Enter Vehicle And Route Data
Use this calculator to compare two vehicles for hauling crews, tools, materials, or site supplies.
Example Data Table
| Vehicle | MPG | Fuel Price | Load Penalty | Idle Hours Weekly | Maintenance Per Mile | Best Use |
|---|---|---|---|---|---|---|
| Light Pickup | 18 | $3.70 | 10% | 2 | $0.16 | Small crew visits |
| Cargo Van | 22 | $3.70 | 8% | 1.5 | $0.14 | Tool transport |
| Heavy Pickup | 13 | $3.95 | 18% | 4 | $0.24 | Material hauling |
Formula Used
Total miles = Trip distance × Trips per week × Weeks
Adjusted MPG = Base MPG ÷ (1 + Load penalty ÷ 100)
Driving gallons = Total miles ÷ Adjusted MPG
Idle gallons = Idle hours weekly × Weeks × Idle burn rate
Total gallons = Driving gallons + Idle gallons
Fuel cost = Total gallons × Fuel price
Total cost = Fuel cost + Maintenance cost + Extra costs
Cost per mile = Total cost ÷ Total miles
How To Use This Calculator

- Add trip distance, weekly trips, and project length.
- Enter load penalty for tools, materials, or trailers.
- Add weekly idle hours and idle fuel burn.
- Add maintenance and extra route costs.

Construction Fuel Planning Guide
Why Mileage Comparison Matters
Fuel cost is a quiet expense on many construction jobs. It grows through daily site visits, supply runs, inspections, crew transport, and equipment support. A small mileage difference can become a large budget gap during a long project. This calculator helps compare two vehicles with the same route plan.
Better Vehicle Selection
Construction fleets often include pickups, vans, service trucks, and trailers. Each option has a different fuel profile. A pickup may carry heavy loads well. A van may protect tools and use less fuel. A larger truck may be required for towing. The best choice depends on both job needs and total cost.
Real Jobsite Conditions
Standard mileage ratings rarely match field conditions. Construction vehicles carry ladders, compressors, fasteners, concrete tools, and crew gear. They may idle during loading, site checks, or cold starts. Traffic, detours, gravel access roads, and stop-and-go routes also reduce mileage. This tool adds load and idle factors for a more practical estimate.
Cost Per Mile Control
Cost per mile is useful for bids and internal planning. It combines fuel, maintenance, and route extras. Managers can compare daily route options with one simple number. A lower fuel bill may not always mean the lowest operating cost. Maintenance and extra fees can change the final choice.
Budget And Bid Support
Contractors can use the result before pricing mobilization, service work, or recurring site travel. The estimate can support fuel allowances and vehicle assignments. It also helps crews choose fewer trips when possible. When trip counts fall, gallons, emissions, and labor waste often fall too.
Smarter Fleet Decisions
Use the comparison before assigning vehicles to long projects. Update fuel prices often. Review load assumptions for each job. Compare light-duty and heavy-duty options. Save the CSV file for records. Export the PDF for simple reporting. Small decisions can protect profit across many weeks.
FAQs
1. What does this calculator compare?
It compares two vehicles by mileage, fuel price, trip distance, idle fuel, maintenance, and extra route costs. It then shows total cost, cost per mile, fuel use, and the lower cost option.
2. Can I use it for construction trucks?
Yes. It is designed for construction routes, crew vehicles, supply runs, service trucks, pickups, vans, and light hauling decisions. Add a load penalty to reflect tools and materials.
3. What is load penalty?
Load penalty is the expected mileage loss from carrying weight, towing, roof racks, tools, or materials. A higher percentage lowers the adjusted mileage and increases estimated fuel use.
4. Why include idle hours?
Construction vehicles may idle during loading, unloading, site checks, traffic waits, or cold starts. Idle fuel can become significant on long jobs, so it improves the estimate.
5. What are extra costs?
Extra costs can include parking, tolls, permits, access fees, special route charges, or other vehicle-specific job expenses. Add one total amount for the project period.
6. Is cost per mile important?
Yes. Cost per mile makes vehicles easier to compare. It combines fuel, maintenance, and extra costs into one value for bidding, scheduling, and fleet planning.
7. Can I download the results?
Yes. Use the CSV button for spreadsheet records. Use the PDF button for a simple printable report that includes the main comparison results.
8. Are the results exact?
No estimate is exact. Actual mileage can change with traffic, terrain, driver habits, weather, load weight, tire pressure, and maintenance condition. Use updated inputs for better planning.
