Life Insurance: How It Works, the Types, and How Much You Need

Life insurance pays a sum of money, the death benefit, to the people you name when you die. The National Association of Insurance Commissioners (NAIC), the body of state insurance regulators, puts the common thread simply: all policies are "designed to pay money to the 'named beneficiaries' when you die." Beyond that, policies split into two families: term, which covers a set number of years and is the cheapest protection per dollar, and cash value (whole, universal and variable life), which lasts for life and builds savings but costs much more. This guide explains both, how much cover to buy, how the money is taxed, and the protections worth knowing before you sign.


The Short Answer

  • Who needs it: anyone whose death would leave someone else short of money: a partner, children, or a relative you support. Someone with no dependants often does not.
  • Term life covers a fixed period and, in the NAIC's words, "generally offers the largest insurance protection for your premium dollar."
  • Cash value life (whole, universal, variable) lasts for life and has a savings element, so "premiums tend to be higher."
  • How much: the NAIC notes that "some insurance experts suggest that you purchase five to eight times your current income," but recommends working it out from your family's actual needs instead.
  • Taxes: death benefits paid to a beneficiary are generally not taxable income, per the IRS. They can count toward your taxable estate if you owned the policy.

How Life Insurance Works

You (the policy owner) pay premiums to an insurer. If the insured person dies while the policy is in force, the insurer pays the death benefit to the beneficiaries. Usually the owner and the insured are the same person, but the NAIC notes that policies "can be taken out by spouses or anyone who is able to prove they have an insurable interest in the person." A stranger cannot insure your life; people with an insurable interest are generally immediate family, and sometimes an employer, business partner or major creditor.

Beneficiaries can be one or more people or an organization. You can name several and set a percentage for each. If a beneficiary is a minor, the NAIC suggests considering a trust. Review the designations whenever your family changes.

Summary based on NAIC consumer guidance on term and cash value life insurance.

Term details to check. Many term policies can be renewed at the end of the term "even if your health status has changed," but premiums on renewal may be higher, and the right to renew may end at a certain age. Many can also be converted to a cash value policy during a conversion period "even if you are not in good health," at a higher premium. Both features are worth having if you might need cover longer than the term.

Cash value details to check. Cash values build at different speeds: "In some policies, the values are low in the early [years] but build later." Unpaid policy loans and interest are subtracted from the death benefit, and in most policies your beneficiaries receive the death benefit, not the death benefit plus the cash value. Our guide to whether whole life insurance is worth it covers universal, variable and indexed versions and their trade-offs; its term counterpart covers what term costs by age.

"Buy term and invest the difference." The NAIC treats this as a sales slogan with a real argument behind it. Its own illustration, for a $100,000 death benefit at age 35, compares a $1,800 annual whole life premium with $250 for renewable term, a $1,550 difference. It works only if the difference is actually invested, and it has to cover higher term premiums as you age and the risk that ill health stops you buying new cover later.


Riders Worth Knowing

Riders add features for an extra premium. The NAIC describes the common ones:

  • Waiver of premium: stops premiums if you develop a covered illness or disability. Check how long you must wait after diagnosis.
  • Accidental death benefit ("double indemnity"): pays extra if death is accidental. Check how the rider defines an accident.
  • Guaranteed insurability: lets you increase cover at set future dates without a medical exam.
  • Long-term care rider: lets you use part of the death benefit for long-term care, usually once you cannot perform certain activities of daily living. See our guide to long-term care insurance for the alternatives.
  • Accelerated death benefit ("living benefit"): lets you draw part of the death benefit if you are terminally ill.

How Much Coverage You Need

The NAIC mentions the five-to-eight-times-income rule of thumb and then says "it is better to go through the above questions to figure a more accurate amount." Its questions boil down to: how much of the family income you provide, who depends on you, education you want to fund, final expenses and debts, money you want to leave, estate taxes, and inflation.

A needs calculation turns those questions into arithmetic. The following is a hypothetical illustration of that method, not a recommendation. A 35-year-old earning $70,000, with a partner and two young children:

NeedAmount
Replace income: $50,000 a year the family would need for 15 years$750,000
Pay off the mortgage$250,000
Other debts$15,000
Children's education fund$100,000
Final expenses$15,000
Total need$1,130,000
Less existing savings and investments−$80,000
Less workplace life insurance (1× salary)−$70,000
Coverage to buyabout $980,000
Illustrative figures only. The income line ignores investment returns and inflation, which roughly offset only under some assumptions. Your own figures, and whether your partner also needs cover, will differ.

