Utilization rate
The percentage of days in a period that fleet vehicles are out on rent — the headline KPI for fleet productivity and the basis for buy, sell, and pricing decisions.
Utilization is calculated as rented days divided by available days, expressed as a percentage. A 10-car fleet in a 30-day month has 300 available car-days; if those cars are rented for a combined 210 days, utilization is 70%. Some operators compute it on fleet-wide totals; mature ones segment by vehicle class, location, and channel (direct vs OTA) — the average hides which assets carry the business.
What 'good' means depends on the segment. Tourist-market operators commonly run 80%+ in peak season and 30–40% in shoulder; long-term/corporate fleets target a flatter 70–85% year-round. Above ~90% sustained, fleet operators usually lose bookings to availability — the next car was unavailable and the customer went elsewhere. Below 50% over a quarter signals oversupply: the fleet is too large, the prices too high, or the distribution mix too narrow.
Utilization directly drives the two biggest fleet decisions: when to expand the fleet (consistently >85% across a quarter and turning bookings away) and when to defleet (consistently <50% off-season with prices already cut). In renviq, utilization is computed live from the booking calendar — by vehicle, class, and location — so the question 'is this fleet sized correctly?' has a number behind it instead of an opinion.
