Fleet utilisation
Fleet utilisation is the share of time a vehicle earns money, and the headline rental profitability metric. Calculated as (rented days / available days) × 100.
Definition
Fleet utilisation (utilisation rate) is the percentage of days a vehicle is rented and earning, relative to all available days (minus service, repairs and the off-season). It's the core rental KPI: lower utilisation means a lower return on the fleet.
How it works
Formula: utilisation = (rented days / available days) × 100. 'Available days' = total − maintenance − repairs − seasonal closure. Example: a vehicle available 350 days a year (15 days in service) and rented for 245 days. Utilisation = 245/350 = 70%. A full utilisation report shows the fleet average, each vehicle and the trend over time. The vehicles with the lowest utilisation are sale candidates; very high utilisation leaves no buffer and raises overbooking risk.
Why it matters for a rental company
Utilisation tells you whether the fleet pays its way. A few percentage points more noticeably improves fleet profitability. It guides when to buy more vehicles, when to sell and how to set prices.
What OneRental does
OneRental's reports show utilisation for the whole fleet month by month over the last 12 months. Alongside it you get revenue by branch and the 10 vehicles that brought in the most revenue, with each one's booking count. Every one of these reports exports to CSV.
