How to Calculate Fuel Cost
Knowing your trip fuel cost helps you budget for road trips, compare driving vs flying, and evaluate the true cost of your commute.
Example: A 500-mile trip in a 25 MPG vehicle at $3.15/gallon: (500 รท 25) ร $3.15 = $63.00
National Average Gas Prices (2026)
| Fuel Grade | Avg Price/Gal |
|---|---|
| Regular (87) | $3.15 |
| Mid-Grade (89) | $3.55 |
| Premium (93) | $3.95 |
| Diesel | $3.65 |
Prices vary significantly by state. California averages $1.00+/gallon above the national average; states like Texas and Mississippi are typically $0.30 below.
Cost Per Mile Perspective
At $3.15/gallon and 25 MPG, your fuel cost per mile is $0.126. That means even a 10-mile commute costs $1.26 each way, or about $650/year in fuel alone. The IRS standard mileage rate for 2026 is $0.70/mile, which includes all vehicle costs beyond just fuel.
