How it works
Cost Per Mile Calculator: inputs, formula, and result
This precise financial tool isolates the fuel cost of driving a single mile by dividing the local price of a gallon of gas by your vehicle's MPG. It breaks down massive fuel budgets into the smallest actionable economic unit.
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.
