Term insurance is a type of coverage that is limited to a specific period of time and cannot be renewed. This means that once the term ends, the insurance expires and the insured is no longer covered. Unlike permanent life insurance, term insurance does not accumulate cash value over time. It is a cost-effective option for those who need coverage for a specific period of time, such as during their working years or to cover a mortgage. However, it is important to review and renew term insurance policies periodically to ensure that they still meet the insured's needs.
