10, 20, or 30 years: choosing the term length

The term length decision is easier than it looks, because it has a correct starting point: how long will someone depend on the income this policy replaces? Everything else is adjustment.

Start from the last dependency

List the things the policy is for and the year each one ends. A newborn is independent around 2048. The mortgage is paid off in 2051. Your spouse reaches retirement age in 2055. The term should reach the last of those, or close to it. For most young parents that lands at 25 or 30 years; for someone buying at forty-five with teenagers and a half-paid mortgage, often 15 or 20.

Why longer is usually the safer error

A term policy can be cancelled at any time with no penalty, so buying too long costs you only the modest monthly difference for the years you didn't need. Buying too short costs far more: when the term ends, you either renew at annual prices that climb steeply with age, or apply again at an older age with whatever health history the intervening years brought. Nobody knows their health at fifty-five when they're thirty. The longer term buys certainty against that.

The price difference, honestly

For a healthy applicant in their late twenties or thirties, the monthly gap between a 20-year and a 30-year term is usually modest; the carrier is adding years that are still relatively low-risk. The gap widens for applicants in their forties, because the added years reach into the sixties. If the 30-year price makes you want to cut coverage to afford it, don't; a 20-year term at the right amount beats a 30-year term at half the amount. Coverage amount protects your family more than an extra decade of term does.

Laddering: two policies instead of one

Needs shrink over time. Twenty years from now the mortgage is smaller and the children are older, so you need less coverage than you do today. Laddering matches that shape: a larger policy with a shorter term, stacked on a smaller policy with a longer term. A $1.5 million 20-year policy plus a $500,000 30-year policy often costs less than a single $2 million 30-year policy and leaves you with exactly the coverage you need in each decade. The cost is a second application and a little more to manage. It's worth asking about when the total is above $1 million.

Conversion, the safety valve

Many term policies include a conversion option: within a set window, often the first ten to twenty years or up to a certain age, you can convert some or all of the coverage to a permanent policy without new health questions. If a permanent need appears later, such as a dependent with a lifelong condition or an estate that's grown, conversion lets you keep coverage regardless of health. Check the window before you buy; it's one of the few policy features that matters more than price.

Choosing in practice

The estimator on the home page suggests a term based on the income-replacement years you enter. Treat that as the floor. Then ask the quick test above, and if it's close, take the longer option. In the application you can see the price for each term side by side before you commit, which is the right moment to decide.
