The Cost of Driving to Buy Low-Price Gas

by Joseph Ganem

With gas prices so high, drivers are much more price conscious when it comes to filling up. It is common to check the Internet or drive around town to find the lowest gas prices. But expensive gas also means it costs more to drive around searching or travel out-of-the-way to the station with lowest price. We all want the best price, but the trip to get it might cost more than the savings.

So for gas savers where is the break-even distance when it comes to buying gas? The calculator on this page will figure that out. For example consider a car with a tank size of 15 gallons and it travels 20 miles for every gallon of gas consumed. Suppose the best price on gas is $3.90 at a distance station compared to $4.05 at a local station. If you enter those values in the calculator it will return a break-even distance of 5.55 miles.

That means that the motorist should not travel more than 5.55 miles out-of-the-way to pay the $3.90 price because that distance results in an 11.1 mile round trip and more than half a gallon of gas worth over $2 burned. The savings are wiped out. Use this calculator to find the break-even distance for the cheapest gas in your area. Try it with numbers for your car and local gas stations.
