Some insurance companies give you the option to extend your term coverage at a locked in rate or lower face amount of life insurance protection.
If so, your contract will have that in writing.
Most insurance companies allow you to extend your life insurance coverage to a set age, at a much higher rate that can go up annually.
This information would be written right into your life insurance policy. If you no longer have your insurance policy, you can call the insurance company to request a copy.
Keep in mind that converting your term life policy to a permanent life insurance policy almost always needs to be done before the term ends.
Sometimes it needs to be done years before the term ends. So become acquainted with your life insurance policy to get the most out of it.
