About Gas Prices in Colorado
Gas prices in Colorado are reported weekly by the U.S. Energy Information Administration (EIA) from its survey of fuel retailers. The price shown is a statewide average for regular unleaded gasoline. Prices at individual stations in Colorado may be higher or lower depending on location, brand, and local competition.
Several factors influence Colorado'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 Colorado price affects your commute, road trip, or monthly driving budget.
Colorado Fuel Taxes: ≈26¢/gal incl. fees
Colorado has a low nominal gas tax with new road-usage fees. Colorado's base gas tax of 22 cents per gallon has not changed since 1991 — one of the longest freezes in the country. Since 2022, the state has layered small road-usage fees on top, bringing the effective rate to roughly 26 cents and scheduled to rise gradually.
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 Colorado Gets Its Gasoline
Colorado depends heavily on the single Suncor refinery in Commerce City plus pipelines from the Gulf Coast and mid-continent. When Suncor has problems — as in the winter 2022–23 shutdown — Front Range prices can spike far above the national average until supply reroutes. The state's distance from major refining centers makes those episodes slow to resolve.
Where Gas Is Cheapest and Most Expensive in Colorado
Denver and the Front Range corridor usually sit near the national average, but mountain resort towns like Vail, Aspen, and Steamboat Springs run 40–80 cents higher due to trucking costs and captive demand. Fill up before heading into the high country.
