Midwest Region Gas Price History
The EIA does not publish weekly prices for Wisconsin, so this chart shows the Midwest regional average for regular gasoline, the same series behind the Wisconsin price above. The region also covers Illinois, Indiana, Iowa, Kansas, Kentucky, Michigan, Missouri, Nebraska, North Dakota, Oklahoma, South Dakota, and Tennessee, so the line describes the region as a whole, not Wisconsin alone. The latest week is $1.40 a gallon higher than a year earlier.

About Gas Prices in Wisconsin
The U.S. Energy Information Administration (EIA) surveys fuel retailers weekly but doesn't publish a separate price for Wisconsin, so the price shown is the EIA's Midwest regional average for regular unleaded gasoline. Prices at individual stations in Wisconsin may be higher or lower depending on location, brand, and local competition.
Several factors influence Wisconsin'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 Wisconsin price affects your commute, road trip, or monthly driving budget.
Wisconsin Fuel Taxes: ≈33¢/gal
Wisconsin has a slightly above-average state gas tax. Wisconsin charges about 33 cents per gallon including the petroleum inspection fee. The rate has been frozen for years — Wisconsin ended automatic indexing in 2006 — leaving it modestly above the national median but stable and predictable.
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 Wisconsin Gets Its Gasoline
Wisconsin has no large refineries of its own (the small Superior refinery serves the far northwest). Most fuel arrives by pipeline from Chicago-area and Twin Cities refineries, giving the state solid Midwest supply economics. A unique quirk: Wisconsin's Unfair Sales Act generally requires fuel to be marked up over cost, which limits how aggressively stations can discount.
Where Gas Is Cheapest and Most Expensive in Wisconsin
Milwaukee and Madison usually track the Midwest average closely. Northern Wisconsin pays a trucking premium of 5–15 cents, and prices near the Illinois border are set competitively to capture Illinois drivers fleeing Chicago-area taxes.
