TERM LIFE INSURANCE has a specified coverage period (term), but can usually be renewed or converted into a permanent policy at the end of a term. Premiums are generally affordable initially, but can increase substantially when renewed.
PERMANENT LIFE INSURANCE is life-long coverage that generally also includes a cash value savings component. There are many types of permanent life insurance, including whole, universal and variable. This type of coverage has higher premiums, but offers more long-term value.
