The formula is simple: Fuel Cost = (Miles Driven ÷ MPG) × Gas Price
Example: If you drive 300 miles/week, your car gets 25 MPG, and gas costs $3.50/gallon:
- Weekly gallons: 300 ÷ 25 = 12 gallons
- Weekly cost: 12 × $3.50 = $42
- Monthly cost: ~$182
- Annual cost: ~$2,184

Frequently Asked Questions
How is fuel cost calculated?
Fuel cost = (Miles driven per year ÷ Fuel efficiency) × Gas price. For monthly costs, divide the annual figure by 12.
What is a good fuel efficiency rating?
For gas-powered cars: 25 MPG city / 30+ MPG highway is average. 40+ MPG is excellent. Hybrids typically get 50+ MPG.
How can I improve my fuel efficiency?
