A term can be 5, 10, 20, or even 30 years. The coverage you can buy for life insurance without a physical exam can cover you up to certain policy amounts. This can be anywhere from $250,000 up to as much as $500,000, because these policy limitations vary greatly from company to company.
Term insurance is the most common type of life insurance and pays out only if you die within the term. For example, you might take out a 25-year policy so your family could claim if you were to die within 25 years. Of course, if you died later, there would be no payout.
