How to Choose a Term Life Insurance Length

The amount of term life insurance and the length of the term are two different decisions. Families often spend more time on the amount and then pick a term because it was the option on a quote form. The length matters just as much. When the term ends, the death benefit ends with it, unless you renew, convert, or replace the policy — and those options are not always available or affordable later.

The National Association of Insurance Commissioners (NAIC) describes term life as coverage for a set period. Choosing that period well is the subject of this guide. For how to estimate the amount, see how much term life insurance do I need. Premiums vary by age, health, amount, and term length.

Start with the longest need, not the shortest quote

Write down what the money would have to do, and for how many years:

• A mortgage or other housing cost, and the years left on the loan.
• Income a surviving spouse or partner would need, and for how long.
• Childcare and the years until the youngest child is independent or through school.
• Other debts that would still be due.

The term should usually last at least as long as the longest of those jobs. If a 30-year mortgage and a newborn are both in the picture, a 10-year term is likely too short, even if the first-year premium is lower. If the only remaining need is a 12-year loan and no dependents, a 30-year term may be more coverage-years than you want to pay for.

Common term lengths are 10, 15, 20, and 30 years, though other durations exist. You do not have to use a round number if a product offers a length that better matches the need, but you should not pick a length only because it was the default on a website.

A shorter term is not automatically a better deal

Shorter terms often have a lower premium at the start. That can be the right fit when the need is clearly short — a known number of years until a loan is paid, or until a temporary income gap closes. It is a weak fit when you are hoping you can “just get another policy later.” Later, you will be older, and your health may have changed. A new policy may cost more, offer less, or not be available at the amount you want.

If you are unsure, it is often more conservative to choose a term that outlasts the need by a few years than to cut it close. You can always review the policy later and decide not to replace it when it ends, if the need is gone. You cannot extend a term that has already expired. See what happens when term life ends.

Laddering, conversion, and more than one policy

Some households use two term policies with different end dates — a larger layer for the years of a mortgage and young children, and a smaller layer that lasts longer. That approach is called laddering. It has to be set up as two policies (or a later second policy), and it only works if you still qualify when you add the second layer. It is one way to avoid paying for a large benefit after the largest need is gone. See decreasing term versus level term if the need itself shrinks on a schedule, such as a mortgage balance.

Ask whether the policy can be converted to permanent coverage later, and until when. You may not want whole life now, and you may want the option if part of the need becomes permanent or if your health changes. The conversion window can close before the term ends. See can you convert term life to permanent.

Coordinate the term with work coverage and with a spouse’s policy

Employer group life is often a flat amount or a multiple of salary, and it may end when you leave the job. Do not size your individual term as if that group coverage were guaranteed to last as long as your mortgage. An individual policy you own can be the layer that actually lasts the full term you chose. See group versus individual life insurance.

If two people share a household, each person’s term length should match that person’s role and the years the household would need money if that person died. The terms do not have to be identical. A parent who would be providing childcare for 18 more years and a parent with a 30-year mortgage may need different lengths, or the same length if one policy is meant to cover both jobs.

St. Louis-area families sizing both amount and length can also use how much life insurance do I need in St. Louis and the life insurance needs calculator as planning tools, not as quotes.

The bottom line

Choose a term length that lasts as long as the need, not only as long as the lowest introductory premium. Build in a little room, ask about conversion, and do not count on a future application to fix a term that was too short. A licensed insurance broker can help you match a term life policy to the years ahead of you, and compare more than one length side by side.
