Truck Gas Calculator
Estimate fuel costs for U-Haul, Penske, and Budget moving trucks.
Enter values to see details.
- Load Smart: Keep 60% of weight near the front (cab) to reduce drag and sway.
- 55 is the Magic Number: Large box trucks lose huge efficiency above 55-60 mph.
- Check Tires: Rental trucks often sit. Check pressure before loading.
Moving to a new home is stressful enough without unexpected fuel expenses. Unlike regular cars, moving trucks and U-Haul rentals consume significantly more gas, and their fuel economy changes drastically based on size, load, and driving conditions.
That’s why using a standard car gas calculator often leads to underestimated fuel costs when moving. This Truck & U-Haul Gas Calculator is built specifically for box trucks and rental vehicles, helping you estimate fuel usage and cost more accurately before your move.
Use the calculator above to plan your moving fuel budget, then read below to understand how truck fuel consumption works and how to avoid surprises.
How Much Gas Does a Moving Truck Use?
Moving trucks typically get far lower MPG than passenger vehicles. While most cars average 25–35 MPG, rental trucks usually fall into much lower ranges.
Typical MPG ranges for moving trucks:
-
10–12 ft truck: 10–14 MPG
-
15–17 ft truck: 8–12 MPG
-
20–26 ft truck: 6–10 MPG
These numbers can vary significantly depending on how heavily the truck is loaded and how it’s driven.
Why Truck Fuel Economy Is So Low
Several factors make moving trucks less fuel-efficient:
-
Large, box-shaped bodies create heavy wind resistance
-
Powerful engines are designed to haul weight, not save fuel
-
Cargo load dramatically increases fuel consumption
-
Frequent stops and city driving reduce efficiency further
This calculator accounts for these realities instead of assuming car-like MPG.
How This Truck & U-Haul Gas Calculator Works
This calculator estimates fuel cost using conservative, real-world assumptions.
It considers:
-
Trip distance – total miles driven
-
Truck size – different box trucks have different MPG ranges
-
Load condition – lightly loaded vs heavily loaded trucks
-
Fuel price – current average gas cost
Based on these inputs, the calculator estimates:
-
Total fuel used
-
Estimated gas cost for the move
The result is a budget-safe estimate designed to help you plan, not underestimate.
How to Use This Truck & U-Haul Gas Calculator
Follow these steps for the most accurate estimate:
-
Enter your moving distance
Include the full distance you expect to drive, including detours. -
Select your truck size
Choose the rental truck or box truck size closest to what you’ll be driving. -
Choose load condition
Select whether the truck will be lightly, moderately, or heavily loaded. -
Enter fuel price
Use an average fuel price for your route or destination. -
Review estimated fuel cost
The calculator displays fuel usage and total cost.
You can adjust inputs to see how load or distance changes affect your budget.
Example: U-Haul Gas Cost for a Long-Distance Move
Let’s look at a realistic example:
-
Truck size: 20 ft U-Haul
-
Distance: 1,000 miles
-
Average MPG (loaded): 8 MPG
-
Fuel price: $3.80 per gallon
Fuel needed: 125 gallons
Estimated fuel cost: $475
This example highlights why moving fuel costs are often higher than expected.
Factors That Increase Truck Fuel Cost
Several factors can raise fuel consumption beyond average estimates:
Heavy Loads
Fully loaded trucks require more engine power, reducing MPG.
Driving Speed
Highway speeds above 60 mph significantly increase fuel use for box trucks.
Terrain and Elevation
Hills and mountainous routes consume more fuel than flat highways.
Stop-and-Go Driving
City traffic and frequent stops lower fuel efficiency dramatically.
Tips to Reduce Gas Cost When Moving
While you can’t eliminate fuel costs entirely, you can reduce them by:
-
Packing efficiently to reduce unnecessary weight
-
Driving at steady speeds
-
Avoiding aggressive acceleration
-
Planning routes with fewer stops and less congestion
-
Combining trips whenever possible
Small changes can save a noticeable amount on long moves.

Frequently Asked Questions
What MPG does a U-Haul truck get?
Most U-Haul trucks average between 6 and 14 MPG, depending on size and load.
Does load really affect fuel usage?
Yes. Heavily loaded trucks consume significantly more fuel than lightly loaded ones.
Should I budget extra for fuel when moving?
Yes. It’s wise to budget slightly higher than the estimate to account for detours and driving conditions.
Can I use a regular gas calculator for moving trucks?
Car-based calculators often underestimate fuel cost for trucks. A truck-specific calculator is more accurate.
Final Thoughts
Fuel costs are one of the most underestimated expenses when moving. A Truck & U-Haul Gas Calculator helps you plan realistically, avoid surprises, and budget with confidence.
By accounting for truck size, load, and distance, this calculator gives you a clearer picture of what your move will actually cost in fuel — so you can focus on settling into your new home, not worrying about gas receipts.
