Fleet utilisation and unit cost: practical guide

This guide explains how to use the Count.ie fleet utilisation and unit cost. Measure productive vehicle usage, availability, downtime and operating cost. Follow the inputs, method and worked example below, then compare your own scenario.

What to prepare

  • Gather order history, item dimensions, weights and supplier lead times.
  • Identify the same units and planning period across stock, demand and capacity inputs.
  • Check which freight, storage, import or production costs the model includes.

Understand the inputs

The calculation method

Utilisation = productive hours ÷ scheduled fleet hours. Availability excludes downtime; unit costs divide the period cost by activity.

Worked example

Illustrative inputs and their result.

Example inputs

Vehicles in fleet
8
Scheduled hours per vehicle in period
160
Total productive fleet hours
900
Total breakdown or maintenance hours
100
Total fleet kilometres
32000
Total fleet cost for period (€)
26000

Calculated example result

Utilisation Percent
70.31%
Availability Percent
92.19%
Fleet Cost Per Km
€0.81/km

How to interpret the result

A capacity, inventory or landed-cost estimate is not a guarantee of service availability. Variability in demand, lead time, packing and customs treatment can change the operating result.

Keep the service requirement fixed while testing demand, lead time or shipment size. Check practical constraints such as handling, access and supplier minimum quantities separately.

Common mistakes to avoid

  • Do not mix usable capacity with nominal capacity.
  • Keep net goods weight separate from packaged or shipping weight.
  • Do not treat a supplier's usual lead time as a guaranteed maximum.

Assumptions and sources

Hours and costs must use the same period; productive and downtime hours are fleet totals rather than per-vehicle values.

If your case falls outside this scope, use a more suitable calculator or contact us about an unclear method.
