## What Are Fleet Management KPIs?

Fleet management KPIs (key performance indicators) are the few numbers that show whether your fleet is costing more or less, being used well and running safely: cost per kilometre, utilization, fuel economy, idle time, safety events, maintenance on time, compliance and on-time service. Each one is a simple ratio, and most of the inputs come straight from your telematics devices.

A KPI is only useful if it is measured the same way every month and someone owns it. Pick a short list, write down the formula, and compare each vehicle, driver and depot against its own past results. This guide gives the formula for each KPI and the data that feeds it. It does not give industry targets, because published averages mix fleets with very different vehicles and duty cycles; your own baseline is the fair comparison.

## Which Fleet KPIs Should You Track, and How Are They Calculated?

These are the KPIs most fleets start with, grouped by what they measure. Use kilometres or miles, litres or gallons, but keep the same unit across every report.

| KPI | How to calculate it | Telematics data that feeds it |
| --- | --- | --- |
| Cost per kilometre (or mile) | Total operating cost for the period ÷ distance driven | Odometer distance per vehicle; costs from accounting, fuel cards and maintenance records |
| Fuel economy | Litres used ÷ kilometres driven × 100 (L/100 km), or miles ÷ gallons (mpg) | Fuel used from engine data or fuel card purchases; distance |
| Idle percentage | Idle time ÷ engine-on time × 100 | Engine-on time and idle time per vehicle and driver |
| Utilization | Hours in use ÷ hours available × 100, or days used ÷ working days | Engine hours, trips and days with movement |
| Safety events per 1,000 km | Number of events ÷ kilometres driven × 1,000 | Harsh braking, acceleration and cornering, speeding, seatbelt and dash cam events |
| Preventive maintenance on time | Services done by their due point ÷ services due × 100 | Odometer and engine hours that trigger each service |
| Unplanned repair share | Unplanned repair orders ÷ all repair orders × 100 | Engine fault codes and work orders from maintenance software |
| Vehicle availability | Days a unit was ready for work ÷ days in the period × 100 | Out-of-service dates from maintenance records; trips confirm use |
| Hours-of-service violations | Violations per driver per month | ELD logs from the driver app |
| Unassigned driving | Unassigned driving time not yet assigned or annotated | Movement the ELD recorded with no driver logged in |
| DVIR defects closed on time | Defects repaired or cleared by their deadline ÷ defects reported × 100 | Inspection reports from the driver app and repair records |
| On-time arrival rate | Stops reached inside the promised window ÷ all stops × 100 | Arrival times at customer geofences |

## How Do You Calculate Cost per Kilometre?

Cost per kilometre is the KPI that ties the others together. Add every cost for the period (fuel, maintenance and repairs, tires, insurance, licences and permits, financing or lease payments, depreciation and driver wages if you include them) and divide by the distance driven in the same period. Calculate it per vehicle and for the whole fleet.

Telematics supplies the distance, accurately and per unit, which is the half most fleets estimate. Splitting the cost into fixed and variable parts shows what a change does: idling and speeding move the fuel line, a vehicle that sits for weeks spreads its fixed costs over fewer kilometres. Our cost per mile guide walks through the full calculation.

## How Do You Measure Fleet Utilization?

Utilization tells you whether you own the right number of vehicles and machines. For road vehicles, count the days each unit moved, or its engine hours, against the working days or hours available. For equipment, engine hours are the better measure, because a loader can work all day without travelling far.

Look at the spread, not only the average. A fleet average can look healthy while three units sit unused and two run every hour. Those idle units are the candidates to move to a busier depot, sell or stop renting, and the overworked ones are where the next breakdown will come from.

## Which Fuel KPIs Matter Most?

Track fuel economy and idle percentage together. Fuel economy shows the result; idle percentage and speeding events explain much of the change behind it. Compare vehicles of the same type on similar work, since a loaded tractor and a service van will never share a target.

