What drivers in Missouri are paying this week
Missouri does not have a published weekly statewide average, so the reference number above is the Midwest (PADD 2) average of $4.269. That regional benchmark rose $0.120 week over week and is $0.000 below the national average of $4.269. Stations in Missouri typically trade within roughly 20 to 40 cents of the regional figure, depending on distance from the nearest terminal and local taxes.
Missouri has historically had one of the lowest fuel taxes in the Midwest. A multi-year increase passed in 2021 is still phasing in, so the state remains cheaper than Illinois and Kansas on most days.
Why Missouri gas prices land where they do
- State fuel tax remains below the Midwest average despite recent increases.
- Pipeline access from Oklahoma and Texas keeps wholesale supply competitive.
- St. Louis-area prices reflect Illinois taxes across the river, pulling traffic to Missouri stations.
These are structural factors, not daily noise. They explain why Missouri tends to sit in the same part of the national price range week after week, even when the national average moves. For the general mechanics behind these forces, see our guide on how gas prices are set.
How Missouri compares
Missouri has no bordering state with a published weekly average, so the most useful comparison is the national average of $4.269 and the Midwest (PADD 2) benchmark of $4.269. The state currently sits $0.000 lower than the national figure.
Ways to spend less on gas in Missouri
- Membership warehouses such as Costco, Sam’s Club, and BJ’s usually price 10 to 30 cents below nearby branded stations.
- Stations a few miles off the interstate are often cheaper than the first exit, because they pay less for land and rely on local traffic.
- Apps that show station-level prices are worth using for the last mile — our numbers give you the regional baseline, they give you the address.
- Keeping tires at the recommended pressure and removing roof racks can recover 3 to 6 percent of fuel economy, which is worth 10 to 20 cents a gallon at current prices.

How we source Missouri prices
Every figure on this page comes from the U.S. Energy Information Administration's weekly retail gasoline survey, which reports average retail prices in dollars per gallon including taxes. We rebuild the page every week after the survey is released, so the date on the price panel always matches the data behind it. We do not estimate missing state numbers; where the EIA does not publish a statewide series, we label the regional benchmark instead. Full details are in our methodology and data sources pages.
The bottom line for Missouri drivers
At the regional benchmark of $4.269 per gallon, a 12-gallon fill-up in Missouri costs about $51.23. Over a 15,000-mile year at 28 MPG, that implies roughly $2287 in fuel, before any local station discounts.
Missouri gas price FAQ
What is the average gas price in Missouri right now?
The U.S. Energy Information Administration does not publish a weekly statewide retail average for Missouri. The closest official benchmark is the Midwest (PADD 2) average, which was $4.269 per gallon for the week ending Oct 26, 2026. Local station prices in Missouri typically fall within roughly 20 to 40 cents of that regional figure.
Is gas cheaper in Missouri than the national average?
Missouri is compared against the Midwest (PADD 2) benchmark rather than a statewide number. The region averaged $4.269 versus the national average of $4.269, so Missouri stations are best described as tracking below the national figure.
Why are gas prices low in Missouri?
State fuel tax remains below the Midwest average despite recent increases. Pipeline access from Oklahoma and Texas keeps wholesale supply competitive. St. Louis-area prices reflect Illinois taxes across the river, pulling traffic to Missouri stations. These factors matter more than the national average in determining what local stations charge, because fuel markets are regional, not national.
Where can I find the cheapest gas in Missouri?
Station-level pricing is not part of the EIA dataset, so we do not publish a cheapest-station list. In practice, the lowest prices in Missouri are usually at membership warehouses, at high-volume stations on secondary roads rather than interstate exits, and at stations in lower-cost suburban counties. Use a station-level price app for the final address and our Missouri benchmark to judge whether the price you see is reasonable.
Will gas prices go down in Missouri?
Nobody can forecast a specific week with confidence. What can be said is mechanical: Missouri prices follow crude oil costs, regional refining capacity, seasonal fuel specifications, and local taxes. When crude falls and refineries run normally, prices usually follow within two to four weeks. When a refinery goes down or a hurricane threatens the Gulf Coast, the move can reverse within days.
