How does term life insurance work? You pay a fixed premium for a set number of years, and if you die during that term your beneficiaries receive a tax-free death benefit. It costs far less than permanent coverage, which is why it is the right fit for most families, but the term lengths, conversion deadlines and what happens at the end are where people get caught out. This guide covers who needs it, what it costs and how to choose.
Term life insurance is the simplest kind of life insurance there is: you insure your life for a set number of years, and if you die in that window your family receives the death benefit. There is no investment component and no cash value, which is exactly why it costs so little compared with permanent policies.
This guide explains how term works from application to expiration, the types you will see, and how to pick the amount and length. For published prices by age, see our guide to term life insurance cost; to see how it compares with lifelong coverage, read term life versus whole life.
What Is Term Life Insurance?
The short answer: Term life insurance is a policy that pays a death benefit to your beneficiaries if you die within a set period, and pays nothing if you outlive it.
The National Association of Insurance Commissioners describes term insurance as coverage "intended to provide lower-cost coverage for a specific period of time." You choose the coverage amount and the term, pay the premium, and name the people who receive the money. If you die during the term, the carrier pays them; if you are alive at the end, the policy expires or continues at a higher price.
The low price comes from that structure. A permanent policy must eventually pay, because everyone dies; a term policy pays only if death happens during the years you chose, which for most buyers in their 30s and 40s is statistically unlikely. That is also why term is the most efficient way to protect an income or a debt that has an end date.
How Does a Term Life Policy Work From Start to Finish?
The short answer: You apply and are underwritten, pay a level premium during the term, and the policy either pays a claim, expires, renews at higher rates, or is converted to permanent coverage.
Apply. You answer health and lifestyle questions, and depending on age and amount the carrier may order an exam, prescription history and records. That sets your rate class, which our underwriting guide explains.
Pay the level premium. On a level term policy, the premium and death benefit stay the same for the whole term. A 20-year policy bought at 35 costs the same at 54 as it did on day one.
The term ends. Banner Life's 2026 product specifications note that after the level period "the coverage amount will be reduced and the premiums may increase," with increases starting the year after the level period. Most people either let the policy lapse because the need is gone, convert it, or replace it.
Or a claim is paid. If you die during the term, your beneficiaries file a claim with a death certificate and generally receive the benefit free of federal income tax.
What Types of Term Life Insurance Are There?
The short answer: The main types are level term, decreasing term, renewable term, convertible term and return-of-premium term, and most modern policies combine several of these features.
| Type | How it works | Best for |
|---|---|---|
| Level term | "Lock in a fixed premium for the term of the policy, while the death benefit remains the same" | Most families; income replacement |
| Decreasing term | "The death benefit decreases over the policy term" | A single debt that shrinks, such as a mortgage |
| Renewable term | Renew at the end of the term without new medical information, at higher rates | Bridging a short gap in coverage |
| Convertible term | Convert to permanent coverage "without submitting medical or other information" | Anyone whose health could change |
| Return of premium | Refunds premiums if you outlive the term, for an added cost | Buyers who value the refund over the lower price |
Most policies sold today are level term with renewal and conversion features built in. Decreasing term is the structure behind traditional mortgage life insurance, which our guide to what mortgage protection insurance is compares with family-paid level coverage.
How Long Should Your Term Life Policy Last?
The short answer: Choose a term at least as long as your longest financial obligation, which is usually the years left on your mortgage or until your youngest child is independent.
Common terms are 10, 15, 20, 25 and 30 years, and some carriers go longer: Banner Life's 2026 lineup runs to 35- and 40-year terms, with the 40-year term available to nonsmokers aged 20 to 45. Longer terms cost more each month but protect you from having to buy again at an older age, when coverage costs far more.
A parent of a newborn with a fresh 30-year mortgage usually needs 25 to 30 years. A 50-year-old with 15 years left on the loan and grown children may need only 15. Some families ladder two policies, such as a large 20-year policy for the child-raising years and a smaller 30-year policy for the mortgage, which can cost less than one large long policy. Our guide to how much life insurance you need helps size each layer.
How Much Does Term Life Insurance Cost?
The short answer: Published 2026 figures put $500,000 of 20-year term at roughly $15 to $18 a month for healthy people in their twenties and $27 to $59 a month at age 40, depending on health class.
NerdWallet's October 2026 data, which averages the three lowest preferred-class carrier rates, puts a 40-year-old man at $321 a year for $500,000 of 20-year term. MoneyGeek's average-health figures for the same age come in at $59 a month. The gap reflects different applicant profiles, which our term cost guide lays out side by side.
Against whole life the difference is large: NerdWallet's figures put the same 40-year-old man at $3,180 a year for $500,000 of whole life, roughly ten times the term premium. Our guide to whole life insurance cost explains what that extra money buys.
What Does Converting a Term Policy Mean?
The short answer: Conversion lets you switch some or all of a term policy to permanent coverage without new medical underwriting, but only before the carrier's deadline.
Conversion protects your insurability. If you develop a serious condition during the term, you can still turn the policy into permanent coverage at your then-current age without proving your health. The deadlines vary widely. Banner Life's OPTerm allows conversion for the guaranteed level period or until age 70, whichever comes first, while Guardian's standard term allows conversion in the first five years unless you add its Extended Conversion Rider.
The conversion window can close long before the term ends. Note the date in your policy and review your health and needs a year before it, because after the deadline the only way to get permanent coverage is a new application.
Who Needs Term Life Insurance?
The short answer: Term fits anyone whose death would leave someone else with a bill or a lost income for a defined number of years.
Strong fits: parents of young children, homeowners with a mortgage, couples who rely on two incomes, business owners with loans or partners, and anyone co-signing debt. Our guide to life insurance for new parents covers the most common case.
Weaker fits: people with no dependents and no debt, and needs that last a lifetime, such as funeral costs or an estate plan, which suit permanent coverage. Our guide to what type of life insurance you need sorts those cases.
The Bottom Line
Term life insurance pays your family if you die during a set period, usually 10 to 30 years, at a level premium that costs a fraction of permanent coverage. Match the term to your longest obligation, size it to the income and debts it must replace, and note the conversion deadline so you keep the option of permanent coverage.
