Semi Truck Fuel Calculator

Fuel costs are one of the biggest expenses in the trucking industry. Whether you operate a single truck or manage an entire fleet, knowing exactly how much you’ll spend on fuel for each trip can significantly impact your bottom line. The Semi Truck Fuel Calculator is a powerful, easy-to-use online tool that helps truckers, logistics managers, and fleet owners estimate total fuel costs, usage, and savings opportunities.

This tool takes into account trip distance, average fuel economy, fuel price, idle time, and the number of trucks and trips, giving you a clear and accurate breakdown of expenses before hitting the road.

How to Use the Semi Truck Fuel Calculator

Using the calculator is simple and takes just a few steps. Follow these instructions to get accurate results:

Step 1: Enter Trip Distance

• Input the total number of miles for your journey.
• This can be a single trip or a round trip.

Step 2: Add Average Fuel Economy

• Enter your truck’s miles per gallon (MPG) rating.
• If unsure, check your truck’s manual or fuel records.

Step 3: Input Fuel Price

• Provide the cost per gallon of diesel at your fueling location.
• Use your most recent purchase or local fuel station prices.

Step 4: Specify Number of Trucks

• Input the total number of trucks making the trip.
• This is especially useful for fleet managers.

Step 5: Set Number of Trips

• Indicate how many trips will be made.
• Works for both daily and scheduled trips.

Step 6: Add Idle Time (Optional)

• If your trucks idle during stops, enter the hours of idle time per trip.
• This helps account for extra fuel consumption.

Step 7: Idle Fuel Burn Rate

• Enter the average gallons per hour (GPH) your truck burns when idling.

Step 8: Click “Calculate”

• The tool shows a short progress animation and then displays a full fuel usage and cost breakdown.

Example Calculation

Let’s say you run 3 trucks, each making 10 trips of 500 miles.

• Fuel Economy: 6 MPG
• Fuel Price: $4.50/gallon
• Idle Time per Trip: 2 hours
• Idle Burn Rate: 1 gallon/hour

Results:

• Total Fuel Cost: $11,250.00
• Total Fuel Needed: 2,500 gallons
• Fuel per Trip (Driving): 83.33 gallons
• Idle Fuel per Trip: 2 gallons
• Cost per Trip: $375.00
• Average Cost per Mile: $0.75

With these insights, you can budget fuel expenses, adjust driving habits, and explore cost-saving strategies.
