Fleet Utilization Calculator — Asset Utilisation Rate
Calculate your fleet utilization rate — what percentage of available capacity is generating revenue. Identify idle trucks, underutilized trailers and cost-per-available-hour.
Quick answer: Fleet utilization = Revenue hours ÷ Available hours × 100. Target 80–90% for trucks, 85–95% for trailers. Below 70% suggests excess capacity or dispatch inefficiency.

How to Use This Calculator
- Enter fleet size and schedule — total trucks and operating schedule (days/year, hours/shift).
- Enter actual revenue hours — hours per truck that the truck is earning revenue — from your TMS or ELD data.
- Enter annual cost per truck — all-in cost including driver, fuel, maintenance and depreciation.
- Review idle asset cost — this is the cost of underutilized capacity — useful for right-sizing decisions.
Worked Example
15 trucks, 260 days × 10 hrs = 2,600 available hours. Avg 1,950 revenue hours/truck. $95,000 annual cost/truck.
- Utilization: 1,950 ÷ 2,600 = 75%
- Idle hours per truck: 650 hrs/year
- Cost per available hour: $95,000 ÷ 2,600 = $36.54/hr
- Fleet idle cost: 650 × $36.54 × 15 = $356,265/year
Frequently Asked Questions
For-hire carriers target 80–90% utilization. Below 70% suggests excess capacity. Private fleets often run 60–75% utilization by design — they're sized for peak demand, not average. Trailer utilization should be higher than truck utilization (85–95%) since trailers don't need drivers.
