Term life insurance, explained completely
How term really works, what happens when it ends, and the two features most buyers never ask about.
How does term life insurance work?
Term life covers you for a set number of years, usually ten to thirty, at a premium that does not change. If you die during the term, your beneficiary is paid. If the term ends and you are still alive, the coverage stops and nothing is returned. It is the cheapest way to buy a large death benefit.
Term life is the most common starting point, and the right answer for most families buying their first policy. It covers you for a defined period — typically 10, 20, or 30 years — at the lowest cost per dollar of death benefit available anywhere.
Why it's so much cheaper
Because most term policies never pay a claim. A healthy 35-year-old buying 20-year term will very probably be alive at 55. The insurer prices that in. Permanent insurance, by contrast, is designed to pay out eventually, so it must cost more.
This is a feature, not a flaw. You're buying protection for the window when your family is most exposed, and you're not paying to fund a savings account inside the policy.
Level term is the standard
In a level term policy, both the premium and the death benefit stay flat for the whole term. $500,000 at $38 a month stays $500,000 at $38 a month for all 20 years. This is what most people mean by term insurance and what you should generally buy.
Watch for two variations. Annual renewable term starts cheap and rises every year — it gets expensive fast. Decreasing term shrinks the death benefit over time, often sold as mortgage protection; you keep paying the same premium for less and less coverage.
Choosing the length
Match the term to the obligation, not to a round number:
- 10-year: a short, specific debt, or bridging to retirement.
- 20-year: the most common choice — covers young children through independence.
- 30-year: a new mortgage, young kids, or a long income runway.
Buying too short is the more common error. If your term ends at 55 and you still need coverage, you're re-buying at 55-year-old rates with 55-year-old health.
The feature almost nobody asks about: convertibility
A convertible term policy lets you exchange it for permanent coverage from the same insurer — without a new medical exam — within a defined window. Your new permanent premium is based on your age at conversion, but your original health rating carries over.
What happens when the term ends
Three things can happen, and only one is good:
- It expires. Coverage stops. You paid for protection you thankfully didn't need — the same as car insurance you never claimed on.
- It renews annually. Many policies renew automatically without new underwriting, but at a sharply higher rate that climbs each year. This is a safety net, not a plan.
- You convert it. If the policy is convertible and you're still inside the window, you move to permanent coverage without proving your health.
Return of premium: usually not worth it
Return-of-premium term refunds your premiums if you outlive the term. It sounds excellent. It typically costs two to three times standard term. Most analyses find that buying standard term and investing the difference leaves you better off — and the refund isn't adjusted for inflation, so the dollars you get back are worth less than the ones you paid.
Who term is right for
Anyone with a temporary, definable need: a mortgage, children to raise, an income to replace during the working years. That's the large majority of buyers. If you also want lifelong coverage or a cash-value component, that's a reason to add permanent insurance — not usually a reason to skip term.
