Colorado Gas Prices

What drivers in Colorado are paying this week

Colorado stations averaged $4.458 per gallon for regular gasoline in the week ending Oct 26, 2026. The statewide average rose $0.180 from the previous week and sits $0.189 higher than the national average of $4.269. Four weeks ago the state average was $4.094, and a year ago it was $2.797.

Colorado is the only Rocky Mountain state for which the U.S. Energy Information Administration publishes a weekly retail average. Prices track the region closely, with Denver generally a few cents below the mountain benchmark.

Why Colorado gas prices land where they do

• Most supply comes from refineries in Denver, Commerce City, and Salt Lake City.
• The state added a retail delivery fee and clean-transport fees that appear at the pump.
• Mountain driving raises fuel consumption, so per-mile costs run higher than the price suggests.

These are structural factors, not daily noise. They explain why Colorado 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 Colorado compares

Colorado has no bordering state with a published weekly average, so the most useful comparison is the national average of $4.269 and the Rocky Mountain (PADD 4) benchmark of $4.458. The state currently sits $0.189 higher than the national figure.

Ways to spend less on gas in Colorado

1. Membership warehouses such as Costco, Sam’s Club, and BJ’s usually price 10 to 30 cents below nearby branded stations.
2. 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.
3. 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.
4. 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.

Want a number instead of a rule of thumb? The commute cost calculator turns your own miles and MPG into a weekly and annual fuel bill, using the current Colorado price as the default.

How we source Colorado 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 Colorado drivers

At $4.458 per gallon, a 12-gallon fill-up costs about $53.50 in Colorado, compared with $51.23 at the national average. Over a 15,000-mile year at 28 MPG, the state price implies roughly $2388 in fuel — a useful baseline before you start shopping for a cheaper station.
