How Fuel Cost per Mile Calculator Works?
This tool works by dividing the price of 1 gallon of fuel by your vehicle's miles per gallon (MPG). The answer is the fuel cost of driving 1 mile (1.609 km).
Enter the fuel price
Type the price per gallon you pay. The default is $3.75 per gallon, about $0.99 per liter.
Enter the fuel economy
Type the MPG rating of your vehicle. A measured MPG gives a more accurate answer than the sticker value.
Read the cost per mile
The tool shows the fuel cost of each mile, usually between $0.07 and $0.25 for passenger cars.
Scale to any distance
Multiply the cost per mile by any distance. 1,000 miles at $0.15 per mile costs $150.
Fuel Cost per Mile Calculator Formula
The formula is Cost per Mile = Fuel Price ÷ MPG.
Cost per Mile = Fuel Price per Gallon ÷ MPGFormula variables
- Fuel Price per Gallon
- Dollars per US gallon (3.785 L).
- MPG
- Miles traveled on 1 gallon of fuel.
Worked example
- Fuel Price per Gallon: $3.75/gal
- Fuel Economy: 25 MPG
- Divide $3.75 by 25 MPG: $3.75 ÷ 25 = $0.15 per mile.
- Convert to kilometers: $0.15 ÷ 1.609 = $0.093 per km.
Result: $0.15 ($/mile)
Cost per mile covers fuel only. Adding maintenance, tires, insurance, and depreciation raises the full cost of a typical car to $0.50 to $0.80 per mile.
Fuel Cost per Mile Calculator Conversion Table
The table shows cost per mile at 5 fuel prices and 5 MPG ratings.
Rows: Fuel Price per Gallon ($/gal). Columns: Fuel Economy (MPG). Cells: $/mile.
| $/gal | 20 MPG | 25 MPG | 30 MPG | 40 MPG | 50 MPG |
|---|---|---|---|---|---|
| $3.00/gal | $0.15 | $0.12 | $0.10 | $0.08 | $0.06 |
| $3.50/gal | $0.18 | $0.14 | $0.12 | $0.09 | $0.07 |
| $3.75/gal | $0.19 | $0.15 | $0.13 | $0.09 | $0.08 |
| $4.00/gal | $0.20 | $0.16 | $0.13 | $0.10 | $0.08 |
| $4.50/gal | $0.23 | $0.18 | $0.15 | $0.11 | $0.09 |
At $4.00 per gallon, a 20 MPG truck pays $0.20 per mile and a 50 MPG hybrid pays $0.08 per mile.
What is Fuel Cost per Mile Calculator?
The Fuel Cost per Mile Calculator is a tool that shows how much fuel costs for each mile you drive. Cost per mile is the base unit for comparing vehicles, routes, and jobs.
Rideshare drivers, couriers, and sales reps use cost per mile to price work, since income often depends on miles driven. A driver earning $1.00 per mile with a fuel cost of $0.15 per mile keeps $0.85 before other costs.
The tool needs only 2 numbers: fuel price and MPG. The result stays the same whether the drive is 1 mile or 10,000 miles, which makes cost per mile easy to reuse across many calculations.
