Utilisation is the most under-used number in fleet management. Owners obsess over fuel cost and driver behaviour, then quietly run vehicles at 35% utilisation for years. Fixing this single metric is often the largest cost saving available.
What utilisation actually means
Utilisation = (Productive hours ÷ Available hours) × 100
If a vehicle is available 200 hours a month and is productively used for 130 of those hours, utilisation is 65%.
Industry benchmarks
| Tier | Utilisation | |------|-------------| | Excellent | >75% | | Good | 60–75% | | Average | 45–60% | | Poor | <45% |
Why this matters
Financial impact
Every vehicle has fixed costs — financing, insurance, depreciation, registration — that you pay whether the vehicle moves or not. Higher utilisation amortises those costs over more revenue-producing hours.
Right-sizing decisions
Honest utilisation data tells you:
- Which vehicles to retire
- Whether you actually need that next vehicle
- The optimal fleet mix (vans vs. trucks vs. boda-bodas)
Measuring it properly
What you need
- Engine hours (not just kilometres)
- Trips completed
- Days in service vs. days available
- Driver assignment data
Why GPS tracking helps
- Accurate, automatic data — no clipboards
- Historical trending across months and years
- Vehicle-by-vehicle comparisons
- Per-route utilisation breakdowns
Five strategies that move the needle
1. Identify underutilised assets
Look for vehicles with:
- Low daily kilometres
- Few trips per week
- Long idle periods between jobs
- Infrequent active days
2. Optimise scheduling
- Balance workloads across the fleet
- Minimise downtime between trips
- Extend operating hours where demand exists
3. Share resources
- Pool vehicles across departments
- Cross-train drivers across vehicle types
- Run a simple internal vehicle-sharing system
4. Reduce downtime
- Faster maintenance turnaround
- Better spare-parts inventory
- Multiple shifts on the most-used vehicles
5. Right-size the fleet
- Retire vehicles that consistently sit idle
- Replace with appropriately sized units
- Use rental for genuine peak demand instead of owning permanent surplus
What to track monthly
| Metric | Healthy direction | |--------|-------------------| | Average utilisation | Trending up, target >65% | | Vehicles below 40% used | Trending down | | Cost per kilometre | Trending down | | Total fleet size | Right-sized for demand |
Every unused vehicle is money sitting still. Fixing utilisation often funds the entire GPS programme by itself.