Add a fuel card exception count if your cards are connected to the platform: purchases where the vehicle was not at the station, or where the litres bought exceed the tank. It is a short list each month, and each line needs an answer.

## How Do You Measure Driver Safety?

Normalize safety events by distance (events per 1,000 km) so a driver who covers more ground is not penalized for exposure. Track the rate per driver and for the fleet, and watch whether it falls after coaching and stays down. Collisions and claims belong in the same report, even though they are rare enough that a single month says little.

Regulators keep their own score. In the US, FMCSA's Safety Measurement System sorts roadside inspection and crash data into categories, and your results there affect inspections and interventions. In Canada, each province runs its own carrier safety rating, such as the CVOR in Ontario. Your internal KPIs should point at the same behaviours those systems record: speeding, hours of service and vehicle condition.

## Which Maintenance KPIs Should You Track?

Start with preventive maintenance done on time, measured against the odometer or engine-hour point that triggered it. Then track the share of repairs that were unplanned and the availability of each unit. When preventive work slips, unplanned repairs and lost days usually follow, and these three numbers show it.

The tracking device sends the odometer, engine hours and fault codes; maintenance software turns them into due dates and work orders. FleetZap, the maintenance software High Point GPS builds and runs, integrates with Geotab and other telematics platforms, so service comes due from real usage and the history needed for these KPIs builds up on its own.

## Which Compliance KPIs Should You Track?

For carriers that run ELDs, track hours-of-service violations per driver, unassigned driving time waiting for review, and DVIR defects closed on time. Each one points to a specific task: a driver to coach, a log to assign or annotate, a repair to finish before the vehicle goes out again.

For IFTA, the useful check is completeness: every vehicle that needs to report has distance recorded in every jurisdiction for the quarter, with no gaps from unplugged devices. A gap found during the quarter is a quick fix; one found during an audit is not.

## How Do You Build a Fleet KPI Report?

Choose a handful of KPIs that match your goals this year, assign an owner to each and review them monthly. Most fleet platforms report idle time, distance, engine hours, safety events and HOS data directly. When you need costs from accounting next to the telematics data, a data connector or an API sends the data to Excel or Power BI, where the full cost per kilometre can be calculated.

High Point GPS is a Geotab partner serving fleets across Canada and the United States, in English and French. We install the tracking devices, set up the rules and reports behind these KPIs and connect the data to the tools your team already uses.

## FAQ

### What are the most important fleet management KPIs?

Most fleets start with cost per kilometre, fuel economy, idle percentage, utilization, safety events per 1,000 km, preventive maintenance done on time and vehicle availability. Carriers with ELDs add hours-of-service violations and unassigned driving, and service fleets add on-time arrivals. Choose the few that match this year's goals and review them monthly.

### How do you calculate cost per kilometre for a fleet?

Add every cost for the period, including fuel, maintenance, tires, insurance, licences, financing or depreciation and, if you choose, driver wages, then divide by the distance driven in the same period. Calculate it per vehicle and for the whole fleet. Telematics devices supply the exact distance for each unit, which is the part most fleets estimate.

### How do you measure fleet utilization?

Divide the hours or days each vehicle was in use by the hours or days it was available, then multiply by 100. Engine hours from the tracking device work best for equipment, while days with movement suit road vehicles. Look at each unit, not only the fleet average, to find units that sit unused or work too hard.

### Is there an industry benchmark for fleet KPIs?

Not one that fits every fleet. Published averages mix vehicle types, loads, regions and duty cycles, so a target from another fleet can mislead you. The fair comparison is your own baseline: measure each KPI the same way for a few months, then compare each vehicle, driver and depot against its past results and against similar units.

### Which telematics data feeds fleet KPIs?

A tracking device supplies distance, engine hours, idle time, fuel use where the engine reports it, engine fault codes, harsh driving and speeding events, and arrival times at geofences. The driver app adds hours-of-service logs and inspection reports. Costs come from accounting, fuel cards and maintenance software, and the two are joined in a report.
