already own a policy that names the right beneficiary and still matches your life, keeping it is usually the right call. Replacing one resets the clock on the contestable period and means new health questions. The conversations worth having are narrower: your family has grown, a term is ending, a beneficiary is out of date, or you want to know whether what you have is enough. That call is free, ends where you want it to, and is a successful review even if the answer is “keep what you have.”

Questions people ask about life insurance

01What is life insurance, in simple terms?

Life insurance is a contract with an insurance company. You pay premiums, and if you die while the policy is in effect, the company pays a death benefit to the people you named. The NAIC says the money can protect against hardships such as loss of your income, funeral expenses, medical or nursing care costs, debt repayment, and child care costs after your death.

02How does life insurance work?

You apply, the insurer reviews your age and health, and it sets a premium. You pay that premium to keep the policy in force. If you die while it is active, your beneficiary files a claim. The Texas Department of Insurance explains that companies usually pay as a single lump sum, and in Texas they must pay within two months after getting proof of death and verifying the beneficiary. Term lasts a set number of years; permanent coverage can last your whole life.

03What is the difference between term and permanent life insurance?

Term covers a set period, anywhere from one year to 30 or more, and pays only if you die in that period. Permanent coverage, such as whole life or universal life, lasts your lifetime if you keep paying and builds a cash value. The Texas Department of Insurance notes that permanent premiums are higher than term because of the savings feature and the longer coverage.

04How much life insurance do I need?

The NAIC says it depends on the financial needs that continue after your death, such as supporting your family, paying for children’s education, and paying off a mortgage. The Insurance Information Institute cautions against simple multiples of salary because they ignore other income and inflation, and suggests adding up what your dependents would need and subtracting other sources like Social Security survivors’ benefits. It also suggests planning for at least $15,000 for final expenses and estate costs.

05Is the life insurance payout taxed?

Under Internal Revenue Code section 101(a), life insurance proceeds paid because of the insured’s death are generally excluded from the beneficiary’s gross income, as the IRS explains in Publication 525. Interest earned on proceeds the insurer holds can be taxable, and so can installment payments to the extent they include interest. This is educational, not tax advice.

06Do I need a medical exam to get life insurance?

Not always. The NAIC says that, depending on the type of policy, the insurer may require a doctor visit, health questions, or a medical professional coming to your home or office. It also says a policy that does not require detailed health information usually costs more and provides less coverage. Group coverage through an employer typically does not require health questions, per the Texas Department of Insurance.

07What happens if I stop paying premiums?

Most policies have a grace period. The Texas Department of Insurance says that is commonly 31 days after the due date, during which coverage continues. If you do not pay within it, the policy lapses and your beneficiaries will not receive the death benefit. Many lapsed policies can be reinstated within a period, often five years, by paying the overdue premium with interest. You may have to answer health questions to do so.
