How Multiple-Vehicle Fuel Calculator Works
This tool works by running the same distance and price through several vehicles and ranking the vehicles by fuel cost.
- Step 1
Enter a shared distance
Type the miles or kilometers to compare, such as a monthly driving total.
- Step 2
Add vehicles
List each vehicle with its MPG or liters per 100 kilometers (L/100 km) rating.
- Step 3
Enter fuel prices
Use one price for all vehicles or a separate price for diesel and premium fuel.
- Step 4
Compare vehicle costs
The calculator shows cost per mile, cost for the distance, and the gap between vehicles.
Multiple-Vehicle Fuel Calculator Formula
The formula prices one distance for each vehicle and compares the results.
Cost per Mile = Price per Gallon ÷ MPG
Vehicle Cost = Distance × Cost per Mile
Cost Gap = Vehicle Cost (highest) − Vehicle Cost (lowest)
- Distance
- = shared distance used for every vehicle
- Cost per Mile
- = fuel cost of one mile in that vehicle
Worked Example
- A family compares 3 vehicles over 500 miles (805 km) per month at $3.50 per gallon.
- Sedan at 34 MPG: $0.103 per mile → $51.47.
- SUV at 24 MPG: $0.146 per mile → $72.92. Pickup at 17 MPG: $0.206 per mile → $102.94.
- Cost gap between pickup and sedan = $51.47 per month, or $617.65 per year.
Multiple-Vehicle Fuel Calculator Conversion Table
The table compares common vehicle types at $3.50 per gallon, showing cost per mile, cost per kilometer, and cost for 500 miles (805 km).
| Vehicle Type | MPG | km/L | Cost / Mile | Cost / Km | Cost / 500 mi |
|---|---|---|---|---|---|
| Full-size pickup | 17 | 7.2 | $0.206 | $0.128 | $102.94 |
| Large SUV | 20 | 8.5 | $0.175 | $0.109 | $87.50 |

What is a Multiple-Vehicle Fuel Calculator?
A Multiple-Vehicle Fuel Calculator is a comparison tool that calculates fuel costs for several vehicles over the same distance.
Fuel economy ratings alone do not show money. A 7 MPG gap between a 17 MPG truck and a 24 MPG SUV looks small, but over 12,000 miles the gap equals about $720 at $3.50 per gallon. The Multiple-Vehicle Fuel Calculator turns ratings into dollars for a fixed distance.
Owners of 2 or more vehicles use the tool to pick the right vehicle for each trip. Shoppers use the tool to compare models before buying.
What are the uses of a Multiple-Vehicle Fuel Calculator?
There are 4 main uses of the Multiple-Vehicle Fuel Calculator, including trip vehicle choice, car shopping, and business vehicle selection.
