About Gas Prices in Missouri
The U.S. Energy Information Administration (EIA) surveys fuel retailers weekly but doesn't publish a separate price for Missouri, so the price shown is the EIA's Midwest regional average for regular unleaded gasoline. Prices at individual stations in Missouri may be higher or lower depending on location, brand, and local competition.
Several factors influence Missouri's gas price: state fuel taxes, the distance from major refineries, pipeline and distribution infrastructure, and the required seasonal fuel blend. Use the calculator above to see exactly how today's Missouri price affects your commute, road trip, or monthly driving budget.
Missouri Fuel Taxes: ≈30¢/gal
Missouri has a historically low gas tax that is rising in steps. Missouri had one of the lowest gas taxes in the country for decades. A 2021 law is raising it by 2.5 cents per year, bringing it to roughly 30 cents per gallon by 2026 — still below the national average, and drivers can even claim refunds on the increase for qualifying vehicles.
Tax figures are approximate state-level taxes and fees per gallon of regular gasoline and exclude the 18.4¢/gal federal excise tax. Rates change, so verify current rates with the state's revenue or transportation department.
How Missouri Gets Its Gasoline
Missouri sits at the crossroads of pipelines carrying fuel north from the Gulf Coast and product from Midwest refineries in Kansas, Illinois, and Oklahoma. Abundant, competing supply routes plus low taxes make Missouri one of the cheapest states in the nation for gasoline year after year.
Where Gas Is Cheapest and Most Expensive in Missouri
St. Louis and Kansas City frequently rank among the cheapest large metros in America for gas. Prices are remarkably uniform across the state, with rural areas along I-44 and I-70 staying within a few cents of the big cities.
