What is fleet utilisation?
Fleet utilisation measures how much of a fleet’s available capacity is actually used to move paying cargo. Of all the operational KPIs in a transport company, it’s the one closest to the bank account — because every unused hour, kilometre or pallet of capacity is something you’ve already paid for.
There is no single “fleet utilisation” formula. The number depends on which dimension you measure: time, distance, capacity or revenue.
Four common definitions
| KPI | Formula | What it tells you |
|---|---|---|
| Time utilisation | Active hours ÷ available hours | Are vehicles standing still? |
| Distance utilisation | Loaded km ÷ total km | How much of every km is paid? (inverse of empty miles) |
| Capacity utilisation | Used weight or m³ ÷ vehicle capacity | Are vehicles half-empty? |
| Revenue utilisation | Actual revenue ÷ revenue at full utilisation | The financial bottom line |
A complete picture needs at least the first three.
Why time utilisation alone is misleading
A truck rolling 14 hours a day looks great on time utilisation. If it’s rolling half-empty on the way out and fully empty on the way back, it loses money. Always pair time utilisation with distance and capacity numbers.
Common benchmarks (rough, varies by segment)
- Time utilisation: 70–85% of legal working hours.
- Distance utilisation: 70–80% (i.e. 20–30% empty kilometres).
- Capacity utilisation: 65–85% depending on cargo type.
Big variations across segments: parcel/distribution operate at much higher capacity utilisation than FTL on long-haul, where one full leg + one empty return is common.
What kills utilisation
- Empty return legs – see backhaul.
- Vehicle downtime – breakdowns and unplanned maintenance.
- Driver shortages – truck is fine, no one to drive it.
- Inefficient routing – too much driving for too little cargo.
- Customer-side waiting – wait time at pickup/delivery doesn’t move freight.
- Mismatched fleet – a 24-ton truck used for 8-ton runs.
How to lift utilisation
- Plan with capacity in mind, not just stops. A TMS dispatch board shows what’s left on each vehicle.
- Find return loads systematically.
- Schedule maintenance in dead time, not during peak.
- Right-size the fleet to the actual cargo profile.
- Reduce wait time at customers (booking slots, drop-and-go).
How a TMS supports it
- Per-trip and per-vehicle utilisation calculated from real trips.
- Capacity left visible during planning, not after invoicing.
- Maintenance scheduled inside the Fleet module without surprising the dispatcher.
- Cost-per-utilised-km and -hour, not just absolute cost.
Routix calculates these from the same trip and shipment data used for invoicing — no separate KPI database.
