10, 20, or 30 years: how to choose a term length

Term policies are generally offered in fixed lengths rather than any number of years you like. The Insurance Information Institute describes a term policy as one "purchased to last for a specified period, such as 1, 5, 10, or sometimes as much as 30 years," which is why term coverage is often summarized as running roughly 1 to 30 years. The National Association of Insurance Commissioners similarly frames term insurance as lower-cost coverage "for a specific period, like a ten year or 20-year period."

In practice, a handful of lengths tend to be the most common choices: 10, 15, 20, and 30 years. Most of these are sold as "level term," which the Insurance Information Institute notes "offers a death benefit that stays the same throughout the policy," so your coverage amount doesn't shrink as the years pass. You're usually choosing from a short menu of set lengths, not dialing in an exact custom number.

The most widely suggested approach is to line the term up with how long the people who rely on you would actually need the money. The Insurance Information Institute puts it plainly: term life "enables you to match the length of the term policy to the length of the need." For example, buying a 20-year term policy so there are funds to help pay for young children's college years down the road.

The National Association of Insurance Commissioners frames the same idea as a single question worth asking yourself: "in how many years do you anticipate the need for death benefits?" From there, you can think in terms of the obligations that have an end date. A mortgage has a payoff timeline. Children typically become financially independent after a certain number of years. Your working years, the income others count on, also have a rough horizon. Choosing a term that reaches the far edge of those needs is a common way to land on a length.

A longer term locks in level coverage for more of your life, and that protection generally carries a higher premium than a shorter term for the same benefit amount. Part of the reason is built into how insurers think about risk: the National Association of Insurance Commissioners notes that "the risk of death increases each year," so guaranteeing a fixed premium across more years means covering more of those higher-risk years.

There's a flip side worth knowing. The Insurance Information Institute notes that if you outlive a term, renewing "may be an option, but the premiums may be higher," in part because you're older when the new coverage starts. That's why simply buying a short term and renewing later isn't automatically cheaper. The practical question is rarely "what's the lowest premium today" but "which length covers my real obligations at a cost I can keep paying for the whole term."

Whatever length you choose is a snapshot of today. The National Association of Insurance Commissioners recommends that, once you have a policy, you "review it with your agent every few years to keep up with changes in your family status, income and needs." A new mortgage, a new child, a raise, or paying off a big loan can all change how long you actually need coverage.

Some policies also build in flexibility. The Insurance Information Institute points to "convertible" term policies, which can let you convert to permanent insurance "without a medical examination in exchange for higher premiums," which can be useful if your needs may outlast the original term.
