Estimate how much a trip will cost in fuel based on your vehicle’s fuel efficiency, distance, and gas price. Supports MPG and km/L, gallons and liters, USD or local currency.
Enter the total distance you’ll travel, your vehicle’s fuel efficiency, and the cost of fuel. The calculator multiplies fuel needed by fuel price to give your total fuel cost.
MPG (miles per gallon) is commonly used in the US, while km/L (kilometers per liter) is used in many other countries. The calculator supports both for international use.
Yes, you can choose between one-way or round-trip. The calculator automatically doubles the distance for round-trips.
Assume a fuel efficiency of 25 mpg for a typical car, 500 miles ÷ 25 MPG = 20 gallons needed. 20 × $3.50 = $70.00.
It gives a very close estimate based on your inputs. Real-world variations (traffic, AC use, etc.) may affect actual fuel usage slightly.
Electric vehicles use kWh instead of fuel. This calculator is best for gasoline or diesel-powered vehicles. An EV cost calculator is coming soon.
