What gets measured, gets managed. The trap most fleet managers fall into is measuring everything and managing nothing. The fleets that improve quarter-on-quarter pick a small number of KPIs, watch them every week, and respond to what they see.
Financial KPIs
Cost per kilometre
Cost per km = Total operating cost ÷ Total kilometres
Includes fuel, maintenance, insurance, depreciation. Track the trend, not just the absolute number.
Cost per vehicle
Cost per vehicle = Total fleet cost ÷ Number of vehicles
Useful for budgeting and for spotting outlier vehicles.
Fuel cost per kilometre
Fuel cost per km = Total fuel cost ÷ Total kilometres
Critical for early-warning on efficiency drift.
Operational KPIs
Fleet utilisation rate
Utilisation = Productive hours ÷ Available hours × 100
Target: above 65% for most commercial fleets.
Vehicle availability
Availability = Vehicles available ÷ Total fleet × 100
Target: above 95%. Anything below means too much downtime.
On-time performance
On-time = On-time deliveries ÷ Total deliveries × 100
Target: above 95% for delivery operations.
Safety KPIs
Accident rate
Accident rate = Accidents per million kilometres
Compare against your industry baseline.
Safety score
A composite of speeding, harsh braking, and seatbelt use, normalised across the fleet.
Preventable accident rate
The accidents that could have been avoided — these are the ones you can actually act on.
Maintenance KPIs
Preventive maintenance compliance
PM compliance = PM completed on time ÷ PM due × 100
Target: 100%. Anything else compounds into breakdowns later.
Mean time between failures
Average time between unplanned breakdown events. Trending up is good.
Repair-to-PM cost ratio
If repair costs are dwarfing PM costs, your PM programme is too thin.
A weekly dashboard worth running
Create one page that shows:
- Fleet status overview (active, in service, in workshop)
- Top 5 cost drivers this week
- Safety score trend (4-week rolling)
- Maintenance items due this week
- Utilisation summary by vehicle type
If a number changes meaningfully, you act on it before the next week's review.
Setting targets that work
Benchmark properly
Compare against:
- Industry standards
- Your own historical performance
- Peer fleets where you can get data
Use SMART goals
- Specific — name the metric clearly
- Measurable — automatic data, not estimates
- Achievable — stretch but realistic
- Relevant — connected to a business outcome
- Time-bound — reviewed on a fixed cadence
You cannot improve what you do not measure — and you cannot manage what you measure without acting on.
