Calculate Gas Cost for Any Trip
Enter your trip distance, vehicle MPG, and local gas price to see total fuel cost. Compare gas vs electric.
Calculating Fuel Cost
The formula: Trip Distance ÷ Vehicle MPG × Gas Price = Fuel Cost. A 300-mile trip in a 28 MPG car at $3.50/gallon costs approximately $37.50. For a round trip, double it: $75.00. This simple calculation helps budget road trips, compare driving vs flying, and evaluate the cost difference between vehicles.
Gas vs Electric Cost Comparison
The average gas car costs $0.12-0.18 per mile in fuel. The average EV costs $0.03-0.05 per mile in electricity. On a 300-mile trip: gas car $37-54, EV $9-15. Annual savings for an EV driven 12,000 miles: $840-1,560 in fuel costs alone. However, EV purchase prices remain $5,000-15,000 higher than comparable gas vehicles.
Driving style affects fuel economy by 15-30%. Aggressive acceleration and high-speed highway driving (75+ mph) reduce MPG by 15-20% compared to smooth acceleration and 60-65 mph cruising. Using cruise control on highways improves fuel economy by 5-10%.
