Where Is the Cheapest Gas in the United States?

filling up fuel tank

The cost of gasoline is a major budget item for most households, especially those who have long commutes to work or school. Reducing your miles on the road may not an option, so finding the lowest fuel costs is one way to save money.

Gas Price Variation by Geographic Location

The cost of gasoline definitely varies across the United States. Typically, the cheapest gas across the United States is found near refineries that have access to pipelines and that have lower taxes on the gas itself.

State Fuel Cost Considerations

The southern and midwestern states are often lower-priced, both because of proximity to oil refineries and drilling operations and relatively low tax rates.

  • According to the Motley Fool, Alabama, Louisiana Mississippi, South Carolina and Tennessee typically have the lowest gas prices because "they are closer to America's oil-refining center along the Gulf Coast." However, occasional natural disasters, such as floods or hurricanes, can disrupt production and cause prices to rise even in these areas.
  • Gasoline taxes do play a significant impact in the price of oil, so not all oil-rich states have fuel prices on the low end of the spectrum. According to Motley Fool, high taxes are a key reason why "top oil-producing states like Texas and North Dakota aren't among the states with the lowest gas prices."

The GasBuddy website displays the current average cost of a gallon of regular unleaded gas price by state.

The site also provides pricing trends by comparing data to last week, month and year.

City Versus Rural Locations

In general, gas prices are higher in big cities as compared to rural areas, regardless of state. Using the Gas Buddy Price Heat map for a display and expanding the state map of Texas, for example, reveals that the cities of Austin, San Antonio and Fort Worth typically have higher prices than outside of the city.

Factors Impacting Regional Gas Prices

The U.S. Energy Information Administration (EIA) of the Department of Energy maintains a website that provides information on gas prices by region. It advises that gas prices are determined by many factors such as:

  • Seasonal demand
  • Crude oil supply and prices
  • Gas supply and demand
  • Distance from supplier
  • Retail competition and operating costs
  • Environmental programs
