Fleet Rating
A commercial auto rating method applying a single experience-based rate to all vehicles in a fleet, typically available for 5+ vehicles.
What It Is
Fleet rating is a commercial auto rating methodology where the premium for all vehicles in a fleet is calculated using a single composite rate based on the fleet's overall loss experience, rather than rating each vehicle individually. Most carriers require a minimum of five power units to qualify for fleet rating, though some set the threshold at ten or more.
Under fleet rating, the insurer reviews the fleet's loss history (typically three to five years), calculates a loss ratio, and applies an experience modification factor that increases or decreases the base rate. Fleets with favorable loss experience receive credits that can reduce premiums by 15-40%, while fleets with poor experience may face debits of 25-75% or more.
Fleet rating encourages risk management because the insured's own loss experience directly drives their premium. This creates a financial incentive for fleet operators to invest in driver training, vehicle maintenance, telematics, and safety programs.
Why It Matters for Brokers
Understanding fleet rating is essential for brokers managing transportation and fleet accounts. The ability to demonstrate a client's favorable loss experience and present it effectively to underwriters can result in significant premium savings. Conversely, brokers must help clients with poor experience understand what drives their rating and develop loss control strategies to improve it over time.
Real-World Example
A delivery company with 45 vehicles has a three-year loss ratio of 38%, well below the industry average of 55%. Fleet rating applies an experience credit of -22%, reducing the annual premium from $287,000 to $223,860—a savings of $63,140. The following year, three major at-fault accidents push the loss ratio to 72%, and the renewal comes in at $344,400 with a +20% debit. The broker works with the client on a driver safety program to bring the experience back in line.
Common Mistakes
- 1Not providing complete five-year loss runs to underwriters, which may result in the fleet being rated at manual rates instead of receiving available experience credits.
- 2Failing to separate comprehensive losses (theft, hail) from at-fault collision losses when presenting fleet experience—comprehensive losses are typically weighted less heavily.
- 3Not advising fleet clients to invest in safety programs and telematics that can demonstrably improve loss experience and reduce premiums at renewal.
