Gas prices have risen above $4 per gallon nationally, but drivers in some states are paying far more than others. Prices can vary significantly based on state and local taxes, distance from supply, environmental regulations, and local market conditions. California has the highest average gas price in the country at $5.89 per gallon, while states in the Midwest and Gulf Coast regions have prices below $3.50.

Why it matters

The wide disparity in gas prices across the US highlights how various regional and local factors can dramatically impact the cost of fuel for consumers. This information is important for drivers to understand as they budget for transportation expenses, and it also has broader economic implications as high gas prices can strain household budgets and affect consumer spending in different parts of the country.

The details

State gas taxes are a major driver of price differences, ranging from about 9 cents per gallon in Alaska to 71 cents in California. Distance from supply is another key factor, as prices are generally higher the farther gasoline has to travel. Some parts of the country also require special reformulated gas blends to reduce smog, which adds to production and distribution costs. Local market conditions like the number of gas stations and demand levels can also influence pricing at the pump.

  • The national average for a gallon of regular gas is now $4.06, up from $2.98 before the recent Iran conflict.
  • In March 2025, state taxes, fees and environmental compliance costs added about $1.44 per gallon in California.
