A renewal premium for car insurance is the premium charged to renew an insurance policy for a vehicle. This premium is typically charged annually, but may be charged more frequently depending on the insurer. The renewal premium may be higher or lower than the original premium, depending on a number of factors, such as the claims history of the policyholder, the length of time the policy has been in force, and the amount of coverage. In some cases, the renewal premium may also be affected by changes in the insurance market, such as an increase in the number of claims filed.
