How to calculate fuel cost
To estimate the fuel cost of a trip, divide the total driving distance by your vehicle's fuel efficiency. This gives you the amount of fuel required for the trip. Multiply that amount by the current price of fuel to calculate your estimated total cost.
Fuel cost formula
Fuel Needed = Distance ÷ MPG
Fuel Cost = Fuel Needed × Gas Price
Example fuel cost calculation
If you plan to drive 500 miles in a vehicle that averages 30 MPG, you will need approximately 16.67 gallons of fuel. At $3.40 per gallon, the estimated fuel cost for the trip is approximately $56.67.
How can I reduce my fuel costs?
Maintaining proper tire pressure, avoiding unnecessary acceleration, reducing excess vehicle weight, and keeping your vehicle properly maintained can help improve fuel efficiency. Comparing fuel prices before a long trip can also reduce your overall travel costs.
