Free Idle Time Report
An idle time report that turns engine-idle hours into wasted fuel and dollars per vehicle and driver, so the most expensive idlers are obvious and coaching has a target. Use it alongside our fleet calculators to size the costs this template tracks, or browse fleet management software when you are ready to automate the workflow. See all downloads in the template library, and check the fleet glossary for any unfamiliar terms.

- Idle hours per vehicle and driver over the reporting period
- Idle percentage (idle hours ÷ total engine hours) to compare units fairly
- Estimated fuel wasted and dollar cost based on an idle burn rate you set
- A ranking view so the worst idlers rise to the top for coaching

How to use it
- 1
Pull idle hours and total engine hours per vehicle from your telematics export.
- 2
Enter your assumed idle fuel burn (typically around 0.5–0.8 gal/hr for a heavy truck) and fuel price.
- 3
Let the sheet compute idle %, gallons wasted, and dollar cost per vehicle.
- 4
Sort by cost to find the units and drivers worth coaching first.
- 5
Re-run the report monthly and track whether idle % is trending down after intervention.

Idle Time Report
Idle fuel ≈ idle hours × burn rate (gal/hr). Idle % = idle hours ÷ total engine hours. Burn rate varies by engine; tune it to your fleet.
| Vehicle | Driver | Engine Hours | Idle Hours | Idle % | Gal Wasted | Idle Cost ($) |
|---|---|---|---|---|---|---|
| TRK-007 | J. Alvarez | 168.0 | 52.0 | 31% | 31.2 | 112.32 |
| TRK-011 | S. Park | 172.0 | 21.0 | 12% | 12.6 | 45.36 |
Frequently asked questions
Quick answers to the questions buyers usually ask once the category, software, or rollout details start getting more specific.
A heavy-duty engine can burn roughly half a gallon to nearly a gallon of fuel per hour at idle while producing zero miles. Across a fleet, idle hours quietly add up to thousands of wasted gallons and accelerated engine wear.
Benchmarks vary by duty cycle and climate, but many fleets aim to drive idle time well below 20–25% of engine hours. The right target is your own trend. Measure first, then set a goal to reduce it.
Multiply idle hours by an assumed idle burn rate in gallons per hour. The burn rate depends on engine size, load (HVAC, PTO), and conditions, so tune the figure to your fleet rather than using a single industry number.
Combine driver coaching using the per-driver ranking, idle-shutdown policies, and where justified, auxiliary power units or cab heaters that cut the need to idle for comfort. Measure before and after to prove the change.