That lands at 14 times salary, well above the five-to-eight rule, because this family has a mortgage and young children. A single person with no dependants might need little or nothing. That is why the NAIC prefers the question-by-question approach to a multiple.

A stay-at-home parent also needs cover. The NAIC includes "the value of the services you provide" in the calculation: childcare and household work would cost money to replace.


Is Workplace Coverage Enough?

Often not:

  • It may be modest next to a needs calculation like the one above. Check the amount in your benefits documents.
  • It is tied to the job. Ask your employer what happens to the cover, and what it would cost to keep, if you leave.
  • Coverage above $50,000 is taxable to you. IRS Publication 15-B requires employers to include in wages "the cost of group-term life insurance beyond $50,000 worth of coverage," less anything the employee paid.

The NAIC's answer to the question is "everyone's needs are different." Treat workplace cover as a base and, if you have dependants, buy an individual policy for the rest.


How Life Insurance Is Taxed

  • Death benefit: generally tax-free income. The IRS: "life insurance proceeds you receive as a beneficiary due to the death of the insured person, aren't includable in gross income and you don't have to report them."
  • Interest is taxable. If the insurer holds the money and pays interest, or pays in instalments, "any interest you receive is taxable."
  • Bought policies are different. If a policy was transferred to you for value, the tax-free amount is limited to what you paid plus later premiums and certain other amounts.
  • It can count toward the estate. The Form 706 instructions require the proceeds to be included in the gross estate if the policy pays the estate, or if the person who died held "incidents of ownership," such as the power to change the beneficiary, cancel the policy or borrow against it. For 2026 only estates above the $15 million exclusion owe federal estate tax, as our estate tax guide explains, but very large estates sometimes hold policies in a trust for this reason.

Buying It Without Getting Burned

The NAIC's own buying checklist, condensed:

  1. Decide how much, for how long, and what you can afford before speaking to anyone selling a policy.
  2. Check the agent and company are licensed with your state department of insurance.
  3. Read the application before signing, to be sure the answers are complete and accurate.
  4. Pay the company, not the agent: "make the check payable to the company, not the agent."
  5. Do not cancel an existing policy until the new one is in force. The NAIC warns that "replacing your insurance policy may be costly."
  6. Only buy a cash value policy you intend to keep. "It may be very costly if you quit during the early years of the policy."
  7. Review every few years, and when your family or income changes.

On price, the NAIC says buying online "is not necessarily cheaper": you will likely pay the same premium through an agent or online.


Finding a Lost Policy

If someone has died and you think they had life insurance but cannot find the policy, the NAIC runs a free Life Insurance Policy Locator. It "helps beneficiaries find lost life insurance policies of the deceased and connect them with unclaimed death benefits." You submit a request with the deceased person's details, and participating insurers search their records and contact you if you are a beneficiary.

FAQ

What is the difference between term and whole life insurance?
Term covers you for a set period and has no savings element, so it is much cheaper. Whole life lasts for life and builds a cash value, with much higher premiums.

How much life insurance do I need?
Enough to cover what your family would lose: years of income, debts including the mortgage, children's education and final expenses, minus savings and existing cover. The rule of thumb of five to eight times income is a rough starting point only.

Is life insurance taxable?
A death benefit paid to a beneficiary is generally not taxable income. Interest on it is, and the proceeds can count toward the owner's estate for estate tax purposes.

Do I need life insurance if I am single?
Often not, unless someone depends on you financially, you have debts co-signed by someone else, or you want to leave money to a person or charity.

Is life insurance through work enough?
Usually not for a family with dependants. The amount may be far below what a needs calculation shows, it is tied to the job, and cover above $50,000 is taxable to you.

Can I have more than one beneficiary?
Yes. Name each one and the percentage they receive, and consider a trust for minors.

How do I find out if someone who died had life insurance?
Use the NAIC's free Life Insurance Policy Locator, which asks participating insurers to search their records.
