The Gas Cost Formula

Calculate total gas cost by finding the total trip distance, dividing by the vehicle's fuel efficiency, and multiplying by the local price per unit of fuel.

CostTotal cost of gas for the trip
DOne-way distance of the trip
RRound-trip multiplier (1 for one-way, 2 for round-trip)
FEFuel efficiency/economy of the vehicle (MPG)
PPrice of gas per gallon or liter

Manual Step: Calculating Gas Cost

Let's calculate the total gas cost for a 200-mile round-trip in a vehicle that averages 25 MPG, with gas priced at $3.80 per gallon.

1
1. Calculate Total Distance
Double the one-way distance because it is a round trip.
2
2. Calculate Gas Needed
Divide total distance by fuel efficiency (MPG).
3
3. Multiply by Gas Price
Multiply the gallons of gas needed by the price per gallon.
4
Resulting Gas Cost
The total cost of gas for the round-trip is exactly $60.80.

Frequently Asked Questions

How is gas cost calculated?
Gas Cost = (Distance / MPG) × Gas Price. If it is a round trip, double the distance first.
What is the most accurate way to calculate a trip's gas cost?
Check your vehicle's actual average MPG on the dashboard rather than the EPA rating, and research average fuel prices along your specific route.
How can I reduce gas consumption on a trip?
Maintain a steady speed under 65 mph, ensure tires are properly inflated, remove heavy items from the trunk, and avoid excessive idling.
