Fuel Cost Per Mile Calculator
Find out exactly how much every mile driven costs in gasoline. Enter your vehicle’s MPG rating and local price per gallon to calculate cost per mile, cost per 100 miles, and total annual fuel expense.
Cost Per Mile Formula Tool
Formula: Cost Per Mile = Gas Price Per Gallon ÷ Vehicle MPG
Average US driver travels 14,000 to 15,000 miles per year.
Exactly $14.00 for every 100 miles driven.
Worked Example:
If regular unleaded gasoline costs $3.50 per gallon and your crossover gets 25.0 MPG:
Over 15,000 annual miles, 15,000 × $0.14 = $2,100.00 spent on gasoline.
Cost Per Mile Matrix at $3.50/Gallon
| Vehicle MPG | Cost Per Mile | Cost Per 100 Miles | Annual Cost (15k mi) |
|---|---|---|---|
| 18 MPG (Truck/V8 SUV) | $0.194 / mi | $19.44 | $2,916.67 |
| 25 MPG (Standard Crossover) | $0.140 / mi | $14.00 | $2,100.00 |
| 32 MPG (Compact Sedan) | $0.109 / mi | $10.94 | $1,640.63 |
| 50 MPG (Hybrid Sedan) | $0.070 / mi | $7.00 | $1,050.00 |
- Confusing fuel cost per mile with total operating cost: Fuel is only one component of driving cost. Depreciation, maintenance, tires, and insurance often add another $0.25 to $0.45 per mile.
- Using premium gasoline when not required: Premium (91/93 octane) costs $0.60 to $0.90 more per gallon. Unless your owner’s manual states "Premium Required," using premium will increase your cost per mile with zero efficiency gain.
