About This Calculator
The Fuel Cost Calculator helps you estimate the cost of fuel for your trip. Simply enter the distance you'll travel, your vehicle's fuel efficiency (MPG), and the current fuel price to calculate total fuel cost.
This calculator is perfect for planning road trips, comparing vehicle efficiency, or budgeting for daily commutes. It shows both total cost and cost per mile.
Formula & Calculation Method
Fuel Cost Formula:
Gallons Needed = Distance (miles) / MPG
Total Cost = Gallons Needed × Fuel Price per Gallon
Cost per Mile = Total Cost / Distance
Example: For a 300-mile trip with 25 MPG at $3.50/gallon:
Gallons = 300 / 25 = 12 gallons
Cost = 12 × $3.50 = $42.00
Cost per Mile = $42 / 300 = $0.14
How to Use This Calculator
- Enter Distance: Input the total distance you'll travel in miles.
- Enter MPG: Input your vehicle's fuel efficiency (miles per gallon).
- Enter Fuel Price: Input the current price per gallon of fuel.
- View Results: See gallons needed, total cost, and cost per mile.
Frequently Asked Questions
How do I find my vehicle's MPG?
Check your vehicle's owner's manual, EPA fuel economy ratings, or calculate it by dividing miles driven by gallons used over several fill-ups.
Does this calculator work for metric units?
This calculator uses US units (miles and gallons). For metric (km and liters), you'd use L/100km instead of MPG. 1 MPG ≈ 235.2 L/100km.
What affects fuel cost?
Fuel cost depends on distance, vehicle efficiency (MPG), fuel price, driving habits, traffic conditions, and vehicle maintenance. Aggressive driving can reduce MPG significantly.
