How life insurance works
A life policy has three roles: the owner, who controls the policy and pays the premiums; the insured, whose death triggers the payout; and the beneficiaries, who receive it. Usually you are both owner and insured, but they can be different people, and that choice matters for estate tax.
The death benefit goes to the beneficiaries named on the policy, not to the people named in your will, so a current beneficiary designation controls where the money lands. If your estate is the beneficiary, or everyone named has died, the money can end up in Probate.
Premiums depend on your age, health, the amount of coverage and how long it lasts, and the insurer usually underwrites you when you apply. Optional riders add features for an extra charge, such as a waiver of premium if you become disabled, an accelerated death benefit if you become terminally or chronically ill, or long-term care coverage.
Term vs. permanent life insurance
Term insurance covers a fixed period, such as 10, 20 or 30 years, and pays only if the insured dies during it. It has no savings component, which keeps its premiums far below those of permanent coverage for the same death benefit at the same age. When the term ends, coverage stops or can be renewed at a much higher price.
Permanent insurance is designed to last for life and carries a cash value that grows tax-deferred inside the policy. Whole life has fixed premiums and a guaranteed cash value. Universal life lets you vary premiums within limits, with interest credited to the cash value. Variable life invests the cash value in funds you choose, so it can lose money; the SEC warns that its fees make it unsuitable as a short-term savings vehicle, and any cash-value policy can lapse if its value cannot cover the policy’s charges.
The choice usually follows the need. A need that ends, such as raising children or paying off a Mortgage, matches the shape of a term policy. A need that lasts for life, such as supporting a lifelong dependent or paying an estate’s taxes, is where permanent coverage is used.
How much life insurance do you need?
A needs analysis adds up what your death would cost the people who depend on you, then subtracts what would already be there to meet it, as the formula and example below show.
Start with the income your household would lose, after taxes and the costs that disappear with you. Then subtract the Social Security survivor benefits your family could receive; each child can generally receive 75% of the deceased parent’s benefit, subject to a family maximum. Add one-time needs such as debts, college and final expenses, and subtract savings, investments and coverage you already have.
The National Association of Insurance Commissioners mentions a rule of thumb of five to eight times your income but suggests working through your own numbers instead. A parent who stays at home needs coverage too: the need is the cost of replacing child care and household work.
Needs usually shrink as debts are paid down, children grow up and savings build. Once your net worth could support your dependents on its own, you are effectively self-insured, and at that point, often around financial independence, keeping coverage becomes a choice rather than a necessity.
How life insurance is taxed
The death benefit is generally not taxable income to your beneficiaries. If the insurer pays it in installments, the interest portion is taxable. The exclusion can be lost if the policy was sold or transferred for value; then only what the buyer paid plus later premiums comes back tax-free.
Income-tax-free is not estate-tax-free. The death benefit counts in your taxable estate if you held any incident of ownership, such as the right to change beneficiaries or borrow against the policy, and a policy you give away within three years of death is pulled back in. With the federal exclusion at $15,000,000 per person in 2026, this mainly affects large estates and residents of states with lower estate tax thresholds. Having an irrevocable trust own the policy is a common way to keep proceeds out of the estate.
Cash value grows tax-deferred. On a surrender, the amount above your cost, generally the premiums you paid, is taxable income. A policy funded too quickly becomes a modified endowment contract: withdrawals and loans are then taxed gains-first, generally with a 10% additional tax before 59½.
At work, employer-paid group term coverage up to $50,000 is tax-free; the cost of coverage above that, from an IRS table, is added to your taxable wages.
Common life insurance mistakes
Most life insurance problems come from paperwork and timing, not from the choice of insurer. A death benefit only helps if it reaches the right people and was sized for the life you have now, not the one you had when you bought it. Review coverage when your family, debts or income change, and remember that life insurance pays only at death: an illness or injury that stops your paycheck is the job of disability insurance.
- Leaving an ex-spouse or someone who has died as beneficiary, or naming a minor child directly instead of a trust or custodian.
- Relying only on group coverage that may end when you change jobs.
- Buying permanent insurance for a need that ends in 20 years, or term for a need that lasts for life.
- Letting a cash-value policy lapse with a loan outstanding, which can create a tax bill with no cash to pay it.
- Leaving a spouse who earns less, or nothing, uninsured when their work at home would cost money to replace.

Discount the income stream at a conservative real rate of return; a lower rate produces a larger need.
Income gap after survivor benefits$40,000 a year for 18 years

Mortgage payoff$280,000
College fund$100,000
Final expenses$20,000
Less savings and group coverage−$150,000
Coverage need$849,700
This family needs roughly $850,000 of coverage today. The need falls each year as the mortgage is paid down and fewer years of income remain to replace, a shape that term coverage matched to the children’s ages covers without paying for insurance after the need is gone.

Life insurance in MoneyWhatIf
To see the gap a policy would need to fill, give each adult a lifespan in MoneyWhatIf, then try a What-If in which one person dies earlier. The forecast ends that person’s income on its dates, rolls retirement accounts to the surviving spouse, keeps the larger Social Security benefit, pays pensions only as their survivor setting allows and moves later years to the survivor’s filing status. The original plan stays drawn underneath, so you can compare the survivor’s cash flow and balances with it and see what a death benefit would have to replace.
Common questions
Life insurance FAQs
Can you cash out a life insurance policy?
Only permanent policies build cash value; term insurance has nothing to cash out. You can surrender a permanent policy for its cash value, paying income tax on the amount above your cost, or borrow against it. A loan is generally not taxed while the policy stays in force, but it reduces the death benefit, and a lapse with a loan outstanding can trigger tax on the gain.
Can you have more than one life insurance policy?
Yes. Many people pair group coverage at work with an individual policy they own, or buy two term policies of different lengths, such as 20 and 30 years, so coverage steps down as the mortgage shrinks and children grow up. Insurers ask about coverage you already have when you apply and may limit the total to what your income justifies. At death, each policy pays the beneficiaries named on it.
Do I need life insurance if I have no children?
Only if someone would be hurt financially by your death. A spouse or partner who relies on your income, a co-signer on your debts, or parents you support can all create a need. If no one depends on your income and your savings would cover final expenses and debts, there may be little for a policy to do.
Is life insurance through work enough?
Often not on its own. Group coverage may be smaller than your need and usually ends when you leave the job. Employer-paid coverage above $50,000 also creates taxable income: a 45-year-old with $200,000 of coverage has $150,000 of excess, and at the IRS rate of $0.15 per $1,000 a month, $270 a year is added to wages. An individual policy you own fills the gap and stays with you between jobs.
Do I need life insurance in retirement?
Many retirees do not, because the income they would replace comes from savings and benefits rather than a paycheck. Coverage can still matter if a pension ends at death with no survivor option, if losing one Social Security check would leave a spouse short, or if an estate faces estate tax. A surviving spouse usually files as single after the year of death, the widow’s penalty, which can raise taxes on the same income.
