How it works
Cost Per Mile Calculator: inputs, formula, and result
Enter the values that describe your high priority scenario. The interactive result changes as the inputs change, helping you compare fuel efficiency, fuel consumption, fuel cost, or operating impact.
Formula
Cost Per Mile = Fuel Price ÷ Vehicle MPG
Worked example
At $3.50/gallon and 30 MPG: cost per mile = $3.50 ÷ 30 = $0.117. A 360-mile trip costs $42.00.
Pro tip: Compare your cost per mile to the IRS standard mileage rate ($0.70/mile for 2026). If your fuel cost alone exceeds $0.20/mile, consider a more efficient vehicle.
