Factors influencing car insurance premium increases

Car insurance premiums are influenced by various personal and driving-related factors. Following an at-fault accident, rates may increase by an estimated 20% to 50% or more. The extent of this increase depends on the severity of the accident, the cost of property damage, and whether injuries were involved. Claims involving medical bills, lost income, and liability payments typically result in higher surcharges than minor property-damage claims.

Beyond driving history, life changes such as divorce, job loss, or changes in credit scores can also impact costs. Divorce often necessitates splitting shared policies, which can lead to the loss of multi-car discounts. Additionally, in most states where permitted, insurers use credit-based insurance scores to predict claim likelihood. According to the National Association of Insurance Commissioners, approximately 95% of auto insurers utilize these scores to determine pricing.
