Gas prices vary across the US

As of July 1, 2025, the average price of a gallon of gas in the US is $3.15, down from $3.51 a year prior. However, gas prices vary widely across the country. For instance, West Coast states like California tend to have the highest prices, while the South and Midwest tend to be cheaper. Mississippi and Texas are among the states with the lowest gas prices.

Several factors contribute to these regional variations in gas prices. Local taxes, for instance, play a significant role, with states levying different fuel tax rates. Transportation costs and supply chains also influence prices, as states with limited access to refineries tend to have higher prices. Conversely, states with an abundant local supply often benefit from lower costs. Refinery access can be affected by various factors, including supply disruptions and local regulations.

Additionally, the day of the week can impact gas prices, with Mondays typically being the cheapest day to fill up and Fridays and Saturdays being the most expensive. Using certain credit cards or redeeming rewards points at specific gas stations can also help maximize savings.

Looking at historical trends, gas prices have generally been on a downward trajectory since 2022 due to slowing demand. The Energy Information Administration (EIA) projected that Brent crude oil spot prices would average $74 per barrel in 2025, down from $80 in 2024. This decrease in oil prices is expected to translate to lower gas prices, with the EIA forecasting an average price of $3.20 per gallon in 2025.

Factors influencing price

The cost of a gallon of gas is influenced by several factors, including:

Crude Oil Prices

The price of crude oil is the primary factor influencing gasoline prices. Crude oil is the raw material used to make gasoline, so its cost significantly impacts the final price at the pump. In recent years, crude oil prices have accounted for around 50% of the price of gasoline, with fluctuations depending on market conditions and geopolitical events. For example, during the COVID-19 pandemic, crude oil prices dropped sharply, while the Russian invasion of Ukraine in 2022 caused oil and gas prices to surge.

Supply and Demand

Market forces of supply and demand also play a crucial role in determining gasoline prices. When demand exceeds supply, prices tend to increase, and vice versa. This dynamic is influenced by factors such as seasonal demand (e.g., higher demand during summer in the U.S.) and geopolitical events that impact the oil market, such as the situation in Eastern Europe.

Taxes

Federal, state, and local government taxes contribute significantly to the retail price of gasoline. These taxes vary across regions and can include excise taxes, fees for environmental initiatives, and sales taxes. Taxes and fees can account for a substantial portion of the price at the pump, sometimes as high as 14-17%.

Distribution, Marketing, and Retail Costs

The costs of distributing, marketing, and selling gasoline also factor into the retail price. These costs include transportation from refineries to gas stations, blending with other products to meet local specifications, and the operational expenses of gas stations, such as wages, rent, and insurance. Distribution and marketing costs can account for a significant portion of the retail price, with averages ranging from 15.1% to 17.3% in certain years.

Octane Level

The octane level of gasoline, which indicates its resistance to combustion, also influences the price. Refiners charge more for higher-octane fuel, with premium-grade gasoline being the most expensive. The price difference between regular and premium-grade gasoline has generally increased over time, with a significant price gap at the pump.

Local Market Conditions

Gasoline prices can vary across different regions due to local market conditions and regulations. Factors such as access to refineries, local supply and demand dynamics, and local taxes can cause prices to differ between states or even within the same state.

The interplay of these factors determines the price of a gallon of gas, and changes in any one of them can lead to fluctuations in the cost of gasoline over time and across different locations.

How to save on gas

The national average price for a gallon of regular gasoline in the US stands at $3.15, with premium gasoline averaging $3.98 per gallon. However, gas prices vary across states, with California having the highest average price per gallon at $4.38 and Oklahoma the lowest at $2.56.

  • Use gas rewards credit cards and gas apps: Gas rewards credit cards can provide discounts on gas and cash back on convenience store purchases or car washes. Gas apps, such as GasBuddy, AAA, and Gas Guru, can help you find the best gas prices and plan your route accordingly.
  • Join gas station and supermarket rewards programs: Grocery store rewards programs at supermarkets like Safeway, Kroger, Albertsons, and Stop & Shop allow you to earn discounts on fuel at participating gas stations. Warehouse stores like Costco, Sam's Club, and BJ's also offer discounted gas to members.
  • Maintain your vehicle: Keep your vehicle well-maintained and follow the manufacturer's recommendations for regular servicing. Something as simple as keeping your tires properly inflated can improve gas mileage. Worn-out spark plugs, threadbare tires, and clogged air filters force your car's engine to work harder, reducing fuel economy.
  • Practice good driving habits: Aggressive driving, speeding, rapid acceleration, and sudden braking can lower gas mileage and increase wear and tear on your car. Reducing idling and avoiding heavy stop-and-go traffic can also help save gas and reduce air pollution.
  • Plan your trips: Consolidate your errands to reduce time on the road and use map apps to plot out a fuel-efficient route. Try to avoid backtracking and high-traffic routes. Additionally, consider walking, biking, carpooling, or taking public transportation whenever possible.

Gas prices over time

Gas prices have fluctuated over time, influenced by various economic and geopolitical factors. As of June 2025, the average consumer in the United States spends approximately $2,449 on gas annually, with the national average price of regular gasoline at $3.15 per gallon and premium gasoline averaging $3.98 per gallon.

In 2024, gas prices were $1.65 below their highest point, which occurred in 2012 when adjusted for inflation. The impact of inflation on gas prices is significant, as it affects the purchasing power of consumers. For instance, in January 2025, the cost of a gallon of gasoline increased by 1.8% from the previous month, although it was still 0.2% lower than the previous year's price.

Gas prices vary across different states in the US due to factors such as taxes, transportation costs, supply chains, and local regulations. States with higher fuel taxes or limited access to refineries generally experience higher gas prices, while states with lower taxes or a plentiful local supply tend to have lower prices.

Credit card surcharges also impact the price of gas. Gas stations typically charge more for credit card payments than for cash payments to cover the credit card processing fees they incur. However, some stations offer discounts for cash payments or rewards for using specific cards, such as the ExxonMobil Gas Card, which provides ongoing savings at the point of sale.

To make informed decisions and predictions about future gas prices, consumers can utilize tools like GasBuddy, which provides insights into historical and current fuel prices across different regions. By tracking average gas costs, individuals can better understand the economic indicators influencing gas pricing and make more informed choices, especially when planning for travel or considering relocation.
