Average rental fleet measures the average number of vehicles in a car-rental company's fleet during a reporting period under the issuer's methodology.
Avis Budget reports Average Rental Fleet. Hertz reports Average Vehicles and Average Rentable Vehicles.
Fleet size is the capacity base
Rental demand cannot be interpreted without knowing how many vehicles were available to serve it.
Avis Budget reported an average rental fleet of 664,638 vehicles in the second quarter of 2026, down 5% from the prior-year quarter.
Hertz separately reports average rentable vehicles, excluding vehicles already on retail lots or actively being sold through other disposition channels.
A smaller fleet can support similar rental volume if utilization improves.
Average fleet is different from ending fleet
A quarter-end snapshot can be distorted by seasonal purchases or dispositions.
An average captures more of the fleet actually used across the period.
Even then, methodologies differ.
Hertz changed its average-rentable-vehicle methodology in 2026 to use a daily average, which it said was more accurate than its prior simple average of beginning and ending balances.
Fleet growth is not automatically positive
Adding vehicles can support demand and market share, but it also increases depreciation, interest, maintenance, storage, and residual-value exposure.
Fleet growth that outpaces demand can reduce utilization and revenue productivity.
That is why average fleet should be read with Car Rental Vehicle Utilization and fleet cost per unit.
Fleet mix matters
Vehicle age, model, class, acquisition channel, manufacturer programs, electric-vehicle exposure, and expected resale value can materially change fleet economics even when vehicle count is unchanged.
Two companies with identical fleets by unit count can therefore have very different capital and depreciation profiles.

Average rental fleet is most useful as the vehicle-capacity base for analyzing utilization, revenue productivity, and fleet cost.
