In fleet operations, dispatchers make decisions that directly affect both cost and revenue. Every load, route, and driver assignment has financial consequences. Two metrics often guide these decisions: Profit-Per-Load and Miles-Per-Gallon (MPG). One focuses on earnings, the other on efficiency. Understanding how they work together is essential for tactical dispatching.

What Profit-Per-Load Really Tells You

Profit-Per-Load measures the net income from a shipment after subtracting all variable costs. These include fuel, driver wages, tolls, maintenance, and layovers. A load that pays $2,500 but costs $2,200 to move yields only $300 in profit. Another that pays $1,800 but costs $1,200 delivers a stronger return. This metric helps dispatchers prioritize loads that contribute more to the bottom line. It’s especially useful in volatile markets where fuel prices or labor costs fluctuate. Relying on rate-per-mile alone can be misleading. Profit-Per-Load offers a clearer view of financial performance.

Why Miles-Per-Gallon Still Matters

MPG measures how efficiently a truck uses fuel. Since fuel is one of the largest expenses in transportation, even small improvements in MPG can lead to significant savings. Factors like vehicle type, load weight, terrain, and driver behavior all influence MPG. A driver who avoids idling and maintains steady speeds will typically achieve better fuel economy. Dispatchers use MPG data to identify inefficient routes, underperforming equipment, or drivers who need coaching. MPG also supports sustainability goals by reducing emissions and fuel consumption.

The False Choice Between Profit and Efficiency

It may seem like dispatchers must choose between high-profit loads and fuel-efficient ones. But these metrics are not in conflict. They complement each other. Profit-Per-Load shows how much a load earns. MPG shows how efficiently that profit is achieved. A load that pays more but burns excessive fuel may not be the better option. A slightly lower-paying load with better MPG could yield higher net profit. Tactical dispatching means balancing both metrics to make informed decisions.

Using Profit-Per-Load in Daily Operations

To apply Profit-Per-Load effectively, dispatchers need real-time data. This includes load revenue and all associated costs. Many transportation management systems (TMS) now calculate Profit-Per-Load automatically. With this data, dispatchers can rank loads by profitability. They can also evaluate brokers, customers, and lanes over time. Some brokers consistently offer high-margin freight. Some lanes deliver better returns than others. Tracking Profit-Per-Load helps dispatchers refine their strategies and focus on what works. Here are some beneficial ways to earn more profit.

How MPG Data Improves Dispatch Strategy

MPG data becomes more valuable when tied to specific drivers, routes, and equipment. If a route consistently delivers poor MPG, it may need to be adjusted. If a driver’s MPG drops, it could indicate mechanical issues or driving habits. Matching the right truck to the right load also improves MPG. Lightweight, aerodynamic trucks are better for long hauls. Heavier-duty vehicles may be reserved for short, high-weight routes. Telematics systems provide real-time MPG data and driver behavior insights. Dispatchers can use this to coach drivers and reward high performers.

Real-World Example: Choosing Between Two Loads

Consider two load options. Load A pays $2,800 for 1,000 miles through mountainous terrain. It’s heavy and fuel-intensive, with an estimated MPG of 5.8 and a projected profit of $600. Load B pays $2,400 for the same distance but is lighter and runs on flat highways. It offers an estimated MPG of 7.2 and a projected profit of $750. Although Load A pays more, Load B delivers higher net profit and better fuel efficiency. A dispatcher using both metrics would likely choose Load B.

Combining Profit and MPG for Tactical Advantage

The best dispatchers don’t treat Profit-Per-Load and MPG as separate. They use both to guide decisions. One method is to create a composite score that combines net profit and expected MPG. Loads with high scores are prioritized. Loads with low scores are reviewed. Another approach is to use Profit-Per-Load for long-term planning and MPG for daily adjustments. Over time, dispatchers can build a network of high-margin lanes and use MPG data to fine-tune assignments. This creates a dispatching process that is both strategic and responsive.

The Role of Technology in Tactical Dispatching

Technology makes these metrics actionable. Modern TMS platforms calculate Profit-Per-Load in real time. Telematics systems provide MPG data, including idle time and route performance. Some tools offer predictive analytics to forecast load profitability and efficiency. Integration is key. When data is siloed, it’s hard to use effectively. When combined in a single dashboard, dispatchers can make faster, more informed decisions.

Training Dispatchers to Use Metrics Effectively

Metrics are only useful if dispatchers know how to apply them. Training should cover how Profit-Per-Load and MPG are calculated and how they influence decisions. Scenario-based exercises help dispatchers practice evaluating trade-offs. For example, comparing two loads with different profit and MPG profiles builds decision-making skills. Aligning incentives with these metrics also improves outcomes. If dispatchers are rewarded only for volume, they may overlook efficiency. Tying incentives to net profit or MPG targets encourages better choices. Leadership should provide regular feedback using dashboards or scorecards. This keeps dispatchers focused on continuous improvement.

Final Thoughts: A Balanced Approach to Dispatching

Profit-Per-Load and Miles-Per-Gallon are not competing priorities. They are complementary tools that provide a complete view of performance. Profit-Per-Load shows the financial return. MPG shows how efficiently that return is achieved. Tactical dispatching means using both metrics to guide decisions, allocate resources, and improve outcomes. With the right tools and training, dispatchers can move beyond guesswork and make informed choices. In a competitive industry, this balanced approach is essential. Fleets that integrate Profit-Per-Load and MPG into daily operations can improve margins, reduce waste, and operate with greater precision.
