The life insurance that offers the cheapest rates would be term life insurance, if you need your life insurance coverage to last for a period of 30 years or less.
Term life is temporary coverage lasting for a specific number of years.
Whereas permanent life insurance provides lifetime protection and builds some cash value inside the policy, term life is temporary and only pays out a death benefit if the insured passes away during the policy term.
That's why permanent life insurance may cost up to 5-10 times more than term life for the same amount of life insurance protection.
