How to Use This Calculator
Enter your distance, MPG, and gas price for a quick fuel cost estimate. Use Full Trip to add hotels and food. Use Compare Routes to weigh two different routes including tolls. The Professional tab handles up to 4 legs, car rental, EV option, and per-person split.
Formula
Fuel Cost = (Distance ÷ MPG) × Gas Price
EV Cost = (Distance ÷ 100) × kWh/100mi × $/kWh
Per Person = Grand Total ÷ Passengers
Example
300 miles, 30 MPG, $3.50/gal → $35 fuel | Full trip (2 nights $120, 3 days $50/person, 2 pax): Grand Total = $335, Per Person = $167.50
Frequently Asked Questions
- Fuel cost = (Distance ÷ MPG) × Gas Price. For a 300-mile trip at 30 MPG with $3.50/gal gas: (300/30) × $3.50 = $35 in fuel.
- Use the Compare Routes tab to weigh distance, fuel economy, and tolls. Sometimes a longer highway route costs less if it avoids heavy tolls or gets better highway MPG.
- Toll costs vary by state and route. For the US, major toll roads charge $0.05-$0.25/mile. Check the official toll authority websites or apps like TollGuru for exact amounts.
- It depends on electricity vs gas prices and EV efficiency. A typical EV uses about 25-35 kWh/100 miles. At $0.13/kWh and 28 kWh/100 mi: 300 miles = $10.92, versus $35 for gas at 30 MPG/$3.50.
- The per-person cost splits fuel, tolls, parking, and rental evenly. Two passengers traveling 600 miles at $70 total fuel cost each pay $35 — matching a bus ticket at a fraction of the price.
