How Does Life Insurance Work? What It Is and What It Covers

Life insurance covers a specific financial risk: the income your family would lose if you died and your earnings stopped. It pays out only on death, unlike health insurance, which covers medical costs while you're alive. Some permanent policies also build savings over time, but income replacement is the core purpose.

Life insurance comes in two main types: term and permanent. Both pay death benefits if you die while covered. Premiums stay the same throughout the policy period. Most people just need term life.

Rates are based on average monthly quotes for 40-year-old nonsmokers with average weight and health across insurers, based on MoneyGeek's analysis of composite quotes for a $500,000 policy. Term life figures use a 20-year term length.

Variable life insurance is another type of permanent coverage. It lets you invest your cash value in market-based subaccounts, so your cash value and potential death benefit can grow faster than whole life insurance, or shrink if the investments perform poorly. Indexed universal life insurance works differently: it ties growth to a stock market index with a cap on gains instead of direct market investment. 

Guaranteed universal life guarantees the death benefit to a set age, often 100 or 121, with little or no cash value growth. Final expense insurance is a small, guaranteed permanent policy sold without a medical exam.

You pay premiums to keep your policy active. When you die, your beneficiaries submit a death certificate and the insurer pays the death benefit within 14 to 60 days.

Your age, health, coverage amount and policy type determine your cost. Insurers assess your risk through a process called underwriting: reviewing your medical history, running a health questionnaire and, for most policies, a brief physical exam. Younger, healthier people pay less. Your rate locks in once you're approved and stays the same as long as you pay on time.

Term life insurance covers you for a set number of years: 10, 20 or 30. You choose the term when you buy. If you die during that window, your beneficiaries get the death benefit. If you outlive the policy, coverage ends with no payout and no refund of the premiums you paid. Term costs less than permanent because it covers a finite period and has no savings component.

You can name anyone with an insurable interest in your life as your beneficiary. Insurable interest means your death would create a financial loss for them: a spouse who relies on your income, children you support or a business partner whose share of the business would be affected. Common choices include a spouse, children, a trust or a charitable organization.

Naming a trust as your beneficiary, rather than a person, controls how and when a minor child receives the money, instead of getting a lump sum at 18. You can name more than one beneficiary and set the percentage each receives, and you can change your beneficiary at any time by submitting a new form to your insurer.

Keep beneficiary designations current. 

Your designation overrides your will. An ex-spouse named before a divorce and never updated will receive the payout regardless of what the divorce decree says. Update after marriage, divorce, the birth of a child or the death of a named beneficiary. Name a contingent beneficiary as a backup. Without one, if your primary beneficiary dies before you, the death benefit goes to your estate and must clear probate (the court process for distributing an estate, which can take months) before your family can access it.

Life insurance covers death from illness, accidents and natural causes. In 2024, U.S. insurers paid $89 billion in death benefits to beneficiaries, according to the American Council of Life Insurers. Nearly every claim filed throughout the industry's history has been paid. Insurers pay the death benefit regardless of how the insured died, as long as the cause isn't listed in the policy's exclusions.

Your beneficiaries receive a tax-free lump sum they can use for:

• Immediate expenses: Funeral and burial costs ($7,000 to $15,000)
• Outstanding debts: Mortgage balance, car loans, credit cards
• Ongoing expenses: Monthly bills, groceries, childcare
• Future needs: College tuition, income replacement for five to 10-plus years

Every life insurance policy excludes specific circumstances. Common exclusions include:

• Suicide within two years: A suicide clause blocks payout if death occurs by suicide within the policy's first two years. After that period, suicide is covered like any other cause of death.
• Misrepresentation on your application: If you die from a condition you didn't disclose, the insurer can deny the claim, particularly within the first two years.
• War and terrorism: Policies exclude deaths from acts of war or terrorism.
• Criminal activity: If you die while committing a felony, the insurer may deny the claim.
• Risky activities: Some policies exclude deaths from high-risk activities like skydiving or BASE jumping unless you add extra coverage.
• Beneficiary involvement: If a life insurance beneficiary causes the policyholder's death, that beneficiary loses the right to collect the death benefit. Proceeds go to contingent beneficiaries instead.

Term life is the most affordable policy type across all age groups. A 20-year-old woman pays $30 per month for a $500,000 term policy; a 20-year-old man pays $36. Whole life costs the most: $303 per month for a 20-year-old woman and $337 for a man the same age. Age drives costs up sharply regardless of policy type.

Life insurance underwriting is the process insurers use to evaluate your risk and determine whether you qualify for coverage and how much you'll pay. The insurer reviews your age, health history, medical exam results, prescription history, tobacco use, occupation and lifestyle.

This review takes two to six weeks for policies requiring a medical exam, while some no-exam policies can approve applicants within 24 to 48 hours.

You can file a life insurance claim in three steps:

1. Get a certified copy of the death certificate. The funeral home can order multiple copies. Request at least two: one for the insurer and one for your records.
2. Notify the insurer. Call the claims department or submit an online notification. Have the policy number ready.
3. Submit the claim form. Complete and return the insurer's claim form along with the death certificate and the original policy document if available.

A few things can slow the process:

• Contestability period. Deaths that occur within the first two policy years trigger an investigation before the insurer pays.
• Missing beneficiary designation. No named beneficiary means the death benefit goes to the estate, which must clear probate before your family can access it. Probate can take months.

Many states require insurers to pay or deny a claim within 30 days of receiving a complete submission, though timelines vary. Keep policy documents and insurer contact information somewhere your beneficiaries can find them.

After a claim is approved, beneficiaries choose how to receive the death benefit. The insurer pays the death benefit itself tax-free, regardless of which option a beneficiary chooses. Any interest that accumulates on funds held by the insurer is taxable as ordinary income.

Most beneficiaries choose the lump sum because it provides the most flexibility. The annuity option removes the risk of managing a large sum all at once, which some beneficiaries prefer.

Get quotes from at least three insurers. Rates for the same $500,000 term policy vary by hundreds of dollars annually across carriers for identical applicants. Once you've compared quotes, name a specific person as your primary beneficiary and a contingent beneficiary as a backup. Store your policy documents somewhere your beneficiaries can find them.

Review your coverage after any major life change: marriage, divorce, a new child or a large change in income or debt.
