Calculate your vehicle's fuel efficiency in MPG (miles per gallon) or Km/L (kilometers per liter), plus total fuel cost and cost per mile/km based on distance traveled, fuel consumed, and price per unit.
Optimize your driving and budget with our free fuel consumption and cost calculator. Enter distance, fuel used, fuel price, and units to get instant MPG or Km/L results, total cost, and cost per mile/km. Includes efficiency tips and a downloadable PNG report for tracking. No signup needed.
MPG = Distance (miles) / Fuel (gallons)
Km/L = Distance (km) / Fuel (liters)
Total Cost = Fuel Used × Price
Cost per Mile/Km = Total Cost / Distance
Distance: 300 miles | Fuel: 12 gallons | Price: $3.50/gallon | MPG → Efficiency: 25 MPG | Total Cost: $42.00 | Cost per Mile: $0.14
Pair with Emergency Fund Calculator for financial planning.
MPG measures miles per gallon (US/Imperial); Km/L is kilometers per liter (Metric).
Total cost = fuel used × price; cost per unit = total cost / distance.
Based on your inputs; real-world factors like driving style affect actual efficiency.
