The Fuel Cost Formula

To calculate how much you will spend on fuel, determine the total volume of fuel required by dividing distance by fuel efficiency, and then multiply by the price of fuel.

DistanceTotal distance of the trip (miles or km)
Fuel EconomyVehicle fuel efficiency (MPG or km per liter)
Price per UnitCost of fuel per gallon or per liter

Manual Step: Calculating Fuel Cost

Let's calculate the fuel cost for a 300-mile road trip in a vehicle with a fuel economy of 30 MPG, when gas costs $3.50 per gallon.

1
1. Calculate Fuel Needed
Divide total trip miles by the vehicle's miles per gallon.
2
2. Multiply by Fuel Price
Multiply the gallons of fuel required by the price per gallon.
3
Resulting Fuel Cost
The total cost of fuel for your road trip is $35.00.
