Enter two numbers. Your results update as you type.
Estimates based on typical results. Actual savings vary by fleet, routes and driving behaviour.
The calculator multiplies your fleet's monthly fuel spend by the savings percentage you set, then compares those savings with the cost of the devices to show the payback period and five-year return.
It starts at 7% because that is a cautious figure. What you actually save depends on how often your vehicles run above the speed you set: long highway routes tend to save more than stop-start city work, where trucks rarely reach the cap.
For a real-world comparison, a six-week trial on 20 trucks in Riyadh recorded 17% less fuel in the group fitted with speed limiters, as reported by the client. Read the Riyadh fuel case study.
Use the result as a starting point. For figures based on your own routes, ask us for a fleet assessment.
